Manual Transmission Fluid
When to Check Manual Transmission
Fluid
It is not necessary to check the manual
transmission uid level. A transmission uid leak is
the only reason for uid loss. If a leak occurs, take
the vehicle to your GM dealer service department
and have it repaired as soon as possible.
How to Check Manual Transmission
Fluid
Because this operation can be difficult, you may
choose to have this done at your GM dealer
service department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading.
Notice:Too much or too little uid can damage
your transmission. Too much can mean that
some of the uid could come out and fall on hot
engine parts or exhaust system parts, starting a
re. Too little uid could cause the
transmission to overheat. Be sure to get an
accurate reading if you check your
transmission uid.

If the engine is warm or hot, the coolant level
should be at or above the FULL COLD/FROID line
on the side of the coolant surge tank. If the
engine is cold, the coolant level should be near
the FULL COLD/FROID line on the side of
the coolant surge tank. If it is not, you could have
a leak at the pressure cap or in the radiator
hoses, heater hoses, radiator, water pump, or
somewhere else in the cooling system.
{CAUTION:
Heater and radiator hoses, and other
engine parts, can be very hot. Do not
touch them. If you do, you can be burned.
Do not run the engine if there is a leak.
If you run the engine, it could lose all
coolant. That could cause an engine re,
and you could be burned. Get any leak
xed before you drive the vehicle.If there seems to be no leak, with the engine on,
check to see if the electric engine cooling fans
are running. If the engine hot light is on, both fans
should be running. If they are not, your vehicle
needs service.
Notice:Engine damage from running your
engine without coolant is not covered by your
warranty. SeeOverheated Engine Protection
Operating Mode on page 362for information on
driving to a safe place in an emergency.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant could require changing sooner, at
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.

Brakes
Brake Fluid
Your brake master
cylinder reservoir is
lled with DOT-3 brake
uid. SeeEngine
Compartment Overview
on page 342for the
location of the reservoir.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst
is that the brake uid goes down to an acceptable
level during normal brake lining wear. When
new linings are put in, the uid level goes back
up. The other reason is that uid is leaking out of
the brake system. If it is, you should have your
brake system xed, since a leak means that
sooner or later your brakes will not work well, or
will not work at all.So, it is not a good idea to top off your brake uid.
Adding brake uid will not correct a leak. If you add
uid when your linings are worn, then you will have
too much uid when you get new brake linings. You
should add or remove brake uid, as necessary,
only when work is done on the brake hydraulic
system.
{CAUTION:
If your vehicle has too much brake uid, it
can spill on the engine. The uid will burn if
the engine is hot enough. You or others
could be burned, and your vehicle could be
damaged. Add brake uid only when work
is done on the brake hydraulic system.
If the ignition is in ON and the brake uid is low, the
“Check Brake Fluid” message will be displayed in
the DIC. See “Check Brake Fluid Message” under
DIC Warnings and Messages on page 232.
When your brake uid falls to a low level, your
brake warning light will come on. SeeBrake
System Warning Light on page 205.

{CAUTION:
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 ashlight if you need more
light.
Be sure the battery has enough water.
You do not need to add water to the
battery installed in your new vehicle. But
if a battery has ller caps, be sure the
right amount of uid is there. If it is low,
add water to take care of that rst. If you
do not, explosive gas could be present.
Battery uid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, ush the place with water and get
medical help immediately.
{CAUTION:
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 the vehicle has one.
Negative (−) will go to a heavy, unpainted
metal engine part or to a remote negative (−)
terminal if the vehicle has one.
Do not connect positive (+) to negative (−)or
you will get a short that would damage
the battery and maybe other parts too. And do
not connect the negative (−) cable to the
negative (−) terminal on the dead battery
because this can cause sparks.
