Front seat belt pretensioners
The driver and front passenger’s seat belt pretensioners
are designed to be activated in response to a severe
frontal impact.
When the airbag sensor detects the shock of a severe frontal
impact, the front seat belts are quickly drawn back in by the
retractors so that the belts snugly restrain the front seat
occupants.
The front seat belt pretensioners are activated even with no
passenger in the front seat.
This indicator comes on when the ignition key is turned to
the “ON” position. It goes off after about 6 seconds. This
means the front seat belt pretensioners are operating
properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
front seat belt pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources. (For details, see
“Service reminder indicators and warning buzzers” on page 50
for instructions.)

2SRS warning light
3Front airbag sensors
4Airbag sensor assembly
The front seat belt pretensioner system mainly consists of the
above components, and their locations are shown in the
illustration.
The front seat belt pretensioners are controlled by the airbag
sensor assembly. The airbag sensor assembly consists of a
safing sensor and airbag sensor.
When the front seat belt pretensioners are activated, an
operating noise may be heard and a small amount of
smoke−like gas may be released. This gas is harmless and
does not indicate that a fire is occurring.
Once the front seat belt pretensioners have been activated, the
seat belt retractors remain locked.
CAUTION
Do not modify, remove, strike or open the front seat belt
pretensioner assemblies, airbag sensor or surrounding
area or wiring. Doing so may cause sudden operation of
the front seat belt pretensioners or disable the system,
which could result in death or serious injury.
Failure to follow these instructions can result in death
or serious injuries. Consult your Lexus dealer about
any repairs and modifications.
NOTICE
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the front seat belt
pretensioners in some cases.
 Installation of electronic devices such as a mobile
twoway radio, cassette tape player or compact disc
player
 Repairs on or near the front seat belt retractor
assemblies
 Modification of the suspension system
 Modification of the front end structure

CAUTION
The SRS curtain shield airbags inflate with considerable
force. To avoid potential death or serious injury when
they inflate, the driver, front passenger and rear outside
passengers must:
 Wear their seat belts properly.
 Remain properly seated with their back upright and
against the seat at all times.
The indicator comes on when the ignition key is turned to
the “ON” position. It goes off after about 6 seconds. This
means the SRS airbags are operating properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
front seat belt pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources. (For details, see

STARTING AND DRIVING

4Resetting to a slower speed
Press the control lever down ward in the “SET/COAST”
direction and hold it. Release the lever when the desired
speed is attained. While the lever is held downward, the
vehicle speed will gradually decrease.
When the difference between the actual vehicle speed and the
set speed is less than 5 km/h (3 mph), the set speed can be
lowered 1.6 km/h (1 mph) each time by pressing the control
lever downward in the “SET/COAST” direction quickly.
However, a quicker way to reset is to depress the brake pedal
and then press the control lever downward in the
“SET/COAST” direction.
Even if you downshift the transmission from the “D” position to
“4” with the cruise control on, engine braking will not be
enabled because the cruise control is not cancelled. To
decrease the vehicle speed, reset to a slower speed with the
cruise control lever or depress the brake pedal. If you use the
brake pedal, cruise control is cancelled.
5 Resuming the preset speed
If the preset speed is cancelled by pulling the control lever or
by depressing the brake pedal, pushing the lever up in the
“RES/ACC” direction will restore the speed set prior to
cancellation. However, once the vehicle speed falls below
about 40 km/h (25 mph), the preset speed will not be resumed.
Cruise control failure warning
If the “CRUISE” indicator light in the instrument cluster flashes
when using the cruise control, push the main switch to turn the
system off and then push it again to turn it on.
If any of the following conditions then occurs, there is some
trouble in the cruise control system. Contact your Lexus dealer
and have your Lexus inspected.
 The indicator light does not come on.
 The indicator light flashes again.
 The indicator light goes out after it comes on.

“TRAC
OFF” indicator light comes on for a few seconds when
the ignition key is turned to “ON”. It will come on again when
you push the “TRAC OFF” switch to turn off the system.
In the following cases, contact your Lexus dealer:
 The indicator light does not come on when the ignition key
is turned to “ON”.
 The indicator light remains on after the ignition is turned on.
 The indicator light comes on with the normal driving mode
while driving.
“VSC” warning light
This light warns that there is a problem somewhere in the
traction control system or the vehicle skid control 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 does not work.
However, as conventional braking operates when applied,
there is no problem to continue your driving.
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.

BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic
system with two separate sub −systems. If either sub −system
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 power −assist 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 reserved 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 reserved
vacuum.
 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.
Antilock brake system
The antilock brake system is designed to help prevent
lockup of the wheels during a sudden braking or braking
on slippery road surfaces. This assists in providing
directional stability and steering performance of the
vehicle under these circumstances.
Effective way to press the ABS brake pedal: When the
anti−lock brake system function is in action, you may feel the
brake pedal pulsating and hear a noise. In this situation, to
let the anti−lock brake system work for you, just hold the
brake pedal down more firmly. Do not pump the brake in a
panic stop. This will result in reduced braking performance.
The anti −lock brake system becomes operative after the
vehicle has accelerated to a speed in excess of approximately
10 km/h (6 mph). It stops operating when the vehicle
decelerates to a speed below approximately 5 km/h (3 mph).
Depressing the brake pedal on slippery road surfaces such as
on the manhole cover, the steel plate under the construction,
joints in the bridge, etc. on a rainy day tends to activate the
anti−lock brake system.

STARTING AND DRIVING
244“ABS” warning light
 1
U.S.A. 2 Canada
Vehicles without vehicle skid control system—
The light comes on when the ignition key is turned to the “ON”
position. If the anti −lock brake system works 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 anti− lock brake system does not
operate, but the brake system still operates conventionally.
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 could 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 parts monitored by the
warning light. 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.
Vehicles with vehicle skid control system—
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.
