(1.6 mm) or less of
tread remaining.
You need a new tire if:
ire.
0 You can see the indicators at three places around the t
You can see cord or fabric showing through the tire’s rubber.

Glass should be cleaned often. GM Glass Cleaner (GM Part No.
1050427) or a liquid household glass cleaner will remove normal tobacco
smoke and dust films.
Don’t use abrasive cleaners on glass, because they may cause scratches.
Avoid placing decals on the inside rear window, since they may have to be
scraped off later.
If abrasive cleaners are used on the inside of the rear
window, an electric defogger element may be damaged. Any temporary
license should not be attached across the defogger grid.
CLEANING THE OUTSIDE OF THE
WINDSHiELD AND WIPER BLADES
If the windshield is not clear after using the windshield washer, or if the
wiper blade chatters when running, wax or other material may be on the
blade or windshield.
Clean the outside
of the windshield with GM Windshield Cleaner,
Bon-Ami Powdera (GM Part
No. 1050011). The windshield is clean if
beads do not form when you rinse it with water.
Clean the blade by wiping vigorously with a cloth soaked in full strength
windshield washer solvent. Then rinse the blade with water.
Wiper blades should be checked on a regular basis and replaced when
worn.
CLEANING THE OUTSIDE OF YOUR
CADILLAC
The paint finish on your vehicle provides beauty, depth of color, gloss
retention and durability.
Washing Your Khicle
The best way to preserve your vehicle’s finish is to keep it clean by
washing it often with lukewarm or cold water.
Don’t wash your vehicle in the direct rays
of the sun. Don’t use strong
soaps or chemical detergents. Use liquid hand, dish or car washing

The headlight wiring is protected by a circuit breaker in the light switch.
An electrical overload
will cause the lights to go on and off, or in some
cases to remain off.
If this happens, have your headlight wiring checked
right away.
Windshield Wipers
r
The windshield wiper motor is protected by a circuit breaker and a fuse.
If the motor overheats due to heavy snow, etc., the wiper will stop until
the motor cools. If the overload is caused by some electrical problem and
not snow, etc.,
be sure to get it fixed.
I_
Power Windows and Other Power Options
Circuit breakers in the fuse panel 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.
