.
The surge tank is located next to the engine block on the
passenger’s side of the engine.
The cooling system when hot is under a lot of pressure.
If the CHECK COOLANT LEVEL message appears on
the
DIC, you will’need to add coolant.
A CAUTION:
I’urning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly. Never turn the surge tank pressure cap
-- even a
little
-- when the engine and radiator are hot.
When your engine is cold, the coolant level should be
at the full cold mark, which is 2.5 inches (60 mm) below
the
base of the fill neck. Use a flashlight as necessary to
see into the tank.

When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and look at the fluid level on the dipstick.
The level should be at the
FULL COLD mark. If
necessary, add only enough fluid to bring the level up to
the mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid to use. See “Recommended Fluids and
Lubricants” in the Maintenance Schedule booklet.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle
in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.

We don’t make tires. Your new Cadillac 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.
A 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 “Loading Your Vehicle’’ in
the Index.
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.
CAUTION: (Continued)
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.
See “Inflation
-- Tire Pressure’’ in this section
for inflation pressure adjustment for higher
speed driving.
Inflation -- Tire Pressure
The Tire-Loading Information 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.
“Cold” means your vehicle has been sitting for at least
three hours or driven no more
than a mile.
If you’ll be driving at speeds higher than
100 mph
(160 km/h) where it is legal, raise the cold inflation
pressure
of each tire to 35 psi (240 Wa). When you end
this very high-speed driving, reduce the cold inflation

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.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Needless damage from road hazards.
i Rough ride
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be
at
60 psi (420 Wa).
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.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 OOO to 13 000 km) for any signs of unusual wear.
If unusual wear is present, rotate your tires as soon
as
possible and check wheel alignment. Also check for
damaged tires
or wheels. See “When It’s Time for New
Tires” and “Wheel Replacement” later
in this section for
more information.

When It’s Time for New Tires
One way to tell when it’s
1 A time for-new tires is to
check the treadwear indicators,
which will
appear when
your tires have
only 1/16 inch (1.6 mm) or
less
of tread remaining.
+- You need a new tire if any of the following statements
are true:
c
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the

tire’s rubber.
enough
to show cord or fabric.
0 The tire has a bump, bulge
or split.
0 The tire has a puncture, cut or other damage that
can’t be repaired
well because of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification
(TPC Spec)
number on each tire’s sidewall. When you get new tires, get ones with that same
TPC Spec number. That way
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on your vehicle.
If your tires have an all-season tread
design, the TPC number will be followed
by an “MS”
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.

Downloaded from www.Manualslib.com manuals search engine Care of Safety Belts
Keep belts clean and dry.
I A CAUTION:
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In
a crash they might
not be able
to provide adequate protection.
Clean safety belts only with mild soap and
lukewarm water.
Glass
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 Powder@ (GM Part
No. 105001 1). 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.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply silicone
grease with a clean cloth at least every
six months.
During very cold, damp weather more frequent
application may
be required. (See “Recommended
Fluids and Lubricants”
in the Maintenance Schedule
booklet.)

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. Some add-on electrical equipment
can keep other components from working
as
they should.
Your vehicle has an air bag system. Before attempting to
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.

Downloaded from www.Manualslib.com manuals search engine Plan Ahead When Possible
Whenever possible, schedule an appointment for your
vehicle’s warranty work. Your Cadillac dealer can then
prepare
to meet your alternative transportation needs
and minimize inconveniences typically associated with
warranty repairs.
Owner Responsibilities
There are only two things which you will be responsible
for during the use
of your courtesy vehicle. You are
required to provide insurance coverage and replenish the
fuel used.
In many cases your own auto insurance policy may
provide primary coverage for the courtesy vehicle, similar to rental car agreements. Please, check
with your
insurance company to be certain what’s covered.
This service is provided to
you under the terms of the
New Vehicle Warranty, therefore, it is imperative that
your vehicle 6e picked up from the dealership at the
completion
of the warranty service. Vehicles not picked
up in a timely fashion may incur rental fees charged to
the customer.
