PRECAUTION

1.

FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND
SEAT BELT PRETENSIONER

(a)

The SEQUOIA is equipped with an SRS (Supplemental
Restraint System), such as the driver airbag, front pas-
senger airbag, side airbag assembly, curtain shield airbag
assembly and seat belt pretensioner.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to
unexpectedly deploy during servicing, possibly leading to
a serious accident.
Further, if a mistake is made in servicing the supplemental
restraint system, it is possible the SRS may fail to operate
when required. Before servicing (including removal or
installation of parts, inspection or replacement), be sure
to read the following items carefully, then follow the cor-
rect procedure described in this manual.

(b)

GENERAL NOTICE
(1)

Malfunction symptoms of the supplemental re-
straint system are difficult to confirm, so the diag-
nostic trouble codes become the most important
source of information when troubleshooting.  When
troubleshooting  the supplemental restraint system,
always inspect the diagnostic trouble codes before
disconnecting the battery (See page 

DI–1118

).

(2)

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.
(The supplemental restraint system is equipped
with a back–up power source because if work is
started within 90 seconds of disconnecting the neg-
ative (–) terminal cable from the battery, the SRS
may deploy.)
When the negative (–) terminal cable is discon-
nected from the battery, memory of the clock and
audio systems will be cancelled.  So before starting
work, make a record of the contents memorized in
each memory system. When work is finished, reset
the clock and audio systems as before. To avoid
erasing the memory of each memory system, never
use a back–up power supply from another battery.

(3)

Even in case of a minor collision where the SRS
does not deploy, the steering wheel pad, the pas-
senger airbag assembly, side airbag assembly, cur-
tain shield airbag assembly, seat belt pretensioner,
airbag sensor assembly, front airbag sensor, side
airbag sensor assembly and curtain shield airbag
sensor assembly should be inspected.

(4)

Never use SRS parts from another vehicle. When
replacing parts, replace them with new ones.

(5)

Before repairs, remove the airbag sensor because
shocks are likely to be applied to the sensor during
repairs.

(6)

Never disassemble or repair the steering wheel
pad, front passenger airbag assembly, airbag sen-
sor assembly and front airbag sensor.

(7)

If the steering wheel pad, front passenger airbag
assembly, side airbag assembly, curtain shield air-
bag assembly, seat belt pretensioner, airbag sensor
assembly and front airbag sensor have been
dropped, or if there are cracks, dents or other de-
fects in the case, bracket or connector, replace
them with new ones.

(8)

Do not expose the steering wheel pad, front pas-
senger airbag assembly, side airbag assembly, cur-
tain shield airbag assembly, seat belt pretensioner,
airbag sensor assembly and front airbag sensor di-
rectly to hot air or flames.

(9)

Use a volt/ohmmeter with high impedance (10 k

Ω

/V

minimum) for troubleshooting of the electrical cir-
cuit.

(10) Information labels are attached to the periphery of

the SRS components. Follow the instructions on the
notices.

(11) After work on the supplemental restraint system is

completed, check the SRS warning light (See page

DI–1118

).

SPIRAL CABLE (in Combination Switch)
The steering wheel must be fitted correctly to the steering
column with the spiral cable at the neutral position, other-
wise cable disconnection and other troubles may result.
Refer to 

DI–1118

 concerning correct steering wheel

installation.

(d)

STEERING WHEEL PAD (with Airbag)
(1)

When removing the steering wheel pad or handling
a new steering wheel pad, it should be placed with
the pad top surface facing up.
Storing the pad with its metallic surface upward may
lead to a serious accident if the airbag inflates for
some reason. In addition do not store a steering
wheel pad on top of another one.

(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 steering wheel
pad and the pad should not be cleaned with any
kind of detergents.

(4)

Store the steering wheel pad where the ambient
temperature 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) under the
steering column near the combination switch con-
nector before starting work.

(6)

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

RS–23

).

Carry out the operation in a safe place away from
electrical noise.
