2018 Ram ProMaster low oil pressure

— Engine Temperature Warning Light
This light warns of an overheated engine
condition. If the engine coolant temperature
is too high, this indicator will illuminate and
a single chime will sound.
If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is
on, turn it off. Also, shift the transmission
into NEUTRAL and idle the vehicle. If the
temperature reading does not return to nor-
mal, turn the engine off immediately and call
for service. Refer to “If Your Engine Over-
heats” in “In Case Of Emergency” for further
information.
— Oil Pressure Warning Light
This light indicates low engine oil pressure. If
the light turns on while driving, stop the
vehicle and shut off the engine as soon as
possible. A chime will sound when this light
turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how
much oil is in the engine. The engine oil level
must be checked under the hood.
— Seat Belt Reminder Warning Light
When the ignition is first placed in the ON/
RUN or MAR/ON/RUN position, if the driver’s
seat belt is unbuckled, a chime will sound
and the light will turn on. When driving, if the
driver or front passenger seat belt remains
unbuckled, the Seat Belt Reminder Light will
flash or remain on continuously and a chime
will sound. Refer to “Occupant Restraints
Systems” in “Safety” for further information.
— Transmission Fault Warning Light
This light will illuminate (together with a
message in the instrument cluster display
and a buzzer) to indicate a transmission
fault. Contact your authorized dealer if the
message remains after restarting the engine.
For vehicles with a diesel engine, see "Instru-
ment Cluster Messages" in "Automated
Manual Transmission" for additional informa-
tion.
— Transmission Temperature Warning
Light — If Equipped
This light indicates high transmission fluid
temperature. This may occur with strenuous
usage such as trailer towing. If this light turns on, stop the vehicle and run the engine at idle
or slightly faster, with the transmission in
PARK or NEUTRAL, until the light turns off.
Once the light turns off, you may continue to
drive normally.
WARNING!
If you continue operating the vehicle when
the Transmission Temperature Warning
Light is illuminated you could cause the
fluid to boil over, come in contact with hot
engine or exhaust components and cause
a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated
will eventually cause severe transmission
damage or transmission failure.
GETTING TO KNOW YOUR INSTRUMENT PANEL
36

Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicle
should be serviced if the light stays on
through several 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 serviced as soon as possible if this
occurs.
WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.
This could result in death or serious injury
to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the vehicle control system. It also
could affect fuel economy and driveability.
If the MIL is flashing, severe catalytic
converter damage and power loss will soon
occur. Immediate service is required.
— Anti-Lock Brake (ABS) Warning
Light
This light monitors the Anti-Lock Brake Sys-
tem (ABS). The light will turn on when the
ignition is placed in the ON/RUN or MAR/ON/
RUN position and may stay on for as long as
four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the
brake system is not functioning and service is
required. However, the conventional brake
system will continue to operate normally if
the brake warning light is not on. If the ABS light is on, the brake system
should be serviced as soon as possible to
restore the benefits of Anti-Lock Brakes. If
the ABS light does not turn on when the
ignition is placed in the ON/RUN or MAR/ON/
RUN position, have the light inspected by an
authorized dealer.
— Generic Warning Light
The Generic Warning Light will illuminate if
any of the following conditions occur: Engine
Oil Pressure Sensor Failure, External Light
Failure, Fuel Cut-Off intervention or fail,
Parking Sensor Failure, DST System Failure.
The telltale will remain on fixed in case of
swivel seat failure and on blinking in case of
Air Bag Warning Light Failure. Contact an
authorized dealer immediately for service.
39

CAUTION!
If the “Generic Warning Light” remains on
and a “Service Fuel Filter” message dis-
plays, DO NOT START engine before you
drain the water from the fuel filter housing
to avoid engine damage. Please see your
authorized dealer for draining the fuel
filter/water separator and fuel filter re-
placement.
Normal Starting Procedure
The gear selector must be in the NEUTRAL
(N) position, and the brake pedal must be
pressed, to allow engine cranking. Place the
gear selector in NEUTRAL (N) and apply the
brake pedal BEFORE turning the key to the
START/AVV position; otherwise, the engine
will not crank and the key must be cycled
OFF, then back on, before cranking is al-
lowed.
Observe the instrument panel cluster lights
when starting the engine.NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal.
1. Press and hold the brake pedal.
2. Place the gear selector into the NEUTRAL
(N) position while keeping the brake pedal
depressed.
3. Turn the ignition switch to the ON/RUN/ MAR position and watch the instrument
panel cluster lights.CAUTION!
If the “Generic Warning Light” remains on
and a “Service Fuel Filter” message dis-
plays, DO NOT START engine before you
drain the water from the fuel filter housing
to avoid engine damage. Please see your
authorized dealer for draining the fuel
filter/water separator and fuel filter re-
placement.
4. After the Glow Plug light turns off, turn the ignition switch to the AVV (START)
position to start the engine. Do not press
the accelerator during starting. 5. If you wish to stop the cranking of the
engine prior to the engine starting, release
the ignition key so that it turns back to the
ON/RUN position.
6. Check that the oil pressure warning light has turned off.
7. Release the parking brake.
To start the engine if the transmission is
faulty, the “Delayed startup” procedure may
be required.
NOTE:
Not all Transmission Failures requires the
“Delayed startup” Procedure, it depends on
the type of failure.(refer to "Instrument Clus-
ter Messages" under "Automated Manual
Transmission" in this section for further infor-
mation):
• Begin with the key in the OFF position.
• Press and hold the brake pedal.
• Turn the key to the START/AVV position and hold it there for at least seven seconds with
the brake depressed. The engine will start,
and the transmission will operate in recov-
ery mode (maximum gear permitted = 3rd,
75

