Headlamp Aim
Before making any headlamp adjustment, perform the following preparatory steps:
1. Remove ice or mud from under fenders.
2. Make sure all tires are inflated to recommended pressures.
3. Check springs for sag or broken leaves.
4. Take into consideration improper wheel alignment or improper tracking of the rear axle.
5. Make sure there is no load in the vehicle other than the fuel tank, one-half full.
6. Clean lenses and aiming pads.
7. Check for bulb burn-out and proper beam switching.
8. Make sure lamp output is well toward normal new lamp value.
9. Bounce the vehicle and allow to settle.
10. Make sure that the vehicle attitude is typical of how the vehicle is normally operated, i.e., with full load, carrying a trailer, etc.
Perform headlamp aim adjustments with Rotunda Headlamp Aiming Kit 107-00001 or equivalent. To aim the aerodynamically styled headlamps, the adjustable aimer adapters provided in the kit must be used. Adjustment aimer adapter positions are molded into the bottom edge of the headlamp lens.
Set and lock the adjustable adapters, attach each adapter to its mechanical aimer, and aim headlamps per latest instructions in the kit.
The equipment in Rotunda Headlamp Aiming Kit 107-00001 or equivalent can be calibrated to accommodate a slight slope in the floor, making it usable almost any place in the garage. However, area must be reasonably flat.
