Do-it-yourself service precautions

If you perform maintenance by yourself, be sure to follow the correct procedures
as given in these sections.

CAUTION:
The engine compartment contains many mechanisms and fluids that may move suddenly,
become hot, or become electrically energized. To avoid death or serious injury,
observe the following precautions:
When working on the engine compartment
Make sure that the indicator on the “POWER” switch and the “READY” indicator
are both off.
Keep hands, clothing and tools away from the moving fans and engine drive belt.
Be careful not to touch the engine, power control unit, radiator, exhaust manifold,
etc. right after driving as they may be hot. Oil and other fluids may also be hot.
Do not leave anything that may burn easily, such as paper and rags, in the engine
compartment.
Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are flammable.
When working near the electric cooling fans or radiator grille
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may automatically
start to run if the air conditioning is on and/or the coolant temperature is high.
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in your eyes.

NOTICE:
If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to
dirt in the air. Also, a backfire could cause a fire in the engine compartment.

Hood

Release the lock from the inside of the vehicle to open the hood.

Pull the hood lock release lever.
The hood will pop up slightly.

Pull up the hood catch and lift
the hood.

CAUTION:
Pre-driving check
Check that the hood is fully closed and locked.
If the hood is not locked properly, it may open while the vehicle is in motion and
cause an accident, which may result in death or serious injury.

Positioning a floor jack

When raising your vehicle with a floor jack, position the jack correctly.
Improper placement may damage your vehicle or cause injury.

Make sure to check the oil type and prepare the items needed before
adding oil.

1. Remove the oil filler cap by turning it counterclockwise.
2. Add engine oil slowly, checking the dipstick.
3. Install the oil filler cap by turning it clockwise.

Engine oil consumption

The amount of engine oil consumed depends on the oil viscosity, the quality of
the oil and the way the vehicle is driven.
More oil is consumed under driving conditions such as high speeds and frequent
acceleration and deceleration.
A new engine consumes more oil.
When judging the amount of oil consumption, keep in mind that the oil may
have become diluted, making it difficult to judge the true level accurately.
Oil consumption: Max. 1.1 qt./600 miles, 0.9 Imp. qt./600 miles (1.0 L per 1000
km)
If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600 miles
(1000 km), contact your Lexus dealer.

After changing the engine oil (USA only)

The engine oil maintenance data should be reset. Perform the following procedure:
1. Display the trip meter “A” , then turn the “POWER” switch off.
2. While pressing the “ODO/TRIP” button, turn the “POWER” switch to
ON mode.

3. Keep the “ODO/TRIP” button pressed for
about 5 seconds. The resetting procedure is
complete when “000000” in the trip meter
flashes once and the message in the multiinformation
display disappears.

CAUTION:
Used engine oil
Used engine oil contains potentially harmful contaminants which may cause skin
disorders such as inflammation or skin cancer, so care should be taken to avoid
prolonged and repeated contact. To remove used engine oil from your skin, wash
thoroughly with soap and water.
Dispose of used oil and filters only in a safe and acceptable manner. Do not dispose
of used oil and filters in household trash, in sewers or onto the ground.
Call your Lexus dealer, service station or auto parts store for information concerning
recycling or disposal.
Do not leave used engine oil within the reach of children.

NOTICE:
To prevent serious engine damage
Check the oil level on a regular basis.
When replacing the engine oil
Be careful not to spill engine oil on the vehicle components.
Avoid overfilling, or the engine could be damaged.
Check the oil level on the dipstick every time you refill the vehicle.
Be sure the engine oil filler cap is properly tightened.

Coolant

The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the engine and hybrid system are cold.

- Engine coolant reservoir

1. Reservoir cap.
2. “FULL” line.
3. “LOW” line.
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.

- Power control unit coolant reservoir

1. Reservoir cap.
2. “FULL” line.
3. “LOW” line.
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.

Coolant selection

Only use “Toyota Super Long Life Coolant” or similar high quality ethylene glycol
based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life
hybrid organic acid technology.
U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% coolant and
50% deionized water. (Minimum temperature: -31°F [-35°C]).
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45%
deionized water. (Minimum temperature: -44°F [-42°C]).
For more details about coolant, contact your Lexus dealer.

If the coolant level drops within a short time of replenishing

Visually check the radiators, hoses, engine/power control unit coolant reservoir
caps, drain cock and water pump.
If you cannot find a leak, have your Lexus dealer test the cap and check for leaks in
the cooling systems.

CAUTION:
When the engine and hybrid system are hot
Do not remove the coolant reservoir cap.
The cooling system may be under pressure and may spray hot coolant if the cap is
removed, causing burns or other injuries.

NOTICE:
When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of water
and antifreeze must be used to provide proper lubrication, corrosion protection
and cooling. Be sure to read the antifreeze or coolant label.
If you spill coolant
Be sure to wash it off with water to prevent damaging to parts or paint.

Radiator and condenser

Check the radiator and condenser and clear any foreign objects.
If either of the above parts are extremely dirty or you are not sure of their
condition, have your vehicle checked by your Lexus dealer.

