You should always attach chains between your vehicle and your trailer.
Cross the safety chains under the tongue of the trailer
so that the tongue will
not drop to the road if it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch manufacturer or by the
trailer manufacturer. Follow the manufacturer’s recommendation for
attaching safety chains and do not attach them to the bumper. Always leave
just enough slack
so you can turn with your rig. And, never allow safety
chains to drag on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 pounds (450 kg) loaded, then it needs
its own brakes
- and they must be adequate. Be sure to read and follow the
instructions for the trailer brakes
so you’ll be able to install, adjust and
maintain them properly.
Your trailer brakes system can tap into vehicle’s hydraulic brake system
except:
Don’t tap into your vehicle’s brake system if the trailer’s brake system will
use more than 0.02 cubic inch (0.3~~) of fluid from your vehicle’s master
cylinder. If it does, both braking systems won’t work well. You could even
lose your brakes.
Will the trailer parts take 3,000 psi (20 650 kPa)
of pressure? If not, the
trailer brake system must not be used with your vehicle.
If everything checks out this far, then make the brake fluid tap at
the port on
the master cylinder that sends fluid to the rear brakes. But don’t use copper
tubing for this. If you do, it will bend and finally break off. Use steel brake
tubing.
Driving with a Trailer
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, lights, 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 lights and any trailer brakes are still working.

If it still won’t start, it

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.
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:
0 Whether your vehicle has rear-wheel drive or four-wheel drive.
The make, model, and year of your vehicle.
0 Whether you can move the shift lever for the transmission and shift the
transfer case, if you have one.
0 If there was an accident, what was damaged.

This vehicle has a clutched engine cooling fan. When the clutch is engaged,
the fan spins faster to provide more air to cool the engine. In most every day
driving conditions the clutch is not engaged. This improves fuel economy
and reduces fan noise. Under heavy vehicle loading, trailer towing and/or
high outside temperatures, the fan speed increases when
the clutch engages.
So you may hear an increase in fan noise. This is normal and should not be
mistaken as the transmission slipping or making extra shifts. It is merely the
cooling system functioning properly. The fan will slow down when
additional cooling is not required and the clutch disengages.
You may also hear this fan noise when you start the engine. It will go away
as the fan clutch disengages.
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, 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.

Spinning your wheels can destroy parts of your vehicle as well\
as
the tires. If you spin the wheels too fast while shifting you\
r
transmission back and forth, you can destroy your transmission. \
For information about using tire chains on your vehicle, see “Tire Chains”
in the Index.
Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will clear the area around
your front wheels. Then shift back and forth between REVERSE (R) and a
forward gear (or with a manual transmission, between FIRST
(1) or
SECOND
(2) gear and REVERSE), spinning the wheels as little as possible.
Release the accelerator pedal while you shift, and press lightly
on the
accelerator pedal when the transmission
is in gear. If that doesn’t get you
out after a few tries, you may need to be towed out. Or, you can use your
recovery hooks, if your vehicle has them.
If you do need to be towed out,
see “Towing Your Vehicle” in the Index.
Using the Recovery Hooks
Your vehicle may be equipped with recovery hooks. The recovery hooks are
provided at the front of your vehicle. You may need to use them
if you’re
stuck off-road and need to be pulled to some place where you can continue
driving.

Don’t let someone put in the wrong kind of fluid. For
example, just a few drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake system parts
so
badly that they’ll have to be replaced.
Brake fluid can damage paint, so be careful not to spill brake
fluid on your vehicle.
If you do, wash it off immediately. See
“Appearance Care” in the Index.
Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a high-pitched
warning sound when the brake pads are
worn and new pads are needed. The
sound may come and go or be heard all the time your vehicle
is moving
(except when you are pushing
on the brake pedal firmly).
I NOTICE:
Continuing to drive with worn-out brake pads could result in
costly brake repair.
Some driving conditions or climates may Cause a brake squeal when the
brakes are
first applied or lightly applied. This does not mean something is
wrong with your brakes.
Your rear drum brakes don’t have wear indicators, but if you ever hear a
rear brake rubbing noise, have the rear brake linings inspected. Also, the
rear brake drums should be removed and inspected each time the tires are
removed for rotation or changing. When you have the front brakes replaced,
have
the rear brakes inspected, too.
Brake linings should always be replaced as complete axle sets.

We don’t make tires. Your new vehicle comes with high quality tires made
by a leading tire manufacturer. These tires are warranted by the tire
manufacturers and their warranties are delivered with every new vehicle. If
your spare tire is a different brand than your road tires, you will have a tire
warranty folder from each of these manufacturers.
Inflation - Tire Pressure
The CertificatiodTire label which is on the driver’s door lock pillar, shows
the correct inflation pressures for your tires, when they’re cold. “Cold”
means your vehicle has been sitting for at least three hours or driven no
more than
a mile.

When to Check
Check your tires once a month or more. Also, check the tire pressure of the
spare tire.
How to Check
Use a good quality pocket-type gage to check tire pressure. Simply looking
at the tires will not tell you the pressure, especially if you have radial tires
- which may look properly inflated even if they’re underinflated.
If your tires have valve caps, be sure to put them back on. They help prevent
leaks by keeping out dirt and moisture.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles (10 000 to 13 000 km)
for any signs of unusual wear. If unusual wear is present, rotate your tires as
soon
as possible and check wheel alignment. Also check for damaged tires
or wheels. See “When it’s Time for New Tires” and “Wheel Replacement”
later in
this section for more information.
