in many other ways if the wrong
replacement brake parts are
installed or if parts are improperly
installed.
Brake Fluid
The brake master cylinder reservoir
is filled with DOT 3 brake fluid. See
Engine Compartment Overview
0181 for the location of the
reservoir.
There are only two reasons why the
brake fluid level in the reservoir
might go down:
. The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up. .
A fluid leak in the brake
hydraulic system can also cause
a low fluid level. Have the brake
hydraulic system fixed, since a
leak means that sooner or later
the brakes will not work well.
Do not top off the brake fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake hydraulic
system. See “Checking Brake
Fluid” in this section. Refer to the Maintenance Schedule
to determine when to check the
brake fluid. See
Maintenance
Schedule 0246.
Checking Brake Fluid
Check brake fluid by looking at the
brake fluid reservoir. See Engine
Compartment Overview 0181.
The fluid level should be above
MIN. If it is not, have the brake
hydraulic system checked to see if
there is a leak.

194 Vehicle Care
After work is done on the brake
hydraulic system, make sure the
level is above the MIN but not over
the MAX mark.
If the brake fluid is below the MIN
line, the brake warning light will
illuminate. Add brake fluid up to the
MAX line.
What to Add
Use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants0257.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering the
reservoir.
{Warning
With the wrong kind of fluid in the
brake hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake fluid.
Caution
. Using the wrong fluid can
badly damage brake
hydraulic system parts. For
example, just a few drops of
mineral-based oil, such as
engine oil, in the brake
hydraulic system can
damage brake hydraulic
system parts so badly that
they will have to be
replaced. Do not let
someone put in the wrong
kind of fluid.
. If brake fluid is spilled on
the vehicle's painted
surfaces, the paint finish
can be damaged. Be careful
not to spill brake fluid on the
vehicle. If you do, wash it off
immediately.
Battery - North America
The original equipment battery is
maintenance free. Do not remove
the cap and do not add fluid. Refer to the replacement number
shown on the original battery label
when a new battery is needed. See
Engine Compartment Overview

Fuses and Circuit
Breakers
{Danger
Fuses and circuit breakers are
marked with their ampere rating.
Do not exceed the
specified amperage rating when
replacing fuses and circuit
breakers. Use of an oversized
fuse or circuit breaker can result
in a vehicle fire. You and others
could be seriously injured or
killed.
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit
breakers. This greatly reduces the
chance of fires caused by electrical
problems.
Look at the silver-colored band
inside the fuse. If the band is broken
or melted, replace the fuse. Be sure
you replace a bad fuse with a new
one of the identical size and rating. Spare fuses are provided and can
be found in the passenger
compartment fuse box.
Engine Compartment
Fuse Block
The fuse block is in the engine
compartment of the vehicle.
Remove the cover by pushing the
tab and lifting the cover up.
Fusible Links
If the electrical equipment does not
operate and fuses are in good
condition, check the fusible links.
If any of these fusible links are
melted, replace with only Genuine
GM parts.
Caution
Spilling liquid on any electrical
component on the vehicle may
damage it. Always keep the
covers on any electrical
component.

Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
3. Turn off the ignition on both vehicles. Unplug unnecessary
accessories from the cigarette
lighter or the accessory power
outlet. Turn off the radio and all
lamps that are not needed.
This will avoid sparks and help
save both batteries. And it
could save the radio!
4. Open the hoods and locate the positive (+) and negative (−)
terminal locations of the other
vehicle.
{Warning
Using a match near a battery can
cause battery gas to explode.
People have been hurt doing this,
and some have been blinded.
Use a flashlight if you need more
light.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.
{Warning
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running. 5. Check that the jumper cables
do not have loose or missing
insulation. If they do, you could
get a shock. The vehicles
could be damaged too.
Before you connect the cables,
here are some basic things you
should know. Positive (+) will
go to positive (+) or to a remote
positive (+) terminal if
equipped. Negative (−) will go
to an unpainted metal part or to
a remote negative (−) terminal
if equipped.
Do not connect positive (+) to
negative (−) or you will get a
short that would damage the
battery and possibly other parts
too. Do not connect the
negative (−) cable to the
negative (−) terminal on the
dead battery because this can
cause sparks.
6. Connect the red positive (+) cable to the positive (+)
terminal (1) of the dead battery.
Use a remote positive (+)
terminal if equipped. Do not let
the other end touch metal.

Connect it to the positive (+)
terminal (4) of the good battery.
Use a remote positive (+)
terminal if equipped.
7. Connect the black negative (−) cable to the negative (−)
terminal (3) of the good battery.
Use a remote negative (−)
terminal if equipped.
Do not let the other end touch
anything until the next step.
The other end of the
negative (−) cable does not go
to the dead battery. It goes to
the shock tower, or to a remote
negative (−) terminal on the
vehicle with the dead battery.
8. Connect the other end of the negative (−) cable to the
negative (−) grounding point (2)
on the shock tower of the
vehicle with the dead battery.Caution
Make sure the jumper cables do
not touch moving parts in the
engine compartment and that the
cable clamps do not contact any
other metal.
9. Start the vehicle with the good battery and run the engine for a
few minutes.
10. Keep the engine speed of the booster vehicle at about 2,000
rpm, and start the engine of the
vehicle being jump started.
Caution
Do not keep the starter motor
engaged for more than
10 seconds. If the engine does
not start right away, turn the key
off and wait three to four seconds
before trying again. 11. After starting the engine,
disconnect jumper cables as
directed below.
12. If it will not start after a few tries, it probably needs service.
Caution
If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct order,
making sure that the cables do
not touch each other or other
metal.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle
and removing the jumper cables,
allow it to idle for several minutes.
