OPERATION
1. STEERING WHEEL PAD (with AIRBAG)
The inflater and bag of the SRS are stored in the steering wheel
pad and cannot be disassembled. The inflater contains a squib,
igniter charge, gas generator, etc., and inflates the bag when
instructed by the airbag sensor assembly.
2. SPIRAL CABLE (in COMBINATION SWITCH)
A spiral cable is used as an electrical joint from the vehicle body
side to the steering wheel.
3. FRONT PASSENGER AIRBAG ASSEMBLY
The inflater and bag of the SRS are stored in the front passen-
ger airbag assembly and cannot be disassembled. The inflater
contains a squib, igniter charge, gas generator, etc., and in-
flates the bag when instructed by the airbag sensor assembly.
4. SIDE AIRBAG ASSEMBLY
The inflater and bag of the SRS side airbag are stored in the
side airbag assembly and cannot be disassembled. The inflater
contains a squib, igniter charge, gas generator, etc., and in-
flates the bag when instructed by the side airbag sensor assem-
bly.
5. SEAT BELT PRETENSIONER
The seat belt pretensioner system is a component of the front

DRIVE BELT
INSPECTION
INSPECT DRIVE BELT
(a) Visually check the drive belt for excessive wear, frayed
cords, etc.
If any defect has been found, replace the drive belt.
HINT:
Cracks on the rib side of a drive belt are considered acceptable.
If the missing chunks from the ribs are found on the drive belt,
it should be replaced.
(b) Using a belt tension gauge, measure the belt tension.
Belt tension gauge:
DENSO BTG-20 (95506-00020)
Borroughs No. BT-33-73F
Drive belt tension:
New belt: 120 - 185 lbf
Used belt: 95 - 135 lbf
If the belt tension is not as specified, adjust it.
HINT:
ºNew beltº refers to a belt which has been used less than
5 minutes on a running engine.
ºUsed beltº refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing a belt, check that it fits properly in the
ribbed grooves.
Check with your hand to confirm that the belt has not
slipped out of the groove on the bottom of the pulley.
After installing a new belt, run the engine for about 5 min-
utes and recheck the belt tension.
