Headlamp Aiming - Chevrolet 2007 Cobalt Owner's Manual

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 flash 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.
•
The vehicle must have all four tires on a
perfectly level surface which is level all
the way to the wall.
•
The vehicle should be placed so it is
perpendicular to the wall.
•
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 done.
•
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs
(75 kg) on the driver's seat.
•
Tires should be properly inflated.
Headlamp aiming is done with the vehicle's
low-beam headlamps. The high-beam headlamps
will be correctly aimed if the low-beam headlamps
are aimed properly.
The vertical headlamp aiming screws are located
under the hood near the headlamps.
