Headlamp Aiming - Cadillac 2008 XLR Owner's Manual

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 you suspect that
the headlamps need to be reaimed, it is recommended
that you contact your dealer/retailer for service.
However, it is possible for you to re-aim your headlamps
as described in the following procedure.
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 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 and 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.
•
Tires should be properly inflated.
•
Start the vehicle and rock it to level the suspension.
