or equivalent tool.
To prevent damage to the cover, cover the tip
of the screwdri ver with a rag.
Press the shift lock override button.
The shift lever can be shifted while the button
is pressed.
WARNING
■When driving on slippery road surfaces
Be careful of downshifting an d sudden acceleration, as this could result in the vehicle skidding to the side or spinning.
■To prevent an accident wh en releasing the shift lock
Before pressing the shift lock override button, make sure to set the parking brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of the brake pedal when the
shift lock override button is pressed and the shift lever is shifted out of P, the vehicle may suddenly start, possibly leading to an a ccident resulting in death or serious injury.

■Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield is subject to vibratio n in AUTO mode. Take care that your fingers or anything
else do not become caught in the windshield wipers.
■Caution regarding the use of washer fluid

◆Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a warn-
ing message will be displayed on the
multi-information display to urge the
driver to take evasive action.
◆Pre-collision brake assist
When the system determines that the po ssibility of a frontal collision is high,
the system applies greater braking force in relation to how strongly the brake
pedal is depressed.
PCS (Pre-Collision System)
: If equipped
The pre-collision system uses a rada r sensor and camera sensor to detect
vehicles and pedestrians*1 in front of your vehicle. When the system deter-
mines that the possibility of a frontal collision with a vehicle or pedestrian is
high, a warning operates to urge the driver to take evasive action and the
potential brake pressure is increased to help the driver avoid the collision. If
the system determines that the possibility of a frontal collision with a vehicle or
pedestrian is extremely high, the brakes are automatically applied*2 to help
avoid the collision or help reduce the impact of the collision.
The pre-collision system can be disabl ed/enabled and the warning timing can
be changed. ( P. 269)
*1: Depending on the region in which the vehicle was sold, the pedestrian detection
function may not be available. Contact any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer for details.
*2: Depending on the region in which the ve hicle was sold, the pre-collision braking
function (automatic braking function) may not be available. Contact any authorized
Lexus retailer or Lexus authorized repair er, or any reliable repairer for details.
