Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to follow the steps below to
do it safely.
On vehicles equipped with the optional power sliding
door, a low-voltage battery or replacing a battery may
cause the system
to become inoperative. See Power
Sliding Door (PSD) on paae 2-76for more information.

burn you.
If you don’t follow these steps exactly, some
or all
of these things can hurt you.
Notice: Ignoring these steps could result in costly
damage to your vehicle that wouldn’t be covered
by your warranty.
Trying to start your vehicle by pushing or pulling
it
won’t work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice: If the other system isn’t a 12-volt system
with a negative ground, both vehicles can be
damaged.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other. If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put an automatic
transaxle in PARK (P) or a manual transaxle in
NEUTRAL before setting the parking brake.

If you need to replace any of your wheels, wheel bolts or
wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous.
It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts and wheel nuts for replacement.
I
Notice: The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height,
vehicle ground clearance and tire or tire chain
clearance to the body and chassis.
See
Changing a Flat Tire on page 5-70 for more
information.
Used Replacement WI els
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used
or how far it’s been driven. It could fail suddenly
and cause a crash. If you have to replace a
wheel, use a new
GM original equipment wheel.
Tire Chains
Notice: Use tire chains only where legal and only
when you must. Use only SAE Class
“S” type chains
that are the proper size for your tires. Install them
on the front tires and tighten them as tightly
as possible with the ends securely fastened.
Drive slowly and follow the chain manufacturer’s
your vehicle, stop and retighten them. If the contact continues, slow down until
it stops. Driving too
fast or spinning the wheels with chains on will
damage your vehicle.

Your air inflator will automatically shut off after about
10 minutes. The light in the switch will blink. After about
one minute you can use the system again. Press the
inflator switch and the indicator light will come on.
Notice: Don’t run your air inflator for longer than
30 minutes at one time. If you do, you may damage
the system.
After running the air inflator for
30 minutes, wait at least
10 minutes before restarting the air inflator.
To turn off the inflator, do the following:
1. Press the switch and detach the hose, first from the

the glove box.
To put the cover back on, line up the tabs at the back
of the cover and put it in place. Push down the tab
to secure the cover.
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially
if you maintain your tires properly. If air
goes out of a tire, it’s much more likely to leak out
slowly. But if you should ever have a “blowout”, here are
a few tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot
off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake
to a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like
a skid and may require the same correction you’d use
in a skid. In any rear blowout, remove your foot from
the accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may
be very bumpy and noisy, but you can still steer.
Gently brake to a stop
- well off the road if possible.
If a tire goes flat, the next part shows how to use
your jacking equipment to change a flat tire safely.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving
slowly to a level place. Turn on your
hazard v.--nin- 'lashers.
Chan,,,lg a tire can cause an injury. The
vehicle can
slip off the jack and roll over you
or other people.
You and they could be badly
injured. Find a level place to change your tire.
To help prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won't
move, you can put blocks at the front and
rear of the tire farthest away from the one
being changed. That would be the tire on
the other side
of the vehicle, at the
opposite end. The following
steps will tell you how to use the jack and
change a tire.

9. Tighten the wheel nuts
firmly in a crisscross
sequence, as shown.
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel
to come loose
and even come
off. This could lead to an
accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new
GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque specification. See ”Capacities
and Specifications”
in the Index for wheel nut
torque specification.
Nofice: Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel
nuts
in the proper sequence and to the proper torque
specification. See “Capacities and Specifications”
in the index for the wheel nut torque specification.
10. Don’t try to put a wheel cover on the compact spare
tire. It won’t fit. Store the wheel cover securely in
the rear of the vehicle until you have the flat tire
repaired or replaced.
Notice: Wheel covers won’t fit on your compact
spare.
If you try to put a wheel cover on your
compact spare, you could damage the cover or
the spare.

Part 5: Owner Checks and Services on page 6-10
and Part C: Periodic Maintenance Inspections on
page
6- 14.
Footnotes
t The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle
's useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
mainienance
be recoraea.
+ A good time to check your brakes is during tire
rotation. See Brake System Inspection
on page 6-15.
Engine Oil and Chassis Lubrication
Scheduled Maintenance
Change engine oil and filter as indicated by the GM
Oil Life System (or every 12 months, whichever
occurs first). Reset the system.
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage at
which an oil change will be indicated can vary
considerably. For the oil life system to work properly,
you must reset the system every time the
oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary.
A change engine oil message will come on.
Change your oil as soon
as possible within the next
two times you stop for fuel. It
is possible that, if you are
driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over
a year. However, your engine oil and filter must be
changed at least once a year and at this time the system
must be reset. It is also important to check your oil
regularly and keep it at the proper level.

If it does, you or others
could be injured. Follow the steps below.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. See
Parking Brake on page 2-39 if necessary.
Do not use the accelerator pedal, and be ready to
turn
off the engine immediately if it starts.
3. Try to start the engine in each gear. The starter
should work only in PARK (P) or NEUTRAL (N).
If the starter works in any other position, your
vehicle needs service. When
you are doing this check, the vehicle
could move suddenly.
If it does, you or others
could be injured. Follow the steps below.
