PRECAUTION

1. PRECAUTION FOR USING BATTERY DURING INSPECTION

(a) While using the battery during inspection, do not

bring the positive and negative tester probes too close to each other as a short circuit may occur.

2. PRECAUTION FOR HEADLIGHT BULB REPLACEMENT

(a) If even a thin film of oil is left on the surface of the

halogen light, the bulb may be damaged because the light will burn at a higher temperature.

(b) Handle any halogen light with great care. Dropping,

hitting or damaging the bulb, in any way, may result in exploding and shattering because the internal pressure is high.

replacement. While replacing the bulb, the lens may attract dust and moisture if removed from the vehicle for too long.

(d) Always use a bulb of the same wattage for

replacement.

(e) Firmly reinstall the socket after bulb replacement.

The lens may become cloudy or the light cavity may fill with water through the gaps around the socket.

ADJUSTMENT

HINT: It is possible that a bulb is incorrectly installed, affecting headlight aim. Bulb installation should be considered prior to performing the adjustment procedure.

1. VEHICLE PREPARATION FOR HEADLIGHT AIM

ADJUSTMENT

(a) Prepare the vehicle according to the following

conditions:

• Ensure there is no damage or deformation to the body around the headlights.

• Fill the fuel tank.

• Make sure that the oil is filled to the specified level.

• Make sure that the coolant is filled to the specified level.

• Inflate the tires to the appropriate pressure.

• Unload the trunk and vehicle, ensuring that the spare tire, tools, and jack are in their original positions.

• Sit a person of average weight (68 kg, 150 lb) in the driver's seat.

LI–73

7.62 m (25 ft) or 3 m (9.84 ft)

E128200E01

2. PREPARATION FOR HEADLIGHT AIMING (Using a headlight aim test machine)

(a) Adjust the headlight aim in accordance with the

headlight aim test machine instructions.

3. PREPARATION FOR HEADLIGHT AIMING (for Using a Screen)

(a) Prepare the vehicle:

• Place the vehicle in a location that is dark enough to clearly observe the cutoff line. The cutoff line is a distinct line, below which light from the headlights can be observed and above which it cannot.

• Place the vehicle at a 90° angle to the wall.

• Create a 7.62 m (25 ft) distance between the vehicle (headlight bulb center) and the wall.

• Make sure that the vehicle is on a level surface.

• Bounce the vehicle up and down to settle the suspension.

NOTICE: A distance of 7.62 m (25 ft) between the vehicle (headlight bulb center) and the wall is necessary for proper aim adjustment. If sufficient space is not available, secure a distance of exactly 3 m (9.84 ft) to allow for checking and adjustment of headlight aim. (The size of the target zone will change with the distance, so follow the instructions in the illustration.)

(b) Prepare a piece of thick white paper (approximately

2 m (6.6 ft) (height) x 4 m (13.1 ft) (wid th)) to use as a screen.

(e) Draw base lines (H, V LH, and V RH lines) on the

screen as shown in the illustration. HINT:

• The base lines differ for "low-beam inspection" and "high-beam inspection".

• Mark the headlight bulb center marks on the screen. If the center mark cannot be observed on the headlight, use the center of the headlight bulb or the manufacturer's name marked on the headlight as the center mark.

(1) H Line (Headlight height):

Draw a horizontal line across the screen so that it passes through the center marks. The H line should be at the same height as the headlight bulb center marks of the low-beam headlights.

(2) V LH Line, V RH Line (Center mark position of

left-hand (LH) and right-hand (RH) headlights): Draw two vertical lines so that they intersect the H line at each center mark (aligned with the center of the low-beam headlight bulbs).

LIGHTING – HEADLIGHT ASSEMBLY

4. HEADLIGHT AIMING INSPECTION

(a) Cover the headlight or disconnect the connector of

the headlight on the opposite side to prevent light from the headlight that is not being inspected from affecting the headlight aiming inspection.