automatic mode not available). If the en-
gine does not start, contact your authorized
dealer.
Extreme Cold Weather
Your vehicle may be equipped with three
heating elements; one engine block heater (a
resistance heater installed in the water jacket
of the engine) and two transmission heaters
(one resistance heater installed under the oil
reservoir of the hydraulic actuation system
and one on the differential cover of the trans-
mission). To ensure reliable starting/
operating in extreme cold temperatures, use
of an externally powered electric engine
block/transmission heater (available from
your authorized dealer) is recommended.
They require a 110–115 Volt AC electrical
outlet with a grounded, three-wire extension
cord. Their use is recommended for environ-
ments that routinely fall below -10°F
(-23°C). They should be used when the ve-
hicle has not been running overnight or lon-
ger periods and should be plugged in two
hours prior to start. Their use is required for
cold starts with temperatures under -17°F
(-27°C).NOTE:
The engine is designed to work at an ambient
temperature ranging from -22°F to + 122°F
(-30°C to + 50C°). Rubber, pipes, timing belt
cover and electronic devices are not designed
to work out of this range.
In the case of LOW temperature after Start-
ing, the Automated Manual Transmission
may not be able to engage first gear. In this
case a message "Shift not allowed" appears.
In this situation use the engine block heater.
NOTE:
The engine and transmission block heater
cord is a factory installed option. If your
vehicle is not equipped, heater cords are
available from your authorized Mopar dealer.
• A 12 Volt heater built into the fuel filter
housing aids in preventing fuel gelling. It is
controlled by a built-in thermostat.
• A Diesel Pre-Heat system both improves engine starting and reduces the amount of
white smoke generated by a warming
engine.
NORMAL OPERATION
Observe the following when the diesel engine
is operating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Generic Warning Light is off.
• Engine Oil Pressure telltale is notilluminated.
Stopping The Diesel Engine
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricat-
ing oil and coolant to carry excess heat away
from the combustion chamber, bearings, in-
ternal components, and turbocharger. This is
especially important for turbocharged diesel
engines.

ENGINE BREAK-IN RECOMMENDATIONS
— GASOLINE ENGINE
A long break-in period is not required for the
engine and drivetrain (transmission and axle)
in your vehicle. Drive moderately during the first 300 miles
(500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable.
While cruising, brief full-throttle acceleration
within the limits of local traffic laws contrib-
utes to a good break-in. Wide-open throttle
acceleration in low gear can be detrimental
and should be avoided.
The engine oil installed in the engine at the
factory is a high-quality energy conserving
type lubricant. Oil changes should be consis-
tent with anticipated climate conditions un-
der which vehicle operations will occur. For
the recommended viscosity and quality
grades, refer to “Fluids And Lubricants” in
“Technical Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.
NOTE:
A new engine may consume some oil during
its first few thousand miles (kilometers) of
operation. This should be considered a nor-
mal part of the break-in and not interpreted
as a problem. Please check your oil level with
the engine oil indicator often during the
break in period. Add oil as required.
ENGINE BREAK-IN RECOMMENDATIONS
– DIESEL ENGINE
The diesel engine does not require a break-in
period due to its construction. Normal opera-
tion is allowed, providing the following rec-
ommendations are followed:
• Warm up the engine before placing it under
load.
• Do not operate the engine at idle for pro- longed periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and tempera- ture indicators.
• Check the coolant and oil levels frequently.

SCHEDULED SERVICING — GASOLINE
ENGINE
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 in
the instrument cluster. This means that ser-
vice is required for your vehicle. Operating
conditions such as frequent short-trips,
trailer tow, and extremely hot or cold ambient
temperatures will influence when the “Oil
