10-20 Vehicle Care .
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 on page 11-3 .
Checking Brake Fluid Check brake fluid by looking at the
brake fluid reservoir. See Engine
Compartment Overview on
page 10-7 .
The fluid level should be above
MIN. If it is not, have the brake
hydraulic system checked to see if
there is a leak. 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
Lubricants on page 11-11 .
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.

Vehicle Care 10-21
{ 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 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 on
page 10-7 for battery location.
{ WarningWARNING: Battery posts,
terminals, and related
accessories contain lead and lead
compounds, chemicals known to
the State of California to cause
cancer and birth defects or other
reproductive harm. Wash hands
after handling. See California
Proposition 65 Warning on
page 10-2 .
Vehicle Storage
{ Warning
Batteries have acid that can burn
you and gas that can explode.
You can be badly hurt if you are
(Continued) Warning (Continued) not careful. See Jump Starting on
page 10-55 for tips on working
around a battery without
getting hurt.
Extended Storage Switch
If any electrical equipment does not
operate, remove the extended
storage switch and check for an
open fuse.

Vehicle Care 10-25
Fuses and Circuit
Breakers 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
GMus parts.
{ Caution
Spilling liquid on any electrical
component on the vehicle may
damage it. Always keep the
covers on any electrical
component.

10-58 Vehicle Care 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. { CautionMake 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.
