2012 RAM CHASSIS CAB air condition

the repair technician should leave the odometer reading
the same as it was before the repair or service. If s/he
cannot do so, then the odometer must be set at zero, and
a sticker must be placed in the door jamb stating what the
mileage was before the repair or service. It is a good idea
for you to make a record of the odometer reading before
the repair/service, so that you can be sure that it is
properly reset, or that the door jamb sticker is accurate if
the odometer must be reset at zero.
The two trip odometers show individual trip mileage. To
switch from odometer to trip odometers, press and
release the TRIP ODOMETER button.
To reset a trip odometer, display the desired trip odom-
eter to be reset then push and hold the button for
approximately two seconds until the display resets. Vehicle Odometer Messages

gASCAP ...................... GasCap Loose
HOTOIL ................... Engine Oil too Hot
LoCOOL ................... Low Engine Coolant
LoW tirE .................... TirePr essure Low
NOTE: There is also an engine hour function. This
indicates the total number of hours the engine has been
running. To display the engine hours on the base cluster,
perform the following: Place the ignition in the ON/

WARNING!A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could result
in death or serious injury to the driver, occupants or
others.
24. Air Bag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, have the system inspected at an authorized
dealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information. 25. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.
26. Anti-Lock Brake (ABS) Light
This light monitors the Anti-lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the anti-lock portion of the brake system is
not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of anti-lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.200 UNDERSTANDING YOUR INSTRUMENT PANEL

CD/DVD DISC MAINTENANCE
To keep a CD/DVD in good condition, take the following
precautions:
1. Handle the disc by its edge; avoid touching the
surface.
2. If the disc is stained, clean the surface with a soft cloth,
wiping from center to edge.
3. Do not apply paper or tape to the disc; avoid scratch-
ing the disc.
4. Do not use solvents such as benzene, thinner, cleaners,
or anti-static sprays.
5. Store the disc in its case after playing.
6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become
too high. NOTE: If you experience difficulty in playing a particu-
lar disc, it may be damaged (i.e., scratched, reflective
coating removed, a hair, moisture or dew on the disc)
oversized, or have protection encoding. Try a known
good disc before considering disc player service.
RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile phone being on in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the mobile phone antenna. This condition is
not harmful to the radio. If your radio performance does
not satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during mobile phone operation when
not using Uconnect™ (if equipped).

CLIMATE CONTROLS
The Climate Control System allows you to regulate the
temperature, amount, and direction of air circulating
throughout the vehicle. The controls are located on the
instrument panel below the radio.
NOTE: During snowplow usage on vehicles equipped
with outside temperature display, the display may show
higher temperatures than the outside ambient tempera-
ture. The higher displayed temperature is due to blocked
or reduced airflow to the underhood ambient tempera-
ture sensor caused by the snowplow. In addition, on
vehicles equipped with Automatic Temperature Control
(ATC), it is suggested that the interior cabin temperature
be manually controlled should the system not perform as
desired while in automatic mode. Both the outside tem-
perature display and ATC operation will return to nor-
mal when the snowplow is removed. Manual Heating And Air Conditioning System
The controls for the manual heating and air conditioning
system in this vehicle consist of a series of outer rotary
dials and inner push knobs. These comfort controls can
be set to obtain desired interior conditions.
1 – Front Blower 4 – DEFROST Mode
2 – Temperature Control 5 – Air Conditioning (A/C)
3 – MODE Control 6 – RECIRCULATION Control256 UNDERSTANDING YOUR INSTRUMENT PANEL

Front Blower Control
There are four blower speeds. Use this
control to regulate the amount of air
forced through the system in any
mode you select. The blower speed
increases as you move the control
clockwise from the OFF position.
NOTE: For vehicles equipped with Remote Start, the
climate controls will not function during Remote Start
operation if the blower control is left in the OFF position.
Temperature Control
Use this control to regulate the tem-
perature of the air inside the passenger
compartment. Rotating the knob coun-
terclockwise, from top center into the
blue area of the scale, indicates cooler temperatures. Rotating the knob clockwise, into the red
area, indicates warmer temperatures.
NOTE: If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser (located in front of the radiator), for an accumu-
lation of dirt or insects. Clean with a gentle water spray
from behind the radiator and through the condenser.
Fabric front fascia protectors may reduce airflow to the
condenser, reducing air conditioning performance.
Mode Control (Air Direction)
Mode control allows you to choose
from several patterns of air distribu-
tion. You can select either a primary
mode, as identified by the symbols, or
a blend of two of these modes. The
closer the control is to a particular
mode, the more air distribution you
receive from that mode. 4 UNDERSTANDING YOUR INSTRUMENT PANEL 257

Panel Mode
Air is directed through the outlets in the instrument
panel. These outlets can be adjusted to direct airflow.
Bi-Level Mode
Air is directed through the panel and floor outlets.
NOTE: There is a difference in temperature (in any
conditions other than full cold or full hot), between the
upper and lower outlets for added comfort. The warmer
air goes to the floor outlets. This feature gives improved
comfort during sunny but cool conditions.
Floor Mode
Air is directed through the floor outlets with a
small amount through the defrost and side window
demist outlets. Mix Mode
Air is directed through the floor, defrost and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat at
the windshield. This setting is good for maintaining
comfort, while reducing moisture on the windshield.
Defrost Mode
Air is directed through the windshield and side
window demist outlets. Use the DEFROST mode
with maximum blower and warm temperature settings
for best windshield and side window defrosting.
NOTE: The air conditioning compressor operates in
MIX and DEFROST, or a blend of these modes even if the
A/C button is not pressed. This dehumidifies the air to
help dry the windshield. To improve fuel economy, use
these modes only when necessary.258 UNDERSTANDING YOUR INSTRUMENT PANEL

Economy Mode
If ECONOMY mode is desired, press the A/C button to
turn off the LED indicator and the A/C compressor.
Rotate the temperature control knob to the desired
temperature.
Air Conditioning Operation
Push this button to engage the Air
Conditioning (A/C). A LED will illu-
minate when the A/C system is
engaged. MAX A/C
For maximum cooling, when MAX
A/C is selected the A/C is turned on
automatically and the air is recircu-
lated.
NOTE: A/C cannot be deselected when in MAX A/C
position. The LED will blink three times if the A/C
button is pushed.
Automatic Temperature Control (ATC) — If
Equipped
• The Automatic Temperature Control (ATC) allows
both driver and front passenger seat occupants to
