2008 DODGE GRAND CARAVAN instrument panel

Operation of the rear system is quite simple.
1. Press the REAR LOCK button on the front ATC control
unit. This turns off the REAR LOCK icon in the rear
temperature knob.
2. Rotate the Rear Blower, Rear Temperature and the
Rear Mode Control knobs to suit your comfort needs.
3. ATC is selected by adjusting the rear blower knob
counterclockwise to AUTO.
Once the desired temperature is displayed, the ATC
System will automatically achieve and maintain that
comfort level. When the system is set up for your comfort
level, it is not necessary to change the settings. You will
experience the greatest efficiency by simply allowing the
system to function automatically.NOTE:
²It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode and fan speed to provide
comfort as quickly as possible.
²The temperature can be displayed in U.S. or Metric by
selecting the US/M customer programmable feature.

CAUTION!
Interior air enters the Rear Automatic Temperature
Control System through an intake grille located in
the passenger side trim panel behind the third seat.
The heater outlets are located in the passenger side
trim panel just behind the sliding door. Do not block
or place objects directly in front of the inlet grille or
heater outlets. The electrical system could overload
causing damage to the blower motor.
Rear Temperature Control
To change the temperature in the rear of the vehicle,
rotate the temperature knob counterclockwise to lower
the temperature and clockwise to increase the tempera-
ture. The REAR temperature settings are displayed in the
front ATC control.When rear controls are locked by the front system, the
LOCK symbol on the temperature knob is illuminated
and any rear overhead adjustments are ignored.
Rear Mode Control
AUTO Mode
The rear system automatically maintains the correct
mode and comfort level desired by the rear seat occu-
pants.
FLOOR Mode
Air comes from the floor outlets.
BI-LEVEL Mode
Air comes from both the headliner outlets and the
floor outlets.

HEADLINER Mode
Air comes from the outlets in the headliner. Each of
these outlets can be individually adjusted to direct
the flow of air. Moving the air vanes of the outlets to one
side will shut off the airflow.
SUMMER OPERATION
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to section 7, ªMaintenance Proceduresº, of this manual
for proper coolant selection.
WINTER OPERATION
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to section 7,ªMaintenance Proceduresº, of this manual for proper
coolant selection. Use of the air RECIRCULATION mode
during winter months is not recommended because it
may cause window fogging.
VACATION/STORAGE
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
WINDOW FOGGING
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, select DE-
FROST or MIX mode and increase the front blower
speed. Do not use the RECIRCULATION mode without
A/C for long periods, as fogging may occur.

OUTSIDE AIR INTAKE
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow and if they
enter the plenum they could plug the water drains. In
winter months make sure the air intake is clear of ice,
slush and snow.

A/C AIR FILTER Ð IF EQUIPPED
On vehicles equipped with Automatic Temperature Con-
trol (ATC), the climate control system filters out dust and
pollen from the air. Refer to Section 7 ªAir Conditioningº
for filter replacement instructions.
ELECTRIC REAR WINDOW DEFROSTER Ð IF
EQUIPPED
Press this button (located on your front climate
control) to turn on the rear window defroster and
the optional heated mirrors. A light will show that the
defroster is on. The defroster automatically turns off after
about ten minutes of operation, as long as the ignition
switch is in the ON position.
After the initial time interval has expired, if the rear
window defogger switch is pressed to the on position
again (during the same ignition cycle), the system will
automatically turn off after about five minutes.NOTE:You may turn off the heated mirror feature at
anytime by pressing the rear window defogger switch a
second time.
CAUTION!
To avoid damaging the electrical conductors of the
rear window defroster, do not use scrapers, sharp
instruments, or abrasive window cleaners on the
interior surface of the window.
Labels can be peeled off after soaking with warm
water.

Automatic Transmission Ignition Interlock System
For electrical system malfunctions, there is an override
for the interlock system. In order to override this system,
remove the cover located to the top right of the gear
selector lever in the instrument panel. The override can
be activated by pressing the white-colored tab, which can
be accessed through the hole in the instrument panel.
While the override is pressed, the gear selector lever can
be moved out of the PARK position without pressing the
brake pedal. After operation, return the cover to its
original position.
This system prevents the key from being removed unless
the gear selector lever is in PARK. It also prevents shifting
the gear selector lever out of PARK unless the key is in
the LOCK/OFF or ON positions.NOTE:If a malfunction occurs, the system will trap the
key in the ignition cylinder to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key cannot be removed until you obtain
service.
Four-Speed or Six-Speed Automatic
Transmission
The electronically controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
The transmission has only PRND shift positions. Down-
shifts are carried out by an Electronic Range Select (ERS)
by moving the leverÐ/+while in the DRIVE position,

NOTE:Even if the transmission can be reset, it is
recommended that you visit an authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.
PARKING BRAKE
When the parking brake is applied with the ignition
switch ON, the brake light in the instrument cluster will

Hazard Warning Flashers will continue to operate even
though the ignition switch is OFF.NOTE:With extended use, the Hazard Warning Flash-
ers may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
²On the highways Ð Slow down.
²In city traffic Ð While stopped, shift the transmission
gear selector lever into NEUTRAL, but do not increase
engine idle speed.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
