Headlamp Aiming
The vehicle has a visual optical headlamp aimingsystem. The aim of the headlamps have been preset atthe factory and should need no further adjustment.
However, if the vehicle is damaged in a crash, the aimof the headlamps may be affected and adjustment maybe necessary.
If oncoming vehicles flash their high beams at you, thismay mean the vertical aim of your headlamps needs tobe adjusted.
It is recommended that the vehicle is taken to yourdealer/retailer for service if the headlamps need to beadjusted. It is possible however, to re-aim theheadlamps as described.
The vehicle should:
.Be placed so the headlamps are 25 ft. (7.6 m) froma light colored wall or other flat surface.
.Have all four tires on a level surface which is levelall the way to the wall or other flat surface.
.Be placed so it is perpendicular to the wall or otherflat surface.
.Not have any snow, ice, or mud on it.
.Be fully assembled and all other work stoppedwhile headlamp aiming is being performed.
.Be normally loaded with a full tank of fuel and oneperson or 160 lbs (75 kg) sitting on the driver seat.
.Have the tires properly inflated.
.Have the spare tire is in its proper location in thevehicle.
Headlamp aiming is done with the vehicle's low-beamheadlamps. The high-beam headlamps will be correctlyaimed if the low-beam headlamps are aimed properly.
To adjust the vertical aim:
1. Open the hood. SeeHood Releaseon page 7!15for more information.
2. Locate the center ofthe projector lens ofthe low!beamheadlamp.
3. Record the distance from the ground to the centerof the projector lens of the low!beam headlamp.
