Only)
In very cold weather, 0°F (- I 8 O C) or colder, the engine
coolant heater can help.
You’ll get easier starting and
better fuel economy during engine
warm-up. Usually,
the coolant heater should be plugged in a minimum
of
four hours prior to starting your vehicle.
To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
I A CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock.
Also, the wrong
kind
of extension cord could overheat and cause
a fire.
You could be seriously injured. Plug the
cord into
a properly grounded three-prong
110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.

THIRD (3): This position is also used for normal
driving however, it offers more power and lower fuel
economy than OVERDRIVE
(@).
Here are examples for using THIRD (3) instead of
OVERDRIVE (a):
0 When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
0 When going down a steep hill.
SECOND (2): This position gives you more power. You
can use SECOND
(2) on hills. It can help control your
speed as
you go down steep mountain roads, but then
you would also want to use your brakes
off and on.
I NOTICE:
r
~~
Don’t shift into SECOND (2) unless you are going
slower than
65 mph (105 km/h), or you can
damage your engine. FIRST
(1): This
position gives you even more power
than SECOND
(2). You can use it on very steep hills,
or in deep snow or mud. (If the shift lever is put in
FIRST (l), the transaxle won’t shift into first gear
until the vehicle is going slowly enough.)
NOTICE:
If your front wheels can’t rotate, don’t try to
drive. This might happen if you were stuck in
very deep sand or mud or were
up against a solid
object.
You could damage your transaxle.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could cause overheating and damage
the transaxle.
Use your brakes to hold your
vehicle in position on
a hill.

I A CAUTION:
If your hand or arm is in the way of the pedal,
you could be hurt. The pedal springs back
quickly. Keep your hand and arm away when
you use the manual release lever.
I
NOTICE:
Driving with the parking brake on can cause
your rear brakes to overheat.
You may have to
replace them and you could also damage other
parts of your vehicle.
Shifting Into PARK (P)
1 A CAUTION:
If you are towing a trailer and are parking on a hill, see
“Towing a Trailer” in the Index. This section shows
what to do first to keep the trailer from moving. It
can be dangerous to’get out
of your vehicle if
the shift lever is not fully in
PARK (P) with the
parking brake firmly set. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly.
You or others could be
injured. To be sure your vehicle won’t move, even
when you’re on fairly level ground, use the steps
that follow.
If you’re pulling a trailer, see
“Towing
a Trailer” in the Index.

6. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in
PARK (P).
Leaving Your Vehicle With the Engine
Running
1 A CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly
if the shift lever is not fully in PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire.
You or others could
be injured. Don’t leave your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK
(P) and your
parking brake
is firmly set before you leave it. After
you’ve moved the shift lever into the PARK
(P)
position. hold the regular brake pedal down. Then, see
if you can move the shift lever away from PARK (P)
without first pulling it toward you (or, if you have the
console shift lever, without first pressing the button).
If
you can. it means that the shift lever wasn’t fully locked
into
PARK (a).

Light
This red light tells you that
the engine has overheated.
You should stop the car and
turn the engine off as soon
as possible.
A warning
chime should also sound if
this light comes on.

SERVICE
ENGINE
SOON
Your Cadillac is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD
I1 (.On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life
of the vehicle, helping to produce a cleaner
environment. (In Canada,
OBD I1 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE SOON
light comes on to indicate that there is a problem and
service is required. Malfunctions often will be indicated
by the system before any problem is apparent, which
may prevent more serious damage to your vehicle. This
system is also designed
to assist your service technician
in correctly diagnosing any malfunction.

level sensing system does not check for actual oil level
if the engine has been off for
a short period of time, and
the oil level is never sensed while the engine is running.
If the CHECK OIL LEVEL message appears, and your
vehicle has been parked on level ground with the engine
off
for at least 30 minutes, the oil level should be
checked by observing the
oil dipstick. Prior to checking
the oil level be sure the engine has been off for five
minutes and your vehicle
is on a level surface. Then
check the dipstick and add oil if necessary. See “Engine
Oil” in the Index.

Turn Signals When Towing a Trailer
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.
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.
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 brake.
Release the regular brakes.
