2016 Ram ProMaster City fuel cap

1. Speedometer•Indicates vehicle speed
2. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position
3. Temperature Gauge •The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather or up moun-
tain grades. It should not be allowed to exceed the
upper limits of the normal operating range.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”, turn the engine off immediately
and call an authorized 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
Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.

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.

time the vehicle is raised. Have any abnormal
conditions repaired promptly. Until repaired, drive
with all side windows fully open.
ADDING FUEL
The gas cap is located behind the fuel filler door on the
left side of the vehicle. If the gas cap is lost or damaged,
be sure the replacement cap is for use with this vehicle.
1. Open the fuel filler door.
2. Remove the fuel cap by rotating it counterclockwise.
3. Fully insert the gasoline nozzle into the filler pipe.
4. Fill the vehicle with fuel.
NOTE:When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.

5. Remove gasoline nozzle, reinstall fuel cap and closefuel filler door.
CAUTION!
•Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap. A poorly fitting cap could let
impurities into the fuel system and may cause the
“Malfunction Indicator Light (MIL)” to turn on,
due to fuel vapors escaping from the system.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
• Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
(Continued)
WARNING! (Continued)
•Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and may cause the MIL to turn on.
• A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
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.
290 STARTING AND OPERATING

•If the gas cap is not tightened properly, the MIL may
come on. Be sure the gas cap is tightened every time
the vehicle is refueled.
VEHICLE LOADING
As required by National Highway Traffic Safety Admin-
istration regulations, your vehicle has a certification label
affixed to the driver’s side door or B-Pillar.
If seats are removed for carrying cargo, do not exceed the
specified GVWR and GAWR.
Vehicle Certification Label
Your vehicle has a Vehicle Certification Label affixed to
the drivers side B-Pillar or the rear of the driver ’s door.
The label contains the following information:
• Name of manufacturer
• Month and year of manufacture •
Gross Vehicle Weight Rating (GVWR)
• Gross Axle Weight Rating (GAWR) front
• Gross Axle Weight Rating (GAWR) rear
• Vehicle Identification Number (VIN)
• Type of Vehicle
• Month Day and Hour of Manufacture (MDH)
The bar code allows a computer scanner to read the VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles

evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
Because the front wheels steer the vehicle, it is
important that you do not exceed the maximum front
or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose
control of the vehicle and have a collision.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and the
front and rear GAWR.

service of your vehicle and emissions system.
WARNING!
•ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the
OBD II connection port, such as a driver-behavior
tracking device, it may:
• Be possible that vehicle systems, including
safety related systems, could be impaired or a
loss of vehicle control could occur that may result
in an accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including per-
sonal information. For further information, refer to “Cybersecurity” in “Un-
derstanding Your Instrument Panel” in your Owner ’s
Manual on the DVD.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check fuel cap” message will be displayed in the
Electronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in ”Un-
derstanding Your Instrument Panel” for further informa-
tion. Tighten the gas cap until a
clickingsound is heard.
This is an indication that the gas cap is properly tight-
ened.
Push the odometer reset button to turn the message off. If
the problem persists, the message will appear the next
time the vehicle is started. This might indicate a damaged
