Your vehicle will handle differently when towing a trailer. Help to avoid an accident, death or serious injury, keep the following in mind when towing:

• Speed limits for towing a trailer vary by state or province. Do not exceed the posted towing speed limit.

• Lexus recommends that the vehicle-trailer speed limit is 65 mph (104 km/h) on a flat, straight, dry road. Do not exceed this limit, the posted towing speed limit or the speed limit for your trailer as set forth in your trailer owner’s manual, whichever is lowest. Instability of the towing vehicle-trailer combination (trailer sway) increases as speed increases.

Exceeding speed limits may cause loss of control.

• Before starting out, check the trailer lights, tires and the vehicle-trailer connections. Recheck after driving a short distance.

• Practice turning, stopping and reversing with the trailer attached in an area away from traffic until you become accustomed to the feel of the vehicle-trailer combination.

• Reversing with a trailer attached is difficult and requires practice. Grip the bottom of the steering wheel and move your hand to the left to move the trailer to the left. Move your hand to the right to move the trailer to the right. (This is generally opposite to reversing without a trailer attached.) Avoid sharp or prolonged turning. Have someone guide you when reversing to reduce the risk of an accident.

• As stopping distance is increased when towing a trailer, vehicle-to- vehicle distance should be increased. For each 10 mph (16 km/h) of speed, allow at least one vehicle and trailer length.

• Avoid sudden braking as you may skid, resulting in the trailer jackknif- ing and loss of vehicle control. This is especially true on wet or slippery surfaces.

• Avoid jerky starts or sudden acceleration.

• Avoid jerky steering and sharp turns, and slow down before making a turn.

• Note that when making a turn, the trailer wheels will be closer than the vehicle wheels to the inside of the turn. Compensate by making a wider than normal turning radius.

• Slow down before making a turn, in crosswinds, on wet or slippery sur- faces, etc.

Increasing vehicle speed can destabilize the trailer.

• Take care when passing other vehicles. Passing requires considerable distance. After passing a vehicle, do not forget the length of your trailer, and be sure you have plenty of room before changing lanes.

• To maintain engine braking efficiency and charging system perfor- mance when using engine braking, do not put the transmission in D.

Transmission shift range position must be in 5 in the S mode.

• Instability happens more frequently when descending steep or long downhill grades. Before descending, slow down and downshift. Do not make sudden downshifts while descending steep or long downhill grades.

• Avoid holding the brake pedal down too long or applying the brakes too frequently. This could cause the brakes to overheat and result in reduced braking efficiency.

• Due to the added load of the trailer, your vehicle’s engine may overheat on hot days (at temperatures over 85°F [30°C]) when driving up a long or steep grade. If the engine coolant temperature gauge indicates overheating, immediately turn off the air conditioning (if in use), pull your vehicle off the road and stop in a safe spot.

• Always place wheel blocks under both the vehicle’s and the trailer’s wheels when parking. Apply the parking brake firmly, and put the transmission in P. Avoid parking on a slope, but if unavoidable, do so only after performing the following:

Apply the brakes and keep them applied.

Have someone place wheel blocks under both the vehicle’s and trailer’s wheels.

When the wheel blocks are in place, release the brakes slowly until the blocks absorb the load.

Apply the parking brake firmly.

Shift into P and turn off the engine.

• When restarting after parking on a slope:

With the transmission in P, start the engine. Be sure to keep the brake pedal pressed.

Shift into 3, 2, L, or R (if reversing).

Release the parking brake and brake pedal, and slowly pull or back away from the wheel blocks. Stop and apply the brakes.

Have someone retrieve the blocks.

 - Matching trailer ball height to trailer coupler height

No matter which class of tow hitch applies, for a more safe trailer hookup, the trailer ball setup must be the proper height for the cou- pler on the trailer.

1. Trailer ball

2. Coupler

 - Before towing

Check that the following conditions are met:

• Ensure that your vehicle’s tires are properly inflated. • Trailer tires are inflated according to the trailer manufacturer’s recommenda- tion.

• All trailer lights work as required by law.

• All lights work each time you connect them.

• The trailer ball is set at the proper height for the coupler on the trailer.

• The trailer is level when it is hitched.

Do not drive if the trailer is not level, and check for improper tongue weight, overloading, worn suspension, or other possible causes.

• The trailer cargo is securely loaded.

• The rear view mirrors conform to all applicable federal, state/provincial or local regulations. If they do not, install rear view mirrors appropriate for towing pur- poses.

 - AVS (adaptive variable suspension system)

The suspension can be switched for improvement in driveability.

 - Break-in schedule

If your vehicle is new or equipped with any new power train components (such as an engine, transmission, differential or wheel bearing), Lexus recommends that you do not tow a trailer until the vehicle has been driven for over 500 miles (800 km).

After the vehicle has been driven for over 500 miles (800 km), you can start tow- ing. However, for the next 500 miles (800 km), drive the vehicle at a speed of less than 50 mph (80 km/h) when towing a trailer, and avoid full throttle acceleration.

