0 Reducing vehicle speed.
0 Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are towing a trailer. reduce the amount of
cargo being hauled as soon as it is possible.

Is On Steady" following. If the light is still flashing,
follow the previous steps. and drive the vehicle
to your
dealer
or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently
put fuel into your vehicle'?
If so, reinstall the fuel cap. making sure to fully install
the cap. The diagnostic system can determine
if the fuel cap
has been left off
or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water'?
If so. your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Have you recently changed brands of fuel?
If so. be sure to fuel your vehicle with quality fuel (see
"Fuel"
in the Index). Poor fuel quality will cause your
engine not
to run as efficiently as designed. You may
notice
this as stalling after start-up. stalling when you put
the vehicle into gear, misfiring, hesitation on acceleration
or stumbling
on acceleration. (These conditions may go
away once the engine is warmed up.) This will be detected
by the system and cause the light to turn on.
If you experience one or more of these conditions.
change the fuel brand
you use. It will require at least one
full tank of the proper fuel to turn the light off.
tr none of the above steps have made the light turn off,
have your ciealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic
tools to fix any mechanical or electrical
problems
that may have developed.

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

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.
I NOTICE:

i 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

~ 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.

Downloaded from www.Manualslib.com manuals search engine If You Do Decide To Pull A Trailer
If you do, here are some important points:
a

a
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.
