Warning Lights and Indicators
This section describes the warning lights and gages that may b\
e on your
vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something
is wrong before it
becomes serious enough to cause an expensive repair or replacem\
ent.
Paying attention to your warning lights and gages could also s\
ave you or
others from injury.
Warning lights go on when there may be
or is a problem with one of your
vehicle’s functions.
As you will see in the details on the next few pages,
some warning lights come on briefly when you turn the ignition\
key just to
let you know they’re working.
If you are familiar with this section, you
should not be alarmed when this happens.

Gages can indicate when there may be or is a problem with one of your
vehicle’s functions. Often gages and warning lights work together to let
you
know when there’s a problem with your vehicle.
When one of the warning lights comes on and stays on when you are
driving,
or when one of the gages shows there may be a problem, check the
section that tells you what to do about
it. Please follow the manual’s advice.
Waiting
to do repairs can be costly - and even dangerous. So please get to
know your warning lights and gages. They’re
a big help.
Brake System Warning Light
The red brake system
warning light is
located at the bottom
right corner
of the
instrument cluster
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 parts working well.
Your vehicle also has rear-wheel anti-lock brakes.
If the warning light
comes on, there could be
a brake problem with either your regular or
rear-wheel anti-lock 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.
If the light comes on while you are driving, pull off the road and stop
carefully.
You may notice that the pedal is harder to push. Or, the pedal may
go closer
to the floor. It may take longer to stop. If the light is still on, have
the vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)

Some Other Rainy Weather Tips
0 Turn on your low-beam headlights - not just your parking llgnts - to
help make you more visible to others.
Besides slowing down, allow some extra following distance. And be
especially careful when you pass another vehicle. Allow yourself more
clear room ahead, and be prepared to have your view restricted by road
spray.
Have good tires with proper tread depth. (See “Tires” in the Index.)
City Driving
One of the biggest problems with city streets is the amount of traffic on
them. You’ll want to watch out for what the other drivers are doing and pay
attention to traffic signals.
Here are ways to increase your safety
in city driving:
Know the best way to get to where you are going. Get a city map and
plan your trip
into an unknown part of the city just as you would for a
cross-country trip.
save time and energy. (See the
next section, “Freeway Driving.”)
0 Try to use the freeways that rim and crisscross most large cities. You’ll
0 Treat a green light as a warning signal. A traffic light is there because
the corner is busy enough to need
it. When a light turns green, and just
before you start to move, check both ways for vehicles that have not
cleared the intersection or may be running the red light.

Hazard Warning Flashers
Your hazard warning
flashers let
you warn
others. They also let
police know you have
a problem. Your front
and rear turn signal
lights will
flash on
and off.
But they won’t flash if
you’re braking.
Press the button
in to
make your front and
rear turn signals flash
on and
off. Your
hazard warning
flashers work no
matter what position
your key
is in, and
even if
the key isn’t
in.
To turn off the
flashers,
pull out on
the collar.
When the hazard warning flashers are on, your turn signals won’t work.

What to use
Refer to the Maintenance Schedule to determine what kind of lubricant to
use. See “Recommended Fluids and Lubricants”
in the Index.
Engine Coolant
The following explains your cooling system and how to add coolant when it
is low. If you have a problem with engine overheating, see “Engine
Overheating”
in the Index.
The proper coolant for your vehicle
will:
Give freezing protection down to -20 OF (-29”C), or -34°F (-37°C) in
Canada and for vehicles with the cold climate option.
Give boiling protection up to 258 OF ( 125 O C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
What to Use
Use a mixture of one-half clean wuter (preferably distilled) and one-half
antifreeze that meets
“GM Specification 6038-M,” which won’t damage
aluminum parts.
You can also use a recycled coolant conforming to “GM
Specification 6038-M” with a complete coolant flush and refill. If you use
this mixture, you don’t need to add anything else.
