How To Use This Manual
Safety Warnings and Symbols
You will find a number of safety cautions in this book. We use y\
ellow and
the word
CAUTION to tell you about things that could hurt you if you were to
ignore the warning.
These mean there is something that could hurt you
or other people.
In the yellow caution area, we tell you what the hazard
is. Then we tell you
what to
do to help avoid or reduce the hazard. Please read these cautions. If
you don’t, you or others could be hurt.
You will also find a red circle with
a slash through it in this book. This safety
symbol means “Don’t,’’ “Don’t
do this,” or “Don’t let this happen.”

Vehicle Damage Warnings
Also, in this book you will find these blue notices:
I
?se mean there is something that could damage your vehicle.
In the blue notice area, we tell you about something that can damage your
vehicle. Many times, this damage would not be covered by your \
warranty, and
it could be costly. But the notice will tell you what to
do to help avoid the
damage.
When you read other manuals, you might see CAUTION and NOTICE \
warnings in different colors or in different words. In this manual, we’ve used
the familiar words and colors that General Motors has used for\
years.
You’ll also see warning labels on your vehicle. They use th\
e same colors, and the words CAUTION
or NOTICE.

Brake System. Warning Light
BRAKE
. , K2325
Your vehicle’s hydraulic brake system is divided into two parts. If ,one‘ part
isn’t working, the other part can still work and stop you. \
For good braking,
though, you need both- systems working well.
Your vehicle also has rear-wheel antilock brakes.
If the warning light goes on,
there could be a brake problem with either your regular or rear wheel antilock
brakes, or both. Have your brake system inspected right away.
This light should come on as you start the vehicle.
If it doesn’t come on
then, have
it fixed so it will be ready to warn you if there’s a problem.
This light
will also come on when you set your parking brake, and will stay
on
if your parking brake doesn’t release fully. If it stays on after your parking
brake is fully released,
it means you may ‘have a brake problem. If the light
comes on while driving, pull
off the road and stop carefully. You may notice
