SRS AIRBAG

PRECAUTION

CAUTION:

The vehicle is equipped with SRS, which consists of a driver airbag, front passenger airbag,
side airbag and curtain shield airbag. Failure to carry out service operations in the correct se-
quence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a
serious accident. Further, if a mistake is made in servicing the SRS, it is possible that the SRS
may fail to operate when required. Before performing servicing (including removal or installa-
tion of parts, inspection or replacement), be sure to read the following items carefully, then fol-
low the correct procedures indicated in the repair manual.

Wait at least 90 seconds after the ignition switch is turned to the ”LOCK” position and the nega-
tive (–) terminal cable is disconnected from the battery.
(The SRS is equipped with a back–up power source, so that if work is started within 90 seconds
after disconnecting the negative (–) terminal cable of the battery, the SRS may be deployed.)

Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly,
curtain shield airbag assembly, airbag sensor assembly, front airbag sensor, side airbag sen-
sor assembly, curtain shield airbag sensor assembly, seat position sensor assembly or occu-
pant classification ECU directly to hot air or flames.

Be sure to perform the initialization of the occupant classification ECU if any of the following
conditions occur (see page 

DI–1128

). If the initialization is not performed, the SRS may not oper-

ate properly.

The occupant classification ECU is replaced.

Accessories (seatback tray, seat cover, etc.) are installed to the vehicle.

The passenger seat is removed from the vehicle, and then reinstalled or replaced.

The passenger airbag ON/OFF indicator light (”OFF”) comes on when the passenger seat
is not occupied.

The vehicle is brought to the workshop for repair due to an accident or collision.

NOTICE:

Malfunction symptoms of the SRS are difficult to confirm, so DTCs are the most important
source of information when troubleshooting. When troubleshooting the SRS, always inspect
DTCs before disconnecting the battery.

Even in the case of a minor collision when the SRS does not deploy, the steering wheel pad,
front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, airbag
sensor assembly, front airbag sensor, side airbag sensor assembly, curtain shield airbag sen-
sor assembly, seat position sensor assembly and occupant classification ECU should be in-
spected. (see page

).

Before repair work, remove the airbag sensor if any kind of shock is likely to occur to the airbag
sensor during the operation.

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

Never disassemble or repair the steering wheel pad, front passenger airbag assembly, side air-
bag assembly, curtain shield airbag assembly, airbag sensor assembly, front airbag sensor,
side airbag sensor assembly, curtain shield airbag sensor assembly, seat position sensor as-
sembly or occupant classification ECU in order to reuse it.
