PCS (Pre-Collision System)
: If equipped
When the system detects the possibilit y of a frontal collision, the systems
such as the brakes and seat belts are automatically engaged to lessen
impact and injuries to occupant s as well as vehicle damage.
■Pre-collision seat belts (front seat belts only)
If the system detects that a collisio n is unavoidable, the system will
retract the seat belt be fore the collision occurs. 
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. ( P. 8 8 )
However, when the VSC system is disabled, the system will not
operate in the event of skidding.
■ Pre-collision brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in rela tion to how strongly the brake
pedal is depressed.
■ Pre-collision 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-collision
braking can be disabled using th e pre-collision braking off switch.

Disabling pre-collision brakingPre-collision braking disabled
Pre-collision braking enabled
The “PCS” warning light comes on
when pre-
collision braking is dis-
abled.
■ AVS (Adaptive Variable Suspension System) control (if equipped)
When the system determines that there is a high possibility of a colli-
sion, the AVS optimizes the damping effect ( P. 316)
■ Driver monitor system (if equipped)
When the system determines that there is a possibility of a collision,
and the driver is not facing forwar d, PCS warnings are given in
advance to warn the driver. If the driver continues to be not facing
forward, and a probable collisio n is detected, PCS informs the
driver of danger by performing slig ht braking to provide a physically
warning (pre-collision alert braking). ( P. 340)

■The pre-collision system is operational when
●Pre-collision warning
• Vehicle speed is greater than about 9 mph (15 km/h).
• The speed at which your vehicle is approaching the obstacle or oncoming vehicle is greater than about 9 mph (15 km/h).
●Pre-collision seat belts (linked to the radar sensor):
• Vehicle speed is greater than about 3 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or oncoming vehicle is greater than about 18 mph (30 km/h).
• The front occupants are wearing a seat belt.
●Pre-collision seat belts (linked to brake operation):
• Vehicle speed greater than about 18 mph (30 km/h).
• The system detects sudd en braking or skidding.
• The front occupants are wearing a seat belt.
●Pre-collision brake assist:
• Vehicle speed is greater than about 18 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle running ahead of you is greate r than about 18 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 9 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 9 mph (15 km/h).
●AVS (Adaptive Variable Suspension System) control (if equipped):

■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 mess ages will turn on or flash. (P. 6 8 6 , 6 9 8 )

CAUTION
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents. 
Failure to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being used,
or 30 mph (50 km/h), whichever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden turns and braking, as use of chains may adversely affect vehicle
handling.
●Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tire s from Lexus dealers or legitimate tire
retailers. 
This is because the removal and attachment of snow tires affects the operation of
the tire pressure warning valves and transmitters.
■Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly when
tire chains are fitted.
