Tire and Loading Information Label
A vehicle specic Tire and Loading Information
label is attached to the center pillar (B-pillar) of your
vehicle. With the driver’s door open, you will nd the
label attached below the door lock post (striker).
The tire and loading information label shows the
number of occupant seating positions (A), and the
maximum vehicle capacity weight (B) in kilograms
and pounds.The Tire and Loading Information label also shows
the size of the original equipment tires (C) and
the recommended cold tire ination pressures (D).
For more information on tires and ination see
Tires on page 462andInation - Tire Pressure
on page 469.
There is also important loading information on the
vehicle Certication/Tire label. It tells you the
Gross Vehicle Weight Rating (GVWR) and
the Gross Axle Weight Rating (GAWR) for the
front and rear axle. See “Certication/Tire Label”
later in this section.
Steps for Determining Correct Load Limit
1. Locate the statement “The combined
weight of occupants and cargo should never
exceed XXX kg or XXX lbs” on your
vehicle’s placard.
2. Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.Example Label

Your vehicle can tow a trailer. To identify the
trailering capacity of vehicle, you should read
the information in “Weight of the Trailer” that
appears later in this section. Trailering is different
than just driving your vehicle by itself. Trailering
means changes in handling, acceleration, braking,
durability, and fuel economy. Successful, safe
trailering takes correct equipment, and it has to
be used properly.
That is the reason for this section. 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. The trailer also 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. See “Hitches”
later in this section.
Do not tow a trailer at all during the rst
500 miles (800 km) your new vehicle is driven.
Your engine, axle, or other parts could be
damaged.
During the rst 500 miles (800 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.
You can use THIRD (3) or, as you need to, a
lower gear when towing a trailer. Operating
your vehicle in THIRD (3) when towing a trailer
will minimize heat buildup and extend the
life of your transaxle.

Three important considerations have to do
with weight:
Weight of the trailer
Weight of the trailer tongue
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.It can also depend on any special equipment that
you have on your vehicle, and the amount of
tongue weight the vehicle can carry. See “Weight
of the Trailer Tongue” later in this section for
more information.
Maximum trailer weight is calculated assuming
only the driver is in the tow vehicle and it has all
the required trailering equipment. The weight
of additional optional equipment, passengers and
cargo in the tow vehicle must be subtracted
from the maximum trailer weight.
Look in the following chart to nd the maximum
trailer weight for your vehicle.
Vehicle Axle Ratio Maximum Trailer Weight *GCWR
Two-Wheel-Drive 3.29 3,500 lbs (1 588 kg) 8,500 lbs (3 856 kg)
Any vehicle without the V92 trailering package or heavy-duty cooling package is limited to a 2,000 lb (907 kg)
trailer rating and a 7,000 lb (3 175 kg) GCWR.
*The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle
and trailer including any passengers, cargo, equipment and conversion. The GCWR for your vehicle should not
be exceeded.
You can ask your retailer for our trailering
information or advice, or you can write us at the

Because your rear axle now weighs 3,100 lbs
(1 406 kg), you can only put 900 lbs (408 kg)
on the rear axle without exceeding RGAWR.
The effect of tongue weight is about 1.5 times the
actual weight. Dividing the 900 lbs (408 kg) by
1.5 leaves you with being able to handle only
600 lbs (272 kg) of tongue weight. Since tongue
weight is usually at least 10 percent of total
loaded trailer weight, you can expect that the
largest trailer your vehicle can properly handle is
6,000 lbs (2 721 kg).
It is important that you make sure your vehicle
does not exceed any of its ratings — GCWR,
GVWR, RGAWR, Maximum Trailer Rating
or Tongue Weight. The only way to be sure you
are not exceeding any of these ratings is to weigh
your vehicle and trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inated to the
upper limit for cold tires. You will nd these
numbers on the Certication/Tire label at the rear
edge of the driver’s door or seeLoading Your
Vehicle on page 391. Then be sure you do not go
over the GVW limit for your vehicle, including
the weight of the trailer tongue.
Hitches
It is 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 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
the bumper.
Will you have to make any holes in the body of
your vehicle when you install a trailer hitch?
If you do, remember to seal the holes later
when you remove the hitch. If you do not seal
them, deadly carbon monoxide (CO) from your
exhaust can get into your vehicle. SeeEngine
Exhaust on page 151. Dirt and water can, too.

CAUTION: (Continued)
This will bring fresh, outside air into
your vehicle. Do not use the climate
control setting for maximum air
because it only recirculates the air
inside your vehicle. SeeClimate
Control System on page 205orDual
Climate Control System on page 209.
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 all trailer hitch parts 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.
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 will need more passing distance up ahead
when you are towing a trailer. And, because
you are a good deal longer, you will need to
go much farther beyond the passed vehicle
before you can return to your lane.

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 specications.
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 apply the brakes, with or without
the vehicle moving, your brakes adjust for wear.
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 Saturn 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.
{CAUTION:
Poorly maintained and improperly used
tires are dangerous.
Overloading your vehicle’s tires can
cause overheating as a result of too
much friction. You could have an
air-out and a serious accident. See
Loading Your Vehicle on page 391.
CAUTION: (Continued)
CAUTION: (Continued)

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 vehicle’s tires are cold. See
Inflation - Tire Pressure on page 469.
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 the tire’s tread is badly worn, or
if your vehicle’s tires have been
damaged, replace them.
