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 GVWR
(Gross Vehicle Weight Rating). 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.
I A CAUTION:
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR.
If you do, parts on your vehicle can
break, or it can change the
way your vehicle
handles. These could cause you to lose control.
Also, overloading can shorten the life
of
your vehicle.
I NOTICE:
Your warranty does not cover parts or
components
that fail because of overloading.
If you put things inside your vehicle
-- like suitcases,
tools, packages or anything else
-- they will go as fast as
the vehicle goes. If you have to stop
or turn quickly, or
if there is
a crash, they’ll keep going.

Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or in
a crash.
Put things in the trunk of your vehicle. In a
trunk, put them
as far forward as you can.
Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle
so that some of them are
above the tops of the seats.
Don’t leave an unsecured child restraint in
your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Electronic Level Control
This feature keeps the rear of your vehicle level as the
load changes. It’s automatic
-- you don’t need to
adjust anything.
Towing a Trailer
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.

Downloaded from www.Manualslib.com manuals search engine 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,
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 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 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.

Downloaded from www.Manualslib.com manuals search engine Three important considerations have to do with weight:
the weight of the trailer,
the weight of the trailer tongue
0 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) if
you have a DeVille or a DeVille d’Elegance without the optional trailer towing package. If you have a DeVille
Concours, DeVille or DeVille d’Elegance with the
optional trailer towing package, the maximum trailer
weight should never be more than 3,900 lbs.
( 1 773 kg).
These are total maximum weights including the load.
But even that can be too heavy.
If you tow more than 1000 lbs. (450 kg), use trailer
brakes. Be sure to follow the instructions that come with
the trailer or from the brake manufacturer.
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
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.

Downloaded from www.Manualslib.com manuals search engine 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 “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 percent of the total loaded
trailer weight
(B). If you have 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 limi\
t
for cold tires. You’ll find these numbers on the
Tire-Loading Information 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.

Downloaded from www.Manualslib.com manuals search engine 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:
0
0
0
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.
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.
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
Because you have anti-lock brakes, don’t try to tap into
your vehicle’s hydraulic brake system. If you do, both
brake systems won’t work well, or at
all. If you tow
more than
1000 lbs. (450 kg), use trailer brakes. Be sure
to follow the instructions that come with the trailer or
from brake manufacturer.
Be sure to read and follow the instructions for the trailer
brakes
so you’ll be able to maintain them properly.

Downloaded from www.Manualslib.com manuals search engine Trailer Wiring Harness
If your vehicle is equipped with the 3,000-lb. (1 360 kg)
trailer towing package option, you will have
a wiring
harness located under the
trunk trim. The harness is a
five-wire harness, with connector.
These trailer-wiring harness color codes should be
followed when connecting it
to your trailer:
WHITE: Direct trailer ground for trailer lamps.
BROWN: Parking lamps.
0 YELLOW Left turn and stoplamps.
GREEN: Right turn and stoplamps.
0 BLUE: Auxiliary circuit.
Driving with a Trailer
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.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a tr$ler. This
can help you avoid situations that require heavy braking
and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal \
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.

Downloaded from www.Manualslib.com manuals search engine Backing Up Tbrn Signals When Towing a Trailer
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back
up slowly and, if
possible, have someone guide you.
Making arris
When you tow a trailer, your vehicle may need a different turn signal flasher and/or extra wiring. Check
with your Cadillac dealer. The green arrows on your
instrument panel will flash whenever you signal a turn
or lane change. Properly hooked
up, the trailer lamps
will also flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the green arrows on your instrument panel will flash for turns even
if the bulbs on
the trailer are burned out. Thus, you may think drivers NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could
be damaged. Avoid

important to check occasionally to be sure the trailer
bulbs are still working.
making very sharp turns while trailering. Driving On Grades
Reduce speed and shift to a lower gear before you start
When you’re turning with
a trailer, make wider turns down a long or steep downgrade. If you don’t shift
than normal. Do this
so your trailer won’t strike soft down, you might have to use your brakes so much that
shoulders, curbs, road signs, trees
or other objects. they would get hot and no longer work well.
Avoid jerky or sudden maneuvers. Signal well
in advance. On
a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) or less to reduce the
possibility
of engine and transaxle overheating.
