2016 Ram ProMaster fuel cap

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
Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.
5. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
WARNING AND INDICATOR LIGHTS
IMPORTANT: The warning light switches on in the
instrument panel together with a dedicated message
and/or acoustic signal when applicable. These indica-
tions 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.

Engine Check/Malfunction Indicator Light (MIL)
Yellow TelltaleLight What It Means
Engine Check/Malfunction Indicator Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine and automatic transmission control systems. The
light will illuminate when the ignition is in the ON position before engine start. If the bulb
does not come on when turning the key from OFF to ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing gas cap, poor quality fuel, etc., may illuminate
the light after engine start. The vehicle should be serviced if the light stays on through sev-
eral typical driving styles. In most situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the MIL may flash to alert serious conditions that could lead to
immediate loss of power or severe catalytic converter damage. The vehicle should be ser-
viced as soon as possible if this occurs.

Fuel Water Separation — Must Use Mopar
Approved Fuel Filter Elements
Biodiesel fuel has a natural affinity to water and water
accelerates microbial growth. Your Mopar filtration sys-
tem is designed to provide adequate fuel water separa-
tion capabilities.
Fuel In Oil Dilution — Must Adhere To Required
Oil Change
Fuel dilution of lubricating oil has been observed with
the use of biodiesel fuel. Fuel in oil must not exceed 5%.
To ensure this limit is met your oil change interval must
be maintained with in the suggested schedule.
The regular use of biofuels greater than 5% and less than
20% require intervals shorter than the outlined 18,500 miles
(29 773 km) and must not exceed the suggested schedule.
When routinely operating on biofuels greater that 5% and
less than 20%, oil and filter replacement intervals must not
exceed 10,000 miles (16 093 km) or 6 months, which ever
comes first.
Biodiesel Fuel Filter Change Intervals
The use of biofuels require intervals shorter than the
outlined 30,000 miles (48 280 km) and must not exceed
the suggested schedule. When operating on biofuels
greater that 5% and less than 20%, fuel filter replacement
intervals must not exceed 20,000 Miles (40 233 km).
NOTE:
•Under no circumstances should oil change intervals
exceed 10,000 miles (16 093 km) or 6 months, if regular
operation occurs with greater than 5% and less than
20% biodiesel blends.
•
Under no circumstances should fuel filter intervals
exceed 20,000 miles (40 233 km), if regular operation
occurs with greater than 5% and less than 20% biodiesel
blends.

STARTING AND OPERATING 81

CAUTION!
Failure to comply with these Oil Change and fuel
filter requirements for vehicles operating on bio-
diesel blends up to B20 may result in premature
engine wear. Such wear is not covered by the New
Vehicle Limited Warranty. The engine may suffer
severe damage if operated with concentrations of
biodiesel higher than 20%.
ADDING FUEL
The fuel cap is located behind the fuel filler door on the
left side of the vehicle. If the fuel cap is lost or damaged,
be sure the replacement cap is for use with this vehicle.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.

2 — Diesel Exhaust Fluid (DEF) Fill Location
82 STARTING AND OPERATING

NOTE:
•When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
• Tighten the fuel filler cap until you hear a “clicking”
sound. This is an indication that the fuel filler cap is
properly tightened.
• Make sure that the fuel filler cap is tightened each time
the vehicle is refueled.
WARNING!
A fire may result if fuel is pumped into a portable
container that is on a truck bed. You could be burned.
Always place fuel containers on the ground while
filling.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper main-
tenance of the engine fuel filter and fuel tank is essential.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for further information.
Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated with
water will promote the growth of “microbes.” These
microbes form “slime” that will clog the fuel filtration
system and lines. Drain condensation from the supply
tank and change the line filter on a regular basis.
NOTE: When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system.

DEF Fill Procedure
NOTE:Refer to “Fluids, Lubricants, And Genuine Parts”
in “Maintaining Your Vehicle” for the correct fluid type. 1. Remove cap from DEF filler neck (located on drivers
side of the vehicle in the fuel door).
2. Insert DEF fill adapter/nozzle into DEF tank filler neck.
CAUTION!
•To avoid DEF spillage, and possible damage to the
DEF tank from overfilling, do not “top off” the DEF
tank after filling.
• DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point, how-
ever, if the tank is overfilled and freezes, the
system could be damaged.
• When DEF is spilled, clean the area immediately
with water and use an absorbent material to soak
up the spills on the ground.

STARTING AND OPERATING 85

CAUTION!(Continued)
•Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank as it can
result in severe damage to your engine, including
but not limited to failure of the fuel pump and
injectors.
• 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.
• DEF pump nozzle automatically shuts off.
4. Reinstall cap onto DEF filler neck.
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.
