proper 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.
Your Cadillac is a passenger vehicle. Trailer towing can
change the way your vehicle performs on the road. The
loads and forces created when trailering subject the
vehicle to significant levels of stress.
Load-pulling components such as the engine, transmission, rear axle, 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

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.
You should always use a weight distributing
(equalizing) hitch if your trailer will weigh more
than 3,000 lbs. (1 362 kg). Consider using sway
control if your loaded trailer will weigh 3,000 lbs.
(1 362 kg) or more. You can ask a hitch dealer
about sway controls.
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.
Trailers that weigh more than
1,000 lbs. (454 kg)
should be equipped with trailer brakes.
Surge brakes may be used on some trailers (e.g., boat
trailers). However, surge brakes do not work well with most sway control devices.
Do not use sway
control devices on trailers equipped with surge brakes.

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. Avoid
continuous operation in mountainous areas that
have grades greater than two percent for longer than
5 miles (8 km).
Change axle lubricant annually or every 7,500 miles
(12
500 km) of trailer towing, whichever occurs first.
Three important considerations have to do with weight:
0 the weight of the trailer,
0 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 2,000 lbs.
(900 kg)
including the load or 7,000 lbs. (3 180 kg) if you have
the optional trailer towing package. But even that can be
too heavy.
It also 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 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.
B A
If you’re using a weight-carrying 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.
The Gross Combined Vehicle Weight (GCVW)
= curb
weight
+ passengers’ weight + cargo + trailer weight.
It should never exceed 7,450 lbs.
(3 1 SO kg) for the
standard vehicle
or 12,100 lbs. (5 490 kg) for the
7,000 lb. towing package.

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:
e
e
e
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 dnving.
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.
Don’t
let the steel in a hitch contact the aluminum on
your bumper. If you do, the two will corrode. You
can use something like paint or plastic tape to
separate the steel and aluminum. The same steel to
aluminum problem can happen with fasteners, too.
Using A Weight-Carrying Trailer Hitch
(Recommended for loaded trailers weighing less than
3,000 lbs. or
1 362 kg.)
The trailer tongue should weigh 10 percent of the
total trailer load (maximum 300 lbs. or 136 kg) or as
specified by the trailer manufacturer to minimize
sway.
Trailers that weigh more than 1,000 lbs. (454 kg)
should be equipped with trailer brakes.
Consider using sway control if your loaded trailer
will weigh 3,000 lbs.
(1 362 kg) or more.
Trailer Hitching Procedure Using A Weight
Distributing (Equalizing) Hitch
(Recommended for loaded trailers weighing 3,000 lbs.
to
7,000 lbs. or 1 362 kg to 3 178 kg.)
Using a weight distributing hitch without disabling the
Electronic Level Control (ELC) system may defeat the
purpose
of the weight distributing hitch. Also, your rear
tires may become overloaded. A weight distributing
hitch should spread the load to all axles. If you use a
weight distributing hitch, always disable the ELC by
following the proper steps.

Disable the Electronic Level Control (ELC) by
pulling the LEVEL CTRL fuse from the underhood
electrical center located on the passenger-side wheel
housing in the engine compartment. Remove the
cover to gain access.
Attach the trailer to the vehicle. The trailer tongue
should weigh
12 percent of the total loaded
trailer weight.
Level the vehicle with the load-leveling spring
bars (equalizers).
Leave the fuse out while towing your trailer.
Once you have completed towing your trailer, be sure
to
reinstall the Electronic Level Control (ELC) fuse.

Use two friction sway controls if your trailer is over
5,000 lbs. (2 270 kg) loaded weight, and/or is over
24 feet (7.3 m) long.
Use at least one friction sway control if your
trailer is over
2,000 lbs. (900 kg) loaded weight,
and consider using one for trailers under
2,000 lbs.
(900 kg).
Trailers that weigh more than
1,000 lbs. (454 kg)
should be equipped with trailer brakes.
Surge brakes work with most weight-distributing
hitches as long as all the equipment is properly
installed. Check with the hitch manufacturer for
advice and installation instructions.
If a trailer is over 5,000 lbs. (2 270 kg), adjust
the vehicle's rear tire pressures to
35 psi (240 Pa)
(cold tire pressure).

Downloaded from www.Manualslib.com manuals search engine Safety Chains Trailer Wiring Harness
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
If your trailer weighs more than 1,000 lbs. (450 kg)
when loaded,
it needs to be equipped with adequate
brakes. Be sure to read and follow the instructions
for
the trailer brakes so you’ll be able to maintain
them properly.
Because you have anti-lock brakes, do not
try to tap into
your vehicle hydraulic brake system.
If you do, both
brake systems won’t work well, or at all.
If your Fleetwood is equipped with the heavy duty
trailering option, a five-wire trailering harness is
located in the trunk. You may have to have it wired
to your vehicle.
These trailer harness color codes should be followed
when connecting to your trailer:
0 White: Direct Trailer Ground for Trailer Lamps
0 Brown: Parking Lamps
Yellow: Left Turn and Stoplamps
Dark Green: Right Turn and Stoplamps
Dark 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.

Downloaded from www.Manualslib.com manuals search engine 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.

Downloaded from www.Manualslib.com manuals search engine 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 Cadillac 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 to a lower gear and
reduce your speed to around
45 mph (70 km/h) to reduce
the possibility of engine and transmission overheating.
If your trailer weighs more than 2,000 lbs. (900 kg), you
should drive in DRIVE
(D or 3) instead of
AUTOMATIC OVERDRIVE (@). This allows the
torque convertor clutch to engage and the transmission
to run cooler.
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. Apply your regular brakes, but don’t shift into
2. Have someone place chocks under the downhill side

of 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) and apply the parking brake.
5. Release the regular brakes.
