Do not adjust the display while the vehicle is moving.
Be sure to adjust the display only when the vehicle is
stopped.
CALIBRATING THE COMPASS (circling calibration)
16x280a
“C” appears on the display in case the circling calibration is
required due to a drastic change in the magnetic field. To
rectify this, follow the calibration procedure below.
16x270
Drive the vehicle slowly (at 8 km/h (5 mph) or lower) in a circle
until the direction is displayed. If there is not enough space to
drive in a circle, drive around the block until the direction is
displayed.
After driving in 1 to 3 circles in the above method, calibration
is complete with the direction shown on the display.
If calibration cannot be performed because of the magnetized
vehicle, etc., take your vehicle to Lexus dealer.
 Do not perform circling calibration of the compass in a place
where the earth’s magnetic field is subject to interference by
artificial magnetic fields (underground parking, under a
steel tower, between buildings, roof parking, near a
crossing, near a large vehicle, etc.).
 During calibration, do not operate electric systems (moon
roof, power windows, etc.) as they may interfere with the
calibration.

AUDIO

(i) If the player malfunctions
If the player or another unit equipped with the player
malfunctions,
your audio system will display the following error
messages.
If “WAIT” appears on the display: It indicates that the inside
of the player unit may be too hot due to the very high ambient
temperature. Remove the CD from the player and allow the
player to cool down.
If “ERROR 1” appears on the display: It indicates that the
CD is dirty, damaged, or it was inserted upside down. Clean
the CD or insert it correctly.
If “ERROR 3” or “ERROR 4” appears on the display: It

ACTIVE HEIGHT CONTROLSUSPENSION (AHC)
This active height control suspension controls the vehicle
height depending on the vehicle driving condition. Select
your desired height among the “HI” (high), “N” (normal)
and “LO” (low) modes with the height select switch.
31X600
(a) Vehicle height modes
 “HI” (high) mode
The vehicle height is about 40 mm (1.6 in.) higher at front
and about 50 mm (2.0 in.) higher at rear than the normal
mode height.
This mode is suitable when driving on bumpy roads and
through water.
This mode is available when the vehicle speed is under about
30 km/h (19 mph).
CAUTION
The “HI” (high) or “Extra high” mode should be used for
severe offroad driving condition only. Because the
vehicle’s center of gravity is higher in this setting, the
vehicle may become unstable when turning abruptly,
resulting in an accident.
When the four −wheel drive control lever is put at “L”, this mode
may change to the extra high mode automatically in
accordance with the driving condition.
When the vehicle exceeds the specified vehicle speed, the
vehicle height changes to the following:
With the fourwheel drive control lever at “H” and at the
vehicle speed of 30 km/h (19 mph) or over, the normal mode
is automatically selected.
With the fourwheel drive control lever at “L” and at the
vehicle speed of 50 km/h (30 mph) or over, the vehicle
height becomes automatically about 25 mm (1.0 in.) higher
than the normal mode height. If the vehicle speed is lowered
about 20 km/h (12 mph) or le ss after that, the high mode
automatically resumes.
Extra high mode
This mode is automatically selected from the high mode
with the fourwheel drive control lever placed in “L”
position depending on the vehicle driving condition.
If the vehicle becomes stuck, the vehicle height rises
automatically to the extra high mode (slightly higher or at about
70 mm (2.8 in.) higher than normal mode height).

STARTING AND DRIVING
280In the following cases, the extra high mode changes to the high
mode automatically:

When your vehicle is no longer stuck.
 When the four −wheel drive control lever is put in a position
other than “L”.
When you push the height select switch on the “
” side
in the extra high mode, the normal mode is selected.
Since the extra high mode is automatically selected, you
cannot select this mode on purpose with the height select
switch.
 “N” (normal) mode
The vehicle height in this mode is standard.
This mode is suitable for ordinary driving.
 “LO” (low) mode
The vehicle height is about 50 mm (2.0 in.) lower at front
and about 40 mm (1.6 in.) lower at rear than the normal
mode height.
This mode allows you easy access to the vehicle (getting in
and out) and easy loading and unloading operation.
This mode is available when the vehicle is stopped. When you
start the vehicle, the normal mode is automatically selected.
NOTICE
The normal mode is automatically selected when the
vehicle begins to move in the low mode. So be careful
when you drive in any place where the overhead height
is limited.
(b) Automatic leveling function
Regardless of the number of occupants or the luggage
loading condition, the vehicle height is always
automatically adjusted to a fixed height in any mode.
However, the vehicle height cannot be raised if the vehicle load
exceeds the limits. (See page 281.)
(c) Vehicle height mode changing condition
To change the vehicle height, it is necessary to meet the
following 3 conditions.
 The engine should be running.
 All the side doors and back door should be closed.
 The height control “OFF” indicator light should go off.
When selecting a mode with the four −wheel drive control lever
at “H”, there is a vehicle speed limit. Refer to the following
table.

