Three important considerations have to do with weight: 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?
If you have a DeVille without the optional h-ailer towing
package,
the maximum trailer weight is 1,OOO lbs. (450 kg).
If you have a DeVille Concours or a DeVille with the
optional trailer towing package, the maximum trailer weight should never be more than
3,900 lbs. (1 773 kg)
total including the load. But even that can be too heavy.
The optional trailer towing package. provides the
necessary oil cooler for the DeVille to
tow a trailer
heavier than 1,OOO lbs.
(450 kg). The 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 + trailer weight, should never weigh more
than
8,200 lbs. (3 727 kg) total loaded vehicle and trailer.
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, You
can ask your dealer for our trailering information or
advice, or you can write

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight
to measure because it affects the total capacity
weight
of your vehicle. The capacity weight 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 will tow a trailer, you must subtract the tongue load
from your vehicle’s capacity weight 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.

If you’re using a “dead-weight” hitch, the trailer
tongue
(A) should weigh 10% of the total loaded trailer
weight
(B). If you have a “weight-distributing” hitch,
the trailer tongue
(A) should weigh 12% 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
recommended .pressure for cold tires. You’ll find these numbers on the Certification 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:
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.

0 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.
0 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.
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.
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.
Be sure to read and follow the instructions for the trailer
brakes
so you’ll be able to maintain them properly.

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, 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.
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 expenence.
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 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 Thms
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.
Downloaded from www.Manualslib.com manuals search engine lhrn Signals When Towing a nailer
When you tow a trailer, your vehicle may need a
different
turn signal flasher and 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
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.
I€ 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 b/h) or less to reduce the
possibility
of engine and transaxle overheating.
If your vehicle weighs more
than 1,OOO lbs. (450 kg),
you may want to drive in
THIRD (3) instead of
OVERDRIVE (@).

Parking on Hills
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.
2.
3.
4.
5.
Apply your regular brakes, but do not shift into
PARK (P).
Have someone place chocks under the trailer wheels.
When the wheel chocks are
in place, release the
regular brakes until the chocks absorb the load.
Reapply
the regular brakes. Then shift into
PARK (P) firmly and apply your parking brakes.
Release the regular brakes.
When You Are-Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while
you:
Start your engine;
Shift into a gear; and
Be sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.

Downloaded from www.Manualslib.com manuals search engine Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you find them quickly.
If you’re trailering, it’s
a good idea to review these sections before you start
your trip.
Check periodically
to see that all hitch nuts and bolts
are tight.