CAUTION:
The radiators and condenser may be hot after driving
Do not touch the radiator or condenser as they may be hot and burn you.

Brake fluid

Checking fluid level

The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.

Adding fluid

Make sure to check the fluid type and prepare the necessary item.

Brake fluid can absorb moisture from the air

Excess moisture in the brake fluid can cause a dangerous loss of braking efficiency.
Use only newly opened brake fluid.

CAUTION:
When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage painted
surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean water
immediately.
If you still experience discomfort, see a doctor.

NOTICE:
If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear out or
when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, may be a serious problem.

Washer fluid

If any washer does not work or the
warning message appears on the
multi-information display, the
washer tank may be empty. Add
washer fluid.

CAUTION:
When adding washer fluid
Do not add washer fluid when the hybrid system is hot or operating as washer fluid
contains alcohol and may catch fire if spilled on the hybrid system etc.

NOTICE:
Do not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces.
Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the washer fluid tank.

tire rotation is carried out at the
same interval as tire inspection.

The tire pressure warning system

Your Lexus is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire inflation
pressure before serious problems arise.

Installing tire pressure warning valves and transmitters

When replacing tires or wheels, tire pressure warning valves and transmitters
must also be installed.
When new tire pressure warning valves and transmitters are installed,
new tire pressure warning valve and transmitter ID codes must be registered
in the tire pressure warning computer and the tire pressure warning
system must be initialized. Have tire pressure warning valve and transmitter
ID codes registered by your Lexus dealer.

Initializing the tire pressure warning system

The tire pressure warning system must be initialized in the following
circumstances:

When tire inflation pressure is changed such as when changing travelling
speed or load weight
When changing the tire size.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.

How to initialize the tire pressure warning system

1. Park the vehicle in safe place and turn the “POWER” switch off.
Initialization cannot be performed while the vehicle is moving.
2. Adjust the tire inflation pressure to the specified cold tire inflation
pressure level.
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
3. Turn the “POWER” switch to ON mode.

4. Press and hold the tire pressure
warning reset button until the tire
pressure warning light flashes
slowly 3 times.
Wait for a few minutes with the “POWER” switch on and then
turn the “POWER” switch off.

Registering ID codes

The tire pressure warning valve and transmitter is equipped with a unique
ID code. When replacing a tire pressure warning valve and transmitter, it
is necessary to register the ID code. Have the ID code registered by your
Lexus dealer.

When to replace your vehicle’s tires

Tires should be replaced if:
You have tire damage such as cuts, splits, cracks deep enough to expose the
fabric, and bulges indicating internal damage.
A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage.
If you are not sure, consult with your Lexus dealer.

Replacing tires and wheels

If the ID code of the tire pressure warning valve and transmitter is not registered,
the tire pressure warning system will not work properly. After driving for about 20
minutes, the tire pressure warning light flashes for 1 minute and stays on to indicate a
system malfunction.

Tire life

Any tire over 6 years old must be checked by a qualified technician even if it has seldom
or never been used or damage is not obvious.

If the tread on snow tires wears down below 0.16 in. (4 mm)

The effectiveness of the tires as snow tires is lost.

Maximum load of tire

Check that the number given by dividing the maximum load by 1.10 of the replacement
tire is greater than 1/2 of the Gross Axle Weight Ratings (GAWR) of either
the front axle or the rear axle, whichever is greater.

For the GAWR, see the Certification Label.
For the maximum load of the tire, see the load
limit at maximum cold tire inflation pressure
mentioned on the sidewall of the tire.

Tire types

1 Summer tires.
Summer tires are high-speed performance tires best suited to highway driving
under dry conditions. Since summer tires do not have the same traction performance
as snow tires, summer tires are inadequate for driving on snow-covered
or icy roads. For driving on snow-covered roads or icy roads, the use of snow tires
is recommended. When installing snow tires, be sure to replace all four tires.
2 All season tires.
All season tires are designed to provide better traction in snow and to be adequate
for driving in most winter conditions, as well as for use year round. All season
tires, however, do not have adequate traction performance compared with
snow tires in heavy or loose snow. Also, all season tires fall short in acceleration
and handling performance compared with summer tires in highway driving.
3 Snow tires.
For driving on snow-covered roads or icy roads, we recommend using snow tires.
If you need snow tires, select tires of the same size, construction and load capacity
as the originally installed tires. Since your vehicle has radial tires as original
equipment, make sure your snow tires also have radial construction. Do not install
studded tires without first checking local regulations for possible restrictions.
Snow tires should be installed on all wheels.

Initializing the tire pressure warning system

Initialize the tire pressure warning system with the tire inflation pressure adjusted to
the specified level.

If you push the tire pressure warning reset switch accidentally

If initialization is performed, adjust the tire inflation pressure to the specified level
and initialize the tire pressure warning system again.

