◆Pre-crash warning
When a high possibility of a fron-
tal collision is detected, the pre-
crash safety system warning light
flashes, a buzzer sounds and a
message is shown on the multi-
information display to urge the
driver to take evasive action.
Pre-crash warning can be disabled
using the pre-crash braking off
switch.
◆Pre-crash seat belts (front seat 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. 48)
◆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.
PCS (Pre-Crash Safety system)
: If equipped
When the sensor detects that a frontal collision is highly likely or even
unavoidable, safety systems such as the brakes and seat belts are auto-
matically engaged to help avoid a collision or to lessen impact as well as
vehicle damage.

◆Pre-crash braking (if equipped)
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 sys-
tem determines that a collision is unavoidable, the brakes are automati-
cally applied to help avoid a collision or to reduce the collision speed.
When the vehicle is being stopped by pre-crash braking, the brake will
be engaged for a maximum of 2 seconds and then released automati-
cally. This pre-crash braking can be canceled by depressing the accel-
erator pedal or brake pedal.
Pre-crash braking can be disabled using the pre-crash braking off switch.
◆Suspension control
When there is a high possibility of a frontal collision, the operation of
suspension control helps prevent the front of the vehicle from dropping
when the brakes are applied suddenly.
◆Steering gear control (VGRS) (vehicles with camera sensors)
When the system determines that a collision is unavoidable, the steer-
ing gear ratio is changed to help improve the response to steering
input.
◆Driver monitor system (if equipped)
When the system determines that there is a possibility of a collision, and
either the driver is not facing forward or the driver’s eyes are closed,
pre-crash warnings are given in adva nce to warn the driver. If the sys-
tem determines that the conditions to operate pre-crash alert braking
have been met even when the possibility of a collision increases further,
pre-crash alert braking will operate.
Pre-crash alert braking can be disabled using the pre-crash braking off switch.

■Conditions that may trigger the system even if there is no danger of a collision
In any of the following situations where the frontal area of the radar sensor is inter-
rupted, the radar sensor may detect possibility of a frontal collision and the system
may be activated.
●When passing by an oncoming vehicle in a curve or a turn to the right or the left.
●When rapidly approaching an obstacle ahead (e.g. preceding vehicle, toll gate bar-
rier, etc.)
●When there is a structural object (billboard, low ceiling, fluorescent light, etc.)
above the uphill road ahead
●When driving on a narrow road or through under a low overhead structure (bridge,
tunnel, fly-under, etc.)
●When driving on an uneven road surface
●When there is a metal object, bump, or protrusion on the road surface
●When vehicle front part is raised or lowered depending on loading conditions
●When the direction of radar sensor is misaligned by strong impact applied on an
area around the radar sensor, etc.
●When there is an obstacle (guard rail, etc.) by the roadside at the entrance to a
curve
●When the front of your vehicle is pointing upwards (caused by putting a heavy load
in the trunk etc.)
●When driving through an area filled with steam or smoke
When the system is activated in the situatio ns described above, there is also a possi-
bility that the seat belts will retract quickly and the brakes may 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 it.
■Obstacles not detected
The radar sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the sensor cannot detect pedestrians, animals, bicycles,
motorcycles, trees, or snowdrifts.
■A camera sensor cannot detect obstacles in the following situations:
●A camera sensor is directly receiving intense light, such as sunlight.
●Visibility is poor because of bad weather or other reasons.
●The sensor temperature is extremely high.
●The headlights are not turned on in darkness such as at night or in a tunnel.

CAUTION
■Limitations of the pre-crash safety system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Do not use the pre-crash safety system instead of normal braking operations under
any circumstances. This system will not prevent collisions or lessen damage or inju-
ries in all cases. Do not overly rely on this system. Failure to do so may cause an
accident, resulting in death or serious injury.
This system has been designed to help avoid and reduce the impact of collisions.
However, the system operates differently depending on the situation ( P. 372,
374). As a result, the same level of performance may not be expected in all cases.
Also, the pre-crash safety brakes may not operate if the driver is depressing the
brake pedal or turning the steering wheel, as the system will determine such condi-
tions as collision avoidance operations.
■Handling the radar sensor
Observe the following to ensure the pre-crash safety system can function effec-
tively. Otherwise, the system may not function correctly and could result in an acci-
dent.
●Keep the sensor and grille cover clean at all times.
Clean the sensor and 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 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.
●If the radar sensor needs to be replaced, contact your Lexus dealer.
4004-6. Driving tips
LS460/LS460L_GE (OM50G06E)
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away the
water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan, remove
any snow that has accumulated on the air inlet vents in front of the wind-
shield.
●Check for and remove any excess ice or snow that may have accumu-
lated on the exterior lights, vehicle’s roof, chassis, around the tires or on
the brakes.
●Remove any snow or mud from the bottom of your shoes before getting
in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and the
vehicle ahead, and drive at a reduced speed suitable to road conditions.
●Park the vehicle and move the shift lever to P without setting the park-
ing brake. The parking brake may free ze up, preventing it from being
released. If the vehicle is parked without setting the parking brake,
make sure to block the wheels.
Failure to do so may be dangerous because it may cause the vehicle to
move unexpectedly, possibly leading to an accident.
●If the vehicle is parked without setting the parking brake, confirm that
the shift lever cannot be moved out of P*.
*: The shift lever will be locked if it is attempted to be shifted from P to any other
position without depressing the brake pedal. If the shift lever can be shifted
from P, there may be a problem with the shift lock system. Have the vehicle
inspected by your Lexus dealer immediately.
