Headlamp Aiming - Buick Automobile User Manual

Headlamp Aiming

The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory and
should need no further adjustment
However, if the vehicle is damaged in a crash, the
headlamp aim may be affected and adjustment may be
necessary.
If oncoming vehicles flash their high beams at you, this
may also mean the vertical aim needs to be adjusted.
It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need to be
re-aimed. 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 perfectly 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 done.
•
Be normally loaded with a full tank of fuel and one
person or 160 lbs (75 kg) on the driver seat.
•
Have all tires properly inflated.
5-56
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.
Locate the vertical headlamp aiming screws under
the hood near the headlamps.
The adjustment screw can be turned with a 6 mm
male hex.
