2884-3. Operating the lights and wipers
LS460/LS460L_GE (OM50G06E)
AFS (Adaptive Front-lighting System) secures excellent visibility at inter-
sections and on curves by automatically adjusting the direction of the light
axis of the headlights according to vehicle speed and the degree of the
tire’s angle as controlled by steering input.
AFS operates at speeds of 10 km/h (6 mph) or higher.
■Daytime running light system
To make your vehicle more visible to othe r drivers during daytime driving, the day-
time running lights turn on automatically whenever the engine is started and the
parking brake is released with the headlight switch off or in the position. (Illumi-
nate brighter than the front position ligh ts.) Daytime running lights are not designed
for use at night.
■Headlight control sensor
AFS (Adaptive Front-lighting System)
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

■When the message is displayed on the multi-information display showing that TRC
has been disabled even if the VSC OFF switch has not been pressed
TRC and hill-start assist control cannot be operated. Contact your Lexus dealer.
■Hill-start assist control is operational when
●The system has detected that the vehicle is moving backward.
●Vehicles without paddle shift switches: The shift lever is in the D or S position.
Vehicles with paddle shift switches: The shift lever is in the D or M position.
●The brake pedal is not depressed.
■VGRS is disabled when
VGRS may stop operating in the following situations.
In this event, the steering wheel may move from its straight forward position, but it
will return when the system restarts.
●When the steering wheel is operated for an extended period of time while the vehi-
cle is stopped or is moving very slowly
●When the steering wheel has been held fully to the left or right
●When the battery is low or the voltage temporarily drops
The center position of the steering wheel may change when VGRS is disabled. How-
ever, the position will return to normal after VGRS is reactivated.
■Sounds and vibrations caused by the ABS, brake assist, TRC, VSC, hill-start assist
control and VGRS systems
●A sound may be heard from the engine compartment when the brake pedal is
depressed repeatedly, when the engine is started or just after the vehicle begins to
move. This sound does not indicate that a malfunction has occurred in any of these
systems.
●Any of the following conditions may occur when the above systems are operating.
None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
●The steering wheel may be moved slightly or a sound may be heard when the
engine is started or stopped. None of these indicate that a malfunction has
occurred.

This does not indicate a malfunction.

3684-5. Using the driving support systems
LS460/LS460L_GE (OM50G06E)
◆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.
