covered under warranty.
Spark ignition system of your Lexus
The spark ignition system in your Lexus meets all
requirements of the Canadian Interference±Causing

Installation of a mobile two±way radio
system
As the installation of a mobile two±way radio system in
your

multiport fuel injection system/sequential multiport fuel
injection system, cruise control system, anti±lock brake
system and Supplemental Restraint System (SRS), be
sure to check with your Lexus dealer for precautionary
measures or special instructions regarding installation.
Scrapping of your Lexus
The Supplemental Restraint System (SRS) in your
Lexus consists of driver and front passenger airbags,
side airbags and seat belt pretensioners. The SRS
device contains explosive chemicals. If the vehicle is
scrapped with the airbags and seat belt pretensioners
left as they are, it may cause an accident such as a fire.
Be sure to have the SRS removed and disposed of by
a qualified service shop or by your Lexus dealer before
you scrap your vehicle.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
60If the brake fluid level is correct ...
Have
the warning system checked by your Lexus dealer.
(b) Seat Belt Reminder Light and Buzzer
Once the ignition key is turned to ºONº or ºSTARTº, the
reminder light and buzzer come on if the driver's seat
belt is not fastened. Unless the driver fastens the belt,
the light stays on and the buzzer stops after about 4 to
8 seconds.
(c) SRS Warning Light
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 is
operating properly.
The SRS warning light system monitors the airbag
sensor assemblies, front airbag sensors, inflators, seat
belt pretensioners, warning light, interconnecting wiring
and power sources.
If either of the following conditions occurs, this indicates
a malfunction somewhere in the parts monitored by the
warning light system. Contact your Lexus dealer as
soon as possible to service the vehicle.
The light does not come on as described above.
 The light stays on or flashes.
 The light comes on or starts flashing while driving.
If the light stays on, it indicates that the driver and front
passenger airbags fail. If the light flashes, the side
airbags and/or seat belt pretensioners fail.

CAUTION
The SRS side airbags are installed in the driver and front
passenger seats. Observe the following precautions.
Do not lean over the front door when the vehicle is in
use. The side airbag inflates with considerable speed
and force; you may be killed or severely injured.
 Do not modify or replace the seats or the surface of
the seats with side airbags. Such changes may
disable the system, or cause the side airbags to
inflate, resulting in death or serious injury. Consult
your Lexus dealer.
 Do not use accessories for the seats which cover the
parts where the side airbags should inflate. Such
accessories may prevent the side airbags from
activating correctly, causing death or serious injury.

SUPPLEMENTAL RESTRAINTSYSTEM (SRS)
The Supplemental Restraint System (SRS) consists
of driver and front passenger airbags, side airbags
and seat belt pretensioners. The combination of
these 3 systems is designed to provide further
protection for the driver and front passenger when
added to the primary protection provided by the seat
belts.

CAUTION
SRS side airbags inflate with considerable force. To
avoid potential death or serious injury during inflation
of a side airbag, Lexus strongly recommends that the
driver and front passenger;
Wear their seat belt.
 Remain properly seated with their back against the
seat at all times.
