2. Measure the distance from the ground to the aim dot
on each low beam lamp. Record this distance.3. At the wall or other flat surface, measure from the
ground upward the recorded distance from Step 2
and draw or tape a horizontal line the width of
the vehicle.

4. Turn on the low-beam headlamps and place a piece
of cardboard or equivalent in front of the headlamp
not being aimed. This should allow only the beam of
light from the headlamp being aimed to be seen on
the flat surface.
NOTICE:
Do not cover a headlamp to improve beam
cut
-off when aiming. Covering a headlamp may
cause excessive heat build
-up which may cause
damage to the headlamp.
5. Turn the vertical aiming screw (V) until the headlamp
beam is aimed to the horizontal tape line. The top edge
of the cut
-off should be positioned at the bottom edge
of the horizontal tape line.
6. Repeat Steps 4 and 5 for the opposite headlamp.

described previously.
2. Remove the rubber, circular

affected bulb from the headlamp assembly.
3. Press the locking release lever, turn the bulb
socket counterclockwise and remove it from the
headlamp assembly. (There is no lock for the
sidemarker lamp.)
4. Remove the old bulb from the bulb socket.
5. Put the new bulb into the bulb socket.
6. Put the bulb socket into the turn signal housing and
turn it clockwise until it locks. Use care not to touch
the bulb with your fingers or hands. (There is no lock
for the sidemarker lamp.)
7. Reinstall the rubber, circular
-shaped bulb cap to the
headlamp assembly.
8. Put the headlamp assembly back into the vehicle by
reversing the previous mentioned steps.

4. Pull the bulb straight out
from the socket.
5. Press a new bulb into the socket, insert it into the
taillamp housing and turn the socket clockwise into
the taillamp housing until it clicks. (The sidemarker
lamp does not have a release tab and therefore will
not click when it is installed.)
6. Reinstall the rear lamp assembly and tighten
the screws.

Windshield Wiper Blade Replacement
Windshield wiper blades should be inspected at least
twice a year for wear and cracking. See ªWiper Blade
Checkº in the Index for more information.Replacement blades come in different types and
are removed in different ways. For proper type and
length, see ªNormal Maintenance Replacement Partsº
in the Index.
To replace the windshield wiper blade assembly do
the following:
1. Lift the wiper arm and turn the blade until it is facing
away from the windshield.
2. Push the release lever and slide the wiper assembly
toward the driver's side of the vehicle.
3. Install a new blade by reversing Steps 1 and 2.

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service, see
your Cadillac Warranty booklet for details.
CAUTION:
Poorly maintained and improperly used tires
are dangerous.
Overloading your tires can cause overheating
as a result of too much friction. You could
have an air
-out and a serious accident.
See ªLoading Your Vehicleº in the Index.
CAUTION: (Continued)
CAUTION: (Continued)
Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.

6-50 Inflation -- Tire Pressure
The Certification/Tire label, which is located on the rear
edge of the driver's door, shows the correct inflation
pressures for your tires when they're cold. ªColdº
means your vehicle has been sitting for at least
three hours or driven no more than 1 mile (1.6 km).
NOTICE:
Don't let anyone tell you that underinflation or
overinflation is all right. It's not. If your tires
don't have enough air (underinflation), you can
get the following:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy
NOTICE: (Continued)
NOTICE: (Continued)
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards
When to Check
Check your tires once a month or more. Also, check the
tire pressure of the spare tire.
How to Check
Use a good quality pocket
-type gage to check tire
pressure. You can't tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they're underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.

6-51 Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See ªWhen It's Time for New Tiresº and
ªWheel Replacementº later in this section for more
information. Make sure the spare tire is stored securely.
Push, pull, and then try to rotate or turn the tire. If it
moves, use the wheel wrench to tighten the cable. See
ªStoring a Flat or Spare Tire and Toolsº in the Index.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See ªScheduled
Maintenance Servicesº in the Index for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here. Don't include the spare tire in your
tire rotation.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the
Certification/Tire label. Make certain that all wheel nuts
are properly tightened. See ªWheel Nut Torqueº in
the Index.
