CAUTION
Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
appropriate tire pressure level.
The ABS, VSC and TRC systems will not function correctly if different
tires are fitted on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional, for further information when replacing tires or
wheels.
Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will
affect the driving assist systems, and may cause the system to malfunction.

PCS (Pre-Crash Safety system)
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 and injuries to occupants as well as vehicle
damage.
Pre-crash seat belts
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. 7 6 )
However, the system will not operate in the event of skidding when
the VSC systems are disabled.
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. The pre-

Disabling the pre-crash braking
The pre-crash braking function
can be turned on and off using
the satellite switch. (P. 365)
Press “”or “” to display the
PCS brake setting ( ). Then,
press the “ON/OFF” button in
the middle of the switch to
select either “ON” or “OFF”
().
It may take approximately 3
seconds for the display to
change after the satellite switch
is operated.
The “PCS” warning light
flashes when “OFF” is selected.
Radar sensor
Detects vehicles or other obsta-
cles on or near the road ahead
and determines whether a colli-
sion is imminent based on the
position, speed, and heading of
the obstacles.

Obstacles not detected
The sensor cannot detect plastic obstacles such as pylons. There may also be
occasions when the radar sensor cannot detect pedestrians, animals, bicy-
cles, motorcycles, trees, or snowdrifts.

The pre-crash safety system is operational when
Pre-crash seat belts (type A):
• Vehicle speed is above 5 km/h (4 mph).
• The speed at which your vehicle is approaching the obstacle or oncom-
ing vehicle exceeds 30 to 40 km/h (19 to 25 mph).
• The front occupants are wearing a seat belt.
Pre-crash seat belts (type B):
• Vehicle speed exceeds 30 km/h (19 mph).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
Pre-crash brake assist:
• Vehicle speed is above 30 km/h (19 mph).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than 30 to 40 km/h (19 to 25
mph).
• The brake pedal is depressed.
Pre-crash braking:
• The pre-crash braking function is activated.
• Vehicle speed is above 15 km/h (10 mph).
• The relative speed difference between your vehicle and another vehi-
cle that is forward of your vehicle, or the speed at which your vehicle
is approaching an obstacle is greater than 15 km/h (10 mph).
Conditions that may trigger the system even if there is no possibility of col-
lision
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 right-turn (right-hand drive
countries) or left-turn (left-hand drive countries)
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 vehi-
cle’s direct line of travel due to driving on a hill.
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
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
possibility 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
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten.
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 your vehicle, such as at an inter-
section
If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
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.
