overheating Ram 2500 2011 Owner's Manual

WARNING!
•Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, ex-
haustion 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. Sitting in a
seat that has been overheated could cause serious
burns due to the increased surface temperature of
the seat.
CAUTION!
Repeated overheating of the seat could damage the
heating element and/or degrade the material 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.

Gate Operator/Canadian Programming
Canadian radio-frequency laws require transmitter sig-
nals to “time-out” (or quit) after several seconds of
transmission – which may not be long enough for
HomeLinkto pick up the signal during programming.
Similar to this Canadian law, some U.S. gate operators are
designed to “time-out” 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 “Programming
HomeLink” Step 3 with the following:
3.Continue to press and hold the HomeLinkbutton,
while you press and release (“cycle”), your handheld
transmitter every two seconds until HomeLinkhassuccessfully accepted the frequency signal.The EVIC
display will change from “CHANNEL # TRAINING” to
“CHANNEL # TRAINED.”
If you unplugged the device for training, plug it back in
at this time.
Then proceed with Step 4 under “Programming
HomeLink” earlier in this section.
Using HomeLink
To operate, press and release the programmed
HomeLinkbutton. Activation will now occur for the
trained device (i.e., garage door opener, gate operator,
security system, entry door lock, home/office lighting,
etc.,). The handheld transmitter of the device may also be
used at any time.

17. Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proachesH,this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
passH,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.
For vehicles equipped with a premium cluster this indi-
cator will display in the Electronic Vehicle InformationCenter (EVIC). Refer to ”Electronic Vehicle Information
Center (EVIC) — If Equipped” for further information.
18. Shift Lever Indicator
The Shift Lever Indicator is self-contained within the
instrument cluster. It displays the gear position of the
automatic transmission.
NOTE:In vehicles with 4.7L or 5.7L engines, the highest
available transmission gear is displayed in the lower
right corner of the Electronic Vehicle Information Center
(EVIC) whenever the Electronic Range Select (ERS) fea-
ture is active. Use the +/- selector on the shift lever to
activate ERS. Refer to “Automatic Transmission” in
“Starting And Operating” for further information.
19. Low Fuel Light
When the fuel level reaches approximately 3.0 gal
(11.0 L) this light will turn on, and remain on until
fuel is added.

If the light remains lit with the engine running your
vehicle, will usually be drivable, however, see an autho-
rized dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
required and you may experience reduced performance,
an elevated/rough idle or engine stall and your vehicle
may require towing.
•Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proachesH,this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
passH,the indicator will continuously flash and a
continuous chime will occur until the engine is allowed

Do In Emergencies” for more information.
•SERV 4WD
The SERV 4WD light monitors the electric shift
4WD system. If the SERV 4WD light stays on or
comes on during driving, it means that the
4WD system is not functioning properly and
that service is required.
•Electronic Stability Control (ESC) OFF Indicator

Recirculation Control
When outside air contains smoke, odors, or
high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the RECIRCULATION control button.
Recirculation mode should only be used temporarily. The
recirculation LED will illuminate on the blower control
knob when this button is selected. Push the button a
second time to turn off the Recirculation mode LED and
allow outside air into the vehicle.
NOTE:In cold weather, use of Recirculation mode may
lead to excessive window fogging. The Recirculation
mode is not allowed in the Floor/Defrost Mix and
Defrost modes to improve window clearing operation.
Recirculation will be disabled automatically if these
modes are selected.
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 15-
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.
WARNING!
Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Do not leave the key fob in
the ignition. A child could operate power windows,
other controls, or move the vehicle.
Normal Starting
Normal starting of either a warm or cold engine is
obtained without pumping or pressing the acceleratorpedal. Turn the key fob to the START position and release
when the engine starts. If the engine fails to start within
10 seconds, turn the key fob to the OFF position, wait five
seconds, then repeat the “Normal Starting” procedure.
Automatic Transmission
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting into any
driving range.
NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
pressed to shift out of PARK.
Tip Start Feature
Do notpress the accelerator. Turn the ignition switch
briefly to the START position and release it. The starter
motor will continue to run but will automatically disen-
gage when the engine is running.

performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in TOW/HAUL mode, the transmission will
shift to third gear and fourth gear will be enabled under
steady cruise conditions.The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the TOW/HAUL mode is desired,
the switch must be pressed each time the engine is
started.
Transmission Limp Home Mode
Transmission function is monitored for abnormal condi-
tions. If a condition is detected that could result in
transmission damage, the Transmission Limp Home
Mode will be engaged. In this mode, the transmission
will operate (when in DRIVE) in second gear only.
To reset the transmission, use the following procedure:
1. Stop the vehicle.
2. Move the shift lever to the PARK position.

performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in the TOW/HAUL mode, fifth gear is dis-
abled and 2-3 and 3-4 shift patterns are modified.
Shifts into Overdrive (fourth gear) are allowed during
steady cruise (for improved fuel economy) and automaticclosed-throttle downshifts to third gear are performed
(for improved braking) when driving conditions warrant.
The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the TOW/HAUL mode is desired,
the button must be pressed each time the engine is
started.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
acceleration when the transmission downshifts to second
gear, the clutch automatically disengages.

322 STARTING AND OPERATING

NOTE:
•Avoid overheating the winch motor. For extended
winching, stop at reasonable intervals to allow the
winch motor to cool down.
•What to look for under load:The wire rope must
always spool onto the drum as indicated by the drum
rotation decal on the winch. As you power-in, make
sure the wire rope winds evenly and tightly on the
drum. This prevents the outer wire wraps from draw-
ing into the inner wraps, binding and damaging the
wire rope. Avoid shock loads by using the control
switch intermittently to take up wire rope slack. Shock
loads can momentarily far exceed the winch and wire
rope ratings. During side pulls the wire rope tends to
stack up at one end of the drum. This stack can becomelarge enough to cause serious damage to the winch.
So, line up pulls as straight ahead as possible and stop
winching if the wire rope comes close to the tie rods or
mounting plate. To fix an uneven stack, spool out that
section of the rope and reposition it to the opposite end
of the drum, which will free up space for continued
winching.
16. Secure vehicle. Once recovery of the vehicle’s is
complete, be sure to secure the vehicle’s brakes and put
the transmission in PARK. Release tension in the wire
rope.
17. Disconnect the wire rope, and disconnect from the
anchor.

General Maintenance
Snowplows should be maintained in accordance with the
plow manufacturer’s instructions.
Keep all snowplow electrical connections and battery
terminals clean and free of corrosion.
When plowing snow, to avoid transmission and drive-
train damage, the following precautions should be ob-
served.
•Operate with transfer case in 4L when plowing small
or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4H.
•Vehicles with automatic transmissions should use 4L
range when plowing deep or heavy snow for extended
periods of time to avoid transmission overheating.
•Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal before shifting
the transmission.
