Headlamp Aiming - Buick 2008 Lucerne Owner's Manual

Headlamp Aiming

The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been preset at
the factory and should need no further adjustment.
However, if the vehicle is damaged in a crash, the aim
of the headlamps may be affected and adjustment
may be necessary.
If oncoming vehicles flash their high beams at you, this
may mean the vertical aim of your headlamps needs
to be adjusted.
It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need to be
adjusted. It is possible however, to re-aim the
headlamps as described.
The vehicle should:
•
Be placed so the headlamps are 25 ft. (7.6 m) from
a light colored wall.
•
Have all four tires on a level surface which is level
all the way to the wall.
•
Be placed so it is perpendicular to the wall.
•
Not have any snow, ice or mud on it.
•
Be fully assembled and all other work stopped while
headlamp aiming is being performed.
•
Be normally loaded with a full tank of fuel and one
person or 160 lbs (75 kg) sitting on the driver seat.
•
Have all tires properly inflated.
•
Have the spare tire is in its proper location in the
vehicle.
Headlamp aiming is done with the vehicle's low-beam
headlamps. The high-beam headlamps will be correctly
aimed if the low-beam headlamps are aimed properly.
