Your vehicle can tow a trailer. To identify what the
vehicle trailering capacity is for your vehicle, you
should read the information
in “Weight of the Trailer”
that appears later in this section. 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.
Load-pulling components such as the engine, transaxle,
wheel assemblies and tires
are forced to work harder
against the drag of the added weight. The engine is
required to operate at relatively higher speeds and under
greater loads, generating extra heat. What’s more, the
trailer adds considerably to wind resistance, increasing
the pulling requirements.
If 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. You can ask a hitch
dealer about sway controls.
Don’t tow a trailer at all during the first 1,000 miles
(1 600 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 km/h) and
don’t make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at the
heavier loads.
Obey speed limit restrictions when towing a trailer.
Don’t drive faster than the maximum posted speed
for trailers (or no more than
55 mph (90 km/h)) to
save wear
on your vehicle’s parts.

Three important considerations have to do with weight:
the weight of the trailer, the weight of the trailer tongue
and the total weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs. (450 kg). But
even that can be too heavy.
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.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight to measure because
it affects the total capacity
weight of your vehicle. The capacity weight 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 subtract the tongue
load from your vehicle’s capacity weight 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.

A B
If you’re using a weight-carrying 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.

Be sure your vehicle’s tires are inflated to the
recommended pressure for cold tires. You’ll find these
numbers on the Certification label at the rear edge
of the
driver’s door or see “Loading Your Vehicle” in the
Index. Then be sure you don’t go over the
GVW limit
for your vehicle, including the weight of the trailer
tongue.
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
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.
The bumpers on your vehicle are not intended
for hitches.
Do not attach rental hitches or other
bumper-type hitches
to them. Use only a
frame-mounted hitch that does not attach to
* : bumper.

Safety Chains Driving with a Trailer
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
Does your trailer have its own brakes?
Be sure to read and follow the instructions for the trailer
brakes
so you’ll be able to install, adjust and maintain
them properly.
Because you have anti-lock brakes, do not try to tap into
your vehicle’s brake system.
If you do, both brake
systems won’t work well, or at all. 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.

12. Try to start the vehicle with the dead battery. If
it won’t start after a few tries, it probably needs
service.
13. Remove the cables in reverse order to prevent electrical shorting. Take care that they don’t touch
each other or any other metal.

Towing Your Vehicle
Try to have a GM dealer or a professional towing
service tow your vehicle.
If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like fog
lamps, aero skirting, or special tires and wheels, these
instructions and illustrations may not be correct.
Before you do anything, turn on the hazard warning
flashers.
When you call, tell the towing service:
That your vehicle can only be towed from the front
0 That your vehicle has front-wheel drive.
0 The make, model and year of your vehicle.
0 Whether you can still move the shift lever.
If there was an accident, what was damaged.
When the towing service arrives, let the tow operator
know that this manual contains detailed towing
instructions and illustrations. The operator may want to
see them. with

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, and 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.
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.
I /d CAUTIO,
Changing a tire can cause an injury. The vehicle
can slip
off the jack and roll over you or other
people.
You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks
at the front and rear of the
tire farthest away from the one being changed.
That would be the tire on the other side of the
vehicle, at the opposite end.

Removing the Spare Tire and Tools
The following steps will tell you how to use the jack and
change a tire. The equipment you'll
need is in the trunk.
Instructions for changing your tires
are on the inside of
the tire cover. You can rest the cover near you for easy
reference while you change the tire.

Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire
or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire and its wheel together.
ITICE:
~
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t use tire chains on your
compact spare.
If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you must use caution.
If you let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transaxle or other parts
of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels
as little as possible. Don’t
spin the wheels above
35 mph (55 km/h) as shown
on the speedometer.
ProCarManuals.com

NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well
as the tires. If you spin the wheels
too fast while shifting your transaxle back and
forth, you can destroy your transaxle.
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. You should turn
your traction control system off. (See “Traction Control
System” in the Index.) Then shift back and forth
between REVERSE
(R) and a forward gear, spinning the
wheels as little
as possible. Release the accelerator pedal
while you shift, and press lightly on the accelerator
pedal when the transaxle is in gear. If that doesn’t get
you out after
a few tries, you may need to be towed out.
If you do need to be towed out, see “Towing Your
Vehicle” in the Index.

Headlamp Aiming
Your vehicle has the composite headlamp system. These
headlamps have horizontal and vertical aim indicators.
The aim has been pre-set at the factory and should need
no further adjustment.
If your vehicle is damaged in an accident and the
headlamp aim seems to
be affected, see your Aurora
retailer. Headlamps on damaged vehicles may require
recalibration
of the horizontal aim by your Aurora retailer.
To check the aim, the vehicle should be properly
prepared as follows:
The vehicle must have all four tires on a perfectly
level surface.
0 The vehicle should not have any snow, ice, or mud
attached to it.
There should not be any cargo or loading of vehicle,
except
it should have a full tank of gas and one
person or
160 pounds (75 kg) on the driver’s seat.
Tires should be properly inflated.
NOTICE:
To make sure your headlamps are aimed
properly, read all the instructions before beginning. Failure to follow these instructions
could cause damage to headlamp parts.
State inspection stations will allow a vertical reading of
plus
0.76 degrees or minus 0.76 degrees from the center
of the bubble.
It is recommended that the upper limit not exceed plus
0.4 degrees from the center of the bubble. Other drivers
may flash their bright lights at you if your adjustment is
much above plus
0.4 degrees.
If you find that the headlamp aiming needs adjustment,
follow these steps:
