Headlamp Aiming
The optical headlamp aiming system has been preset at
the factory and should need no further adjustment
However, If the vehicle is damaged, the headlamp aim
may be affected and adjustment may be necessary.
If oncoming vehicles flash their high beams at you, this
may also mean the vertical aim needs to be adjusted.
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.
The vehicle should be:
Placed so the headlamps are 25 ft. (7.6 m) from a
light colored wall.
On a perfectly level surface which is level all the
way to the wall.
Placed so it is at a right angle to the wall.
Clear of any snow, ice, or mud on it.
Fully assembled, with the tires properly inflated, and
all other work stopped while headlamp aiming is
being done.
Normally loaded with a full tank of fuel, with the
spare tire in the proper location, and one person
or 160 lbs (75 kg) on the driver seat.
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 on the headlamps:
1. Open the hood. See Hood Release on page 5-11.
2. Record the distance from the ground to the aim dot
on the low-beam headlamp.
