KEYS AND DOORS
28The back door can be locked and unlocked together with the
side doors by means of the power door lock system. (For
instructions, see ªLocking with power door lock switchº on
page 24.)
See ªStowage precautionsº on page 485 for precautions when
loading luggage.
CAUTION

Keep the back door closed while driving. This not
only keeps the luggage from being thrown out but
also prevents exhaust gases from entering the
vehicle.
 If the open back door hides the rear stop and tail
lights or rear turn signal lights while you are parked,
other road users must be warned of the presence of
your vehicle by a warning triangle or other device.
Back door stopper

1Lock2Unlock
For your safety, lock the back door with the door stopper
when you fully open the back door.
When closing the back door, check that the back door stopper
is unlocked.
CAUTION
 When keeping the back door open, use only the lock
lever of the back door stopper without touching the
other parts.
 To avoid serious personal injury, make sure not to get
your hands caught in the back door stay when
closing the back door.

GAUGES, METERS AND SERVICE REMINDER INDICATORS

(j) ªVSC TRACº Warning Light
This light warns that there is a problem somewhere in the
following.
Vehicle stability control system
 Active traction control system
 Downhill assist control system
 Hill±start assist control
The light will come on when the ignition key turned to ªONº, and
will go off after a few seconds.
It is not a malfunction that the warning light may stay on for 60
seconds after the ignition key is turned to the ªONº position.
Depressing the brake pedal repeatedly may turn on the lights.
It is normal if they go out after a few seconds.
If the light comes on while driving, the above mentioned
systems do 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 ªONº.
 The warning light remains on after the ignition key is turned
to ªONº.
 The warning light comes on while driving.
When the brake fluid level is too low, the above±mentioned
systems will not operate and the warning light come on.
(k) ªKDSSº Warning Light (vehicles with kinetic dynamic suspension system)
This light warns that there is a problem somewhere in the
kinetic dynamic suspension system.
The light will come on when the ignition key is turned to the
ªONº position and will go off after a few seconds.
If the light comes on while driving, bring your vehicle to your
Lexus dealer as soon as possible and have it checked.
(l) Discharge Warning Light
This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn off the
engine, and check for the cause. Look first at the engine drive
belt.
 If it is loose or broken, the generator will not charge the
battery properly.
 If the belt is O.K., there is a problem somewhere in the
charging system.
The engine ignition will continue to operate, however, until the
battery is discharged. Turn off the air conditioning, blower,
radio, etc., and drive directly to the nearest Lexus dealer or
repair shop.

OCCUPANT RESTRAINT SYSTEMS

1Airbag module for front passenger
(airbag and inflator)
2Front passenger occupant classification system(ECU and sensors)
3ªAIRBAG ONº and ªAIRBAG OFFº indicator lights
4SRS warning light
5Airbag module for driver (airbag and inflator)
6Driver's seat position sensor
7Driver's seat belt buckle switch
8Front passenger's seat belt buckle switch
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.

The SRS side airbag and curtain shield airbag system consists
mainly of the above components, and their locations are shown
in the illustration.
The SRS side airbag and curtain shield airbag system is
controlled by the airbag sensor assembly. The airbag sensor
assembly consists of a safing sensor and airbag sensor.
In a severe side impact, the side and curtain shield airbag
sensor and/or the curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain shield airbag inflators.
At this time a chemical reaction in the inflators quickly fills the
airbags with non±toxic gas to help restrain the lateral motion
of the occupants. In a vehicle rollover, the airbag sensor assembly triggers the
curtain shield airbag inflator. At this time, a chemical reaction
in the inflators quickly fills the airbags with non±toxic gas to
help restrain the lateral motion of the occupants.
When the airbags inflate, they produce a fairly 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 can 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, it may also
cause minor burns or abrasions and swelling.
Front seats as well as parts of the front and rear pillars, and roof
side rail may be hot for several minutes, but the airbags
themselves will not be hot. The airbags are designed to inflate
only once.
