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

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.

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.
Engine Cooling When Trailering
Your cooling system may temporarily overheat during
severe operating conditions such as:
Climbing grades steeper than four percent at
temperatures above
90°F (32°C) with a loaded
vehicle and trailer.
Stopping after high-speed driving.
Idling for long periods in stop-and-go traffic.
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 transmission fluid (don’t
overfill), engine oil, axle lubricant, 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.

battery with a negative ground system.
NOTICE:
If the other system isn’t a 12-volt system with a
negative ground, both vehicles can be damaged.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your Cadillac, and the bad.grounding could
damage the electrical systems.
You could be injured if the vehicles roll. Set the
parking brake firmly on each vehicle. Shift into
PARK (P).
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette lighter. Turn off all lamps that aren’t needed as well
as radios. This will avoid sparks and help save both
batteries. In addition, it could save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. Open the hoods and locate the batteries.
Find the positive
(+) and negative (-) terminals on
each battery.

cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.

If there seems to be no leak, with the engine on, check to
see if the electric engine fan(s) are running. If the engine
is overheating, both fan(s) should be running.
If they
aren’t, your vehicle needs service.

Although the compact spare tire was fully inflated when
your vehcle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi
(420 Wa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure your
spare tire is correctly inflated. The compact spare is
made to perform well at posted speed limits for
distances up to
3,000 miles (5 000 km), so you can
finish your trip and have your full-size tire repaired
or
replaced where you want. Of course, it’s best to replace
your spare with a full-size tire as soon as you can. Your
spare will last longer and be in good shape in case you

Filling Your Tank
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don’t smoke if you’re near gasoline or refueling
your vehicle. Keep sparks, flames, and smoking
materials away from gasoline.
Your vehicle has a locking fuel filler door.
The cap is behind the license plate. Pull down on the top
of the license plate bracket door
to open.

Downloaded from www.Manualslib.com manuals search engine When you put the cap back on, turn it to the right until
you hear at least three clicks. Make sure you fully install
the cap.
The diagnostic system can determine if the fuel
cap has been left off or improperly installed. This would
allow fuel to evaporate into the atmosphere. See
“Malfunction Indicator Lamp” in the Index.
NOTICE:
If you need a new cap, be sure to get the right
type. Your dealer can get one for you.
If you get
the wrong type,
it may not fit or have proper
venting, and your fuel tank and emissions system
might be damaged.
Checking Things Under the Hood
A CkmON’:
An electric fan under the hood can start up and
injure you even when the engine
is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop or spill
things that will burn onto a hot engine.
