Engine Coolant Heater (Option)
In very cold weather, 0
F (-18
C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm
-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't reach, use a
heavy
-duty three-prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug and store
the cord as it was before to keep it away from moving
engine parts. If you don't, it could be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.

If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature
Warning Light
This light tells you that your
engine coolant has
overheated or your radiator
cooling fan is not working.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn the engine off as soon as possible.
The ªProblems on the Roadº section in this manual
explains what to do. See ªEngine Overheatingº in
the Index.

2-73 Engine Coolant Temperature Gage
Your vehicle has a gage that
shows the engine coolant
temperature. If the gage
pointer moves into the red
area, your engine is too hot!
This reading means the same thing as the warning light.
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
The ªProblems on the Roadº section in this manual
explains what to do. See ªEngine Overheatingº in
the Index.
Low Coolant Warning Light
When this light comes on,
the cooling system is low
on coolant.
As a bulb check, it will come on for two to four seconds
and then go off when the ignition is in RUN. If the light
doesn't come on, have the vehicle serviced.
If the coolant level is low, the light will come back on
and a warning chime will sound. If this happens, see
ªEngine Coolantº in the Index for the proper cooling
system fill procedure.
After the coolant level is returned to its proper level, the
LOW COOLANT light will go off after 20 seconds or
remain off during the next ignition cycle.

Temperature Button
To adjust the comfort level you want maintained inside
the vehicle, push the TEMP button. If you want a
warmer comfort level, push the red arrow. If you want a
cooler comfort level, push the blue arrow. Your comfort
setting is shown in the display.
Fan Button
The speed of the blower fan is controlled automatically
if you have the system set for AUTO. Pressing the
FAN button will display and hold the current blower
fan setting.
If you want the blower fan to run at a lower speed, push
the bottom of the FAN button. The fan speed will
decrease with every push of the button until the lowest
speed is reached. If you want to increase the fan speed,
push the top of the FAN button. Notice the fan
indicators in the display.
Mode Controls
Press the AIR FLOW button to deliver air through the
floor, middle or windshield outlets. The system will stay
in the selected mode until the AUTO button is pushed.
Press the up arrow on the AIR FLOW button to cycle
through the available modes.Automatic Operation
Press the AUTO button when you want the system to
automatically adjust the interior temperature to your
preference. When the system is set for automatic
operation, air will come from the floor, middle or
windshield outlets depending on the temperature inside
the vehicle, the outside temperature and sun load. Fan
speed will vary as the system gets to and maintains the
comfort setting you have selected through the use of the
TEMP button.
To find your comfort setting, start with the system
in AUTO mode and the TEMP button adjusted to a
display of 75
F (24
C), give the vehicle about
20 minutes to stabilize, then readjust your comfort
setting if necessary. The display will show the comfort
setting for a few seconds and then it will display the
outside temperature. If you want to see your current
automatic fan speed, airflow direction and comfort
setting, press the AUTO button.
In cold weather, the system will delay turning on the
fan, to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. Pushing the FAN, AIR FLOW or
FRONT buttons will override this delay, turn off the
AUTO setting and change the fan speed.

Engine Overheating
You will find a coolant temperature gage and the
warning light about a hot engine on your instrument
panel. See ªEngine Coolant Temperature Gageº and
ªLow Coolant Warning Lightº in the Index.
If Steam Is Coming From Your Engine
CAUTION:
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 your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.

NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.
If No Steam Is Coming From Your Engine
If you get an engine 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:

Climb a long hill on a hot day.

Stop after high
-speed driving.

Idle for long periods in traffic.

Tow a trailer.If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. If your air conditioner is on, turn it off.
2. Turn on your heater to full hot at the highest fan
speed 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.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there's still no sign of steam, idle the engine for
three minutes while you're parked. If you still have
the warning, turn off the engine and get everyone out of
the vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.
