The driver monitor sensor detects the direction the driver is facing.

The system determines whether the driver is facing forward.

The pre-collision system is operational when

• Pre-collision seat belts (situation 1):

• Vehicle speed is greater than about 4 mph (5 km/h).

• The speed at which your vehicle is approaching the obstacle or the vehicle running ahead of you is greater than about 19 mph (30 km/h).

• The front occupants are wearing a seat belt.

• Pre-collision seat belts (situation 2):

• Vehicle speed greater than about 19 mph (30 km/h).

• The system detects sudden braking or skidding.

• The front occupants are wearing a seat belt.

• Pre-collision brake assist:

• Vehicle speed is greater than about 19 mph (30 km/h).

• The speed at which your vehicle is approaching the obstacle or the vehicle running ahead of you is greater than about 19 mph (30 km/h).

• The brake pedal is depressed.

• Pre-collision braking:

• The pre-collision braking off switch is not pressed.

• Vehicle speed is greater than about 10 mph (15 km/h).

• The speed at which your vehicle is approaching the obstacle or the vehicle running ahead of you is greater than about 10 mph (15 km/h).

• AVS (Adaptive Variable Suspension System) control (if equipped):

• Vehicle speed is greater than about 4 mph (5 km/h).

• The speed at which your vehicle is approaching the obstacle or the vehicle running ahead of you is greater than about 19 mph (30 km/h).

• Pre-collision alert braking (vehicle with driver monitor system):

• The pre-collision braking off switch is not pressed.

• The system determines that the driver is not facing forward.

• Vehicle speed is greater than about 10 mph (15 km/h).

• The speed at which your vehicle is approaching the vehicle running ahead of you is greater than about 25 mph (40 km/h).

Conditions that may trigger the system even if there is no possibility of a collision

• When there is an object by the roadside at the entrance to a curve

• When passing an oncoming vehicle on a curve

• When driving over a narrow iron bridge

• When there is a metal object on the road surface

• When driving on an uneven road surface

• When passing an oncoming vehicle on a left-turn

• When your vehicle rapidly closes on the vehicle in front

• When a grade separation/interchange, sign, billboard, or other structure appears to be directly in the vehicle’s line of travel

• When a billboard or other metallic structure appears to be in the direct line of travel due to driving on a hill.

• When there are excessive changes in the vehicle height (when it tilts forwards or backwards)

• When there is an abnormality in the radar sensor

• When passing through certain toll gates

• When driving on a bridge

When the system is activated in the situations described above, there is also a possi- bility that the seat belts will retract quickly and the brakes will be applied with a force greater than normal. When the seat belt is locked in the restricted position, stop the vehicle in a safe place, release the seat belt and refasten it.

Situations in which the pre-collision system does not function properly

The system may not function effectively in situations such as the following:

• On roads with sharp bends or uneven surfaces

• If a vehicle suddenly moves in front of your vehicle, such as at an intersection

• If a vehicle suddenly cuts in front of your vehicle, such as when overtaking

• In inclement weather such as heavy rain, fog, snow or sand storms

• When your vehicle is skidding with the VSC system off

• When an extreme change in vehicle height occurs

• When the axis of the radar is out of adjustment

Automatic cancelation of the pre-collision system

When a malfunction occurs due to sensor contaminations, etc. that results in the sensors being unable to detect obstacles, the pre-collision system will be automati- cally disabled. In this case, the system will not activate even if there is a collision pos- sibility.

Obstacles not detected

The system cannot detect plastic obstacles such as pylons. There may also be occa- sions when the system cannot detect pedestrians, animals, bicycles, motorcycles, trees, or snowdrifts.

When there is a malfunction in the system

Warning lights and/or warning messages will turn on or flash.

CAUTION

Limitations of the pre-collision system

Do not overly rely on the pre-collision system. Always drive safely, taking care to observe your surroundings and checking for any obstacles or other road hazards.

Failure to do so may cause an accident resulting in death or serious injury.

Cautions regarding the assist contents of the system

By means of alarms and brake control, the pre-collision system is intended to assist the driver in avoiding collisions through the process of LOOK-JUDGE-ACT. There are limits to the degree of assistance the system can provide, so please keep in mind the following important points.

Assisting the driver in watching the road

The pre-collision system is only able to detect obstacles directly in front of the vehicle, and only within a limited range. It is not a mechanism that allows careless or inattentive driving, and it is not a system that can assist the driver in low-visibil- ity conditions. It is still necessary for the driver to pay close attention to the vehi- cle’s surroundings.

Assisting the driver in making correct judgment

When attempting to estimate the possibility of a collision, the only data available to the pre-collision system is that from obstacles it has detected directly in front of the vehicle. Therefore, it is absolutely necessary for the driver to remain vigilant and to determine whether or not there is a possibility of collision in any given situ- ation.

Assisting the driver in taking action

The pre-collision system’s braking assist feature is designed to help reduce the severity of a collision, and so only acts when the system has judged that a collision is unavoidable. This system by itself is not capable of automatically avoiding a col- lision or bringing the vehicle to a stop safety. For this reason, when encountering a dangerous situation the driver must take direct and immediate action in order to ensure the safety of all involved.

CAUTION

When the sensor may not be correctly detecting the vehicle ahead

Apply the brakes as necessary in any of the following situations.

•  When water or snow thrown up by the surrounding vehicles hinders the function- ing of the sensor

•  When your vehicle is pointing upwards (caused by a heavy load in the luggage compartment etc.)

•  Vehicles that cut in suddenly

•  Vehicles with small rear ends (trailers with no load on board etc.)

•  Motorcycles traveling in the same lane

Handling the radar sensor

Observe the following to ensure the pre-collision system can function effectively:

• Keep the sensor and front grille cover clean at all times.

Clean the sensor and front grille cover with a soft cloth so you do not mark or damage them.

• Do not subject the sensor or surrounding area to a strong impact.

If the sensor moves even slightly off position, the system may become inaccurate or malfunction. If the sensor or surrounding area is subject to a strong impact, always have the area inspected and adjusted by your Lexus dealer.

• Do not disassemble the sensor.

• Do not attach accessories or stickers to the sensor, grille cover or surrounding area.

• Do not modify or paint the sensor and grille cover.

CAUTION

Handling the driver monitor sensor (vehicles with driver monitor sensor)

Observe the following to ensure the driver monitor sensor can function effectively.

Failure to do so may result in a malfunction or may prevent the system from cor- rectly determining the direction the driver is facing, resulting in an unexpected acci- dent.

• Do not disassemble, damage, lift or pull on the sensor.

• Do not touch the sensor while driving.

• Do not wet or spill water on the sensor.

• Do not drop anything on or allow anything to hit against the sensor. Do not sub- ject the sensor to an impact.

• Make sure that there are no scratches, dirt or stickers on the side of the sensor that faces the driver.

• Do not place any objects in front of the side of the sensor that faces the driver or cover the sensor.

Determining the direction the driver is facing (vehicles with driver monitor sensor)

The direction the driver is facing may not be determined correctly if the following conditions exist:

• There is an object between the driver monitor sensor and the driver’s face, such as when the sensor is blocked.

• A part of the driver’s face is covered.

• The sensor or the driver’s face is exposed to intense light such as sunlight.

• The driving posture is improper.

NOTICE

 - Precautions for cleaning the driver monitor sensor (vehicles with driver monitor sensor)

• Gently wipe the sensor with a soft cloth to prevent damage.

• Wipe any excess dirt with a cloth dampened with neutral detergent, all liquids having been wrung out of the cloth. After that, wipe again with a dry cloth.

• Do not use benzene, thinner, glass cleaners, wax, etc.
