Downloaded from www.Manualslib.com manuals search engine Move the switch to ei&r LO or HI to turn on the heating element in the
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.

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

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.
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.
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:
Apply your regular brakes, but do not shift into “P” (Park).
0 Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the regular brakes until
Reapply the regular brakes. Then shift into “P” (Park) firmly and
the
chocks absorb the load.
apply your parking brakes.
Release the regular brakes.
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.

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