For correct operation of the low oil sensing system, the vehicle should be
on a level surface.
A false LOW OIL LEVEL message may appear if the
vehicle is parked
on grades. The oil 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 LOW
OIL LEVEL message appears, and your vehicle has been parked on level
ground with the engine
off for at least 30 minutes, your oil level should be -
checked by observing the oil dipstick. Prior to checking your oil level be
sure your engine has been
off for five minutes and your vehicle is on a
level surface. Then check
your dipstick and add oil if necessary. See
“Engine Oil”
in the Index.
CHECK WASHER FLUID - 25
This message will appear for a few seconds indicating that you need
washer solvent.
CHANGE OIL SOON - 40
This message will appear when you have used 90% of the engine oil’s
expected life, based on your driving patterns.
CHANGE ENGINE OIL - 82
This means that the life of your engine oil has expired and it should be
changed
within 200 miles. See “Engine Oil” and “Filter
Recommendations” in your maintenance schedule booklet. After an
oil
change the Oil Life Index must be reset. See “Oil Life Indicator” in the
Index on how to reset it.
CRUISE ENGAGED - 43
This message will appear for a few seconds when you select a speed at
which to cruise.

Downloaded from www.Manualslib.com manuals search engine AUTO
With this setting, the air conditioning compressor cycles when needed to
cool the air and it's all automatic. In cold weather when the system senses
the need
for heat, the airflow will be directed out the floor ducts. As the r--T
interior temperature approaches the desired setting, the blower speed will
decrease and the airflow could be directed through the defroster and floor
ducts.
To maintain interior comfort, the airflow may move to the
instrument panel air outlets and floor ducts (Bi-Level).
On bright sunny
days in cold weather, the airflow may come out
of the A/C outlets
(Bi-Level mode) to maintain comfort and prevent stuffiness.
Electronic Climate Control Features
A/C PURGE
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 ducts for a few seconds. That is
normal. This is to expel hot air in the air ducts.
As the air is cooled, the
flow will move through the
A/C outlets. If you start your vehicle with the
fan setting on HI it will skip the
A/C Purge.
COLD WEATHER PURGE
-.
On cold days when your system is first turned on, in either the AUTO or
ECON setting, and the fan setting is not on HI, a small amount of air will
flow through the defroster duct while the system is waiting for the engine
coolant to warm up enough to provide heat. This prevents your breath
from fogging your windshield. As the coolant warms up, the blower fan
speed will gradually increase and air will flow from the heater outlets, .. 3
with some airflow to the windshield to prevent fogging under most normal
conditions.
MANUALLY RECIRCULATE INSIDE AIR
There may be times when you want less air from the outside. To
recirculate the air from the inside, in the AUTO setting, just set the
temperature to
60" F (16O C) and adjust your fan speed.

Press this button to divide the air between the windshield and the heater
ducts. This is useful when fog appears on the windshield or side glass due
to sudden rain or snowy conditions.
FAN SPEEDS
Press the fan symbol button
until AUTO is displayed on
At this setting, the fan speed is controlled automatically.
If it is cold outside, the blower may not run in the maximum high fan
speed right away. The system checks the temperature of the coolant to
assure it is warm enough to provide heat. When the coolant is warm, the
controller allows the fan to gradually increase to a higher speed. This
prevents cold air from blowing into the passenger compartment.
If you want the blower fan to run only at a fixed high speed, press the
(upper) button until you see
HI on the display.
If you want the fan speed to be automatic, but you like the fan speed to be
higher than the AUTO setting, just press the fan symbol button until
HI/AUTO is shown on the display.
If
you want the blower to run only at a fixed low speed, press the (lower)
button until
LO is shown on the display.
If you want the fan speed to run lower than the AUTO setting, press the
button until AUTO
LO is shown on the display.

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.
Engine Coding When Trailering
Your cooling system may temporarily overheat during severe operating
conditions such as:
Climbing grades steeper than 4% at ambient 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.
If the ENGINE HOT-A/C COMPRESSOR OFF message appears on the
Driver Information Center, do
not be alarmed. This is a normal function
designed to reduce the load on the engine and cooling system. You can
continue to drive your vehicle.
If the ENGINE COOLANT HOT-IDLE ENGINE message appears on
the Driver Information Center, pull
off to the side of the road as soon as
it is safe to do
so. When the vehicle is at a complete stop, shift the
transaxle selector to PARK
(P) and allow the engine to idle. Do not turn
off the engine or increase engine speed above a normal idle. After several
minutes, resume driving at a reduced speed. Return
to normal driving
after
10 minutes if the ENGINE COOLANT HOT-IDLE ENGINE
message is not displayed.

lj?Nu Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get
a little too hot when you:
-
0 Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign
of steam, try this for a minute
or
so:
1. Turn off your air conditioner.
2. Dial temperature control to the highest heat setting and open the
window, as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N); otherwise, shift to
the highest gear while driving
-- AUTOMATIC OVERDRIVE (@) or
THIRD
(3). -
If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower for about
10 minutes. If the warning doesn’t come back on,
you can drive normally.
L
c4
If the warning continues, pull over, stop, and park your vehicle right away.
If there’s still no sign of steam, you can idle the engine for two or three
minutes while you’re parked, to see if the warning stops. But then, if you
still have the warning,
turn ofithe engine and get everyone out of the vehicle
until it cools down. Also see “Overheated Engine Protection Operating
Mode” listed previously
in this section.
You may decide not to lift the hood but to get service help right away.

The following explains your cooling system and how to add coolant when
it
is low. If you have a problem with engine overheating, see “Engine
The proper coolant
for your Cadillac will:
Give freezing protection down to -34OF (-37OC).
m_ Overheating” in the Index.
Give boiling protection up to 262°F (128°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should.
What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze that meets
“GM Specification 1825M,” which won’t damage
aluminum parts. You can also use a recycled coolant conforming to GM
Specification 1825M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant flush and
refill. If you use this mixture,
you don’t need to add anything else.

NOTICE:
Your surge tank cap is a 15 psi (105 Wa) pressure-type cap and
must be tightly installed to prevent coolant loss and possible
engine damage from overheating. Be sure the arrows on the cap
line up with the overflow tube on the radiator filler neck.
If your surge tank pressure cap needs to be replaced an AC' cap is
recommended.
THERMOSTAT
Engine coolant temperature is controlled by a thermostat in the engine
coolant system. The thermostat stops the
flow of coolant through the
radiator until the coolant reaches a preset temperature.
If your thermostat needs to be replaced an AC@ thermostat is
recommended.
