2016 Ram 2500 heating

•Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
pass H,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 PARK and idle
the vehicle. 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. •
Electric Power Steering Malfunction Warning Light
This telltale is on when the Electric Power
Steering is not operating and needs service.
• Trailer Brake Disconnected Warning Light
This telltale is on when the Trailer Brake has
been disconnected.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, both inside
and outside mirrors, and fasten your seat belts.
The starter is allowed to crank for up to 30-second
intervals. Waiting a few minutes between such intervals
will protect the starter from overheating.
WARNING!
•Before exiting a vehicle, always apply the parking
brake, shift the automatic transmission into PARK
or the manual transmission into REVERSE. Always
make sure the keyless ignition node is in the “OFF”
mode, remove the Key Fob from the vehicle and
lock the vehicle.

WARNING! (Continued)
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children in
a vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
• Do not leave the Key Fob in or near the vehicle (or
in a location accessible to children), and do not
leave the ignition of a vehicle equipped with
Keyless Enter-N-Go in the ACC or ON/RUN mode.
A child could operate power windows, other con-
trols, or move the vehicle.
NOTE: Engine start up in very low ambient temperature
could result in evident white smoke. This condition will
disappear as the engine warms up.

3. The system will automatically engage the starter tocrank the engine. If the vehicle fails to start, the starter
will disengage automatically after 25 seconds.
4. If you wish to stop the cranking of the engine prior to the engine starting, push the button again.
5. Check that the oil pressure warning light has turned off.
6. Release the parking brake.
Extreme Cold Weather
The engine block heater is a resistance heater installed in
the water jacket of the engine. It requires a 110–115 Volt
AC electrical outlet with a grounded, three-wire exten-
sion cord. Its use is recommended for environments that
routinely fall below -10°F (-23°C). It should be used when
the vehicle has not been running overnight or longer periods and should be plugged in two hours prior to
start. Its use is required for cold starts with temperatures
under -20°F (-28°C).
NOTE: The engine block heater cord is a factory in-
stalled option. If your vehicle is not equipped, heater
cords are available from your authorized MOPAR
dealer.
•
A 12 Volt heater built into the fuel filter housing aids in
preventing fuel gelling. It is controlled by a built-in
thermostat.
• A Diesel Pre-Heat system both improves engine start-
ing and reduces the amount of white smoke generated
by a warming engine.
Starting Fluids
The engine is equipped with a glow plug preheating
system. If the instructions in this manual are followed,
100 STARTING AND OPERATING

NORMAL OPERATION
Observe the following when the diesel engine is operat-
ing.
•All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Engine Oil Pressure telltale is not illuminated.
• Voltmeter operation:
The voltmeter may show a gauge fluctuation at various
engine temperatures. This is caused by the glow plug
heating system. The number of cycles and the length of
the cycling operation is controlled by the engine control
module. Glow plug heater operation can run for several
minutes, once the heater operation is complete the volt-
meter needle will stabilize.
Cold Weather Precautions
Operation in ambient temperature below 32°F (0°C) may
require special considerations. The following charts sug-
gest these options:

NOTE: Use “Ultra Low Sulfur Diesel Fuels” ONLY.
*No. 1 Ultra Low Sulfur Diesel Fuel should only be used
where extended arctic conditions (-10°F/-23°C) exist.

102 STARTING AND OPERATING

Cooling System Tips — Automatic Transmission
To reduce the potential for engine and transmission
overheating in high ambient temperature conditions,
take the following actions:
•City Driving — When stopped, shift the transmission
into NEUTRAL and increase engine idle speed.
• Highway Driving — Reduce your speed.
• Up Steep Hills — Select a lower transmission gear.
• Air Conditioning — Turn it off temporarily.
NOTE: If the coolant temperature is too high the A/C
will automatically turn off.
Do Not Operate The Engine With Low Oil
Pressure
If the low oil pressure warning light turns on while
driving, stop the vehicle and shut down the engine as
soon as possible. A chime will sound when the light turns
on.
NOTE: Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is in the
engine. The engine oil level must be checked under the
hood.
CAUTION!
If oil pressure falls to less than normal readings, shut
the engine off immediately. Failure to do so could
result in immediate and severe engine damage.
106 STARTING AND OPERATING

CAUTION!(Continued)
•Never add anything other than DEF to the tank –
especially any form of hydrocarbon such as diesel
fuel, fuel system additives, gasoline, or any other
petroleum-based product. Even a very small
amount of these (less than 100 parts per million or
less than 1 oz. per 78 gallons) will contaminate the
entire DEF system and will require replacement. If
owners use a container, funnel or nozzle when
refilling the tank, it should either be new or one
that is has only been used for adding DEF. MOPAR
provides an attachable nozzle with its DEF for this
purpose.
3. Stop filling the DEF tank immediately when any of the following happen: DEF stops flowing from the fill
bottle into the DEF tank, DEF splashes out the filler
neck, or a DEF pump nozzle automatically shuts off. 4. Reinstall cap onto DEF tank.
Filling The Def Tank In Cold Climates
Since DEF will begin to freeze at 12°F (-11°C), your
vehicle is equipped with an automatic DEF heating
system. This allows the DEF injection system to operate
properly at temperatures below 12°F (-11°C). If your
vehicle is not in operation for an extended period of time
with temperatures below 12°F (-11°C), the DEF in the
tank may freeze. If the tank is overfilled and freezes, it
could be damaged. Therefore, do not overfill the DEF
tank.
Extra care should be taken when filling with portable
containers to avoid overfilling. Note the level of the DEF
gauge in your instrument cluster. On pickup applica-
tions, you may safely add a maximum of 2 gallons of DEF
from portable containers when your DEF gauge is read-
ing ½ full.
