The indicator comes on when the ignition key is turned to
the ªONº position. It goes off after about 6 seconds. This
means the SRS side airbags and curtain shield 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 passenger occupant classification system, ªAIRBAG ONº
indicator light, ªAIRBAG OFFº indicator light, front passenger's
seat belt buckle switch, front seat belt pretensioner
assemblies, inflators, warning light, ªRSCA OFFº indicator
light, interconnecting wiring and power sources. (For details,
see ªService reminder indicators and warning buzzersº on
page 62 for instructions.) If any of the following conditions occurs, this indicates a
malfunction of the airbags or seat belt pretensioners. Contact
your Lexus dealer as soon as possible.

The light does not come on when the ignition key is turned
to the ªONº position or remains on for more than 6 seconds
or flashes.
 The light comes on or starts flashing while driving.
The SRS warning light and ªAIRBAG OFFº indicator light will
be illuminated if there is a malfunction in the front passenger
occupant classification system.

When the outside air temperature is low, it may take a little
longer for the mirror to darken in response to the detection of
headlights.
CAUTION
Do not adjust the mirror while the vehicle is moving.
Doing so may cause the driver to mishandle the vehicle
and an accident may occur resulting in death or serious
injuries.
To ensure correct functioning of anti±glare mirror sensors
located on both sides of the mirror, do not touch or cover
the sensors with your finger or a piece of cloth, etc.
Compass
The compass indicates the direction in which the vehicle
is heading. The illustration shown above indicates the
vehicle is heading north.
Push the ªCOMPº switch to turn the compass system on
and off.
If the ignition switch was turned off with the system on, the
system
will automatically turn back on when the ignition switch
is turned on.

NOTICE
Do not put magnets or a metal object on or near the
inside rear view mirror of the vehicle. Doing this maycause malfunction of the compass sensor in the mirror.

NOTICE
To prevent the battery from being discharged, do notuse the power outlet longer than necessary when theengine is not running.
Close the power outlet lid when the power outlet isnot in use. Inserting anything other than anappropriate plug that fits the outlet, or allowing anyliquid to get into the outlet may cause electricalfailure or short circuits.
The power outlet is not designed for the following electric
appliances even though their power consumption is
under 115 VAC/100W. These appliances may not operate
properly.
 Appliances with high initial peak wattage: Cathode±ray
tube type televisions, compressor±driven refrigerators,
electric pumps, electric tools, etc.
 Measuring devices which process precise data: Medical
equipment, measuring instruments, etc.
 Other appliances requiring an extremely stable power
supply: Microcomputer±controlled electric blankets, touch
sensor lamps, etc.
Certain electrical appliances may cause radio noise.Headphone input jacks
To use the jack, push the lid.

STARTING AND DRIVING
444
Driving over the steps such as the joints on the road.
 Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate
pressure: The anti±lock brake system detects vehicle
speeds using the speed sensors for respective wheels'
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.ªABSº warning light

1U.S.A.2Canada
The light comes on when the ignition key is turned to the ªONº
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 ªABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system, the brake
assist system, the active traction control system and the
vehicle stability control system do/does not operate, but the
brake system still operates conventionally.
When the ªABSº 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.

STARTING AND DRIVING
448
NOTICE
Do not use liquid sealants for a flat tire as air pressuresensors will be damaged.
When the tires must be repaired or replaced, havethem repaired or replaced by the nearest Lexusdealer or authorized tire dealer. The tire pressuresensors will be affected by the installation or removal
of tires.
The tire pressure warning system is not to be used as a substitute for regular inspections. Be sure to check
the air pressure in the tires on a regular basis.
When the tires must be replaced, replace the grommets for air pressure sensors as well.
If the warning light blinks:
The tire pressure warning system may be malfunctioning.
Contact your Lexus dealer.System malfunction
The tire pressure warning system does not function
properly under certain circumstances. In the following
cases, the low tire pressure warning light may not come
on even if the tire inflation pressure is low, or it may come
on when the tire inflation pressure is actually normal.
 Electric devices or facilities using similar radio wave
frequencies are nearby.
 A radio set to similar frequencies is in use.
 A lot of snow or ice covers the vehicle, in particular, around
the wheels or wheel housings.
 The tires are not equipped with an air pressure sensor.
 Tire chains are used.

STARTING AND DRIVING
449

Non±genuine Lexus wheels are used.
 Although the tires are equipped with air pressure sensors,
the selector switch (see page 455.) is set to other tire setting.
CAUTION
The use of non±genuine wheels will cause the air
pressure sensors to transmit the electronic code in
different manner, resulting in the system failure.
 The use of different type of tires with genuine wheels
may also cause the malfunction of the system.

STARTING AND DRIVING
454
Replacing tires and wheels
When replacing the wheels, be sure to install air pressure
sensors on the wheels.
There are 3 ways to set up the air pressure sensors:
(a) Remove the sensor from the old wheel and install it to the
new wheel.
(b) Keep the same wheel with air pressure sensor and replace
only the tire.
(c) Use a new wheel and sensor.
You have to register an ID code for a new sensor. Up to 2 sets
of codes can be registered. As one ID for the originally installed
sensor is registered at ªMAINº of the selector switch, use the
ª2ndº position to register an ID for the new sensor.
You do not need to re±register the ID code for any other
replacements. For the use of the originally installed tires, put
the selector switch at ªMAINº and for the use of tires set
purchased later, put the switch at ª2ndº. For the sensor
selector switch, see page 455.CAUTION
 Have the tires, wheels or sensors replaced and ID
codes registered by a Lexus dealer. If you need
sensors, purchase from a Lexus dealer.
 The use of non±genuine wheels will cause the air
pressure sensors to transmit the electronic code in
different manner, resulting in the failure of the
system.
