2008 DODGE RAM 3500 GAS 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
HomeLink,º 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 HomeLinkt
has successfully accepted the frequency signal. The
indicator(s) will change from a slow flash, to a rapid
flash when trained.
If you unplugged the device for training, plug it back in
at this time.

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.
Heater Only Ð If Equipped
The mode control (at the right of the
control panel) can be set in any of the
following positions:
Climate Control Location
Manual Heating Controls

Blower Control
The rotary knob on the left of the
control panel is the blower control.
Turn the knob clockwise to one of the
four positions to obtain the blower
speed you desire. To turn the blower
off, turn the knob to the far left posi-
tion.
Temperature Control
The rotary knob at the center of the
control panel controls the temperature
of the interior air. You can choose your
degree of comfort by rotating the
knob. The coldest temperature setting
is to the extreme left (blue region) and
the warmest setting is to the extreme
right (red region) of the rotation.
Air Conditioning and Heating Ð 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 snow-
flake button shows that the air conditioning is on. Press the
button a second time to turn the air conditioning off.

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.
Recirculation Pushbutton
Pushing the Recirculation button al-
lows interior air to recirculate continu-
ously in any position except defrost
and defrost/floor mode for rapid cool
down of the interior. See ªFast
Cooldownº later in this section.
Mode Control
The mode control allows you to
choose from several patterns of air
distribution.

Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it's rainy or humid. In most cases
turning on the air conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder it may be necessary to
direct air onto the windshield by using MIX Mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. Higher blower
speeds will reduce fogging. Interior fogging on the
windshield can be quickly removed by selecting the
defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarettesmoke, 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. For proper coolant type,
refer to ªRecommended Fluids and Genuine Partsº in
Section 7.
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.
