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

Downloaded from www.Manualslib.com manuals search engine This section tells you how to make your air system work
for
you. Your Electronic Climate Control (ECC) system
uses ozone-friendly
R- 134a refrigerant.
With the
ECC system. you can control the heating,
cooling and ventilation in your Cadillac. Your vehicle
also has a flow-through ventilation system described
later
in this section. The
button with the fan symbol adjusts the fan speed.
Press the up arrow to increase fan speed and the down
arrow to decrease fan speed.
The TEMPIAUTO knob adjusts the air temperature
coming through the system. Turn the TEMP/AUTO
knob clockwise to increase the temperature and
counterclockwise to decrease the temperature. Press
the
TEMWAUTO knob to put the system in the
automatic mode.
With this dual-zone feature, the right front passenger can
control the temperature
of air for hidher own zone. The
passenger can select a four degree warmer or cooler
temperature from the driver's setting.
To turn the system
on, press the PASSTEMP button. Press the up arrow to
increase the temperature and press the down arrow to
decrease
the climate setting. Pressing the OFF button
will
turn off the dual-zone function.

Downloaded from www.Manualslib.com manuals search engine To-find your comfort zone, start with the 75°F (24°C)
setting and allow about 20 minutes for the system to
regulate. Turn the
TEMP/AUTO knob to adjust the
temperature if necessary.
If you choose 60°F ( 1 6"C),
the system will remain at that maximum cooling setting
and will
not regulate fan speed. If you choose the
temperature of
90°F (32'C), the system will remain at
that maximum heating setting and will not regulate fan
speed. Choosing either maximum setting will not cause
the system
to heat or cool any faster.
With
the: automatic setting, the air conditioning
compressor automatically cycles
when needed to cool
the air. In cold weather, when the system senses the need
for heat, the airflow will be directed out the floor
outlets.
As the interior temperature approaches a desired
setting, the blower speed will decrease.
To maintain
interior comfort, the airflow may move
to the instrument
panel air outlets and floor outlets (bi-level mode). On
bright
sunny days in cold weather. the airflow may come
out
of the air conditioning outlets (AC mode) to
maintain comfort and prevent stuffiness.
If your vehicle is sitting out on a hot day and you have it
set on AUTO, the air will first flow out the floor air
outlets for
a few seconds. That is normal. This is to
expel hot air from the air outlets. As the air
is cooled,
the airflow will move through the air conditioning
outlets. If you start your vehicle with the fan setting on
HI, it will skip the air conditioning purge.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan
until warm air is available.
The length
of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started.
As the coolant warms
up, the blower fan speed will gradually increase and
air will flow from the heater outlets, with some airflow
to the windshield to prevent fogging under most
normal conditions.
If you leave your vehicle, the system will remember the
control setting the next time
you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation, whereas,
DEFROST will change
to automatic operation when the ignition is shut off and
then turned back
on.

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
0 Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transaxle. These parts can work hard
on
mountain roads.
Know how to go down hills. The most important
thing to know is this:
let your engine do some of the
slowing down. Shift to a lower gear when
you go
down a steep or long hill.
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have to
do
all the work of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down
a hill.
You could crash. Always have your engine running
and your vehicle in gear when
you go downhill.
~
If you don’t shift down, your brakes could get so
hot that they wouldn’t work well. You would then
have
poor braking or even none going down a hill.
I’ou could crash. Shift down to let your engine
assist your brakes on a steep downhill slope.
~~~~~ ~~ ~~~
Know how to go uphill. You may want to shift down to 0
a
e
e
a lower gear. The lower gears help cool your engine and
transaxle, and you can chb the hill better.
Stay in your own lane when driving on two-lane
roads
in hills or mountains. Don’t swing wide or cut
across the center of the road. Drive at speeds that let
you stay
in your own lane.
As you go over the top of a hill, be alert. There could be
something in your lane. like a stalled car or an accident.
You may see highway signs on mountains that warn of
special problems. Examples
are long grades, passing or
no-passing zones, a falling rocks area or winding
roads. Be
alert to these and take appropriate action.

Downloaded from www.Manualslib.com manuals search engine 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. 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.
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 transaxle fluid (don’t overfill),
engine oil, 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.

Downloaded from www.Manualslib.com manuals search engine If it isn’t, the coolant level should be indicated by a
CHECK COOLANT LEVEL message on the Driver
Information Center.
If it is, you may have a leak in the
radiator hoses, heater hoses, radiator, water
pump or
somewhere else in the cooling system.
A CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them. If
you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could
lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage if you keep running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
If there seems to be no leak, with the engine on, 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.

If you haven’t found a problem yet, but the coolant level
isn’t at the proper level
(2.5 inches (6.4 cm) below the
base
of the fill neck), add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL“ coolant at
the coolant surge tank, but be sure the cooling system,
including the coolant surge tank pressure cap,
is cool
before
you do it. (See “Engine Coolant” in the Index for
more information.)
* 0
Steam and scalding liquids from a hot cooling
system
can blow out and burn you badly. They are
under pressure, and if you turn the coolant surge
tank pressure cap
-- even a little -- they can come
out at high
speed. Never turn the cap when the
cooling system, including the coolant surge
tank
pressure cap, is hot. Wait for the cooling system
and coolant surge
tank pressure cap to cool if you
ever have to turn the pressure cap.
