When the vehicle is involved in a frontal collision in the
hatched area (Fig. 1) and the shock is larger than a predeter-
mined level, the SRS is activated automatically. A safing sen-
sor is designed to go on at a smaller deceleration rate than
the front and center airbag sensors. As illustrated in Fig. 2,
ignition is caused when current flows to the squib, which hap-
pens when a safing sensor and a front airbag sensor and/or
the center airbag sensor go on simultaneously. When a de-
celeration force acts on the sensors, two squibs in the driver
airbag and front passenger airbag ignite and generate gas.
The gas discharging into the driver and front passenger air-
bags rapidly increases the pressure inside the bags, break-
ing open the steering wheel pad and instrument panel door.
Bag inflation then ends, and the bags deflate as the gas is
discharged through discharge holes at the bag's rear or side. RS±8

GENERAL INSPECTION
1. INSPECT TIRE
(a) Check the tires for wear and for the proper inflation pressure.
Cold tire inflation pressure (2JZ±GE)
Tire size
Front
kPa (kgf/cm2, psi)
Rear
kPa (kgf/cm2, psi)
225/50ZR16 230 (2.3, 33) ±±
245/50ZR16 ±± 250 (2.5, 36)
Cold tire inflation pressure (2JZ±GTE)
Tire size
Front
kPa (kgf/cm2, psi)
Rear
kPa (kgf/cm2, psi)
235/45ZR17 250 (2.5, 36) ±±
255/40ZR17 ±± 250 (2.5, 36)
(b) Check the tire runout.
Tire runout:
Less than 1.4 mm (0.055 in.)
2. INSPECT WHEEL BALANCE
(a) Check and adjust the Off±the±car balance.
(b) If necessary, check and adjust the On±the±car balance.
Unbalance after adjustment:
5.0 g (0.011 lb) or less
3. CHECK WHEEL BEARING LOOSENESS
(a) Check the backlash in bearing shaft direction.
Maximum: 0.05 mm (0.0020 in.)
(b) Check the axle hub deviation.
Maximum: 0.05 mm (0.0020 in.)
4. CHECK FRONT SUSPENSION FOR LOOSENESS
5. CHECK STEERING LINKAGE FOR LOOSENESS
6. CHECK BALL JOINT FOR LOOSENESS
7. CHECK SHOCK ABSORBER WORK PROPERLY
wCheck for oil leak
wCheck mounting bushings for wear
wBounce front and rear of the vehicle
