It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need
to be re-aimed. It is possible however, to re-aim the
headlamps as described.
Notice: To make sure your headlamps are aimed
properly, read all the instructions before beginning.
Failure to follow these instructions could cause
damage to headlamp parts.
The vehicle should:
•
Be placed so the headlamps are 25 ft. (7.6 m) from
a light colored wall.
•
Have all four tires on a level surface which is level
all the way to the wall.
•
Be placed so it is perpendicular to the wall.
•
Not have any snow, ice, or mud on it.
•

headlamp aiming is being performed.
•
Be normally loaded with a full tank of fuel and one
person or 160 lbs (75 kg) sitting on the driver seat.
•

headlamps. The high-beam headlamps will be correctly
aimed if the low-beam headlamps are aimed properly.

1. Open the hood. See Hood Release on page 5-11
for more information.
2. Find the center line running through the lens of
the headlamp.
3. Record the distance from the ground to the center
