COMFORT ADJUSTMENT
156The 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 is
operating properly.
The SRS warning light system monitors the airbag
sensor assemblies, inflators, seat belt pretensioners,
warning
light, interconnecting wiring and power sources.
(For details, see ºService reminder indicators and
warning buzzersº on page 62 for instructions.)

6SRS warning light
7Airbag 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
non±toxic 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 some smoke and residue along with
non±toxic gas. This does not indicate a fire. This gas is
normally harmless, however, for those who have
delicate skin, it may cause minor skin irritation. Be sure
to wash off any residue as soon as possible to prevent
minor skin irritation. 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
swellings.
Parts of the airbag module (steering wheel hub,
dashboard, front seats) may be hot for several minutes,
but the airbags themselves will not be hot. The airbags
are designed to inflate only once.
A crash severe enough to inflate the driver and front
passenger airbags may break the windshield as the
vehicle buckles. In vehicles with a front passenger
airbag, the windshield may also be damaged by
absorbing some of the force of the inflating airbag.

STARTING AND DRIVING
301
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 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.
 The indicator light does not come on.
 The indicator light flashes again.
 The indicator light goes out after it comes on.
If this is the case, contact your Lexus dealer and have
your Lexus inspected.
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.
