Headlamp Aiming
The high intensity discharge (HID) visual optical aiming
type headlamps have been preset at the factory and
should need no further adjustment. If the headlamps
need to be re-aimed, it is recommended to see your
dealer/retailer for service. However, it is possible to
re-aim the headlamps as described in the following
procedure.
Notice:To make sure the 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 properly prepared as follows:
The vehicle should be placed so the headlamps are
25 ft (7.6 m) from a light colored wall.
The vehicle must have all four tires on a perfectly
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
attached to it.
The vehicle should be fully assembled all other
work stopped while headlamp aiming is being done.
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs (75 kg) on
the driver seat.
The tires should be properly in ated.
Start the vehicle and rock it to level the suspension.
Headlamp aiming is done with the low-beam
headlamps. The high-beam headlamps are correctly
aimed if the low-beam headlamps are aimed properly.
The headlamp aiming
device is under the hood
near the headlamps.
