Winter Driving Include an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth and
reflective warning triangles. And,
if you will be driving
under severe conditions, include a small bag of
sand, a
piece of old carpet or a couple
of burlap bags to help
provide traction. Be sure you properly secure these
items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
However, if there is snow or ice between your tires and
the road, you can have a very slippery situation. You’ll
have
a lot less traction or “grip” and will need to be
very careful.
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You may want to put winter emergency supplies in
your vehicle.

Don’t leave an unsecured child restraint in
your vehicle.
0 When you carry something inside the

it whenever you can.
0 Don’t leave a seat folded down unless you
need to.
Payload (Cargo Van Only)
The payload capacity is shown on the Certificatioflire
label. This is the maximum load capacity that your
vehicle can carry. Be sure to include the weight of the people inside as part
of your load.
If you added any
accessories or equipment after your vehicle left the
factory, remember to subtract the weight
of these things
from the payload. You should never exceed the
GVWR
or the GAWR. Your dealer can help you determine
your payload.
Electronic Level Control (Option)
On vehicles equipped with the optional electronic level
control, the rear of the vehicle is automatically kept
level as you load or unload your vehicle. However, you
should still not exceed the
GVWR or the GAM.
You may hear the compressor operating when you load
or unload your vehicle, and periodically as the system
self-adjusts.
This is normal.
The compressor should operate for brief periods of time.
If the sound continues for an extended period of time,
your vehicle needs service. To keep your battery from
being drained, you may want to remove the ELC fuse in
the fuse control panel until you can get your vehicle
serviced (see “Fuses and Circuit Breakers” in the Index)\
.
Using heavier suspension components to get added
durability might not change your weight ratings. Ask
your dealer to help you load your vehicle the right way.

Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving
is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load
is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without
a trailer. This
can help you avoid situations that require heavy braking
and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing
a trailer. And, because you’re a good deal
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left.
To move the trailer to the right, move your
hand to the right. Always back up slowly and, if
possible, have someone guide you,

Towing Your Vehicle
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:
0 That your vehicle has front-wheel drive.
That your vehicle cannot be towed from the front or
0 The make, model and year of your vehicle.

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. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks. They will damage drivetrain and
suspension components.
~~
NOTICE:
If you are using car-carrier equipment, you must
pull the Electronic Level Control (ELC) fuse, in
the instrument panel fuse block, before securing
the vehicle.
Damage to the shocks or leveling system may
occur if the Electronic Level Control (ELC) fuse
is not disabled.
When your vehicle is being towed, have the ignition key
in
OFF. 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. For front towing, the
transaxle should be in
PARK (P) and the parking brake
released. For rear towing, the transaxle should be in
NEUTRAL (N) and the parking brake engaged.

NOTICE:
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.
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.
I 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.
Storing a Flat or 5are Tire and Tools
A CAUTION:
Storing a jack, a tire or other equipment in the
passenger compartment
of the vehicle could
cause injury.
In a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
Lay
the tire near the rear of the vehicle with the valve
stem down. Slide the cable retainer through the center
of
the wheel and start to raise the tire. When the tire is
almost in the stored position, turn the tire so the valve is
towards the rear
of the vehicle. This will help when you
check and maintain tire pressure in the spare.
Keep raising the wheel until you hear the hoist
mechanism click twice. This means the wheel
is firmly
stored against the underside
of the vehicle. Push
against the wheel to be sure
it does not move and is
stored securely.

NOTE:
INSTALL
OF BAG , BOlTOM
.BAG & TOOLS
I TOOL STORAGE
Replace all jacking tools as they were stored in the jack
storage compartment and replace the compartment
cover. To replace the cover, line up the tabs on the right
of the cover with the slots
in the cover opening. Push the
cover in place and push down the tab
so that it rests in
the groove. This secures the cover in place. Unless you have the plastic “bolt-on” wheel covers, be
sure
to also store the center cap. When you replace the
compact spare with
a full-size tire, replace the bolt-on
wheel covers and the center cap. Tighten them “hand
tight” over the wheel nuts, using the folding wrench.
Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi
(420 Pa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure your
spare tire
is correctly inflated. The compact spare is
made
to perform well at speeds up to 65 mph (105
km/h) for distances up to 3,000 miles (5 000 km), so you
can finish your trip and have your full-size tire repaired
or replaced where
you want. Of course, it’s best to
replace your spare with a full-size tire as soon as you
can. Your spare will last longer and be in good shape in
case you need it again.

Checking or Replacing the Air Cleaner
1. Unlatch the two hooks on top of the air
cleaner housing.
2. Turn back the air inlet panel and rest it on top of the
housing. The air intake tube is designed to flex back;
you do not need to disconnect it.
3. After replacing the air cleaner filter, seat the tabs on
the bottom of the panel into the slots at the bottom.
4. Latch the hooks to secure the panel in place. If the
panel moves easily, check that the tabs
are seated
correctly in
the slots.
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.
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.
Passenger Compartment Air
Filter Replacement
Passenger compartment air, both outside and
recirculated air, is routed through
a passenger
compartment filter, which is part of
a two-piece filter
system. The filter removes certain contaminants from
the air, including pollen and dust particles. Reductions
in airflow, which may occur more quickly in dusty
areas, indicate that the filter needs
to be replaced early.
For how often to change the air filter, see “Maintenance
Schedule” in the Index.
The access panel for the air filter is in the back
of the
glove box.
