Side airbags
Side airbags:
In response to a severe side impact, the side airbag for the driver
or front passenger works together with the seat belt to help
preventing or reducing injury by inflating, in order to decrease
the impact mainly on the driver or front passenger’s chest.
The side airbag on the passenger seat is activated even with no
passenger in the front seat.
Be sure to wear your seat belt.
CAUTION
SRS side airbags inflate with considerable force. To avoid
potential death or serious injury during inflation of a side
airbag, Lexus strongly recommends that the driver and front
passenger;
Wear their seat belt.
Remain properly seated with their back against the seat at
all times.
16L136-2
The indicator comes on when the ignition key is turned to the
”ACC” or ”ON” position. It goes off after about 6 seconds. This
means the SRS is operating properly.
The SRS warning light system monitors the airbag sensor
assemblies, inflators, seat belt pretensioners, warning light,
interconnecting wiring and power sources.

Driver and front passenger airbag sensor assembly
The SRS airbag sensor assemblies consist of a safing sensor and
driver and front passenger airbag sensor.
In a severe frontal impact, the driver and front passenger airbag
sensor detects deceleration and the system triggers the front airbag
inflators and seat belt pretensioners. In a severe side impact, the side
airbag sensor triggers the side airbag inflator. Then a chemical
reaction in the inflators momentarily fills the airbags with nontoxic
gas to help restrain the forward or lateral motion of the occupants.
Then the inflators fill the airbags and the seat belts are quickly drawn
back in by the retractors to help restrain forward motion of the
occupants.
When the SRS operates, it produces a fairly loud noise and release

ELECTRONICALLY MODULATED
AIR SUSPENSION
(U.S.A. ONLY)
This electronically modulated air suspension adjusts the
damping effect on the shock absorbers and the vehicle height.
This adjustment is automatically made in response to the driving
conditions to provide good riding comfort and stability in all
driving conditions.
(a) Vehicle height adjustment
31L015-3
This system maintains a stable vehicle height, regardless of
occupants and luggage weight. You can select one of the
following modes using a selector switch.

STARTING AND DRIVING
172”NORMAL” mode For driving on roads with a normal surface.
”HIGH” mode For driving on rough roads which are unsurfaced
or continually bumpy.
The damping effect is set slightly firmer in ”HIGH” mode. So you
may feel the vibration of the vehicle compared to in ”NORMAL”
mode. However, this does not mean a malfunction in the system. We
recommend you use a ”NORMAL” mode in normal driving.
To change the mode, push the selector switch.
”NORMAL” mode
The vehicle height remains at normal height at all driving speeds.
”HIGH” mode
The vehicle height switches between the following two vehicle
heights according to the driving conditions:
Vehicle height
Driving condition
NormalMedium and high speed driving
HighLow speed driving
31L016-2
The indicator light shows ”HIGH” mode is selected.
When you turn the ignition key to the ”ON” position, the indicator
light will come on for 2 seconds in any mode.
NOTICE
For vehicles equipped with the height control switch, be sure to
turn the ignition switch off before jacking. If this is not done, the
vehicle height adjustment function will operate, which may
cause body damage.
(b) Malfunction warning
If the ”HI” indicator light blinks, there is a malfunction in this
system. Have the system checked by your Lexus dealer at the first
opportunity.

Vehicle skid control failure warning
31L073
In the following cases, the warning message appears and the
reminder light next to the warning message and the ”VSC OFF”
indicator light come on. And the warning tone also sounds.
(a) After the removal of the battery terminals (See ”Initial
adjustment of vehicle skid control system” described below.)
(b) If the vehicle skid control system malfunctions
If the message appears for the cause of (b), have your vehicle
checked by Lexus dealer as soon as possible.
Although the message appears, there is no problem to continue your
normal driving.
Initial adjustment of vehicle skid control system
After the battery terminals are disconnected, an initial adjustment
should be made. At this time, the reminder light comes on and the
warning message appears in the multi information display.
Make an initial adjustment in the following ways:
1. Apply the parking brake and put the transmission in ”P”.
2. Connect the battery terminals.
3. Turn the ignition switch on. At this time, the ”VSC OFF”
indicator light comes on and then about 6 seconds later, the reminder
light comes on and the ”CHECK VSC” warning message appears in
the multi information display.
4. The warning message and the ”VSC OFF” indicator light go out
about 15 seconds after the ignition switch is turned on. If the vehicle
is shaken after the ignition switch is turned to ”ON”, it may take
longer to go out the warning message.
If the warning message does not go out about 1 minute after you turn
the ignition switch on, turn it off and then on again.
If the vehicle is on the moving object like a ship or turntable, an
accurate adjustment cannot be made. Move the vehicle on the
ground (or the part not causing vibrations to the vehicle) and make
an adjustment from step 1.

STARTING AND DRIVING
176
CAUTION
Do not rely excessively on the vehicle skid control system.
Even if the vehicle skid control system is operating, it is not
that your vehicle is absolutely safe. Reckless driving will
result in an unexpected accident. Always keep safety
driving in mind. If the slip indicator light flashes, sounding
an alarm, special care should be taken while driving.
Only use tires of specified size. The size, manufacturer,
brand and tread pattern for all 4 tires should be the same.
If you use the tires other than specified, or different type or
size, the vehicle skid control system may not function
correctly. When replacing the tires or wheels, contact your
Lexus dealer.
BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic system with
two separate subsystems. If either subsystem should fail, the other
will still work. However, the pedal will be harder to press, and your
stopping distance will be longer. Also, the brake system warning
light may come on.
CAUTION
Do not drive your vehicle with only a single brake system.
Have your brakes fixed immediately.
Brake booster
The brake booster uses engine vacuum to powerassist the brakes.
If the engine should quit while you are driving, you can bring the
vehicle to a stop with normal pedal pressure. There is enough
reserve vacuum for one or two stops but no more!
CAUTION
Do not pump the brake pedal if the engine stalls. Each push
on the pedal uses up your vacuum reserve.
Even if the power assist is completely lost, the brakes will
still work. But you will have to push the pedal hard much
harder than normal. And your braking distance will be
longer.

STARTING AND DRIVING
178”ABS” warning light
31L019-2
This light comes on when the ignition key is turned to the ”ON”
position. After about a few seconds, the light will go off.
If either of the following conditions occurs, this indicates a
malfunction somewhere in the parts monitored by the warning light
system. Contact your Lexus dealer as soon as possible to service the
vehicle.
The light does not come on as described above, or remains on.
The light comes on while driving.
Even if the antilock brake system should fail, the brake system will
still operate conventionally. But when the ”ABS” warning light is
on (and the brake system warning light is off), antilock brake
system is not assisting brake performance so that the wheels could
lock up during a sudden brake or braking on slippery road surfaces.
Have your vehicle checked by your Lexus dealer as soon as possible.
Drumindisc type parking brake system
Your vehicle has a drumindisc type parking brake system. This
type of brake system needs beddingdown of the brake shoes
periodically or whenever the parking brake shoes and/or drums are
replaced.
Have your Lexus dealer perform the beddingdown.
Brake pad wear limit warning message
31L082
When your brake pads are worn enough to require replacement,
the brake pad wear warning message in the multi information
display appears.
If the warning message in the multi information display appears
while driving, have the brake pads checked and replaced by your
nearest Lexus dealer immediately.
Continuous driving without replacing the brake pads will cause
expensive rotor damage and increasing brake pedal effort to get the
same stopping distance.
