Your Vehicle
Vehicles
with two-wheel drive or the optional electronic
shift transfer case require special modifications before
they can be towed in this manner. Please contact your
dealer
for the towing information that is appropriate for
your particular vehicle.
Vehicles with all-wheel drive
(AWD) can not be towed
in this manner.
The Certificationflire label is found on the driver’s door
edge, above the
door latch. 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 trailer tongue weight, if pulling a trailer.

I A CAUTION:
If you don’t use the correct equipment and drive
properly, you can lose control when you pull
a
trailer. For example, if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
Pull a trailer only if you have followed all the
steps in this section.
Ask your GM dealer for
advice and information about towing a trailer
with your vehicle.

~ with your vehicle.
Every vehicle is ready for $time 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.

a
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 lbs. (900 kg) or less. You should always
use
a sway control if your trailer will weigh more
than
2,000 lbs. (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 kmh) and
don’t make starts
at full throttle. This helps your
engine and other parts
of your vehicle wear in at the
heavier loads.
If you have an automatic transmission, you can 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
buildup and extend the life
of your transmission. If
you have a manual transmission and you are towing
a trailer, it’s better not to use FIFTH (5) gear. Just
drive
in FOURTH (4) gear (or, as you need to, a
lower gear).
Three important considerations have
to do with weight:
0 the weight of the trailer,
the weight of the trailer tongue
and the weight on your vehicle’s tires.
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.
The following chart shows how much your trailer can
weigh, based upon your vehicle model and options.

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.
4-47

Downloaded from www.Manualslib.com manuals search engine A B
If you’re using a weight-carrying hitch, the trailer
tongue
(A) should weigh 10 percent of the total loaded
trailer weight
(B). If you’re using a weight-distributing
hitch, the trailer tongue
(A) should weigh 12 percent 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 upper
limit for cold tires. You’ll find these numbers on the
CertificationRire label
on the driver’s door edge, above
the
door latch, 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:
If you‘ll be pulling a trailer that, when loaded, will
weigh more than
2,000 lbs. (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.

Downloaded from www.Manualslib.com manuals search engine 0 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.
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 Ibs. (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’s brake system can tap
into the vehicle’s
hydraulic brake system
only if
The trailer parts can withstand 3,000 psi
(20 650 kPa) of pressure.
The trailer’s brake system will use less than
0.02 cubic inch (0.3 cc) of fluid from your vehicle’s
master cylinder. Otherwise, both braking systems
won’t work well. You could even lose your brakes.
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
If you have a rear-most window open and you
pull a trailer with your vehicle, carbon monoxide
(CO) could come into your vehicle. You can’t see
or smell
CO. It can cause unconsciousness or
death. (See “Engine Exhaust” in the Index.)
To
maximize your safety when towing a trailer:
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
0 Keep the rear-most windows closed.
If exhaust does come into your vehicle
through
a window in the rear or another
opening, drive with your front, main heating or cooling system on and
with the
fan on
any speed. This will bring fresh,
outside
air into your vehicle. Do not use
MAX A/C because it only recirculates the
air inside your vehicle. (See b‘ Comfort
Controls”
in the Index.) 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.

Downloaded from www.Manualslib.com manuals search engine 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.
Making Turns
I NOTICE:
Making very sharp turns while trailering could
cause the trailer 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.
I’urn 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 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.
4-51

Downloaded from www.Manualslib.com manuals search engine When towing a trailer, the 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 byfilw 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.
if
you have an automatic transmission. you should use
DRIVE (D) when towing a trailer. Operating your
vehicle in DRIVE (D) when towing a trailer will
minimize heat buildup and extend the life
of your
transmission. Or.
if you have a manual transmission. it's
better not to use
FIFTH (5 j gear. just drive in
FOURTH (4) gear (or. as you need to. a lower gear). 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) (or the
rnanual transmission out of gear and the parking brake
applied) 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 ;I hill. If something goes wrong, your ris
could start to move. People can be injured, and both
your vehicle and the trailer
can be damaged.

Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
whiie you:
Start your engine:
Shift into a gear: and
Release the parking brake.
3,. 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.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling
a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transmission fluid (don’t
overfill), engine
oil, axle lubricant, belt. cooling system
and brake adjustment. Each
of these is covered in this
manual. and
the Index will help you find them quickly.
If you’re trailering, it‘s a good idea to review these
sections before you start your
trip.
Check periodically to see that all hitch nuts and bolts
are tight.
