How to Adjust a Mercedes' Headlights

In the U.S. the type, adjustments, and illumination factors of all automobile lighting devices are regulated by the Federal Motor Vehicle Safety Standard 108. The headlights must function and be adjusted correctly. Your high beams must disperse their beams straight forward and low beams down and to the right while safely providing illumination without too much or too little glare. It is wise to check the headlight adjustment on your Mercedes at least every year. Doing it yourself will save you time and money. It will also make driving safer for you and others you may meet on the road at night. All it takes is time, some basic tools and a little patience.

Show More Instructions

1. • 1 Open the hood and prop it up.
     
   • 2 Remove components if necessary to allow access to the left/right and up/down adjustment knobs. They are on top of the rear side of the headlight. The upper knob adjusts the beam to the left and right. The lower knob controls up/down adjustments.
     
   • 3 Park with the passenger side of the car parallel to a solid fence or wall and about four feet from it. When there is dim light or darkness, turn on the lights and use your screwdriver to adjust the up/down knob on the passenger-side headlight until the light beam is parallel to the ground (you can see the beam of light against the surface of the wall).
     
   • 4 Turn the car so that it faces the wall approximately one car length away. Adjust the up/down knob on the driver-side headlight until it is at the same level as the passenger side headlight. Then adjust both sides until the small groove on top of the beam cutoff is directly in front of the light.
     
   • 5 Reinstall any components that you removed. Close the hood.
     

Tips & Warnings

• This is method is generic for Mercedes models. Some may differ, as there are many models out there.

It is best to have a dealership mechanic, or a mechanic do this. However, there are (on most models) screw that you turn to adjust each side of each light. If you kneal down and look above, and beside the headlight (inside toward grill) you'll see these. It is best to do this at night, and against a dark wall or object about 50-100 feet back. Each light will need to point downward, and inward coming together (merging in the center).
Please let me know if you need further assistance.

you should try to adjust with the adjustment screw on the side of the light

First check bulb is inserted and clipped in correctly most are awkward.did the inner part get disturbed etc.i dont know if ur model has auto adjust headlights but even if it does and the motors failed they can still be done manually.most have two nut shaped adjusters or take hex type key .i think u should check the stuff i started with.they dont just go out of adjustment without a cause

I posted the adjustment directions here.

I had a similar problem on my 04 expedition. I just bought it and the headlights were aiming too far down. A rather larger gap was noticeable between the headlight and the hood. The so called adjustment bolt did nothing. I removed the headlights and found 2 issues. On the adjustment bolt there is a washer. Make sure when you re-install the headlight the washer sets on top of the plastic slot and is visible when looking down behind the headlight. Without the washer being in the correct location it will not tighten the headlight in place.
Second I found the adjustment bolt adjusted nothing. It merely tightened the headlight in place. What I had to do was to loosen this bolt and physically move the headlight into place and the re-tighten the bolt. Hence the slot is the adjustment. Turning the bolt CW or CCW did not move the headlight.
I tried several things trying to figure why the lights would not move until I realized I could move the light with my hands and tightened them in place using the adjustment bolt.

This may not be your issue but I found the owners manual instructions to be useless.

Further to Emmisionwiz's answer that worked for me - the holes are in the black plastic covering the radiator support, to each side more or less in line with the headlights. They are marked with an "A" and rotation directions for UP and DOWN. The Phillips screwdriver goes into the hole about 45 degrees from vertical and engages the adjusting rack, where the teeth of the Phillips screwdriver are the pinion. If you shine a flashlight down the hole you can see the rack teeth and all becomes clear. But you will need a long Phillips screwdriver and a little bit of luck.

In the owner's manual it says the lights are adjusted correctly at the dealership and if they need adjustment because of a trailer then take the car to a Honda certified mechanic.

I have a 2004 Accord also and the method is the same for that one too.