 - Maintenance

• If you tow a trailer, your vehicle will require more frequent maintenance due to the additional load. (See “Owner’s Guide”, “Warranty and Services Guide”, “Owner’s Manual Supplement” or “Warranty Booklet”.) • Retighten the fixing bolts of the towing ball and bracket after approximately 600 miles (1000 km) of trailer towing.

 - If trailer sway occurs

One or more factors (crosswinds, passing vehicles, rough roads, etc.) can adversely affect handling of your vehicle and trailer, causing instability.

• If trailer swaying occurs:

• Firmly grip the steering wheel. Steer straight ahead.

Do not try to control trailer swaying by turning the steering wheel.

• Begin releasing the accelerator pedal immediately but very gradually to reduce speed.

Do not increase speed. Do not apply vehicle brakes.

If you make no extreme correction with the steering or brakes, your vehicle and trailer should stabilize.

• After the trailer swaying has stopped:

• Stop in a safe place. Get all occupants out of the vehicle.

• Check the tires of the vehicle and the trailer.

• Check the load in the trailer.

Make sure the load has not shifted.

Make sure the tongue weight is appropriate, if possible.

• Check the load in the vehicle.

Make sure the vehicle is not overloaded after occupants get in.

If you cannot find any problems, the speed at which trailer swaying occurred is beyond the limit of your particular vehicle-trailer combination.

Drive at a lower speed to prevent instability. Remember that swaying of the towing vehicle-trailer increases as speed increases.

CAUTION

Trailer towing precautions

• To tow a trailer safely, use extreme care and drive the vehicle in accordance with the trailer’s characteristics and operating conditions. Failure to do so could cause an accident resulting in death or serious injury. Vehicle stability and braking per- formance are affected by trailer stability, brake setting and performance, and the hitch. Your vehicle will handle differently when towing a trailer.

• Set the vehicle height to the LO mode and turn off the rear height control air sus- pension when you connect a trailer, otherwise the vehicle height may change due to the automatic leveling function, and you may catch part of your body in the vehicle, resulting in an accident.

CAUTION

To avoid accident or injury

• Do not exceed the TWR, unbraked TWR, GCWR, GVWR or GAWR.

• If the gross trailer weight is over 2000 lb. (907 kg), a sway control device with sufficient capacity is required.

• If the gross trailer weight is over 5000 lb. (2268 kg), a weight distributing hitch with sufficient capacity is required.

• Adjust the tongue weight within the appropriate range. Place heavier loads as close to the trailer axle as possible.

• Do not exceed 65 mph (104 km/h), the posted towing speed limit or the speed limit for your trailer as set forth in your trailer owner’s manual, whichever is lowest.

Slow down sufficiently before making a turn, in crosswinds, on wet or slippery surface, etc. to help avoid an accident. If you experience a vehicle-trailer instabil- ity from reducing a certain speed, slow down and make sure you keep your vehi- cle speed under the speed of which you experience the instability.

• Do not make jerky, abrupt or sharp turns.

• Do not apply the brakes suddenly as you may skid, resulting in jackknifing and loss of vehicle control. This is especially true on wet or slippery surfaces.

• Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle weight and trailer tongue weight capacities.

• Do not use cruise control when towing.

• Slow down and downshift before descending steep or long downhill grades. Do not make sudden downshifts while descending steep or long downhill grades.

• Vehicle-trailer instability is more likely on steep long down hills. Before descend- ing steep or long downhill grades, slow down and downshift. Do not make sudden downshifts when descending steep or long downhill grades. Avoid holding the brake pedal down too long or applying the brakes too frequently. This could cause the brakes to overheat and result in reduced braking efficiency.

CAUTION

 - Hitch

Trailer hitch assemblies have different weight capacities established by the hitch manufacturer. Even though the vehicle may be physically capable of towing a higher weight, the operator must determine the maximum weight rating of the par- ticular hitch assembly and never exceed the maximum weight rating specified for the trailer-hitch. Exceeding the maximum weight rating set by the trailer-hitch man- ufacturer can cause an accident resulting in death or serious personal injuries.

 - When towing a trailer

Lexus recommends trailers with brakes that conform to any applicable federal and state/provincial regulations.

• If the gross trailer weight exceeds unbraked TWR, trailer brakes are required.

Lexus recommends trailers with brakes that conform to all applicable federal and state/provincial regulations.

• Never tap into your vehicle’s hydraulic system, as this will lower the vehicle’s brak- ing effectiveness.

• Never tow a trailer without using a safety chain securely attached to both the trailer and the vehicle. If damage occurs to the coupling unit or hitch ball, there is danger of the trailer wandering into another lane.

NOTICE

 - When installing a trailer hitch

Use only the position recommended by your Lexus dealer. Do not install the trailer hitch on the bumper; this may cause body damage.

 - Do not directly splice trailer lights

Do not directly splice trailer lights. Directly splicing trailer lights may damage your vehicle’s electrical system and cause a malfunction.
