LS460/LS460L_GE (OM50G06E)
The vehicle height is maintained at the selected level regardless of the
number of occupants and luggage weight.
Turns high mode on/off.
When on, the “HEIGHT HIGH” indi-
cator will come on.
■Operating sound of the air suspension compressor
When the vehicle height is lowered, such as when entering or loading the vehicle, or
high mode is selected, the compressor may operate and a whirring sound may be
heard. This does not indicate a malfunction.
Electronically modul ated air suspension
: If equipped
By independently controlling the damping force of the shock absorbers
for each of the 4 wheels according to the road and driving conditions
and the selected driving mode, this system achieves ride comfort with
superior steering stability, an d ensures good vehicle posture.
In addition, vehicle height can be se lected according to road and driv-
ing conditions.

CAUTION
■Be sure to stop the engine in the following situations in order to stop operation of
the electronically modulated air suspension:
●The vehicle is parked on a curb.
●Any of the wheels is stuck in a ditch.
●It is necessary to jack up the vehicle.
●It is necessary to tow the vehicle with part of it lifted.
If the engine switch remains in IGNITION ON mode, the vehicle height may
change, and you may catch part of your body in the vehicle, resulting in accidental
damage.

◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driv ing on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
◆TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
◆Hill-start assist control
Helps to prevent the vehicle from rolling backward when starting on an
incline or slippery slope
Driving assist systems
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be
aware, however, that these system s are supplementary and should not
be relied upon too heavily when operating the vehicle.

◆VGRS (Variable Gear Ratio Steering) (if equipped)
Adjusts the wheel turning angle in accordance with the vehicle speed
and steering wheel movement
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
◆VDIM (Vehicle Dynamics Integrated Management)
Provides integrated control of the ABS, brake assist, TRC, VSC, hill-
start assist control, EPS and VGRS (if equipped) systems
Helps to maintain vehicle stability when swerving on slippery road sur-
faces by controlling the brakes, engine output, steering assist, and if
equipped with VGRS, steering ratio
◆PCS (Pre-Crash Safety system) (if equipped)

◆Emergency brake signal (if equipped)
When the brakes are applied suddenly, the stop lights automatically
flash to alert the vehicle behind

The slip indicator light will flash
while the TRC/VSC/ABS/hill-start
assist control systems are operating.
The stop lights and high mounted
stoplight turn on when the hill-start
assist control system is operating.
If the vehicle gets stuck in fresh snow or mud, the TRC and VSC systems
may reduce power from the engine to the wheels. Pressing VSC OFF
switch to turn the system off may make it easier for you to rock the vehicle
in order to free it.
■Turning off the TRC system only
To turn the TRC system off,
quickly press and release the
switch.
The “TRC OFF” will be shown on
the multi-information display. Press
the switch again to turn the system
back on.

■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.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be heard.
This does not indicate a malfunction.

■Reactivation of the TRC/VSC systems
Even after the TRC/VSC systems have been turned off, turning the engine off and
then on again will automatically reactivate the TRC/VSC systems.
■Reactivation of the TRC system linked to vehicle speed
When only the TRC system is turned off, the TRC system will turn on when vehicle
speed increases. However, when both TRC and VSC systems are turned off, the sys-
tems will not turn on even when vehicle speed increases.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from overheat-
ing when there is frequent steering input over an extended period of time. The steer-
ing wheel may feel heavy as a result.* Should this occur, refrain from excessive
steering input or stop the vehicle and turn the engine off. The EPS system should
return to normal within 10 minutes.
*: If the LKA (Lane-Keeping Assist) system cannot operate in this case, a warning
message will be shown on the multi-information display.
■Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal will oper-
ate:
●The emergency flashers are off.
●Actual vehicle speed is over 55 km/h (35 mph).
●The brake pedal is depressed in a manner that cause the system to judge from the
vehicle deceleration that this is a sudden braking operation.
■Automatic system cancelation of emergency brake signal (if equipped)
The emergency brake signal will turn o ff in any of the following situations:
●The emergency flashers are turned on.
●The brake pedal is released.
●The system judges from the vehicle deceleration that is not a sudden braking oper-
ation.

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 recommended tire
inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the
driving assist systems, and may cause a system to malfunction.
