2018 Ram ProMaster oil temperature

— 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.

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.
NOTE:
Refer to the following chart for proper engine
shutdown.STARTING AND OPERATING
76

NOTE:
Do not press the brake and accelerator pedals
at the same time. Use only one foot to operate
the brake and accelerator.
To operate in DRIVE (D) (Automatic mode):
• Press and hold the brake pedal.
• Move the gear selector to the DRIVE (D)position.
NOTE:
If the vehicle is moving, DRIVE engagement
will only occur if the vehicle speed is less
than 2 mph (3 km/h). Otherwise, a chime will
sound, the transmission will shift to NEU-
TRAL, and the DRIVE request must then be
repeated by returning the lever to NEUTRAL
and then back into DRIVE once the speed has
been sufficiently reduced.
• To drive, release the brake pedal and press the accelerator pedal.
When in DRIVE (D) the transmission will shift
gears automatically. The Automated Manual
Transmission uses a geartrain and clutch
similar to other manual transmissions. There- fore, you should become familiar with some
of the normal operational characteristics of
the Automated Manual Transmission:
• Engine torque will be interrupted briefly
during the transmission upshifts, making
these shifts more abrupt than with a typical
automatic transmission. This is normal.
• Although transmission shifting is per- formed automatically, the vehicle will not
"creep" when the brake pedal is released,
and may in fact roll down on an incline.
Leaving from a stop, the accelerator pedal
must be pressed to transmit driving torque
to the wheels.
• In Automatic Mode, the Automated Manual Transmission adapts the gear changing
strategy evaluating the road condition such
as slopes in the road.
• During low-speed driving conditions in first gear, vehicle momentum changes may feel
exaggerated in response to changes in ac-
celerator pedal position. This behavior is
normal and is similar to other vehicles
equipped with manual transmissions. • At low speeds you may hear mechanical
noises similar to a manual transmission as
the transmission changes gears. These
noises are normal and will not damage the
transmission.
• Very aggressive driving may result in some clutch odor. A warning message will display
in the instrument cluster display if cool
down actions are needed.
• Before and after the engine is started, you may hear a hydraulic pump for a short
period of time. This noise is normal and will
not damage the transmission.
During extremely cold temperatures, the
transmission will not operate if the oil tem-
perature is -22°F (-30°C) or below. Normal
operation will resume once the transmission
temperature has risen to a suitable level.
When transmission actuation oil temperature
is lower than -22°F (-30°C), engine start will
not be allowed. For this reason the block
heater is recommended below -17°F (-27°C).

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
Change Required” message is displayed. Se-
vere Operating 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 pos-
sible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change
indicator message after completing the sched-
uled oil change. If a scheduled oil change is
performed by someone other than your autho-
rized dealer, the message can be reset byreferring to the steps described under “Instru-
ment Cluster Display” in “Getting To Know
Your Instrument Panel” in your Owner’s
Manual on
www.ramtrucks.com/en/owners/
manuals for further information.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
twelve months or 350 hours of engine run
time, whichever comes first. The 350 hours
of engine run or idle time is generally only a
concern for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles
(6,500 km) or 350 hours of engine run time
if the vehicle is operated in a dusty and off
road environment or is operated predomi-
nately at idle or only very low engine RPM’s.
This type of vehicle use is considered Severe
Duty. 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 reser- voir, brake master cylinder, and power
steering and fill as needed
• Check function of all interior and exterior lights
