Toyota Tundra. Manual — part 2496

ADJUSTMENT

1. VEHICLE PREPARATION FOR HEADLIGHT AIM ADJUSTMENT

a. Prepare the vehicle:



Ensure that 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.



Place the spare tire, tools, and jack in their original positions.



Unload the trunk.



Have a person of average weight (68 kg, 149.9 lb) sit in the driver's seat.

2. PREPARATION FOR HEADLIGHT AIMING (Using a tester)

a. Prepare the vehicle for the headlight aim check.

b. Adjust in accordance with headlight tester instructions.

3. PREPARATION FOR HEADLIGHT AIMING (Using a screen)

a. Prepare the vehicle according to the following conditions:



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 (25.0 ft.) distance between the vehicle (headlight bulb center) and the wall.



Place the vehicle on a level surface.



Bounce the vehicle up and down to settle the suspension.

NOTE:

A distance of 7.62 m (25.0 ft.) between the vehicle (headlight bulb
center) and the wall is necessary for proper aim adjustment. If
unavailable, secure a distance of exactly 3 m (9.84 ft.) for the check
and adjustment. (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 (6.56 ft.) (height) x 4 m (13.1 ft.) (width))

to use as a screen.

c. Draw a vertical line down the center of the screen (V line).

d. Set the screen as shown in the illustration.

HINT:



Stand the screen perpendicular to the ground.



Align the V line on the screen with the center of the vehicle.

e. Draw base lines (H line, V LH, 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).

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 not being inspected from affecting headlight aiming inspection.

HINT:

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

b. Start the engine.

c. Turn on the headlight and make sure that the cutoff line falls within the specified area, as shown in

the illustration.

NOTE:



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



Do not cover the headlight with a black or dark colored material,
as such a material absorbs heat faster and this may melt the
lens.

HINT:



Since the low-beam light and the high-beam light are a unit, if the aim on one is correct, the
other should also be correct. However, check both beams just to make sure.



If the alignment distance is 7.62 m (25.0 ft.):

The cutoff line should be within 101 mm (3.97 in.) above or below the H line as well as 101
mm (3.97 in.) left or right of the V line with low-beam (SAEJ599).



If the alignment distance is 3 m (9.84 ft.):

The cutoff line should be within 40 mm (1.57 in.) above or below the H line as well as 40
mm (1.57 in.) left or right of the V line with low-beam (SAEJ599).



If the alignment distance is 7.62 m (25.0 ft.):

The high beam center of intensity should be within 101 mm (3.97 in.) above or below the H
line as well as 101 mm (3.97 in.) left or right of the V line. (SAEJ599).



If the alignment distance is 3 m (9.84 ft.):

The high beam center of intensity should be within 40 mm (1.57 in.) above or below the H
line as well as 40 mm (1.57 in.) left or right of the V line (SAEJ599).