When the initialization of the tire pressure warning system has failed

Initialization can be completed in a few minutes. However, in the following cases,
the settings have not been recorded and the system will not operate properly. If
repeated attempts to record tire inflation pressure settings are unsuccessful, have
the vehicle inspected by your Lexus dealer.
When operating the tire pressure warning reset button, the tire pressure warning
light does not flash 3 times.
After carrying out the initialization procedure, the tire pressure warning light
flashes for 1 minute then stays on after driving for 20 minutes.

Routine tire inflation pressure checks

The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.

Do not mix differently constructed tires (radial, bias-belted or bias-ply tires).
Do not mix summer, all season and snow tires.
Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
When initializing the tire pressure warning system
Do not push the tire pressure warning reset switch without first adjusting the tire
inflation pressure to the specified level. Otherwise, the tire pressure warning light
may not come on even if the tire inflation pressure is low, or it may come on when
the tire inflation pressure is actually normal.

NOTICE:
Repairing or replacing tires, wheels and tire pressure warning valves and transmitters
When removing or fitting the wheels, tires or the tire pressure warning valves and
transmitter, contact your Lexus dealer as the tire pressure warning valves and transmitters
may be damaged if not handled correctly.
To avoid damaging the tire pressure warning valves and transmitters
Do not use liquid sealants on flat tires.
Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the cushioning
ability of the tires. In addition, driving on rough roads may cause damage to the
tires themselves, as well as the vehicle’s wheels and body.
If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Tire inflation pressure

Tire inflation pressure

The recommended cold tire inflation pressure and tire size is displayed
on the tire and loading information label.

- Type A

- Type B

Inspection and adjustment procedure

1. Tire valve.
2.Tire pressure gauge.

1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge onto the tire valve.
3. Read the pressure using the gauge graduations.
4. If the tire inflation pressure is not at the recommended level,
adjust the pressure.
If you add too much air, press the center of the valve to deflate.
5. After completing the tire inflation pressure measurement and
adjustment, apply soapy water to the valve and check for leakage.
6. Put the tire valve cap back on.

Tire inflation pressure check interval

You should check tire inflation pressure every two weeks, or at least once a month.
Do not forget to check the spare.

Effects of incorrect tire inflation pressure

Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency.
Reduced driving comfort and tire life.
Reduced safety.
Damage to the drive train.
If a tire needs frequent inflating, have it checked by your Lexus dealer.

Instructions for checking tire pressure

When checking tire inflation pressure, observe the following:
Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been driven for
more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure
reading.
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation pressure
that is even just a few pounds off can degrade ride and handling.
Do not reduce tire inflation pressure after driving. It is normal for tire inflation
pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is balanced.

CAUTION:
Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions may occur
and result in an accident causing death or serious injury:
Excessive wear.
Uneven wear.
Poor handling.
Possibility of blowouts resulting from overheated tires.
Poor sealing of the tire bead.
Wheel deformation and/or tire separation.
A greater possibility of tire damage from road hazards.

NOTICE:
When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or moisture could get into the valve and cause air leakage,
which could result in an accident. If the caps are lost, replace them as soon as
possible.

Wheels

If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause a loss of handling
control.

Wheel selection

When replacing wheels, care should be taken to ensure that they
are equivalent to those removed in load capacity, diameter, rim
width, and inset*.
Replacement wheels are available at your Lexus dealer.
*: Conventionally referred to as “offset”.
Lexus does not recommend using the following:
Wheels of different sizes or types.
Used wheels.
Bent wheels that have been straightened.

Aluminum wheel precautions

Use only Lexus wheel nuts and wrenches designed for use with
your aluminum wheels.
When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
Be careful not to damage the aluminum wheels when using tire
chains.
Use only Lexus genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

When replacing wheels

The wheels of your vehicle are equipped with tire pressure warning valves and
transmitters that allow the tire pressure warning system to provide advanced warning
in the event of a loss in tire inflation pressure. Whenever wheels are replaced,
tire pressure warning valves and transmitters must be installed.

CAUTION:
When replacing wheels
Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in loss of handling control.
Never use an inner tube in a leaking wheel which is designed for a tubeless tire.
Doing so may result in an accident, causing death or serious injury.

NOTICE:
Replacing tire pressure warning valves and transmitters
Because tire repair or replacement may affect the tire pressure warning valves
and transmitters, make sure to have tires serviced by your Lexus dealer or other
qualified service shop. In addition, make sure to purchase your tire pressure
warning valves and transmitters at your Lexus dealer.
Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with nongenuine
wheels.

After a fuse is replaced

If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement.
If the replaced fuse blows again, have the vehicle inspected by your Lexus
dealer.

If there is an overload in the circuit

The fuses are designed to blow before the entire wiring harness is damaged.

CAUTION:
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage, and possibly a fire or injury.
Never use a fuse of a higher amperage rating than that indicated, or use any
other object in place of a fuse.
Always use a genuine Lexus fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
This can cause extensive damage or even fire.
Do not modify the fuses or fuse boxes.

NOTICE:
Before replacing fuses
