Cadillac 2006 XLR, Owner'S Manual

Page: 360 / 448

Headlamp aiming is done with the low-beam headlamps.
The high-beam headlamps will be correctly aimed if
the low-beam headlamps are aimed properly.
The headlamp aiming
devices are under the
hood near the headlamps.
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.
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
headlamp.
2. Measure the distance from the ground to the aim
dot on each low-beam headlamp. 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.
