31X052a
: Blinking \f: Illuminating
When changing the vehicle height from the normal mode
to high:
1. The “N” (normal) mode indicator light goes off and the “HI”
(high) mode indicator light blinks.
2. After the vehicle height control reaches the high mode, the
high mode indicator light remains on.
With the active height control suspension turned off, if
you operate the height select switch or the vehicle height
is changing depending on the vehicle speed, the vehicle
height control enters the ready mode. In this case, the
height control indicator lights change as follows:
1. The present mode indicator light comes on and at the same
time the ready mode indicator light blinks.
2. When the active height control suspension is turned on, the
present mode indicator light goes off and the ready mode
indicator light blinks. (The vehicle height changes.) 3. After the vehicle height has changed completely, the
changed mode indicator light stays on.
If the vehicle is loaded heavily, the vehicle height cannot
be raised even if the height select switch is operated. If the
underbody of the vehicle has touched the surface on
bumpy roads, the vehicle height cannot be lowered with
the height select switch. The height control indicator
lights change as follows:
1. The present mode indicator light goes off and the selected
mode indicator light blinks.
2. The selected mode indicator light goes off. (The vehicle
height does not change.) The present mode indicator light
comes on again.
Height control “OFF” indicator light: When the ignition
switch is turned on, this light comes on. If it goes out after a few
seconds, the active height control suspension operates
correctly. If you push the height control switch, the active
height
control is turned off. The height control “OFF” indicator
light comes on.
In the following cases, there is a problem somewhere in your
active height control suspension. Although there is no problem
to continue normal driving, have the active height control
suspension checked by your Lexus dealer as soon as
possible.
 The height control “OFF” indicator light does not come on
when the ignition switch is turned on.
 The height control “OFF” indicator light blinks.

(g) Operation in cold weather
The active height control suspension does not operate in
cold weather when the suspension fluid temperature
drops below 30C (22F).
In this case, operating the height select switch does not
change the vehicle height. The vehicle height control enters
the ready mode and the selected height control indicator light
blinks. The active height control becomes operable if the
engine is warmed up with the suspension fluid temperature
being raised within normal operating limits. The vehicle
changes to the selected height when the vehicle height control
is in the ready mode.
When the suspension fluid temperature is around −30 C
(−22 F), the vehicle height cannot be raised even within the
available load capacity. After warming up the engine, push the
control switch on the “
” side once and then on the “ ” side
to select the desired vehicle height.
It takes longer to change the vehicle height when the
suspension fluid temperature drops below 15C (5F).
(h) Parking and stopping tips
If you immediately stop the engine to park the vehicle after
off−road driving, the vehicle height is lowered slightly as the
vehicle becomes cool. When parking, make sure there is
nothing that will be in contact with the underbody of the vehicle.
When you start the engine, the vehicle returns to the previous
height.
If you park the vehicle for a long time, the vehicle height may
gradually lower. When parking for a long time, make sure there
is nothing that will come in contact with the underbody of the
vehicle. When you start the engine, the vehicle returns to the
previous height.
If you stop the engine, the vehicle height may change in
accordance with the change in the temperature. When you
start the engine, the vehicle returns to the previous height.
(i) Installing or removing heavy equipment
If you install or remove heavy equipment exceeding 15 kg (33
lb.), the front torsion bar should be adjusted. Consult your
Lexus dealer.

(j) Active height control failure warning
If there is a problem somewhere in the active height control
suspension, the normal mode is automatically selected. If this
occurs, the height control “OFF” indicator light blinks and the
vehicle height control cannot be activated until the malfunction
is corrected.
Stop the engine and start it again. If the height control “OFF”
indicator light goes out, the active height control suspension
returns to normal. If the height control “OFF” indicator blinks
again, bring your vehicle to your Lexus dealer as soon as
possible and have it checked.
ADAPTIVE VARIABLE SUSPENSION (AVS)
This adaptive variable suspension adjusts the damping
effect on the shock absorbers with the damping mode
select switch. Select one of the 4 modes which is suited
to the driving conditions with the damping mode select
switch to provide good riding comfort and stability.
31X053c
 1For driving on a bumpy road
2For ordinary driving such as in the city traffic
3For moderate high speed driving
4For sporty type driving such as on winding
mountain roads and high speed driving
We recommend you to select the mode
2 for ordinary
driving. The damping effect will be changed automatically to
provide good riding comfort.

STARTING AND DRIVING
288When your vehicle is loaded heavily or you are driving in an
unpaved
road, the mode
3
or 4 will be recommended. To
provide good vehicle stability, the damping effect will be harder
than for ordinary driving mode.
With the four−wheel drive control lever at “L”, the damping
effect suitable for off −road driving will be provided.ACTIVE TRACTION CONTROL
SYSTEM
31X518a
Active traction control system indicator light
The active traction control system automatically helps
control the spinning of 4 wheels which may occur when
accelerating on slippery road surfaces, by controlling the
output of the brake and engine. Thus, the system assists
driver to control the driving power of 4 wheels. When you
turn the ignition switch on, the active traction control
system always turns on automatically, and the active
traction control indicator light will come on. The indicator
light will go off after a few seconds.
When active traction control is applied, the active traction
control system indicator light blinks.

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
291
The vehicle stability control system is activated when the
vehicle speed is about more than 15 km/h (9 mph).
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 vehicle stability control
is in the self−
check mode and does not indicate a malfunction.
31X529
Pushing the center differential lock button automatically turns
the vehicle stability control system off. At this time, the “VSC
OFF” indicator comes on with the center differential lock
indicator light. (For details, see “Four −wheel drive system” on
page 266.)

vehicle stability control system or active traction control
system.
If the “VSC/TRAC” warning light and “VSC OFF” indicator light
come on, have your vehicle checked by your Lexus dealer as
soon as possible. However, there is no problem even if the
“VSC/TRAC” warning light comes on when the brake actuator
temperature becomes high. (For details, see “Active traction
control system” on page 288.)
When the “ABS” warning light comes on, the vehicle stability
control system is not operating.
The lights will come on when the ignition key is turned to “ON”,
and will go off after a few seconds.
The lights may stay on for 60 seconds after the ignition key is
turned to the “ON” position. It is normal if they go off after a few
seconds.
