In a severe frontal impact, the 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.
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 a minor skin irritation. Be
sure to wash off any residue as soon as possible to
prevent any potential 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
swelling.
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.

Do not use accessories for the seats which
cover the parts where the side airbags inflate.
Such accessories may prevent the side airbags
from activating correctly, causing death or
serious injury.
 Do not modify or remove any wiring. Do not
modify, remove, strike or open any
components, such as the steering wheel pad,
steering wheel, column cover, front passenger
airbag cover, front seats or airbag sensor
assembly. Doing any of these may cause
sudden SRS airbag inflation or disable the
system, which could result in death or serious
injury.
 Do not modify or replace the seats or
upholstery of the front seats with the side
airbags. Such changes may disable the system
or cause the side airbags to inflate accidentally,
resulting in death or serious injury. Consult
your Lexus dealer if you insist on modifications
of this kind.
Failure to follow these instructions can result in
death or serious injury.NOTICE
Do not perform any of the following changes without consulting your Lexus dealer. Suchchanges can interfere with proper operation of the
SRS in some cases.
Installation of electronic devices such as a mobile two±way radio, cassette tape player orcompact disc player
Modification of the suspension system
Modification of the front end structure and sidestructure of the passenger compartment
Attachment of a grille guard (bull bar, kangaroobar, etc.), snowplow, winches or any otherequipment to the front end
Repairs made on or near the front fenders, front
end structure, console, steering column, steering wheel, dashboard near the frontpassenger airbag or front seats

STARTING AND DRIVING
312
Anti±lock brake system is not designed to shorten the
stopping distance: Always drive at the moderate speed
and maintain a safe distance from the vehicle in front of
you. Compared with vehicles without an anti±lock
brake system, your vehicle may require a longer
stopping distance in the following cases:
 Driving on rough, gravel or snow±covered roads.
 Driving with tire chains installed.
 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.
