2007 RAM CHASSIS CAB heating

Each heated seat switch has two settings (HI and LOW).
Press the switch once to obtain High heat level, then
press the switch again to obtain Low heat level. Pressing
the switch a third time will turn the heated seats OFF. If
you do not purposefully turn the switch OFF, the seat
heating level will automatically change to the next lower
level, or OFF. The High heat level operates for 30 minutes
(approximate), the Low heat level operates for 30 min-
utes (approximate). The seat heat will also turn OFF
when the ignition is turned OFF. Both of the indicators
ON identifies High heat level. The lower indicator On
only, identifies Low heat level. Flashing indicator lights
on the switch indicate that the Heated Seat System needs
servicing. WARNING!Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns even
at low temperatures, especially if used for long
periods of time.
Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This may
cause the seat heater to overheat. UNDERSTANDING THE FEATURES OF YOUR VEHICLE 119

NOTE: If you experience difficulty in playing a particu-
lar disc, it may be damaged, oversized, or have theft
protection encoding. Try a known good disc before
considering disc player service.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the operation of a cellular
phone in your vehicle can cause erratic or noisy perfor-
mance from your radio. This condition may be lessened
or eliminated by relocating the cellular phone antenna.
This condition is not harmful to the radio. If your radio
performance does not satisfactorily “clear” by the repo-
sitioning of the antenna, it is recommended that the radio
volume be turned down or off during cellular phone
operation. CLIMATE CONTROLS
The controls for the heating and ventilation system in this
vehicle consist of a series of rotary knobs. These comfort
controls can be set to obtain desired interior conditions.
Climate Control Location230 UNDERSTANDING YOUR INSTRUMENT PANEL

Heater Only — If Equipped
The mode control (at the right of the
control panel) can be set in any of the
following positions: NOTE: To improve your selection choices, the system
allows you to operate at intermediate positions between
the major modes. These intermediate positions are iden-
tified by the small dots.
Panel
Outside air flows through the outlets located in the
instrument panel.
Recirculation Modes (Panel or Bi-Level)
Select the recirculation modes when
the outside air contains smoke or
odors. This feature allows for recircu-
lation of interior air only. Air flows
through the panel outlets in this mode.
Air flows through the panel only or
through both the panel and floor vents
depending on the selected mode (panel vs bi-level).Manual Heating Controls UNDERSTANDING YOUR INSTRUMENT PANEL 231

Air Conditioning and Heating — If Equipped
Air Conditioning Operation
To turn on the Air Conditioning, set the fan
control at any speed and press the snowflake
button located at the right of the control panel.
Conditioned air will be directed through the outlets selected by the mode control. A light in the
snowflake button shows that the air conditioning is on.
Press the button a second time to turn the air condition-
ing off.
Slight changes in engine speed or power may be noticed
when the air conditioning compressor is on. This is a
normal occurrence as the compressor will cycle on and
off to maintain comfort and increase fuel economy.
The mode control (at the right of the
control panel) can be set in any of the
following positions:Air Conditioning And Heating UNDERSTANDING YOUR INSTRUMENT PANEL 233

Air Conditioning with Dual Zone Temperature
Control — If Equipped
With the Dual Zone Temperature Control System, each
front seat occupant can independently control the tem-
perature of air coming from the outlets on their side of
the vehicle. Air Conditioning and Heating Operation
To turn on the Air Conditioning, set the fan control at any
speed and press the snowflake button located on the
control panel. Conditioned air will be directed through
the outlets selected by the mode control. A light in the
snowflake button shows that the air conditioning is on.
Press the button a second time to turn the air condition-
ing off.
A/C Pushbutton
With the fan control in the ON posi-
tion, pushing the A/C button turns on
the air conditioning compressor. An
indicator light on the button shows
that the Air Conditioning compressor
is on. Conditioned air is now directed
through the mode outlets selected.
Pushing the button a second time turns the compressor
OFF.Dual Zone Control Head236 UNDERSTANDING YOUR INSTRUMENT PANEL

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Recommended
Fluids and Genuine Parts for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When stopped in heavy traffic, it may be necessary to shift into
NEUTRAL and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.
NOTE: On models equipped with Diesel engines, the
idle speed will automatically increase to 1000 rpm at
elevated coolant temperatures to improve engine cooling.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions. UNDERSTANDING YOUR INSTRUMENT PANEL 241
