4. 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.

2. 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, adjust the headlight aim to within the specified range.

INSPECTION
CAUTION:
Replace the seat belt assembly (outer belt, inner belt, bolts,
nuts or sill-bar) if it has been used in a severe impact. The
entire assembly should be replaced even if damage is not
obvious.
1. RUNNING TEST (IN SAFE AREA)
(a) Fasten the front seat belts.
(b) Drive the car at 10 mph (16 km/h) and slam on the brakes.
Check that the belt locks and cannot be extended at this
time.
HINT:
Conduct this test in a safe area. If the belt does not lock, remove
the belt mechanism assembly and conduct the following static
check. Also, whenever installing a new belt assembly, verify the
proper operation before installation.
2. Driver 's seat belt (ELR):
STATIC TEST
(a) Make sure that the belt locks when pulled out quickly.
(b) Remove the locking retractor assembly.
(c) Tilt the retractor slowly.
(d) Make sure that the belt can be pulled out at a tilt of 15 de-
grees or less, and cannot be pulled out over 45 degrees
of tilt.
If a problem is found, replace the assembly.
3. Except driver's seat belt (ALR/ELR):
STATIC TEST
(a) Make sure that the belt locks when pulled out quickly.
(b) Remove the locking retractor assembly.
(c) Pull out the whole belt and measure the length of the
whole belt.
Then retract the belt slightly and pull it out again
(d) Make sure that the belt cannot be extended further.
