GMC JIMMY 1997 Owner's Manual

Brake Pedal Travel
See your dealer if the brake pedal does not return to
nor~nal height, or
if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
If your brake pedal goes down farther than normal. your
rear drum brakes may need adjustment. Adjust them
by
backing up and firmly app1yin.g the brakes a lew times.
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.
Your vehicle was designed and tested
with top-quality
GM brake parts. When
you replace parts of your braking system
-- for
example, when your brake linings wear down and you
haw to have new ones
put in -- be sure you get new
approved
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.
Battery
Every new vehicle has a Delco Freedom@ battery. You
never have to add water to one of these. When it’s time
for a new battery, we recomlnend a Delco Freedom
battery. Get one that has the replacement number shown
on the original battery‘s label.

Overloading your tires can cause
overheating
as a result of too much friction.
You could have an air-out and a serious
accident. See “1,oading 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.
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.
Inflation -- Tire Pressure
The Cel-tification/Tire label. which is 011 the driver‘s
door edge, above the door latch. shows the correct
inflation
pressures for your tires when they’re cold.
“Cold“ lneans 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
0 Tire overloading
Bad wear
0 Bad handling
0 Bad fuel economy.
