DODGE GRAND CARAVAN 2005 Owners Manual

The center knob on the front climate control unit has five
positions, “ REAR ” , “ OFF ” , and a range of blower speeds.
Only when the primary control for the rear blower is in
the “ REAR ” position do the second seat occupants have
control of the rear blower speed.
The rear blower control, located in the headliner near the
center of the vehicle has an OFF position and 3 blower
speed positions. This allows the second seat occupants to
control the volume of air circulated in the rear of the
vehicle. CAUTION!Interior air enters the Manual Rear Zone Climate
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. UNDERSTANDING YOUR INSTRUMENT PANEL 271

Rear Temperature And Mode Control
When the center knob on the front climate control unit is
set to the “ REAR ” position, the second seat occupants
have control of the rear temperature and modes as
follows:
• The rear temperature knob controls both the rear
temperature and mode. When the temperature knob is
in the cold position, cold air will be delivered from the
headliner outlets. As the rear temperature knob is
turned towards hot, the air will get warmer, and the
air will be delivered from both the headliner and floor
outlets. When the rear temperature knob reaches the
full hot position, all of the air will be delivered from
the floor outlets.
• When the center knob on the front climate control unit
is set to any position other than “ REAR ” , the rear temperature selection follows the setting of the driv-
er ’ s temperature control on the front climate control
unit. The rear mode selection follows the setting of the
front mode control.
Rear Economy Mode
If rear economy mode is desired, set the center knob on
the front control unit to the “ REAR ” position. Turn the
A/C button OFF and select any mode except “ MIX ” or
“ DEFROST ” .
The rear temperature knob and the rear blower speed can
be adjusted as desired by the second seat occupants.
Infrared Three-Zone Automatic Temperature
Control — If Equipped
The Infrared Three-Zone Automatic Temperature Control
System automatically maintains the interior comfort level
desired by the driver and all passengers. This is accom-
plished by using two infrared sensors, located in the
center of the instrument panel. The two infrared sensors272 UNDERSTANDING YOUR INSTRUMENT PANEL

independently measure the surface temperature of the
driver and passenger. Based on the sensor input, the
system automatically adjusts the air temperature, the air
flow volume, and amount of outside air recirculation.
This maintains a comfortable temperature even under
changing conditions.
Operation of the system is quite simple. Begin by press-
ing the auto rocker switch to the “ HI ” or “ LO ” position,
the word “ AUTO ” will illuminate in the front ATC display along with “ HI ” or “ LO ” . The system will then
automatically regulate the amount of air flow. Next, dial
in the temperature you would like the system to maintain
by pressing the driver ’ s or passenger ’ s temperature con-
trol button. The rear temperature can only be adjusted
from the front when the “ REAR SYSTEM ” knob on the
front ATC unit is in the “ AUTO ” position. Once the
desired temperature is displayed, the system will achieve
and maintain that comfort level automatically. 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:
• It 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.Three-Zone Automatic Temperature Control UNDERSTANDING YOUR INSTRUMENT PANEL 273

mable Features ” in Section 3 of this manual.
To provide you with maximum comfort in the automatic
mode, during cold start-ups the blower fan will remain
off and “ DELAY ” will appear in the front ATC display
until the engine warms up. Also, an estimate of the time
remaining until the “ DELAY ” is over will appear peri-
odically in the display. However, the fan will engage
immediately if the defrost mode is selected or by rotating
the blower control to any fixed blower speed.
This feature may be disabled using the following proce-
dure:
• Press and hold the Heated Rear Window and Auto LO
buttons for 5 seconds. • The “ DELAY ” symbol will flash to indicate that the
