How to adjust standard headlight aim?


Recommended Posts

How do you adjust the aim of the front headlights? According to the owner's manual, the adjustment screw is behind the rearmost rubber cover behind the trunk siding, but I can't find the screw on my car.

Your car should have one or two rubber plugs closest to the driver. If there are two then the top one is for lateral adjustment and bottom one is vertical adjustment (up and down). If your car only has one then it will only have vertical adjustment.

Use a 5mm ball end allen wrench since the adjusters don't always line up very well with the opening.

Thanks Loren. The adjuster isn't lined up very well with the rubber plug on my car, so I decided to pop the whole headlight assembly out of the fender, using the special tool included in the tool box. This was a good idea, as doing so gave me easy access to all three adjusters, those for the headlight as well as the fog light.

Here is a followup to my prior post. Popping out the headlight really is the easy way to do the re-aiming. The headlight assembly unlocks, slides out and back in and then relocks securely very easily.

Turning the bottom rearmost adjuster one full revolution results in about a 5cm change in beam height at the standard 7.5m viewing distance, per owner's manual. However, to raise the beam you have to turn the adjuster clockwise, opposite to what the manual states.
