CAUTION
If any of the following conditions occurs, immediately
stop your vehicle at a safe place and contact your Lexus
dealer.
 The light does not turn off even after the parking
brake is released while the engine is running.
 The warning buzzer comes on together with the
warning light.
In either case, this can indicate that the brakes may not
work properly and your stopping distance will become
longer. Depress the brake pedal firmly and bring the
vehicle to an immediate stop.
 The brake system warning light remains on together
with the “ABS” warning light.
In this case, not only the antilock brake system will fail,
but also the vehicle will become extremely unstable
during braking.
Any of the following conditions may occur, but do not
indicate the malfunction:
 The light may stay on for about 60 seconds after the ignition
key is turned to the “ON” position. It is normal if it turns off
after a while.
 Depressing the brake pedal repeatedly may turn on the
warning light and buzzer. It is normal if the light turns off and
the buzzer stops sounding after a few seconds.
 You may hear a small sound in the engine compartment
after the engine is started or the brake pedal is depressed
repeatedly. This is a pump pulsating sound of the brake
system, and it is not a malfunction.
(b) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer act as a reminder to buckle up the driver’s
seat belt.
Once the ignition key is turned to “ON” or “START”, the
reminder light flashes and buzzer sounds if the driver’s seat
belt is not fastened. Unless the driver fastens the belt, the light
continues flashing and the buzzer stops after about 4 to 8
seconds.

(f) “ABS” Warning Light
The light comes on when the ignition key is turned to the “ON”
position. If the anti−lock brake system and the brake assist
system work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
When the “ABS” warning light is on (and the brake system
warning light is off), the following systems do not operate, but
the brake system still operates conventionally.
 Anti− lock brake system
 Brake assist system
 Active traction control system
 Vehicle stability control system
 Downhill assist control system
 Hill −start assist control
When the “ABS” warning light is on (and the brake system
warning light is off), the anti −lock brake system does not
operate, so that the wheels will lock up during a sudden braking
or braking on slippery road surfaces. If either of the following conditions occurs, this indicates
a malfunction somewhere in the components monitored
by the warning light system. Contact your Lexus dealer as
soon as possible to service the vehicle.

The light does not come on when the ignition key is turned
to the “ON” position, or remains on.
 The light comes on while you are driving.
A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If the “ABS” warning light remains on together with the
brake system warning light, immediately stop your
vehicle at a safe place and contact your Lexus dealer.
In this case, not only the antilock brake system will fail
but also the vehicle will become extremely unstable
during braking.
Either of the following conditions may occur, but do not
indicate a malfunction:
 The light may stay on for about 60 seconds after the ignition
key is turned to the “ON” position. It is normal if it turns off
after a while.
 Depressing the brake pedal repeatedly may turn on the
light. It is normal if it turns off after a few seconds.

9Front airbag sensors
10Airbag sensor assembly
The SRS front airbag system consists mainly of the above
components, and their locations are shown in the illustration.
The airbag sensor assembly consists of a safing sensor and
airbag sensor.
The airbag sensors constantly monitor the forward
deceleration of the vehicle. If an impact results in a forward
deceleration beyond the designed threshold level, the system
triggers the airbag inflators. At this time a chemical reaction in
the inflators very quickly fills the airbags with non− toxic gas to
help restrain the forward motion of the occupants. The front
airbags then quickly deflate, so that there is no obstruction of
the driver’s vision should it be necessary to continue driving. When the airbags inflate, they produce a loud noise and
release some smoke and residue along with non
−toxic gas.
This does not indicate a fire. This smoke may remain inside the
vehicle for some time, and may cause some minor irritation to
the eyes, skin or breathing. Be sure to wash off any residue as
soon as possible to prevent any potential skin irritation with
soap and water. If you safely exit from the vehicle, you should
do so immediately.
Deployment of the airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, primarily to the
head and chest, it may also cause other, less severe injuries
to the face, chest, arms and hands. These are usually in the
nature of minor burns or abrasions and swelling, but the force
of a deploying airbag can cause more serious injuries,
especially if an occupant’s hands, arms, chest or head are in
close proximity to the airbag module at the time of deployment.
This is why it is important for the occupant to: avoid placing any
object or part of the body between the occupant and the airbag
module; sit straight and well back into the seat; wear the
available seat belt properly; and sit as far as possible from the
airbag module, while still maintaining control of the vehicle.
Parts of the airbag module (steering wheel hub, airbag cover
and inflator) may be hot for several minutes after deployment,
so do not touch! The airbags inflate only once. The windshield
may be damaged by absorbing some of the force of the
inflating airbag.

STARTING AND DRIVING
371
(f) 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
be gradually lowered. When parking for a long time, 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 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.
(g) Rear height control failure warning
If there is a problem somewhere in the rear height control air
suspension, the “N” 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. If this is the case, bring your vehicle to your Lexus
dealer as soon as possible and have it checked.
ELECTRONIC MODULATED SUSPENSION
This electronic modulated suspension adjusts the
damping effect on the shock absorbers with the control
switch. Select one of the 4 modes which is suited to the
driving conditions with the control switch to provide good
riding comfort and stability.
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
