coolant Ram 1500 2015 Diesel Supplement

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence when the “Oil
Change Required” message is displayed. Severe Operat-
ing Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km) since last
reset. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone otherthan your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)” or “Driver Information Dis-
play (DID)” in “Understanding Your Instrument Panel”
for further information.
NOTE:
Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder and power steering, and fill as needed
• Check function of all interior and exterior lights

Remote Start Comfort Systems — If Equipped
When remote start is activated, the heated steering
wheel, and driver heated seat features will automatically
turn on in cold weather. In warm weather, the driver
vented seat feature will automatically turn on when the
remote start is activated. These features will stay on
through the duration of remote start or until the ignition
switch is turned to the ON position.
The Remote Start Comfort System can be activated and
deactivated through the EVIC/DID. For more informa-
tion on Remote Start Comfort System operation refer to
your Owners Manual.
ENGINE BREAK-IN RECOMMENDATIONS
The Cummins® turbocharged diesel engine does not
require a break-in period due to its construction. Normal
operation is allowed, providing the following recommen-
dations are followed:
•Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged
periods.
• Use the appropriate transmission gear to prevent
engine lugging.
• Observe vehicle oil pressure and temperature indica-
tors.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carry-
ing or towing significant weight.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 147

NOTE:
•A continuous chime will sound if the vehicle is driven
more than 1 mile (1.6 km) with either turn signal on.
• Check for an inoperative outside light bulb if either
indicator remains on and does not flash, or flashes at a
rapid rate.
5. Engine Coolant Temperature
This gauge shows the engine coolant temperature. The
gauge pointer will likely show higher temperatures when
driving in hot weather, up mountain grades, or in heavy
stop and go traffic. If the red Warning Light turns on
while driving, safely bring the vehicle to a stop, and turn
off the engine. DO NOT operate the vehicle until the
cause is corrected.CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your

Low Coolant Level Indicator
This telltale will turn on to indicate the vehicle
coolant level is low.
Cold Ambient Derate Mode Messages
The vehicle will display messages when a derate (engine
power reduction) is activated to protect the turbocharger
during engine start up in cold ambient temperatures.
•Engine Power Reduced During Warmup — This
message will display during start up when the ambi-
ent temperature is between 10° F (-12° C) and -10° F
(-23° C). •

Diesel Particulate Filter (DPF) Messages
The Cummins® diesel engine meets all EPA Heavy Duty
Diesel Engine Emissions Standards, resulting in one of
the lowest emitting diesel engines ever produced. To
achieve these emissions standards, your vehicle is
equipped with a state-of-the-art engine and exhaust
system. These systems are seamlessly integrated into
your vehicle and managed by the Powertrain Control
Module (PCM). The PCM manages engine combustion to
allow the exhaust system’s catalyst to trap and burn
Particulate Matter (PM) pollutants, with no input or
interaction on your part.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust

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.

2. While theWait To Start” telltale is on, the EVIC/DID
will additionally display a gauge or bar whose initial
length represents the full Wait To Starttime period.
Its length will decrease until it disappears when the
Wait To Start time has elapsed.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filters to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for fur-
ther information.
3. After the “Wait To Start” telltale goes off, turn the ignition switch to the START position. Do not press the
accelerator during starting.
CAUTION!
Do not crank engine for more than 15 seconds at a
time or starter motor damage may result. Turn the
ignition switch to the OFF position and wait at least
two minutes for the starter to cool before repeating
start procedure.
4. After engine start-up, check that the oil pressure warning light has turned off.
5. Allow the engine to idle about three minutes until the manifold heaters have completed the post-heat cycle.
6. 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.
