The Certificatioflire
label is found on the
rear edge
of the
driver's door. The
label shows the size
of
your original tires and
the inflation pressures
needed to obtain the
gross weight capacity
of your vehicle.
This is called the GVWR (Gross Vehicle Weight Rating). The GVWR
includes the weight of the vehicle, all occupants, fuel, cargo, and tongue
weight, if pulling a trailer.
The CertificatiodTire label also tells you the maximum weights for the
front and rear axles, called Gross Axle Weight Rating (GAWR).
To find out
the actual loads on your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer
can help you with this. Be sure
to spread out your load equally on both sides of the centerline.
Never exceed the GVWR for your vehicle, or the Gross Axle Weight Rating
(GAWR) for either the front or rear axle.
And, if you do have a heavy load, you should spread it out.
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.

Your warranty does not cover parts or components that fail
because of overloading.
If you put things inside your vehicle - like suitcases, tools, packages, or
anything else
- they will go as fast as the vehicle goes. If you have to stop
or turn quickly, or
if there is a crash, they’ll keep going.
Payload
The Payload Capacity is shown on the Certification/Tire 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. Your dealer can help
you with this.

If your vehicle comes with the Trailering Package, there is also a load rating
which includes the weight
of the vehicle and the trailer it tows. This rating
is called the Gross Combination Weight Rating (GCWR).
When you weigh your trailer, be sure to include the weight of everything
you put in
it. And, remember to figure the weight of the people inside as
part of your load.
Your dealer can help you determine your GCWR.
Add-on Equipment
When you carry removable items, you may need to put a limit on how many
people you carry inside your vehicle. Be sure to weigh your vehicle before
you buy and install the new equipment.

NOTICE:
Pulling a trailer improperly can damage your vehicle and result\

in costly repairs not covered
by your warranty. To pull a trailer
correctly, follow the advice in this part, and see your
GM dealer
for important information about towing a trailer with your
vehicle.
Most vehicles are ready for some trailer towing. If yours was built with
trailering options, as many are, it’s ready for heavier trailers. But trailering
is different than just driving your vehicle by itself. Trailering means changes
in handling, durability, and fuel economy. Successful, safe trailering takes
correct equipment, and it has to be used properly.
That’s the reason for this part. In it are many time-tested, important
trailering tips and safety rules. Many of these are important for your safety
and that
of your passengers. So please read this section carefully before you
pull a trailer.
&!You Do Decide To Pull A Trailer
If you do, here are some important points.
There are many different laws, including speed limit restrictions,
having to do with trailering. Make sure your rig will be legal, not only
where you live but also where you’ll be driving.
A good source for this
information can be state or provincial police.
Consider using a sway control if your trailer will weigh 2,000 pounds
(900 kg) or less. You should always use a sway control if your trailer
will weigh more than
2,000 pounds (900 kg). You can ask a hitch
dealer about sway controls.

Don’t tow a trailer at all during the first 500 miles (800 km) your new
vehicle is driven. Your engine, axle or other parts could be damaged.
Then, during the first
500 miles (800 km) that you tow a trailer, don’t
drive over
50 mph (80 kdh) and don’t make starts at full throttle. This
helps your engine and other parts
of your vehicle wear in at the heavier
loads.
You should use DRIVE (D) (or, as you need to, a lower gear) when
towing a trailer. Operating your vehicle in
DRIVE (D) when towing a
trailer will minimize heat build-up and extend the
life of your
transmission.
Three important considerations have to do with weight:
Weight of the Trailer
How heavy can a trailer safely be?
It depends
on how you plan to use your rig. For example, speed, altitude,
road grades, outside temperature and how much your vehicle is used to pull
a trailer are
all important. And, it can also depend on any special equipment
that you have on your vehicle.
You can ask your dealer for our trailering information or advice, or you can
write us
at the address listed in your Warranty and Owner Assistance
Information Booklet.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight to measure
because it affects the total or gross weight
of your vehicle. The gross vehicle
weight (GVW) includes the curb weight
of the vehicle, any cargo you may
carry in it, and the people who will be riding in the vehicle. And if you will
tow
a trailer, you must add the tongue load to the GVW because your
vehicle will be carrying that weight, too. See “Loading Your Vehicle” in the
Index for more information about your vehicle’s maximum load capacity.
4-27

Downloaded from www.Manualslib.com manuals search engine A
If you’re using a “dead-weight” hitch, the trailer tongue (A) should weigh
10% of the total loaded trailer weight (B). If you have a
“weight-distributing” hitch, the trailer tongue
(A) should weigh 12% of the
total loaded trailer weight
(B).
After you’ve loaded your trailer, weigh the trailer and then the tongue,
separately,
to see if the weights are proper. If they aren’t, you may be able to
get them right simply by moving some items around in the trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the limit for cold tires. You’ll find
these numbers on the Certification label at the rear edge
of the driver’s door
or see “Tire Loading” in
the Index. Then be sure you don’t go over the
GVW limit for your vehicle, including
the weight of the trailer tongue.
Hitches
It’s important to have the correct hitch equipment. Crosswinds, large trucks
going by, and rough roads are
a few reasons why you’ll need the right hitch.
Here are some rules to follow:
0 If you’ll be pulling a trailer that, when loaded, will weigh more than
2,000 pounds (900 kg), be sure to use a properly mounted,
weight-distributing hitch and sway control
of the proper size. This
equipment is very important for proper vehicle loading and good
handling when you’re driving.
Will you have to make any holes in the body of your vehicle when you
install a trailer hitch? If you do, then be sure to seal the holes later
when you remove the hitch. If
you don’t seal them, deadly carbon
monoxide (CO) from your exhaust can get into your vehicle (see
“Carbon Monoxide”
in the Index). Dirt and water can, too.
4-28

Downloaded from www.Manualslib.com manuals search engine Safety Chains
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 brake system can tap into your vehicles’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.

Downloaded from www.Manualslib.com manuals search engine 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.
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.
4-30

Downloaded from www.Manualslib.com manuals search engine 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.
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.

Downloaded from www.Manualslib.com manuals search engine 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 km/h) to reduce the possibility of engine and transmission overheating.
When towing at high altitude
on steep uphill grades, consider the following:
Engine coolant will boil at
a lower temperature than at normal altitudes. If
you turn your engine off immediately after towing at high altitude on steep
uphill grades, your vehicle may show signs similar to engine overheating.
To avoid this, let the engine run while parked (preferably on level ground)
with the automatic transmission
in PARK (P) for a few minutes before
turning the engine off. If you do get the overheat warning, see “Engine
Overheating”
in the Index.
Parking on Hills
You really should not park your vehicle, with a trailer attached, on a hill. If
something goes wrong, your rig could start to move. People can be injured,
and both your vehicle and the trailer can be damaged.
But if
you ever have to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into PARK (P) yet. Turn your
wheels into the curb when facing downhill and away from the curb
when facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb the load.
4. Reapply the regular brakes, Then apply your parking brake, and shift to
5. Release the regular brakes.
PARK (P).
When You Are Ready to Leave After Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
