BI-LEVEL: This setting directs air into your
vehicle
in two ways. Cool air is directed to the upper
portion
of your body through the middle instrument
panel outlets while warmed air
is directed to the floor,
’’ HEATER/DEFROS’E This setting directs air to
the floor outlets and toward the windshield.
’/J HEATER: This setting directs warmed air
through the
floor outlets. Some warm air is diverted to
the windshield to minimize fogging.

DEFROST Press this button to quickly remove
fog
or frost from the windshield. This setting sends most
of the airflow to the windshield with only a small
amount to the
floor outlets.
@? DE-ICE (Option): Pressing this button helps to
remove ice or frost from the windshield. See “Heated
Windshield’’ later in this section.
DEFOG: Press this, button to divide the air between the
windshield and the heater outlets. This is useful when
fog appears on the windshield or side glass due
to
sudden rain or snowy conditions. This feature is not
available with the heated windshield option.
% FAN SPEEDS: Press the button with the fan
symbol until
AUTO is displayed on the screen. At this
setting, the
fan speed is automatically controlled. 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 engine coolant
to assure it is warm
enough
to provide heat. When the engine 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 at
a high speed, press the up arrow button until you
see HIGH 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, press the fan symbol button until
HIGH AUTO is shown on the display. If you want the
blower fan at a low speed, press the down arrow button
until
LOW is shown on the display. If you want the fan
speed
to run lower than the AUTO setting, press the
button until LOW AUTO is shown
on the display.
OFF: Press this button to turn the system off. Fresh air
will continue to flow through the vehicle, and the
system will try to maintain the previously
set
temperature. The outside temperature will show on the
display when the system is OW.

Engine Overheating
You will find an ENGINE COOLANT HOT-IDLE
ENGINE message
or a STOP ENGINE ENGINE
OVERHEATED message on the Driver Information
Center. There is also an engine temperature warning
light on the instrument panel. See “Engine Temperature
Warning Light”
in the Index.
Overheated Engine Protecaon Operating
Mode
Should a low coolant condition exist and the message
STOP ENGINE ENGINE OVERHEATED is displayed,
an overheat protection mode which alternates firing
groups
of four cylinders helps prevent engine damage.
This operating mode allows your vehicle
to be driven
to
a safe place in an emergency; you may drive up to
50 miles (80 km). Towing a trailer in the overheat
protection mode should be avoided.
NOTICE:
After driving in the Overheated Engine
Protection Operating Mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil may be
severely degraded. Change the
oil and reset the
oil life indicator. See “Engine Oil, When to
Change” in the Index.

Downloaded from www.Manualslib.com manuals search engine Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL rm (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain
in your
vehicle
for 5 years or 100,000 miles (1 66 000 km),
whichever occurs first.
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 Overheating” in
the Index.
A 50/50 mixture of water and the proper coolant for
your Cadillac will:
0 Give freezing protection aown to -34°F (-37°C).
0 Give boiling protection up to 265 “F (129 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If dicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant
will require change sooner -- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.
What to Use
Use a mixture of one-half clean water (preferably
distilled)
and one-half DEX-COOL (orange-colored,
silicate-free) antifreeze that meets
GM Specification
6277M, which won’t damage aluminum
parts. Use
GM Engine Coolant Supplement (sealer)
(GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need to add anything else.
A special procedure is required for adding sealer; see the
Cadillac service manual.
(To order a service manual, see
“Service and Owner Publications”
in the Index.)

Adding Coolant
If you need more coolant, add the proper mix at the
surge tank, but only when the engine is cool.
I A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.
c1
When replacing the pressure cap, make sure it is tight.
Surge Tank Pressure Cap
I NOTICE:
.-
The surge tank cap is a 15 psi (105 kPa) ’
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.
If the surge tank pressure cap needs to be replaced, a
General Motors 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, a General
Motors thermostat
is recommended.

The power steering fluid
reservoir
is located next to
the coolant surge tank on
the passenger’s side
of
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear
an unusual noise. A fluid loss in this system
could indicate
a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and look at the fluid level
on the dipstick.
The level should be
at the FULL COLD mark. If
necessary, add only enough fluid to bring the level up to
the mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid to use. See “Recommended Fluids and
Lubricants” in the Maintenance Schedule booklet.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use.
If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
