Headlamp Aiming
Your vehicle has the 55 x 135 mini-quad headlamp
system. These headlamps have horizontal and vertical
aim indicators. The aim has been pre-set at the factory
and should need
no further adjustment.
If your vehicle is damaged in an accident and the
headlamp aim seems to be affected, see your
Cadillac dealer. Headlamps
on damaged vehicles
may require recalibration of the horizontal aim by
your Cadillac dealer.
To check the aim, the vehicle should be properly
prepared as follows:
The vehicle must have all four tires on a perfectly
level surface.
The vehicle should not have any snow, ice or mud
attached to it.
0 There should not be any cargo or loading of the
vehicle, except it should have a full tank of gas and
one person or
160 lbs. (75 kg) on the driver’s seat.
0 Tires should be properly inflated.
The horizontal indicator should read “0.”

Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your Cadillac
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and
the damage wouldn’t be covered by your warranty.

add anything electrical to your Cadillac, see “Servicing
Your Air Bag-Equipped Cadillac” in the Index.
Headlamp Wiring
The headlamp wiring has an individual fuse which is
powered by a MaxiFuse@. An electrical overload will
cause the lamps to
go on and off, or in some cases to
remain off. If this happens, have the headlamp wiring
checked right away.
MaxiFuse
is a registered trademark of Little
Fuse Incorporated.
Windshield Wiper Fuses
The windshield wiper motor is powered by a MaxiFuse.
If
the motor overheats due to heavy snow, etc., the
wipers will stop until the motor cools. If the overload
is caused by some electrical problem, be
sure to have
it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.
