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.
Making Turns
NOTICE:
Making very sharp turns while trailering could cause the traile\
r
to come in contact with the vehicle. Your vehicle could be
damaged. Avoid making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than normal. Do this
so your trailer won’t strike soft shoulders, curbs, road signs, trees, or other
objects. Avoid jerky or sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra wiring and a
heavy-duty
turn signal flasher (included in the optional trailering package).
The green arrows on your instrument panel will flash whenever you signal a
turn or lane change. Properly hooked up, the trailer lamps will also flash,
telling other drivers you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your instrument panel will flash
for turns even if the bulbs on the trailer are burned out. Thus, you may think
drivers behind you are seeing your signal when they are not. It’s important
to check occasionally to be sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start down a long or steep
downgrade. If you don’t shift down, you might have to use your brakes
so
much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your speed to around 45 mph
(70 Wh) to reduce the possibility of engine and transmission overheating.

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.
If your vehicle has been changed since it was factory-new by adding things
like fog lamps, aero skirting, or special tires and wheels, these things could
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, four-wheel drive or
all-wheel drive.
The make, model, and year of your vehicle.
Whether you can move the shift lever for the transmission and shift the
transfer case,
if you have one.
If there was an accident, what was damaged.

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, then ge\
ntly 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 warning flashers.

The following steps will tell you how to use the jack and change a tire.
Your vehicle is equipped with work gloves and a plastic ground mat to assist
in the changing of a flat tire.
Jacking Equipment Storage
The jacking equipment you’ll need is stored along the driver’s rear wall. In
some cases,
you may have to remove the spare tire in order to reach the
jack.
To remove your jack
cover, pull
up on the
latch. Pull the wheel
blocks, jack and wheel
wrench
off.

If your vehicle has four-wheel drive, you will have a remote oil filter. There
is a special access door in the steering linkage shield assembly located under
the radiator support. Twist the screw to lock or unlock the door.
Engine Coolant Heater
An engine coolant heater can be a big help if you have to park outside in
very cold weather,
0°F (-18 “C) or colder. If your vehicle has this option,
see “Engine Coolant Heater” in
the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer? Don’t let used oil stay
on your skin for very long. Clean your skin and nails with soap and water,
or a good hand cleaner. Wash or properly throw away clothing or rags
containing used engine oil. (See the manufacturer’s warnings about the use
and disposal of oil products.)
Used oil can be a real threat to the environment. If you change your own oil,
be sure to drain all free-flowing oil from the filter before disposal. Don’t
ever dispose of oil by putting it in the trash, pouring
it on the ground, into
sewers, or into streams or bodies of water. Instead, recycle it by taking
it to
a place that collects used oil. If you have a problem properly disposing of
your used oil, ask your dealer, a service station or a local recycling center
for help.
Air Cleaner
To remove the rectangular air cleaner filter for the 4.3L (VIN W) engine,
open both clamps and push the rear
of the air cleaner back toward the rear
of the engine compartment to change the filter.
