If a circuit is not as specified, inspect the applicable circuit.
2. INSPECT SPEEDOMETER/ ON-VEHICLE
Using a speedometer tester, inspect the speedometer for allow-
able indication error and check the operation of the odometer.
HINT:
Tire wear and tire over or under inflation will increase the indica-
tion error.

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 paper 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).
HINT:
The H RH and H LH line is 0.4° below the horizontal line (H line) of the light axis.
(8) Start the engine.
(9) Turn the headlights ON.
(10) Check that the headlights properly strike the position 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 A, adjust the headlight aim to within the specified range.

2. DEPLOYMENT WHEN DISPOSING OF CURTAIN
SHIELD AIRBAG ASSEMBLY
NOTICE:

When disposing of the curtain shield airbag assem-
bly only, never use the customer's vehicle to deploy
the airbag.

Be sure to follow the procedure given below when de-
ploying the airbag.
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Remove the curtain shield airbag assembly (See page
RS-59).
(b) Cut off the deployment section in airbag from inflator.
(c) Using a service-purpose wire harness, tie down the cur-
tain shield airbag assembly to the tire.
Wire harness: Stripped wire harness section

or more (0.0019 in2. or more)
CAUTION:
If a wire harness which is too thin or some other thing is
used to tie down the curtain shield airbag assembly, it may
be snapped by the shock when the airbag is deployed. This
is highly dangerous. Always use a wire harness for vehicle
use which is at least 1.25 mm
2 (0.0019 in2.).
HINT:
To calculate the square of the stripped wire harness section-
Square = 3.14 x (Diameter)
2 divided by 4
(1) Passing the wire harness through the installation
holes as shown in the illustration.

(b) Check the tire runout.
Tire runout: 3.0 mm (0.118 in.) or less
2. ROTATE TIRE
HINT:

Rotate tires as shown in the illustration.

Rotate as shown in (B) if the spare tire is included in the
rotation.
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: 14.0 g (0.031 Ib) or less

Use the table below to help you find the cause of the problem. The numbers indicate the priority of the likely
cause of the problem. Check each part in order. If necessary, replace these parts.
(w/ Differential locking system):

Check that the transfer shift lever is shifted to the L position.

When switching differential Free e Lock, the indicator light will blink if the gears of the differen-
tial lock sleeve are not meshed. If this occurs, when the tires are rotated to apply differential
power to the differential, the differential locks and the indicator light lights up.
