CAUTION
If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS airbag warning light
not come on when you start the hybrid system, this could mean that these
systems are not available to help protect you in an accident, which could
result in death or serious injury. Have the vehicle inspected by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional immediately if this occurs.
Warning lights
Warning lights inform the driver of malfunctions in any of the
vehicle’s systems. (P. 571)
*1: These lights turn on when the “POWER” switch is turned to ON
mode to indicate that a system check is being performed. They
will turn off after the hybrid system is on, or after a few seconds.
There may be a malfunction in a system if a light does not come
on, or if the lights do not turn off. Have the vehicle inspected by
any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional.

PCS (Pre-Crash Safety system)
: If equipped
When the radar sensor detects possibility of a frontal collision, the pre-
crash safety system such as the brakes and seat belts are automatically
engaged to lessen impact as well as vehicle damage.
Pre-crash seat belts (front seat belts only)
If the pre-crash sensor detects that a collision is unavoidable, the
pre-crash safety system will retract the seat belt before the collision
occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. (P. 1 1 0 )
However, when the VSC system is disabled, the system will not
operate in the event of skidding.
Pre-crash brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in relation to how strongly the brake
pedal is depressed.
Pre-crash braking
When there is a high possibility of a frontal collision, the system
warns the driver using a warning light, warning display and buzzer.
If the system determines that a collision is unavoidable, the brakes
are automatically applied to reduce the collision speed. Pre-crash

Disabling pre-crash braking
Pre-crash braking disabled
Pre-crash braking enabled
The “PCS” warning light will
turn on when pre-crash brak-
ing is disabled.
Radar sensor
The radar sensor detects vehi-
cles or other obstacles on or
near the road ahead and deter-
mines whether a collision is
imminent based on the position,
speed, and heading of the obsta-
cles.

Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the sensor cannot detect pedestrians, animals, bicy-
cles, motorcycles, trees, or snowdrifts.
When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (P. 571,
578)
Situations in which the pre-crash safety 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 vehicle, such as at an intersection
If a vehicle suddenly cuts in front of 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-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-crash safety system will
be automatically disabled. In this case, the system will not activate even if
there is a collision possibility.
