Headlight - Adjustment / General Information
Headlight Bulb Replacement
Warning; Halogen bulbs are gas-filled and under pressure and may shatter if the suface is scratched or the bulb is dropped. Wear eye protection and handle the bulbs carefully, grasping only the base whenever possible. Don't touch the surface of the bulb with your fingers because the oil from your skin could cause it to overheat and fail prematurely. If you do touch the bulb surface, clean it with rubbing alcohol.
1. Disconnect the negative cable from the battery.
2. Reach behind the headlight assembly and disconnect the electrical connector. If you are unable to access the rear of the headlight remove the housing assembly.
3. Rotate the lockring or the bulb socket counterclockwise and remove the bulb holder from the headlight housing.
4. Insert the new bulb into the holder, secure it into the housing with the lockring and connect the electrical connector.
Headlight - Adjustment
Warning; The headlights must be aimed correctly. If adjusted incorrectly, they could temporarily blind the driver of an oncoming vehicle and cause an accident or seriously reduce your ability to see the road. The headlights should be checked for proper aim every 12 months and any time a new headlight is installed or front-end bodywork is performed. The following procedure is only an interim step to provide temporary adjustment until the headlights can be adjusted by a properly equipped shop.
1. Headlights have two spring loaded adjusting screws, located at the rear of the housing. The outer adjuster controls up-and-down movement and the inner adjuster controls left and-right movement. Note:On 2001 and later models, there is only one adjuster screw, for the vertical adjustment.
2. There are several methods of adjusting the headlights. The simplest method requires an open area with a blank wall and a level floor.
3. Position masking tape vertically on the wall in reference to the vehicle centerline and the centerlines of both headlights.
4. Position a horizontal tapeline in reference to the centerline of all the headlights Note:It will be easier to position the tape on the wall with the vehicle parked only a few inches away.
5. Adjustment should be made with the vehicle parked 25 feel from the wall, sitting level, the gas tank half-full and no unusually heavy load in the vehicle.
6. Starting with the low beam adjustment, position the high intensity zone so it is two inches below the horizontal line and two inches to the side of the vertical headlight line away from oncoming traffic. Twist the adjustment screws until the desired level has been achieved.
7. With the high beams on, the high intensity zone should be vertically centered with the exact center just below the horizontal line. Note: It may not be possible to position the headlight aim exactly for both high and low beams. If a compromise must be made, keep n mind that the low beams are the most used and have the greatest effect on driver safety.
