Proper road illumination and safety require headlamp aiming.
All states have requirements for headlamp aiming. Follow the state requirements.
Aim the headlamps with the low beam lamps. The high beam lamps aim correctly
if the low beam lamps are aimed properly.
Important: If the vehicle regularly carries an unusual load in the rear compartment
or if the vehicle regularly pulls a trailer, inspect the aim of the headlamps
with these specific loads on the vehicle.
- Ensure that the vehicle is at the normal weight with fuel, oil, water
and the spare tire.
- Ensure that the tires are uniformly inflated to the specified
pressure, refer to the
Tire Placard
in
General Information.
- Place the vehicle on a
level surface so that the headlamps are 7.6 m (25 ft) from a
wall or other flat surface (1).
- Locate the center line (1) on the aiming surface. The center
line of the aiming surface is in-line with the center of the vehicle.
4.1. | Mark the center of the front window with a narrow strip of masking

4.3. | Using the strips of masking tape, locate the center (1)
of the aiming surface through the center line of the vehicle. |
- Mark the horizontal center line of the headlamps (2) on
the flat surface directly in front of the vehicle.
- Measure from the floor to the horizontal center line on the headlamp (2).
- Measure from the center of the vehicle to center of the headlamp.
- Using this measurement, mark the vertical center lines of the
headlamps (5) on the aiming surface along the horizontal center line
of the headlamps (3).
- Turn the headlamps on low beam.
- Observe the low beam lamp pattern (3) on the aiming surface.
A correct pattern location is slightly below the horizontal center line (2)
and slightly to the right of the vertical center lines (5).
