2008 Cadillac XLR Owner's Manual - Page 367

Headlamp Aiming 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 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 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. 6-47
