heater Ram 2500 2016 Diesel Supplement

NOTE:Excessive white smoke and poor engine perfor-
mance will result if manifold heaters are not recycled.
2. Heat generated by the manifold heaters dissipates rapidly in a cold engine. If more than two minutes
pass between the time the “Wait To Start” telltale turns
off and the engine is started, recycle the manifold
heaters by turning the ignition switch to the OFF
position for at least five seconds and then back ON.
3. If the vehicle is driven and vehicle speed exceeds 19 mph (31 km/h) before the manifold heater post-
heat (after start) cycle is complete, the manifold heat-
ers will shut off.
4. If the engine is started before the “Wait To Start” telltale turns off, the preheat cycle will turn off.
5. If the engine is cranked for more than 10 seconds, the post-heat cycle will turn off. 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.
• When a diesel engine is allowed to run out of fuel or
the fuel gels at low temperatures, air is pulled into the
fuel system. If your engine has run out of fuel, refer to
“Maintenance Procedures/Priming If The Engine Has
Run Out Of Fuel” in “Maintaining Your Vehicle” for
further information.
• If the engine stalls, or if the ignition switch is left ON
for more than two minutes after the “Wait To Start”
telltale 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 5 of
“Starting Procedure – Engine Manifold Air Tempera-
ture Below 66°F (19°C).”
270 STARTING AND OPERATING

WARNING!(Continued)
•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
controls, or move the vehicle.
NORMAL OPERATION — DIESEL ENGINE
Observe the following when the engine is operating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Engine oil pressure is above 10 psi (69 kPa) at idle. •
Voltmeter operation:
The voltmeter may show a gauge 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.
The cycling action will cause temporary dimming of the
headlamps, interior lamps, and also a noticeable reduc-
tion in blower motor speed.
272 STARTING AND OPERATING

Do Not Operate The Engine With Low Oil
Pressure
When the engine is at normal operating temperature, the
minimum oil pressures required are:
Idle 700 to 800 RPM 10 psi (69 kPa)
Full speed and load 30 psi (207 kPa)
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.
Do Not Operate The Engine With Failed Parts
All engine failures give some warning before the parts
fail. Be on the alert for changes in performance, sounds,
and visual evidence that the engine requires service.
Some important clues are:•
Engine misfiring or vibrating severely.
• Sudden loss of power.
• Unusual engine noises.
• Fuel, oil or coolant leaks.
• Sudden change, outside the normal operating range, in
the engine operating temperature.
• Excessive smoke.
• Oil pressure drop.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the heater
cord to a ground-fault interrupter protected 110–115 Volt
AC electrical outlet with a grounded, three-wire exten-
sion cord.
280 STARTING AND OPERATING

The engine block heater cord is routed under the hood to
the right side and can be located just behind the grille
near the headlamp.
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.
The block heater must be plugged in at least one hour to
have an adequate warming effect on the coolant.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110–115 Volt electrical cord could
cause electrocution.
NOTE: The block heater will require 110 Volts AC and 6.5
Amps to activate the heater element.
Block Heater Usage
For ambient temperatures below 0°F (-18°C), engine
block heater usage is recommended.
For ambient temperatures below –20°F (-29°C), engine
block heater usage is required.
DIESEL EXHAUST BRAKE (ENGINE BRAKING)
The purpose of the exhaust brake (engine braking) fea-
ture is to supply negative (braking) torque from the
engine. Typically, the engine braking is used for, but not
limited to, vehicle towing applications where vehicle
braking can be achieved by the internal engine power,
thereby sparing the mechanical brakes of the vehicle.
Benefits of the exhaust brake are:
• Vehicle driving control.
• Reduced brake fade.

STARTING AND OPERATING 281

JUMP STARTING
WARNING!
•To prevent personal injury or damage to clothing,
do not allow battery fluid to contact eyes, skin or
fabrics. Do not lean over a battery when connecting
jumper cables or allow cable clamps to touch each
other. Keep open flames or sparks away from
battery vent holes. Always wear eye protection
when working with batteries.
• Do not use a booster battery or any other booster
source that has a greater than 12 Volt system, i.e., do
not use a 24 Volt power source.
NOTE: Replacement batteries should both be of equal
size to prevent damage to the vehicle’s charging system.
Your vehicle is equipped with two 12 Volt batteries. If it
becomes necessary to use a booster battery with jumper cables to start a vehicle’s engine because its batteries are
discharged, the following procedure should be used:
Set the parking brake and place an automatic transmis-
sion in PARK (or NEUTRAL for a manual transmission).
Turn off lights, heater and other electrical loads. Observe
charge indicator (if equipped) in both batteries. If the
indicator (if equipped) is light or yellow on either battery,
replace that battery.
CAUTION!
Use the jump start procedure only when the charge
indicator (if equipped) in both batteries is dark in the
center. Do not attempt jump starting when either
battery charge indicator (if equipped) is bright or
yellow. If the charge indicator (if equipped) has a
green dot in the center, failure to start is not due to a
discharged battery and cranking system should be
checked.
