Try to have a GM dealer or a professional towing
service tow your vehicle. They can provide the right
equipment and know how to tow
it without damage. See
“Roadside Assistance”
in the Index.
If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like fog
lamps, aero skirting, or special tires and wheels, these
things can be damaged during towing.
Before
you do anything, turn on the hazard
warning flashers.
When
you call, tell the towing service:
Whether your vehicle has rear-wheel drive or the
all-wheel-drive option.
That your vehicle cannot be towed from the front or

Downloaded from www.Manualslib.com manuals search engine A vehicle can fall from a car carrier if it isn’t
adequately secured. This can cause a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains
or
steel cables before it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle.
When your vehicle is being towed, have the ignition key
in the
OFF position. The steering wheel should be
clamped in a straight-ahead position, with a clamping
device designed for towing service.
Do not use the
vehicle’s steering column lock for this. The transmission
should be in
NEUTRAL (N) and the parking
brake released.
If your vehicle has the all-wheel-drive option, it can
only be towed with all four wheels off the ground.
A
dolly must be used under the un-raised wheels when
towing
or the vehicle must be transported on a flat
bed carrier.
Don’t have your vehicle towed with the wheels in
contact with the ground if it has all-wheel drive. If a
vehicle with all-wheel drive must be towed with
sling-type or wheel-lift equipment, then either
the front
or rear wheels must be supported
on a dolly.
I NOTICE:
If your vehicle has all-wheel drive, do not have it
towed with the wheels in contact with the ground
or vehicle damage may occur. A dolly must be
used under the un-raised wheels when towing or
the vehicle must be transported on a flat
bed carrier.

The jacking equipment you’ll need is stored by your
vehicle’s rear doors, along the passenger side wall.
Remove your jack cover by pulling it away from the
side wall and down
to release the tabs securing the top
of the cover. Remove the wheel blocks
by turning the top nut
counterclockwise. Remove the nut and washer, then pull
the wheel blocks off the bolt. Push down on the bolt and
remove
the hooked end from the slot. Slide the jack
toward the front
of the vehicle and lift it from the
mounting. Remove the extension and
the ratchet from
the pouch.

the hole in the rear door frame, above the bumper.
Turn the ratchet clockwise until the tire is against the
underside
of the vehicle.
You will feel two “clicks” when the tire is up all the
way. Try
to move the tire with your hands to make
sure it is securely in place.
The compact spare is for temporary use
only. Replace
the compact spare tire with a full-size tire as soon as you
can. See “Compact Spare Tire”
in the Index. See the
storage instructions label to restore your compact
spare properly.
Return the jacking equipment
to its proper location.

To remove the air filter, lift the hood, unsnap both clips
and remove the top. After changing the filter, snap both
clips to secure the air cleaner. Be sure
the air cleaner lid
is correctly positioned
to seal out dust and contaminants
that are harmful to your engine.
Make sure
the fresh air hose is still attached after the
filter change.
Refer to
the Maintenance Schedule to determine when to
replace the air filter and the crankcase ventilation filter.
See “Scheduled Maintenance” in the Index.
Operating the engine with the air cleaner off
can cause
you or others to be burned. The air
cleaner not only cleans the air, it stops flame if
the engine backfires. If it isn’t there, and the
engine backfires, you could be burned. Don’t
drive with it
off, and be careful working on the
engine with the air cleaner off.
I NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.

Remember, cleaning products can be hazardous. Some
are toxic. Others can burst
into flame if you strike a
match or get them on
a hot part of the vehicle. Some are
dangerous
if you breathe their fumes in a closed space.
When you use anything from
a container to clean your
vehicle, be sure to follow the manufacturer’s warnings
and instructions. And always open your doors
or
windows when you’re cleaning the inside.
Never use these to clean your vehicle:
NOTICE:
If your vehicle has P235/65R15 size tires, don’t
use tire chains. They can damage your vehicle
because there’s not enough clearance.
If you have other size tires, 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 rear axle
tires and tighten them as tightly
as possible with
the ends securely fastened. Drive
slowly and
follow the chain manufacturer’s instructions. If
you can hear the chains contacting 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.
