2012 RAM CHASSIS CAB heating

WARNING! (Continued)• If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set
the blower at high speed.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required. Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding belt
or retractor condition, replace the belt.
Air Bag Warning Light
The light should come on and remain on for four to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer. 2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 79

WARNING! (Continued)• 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. Sitting in a
seat that has been overheated could cause serious
burns due to the increased surface temperature of
the seat.
Front Heated Seats
There are two heated seat switches that allow the driver
and passenger to operate the seats independently. The
controls for each seat are located near the bottom center
of the instrument panel (below the climate controls).
You can choose from HIGH, LOW or OFF heat settings.
Amber indicator lights in each switch indicate the level of
heat in use. Two indicator lights will illuminate for
HIGH, one for LOW and none for OFF. Press the switch once to select HIGH-
level heating. Press the switch a sec-
ond time to select LOW-level heating.
Press the switch a third time to shut
the heating elements OFF.
NOTE:
• Once a heat setting is selected, heat will be felt within
two to five minutes.
• The engine must be running for the heated seats to
operate.
The heated seats switch from HIGH to LOW and from
LOW to OFF automatically, based on time and tempera-
ture of the seat. The heated seats can operate on HIGH
heat for a maximum of 60 minutes before switching to
LOW heat. Once a seat has switched to the LOW heat
setting it may operate for a maximum of 45 minutes 3 UNDERSTANDING THE FEATURES OF YOUR VEHICLE 133

before automatically shutting OFF. The heated seats can
shut OFF early or may not turn on when the seat is
already warm.
Vehicle Equipped With Remote Start
On models that are equipped with remote start, the
driver ’s heated seat can be programmed to come on
during a remote start. Refer to “Remote Starting System
— If Equipped” in “Things to Know Before Starting Your
Vehicle” for further information.
Rear Heated Seats
On some models, the two outboard seats are equipped
with heated seats. The heated seat switches for these
seats are located on the rear of the center console.
There are two heated seat switches that allow the rear
passengers to operate the seats independently. You can
choose from HIGH, LOW or OFF heat settings. Amber indicator lights in each switch indicate the level of heat in
use. Two indicator lights will illuminate for HIGH, one
for LOW and none for OFF.
Press the switch once to select HIGH-
level heating. Press the switch a sec-
ond time to select LOW-level heating.
Press the switch a third time to shut
the heating elements OFF.
NOTE:
• Once a heat setting is selected, heat will be felt within
two to five minutes.
• The engine must be running for the heated seats to
operate.

be adjusted when the system is locked out (“Adjust-
able Pedal Disabled — Cruise Control Engaged” or
“Adjustable Pedal Disabled — Vehicle In Reverse”.
CAUTION!Do not place any article under the adjustable pedals
or impede its ability to move as it may cause damage
to the pedal controls. Pedal travel may become lim-
ited if movement is stopped by an obstruction in the
adjustable pedal’s path.
WARNING!Do not adjust the pedals while the vehicle is moving.
You could lose control and have an accident. Always
adjust the pedals while the vehicle is parked. HEATED STEERING WHEEL — IF EQUIPPED
The steering wheel contains a heating element that helps
warm your hands in cold weather. The heated steering
wheel has only one temperature setting. Once the heated
steering wheel has been turned on it will operate for
approximately 58 to 70 minutes before automatically
shutting off. The heated steering wheel can shut off early
or may not turn on when the steering wheel is already
warm.
The heated steering wheel switch is located on the switch
bank below the climate controls.
Press the switch to turn on the heated
steering wheel. The light on the switch
will illuminate to indicate the steering
wheel heater is on. Pressing the switch
a second time will turn off the heated
steering wheel and light indicator.3 UNDERSTANDING THE FEATURES OF YOUR VEHICLE 159

CAUTION!Failure to follow these cautions can cause damage to
the heating elements:
• Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to
the heating elements. Labels can be peeled off
after soaking with warm water.
• Do not use scrapers, sharp instruments, or abra-
sive window cleaners on the interior surface of the
window.
• Keep all objects a safe distance from the window.
Power Sliding Rear Window — If Equipped
The switch for the power sliding rear window is located
on the overhead console. Push the switch to the right to open the glass. Pull the
switch to the left to close the glass.
Manual Sliding Rear Window — If Equipped
A locking device in the center of the window helps to
prevent entry from the rear of the vehicle. Squeeze the
lock to release the window. Rear Window Switch

means the engine oil change interval may fluctuate
dependent upon your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON/RUN
position. To turn off the message temporarily, press and
release the Trip Odometer button on the instrument
cluster. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the
following procedure:
1. Turn the ignition switch to the ON/RUN position
(do not start the engine).
2. Fully depress the accelerator pedal slowly three
times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure. 15. Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. As engine coolant temperatures rise and the
gauge approaches H, this indicator will illuminate
and a single chime will sound after reaching a set
threshold. Further overheating will cause the tempera-
ture gauge to pass H, the indicator will continuously
flash and a continuous chime will occur until the engine
is allowed to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for further information.

cator will display in the Electronic Vehicle Information 4 UNDERSTANDING YOUR INSTRUMENT PANEL 195