In the following cases the active height control
suspension does not operate even if the above conditions
are all met.
 The brake pedal has been depressed for longer than about
5 seconds with the vehicle stopped.
 The suspension fluid temperature is lower than −30 C
(−22 F). If the engine is warmed up, the suspension fluid
temperature will be raised as the inside of the engine
compartment becomes warmer. Then the active height
control suspension becomes operable.
 Driving on bumpy roads, which may cause the suspension
to fully elongate.
 The steering wheel is operated abruptly more than 3/4 turn

The height control indicator light indicates which mode is
selected. (See page 284.)
NOTICE
 If you change the vehicle height frequently, the pump
may overheat. To prevent this, the active height
control suspension should be stopped temporarily
for a minute between selections. Operate it again.

STARTING AND DRIVING
289
You may hear a sound in the engine compartment for a few
seconds when the engine is started or just after the vehicle
begins to move. This means that the active traction control
system is in the self
−check mode, and does not indicate
malfunction. When the active traction control system is
operating, you may feel vibration or hear noise of your vehicle,
caused by operation of the brakes. This indicates the system
is functioning properly.
When getting the vehicle out of mud or newly fallen snow, etc.,
the active traction control system will help operate to prevent
the wheels from spinning.
31X503
 Active traction control system failure warning
This light warns when there is a problem somewhere in the
active traction control system or vehicle stability control
system.
If the “VSC/TRAC” warning light comes on, have your vehicle
checked by your Lexus dealer as soon as possible. The brake actuator temperature increases during the active
traction control system or vehicle stability control system
operating. If the brake actuator temperature becomes too high
while the active traction cont
rol system or vehicle stability
control system is operating, a buzzer will start to sound
intermittently to indicate that the active traction control system
can no longer operate. In this case, immediately stop your
vehicle at a safe place. If the system continues to operate, the
buzzer sound changes from intermittent to continuous. (The
continuous buzzer sound will stop after about 3 seconds.) At
the time the “VSC/TRAC” warning light will come on and the
active traction control system temporarily stops operating in
order to protect the brake actuator. (Although the active
traction control system does not operate, there is no problem
to continue your driving.) The system will be automatically
restored after a short time and “VSC/TRAC” warning light goes
off if the accelerator pedal is released.
When the “ABS” warning light comes on, the active traction
control system is not operating.
The “VSC/TRAC” warning light will come on when the ignition
key is turned to “ON”, and will go off after a few seconds.
The “VSC/TRAC” warning light may stay on for 60 seconds
after the ignition key is turned to the “ON” position. It is normal
if it goes off after a few seconds.
Depressing the brake pedal repeatedly may turn on the
“VSC/TRAC” warning light. It is normal if it goes off after a few
seconds.
When the “VSC/TRAC” warning light comes on, the active
traction control system is not operating, but there is no problem
if you continue to drive.

STARTING AND DRIVING
293
VARIABLE GEAR RATIO STEERINGSYSTEM
The variable gear ratio steering system adjusts the wheel
turning angle depending on the vehicle speed and how
much you turn the steering wheel.
The vehicle wheel turning angle will be changed with a smaller
degree of wheel maneuvering when you are driving at very low
speed such as when putting your vehicle into a garage.
In the following cases, to prevent the system from overheating,
the system could be temporarily deactivated with the change
in the center position of the steering wheel. This is not a
malfunction. After the cause of the problem is eliminated, the
system will return to normal automatically after a few minutes.
 If you continue maneuvering the steering wheel when the
vehicle is stopped or running at very low speed
 If you continue driving holding the steering wheel to the
extreme right or left
 If you maneuver the steering wheel immediately after
starting the engine at less than about −30C (− 22F) While the system is not functioning, a larger degree of wheel
maneuvering is needed during driving at low speed. If the
center position of the steering wheel is changed frequently,
have your vehicle inspected at your Lexus dealer.
CAUTION
Take due care especially when driving at low speed as
the vehicle changes direction in greater proportion to
the steering wheel maneuvering.
NOTICE
Do not disconnect the battery with the steering wheel
turned, or the center position of the steering wheel
could be slightly and temporarily changed. However,
after driving for a short while, the system will return to
normal
and the center position of the steering wheel will
be in the appropriate position.
The light will flash if you disconnect and reconnect the battery
terminal. This is because the system is reset temporarily.
However, it is no problem to drive. To turn off the light, drive for
a short while. The system will be set automatically and return
to normal.

Variable gear ratio steering system failure
warning
31x500b
This light warns that there is a problem somewhere in the
variable gear ratio steering system.
The light will come on when the ignition key is turned to “ON”
and will go off after a few seconds.
If the light comes on while driving, the system is not working.
Although conventional steering operates when maneuvered,
a larger degree of wheel maneuvering (than at the time when
the system is functioning properly) is needed when driving at
low speed. At this time, the center position of the steering
wheel could be changed. Although it is no problem to continue
driving, have your vehicle repaired at your Lexus dealer. In the following cases, contact your Lexus dealer.

The warning light does not come on after the ignition key is
turned to “ON”.
 The warning light remains on after the ignition key is turned
to “ON”.
 The warning light comes on while driving.
