wipers on. Position the wipers on the windshield in
the
“mid” wipe position. Then with the door open,
turn the ignition to
OFF.
2. Insert a screwdriver into the slot as shown and press
down to release the wiper blade assembly.
3. Align the wiper arm pin with the hole on the wiper
blade assembly and snap it into place to install.
Headlamp Aiming
Your vehicle has the composite 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 dealer.
Headlamps on damaged vehicles may require
recalibration of the horizontal aim by your dealer.
To check the aim, the vehicle should be properly
prepared as follows:
Place the vehicle on a level pad or surface.
The vehicle should not have any snow, ice or mud
The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.

vehicle, except it should have a full tank of gas and
one person or 160 lbs. (75 kg) on the driver’s seat.
Tires should be properly inflated.
0 Rock the vehicle to stabilize the suspension.
NOTICE:
L
To make sure your headlamps are aimed
properly, read all the instructions before
beginning. Failure to follow these instructions could cause damage to headlamp parts.
For the vertical adjustment, state inspection stations
generally will allow a reading of plus 0.76 degrees or
minus 0.76 degrees from the center of the bubble.
It is recommended that the upper limit not exceed plus
0.4 degrees from the center of the bubble. Other drivers
may flash their high beams at you if your adjustment
is
much above plus 0.4 degrees. If you
find that the headlamp aiming needs adjustment,
follow these steps:
..

1. Start by opening the hood and locating the vertical
and horizontal aim indicators. The aiming screw for
the horizontal aim indicator is on the outboard side
of the headlamp cover and the aiming screw for the
vertical aim indicator is on the inboard side.

that your vehicle needs to be on a level surface. Turn
the vertical aiming screw until the bubble inside the
level is centered at
“0.”
3. After the vertical aim is correct, check the horizontal
aim for each headlamp and adjust as necessary. Turn
the horizontal aiming screw until the end of the
screw aligns with the

Downloaded from www.Manualslib.com manuals search engine Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded.
If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced. If the
wheel leaks
air, replace it (except some aluminum
wheels, which can sometimes be’repaired). See your
dealer
if any of these conditions exist.
Your dealer
will know the kind of wheel you need.
Each
new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new
GM original
equipment parts.
This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your Cadillac model.
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous.
It could affect the braking and
handling
of your vehicle, make your tires lose
air and make you lose control. You could have a
collision in which you or others
could be injured.
Always use the correct wheel, wheel bolts and
wheel nuts
for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer
or
-odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for
more information.

Downloaded from www.Manualslib.com manuals search engine 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 fmed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load
is too heavy,
the cifcuit breaker opens and closes, protecting the circuit until the problem
is fixed or goes away.
MaxiFusesLRelay Center
The MaxiFuses and relays are located next to the engine
compartment fuse b1oc.k on the driver’s side
of the
engine.
To access the compartment fuse block, remove
the shroud cover.
If a MaxiFuse should blow, have your
vehicle serviced by your dealer immediately.
