## Headlamp Aiming Buick

Properly aim the headlamps in order to obtain the maximum road illumination and safety built into the headlamp system. Proper aiming is important with composite headlamps. Composite headlamps increase the range and the power of the headlamps. Slight variations from the recommended aiming may be hazardous to approaching motorists. Aiming after the bulb has been replaced is not required with composite headlamps.

Ensure that the vehicle is at the normal weight regarding the following items when you inspect the headlamp aim:

• | The fuel

• | The oil

• | The water

Inflate the tires uniformly to the specified pressure.

If the vehicle carries an unusual load in the rear compartment or a trailer, ensure that the load is on the vehicle when you inspect the headlamps.

Follow all of the individual state requirements for headlamp aiming.

Inspect the headlamp aim when installing a new headlamp assembly. Inspect the headlamp aim if service or repairs to the front end area may have disturbed the headlamps or the mountings.
