Cadillac 2007 Automobile User Manual


 
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 flat surface.
The vehicle must have all four tires on a
level surface which is level all the way to
the wall or other flat surface.
The vehicle should be placed so it is
perpendicular to the wall or other flat 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 inflated.
The spare tire is in its proper location in
the vehicle.
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.
To adjust the vertical aim, do the following:
1. Open the hood. See Hood Release on
page 401 for more information.
2. Locate the center
of the projector lens
of the low-beam
headlamp.
3. Measure the distance from the ground to the
center of the projector lens of the low-beam
headlamp. Record the distance.