NOTICE: Do not keep the headlight covered for more than 3 minutes. The headlight lens is made of synthetic resin, which may melt or be damaged due to excessive heat.

HINT: When checking the aim of the high-beam, cover the low-beam or disconnect the connector.

(b) Start the engine.

Turn on the headlight and check if the cutoff line matches the preferred cutoff line in the following illustration.

5. HEADLIGHT AIMING ADJUSTMENT

(a) Adjust the aim vertically:

Adjust the headlight aim into the specified range by turning aiming screw with a screwdriver.

NOTICE: The final turn of the aiming screw should be made in the clockwise direction. If the screw is tightened excessively, loosen it and then retighten it, so that the final turn of the screw is in the clockwise direction.

HINT:

• The low-beam light and the high-beam light are a unit. Adjusting the aim on the low-beam to the correct position should also result in the highbeam adjustment being correct.

• If it is not possible to correctly adjust headlight aim, check bulb, headlight unit, and headlight unit reflector installation.

• The headlight aim moves up when turning the aiming screw clockwise, and moves down when turning the aiming screw counterclockwise.

ADJUSTMENT

HINT: It is possible that a bulb is incorrectly installed, affecting fog light aim. Bulb installation should be considered prior to performing the adjustment procedure.

1. VEHICLE PREPARATION FOR FOG LIGHT AIM

(a) Prepare the vehicle according to the following

conditions:

• Ensure there is no damage or deformation to the body around the fog lights.

• Fill the fuel tank.

• Make sure that the oil is filled to the specified level.

• Make sure that the coolant is filled to the specified level.

• Inflate the tires to the appropriate pressure.

• Unload the trunk and vehicle, ensuring that the spare tire, tools, and jack are in their original positions.

• Sit a person of average weight (68 kg, 150 lb) in the driver's seat.

• Vehicles with height adjustable suspension should set the vehicle height to the lowest setting prior to adjusting the fog light aim.

7.62 m (25 ft) or 3 m (9.84 ft)

E128202E01

2. PREPARATION FOR FOG LIGHT AIMING

(a) Prepare the vehicle:

• Place the vehicle in a location that is dark enough to clearly observe the cutoff line. The cutoff line is a distinct line, below which light from the fog lights can be observed and above which it cannot.

• Place the vehicle at a 90° angle to the wall.

• Create a 7.62 m (25 ft) distance between the vehicle (fog light bulb center) and the wall.

• Make sure that the vehicle is on a level surface.

• Bounce the vehicle up and down to settle the suspension.

NOTICE: A distance of 7.62 m (25 ft) between the vehicle (fog light bulb center) and the wall is necessary for proper aim adjustment. If unavailable, secure a distance of exactly 3 m (9.84 ft) for check and adjustment. (The t arget zone will change with the distance, so follow the instructions in the illustration.)

(b) Prepare a piece of thick white paper (approximately

2 m (6.6 ft) (height) x 4 m (13.1 ft) (wid th)) to use as a screen.

(e) Draw base lines (H, V LH, and V RH lines) on the

screen as shown in the illustration. HINT: Mark the fog light bulb center marks on the screen. If the center mark cannot be observed on the fog light, use the center of the fog light bulb or the manufacturer's name marked on the fog light as the center mark. (1) H Line (Fog light height):

Draw a horizontal line across the screen so that it passes through the center marks. The H line should be at the same height as the fog light bulb center marks of the low-beam fog lights.

(2) V LH Line, V RH Line (Center mark position of

left-hand (LH) and right-hand (RH) fog lights): Draw two vertical lines so that they intersect the H line at each center mark.

3. FOG LIGHT AIMING INSPECTION

(a) Cover the fog light or disconnect the connector of

the fog light on the opposite side to prevent light from the fog light that is not being inspected from affecting the fog light aiming inspection.

NOTICE: Do not keep the fog light covered for more than 3 minutes. The fog light lens is made of synthetic resin, which may melt or be damaged due to excessive heat.
