Operation CHARM: Car repair manuals for everyone.

General Information

Aim the headlamp assemblies for proper illumination of the road. Verify the aim whenever you install a new headlamp assembly, or if service or repairs in the front end area may have disturbed the headlamp mounting brackets.

The screen method is preferred for aiming headlamps. If the headlamp is equipped with aiming pads, headlamp aiming may be performed using the alternate procedure.

Headlamp aiming is done with the low beam lamps. The high beam lamps will be correctly aimed if the low beam lamps are aimed properly. If the high beam needs adjustment, follow the screen method using the high beam bulb as the reference for measurements. Some state or provincial authorities have specific requirements for aiming the headlamps.
