Comfort Controls
This section tells you how to make your air system
work for you.
With the ECC system, you can control the heating,
cooling and ventilation in your vehicle. Your vehicle
also has a flow
-through ventilation system described
later in this section.
Climate Control Panel
Fan Button
The button with the fan symbol adjusts the fan speed.
Press the up arrow to increase fan speed and the down
arrow to decrease fan speed.Driver's Side Temperature Knob
The TEMP/AUTO knob adjusts the air temperature
coming through the system. Turn the TEMP/AUTO
knob clockwise to increase the temperature and
counterclockwise to decrease the temperature.
Press the TEMP/AUTO knob to put the system
in the automatic mode.
Passenger's Side Temperature Button
With this dual
-zone feature, the right front passenger
can control the temperature of air for his/her own zone.
The passenger can select a four degree warmer or cooler
temperature from the driver's setting. To turn the system
on, press the PASS/TEMP button. Press the up arrow
to increase the temperature and press the down arrow to
decrease the climate setting. Pressing the OFF button
will turn off the dual
-zone function.
Outside Temperature Display
The outside temperature is always displayed when your
vehicle is running. You can change it from Fahrenheit to
Celsius by pressing the SKIP INFO button (above the
radio) until ENGLISH/METRIC RESET displays.
Once displayed, press the NO INFO RESET button
to select.

The outside temperature sensor is located near the
front grille. The sensor can be affected by road or
engine heat during idling, slow driving or when the
engine is first started after a short trip. In order to
ensure proper automatic climate control operation,
the outside air temperature display may not update as
quickly as expected. This is to allow the air surrounding
the outside temperature sensor to be as close to the
actual outside conditions as possible. This is determined
by how much time has elapsed since the vehicle has
been turned off and by vehicle speed.
Mode Button
Press the MODE button to deliver air through the floor,
middle or windshield outlets. The system will stay in the
selected mode until the MODE button is pressed again.
Press the up or down arrow to cycle through the
available modes.
Automatic Operation
When the system is set for automatic operation,
sensors will control the air delivery mode. Air will
come from the floor, middle or windshield outlets.
The fan speed will vary as the system maintains the
selected temperature setting.Be careful not to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor is used by the automatic system
to regulate temperature.
To find your comfort zone, start with the 75
F (24
C)
setting and allow about 30 minutes for the system to
regulate. Turn the TEMP/AUTO knob to adjust the
temperature if necessary. If you choose 60
F (16
C),
the system will remain at that maximum cooling
setting and will not regulate fan speed. If you choose
the temperature of 90
F (32
C), the system will
remain at that maximum heating setting and will not
regulate fan speed. Choosing either maximum setting
will not cause the system to heat or cool any faster.
With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the
need for heat, the airflow will be directed out the floor
outlets. As the interior temperature approaches a desired
setting, the blower speed will decrease. To maintain
interior comfort, the airflow may move to the instrument
panel air outlets and floor outlets (bi
-level mode).
On bright sunny days in cold weather, the airflow may
come out of the air conditioning outlets (AC mode) to
maintain comfort and prevent stuffiness.

3-7 Heating
Press the MODE button to select heater. Adjust the
interior temperature to a comfortable level and if the fan
speed needs adjusting, press the up or down arrow.
Outside air will be brought in and sent through the floor,
air conditioning or bi
-level outlets (depending on the
condition). The heater works best if you keep your
windows closed while using it.
Defrosting
Use defrost to remove fog or ice from the windshield
quickly in extremely humid or cold conditions.
Press the MODE button. If you select DEFROST,
adjust the fan speed by pressing the fan button up or
down. If you select DEFROST from AUTO, the system
will control the fan speed. The temperature also needs to
be adjusted by turning the TEMP/AUTO knob.
Recirculation is not available in the defrost or
defog modes.
Rear Window Defogger
The lines you see on the
rear window warm the
glass. Press this button to
turn on the rear defogger.
With it, the rear window
and both outside rearview
mirrors are heated.
The system will automatically shut off after 10 minutes.
If further defogging is desired, press the button again.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid or the
integrated rear window antenna, and the repairs
wouldn't be covered by your warranty.

Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.

When you enter a vehicle in cold weather, adjust the
fan to the highest speed for a few moments before
driving off. This helps clear the intake outlets of
snow and moisture, and reduces the chance of
fogging the inside of the windows.

