IF A TIRE GOES FLAT
It’s unusual for a tire to “blow out” while you’re driving, especially if you
maintain your tires properly. If air goes out
of a tire, it’s much more likely
to leak out slowly. But if you should ever have a “blowout,” here are a
few tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that pulls the vehicle
toward that side. Take your foot
off the accelerator pedal and grip the
steering wheel firmly. Steer to maintain lane position, then gently brake
to a stop well out
of the traffic lane.
A rear blowout, particularly on a curve, acts much like a skid and may
require the same correction you’d use
in a skid. In any rear blowout,
remove your foot from the accelerator pedal. Get the vehicle under
control by steering the way you want the vehicle to go.
It may be very
bumpy and noisy, but you can still steer. Gently brake
to a stop, well off
the road if possible.
If your tire goes flat, the next section shows how to use your jacking
equipment to change a flat tire safely.

If a tire goes flat, avoid further tire and wheel damage by driving slowly to
a level place. Turn on your hazard warning flasher.
A CAUTION:
Changing a tire can cause an injury. The vehicle can slip off the
jack and roll over you or other people. You and they could be
badly injured. Find a level place to change your tire. To help
prevent the vehicle from moving:
0 Put the shift lever in “P” (Park).
0 Set the parking brake firmly.
0 Turn off the engine.
To be even more sure the vehicle won’t move, you can put chocks
at the front and rear of the tire farthest away from the one being
changed. That would be the tire on the other side of the vehicle,
at the opposite end.

The following steps will tell you how to use the jack and change a tire.

An electric fan under the hood can start up and injure you even
when the engine is not running. Keep hands, clothing and tools
away from any underhood electric fan.

A CAUTION:
Things that burn can get on hot engine parts and start a fire.
These include liquids like gasoline, oil, coolant, brake fluid,
windshield washer and other fluids, and plastic or rubber. You
or others could be burned. Be careful not to drop or spill things
that will burn onto
a hot engine.
Before closing the hood,
be sure all the filler caps are on properly.
Then just pull the
hood down until it’s about 15 inches (38 cm) from
closing. Then close it firmly.
FLUID USAGE LABEL
Use the fluid usage label to identify the correct fluid you want to check.

Downloaded from www.Manualslib.com manuals search engine To check the fluid level:
0 Park your vehicle on a level place.
Place the shift lever in "P" (Park) with the parking brake applied.
With your foot on the brake pedal, move the shift lever through each
gear range, pausing for about three seconds in each range. Then,
position the shift lever in "P" (Park).
0 Let the engine run at idle for three to five minutes.
Then, without shutting
off the engine, follow these steps:
1. Pull out the dipstick and wipe it with a clean rag or paper towel.
2. Push it back in all the way, wait three seconds and then pull it back out
again.

Your brake master cylinder is here. It is filled with DOT-3 brake fluid.

There are only two reasons why the brake fluid level in your master
cylinder might
go down. The first is that the brake fluid goes down to an
acceptable level during normal brake lining wear. When new linings are

leaking out
of the brake system. If it is, you should have your brake
system fixed, since a leak means that sooner
or later your brakes won’t
work well, or won’t work at all.
So, it isn’t a good idea to “top off” your
brake fluid. Adding brake fluid won’t correct a leak.
If you add fluid when
your linings are worn, then you’ll have too much fluid when you get new
brake linings.
You should add (or remove) brake fluid, as necessary, only
when work is done on the brake hydraulic system.

If you have too much brake fluid, it can spill on the engine. The

When your brake fluid falls to a low level, your brake warning light will
come on. See “Brake System Warning Light” in the Index.
To Check Brake Fluid:
You can check the brake fluid without taking off the cap. If it’s low, fill it
to the maximum “FLUID LEVEC’ indicator.

When you do need brake fluid, use only DOT-3 brake fluid -- such as
Delco Supreme

sealed container only.
REPLACING BRAKE SYSTEM PARTS
The braking system on a modern vehicle is complex. Its many parts have
to be
of top quality and work well together if the vehicle is to have really
good braking. Vehicles
we design and test have top-quality GM brake
parts in them, as your Cadillac does when it is new. When you replace
parts of your braking system
-- for example, when your brake linings wear
down and you have to have new ones put in
-- be sure you get new
genuine
GM replacement parts. If you don't, your brakes may no longer
work properly. For example, if someone puts in brake linings that are
wrong for your vehicle, the balance between your front and rear brakes
can change, for the worse. The braking performance you've come to
expect can change in many other ways if someone puts in the wrong
replacement brake parts.

If you’re not going to drive your vehicle for 25 days or more, take off the
black, negative

from running down.
A CAUTION:
Batteries have acid that can burn you and gas that can explode.
You can be badly hurt if you aren’t careful. See LLJump Starting’’

Battery Power Loss

If you lose battery power or the battery is disconnected, your car’s
computer must be programmed. It takes just over 20 minutes
to do it. If
you want to do it yourself, here’s how:
Apply the parking brake.
Make sure the front wheels are straight.
Turn off the Electronic Climate Control.
