Downloaded from www.Manualslib.com manuals search engine A CAUTION:
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.
0 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
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 trailer only if you have followed all the
steps in this section. Ask your Cadillac dealer for
advice and information about towing
a trailer
with your vehicle.
I NOTICE:
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered by
your warranty.
To pull a trailer correctly, follow
the advice in this part, and see your Cadillac
dealer for important information about towing
a
trailer with your vehicle.

If your vehicle is equipped with the 3,666-&. (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:
0 WHITE: Direct trailer ground for trailer lamps.
0 BROWN: Parking lamps.
0 YELLOW Left turn and stoplamps.
0 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.
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.

you’ll need to store the flat tire in your trunk. Use the
following procedure to secure the flat tire in the trunk.
Put the flat tire in the trunk
so the side that faces out
when it
is on the vehicle is facing down. The full-size
tire will not fit down into the well. Place
it so the front is
in the well and the rear is out of the well.

Operating the engine with the air cleaner off can
cause you or others
to be burned. The air cleaner
not only cleans the
air, it stops flames if the
engine backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it off, and be careful working on the engine with
the
air cleaner off.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the
air cleaner in place when you’re driving.
