Climate Control System
With this system, you can control the
ventilation and heating in your vehicle.
Your vehicle
also has the flow-through
ventilation system described later in this
section.
Lever Controls: The upper lever
changes the functions of your system.
The lower lever changes the temperature
of the air coming through the system.
Slide the upper control lever to
OFF to
turn
off the system.
3f : Sets the fan speed. To select the
force of air you want,'turn the knob.

VENT Use when outside temperatures
are mild and little heating or cooling is
needed. Air flow is through the
instrument panel outlets. Set the lower
lever to the temperature desired.
B/L (Bi-Level): Use on cool, but SUMY
days. This setting brings in the outside
air, but directs it in
two ways. The cool
air is directed to the upper portion of your
body through the instrument panel outlets,
but slightly warmer air is directed through
the heater ducts and defroster vents. At
times, this temperature difference may
be more apparent than others.
HTR (Heater): This setting brings
heated air through the heater ducts, and
some through the windshield defroster
vents.
If you have the optional engine block
heater and use it during cold weather,
0°F (-18°C) or lower, your heating
system will more quickly provide heat
because the engine coolant is already
warmed. See the
Index under Engine
Block Heater.
BLEND: This setting divides the air
flow equally between the heater ducts
and the windshield defroster vents.
DEF (Defrost): This setting directs
most air through the windshield
defroster vents, and some through the
heater ducts.
Defogging Windows
Slide the lower lever to HOT. To defog
the windows, set the upper lever to
DEF
and turn the fan control to HI.

VENT Use on pleasant days when little
heating or cooling is needed,
to direct
outside air into the vehicle.
In this

The coolant level should be at or above
FULL COLD. If it isn't, you may have
a leak
in the radiator hoses, heater
hoses, radiator, water pump
or
somewhere else in the cooling system.
II Heater and radiator hoses, and
L 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.
Engine damage from running
your
engine without coolant isn't
covered by your warranty.

When you decide it's safe to lift the
hood, here's what you'll see:
(A) Coolant surge tank with pressure cap
(B) Electric engine fan
An electric fan under the hood
L can start up even when the
engine
is not running and can injl
you. Keep hands, clothing and tows

If the coolant inside the coolant surge
tank is boiling, don't do anything else
until it cools down.

If there seems to be no leak, check to
see
if the electric engine fan is running.
If the engine is overheating, the fan

How to Add Coolant to the Coolant
Recovery Tank
(or the Coolant Surge
Tank):
If you haven’t found a problem yet, but
the coolant level isn’t at or above FULL
COLD,
add a 50/50 mixture of clean
water
(preferably distilled) and a proper
antifreeze at the coolant recovery
tank
(or coolant surge tank). If you have the
coolant surge tank, be sure
the cooling
system, including the coolant surge
tank
pressure cap, is cool before you do it.
See How To Add Coolant to the 2.2L L4
Engirze at the Radiator or How to Add
Coolant
to the 3.1L V4 Engine ut the
Coolant
Surge Tank later in this section.
A
Adding only plain water to
your cooling system can be
dangerous. Plain water, or some
other liquid like alcohol, can boil
before the proper coolant mix will.
Your vehicle’s coolant warning
system
is set for the proper cool an^
mix. With plain water or the
wrong
mix, your engine could get
too hot but you wouldn’t get
the
overheat warning, Your engine
could catch fire and you or others
could be burned. Use a 50150 mix
of clean water and a proper
antifreeze. In cold weather, water can freezt
and crack the engine, radiator,
heater core and other parts Ise
the recommended coolant.

FULL COLD.
5. Put the cap back on the coolant
recovery tank, but leave the radiator
pressure cap off. 6. Start the engine and let it run until
you can feel the upper radiator hose
getting hot. Watch
out for the engine
fan.
7. By this time, the coolant level inside
the radiator filler neck may be lower.
If the level is lower, add more of the
proper mix through
the filler neck
until the level reaches the base
of the
filler neck.

proper
mix, up to FULL COLD.
4. With the coolant surge tank pressure
cap
off, start the engine and let it run
until you can feel the upper radiator
hose getting hot. Watch out for
the
engine fan.
By this time, the coolant level inside the
coolant surge tank may be lower. If the
level
is lower, add more of the proper
mix to the coolant surge tank until the
level reaches
FULL COLD.
5. Then replace the pressure cap. Be
sure the arrows on the pressure cap
line up like this.