Keep the air path under the front seats clear of
objects. This helps circulate air throughout
your vehicle.HVAC Steering Wheel Controls
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. SeeªAudio
Steering Wheel Controlsº
in the Index.
FAN SPEED: Press the up arrow lever to
increase the fan speed and the down arrow lever to
decrease fan speed.
TEMP: Press the up arrow lever to increase
the temperature and the down arrow lever to
decrease temperature.

4-36 Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if
possible, have someone guide you.
Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you're turning with a trailer, make wider turns than
normal. Do this so your trailer won't strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a different
turn signal flasher and/or extra wiring. Check with your
dealer. The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you're about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind you
are seeing your signal when they are not. It's important
to check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don't shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around 45 mph (70 km/h) or less to reduce the
possibility of engine and transaxle overheating.

4-37 Parking on Hills
CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People can
be injured, and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply your regular brakes, but do not shift
into PARK (P).
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
PARK (P) firmly and apply your parking brake.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:

Start your engine;

Shift into a gear; and

Be sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule booklet for
more on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don't overfill),
engine oil, drive belt, cooling system and brake system.
If you're trailering, it's a good idea to review this
information before you start your trip.
Check periodically to see that all hitch nuts and
bolts are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See ªEngine Overheatingº
in the Index.

Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº in the Index.
Engine Overheating
You will find an ENGINE COOLANT HOT, IDLE
ENGINE message or an ENGINE OVERHEATED,
STOP ENGINE message on the Driver Information
Center (DIC). You will also hear a chime. There is also
an engine temperature warning light and/or gage on the
instrument panel. See ªEngine Coolant Temperature
Warning Lightº or ªEngine Coolant Temperature Gageº
in the Index.
Overheated Engine Protection
Operating Mode
Should an overheated engine condition exist and the
message ENGINE OVERHEATED, STOP ENGINE is
displayed, an overheat protection mode which alternates
firing groups of cylinders helps prevent engine damage.
In this mode, you will notice a loss in power and engine
performance. 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 will be severely degraded.
Repair the cause of coolant loss, change the oil
and reset the oil life indicator. See ªEngine Oilº
in the Index.

5-13
A low coolant level should be indicated by a CHECK
COOLANT LEVEL message on the Driver Information
Center. If it is, you may have a leak in the radiator
hoses, heater hoses, radiator, water pump or somewhere
else in the cooling system.
CAUTION:
Heater and radiator hoses, and 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.
NOTICE:
Engine damage from running your engine
without coolant isn't covered by your warranty.
See ªOverheated Engine Protection Operating
Modeº in the Index.
NOTICE:
When adding coolant, it is important that you
use only DEX
-COOL
(silicate-free) coolant.
If coolant other than DEX-COOL 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. Damage caused by the
use of coolant other than DEX
-COOL
is not
covered by your new vehicle warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fans are running. If the
engine is overheating, both fans should be running. If
they aren't, your vehicle needs service.

6-22 How to Reset Transaxle Fluid
Change Indicator
Your vehicle is equipped with a transaxle fluid change
indicator. A CHANGE TRANS FLUID message will
display on the Driver Information Center (DIC) when
the powertrain computer determines that the transaxle
fluid needs to be changed or at each 100,000 miles
(160 000 km) interval, whichever occurs first. See your
Maintenance Schedule booklet for more information.
When this message appears, change the transaxle fluid
and reset the transaxle fluid life indicator as follows:
1. Turn the ignition on but do not start the engine.
2. Press and hold the OFF and rear defog buttons on the
climate control system at the same time until the
TRANS FLUID RESET message appears on
the DIC.
Engine Coolant
The cooling system in your vehicle is filled with
DEX
-COOL
engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX
-COOL
extended life coolant.
The following explains your cooling system and how to add
coolant when it is low. If you have a problem with engine
overheating, see ªEngine Overheatingº in the Index.
A 50/50 mixture of clean, drinkable water and
DEX
-COOL
coolant will:

Give freezing protection down to
-34F (-37C).

Give boiling protection up to 265F (129C).

Protect against rust and corrosion.

Help keep the proper engine temperature.

Let the warning lights and gages work as they should.
