2015 Ram 1500 coolant level

NOTE:The “Wait To Start Light” may not illuminate if
the intake manifold temperature is warm enough.
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). •
Engine Power Reduced Up To 30 Sec (Seconds) During
Warmup
—This message will display during start up
when the ambient temperature is between -10° F (-23° C)
and -25 F (-32° C).
• Engine Power Reduced Up To 2 Min (Minutes)
During Warmup
— This message will display during
start up when the ambient temperature is -25° F (-32° C)
and below.
• Coolant Low — This telltale will turn on to indicate
the vehicle coolant level is low. See “Adding Coolant”
under the section “Maintaining Your Vehicle” for more
information.
Diesel Particulate Filter (DPF) Messages

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

(antifreeze) solution. The use of lower quality water
will reduce the amount of corrosion protection in the
engine cooling system.
Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE:
• Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system please contact your
local authorized dealer. •
Mixing engine coolant (antifreeze) types is not recom-
mended and can result in cooling system damage. If
HOAT and OAT coolant are mixed in an emergency,
have a authorized dealer drain, flush, and refill with
OAT coolant (conforming to MS.90032) as soon as
possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that the engine coolant
(antifreeze) will return to the radiator from the coolant
expansion bottle.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.

MAINTAINING YOUR VEHICLE 301

MAINTENANCE SCHEDULE — DIESEL ENGINE
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop For Fuel
Check the engine oil level at least 30 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accuracy
of the oil level reading. Add oil only when the level is at
or below the ADD or MIN mark. Once A Month
•
Inspect the batteries, and clean and tighten the termi-
nals as required.
• Check the fluid levels of the coolant reservoir, brake
master cylinder, and automatic transmission (if
equipped), and add as needed.
At Each Oil Change
• Change the engine oil filter.
• Inspect the exhaust system.
• Inspect engine air filter.
• Check the coolant level, hoses, and clamps.
• Lubricate outer tie rod ends.
