BATTERY VOLTAGE LOW - 6: This message
will appear when the electrical system is charging less
than 10 volts or if the battery has been drained. If this
message appears immediately after starting, it is
possible that the generator can still recharge the battery.
The battery should recharge while driving but may take a
few hours to do so. Consider using an auxiliary charger
(be sure to follow the manufacturer's instructions) to
boost the battery after returning home or to a final
destination. If this message appears while driving or
after starting your vehicle and stays on, have it checked
immediately to determine the cause of this problem.
To help the generator recharge the battery quickly, you
can reduce the load on the electrical system by turning off
the accessories. You can monitor battery voltage on the
DIC by pressing the INFO button. The normal range
is 11.5 to 15.5 volts.

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

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.

3-4
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.
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.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started. As the coolant warms
up, the blower fan speed will gradually increase and
air will flow from the heater outlets, with some airflow
to the windshield to prevent fogging under most
normal conditions.If you leave your vehicle, the system will remember the
control setting the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation, whereas, FRONT DEFROST will
change to automatic operation when the ignition is shut
off and then turned back on.
Manual Operation
You may manually adjust the air delivery mode or
fan speed.
AC: This setting directs airflow through the four
instrument panel outlets.
BI-LEVEL: This setting directs air into your
vehicle in two ways. Cool air is directed to the upper
portion of your body through the four instrument panel
outlets while warmed air is directed to the floor.
HEATER/DEFROST: This setting directs air to
the floor outlets and toward the windshield.
HEATER: This setting directs warmed air
through the floor outlets. Some warm air is diverted to
the windshield to minimize fogging.

3-5
DEFROST: Press this button to quickly remove
fog or frost from the windshield. This setting sends most
of the airflow to the windshield with only a small
amount to the floor outlets.
FAN SPEEDS: Press the AUTO. At this setting,
the fan speed is automatically controlled. If it is cold
outside, the blower may not run in the maximum high
fan speed right away. The system checks the
temperature of the engine coolant to assure that it is
warm enough to provide heat. When the engine coolant
is warm, the controller allows the fan to gradually
increase to a higher speed. This prevents cold air from
blowing into the passenger compartment.
OFF: Press the knob to turn the system off. Fresh air
will continue to flow through the vehicle, and the
system will try to maintain the previously set
temperature. The outside temperature will show on the
display when the system is OFF.AC: Press this button to turn the air conditioning on
and off. The system will cool and dehumidify the air
inside the vehicle. In the AUTO mode the air
conditioning compressor only operates when the system
determines it is needed. The display will show A/C OFF
when the air conditioning is off.
RECIRCULATION: Press this button to limit the
amount of fresh air entering your vehicle. This is helpful
when you are trying to cool the air quickly or limit odors
entering your vehicle. In the AUTO mode, the system
will use recirculation as necessary to cool the air.
Pressing the recirculation button will change the
operation to a manual mode and the air will recirculate
non
-stop. Press this button again to turn off the
recirculation feature.
If you notice the windows fogging, press the
recirculation button to exit the recirculation mode.

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.
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.
