I Climate Control System
Nith this system, you can control the
rentilation and heating in your vehicle.
four vehicle also has the flow-through
Jentilation system described later in this
rection.
Lever Controls: The upper lever
:hanges the functions
of your system.
rhe lower lever changes the temperature
If the air coming through the system.
Slide the upper control lever to
OFF to
:urn
off the system.
3f: Sets the fan speed. To select the
:orce 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 sunny
days. This setting brings in the outside
air, but directs it in two ways. Cool air
is directed to the upper portion of your
body through the instrument panel
outlets, and 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
coolant 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 Coolant Heater.
BLEND: This setting divides the air
flow equally between the heater duets
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
To defog the windows, slide the lower
lever to
HOT, set the upper lever to
DEF and turn the fan control to HI.

(OPTION)
The air conditioner and heater work
best if you keep your windows closed
while using them. 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: Selects the fan speed. To select the
force of air you want, turn the hob.
The fan is always running unless the
upper lever is moved to
OFF.
Air Conditioning
The upper lever has three air
conditioner settings. On very hot days,
open the windows long enough to let
hot inside air escape. This reduces the
amount of work your air conditioner's
compressor will have to do, which
should help fuel economy.
A/C (Air Conditioning): Press this
button
to enable the air conditioner
compressor. The indicator light will
glow when the button is pressed. Press
the button again to turn
off the air
conditioner compressor.
The air conditioner compressor
operates automatically (and the light
glows) when in the
MAX setting, or in
the
DEF (Defrost) setting when the outside temperature
is higher than
about 40°F (4.5"C). Below 40°F (4.5"C),
the light will glow in these settings, but
the compressor will not turn on.
MAX (Maximum): Use for maximum
cooling. This setting recirculates much
of the air inside your vehicle
so it
maximizes fuel economy and your air
conditioner's performance.
VENT: Use on pleasant days when little
heating or cooling is needed, to direct
outside air into the vehicle.
In this
setting, the air flow is through the
instrument panel outlets.
B/L (Bi-Level): Use on cool, but sunny
days. This setting brings in the outside
air, but directs it in two ways. Cool air
is directed to the upper portion of your
body through the instrument panel
outlets, and slightly warmer air is
directed to the lower portion of your
body through the heater ducts and
defroster vents. At times, this
temperature difference may be more
apparent than others.

Hill and Mountain Roads
Driving on steep hills or mountains is
different from driving in flat
or rolling
terrain.
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.
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.
Know how to go uphill. You may
want to shift down to a lower gear.
The lower gears help cool your engine
and transaxle, and you can climb 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.

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.

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

Howlo Add Coolant to the Coolant
Recovery Tank-2.2L f.4 Engine
If you haven’t found a problem yet, but
the coolant level isn’t at or above the
FULL COLD mark, add a 50/50
mixture of clean water (preferably
distilled) and a proper antifreeze at the
coolant recovery tank. (See
Coolant in
the
Index for more information about
the proper coolant mix.)

I NOTICE: I
In cold weather, water can freeze
and crack the engine, radiator,
heater core and other parts. Use the
recommended coolant. When
the coolant in the coolant
recovery tank is at or above the FULL
COLD mark, start your vehicle.
If the overheat warning continues,
there's one more thing you can try.
You
can add the proper coolant mix directly
to the radiator but be sure the cooling
system
is cool before you do it.

1. You can remove the radiator pressure
cap when the cooling system,
including the radiator pressure cap
and upper radiator hose, is no longer
hot. Turn the pressure cap slowly to
the left until
it first stops. (Don’t
press down while turning the
pressure cap.) If you hear a hiss, wait
for that to stop. A hiss means there is
still some pressure left.

2. Then keep turning the pressure cap,
but now push down as you turn it.
Remove the pressure cap. 3. Fill the radiator with the proper mix,
up to the base of the filler neck.
