’ A 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. Pull a

I
in costly repairs not covered by your wan lty. To pull a trailer
correctly, follow the advice
in this secti I.
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 traile\
r adds
considerably to wind resistance, increasing the pulling requirements.
All of that means changes in:
0 Handling
0 Durability
Fuel economy
If You Do Decide To Pull A Trailer
If you do, here are some important points.
There are many different laws 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 can ask a hitch dealer about sway controls.
0 Don’t tow a trailer at all during the first 500 miles (800 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 kmih) and don’t make starts at full throttle.
This helps your engine and other parts
of your vehicle wear in at the
heavier loads.
When towing a trailer, close all windows and set the Electronic
Climate Control System
to “ECON”, “AUTO”, “DEFOG” or
Defroster to assure that the fan is running.
Three important considerations have to do with weight:
1. Weight of the nailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 pounds (450 kg). But even
that can be too heavy.
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
us at Cadillac.
In Canada, write to General Motors of Canada Limited, Customer
Assistance Center,
1908 Colonel Sam Drive, Oshawa, Ontario L1H
8P7.
2. Weight of the Trailer Tongue
When a trailer is connected to your vehicle, the trailer tongue adds
to the weight your vehicle is carrying.
So, remember to subtract the
weight of the trailer tongue from your vehicle’s capacity weight.
212

Downloaded from www.Manualslib.com manuals search engine The trailer tongue (A) should weigh 10% 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.
3. Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the limit for cold tires.
You’ll find these numbers on the Certification label at the rear edge\

of the driver’s door (or see Index under “Tire Loading”). Then be
sure you don’t go over the
GVW limit for your vehicle.
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 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
Index under “Carbon Monoxide”). 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.
213

Downloaded from www.Manualslib.com manuals search engine 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. Follow
the manufacturer’s recommendation for attaching safety chains. \
Always
leave just enough slack
so you can turn with your rig. And, never allow
safety chains
to drag on the ground.
Trailer Brakes
Does your trailer have its own brakes? Be sure to read and follow the
instructions for the trailer brakes
so you’ll be able to install, adjust and
maintain them properly.
Because you have anti-lock brakes, do not try to tap into your vehicle’s
brake system. If you do, both brake systems won’t work well, or at all.
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 so responsive as your vehicle is by
itself.
Before you start, check the trailer hitch and platform, safety chains,
electrical connector, lights, 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 lights 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.
214

Downloaded from www.Manualslib.com manuals search engine 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
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.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a different turn signal
flasher and extra wiring. The green arrows on your instrument panel will
flash whenever
you signal a turn or lane change. Properly hooked up, the
trailer lights 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.
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.
215

Downloaded from www.Manualslib.com manuals search engine If your trailer weighs more than 1,000 pounds (450 Kg) and you have an
automatic transaxle with Overdrive, you may want to drive
in “3” instead
of Overdrive (or, as you need to, a lower gear). This will help your
transmission.
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 “P” (Park) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until
4. Reapply the regular brakes. Then shift into “P” (Park) firmly and
apply your parking brake.
5. Release the regular brakes.
the
chocks absorb the load.
When You Are Ready to Leave Afier 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 scrvice 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, axle lubricant, belts, 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.
