Comfort Controls
This section tells you how to make your air system
work for you.
With the climate control 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 Switch
!~
(Fan): The switch 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 Switch
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 temperature that is up to
four degrees warmer or cooler than the driver's setting.
To turn the system on, press the PASS/TEMP switch.
Press the up arrow to increase the temperature and press
the down arrow to decrease it. 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 with the Driver Information Center (DIC).
Pressing the SKIP INFO button (above the radio) until
ENGLISH/METRIC RESET is displayed. Then press
the NO INFO RESET button to select.

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 of the
floor outlets. As the interior temperature approaches a
desired setting, the fan 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.
If your vehicle is sitting out on a hot day and you
have it set on AUTO, the air will first flow out the
floor air outlets for a few seconds. That is normal.
This is to expel hot air from the air outlets. As the
air is cooled, the airflow will move through the air
conditioning outlets. If you start your vehicle with the
fan setting on HI, it will skip the air conditioning purge.

3-7 Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
Press the AC button or the TEMP/AUTO knob to turn
the system on and then select the proper mode to direct
airflow. The system will cool and dehumidify the air
inside the vehicle. Also while in the AUTO mode, the
system will use recirculation as necessary to cool the air.
You may also need to adjust the interior temperature and
the fan speed as needed.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle's engine speed
and power. This is normal because the system is
designed to cycle the compressor on and off to
maintain the desired temperature.
Heating
Press the MODE switch to select the heater mode.
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.
Defogging and Defrosting
Use defrost to remove fog or ice from the windshield
quickly in extremely humid or cold conditions.
Press the MODE switch. If you select defrost mode,
adjust the fan speed by pressing the fan switch up or
down. If you select defrost mode 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.

3-10 HVAC Steering Wheel Controls
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. See ªAudio
Steering Wheel Controlsº
in the Index.
(Fan): 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.
Climate Control Personalization (If Equipped)
This feature allows both drivers (driver 1 or 2 depending
on the number on the back of your remote keyless entry
transmitter) to personalize their own climate control
settings. For more information, see ªMemory and
Personalization Featuresº in the Index.
Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off.
See ªRetained Accessory Powerº in the Index.
Setting the Clock
Press and hold HR or MN until the time display begins
to change. Release the button as you get close to the
correct time. The time may be set anytime the clock is
displayed. There is a two
-second delay before the clock
goes into time
-set mode.

4-39 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.
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 behind 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.

4-40 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

make 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 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.
Each of these is covered in this manual, and the Index
will help you find them quickly. 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.
