Towing a Trailer
{CAUTION:
If you do not 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. You may also damage your
vehicle; the resulting repairs would not be
covered by your warranty. Pull a trailer only if
you have followed all the steps in this section.
Ask your dealer for advice and information
about towing a trailer with your vehicle.
Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. 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,
rear axle, 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.
•Do not tow a trailer at all during the first 500 miles
(805 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.

•Then, during the first 500 miles (805 km) that you
tow a trailer, do not drive over 50 mph (80 km/h)
and do not 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.
Do not 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 (454 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 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 tow a trailer, you must add the
tongue load to the GVW because your vehicle will
be carrying that weight, too. SeeLoading Your Vehicle
on page 4-32for more information about your
vehicle’s maximum load capacity.
If you are using a weight-carrying hitch or a
weight-distributing hitch, the trailer tongue (A) should
weigh 10 to 15 percent of the total loaded trailer
weight (B).After you have loaded your trailer, weigh the trailer and
then the tongue, separately, to see if the weights are
proper. If they are not, 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 will find these numbers on the
Tire-Loading Information label, SeeLoading Your
Vehicle on page 4-32. Then be sure you do not 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 will need the right hitch. Here
are some rules to follow:
•The rear bumper on your vehicle is not intended for
hitches. Do not attach rental hitches or other
bumper-type hitches to it. Use only a frame-mounted
hitch that does not attach to the bumper.
•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. SeeEngine Exhaust on page 2-25. 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
Because your vehicle has anti-lock brakes, do not try to
tap into your vehicle’s hydraulic brake system. If you
do, both brake systems will not work well, or at all.
Be sure to read and follow the instructions for the trailer
brakes so you’ll be able to install, adjust and maintain
them properly.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you will 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.

{CAUTION:
The brake wear warning sound means that
soon your brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
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.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to Saturn torque specifications.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your retailer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you make a moderate brake stop, your
brakes adjust for wear. If you rarely make a moderate or
heavier stop, then your brakes might not adjust correctly.
If you drive in that way, then — very carefully — make a
few moderate brake stops about every 1,000 miles
(1 600 km), so your brakes will adjust properly.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top-quality brake parts.
When you replace parts of your braking system — for
example, when your brake linings wear down and you
need new ones put in — be sure you get new approved
Saturn replacement parts. If you do not, your brakes may
no longer work properly. For example, if someone puts in
brake linings that are wrong for your vehicle, the balance
between your front and rear brakes can change — for the
worse. The braking performance you have come to
expect can change in many other ways if someone puts
in the wrong replacement brake parts.

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service,
see your Saturn Warranty booklet for details. For
additional information refer to the tire manufacturer’s
booklet included with your vehicle’s owner manual.{CAUTION:
Poorly maintained and improperly used tires are
dangerous.
Overloading your tires can cause
overheating as a result of too much friction.
You could have an air-out and a serious
accident. SeeLoading Your Vehicle on
page 4-32.
Underinated tires pose the same danger
as overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold. SeeInflation - Tire
Pressure on page 5-54.
Overinated tires are more likely to be
cut, punctured or broken by a sudden
impact — such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
