Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
Recreational Vehicle Towing
Your vehicle was not designed to be towed with all four
wheels on the ground. If your vehicle must be towed,
see ªTowing Your Vehicleº in the Index.
NOTICE:
Towing your vehicle with all four wheels on the
ground will damage drivetrain components.
To tow your vehicle, follow these steps:
1. Put the front wheels on a dolly.
2. Put the vehicle in PARK (P).
3. Set the parking brake and then remove the key.
4. Clamp the steering wheel in a straight
-ahead position
with a clamping device designed for towing.
5. Release the parking brake.

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.

4-33 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.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) 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 1,000 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.

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.

4-36 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 1,000 lbs. (450 kg), use trailer brakes. Be sure
to follow the instructions that come with the trailer or
from the brake manufacturer.
Be sure to read and follow the instructions for the trailer
brakes so you'll be able to maintain them properly.
Trailer Wiring Harness
If your vehicle is equipped with the 3,000-lb. (1 360 kg)
trailer towing package option, your vehicle comes with a
pouch containing a trailer towing jumper harness and a
trailer stub.
To attach the jumper harness, remove the trunk trim near
the left rear wheel well and connect it to the main body
harness connector which is taped down. The trailer stub
will attach to the trailer and connect to the jumper harness.
These trailer
-wiring harness color codes should be
followed when connecting it to your trailer:
BLACK: Direct trailer ground for trailer lamps.
BROWN: Parking lamps.
YELLOW: Left turn and stoplamps.
GREEN: Right turn and stoplamps.
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.
yellowblue
4-37
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 trailer. 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.
Backing Up
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 Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you're turning with a trailer, make wider turns than
normal. Do this so your trailer won't strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.

4-38 Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a different
turn signal flasher and/or extra wiring. Check with your
dealer. The 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 arrows on your instrument panel
will flash for turns even if the bulbs on the trailer are burned
out. Thus, you may think drivers behind you are seeing your
signal when they are not. It's important to check occasionally
to be sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don't shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
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.
Parking on Hills
CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People can
be injured, and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P).
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
PARK (P) firmly and apply your parking brakes.
5. Release the regular brakes.
