Preliminary Checks

s2 dm 18.01.000

Before checking or adjusting the headlight aim, do the following:

Check that the hood is closed and latched.
Check the suspension for proper functioning of the leveling mechanism. On vehicles with air suspensions, make sure that the height is properly adjusted.
Remove any large amounts of mud or ice from the underside of the fenders.
Check the springs for sagging or broken leaves.
Check for damage to the hood and hinge assembly. Repair as necessary.
Clean the headlight lenses. Use a soft cloth with mild, non-caustic soap or detergent, and water.
With the vehicle unloaded, check that the tires are inflated to the recommended air pressure.
