Loading Your Vehicle
Two labels on your vehicle show how much weight it
may properly carry. The Tire
-Loading Information label
found on the driver's door tells you the proper size,
speed rating and recommended inflation pressures for
the tires on your vehicle. It also gives you important
information about the number of people that can be in
your vehicle and the total weight that you can carry.
This weight is called the Vehicle Capacity Weight and
includes the weight of all occupants, cargo and all
options not installed in the factory.
The other label is the Certification label, found on the
rear edge of the driver's door. It tells you the gross
weight capacity of your vehicle, called the Gross
Vehicle Weight Rating (GVWR). The GVWR includes
the weight of the vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle or the Gross
Axle Weight Rating (GAWR) for either the front or
rear axle.
If you do have a heavy load, you should spread it out.
Don't carry more than 203 lbs. (92 kg) in the trunk.

Towing a Trailer
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.
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 ªWeight of the Trailerº
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.

The optional trailer towing package provides the
necessary oil cooler for the DeVille or the DeVille
d'Elegance to tow a trailer heavier than 1,000 lbs.
(450 kg). The DeVille Concours is equipped with this
cooler as standard equipment.
The maximum trailer weight for your vehicle can be
determined from the Gross Combined Vehicle Weight
(GCVW). The GCVW = curb weight + passenger's
weight + cargo weight + trailer weight. The GCVW
should never weigh more than 8, 253 lbs. (3 751 kg)
total loaded vehicle and trailer.

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. See ªLoading Your
Vehicleº in the Index for more information about your
vehicle's maximum load capacity.

6-49 Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not
needed. However, if you notice unusual tire wear or
your vehicle pulling one way or the other, the alignment
may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced. If the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load
-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your vehicle.
CAUTION:
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts and wheel nuts
for replacement.
