seat.
This feature is designed primarily for use on damp and chilly days. The
LO setting warms the seatback and cushion until the seat approximates
body temperature.
On colder days, the HI setting heats the seats to an
even higher temperature. To prevent uncomfortable overheating of the
seats, the heating elements are thermostatically regulated to
automatically maintain the temperature at the selected setting.
A telltale
light in the control switch reminds you that the heating system is in use.
To preserve the battery, the heated seats can only be used when the
ignition is turned
on, and are deactivated when the ignition is turned off.
Head Restraints
Slide the head restraint up 6r ,down so that the top of the restraint is
closest
to the top of your ears.
This position reduces the chance
of a neck injury in a crash. The head
restraints tilt forward and rearward also.

BLOCK HEATER) (OPTION)
(CANADA ONLY)
In very cold weather, O°F (-1S”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 outlet.
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 fie. You could be seriously injured. Plug
the cord into
a properly grounded three-prong 110-volt outlet. If
the cord won’t reach, use a heavy-duty three-prong extension
cord rated for at least 15 amps.
NOTICE:
After you’ve used the coolant heater, be sure to store the cord as
it was before to keep it away from moving engine parts.
If you
don’t, it could be damaged.
How long should
you keep the coolant heater plugged in? The answer
depends on the weather, the kind
of oil you have, and some other things.
Instead
of trying to list everything here, we ask that you contact a Cadillac
dealer in the area where you’ll be parking your vehicle. The dealer can
give you the best advice for that particular area.

This position gives you more power but lower fuel economy. You can
use
“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.
NOTICE:
Don’t drive in “2” (Second Gear) for more than 5 miles (8 km),
or at speeds over 55 mph (88 km/h), or you can damage your
transaxle. Use
“@” or “3” as much as possible.
Don’t shift into
“2” unless you are going slower than 65 mph
(105 km/h), or you can damage your engine.
1 (First Gear)
This position gives you
even more power (but lower fuel economy)
than
“2.” You can use it on very steep hills, or in deep snow or mud. If
the selector lever is put in “1,” 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 overheat and
damage the transaxle. Use your brakes to hold your vehicle in
position on
a hill.

Don’t put papers or other flammable things into your ashtrays.
Hot cigarettes or other smoking materials could ignite them,
causing
a damaging fire.
Cigarette Lighter
It’s near the ashtray. To use the lighter just push it in all the way and let
go. When it’s ready, it will pop out in by itself.
NOTICE:
Don’t hold a cigarette lighter in with your hand while it is
heating.
If you do, it won’t be able to back away from the
heating element when it’s ready. That can make it overheat,
damaging the lighter and the heating element.

Downloaded from www.Manualslib.com manuals search engine If the light stays on, turn the ignition off. Or, if the light comes on when
you’re driving, stop as
soon as possible and turn the ignition off. Then
start the engine again to reset the system. If the light still stays on, or
comes
on again while you’re driving, your Cadillac needs service. If the
regular brake system warning light isn’t on,
you still have brakes, but you
don’t have anti-lock brakes. If the regular brake system warning light is
also on, you don’t have anti-lock brakes and there’s a problem with your
regular brakes. See “Brake System Warning Light” earlier
in this part.
The anti-lock brake system warning light may also come on when you are
driving with a compact spare tire. If this happens, the light means you
won’t have anti-lock until you replace the compact spare with a full-size
tire.
If the warning light stays on after you replace the compact spare with
a full-size tire, or if it comes on again when you’re driving, your Cadillac
needs service.
Engine Temperature Warning Light (Canadian Only)
This light tells you that
your engine has
overheated. You should
stop the car and idle the
engine as soon as
possible. A warning
chime should also sound
if this light comes on. As
a check, the light should
come on for a few
seconds when
you start
your engine.
HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road,” this manual shows what to do. See “Engine
Overheating” in the Index.

This message will appear for a few seconds indicating that you need
washer solvent.
CHANGE OIL SOON - 40
This message will appear when your engine oil is less than 10 percent or
the mileage since the last
oil change is more than 6750 miles.
CHANGE ENGINE OIL - 82
This means that the life of your engine oil has expired and it should be

126°C (259OF). To avoid added strain on a hot engine, turn off your
Climate Control system, and stop and allow your vehicle to idle until it
cools down or the message
is removed. If it does not cool down, turn off
your engine and have it serviced before driving it again. Severe engine
damage can result from an overheated engine. See “Engine Overheating”
in the Index.
ENGINE HOT - A/C COMPRESSOR OFF - 16
This message will appear when the Climate Control is in “Auto” or
“Defrost” and the engine coolant is hotter than the normal operating
temperature.
To avoid added strain on a hot engine the air conditioning
compressor is automatically turned
off. When that happens, air
conditioned air is not delivered.
If the coolant temperature returns to
normal, the
A/C operation returns to normal.
