Headlamp Aiming
The headlamp aiming system has been preset at the factory.
If the vehicle is damaged in an accident, the aim of the headlamps can be affected and adjustment could be necessary.
It is recommended that a dealer adjust the headlamps. To re-aim the headlamps yourself, use the following procedure.
The vehicle should be properly prepared as follows:
The vehicle should be placed so the headlamps are 7.6 m (25 ft) from a light-colored wall.
The vehicle must have all four tires on a level surface which is level all the way to the wall.
The vehicle should be placed so it is perpendicular to the wall.
The vehicle should not have any snow, ice, or mud on it.
The vehicle should be fully assembled and all other work stopped while headlamp aiming is being performed.
The vehicle should be normally loaded with a full tank of fuel and one person or 75 kg (160 lbs) sitting on the
driver seat.
Tires should be properly inflated.
Headlamp aiming is done with the vehicle's low-beam headlamps. The high-beam headlamps will be correctly aimed if
the low-beam headlamps are aimed properly.
To adjust the vertical aim:
1. Open the hood. See Hood for more information.

2. Locate the aim point at the center inner projector condensing lens of the low-beam headlamp, not the outer
lens.
3. Measure the distance from the ground to the aim dot on the low-beam headlamp. Record the distance.
4. At the wall, measure from the ground upward (A) to the recorded distance from Step 3 and mark it.
5. Draw or tape a horizontal line (B) on the wall the width of the vehicle at the height of the mark in Step 4.
Notice: Do not cover a headlamp to improve beam cut-off when aiming. Covering a headlamp may cause
excessive heat build-up which may cause damage to the headlamp.
6. Turn on the low-beam headlamps and place a piece of cardboard or equivalent in front of the headlamp not
being adjusted. This allows only the beam of light from the headlamp being adjusted to be seen on the flat
surface.
7. Locate the vertical headlamp adjusters, which are under the hood near each headlamp assembly.
For the vehicle equipped with a base level lamp (halogen bulb), there will be one vertical headlamp adjuster
(V1).
For the vehicle equipped with an up-level headlamp (HID), there will be two vertical headlamp adjusters for V1
and V2 (A).

Some vehicles have funnel-shaped caps on the adjusters for easier access of a Number 2 Phillips screwdriver
to turn the adjusters.
8. For the base vehicle, turn the vertical adjuster (V1) until the headlamp beam is aimed to the horizontal tape
line. Turn it clockwise or counterclockwise to raise or lower the angle of the beam.
For the up-level vehicle, turn the vertical adjusters (V1 and V2) simultaneously until the headlamp beam is
aimed to the horizontal tape line. Turn them clockwise or counterclockwise to raise or lower the angle of the
beam.
9. Make sure that the light from the headlamp is positioned at the bottom edge of the horizontal tape line. The
lamp on the left (A) shows the correct headlamp aim. The lamp on the right (B) shows the incorrect headlamp
aim.
10. Repeat Steps 7–9 for the opposite headlamp.
