This indicator comes on when the ignition key is turned to
the ºACCº or ºONº position. It goes off after about 6
seconds. This means the front seat belt pretensioners are
operating properly.
The warning light system monitors the airbag sensor
assembly, front airbag sensors, side airbag sensors, door side
airbag sensors, front seat belt pretensioner assemblies,
inflators, warning light, interconnecting wiring and power
sources. (For details, see ºService reminder indicators and
warning buzzersº on page 38.)

1Front airbag sensors
2Seat belt pretensioner assemblies
3SRS warning light
4Airbag sensor assembly
The front seat belt pretensioner system consists mainly 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.

Side airbags
In response to a severe side impact, the side airbags for
the driver or front passenger work together with the seat
belts to help reduce injury by inflating. The side airbags
help to reduce injuries mainly to 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
The side airbags inflate with considerable force. To
avoid potential death or serious injury when they inflate,
the driver and front passenger must:
 Wear their seat belts.
 Remain properly seated with their back upright and
against the seat at all times.
SV16061
The indicator comes on when the ignition key is turned to
the ºACCº or ºONº position. It goes off after about 6
seconds. This means the SRS airbags are operating
properly.
The warning light system monitors the airbag sensor
assembly, front airbag sensors, side airbag sensors, door side
airbag sensors, front seat belt pretensioner assemblies,
inflators, warning light, interconnecting wiring and power
sources. (For details, see ºService reminder indicators and
warning buzzersº on page 38.)

7Front airbag sensors
The SRS 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 sensors.
In a severe frontal impact, the driver and front passenger
airbag sensors detect deceleration and the system triggers the
front airbag inflators. In a severe side impact, the side airbag
sensor triggers the side airbag inflator. Then a chemical
reaction in the inflators quickly fills the airbags with non±toxic
gas to help restrain the forward or lateral motion of the
occupants.

STARTING AND DRIVING

3: Third range
The most suitable gear is selected automatically
between first and third gears according to the vehicle
speed or the running condition.
Slight engine braking will be obtained on a downhill
road.
Smooth running with less shifting will be obtained on an
uphill.
2: Second range First or second gear will be selected automatically
according to the vehicle speed or the running condition.
This range is used in the case that the engine braking is
necessary.
The gear position being used is shown on the instrument
cluster.
Each time you push the switch located on the front of the
steering wheel, the transmission downshifts (from º5º) to º4º\
,
º3º and then º2º.
When you push the switch located on the back of the steering
wheel, the transmission upshifts to º3º, º4º and then º5º\
.
For the precautions on each position, see the description on
the next page. Warning tone sounds twice in any of the following cases:

You attempt to downshift the transmission when it is not
possible to downshift due to the high vehicle speed.
 You attempt to downshift from º2º position.
 You attempt to upshift from º5º position.
If the ºMº indicator flashes, there is a problem somewhere
in the system. In this case, it should be noted that you
cannot downshift or upshift the transmission using the
switches on the steering wheel. Consult with your Lexus
dealer as soon as possible. The transmission works
exactly in the same way as when you put the selector lever
in the ºDº position.
CAUTION
Be careful when downshifting on a slippery surface.
The abrupt change in engine speed could cause the
vehicle to spin or skid.

STARTING AND DRIVING

4Resetting to a slower speed
Press the control lever downward in the ºSET/COASTº
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 ºSET/COASTº direction quickly within
0.6 seconds.
However, a quicker way to reset is to depress the brake pedal
and then press the control lever downward in the
ºSET/COASTº direction.
Even if you downshift the transmission from the ºDº position to
ºMº with the cruise control on, engine braking will not be
applied 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
ºRES/ACCº 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 ºCRUISEº indicator light in the instrument cluster flashes
five times and then goes out when using the cruise control, it
means that there is trouble in the cruise control system.
Contact your Lexus dealer.

TRACTION CONTROL SYSTEM
The traction control system automatically help control the
spinning of the rear wheels which may occur when
accelerating on slippery road surfaces, thus assisting
driver control the driving power of the rear wheels. When
you turn the ignition switch on, the traction control
system always turns on automatically, and the slip
indicator light w ill come on. The indicator lights will go off
after a few seconds.
SV31011

1Slip indicator light
2ºSNOWº indicator light
Leave the system on during ordinary driving so that it can
operate when needed. When traction control is applied,
the slip indicator light blinks. If your vehicle still skids
even though traction control is applied, more powerful
traction control is applied and the ºSNOWº indicator light
comes on. If the light flashes, this indicates a malfunction in the traction
control system. Contact your Lexus dealer as soon as
possible to service the vehicle.
SV31018
You can turn off the traction control system by pushing
the ºTRAC OFFº switch. The ºTRAC OFFº
indicator/warning light will then come on. Pushing the
ºTRAC OFFº switch a second time turns the system back
on and extinguishes the ºTRAC OFFº indicator/warning
light.
You may hear a sound in the engine compartment for a few
seconds when the engine is started or just after the vehicle is
started. This means that the traction control system is in the
self±check mode, and does not indicate malfunction.
When the traction control system is operating, you may feel
vibration of your vehicle, caused by operation of the brakes.
This indicates the system is functioning properly.
