2008 DODGE RAM 2500 POWER WAGON 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.

7. Return to the vehicle and press the programmed
HomeLinktbutton twice (holding the button for 2 sec-
onds each time). If the device is plugged in and activates,
programming is complete.
If the device does not activate, press the button a third
time (for 2 seconds) to complete the training.
If you are have any problems, or require assistance,
please call toll-free 1±800±355±3515 or, on the Internet at
www.HomeLink.com for information or assistance.
To program the remaining two HomeLinktbuttons,
repeat each step for each remaining button. DO NOT
erase the channels.
Gate Operator/Canadian Programming
Canadian radio-frequency laws require transmitter sig-
nals to ªtime-outº (or quit) after several seconds of
transmission ± which may not be long enough for
HomeLinktto pick up the signal during programming.Similar to this Canadian law, some U.S. gate operators are
designed to ªtime-outº in the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage
door or gate motor.
If you are having difficulties programming a garage door
opener or a gate operator, replace ªProgramming
HomeLinkº Step 3 with the following:
3. Continue to press and hold the HomeLinktbutton
while you press and release - every two seconds
(ªcycleº) your hand-held transmitter until
HomeLinkthas successfully accepted the frequency
signal. The indicator(s) will change from a slow to
rapid flash when trained.
If you unplugged the device for training, plug it back in
at this time.

control at any speed and press the snowflake
button located at the right of the control panel.
Conditioned air will be directed through theoutlets 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:

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 intoNEUTRAL 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.
