Comfort Controls
This section tells you how to make your air system work
for you.
With this 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 knob adjusts the air temperature coming through the
system. Turn the knob clockwise to increase the
temperature and counterclockwise to decrease the
temperature. Press the knob to turn the system off.
Passenger's Side Temperature Button
With this feature, the right front passenger can control
the temperature of air for his/her own zone. The
passenger can select a 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 PASS/OFF button will turn off the
dual
-zone function.
Rear Passenger Climate Control
With this feature, the rear passenger (s) can control the
temperature of the air for the rear compartment.
To adjust the direction of the air flow, press the MODE
button, to adjust the blower speed, press the fan symbol
button and to adjust the temperature, press the TEMP
button. The driver can also override the system and select
a PASS OFF button to turn off the rear climate controls.
See ªRear Climate Controlº later in this section.

3-3
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 ENG/MET (English/metric)
button on the left side of the instrument panel cluster.
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 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.

3-6 Electronic Solar Sensor
The sensor monitors the sun's solar radiation and is
located on top of the instrument panel near the
windshield. The ECC panel uses this information to
automatically make the necessary temperature and
airflow adjustments to maintain your comfort.
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 AUTO button or the TEMP knob to turn the
system on. 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 keep the
desired temperature.
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.

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 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.
Climate Control Personalization
(If Equipped)
With this feature, your vehicle will recall the latest
climate control settings as adjusted the last time your
vehicle was operated. This feature allows two different
drivers to store and recall their own climate control
settings. The settings recalled by the climate control
system are determined by which remote keyless entry
transmitter (ª1º or ª2º) was used to enter the vehicle.
The number on the back of the remote keyless entry
transmitter corresponds to driver 1 or to driver 2. After
the unlock button is pressed on the remote keyless entry
transmitter or the ignition key is placed in the ignition
(the ignition must be turned to OFF), the climate control
settings will automatically adjust to where they were last
set. The settings can also be changed by briefly pressing
the memory seat buttons 1 or 2 located on the
driver's door.

4-41 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.
For some grade conditions, it may be better to drive in
THIRD (3) to lessen transaxle shifting. You may wish to
drive in THIRD (3) instead of DRIVE (D) while towing
a trailer.
On a long uphill grade, reduce your speed to around
45 mph (70 km/h) or less to reduce the possibility of
engine and transaxle overheating.

4-42 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 brakes.
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.

NOTICE:
Use the proper towing equipment to avoid
damage to the bumper, fascia or fog lamp areas
of the vehicle.
With current trends in automotive styles and design, it is
essential that the correct towing equipment is used to
tow a vehicle. Your vehicle can be towed with wheel lift
or car carrier equipment.
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.

5-14
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.
How to Add Coolant to the Coolant
Surge Tank
If you haven't found a problem yet, but the coolant level
isn't at the proper level (2.5 inches (6.4 cm) below the
base of the fill neck), add a 50/50 mixture of clean,
drinkable water and DEX
-COOL
coolant at the
coolant surge tank, but be sure the cooling system,
including the coolant surge tank pressure cap, is cool
before you do it. (See ªEngine Coolantº in the Index for
more information.)
CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They are
under pressure, and if you turn the coolant surge
tank pressure cap
-- even a little -- they can come
CAUTION: (Continued)
CAUTION: (Continued)
out at high speed. Never turn the cap when the
cooling system, including the coolant surge tank
pressure cap, is hot. Wait for the cooling system
and coolant surge tank pressure cap to cool if you
ever have to turn the pressure cap.
