INTRODUCTION - FOR ALL OF VEHICLES
FOR ALL OF VEHICLES IN0I8-01
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG
(a) The 4RUNNER is equipped with an SRS (Supplemental
Restraint System), such as the driver airbag, front pas-
senger airbag 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
Negative Cable
(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-377 ).
BO4111 (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
so that if work is started within 90 seconds of discon-
necting the negative (-) terminal cable from the bat-
tery, 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 by
the each memory system. Then when work is fin-
ished, reset the clock and audio systems as before.
To avoid erasing the memory of each memory sys-
tem, never use a back-up power supply from anoth-
er battery.

INTRODUCTION - FOR ALL OF VEHICLES
(3) Even in cases of a minor collision where the SRS
does not deploy, the steering wheel pad, front pas-
senger's airbag assembly and seat belt pretension-
er should be inspected (See page RS-12 , RS-26
and BO-1 19).
(4) Never use SRS parts from another vehicle. When
replacing parts, replace them with new parts.
(5) Before repairs, remove the airbag sensor if shocks
are likely to be applied to the sensor during repairs.
(6) Never disassemble and repair the airbag sensor as-
sembly, steering wheel pad, front passenger air bag
or seat belt pretensioner.
(7) If the airbag sensor assembly, steering wheel pad,
front passenger airbag or seat belt pretensioner has
been dropped, or if there are cracks, dents or other
defects in the case, bracket or connector, replace
them with new ones.
(8) Do not directly expose the airbag sensor assembly,
steering wheel pad, front passenger airbag or seat
belt pretensioner directly to hot air or flames.
(9) Use a volt/ohmmeter with high impedance (10 k/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-377 ).
(c) 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 SR-20 concerning correct steering wheel instal-
lation.

(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 facing up-
ward may lead to a serious accident if the airbag in-
flates 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 deter-
gents of any kind.
(4) Store the steering wheel pad where the ambient
temperature remains below 93◦ Jabse Service Manual Search 2026 ◦ Jabse Pravopis ◦ onTap.bg ◦ Other service manual resources online : Fixya ◦ eServiceinfo
