9-20 Driving and Operating
This is the only position from which
the key can be removed. If the key
cannot be removed, make sure the
shift lever is in P (Park).
The ignition switch can bind in the
LOCK/OFF position with the wheels
turned off center. If this happens,
move the steering wheel from right
to left while turning the key to ACC/
ACCESSORY. If this does not work,
then the vehicle needs service.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steadypressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting to N (Neutral), firmly apply the
brakes and steer the vehicle to a
safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition
to LOCK/OFF. On vehicles with
an automatic transmission, the
shift lever must be in P (Park) to
turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake on page 9-31.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
turn the ignition to ACC/
ACCESSORY. 2 (ACC/ACCESSORY):
This
position provides power to some of
the electrical accessories. It unlocks
the steering wheel and ignition. To
move the key from ACC/
ACCESSORY to LOCK/OFF, push
in the key and then turn it to
LOCK/OFF.
3 (ON/RUN): The ignition switch
stays in this position when the
engine is running. This position can
be used to operate the electrical
accessories, including the
ventilation fan and 12-volt power
outlets, as well as to display some
warning and indicator lights. This
position can also be used for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes. The transmission is also
unlocked in this position on
automatic transmission vehicles.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or ON/RUN position with the engine

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.
{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 on
the original battery label when a
new battery is needed.
{Warning
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.
Vehicle Storage
{Warning
Batteries have acid that can burn
you and gas that can explode.
You can be badly hurt if you are
not careful. See
Jump Starting on
page 10-66 for tips on working
around a battery without
getting hurt.

10-68 Vehicle Care
1. Remote Positive (+) Terminal
2. Remote Negative (−)Terminal
1. The vehicle used to jump startmust have a 12-volt battery with
a negative ground.
{Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. The vehicles should be close enough for the jumper cables to
reach, but the vehicles should
not be touching. Touching could
cause grounding and possible
electrical system damage.
Put both vehicles in P (Park) and
set the parking brake firmly. 3. Unplug accessories plugged into
the cigarette lighter or the
accessory power outlet. Turn off
the radio and all lamps that are
not needed. Turn off the ignition
on both vehicles.
4. Locate the positive (+) and negative (−) terminals on both
vehicles. Some vehicles have
remote jump starting terminals.
{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. 5. The remote positive (+)
terminal (1) is located on the
underhood fuse block, on the
driver side. Lift the red cap to
uncover the terminal.
The remote negative (−)
terminal (2) is a stud behind the
metal tab stamped with GND (−)
near the driver side strut tower.
6. The jumper cables should be in good working condition with no
loose or missing insulation. The
vehicles could be damaged if
they are not.
7. Connect the red positive (+) cable to the positive (+) terminal
on the vehicle with the dead
battery. Use a remote
positive (+) terminal if the
vehicle has one.
8. Do not let the other end touch metal. Connect it to the
positive (+) terminal of the good
battery. Use a remote
positive (+) terminal if the
vehicle has one.

access to tools and equipment
to inspect the belts and
recommend adjustment or
replacement when necessary.
Brakes
Brakes stop the vehicle and are
crucial to safe driving.
.Signs of brake wear may include
chirping, grinding, or squealing
noises, or difficulty stopping.
.Trained dealer technicians have
access to tools and equipment
to inspect the brakes and
recommend quality parts
engineered for the vehicle.
Fluids
Proper fluid levels and approved
fluids protect the vehicle’s systems
and components. See
Recommended Fluids and
Lubricants on page 11-11 for GM
approved fluids.
.Engine oil and windshield
washer fluid levels should be
checked at every fuel fill.
.Instrument cluster lights may
come on to indicate that fluids
may be low and need to be
filled.
Hoses
Hoses transport fluids and should
be regularly inspected to ensure
that there are no cracks or leaks.
With a multi-point inspection, your
dealer can inspect the hoses and
advise if replacement is needed. Lamps
Properly working headlamps,
taillamps, and brake lamps are
important to see and be seen on
the road.
.Signs that the headlamps need
attention include dimming, failure
to light, cracking, or damage.
The brake lamps need to be
checked periodically to ensure
that they light when braking.
.With a multi-point inspection,
your dealer can check the lamps
and note any concerns.
Shocks and Struts
Shocks and struts help aid in control
for a smoother ride.
.Signs of wear may include
steering wheel vibration, bounce/
sway while braking, longer
stopping distance, or uneven
tire wear.
.As part of the multi-point
inspection, trained dealer
technicians can visually inspect
