Headlamp Vertical Aiming - Cadillac 2005 XLR Owner's Manual

•
The vehicle should be normally loaded with a full
tank of fuel and one person or 160 lbs (75 kg) on
the driver's seat.
•
Tires should be properly inflated.
•
Start the vehicle and rock it to level the suspension.
Headlamp aiming is done with the vehicle low beam
lamps. The high beam lamps will be correctly aimed if
the low beam lamps are aimed properly.
If you believe your headlamps need vertical (up/down)
adjustment, follow the vertical aiming procedure.
Adjustment screws can be turned with an E8 Torx
socket or T15 Torx screwdriver.
The headlamp aiming
devices are under the
hood near the headlamps.

Headlamp Vertical Aiming

Notice: Horizontal aiming must be performed
before making any adjustments to the vertical aim.
Adjusting the vertical aim first will result in an
incorrect headlamp aim.
1. Find the aim dot on the lens of the low beam lamps.
2. Measure the distance from the ground to the aim
dot on each low beam lamp. Record this distance.
3. At the wall or other flat surface, measure from the
ground upward the recorded distance from Step 2
and draw or tape a horizontal line the width of
the vehicle.
