TIRE AND WHEEL
INSPECTION
1. INSPECT TIRE
(a) Check the tires for wear and proper inflation pressure.
Cold tire inflation pressure:
(Tire size: P175/65R14 84S)
FrontRear
240 kPa (2.4 kgf/cm2, 35 psi)230 kPa (2.3 kgf/cm2, 33 psi)
(b) Using a dial indicator, check the tire runout.
Tire runout: 1.0 mm (0.039 in.) or less
2. ROTATING TIRES
HINT:
See the illustration for where to rotate each tire.
3. INSPECT WHEEL BALANCE
(a) Check and adjust the Off±the±car balance.
(b) If necessary, check and adjust the On±the±car balance.
Imbalance after adjustment: 8.0 g (0.018 lb) or less
4. CHECK WHEEL BEARING LOOSENESS
(a) Using a dial indicator, check the backlash near the center
of the axle hub.
Maximum: 0.05 mm (0.0020 in.)
If the backlash exceeds the maximum, replace the bearing.
(b) Using a dial indicator, check the deviation at the surface
of the axle hub outside the hub bolt.
Maximum: 0.07 mm (0.0028 in.)
If the deviation exceeds the maximum, replace the axle hub.

(b) When the vehicle is involved in a frontal collision in the
hatched area (Fig. 1) and the shock is larger than the pre-
determined level, the SRS is activated automatically. A
safing sensor is designed to go on at a smaller decelera-
tion rate than the airbag sensor. As illustrated in Fig. 2,
ignition is caused when current flows to the squib, which
happens when a safing sensor and the deceleration sen-
sor go on simultaneously. When a deceleration force acts
on the sensors, 2 squibs in the driver airbag and front pas-
senger airbag ignite and generate gas. The gas discharg-
ing into the driver airbag and front passenger airbag rap-
idly increases the pressure inside the bags, breaking
open the steering wheel pad and instrument panel.
Bag inflation then ends, and the bags deflate as the gas
is discharged through discharge holes at the bag's rear or
side.
11. DISCONNECTION OF CONNECTORS FOR FRONT
AIRBAG SENSOR AND SIDE AIRBAG SENSOR
(a) While holding both flank sides of the outer, slide the outer
to the direction shown by an arrow.
(b) Lock of the connectors is released, then disconnect the
connectors.
HINT:
Be sure to hold both flank sides of the outer. If holding the top
and bottom sides, it will obstruct disconnection.

ADJUST HEADLIGHT AIM ONLY
(a) Place the vehicle in the following conditions.

The area around the headlight is not deformed.

The vehicle is parked on a level surface.

Tire inflation pressure is the specified value.

A driver is in the driver's seat and the vehicle is in
a state ready for driving (with a tank full).

The vehicle has been bounced several times.
(b) Check the headlight aiming.
(1) Prepare a thick white paper.
(2) Stand the paper perpendicular to the ground at the
position 9.84 ft away from the headlights.
(3) Ensure that the center line of the vehicle and the pa-
per face forms a 90±degree angle as shown in the
illustration.
(4) Draw a horizontal line (H line) on the paper, showing
where the headlights should strike.
(5) Draw a vertical line (V line) to where the center line
of the vehicle is to be.
(6) Draw 2 vertical lines (by connecting the low and
high beam center marks) to where the both head-
lights should strike (V RH and V LH lines).
(7) Draw a horizontal line (by connecting the both low
beam center marks) to where the headlights should
strike (H RH and H LH lines).
(8) Start the engine.
(9) Turn the headlights ON.
(10) Check that the headlights properly strike the posi-
tion shown in the illustration.
(11) If not, adjust the lights in the vertical direction.
HINT:
As shown in the illustration, adjust each aim of the RH and LH
lights.
(c) When adjusting it in the vertical direction:
Using adjusting bolt, adjust the headlight aim to within the
specified range.
