C. Air Delivery Mode Control
D. Air Conditioning
E. RecirculationTemperature Control:
Turn the
knob clockwise or counterclockwise

8-2 Climate Controls
If the knob is set on“0”(zero), some
outside air will still enter the vehicle
and will be directed according to the
position of the mode knob.
Air Delivery Mode Control:
Turn the knob clockwise or
counterclockwise to change the
current airflow mode.
Select from the following modes:
H(Vent): Air is directed to the
instrument panel outlets.
\(Bi-Level): Air is divided
between the instrument panel
outlets and floor and side window
outlets. Cooler air is directed to the
upper outlets and warmer air to the
floor outlets.
[(Floor): Air is directed to the
floor outlets. Recirculation cannot
be selected while in floor mode
because this could cause the
interior window to fog.
/(Floor/Defog): This mode
clears the windows of fog or
moisture. Air is directed to the floor,
windshield, and side window outlets.
When this mode is selected, the
system runs the air conditioning
compressor unless the outside
temperature is near freezing or
below. Recirculation is not available
in this mode.
0(Defrost): This mode clears
the windshield of fog or frost
more quickly. Air is directed to the
windshield and side window outlets.
When this mode is selected, the
system runs the air conditioning
compressor unless the outside
temperature is near, or below
freezing. Recirculation is not
available in this mode.
Do not drive the vehicle until all the
windows are clear.
#(Air Conditioning): Press to
turn the air conditioning system
on or off. An indicator light on the
button comes on to show that the air
conditioning is on.
The fan control must be on to use
the air conditioning.
There might be a slight change in
engine performance when the air
conditioning compressor shuts off
and turns on again. This is normal.
The system is designed to make
adjustments to help with fuel
economy while still maintaining
the selected temperature.
The air conditioning system
removes moisture from the air, so a
small amount of water might drip
under the vehicle while idling or
after turning off the engine. This is
normal.

10-22 Vehicle Care
6. Start the engine and let it rununtil the upper radiator hose can
be felt getting hot. Watch out for
the engine cooling fan.
7. By this time, the coolant level inside the radiator filler neck
might be lower. If the level is
lower, add more of the proper
DEX‐COOL coolant mixture
through the filler neck until the
level reaches the base of the
filler neck.
8. Replace the pressure cap. At any time during this procedure
if coolant begins to flow out
of the filler neck, reinstall the
pressure cap.
Notice:
If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
The vehicle has a coolant
temperature gauge displayed on
the instrument panel to warn if the
engine is overheating. See Engine
Coolant Temperature Gauge on
page 5‑9. If the engine is too hot,
the air conditioning might stop
working. This is normal and helps
cool the engine.
If the decision is made not to lift the
hood when the warning appears, but
instead get service help right away.
See Roadside Assistance Program
(U.S. and Canada) on page 13‑7
or Roadside Assistance Program
(Mexico) on page 13‑9. If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fan is running. If the engine
is overheating, the fan should be
running. If it is not, do not continue
to run the engine and have the
vehicle serviced.
The engine cooling fan speed
should increase when idle speed is
doubled by pushing the accelerator
pedal down. If it does not, the
vehicle needs service. Turn off the
engine.
Notice:
Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice: If the engine catches fire
because of being driven with no
coolant, the vehicle can be badly
damaged. The costly repairs
would not be covered by the
vehicle warranty.

Vehicle Care 10-23
If Steam is Coming from the
Engine Compartment
{WARNING
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam is Coming from
the Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
.Tows a trailer. See“Driving on
Grades” underTrailer Towing on
page 9‑57.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest
fan speed. Open the windows as
necessary. 3. In heavy traffic, let the engine
idle in N (Neutral) while stopped.
If it is safe to do so, pull off
the road, shift to P (Park)
or N (Neutral) and let the
engine idle.
If the temperature overheat gauge
is no longer in the overheat zone
or an overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
back on, continue to drive normally.
If the warning continues, pull
over, stop, and park the vehicle
right away.
If there is no sign of steam, idle
the engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down.
