2016 Ram 2500 heater

REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE:
• The vehicle must be equipped with an automatic
transmission to be equipped with Remote Start.
• The Remote Start system will wait for the “Wait To
Start” telltale to extinguish before cranking the engine.
This allows time for the intake heater to pre-heat the
incoming air, and is normal operation in cold weather.
Refer to “Wait To Start” in “Understanding Your
Instrument Panel”.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
• Transmission in PARK
• Doors closed
• Hood closed
• HAZARD switch off
• BRAKE switch inactive (brake pedal not pushed)
• Ignition key removed from ignition switch
• Battery at an acceptable charge level
• RKE PANIC button not pushed
170 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

will chirp twice (if programmed). In cold ambient tem-
perature conditions, the diesel vehicle may delay crank
up to 30 seconds for the fuel and grid heater. Once the
vehicle has started, the engine will run for 15 minutes or
75 seconds in extreme cold and high elevation.
NOTE:
•The park lamps will turn on and remain on during
Remote Start mode.
• For security, power window and power sunroof op-
eration (if equipped) are disabled when the vehicle is
in the Remote Start mode.
• The engine can be started two consecutive times (two
15-minute cycles) with the RKE transmitter. However,
the ignition switch must be cycled to the ON position
before you can repeat the start sequence for a third
cycle.To Exit Remote Start Mode Without Driving The
Vehicle
Push and release the REMOTE START button one time or
allow the engine to run for the entire fifteen minute cycle.
NOTE: To avoid unintentional shut downs, the system
will disable the one time push of the REMOTE START
button for two seconds after receiving a valid Remote
Start request.
To Exit Remote Start Mode And Drive The Vehicle
To exit Remote Start Mode and drive the vehicle before
the end of the 15-minute cycle, push and release the
unlock button on the RKE transmitter to unlock the door
and disarm the Vehicle Security Alarm System (if
equipped). Then, prior to the end of the 15-minute cycle,
cycle the ignition to the ON/RUN position.
172 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:
•The gauge may take up to five seconds to update after
adding a gallon or more of Diesel Exhaust Fluid (DEF)
to the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See
your authorized dealer for service.
• The DEF gauge may also not immediately update after
a refill if the temperature of the DEF fluid is below 12F
(-11C). The DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update after a period
of run time. Under very cold conditions, it is possible
that the gauge may not reflect the new fill level for
several drives. •
Outside temperature can affect DEF consumption. In
cold conditions, 12° F (-11° C) and below, the DEF
gauge needle can stay on a fixed position and may not
move for extended periods of time. This is a normal
function of the system.

IMPORTANT: The warning / indicator light switches on
in the instrument panel together with a dedicated mes-
sage and/or acoustic signal when applicable. These
indications are indicative and precautionary and as such
must not be considered as exhaustive and/or alternative
to the information contained in the Owner Manual,
which you are advised to read carefully in all cases.
Always refer to the information in this chapter in the
event of a failure indication.
All active telltales will display first if applicable. The
system check menu may appear different based upon
equipment options and current vehicle status. Some
telltales are optional and may not appear.

NOTE:The battery voltage may show a fluctuation at
various engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of the
cycling operation is controlled by the engine control
module. Post-heat operation can run for several minutes,
and then the electrical system and voltmeter needle will
stabilize.

258 STARTING AND OPERATING

NOTE:If the ignition switch is left in the ACC or RUN
(engine not running) position and the transmission is in
PARK, the system will automatically time out after 30
minutes of inactivity and the ignition will switch to the
OFF position.
ENGINE START/STOP Button Functions — With
Driver ’s Foot OFF The Brake Pedal (In PARK Or
NEUTRAL Position)
The ENGINE START/STOP button operates similar to an
ignition switch. It has three positions, OFF, ACC, RUN.
To change the ignition switch positions without starting
the vehicle and use the accessories follow these steps:
1. Starting with the ignition in the OFF position:
2. Push the ENGINE START/STOP button once to change the ignition to the ACC position. 3. Push the ENGINE START/STOP button a second time
to change the ignition to the RUN position.
4. Push the ENGINE START/STOP button a third time to return the ignition to the OFF position.
Keyless Enter-N-Go Starting Procedure — Engine
Manifold Air Temperature 0° F To 66° F (–18° C to
19° C)
NOTE: The temperature displayed in the Electronic
Vehicle Information Center (EVIC) or Driver information
Display (DID) does not necessarily reflect the engine
manifold air temperature. Refer to “Electronic Vehicle
Information Center (EVIC)” or Driver Information Dis-
play (DID)” in “Understanding Your Instrument Panel”
for further information. When engine temperatures fall
below 66°F (19°C) the “Wait To Start Light” will remain
on indicating the intake manifold heater system is active.5
STARTING AND OPERATING 263

5. After engine start-up, check to see that there is oilpressure.
6. Allow the engine to idle about three minutes until the manifold heaters have completed the post-heat cycle.
7. Release the parking brake and drive.
NOTE:
• Engine idle speed will automatically increase to 1,000
RPM and engage the Variable Geometry Turbocharger
at low coolant temperatures to improve engine warm-
up.
• The engine may not automatically crank after the
engine Wait To Start telltale goes off if a door or the
hood is ajar.
• If the engine stalls, or if the ignition switch is left ON
for more than two minutes after the “Wait To Start
Light” goes out, reset the grid heaters by turning the ignition switch to the OFF position for at least five
seconds and then back ON. Repeat steps 1 through 7 of
“Keyless Enter-N-Go Starting Procedure – Engine
Manifold Air Temperature Below 66° F (19° C).”
Extreme Cold Weather
The Cummins diesel engine is equipped with several
features designed to assist cold weather starting and
operation:
•
The engine block heater is a resistance heater installed
in the water jacket of the engine just above and behind
the oil filter. It requires a 110–115 Volt AC electrical
outlet with a grounded, three-wire extension cord.
NOTE: The engine block heater cord is a factory installed
option. If your vehicle is not equipped, heater cords are
available from your authorized MOPAR dealer.
