FOR ALL OF VEHICLES

PRECAUTION

1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND

SEAT BELT PRETENSIONER

(a) The SIENNA is equipped with an SRS (Supplemental Re-

straint System), such as the driver airbag, front passen-

ger airbag assembly, side 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-358 ).

(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 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 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.

(3) Even in cases of a minor collision where the SRS

does not deploy, the steering wheel pad, front pas-

senger airbag assembly and seat belt pretensioner

should be inspected (See page RS-14 , RS-28 ,

and BO-155 ).

(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 airbag

assembly or seat belt pretensioner.

(7) If the airbag sensor assembly, steering wheel pad,

front passenger airbag assembly or seat belt pre-

tensioner have been dropped, or if there are cracks,

dents or other defects in the case, bracket or con-

nector, replace them with new ones.

(8) Do not directly expose the airbag sensor assembly,

steering wheel pad, front passenger airbag assem-

bly or seat belt pretensioner to hot air or flames.

(9) Use a volt/ohmmeter with high impedance (10 kΩ/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-358 ).

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 of this manual concerning correct steer-

ing 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.

In this case, care should be taken to place it so the

connector will not be damaged. In addition do not

store a steering wheel pad on top of another one.

Storing the pad with its metallic surface up may lead

to a serious accident if the airbag inflates for some

reason.

(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 attached to the steering

wheel pad and the pad should not be cleaned with

detergents of any kind.

(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-16 ).

Carry out the operation in a safe place away from

electrical noise.

(h) 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 loosing the set

bolts of the airbag sensor assembly.
