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.

Comments

I read over the recalls and they do have recalls on brake and turn signal lights but not the low beam headlights while driving at night.

Sounds like the relay or headlamp driver module relay 46, for the headlights is going bad, though.
Or, it could alternatively be bad grounding of wire somewhere or bad wiring in general.

I would check in the underhood fuse box for the relay and see if wiggling it to ensure a good connection helps matters.

I have a similar problem with my 55 plate 93.
I go to Halfords and by a pair of H7s (two for one offer, replace BOTH at the same time and keep the old 'good' bulb as a get out of jail.

No one seems to know what the answer is.. or do they?

There are two adjustment points (screws). For example left headlight: you will see one point near the end of left wing, at bottom side through a wing hole. This is for vertical plane headlight beam adjustment (up-down). Another one point is against water radiator side. This is for horizontal plane headlight beam adjustment (left-right).

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.

Might as well check the orange headlight control unit first, as it is an extremely common issue, and will only take you 20 minutes. Here is a step by step tutorial with pictures to examine and repair it. The tutorial is from a 1995 900 but is fully applicable to your car.

How do I replace the left Xenon low beam bulb on my 2007 9-3 4dr 2.0 turbo SAAB?. The battery box , fuse box and windshield washer resivour practically a **** upto the back of the bulb area.
Do I have to remove the entire headlight assembly? if so will that ruin the auto light adjustment for the lowbeam.

there is this product called beam benders that fit on the headlight, that with change the beam.

IF THE BULBS ARE OK CHECK THE HEADLIGHT MODULE(IT LOOKS LIKE A RELAY, ORANGE CASE I THINK) TRY WIGGLING IT,IM PRETTY SURE THATS IT. THEY GO BAD ALOT ON SAABS. IT SHOULD BE IN THE ENGINE CONPARTMENT
