2006 HUMMER H3 high beam

Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory and
should need no further adjustment.
However, if the vehicle is damaged in an accident,
the headlamp aim may be affected and adjustment may
be necessary.
If oncoming vehicles ash their high beams at you, this
may also mean the vertical aim needs to be adjusted.
It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be re-aimed.
It is possible however, to re-aim the headlamps as
described in the following procedure.The vehicle should be properly prepared as follows:The vehicle should be placed so the headlamps
are 25 ft. (7.6 m) from a light colored wall or
other at surface.
The vehicle must have all four tires on a level
surface which is level all the way to the wall or
other at surface.
The vehicle should be placed so it is perpendicular
to the wall or other at surface.
The vehicle should not have any snow, ice,
or mud on it.
The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being
performed.
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs (75 kg)
sitting on the driver’s seat.
Tires should be properly inated.
The spare tire is in its original location in the vehicle.
