burn you and gas that can
explode. You can be badly
hurt if you are not careful.
See Jump Starting - North
America0447 for tips on
working around a battery
without getting hurt.
Infrequent Usage: Remove the
black, negative (−) cable from

battery from running down.
Extended Storage: Remove
the black, negative (−) cable
from the battery or use a
battery trickle charger.
All-Wheel Drive
If the vehicle is equipped with
All-Wheel-Drive (AWD), this is
an additional system that
needs lubrication.

Under normal driving
conditions, transfer case fluid
does not require maintenance
unless there is a fluid leak or
unusual noise. If required, have
the transfer case serviced by
your dealer.
Park Brake and
P (Park) Mechanism
Check
{Warning
When you are doing this
check, the vehicle could
begin to move. You or
others could be injured and
property could be damaged.
Make sure there is room in
front of the vehicle in case it
begins to roll. Be ready to
apply the regular brake at
once should the vehicle
begin to move. Park on a fairly steep hill, with
the vehicle facing downhill.
Keeping your foot on the
regular brake, set the parking
brake.
.To check the parking brake's
holding ability: With the
engine running and the
transmission in N (Neutral),
slowly remove foot pressure
from the regular brake pedal.
Do this until the vehicle is
held by the parking
brake only.
.Automatic transmission
vehicles only: To check the
P (Park) mechanism's holding
ability: With the engine
running, shift to P (Park).
Then release the parking
brake followed by the
regular brake.
Contact your dealer if service
is required.

For more information about
the vehicle battery, see
Battery - North America0399.
If the battery has run down,
try to use another vehicle and
some jumper cables to start
your vehicle. Be sure to use
the following steps to do it
safely.
{Warning
WARNING: Battery posts,
terminals and related
accessories can expose you
to chemicals including lead
and lead compounds, which
are known to the State of
California to cause cancer
and birth defects or other
reproductive harm. Wash
hands after handling. For
more information go to
www.P65Warnings.ca.gov. See California Proposition
65 Warning
01.
{Warning
Batteries can hurt you. They
can be dangerous because:
.They contain acid that can
burn you.
.They contain gas that can
explode or ignite.
.They contain enough
electricity to burn you.
If you do not follow these
steps exactly, some or all of
these things can hurt you.
Caution
Ignoring these steps could
result in costly damage to
the vehicle that would not
be covered by the vehicle
warranty. Trying to start the
vehicle by pushing or pulling
it will not work, and it could
damage the vehicle.
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.

4. Turn the ignition off. Turnoff all lights and
accessories in both
vehicles, except the hazard
warning flashers if needed.
{Warning
An electric fan can start up
even when the engine is not
running and can injure you.
Keep hands, clothing, and
tools away from any
underhood electric fan.
{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
(Continued)

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. Connect one end of the red positive (+) cable to the
remote positive (+)
terminal on the discharged
battery.
6. Connect the other end of the red positive (+) cable to
the positive (+) terminal of
the good battery.
7. Connect one end of the black negative (–) cable to
the negative (–) terminal of
the good battery. 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 a heavy,
unpainted metal
engine part.
8. Connect the other end of the black negative (–) cable
to the negative (–)
grounding point for the
discharged battery.
9. Start the engine in the vehicle with the good
battery and run the engine
at idle speed for at least
four minutes.

After starting the disabled
vehicle and removing the
jumper cables, allow it to idle
for several minutes.
Towing the
Vehicle
Transporting a
Disabled Vehicle
(Electronic Shifter)
Caution
Incorrectly transporting a
disabled vehicle may cause
damage to the vehicle. Use
proper tire straps to secure
the vehicle to the flatbed
tow truck. Do not strap or
hook to any frame,
underbody, or suspension
component not specified
below. Do not move vehicles
with drive axle tires on the
ground. Damage is not
covered by the vehicle
warranty.
Caution
The vehicle may be equipped
with an electric parking
brake and/or an electronic
shifter. In the event of a loss
of 12-volt battery power, the
electric parking brake
cannot be released, and the
vehicle cannot be shifted to
N (Neutral). Tire skates or
dollies must be used under
the non-rolling tires to
prevent damage while
loading/unloading the
vehicle. Dragging the vehicle
will cause damage not
covered by the vehicle
warranty.
Caution
The vehicle may be equipped
with a tow eye. Improper use
of the tow eye may cause
damage to the vehicle and is
not covered by the vehicle
warranty. If equipped, use(Continued)
Caution (Continued)
the tow eye to load the
vehicle onto a flatbed tow
truck from a flat road
surface, or to move the
vehicle a very short distance
at a walking pace. The tow
eye is not designed for
off-road recovery. The
vehicle must be in
N (Neutral) with the electric
parking brake released when
using the tow eye.
Contact a professional towing
service if the disabled vehicle
must be transported. GM
recommends a flatbed tow
truck to transport a disabled
vehicle. Use ramps to help
reduce approach angles,
if necessary.
If equipped, a tow eye may be
located near the spare tire or
emergency jack. Do not use
the tow eye to pull the vehicle
from the snow, mud, sand,
or ditch. Tow eye threads may
