FRONT PASSENGER AIRBAG ASSEMBLY
(1)

Always store a removed or new front passenger air-
bag assembly with the airbag deployment direction
facing up.
Storing the airbag assembly with the airbag deploy-
ment direction facing down could cause a serious
accident if the airbag inflates.

(2)

Never measure the resistance of the airbag squib.
(This may cause the airbag to deploy, which is very
dangerous.)

(3)

Grease should not be applied to the front passen-
ger airbag assembly and the airbag door should not
be cleaned with detergents of any kind.

(4)

Store the airbag assembly where the ambient tem-
perature remains below 93

°

C (200

°

F), without high

humidity and away from electrical noise.

(5)

When using electric welding, first disconnect the air-
bag connector (yellow color and 2 pins) installed on
the glove compartment finish plate at the left side of
the glove compartment before starting work.

(6)

When disposing of a vehicle or the airbag assembly
alone, the airbag should be deployed using an SST
before disposal (See page

RS–25

).

Perform the operation in a safe place away from
electrical noise.

AIRBAG SENSOR ASSEMBLY
(1)

Never reuse the airbag sensor assembly involved
in a collision when the SRS has deployed.

(2)

The connectors to the airbag sensor assembly
should be connected or disconnected with the sen-
sor mounted on the floor. If the connectors are con-
nected or disconnected while the airbag sensor as-
sembly is not mounted to the floor, it could cause
undesired ignition of the supplemental restraint sys-
tem.

(3)

Work must be started after 90 seconds from the
time the ignition switch is turned to the ”LOCK” posi-
tion and the negative (–) terminal cable is discon-
nected from the battery, even if only loosening the
set bolts of the airbag sensor assembly.

(g)

WIRE HARNESS AND CONNECTOR
The SRS wire harness is integrated with the cowl wire har-
ness assembly and floor wire harness assembly. The
wires for the SRS wire harness are encased in a yellow
corrugated tube. All the connectors for the system are
also a standard yellow color. If the SRS wire harness be-
comes disconnected or the connector becomes broken
due to an accident, etc., repair or replace it as shown on
page

RS–39

.

FOR VEHICLES WITH AN AUDIO SYSTEM WITH
BUILT–IN ANTI–THEFT SYSTEM

Audio System displaying the sign ”ANTI–THEFT SYSTEM”
shown on the left has a built–in anti–theft system which makes
the audio system soundless if stolen.
If the power source for the audio system is cut even once, the
anti–theft system operates so that even if the power source is
reconnected, the audio system will not produce any sound un-
less the ID number selected by the customer is input again. Ac-
cordingly, when performing repairs on vehicles equipped with
this system. before disconnecting the battery terminals or re-
moving the audio system the customer should be asked for the
ID number so that the technician can input the ID number after-
wards, or else a request made to the customer to input the ID
number. For the method to input the ID number or cancel the
anti–theft system, refer to the Owner’s Manual.

FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER

CAUTION:
If large amount of unburned gasoline flows into the converter, it may overheat and create a fire haz-
ard. To prevent this, observe the following precautions and explain them to your customer.
(a)

Use only unleaded gasoline.

(b)

Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20 minutes.

(c)

Avoid spark jump test.
(1)

Perform spark jump test only when absolutely necessary. Perform this test as rapidly as possible.

(2)

While testing, never race the engine.

(d)

Avoid prolonged engine compression measurement.
Engine compression tests must be done as rapidly as possible.

(e)

Do not run engine when fuel tank is nearly empty.
This may cause the engine to misfire and create an extra load on the converter.

(f)

Avoid coasting with ignition turned off and prolonged braking.

(g)

Do not dispose of used catalyst along with parts contaminated with gasoline or oil.

4.

IF VEHICLE IS EQUIPPED WITH MOBILE COMMUNICATION SYSTEM

For vehicles with mobile communication systems such as two–way radios and cellular telephones, observe
the following precautions.

(1)

Install the antenna as far as possible away from the ECU and sensors of the vehicle’s electronic
system.

(2)

Install the antenna feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the ve-
hicle’s electronic systems. For details about ECU and sensors locations, refer to the section on
the applicable component.

(3)

Do not wind the antenna feeder together with the other wiring as much as possible, also avoid
running the antenna feeder parallel with other wire harnesses.

(4)

Check that the antenna and feeder are correctly adjusted.

(5)

Do not install powerful mobile communications system.

5.

FOR USING OBD II SCAN TOOL OR LEXUS HAND–HELD TESTER

CAUTION:
Observe the following for safety reasons:

Before using the OBD II scan tool or LEXUS hand–held tester, the OBD II scan tool’s instruction
book or LEXUS hand–held tester’s operator manual should be read throughly.

Be sure to route all cables securely when driving with the OBD II scan tool or LEXUS hand–held
tester connected to the vehicle. (i.e. Keep cables away from feet, pedals, steering wheel and
shift lever.)
