2012 DODGE GRAND CARAVAN ECO mode

Air Conditioning (A/C)
The Air Conditioning (A/C) button allows the operator
to manually activate or deactivate the air conditioning
system. When in A/C mode and the ATC is set to a cool
temperature, dehumidified air flows through the air
outlets. If Economy mode is desired, press the A/C
button to turn off the A/C mode in the ATC display and
deactivate the A/C system.
NOTE:
•If the system is in Mix, Floor or Defrost Mode, the A/C
can be turned off, but the A/C system shall remain
active to prevent fogging of the windows.
•If fog or mist appears on the windshield or side glass,
select Defrost mode and increase blower speed.
Recirculation Control
When outside air contains smoke, odors, or
high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the Recirculation control button. Re-
circulation mode should only be used temporarily. A LED
will illuminate on the Recirculation control button when
Recirculation mode is selected. Push the button a second
time to turn off the Recirculation mode LED and allow
outside air into the vehicle.
NOTE: In cold weather, use of the Recirculation mode
may lead to excessive window fogging. The Recirculation
mode is not allowed in Defrost mode to improve window
clearing operation. Recirculation will be disabled auto-
matically if this mode is selected.

Rear Automatic Temperature Control (ATC) — If
Equipped
The rear ATC system has floor air outlets at the rear of the
right side sliding door, and overhead outlets at each
outboard rear seating position. The system provides
heated air through the floor outlets or cool, dehumidified
air through the headliner outlets.
The rear system temperature control is on the front ATC
panel located on the instrument panel.
Pressing the Rear Temperature Lock button on the front
ATC panel, illuminates a lock symbol in the rear display.
The rear temperature and air source are controlled from
the front ATC panel.
Rear second row occupants can only adjust the rear ATC
control when the Rear Temperature Lock button is turned
off.The rear ATC system is located in the headliner, near the
center of the vehicle.

Headliner ModeAir 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.
Bi-Level Mode Air comes from both the headliner outlets and the
floor outlets.
NOTE: In many temperature positions, the Bi-Level
mode is designed to provide cooler air out of the head-
liner outlets and warmer air from the floor outlets.
Floor Mode Air comes from the floor outlets.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 solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” 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 “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended, because it
may cause window fogging.

Fuel Economy (ECON) Mode
The Fuel Economy (ECON) mode can improve the vehi-
cle’s overall fuel economy during normal driving condi-
tions. Press the “econ” switch in the center stack of the
instrument panel and a green light will indicate the
ECON mode is engaged.When the Fuel Economy (ECON) Mode is engaged, the
vehicle control systems will change the following:
•The transmission will upshift sooner and downshift
later.
•The transmission will skip select gears during shifts to
allow the engine to operate at lower speeds.
•The torque converter clutch will engage at lower
engine speeds and remain on longer.
•The engine idle speed will be lower.
•The overall driving performance will be more conser-
vative.
•Some ECON mode functions may be temporarily
inhibited based on temperature and other factors.

STARTING AND OPERATING 425

2. Shift the transmission into PARK.
3. Turn the engine OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE:Even if the transmission can be reset, we recom-
mend that you visit your 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.Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the shift
lever is in the DRIVE position. For example, if you shift
the transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gear normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Tapping the shift
lever to the left (-) will activate ERS mode, display the
current gear in the instrument cluster, and maintain that
gear as the top available gear. Once in ERS mode, tapping
the shift lever to the left (-) or right (+) will change the top
available gear.
432 STARTING AND OPERATING

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located in the
lower center area of the instrument panel.Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use the Hazard Warning flashers
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.
•On the highways — slow down.
•In city traffic — while stopped, place the transmission
in 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 (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
•You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control
to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat
from the engine cooling system.

WHAT TO DO IN EMERGENCIES 513

NOTE:To improve the vehicle’s traction when starting
off in deep snow, sand or gravel, it may be desirable to
switch the Electronic Stability Program (ESP) to “Partial
Off” mode. Refer to “Electronic Brake Control System” in
“Starting and Operating” for further information.
CAUTION!
•When “rocking” a stuck vehicle by moving be-
tween DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
•Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h) while in gear (no
transmission shifting occurring).
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause damage, or
even failure, of the axle and tires. A tire could
explode and injure someone. Do not spin your vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck and do not let anyone near
a spinning wheel, no matter what the speed.
SHIFT LEVER OVERRIDE
If a malfunction occurs and the shift lever cannot be
moved out of the PARK position, you can use the
following procedure to temporarily move the shift lever:
1. Firmly apply the parking brake.
