2018 Ram ProMaster engine overheat

NOTE:
• If fog or mist appears on the windshield orside glass, select Defrost mode and in-
crease blower speed if needed.
• If your air conditioning performance seems lower than expected, check the front of the
A/C condenser (located in front of the ra-
diator), for an accumulation of dirt or in-
sects. Clean with a gentle water spray from
the front of the radiator and through the
condenser.
Recirculation
When outside air contains smoke, odors, or
high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the Recirculation control button.
The recirculation indicator will illuminate
when this button is selected. Press the button
a second time to turn off the Recirculation
mode and allow outside air into the vehicle. NOTE:
In cold weather, use of recirculation mode
may lead to excessive window fogging. On
systems with Manual Climate Controls, the
Recirculation mode is not allowed in Defrost
mode to improve window clearing operation.
Recirculation will be disabled automatically
if this mode is selected. Attempting to use
Recirculation while in this mode will cause
the LED in the control button to blink and
then turn off.
Operating Tips
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to pro-
vide proper corrosion protection and to pro-
tect against engine overheating. A solution of
50% OAT (Organic Additive Technology) cool-
ant that meets the requirements of FCA Ma-
terial Standard MS.90032 and 50% water is
recommended. Refer to “Dealer Service” in
“Servicing And Maintenance” for proper
coolant selection.
Winter Operation
Use of the air Recirculation mode during
winter months is not recommended because
it may cause window fogging.
Vacation Storage
Any time you store your vehicle or keep it out
of service (i.e., vacation) for two weeks or
more, run the air conditioning system at idle
for about five minutes in the fresh air and
high blower setting. This will ensure ad-
equate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
Window Fogging
Interior fogging on the windshield can be
quickly removed by turning the mode selector
to Defrost. The Defrost/Floor mode can be
used to maintain a clear windshield and pro-
vide sufficient heating. If side window fog-
ging becomes a problem increase blower
speed. Vehicle windows tend to fog on the
inside in mild but rainy or humid weather.

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.

adjust both inside and outside mirrors, and
fasten your seat belts.
WARNING!
• Never leave children alone in a vehicle,or with access to an unlocked vehicle.
• Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
• Do not leave the key fob in or near the
vehicle (or in a location accessible to
children). A child could operate power
windows, other controls, or move the
vehicle.
Normal Starting
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal.
Turn the ignition switch to the AVV (START)
position and release it when the engine
starts. If the engine fails to start within
10 seconds, turn the ignition switch to the
STOP (OFF/LOCK) position, wait 10 to
15 seconds, then repeat the “Normal Start-
ing” procedure.
STARTING THE ENGINE — DIESEL
ENGINE
Before starting your vehicle, adjust your seat,
both inside and outside mirrors, and fasten
your seat belts.
The starter is allowed to crank for up to
10-second intervals. Waiting a few minutes
between such intervals will protect the starter
from overheating.
WARNING!
• Never leave children alone in a vehicle,or with access to an unlocked vehicle.
• Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
• Do not leave the key fob in or near the
vehicle (or in a location accessible to
children). A child could operate power
windows, other controls, or move the
vehicle.
NOTE:
Engine start up in very low ambient tempera-
ture could result in evident white smoke. This
condition will disappear as the engine warms
up.
STARTING AND OPERATING
74

Manual (M) (Manual Mode)
In the MANUAL (M) position the driver is
responsible for choosing the best gear ratio to
engage, depending on driving conditions.
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 MANUAL (M) mode:
• Press and hold the brake pedal.
• Move the gear selector to the MANUAL (M)position. The current gear will be displayed
in the instrument cluster.
• To drive, release the brake pedal and press the accelerator pedal.
• Tap the gear selector towards the (+) to engage a higher gear.
• Tap the gear selector towards the (–) posi- tion to engage a lower gear.
• The accelerator pedal need not be released during gear changes in MANUAL mode. • You can shift between DRIVE (D) and
MANUAL (M) positions at any speed, with-
out taking your foot off the accelerator
pedal.
• The system will shift down through the gears automatically (to prevent engine lug-
ging) during closed-throttle decelerations.
• The transmission will automatically down- shift to first gear when coming to a stop.
After a stop, the driver should manually
upshift (+) the transmission as the vehicle
is accelerated.
• You can start out, from a stop, in first or second gear. Tap (+) (at a stop) to select
second gear. Starting out in second gear
may be helpful in snowy or icy conditions.
• The system will ignore shift commands that would cause engine lugging or overspeed.
An audible beep will sound and a "Shift not
allowed" message will appear in the instru-
ment cluster if an inappropriate gear is
requested.
NOTE:
Avoid keeping your hand on the lever when
you are not requesting a gear shift.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer,
carrying a heavy load, etc., and frequent
transmission shifting occurs, press the TOW/
HAUL switch to activate TOW/HAUL mode.
This will improve performance and reduce
the potential for transmission overheating or
failure due to excessive shifting. When oper-
ating in TOW/HAUL mode, the transmission
shift calibration is modified to accommodate
steep grades in the smoothest possible man-
ner. TOW/HAUL mode is only applicable in
the DRIVE (D) position.
Parking The Vehicle
WARNING!
You or others could be injured if you leave
the vehicle unattended without fully ap-
plying the parking brake. The parking
brake should always be applied when the
driver is not in the vehicle.
To ensure proper parking performance, it is
essential to engage MANUAL (1st) gear,
DRIVE (D) or REVERSE (R) gear while your
foot is on the brake pedal. Once MANUAL
STARTING AND OPERATING
84

(1st) gear, DRIVE (D) or REVERSE (R) gear is
displayed in the instrument cluster display,
turn the engine off and engage the parking
brake. It is essential to wait until the gear
engaged appears in the display before turning
the engine off and releasing the brake pedal.
Always remember to apply your parking
brake.
NOTE:
NEVER leave your vehicle with the gearbox in
NEUTRAL (N) without the parking brake en-
gaged. Always remember to fully apply your
parking brake. Always remember to apply the
parking brake when the “Set Park Brake”
message is displayed.
General Warnings
• With the vehicle at a standstill and a gearengaged, keep the brake pedal pressed un-
til you decide to drive away. Then release
the brake and accelerate gradually. • When parked for long periods with the en-
gine running, it is advisable to place the
transmission in NEUTRAL (N) and apply
the parking brake.
• To avoid accelerated clutch wear, do not use the accelerator to keep the vehicle at a
standstill (for example, holding on a hill);
the clutch could be damaged by overheat-
ing. Use the brake pedal instead and oper-
ate the accelerator only when you are ready
to drive away.
• Only launch (from a stop) in second gear when you need more control on surfaces
with low traction.
• Only shift between DRIVE (D) and RE- VERSE (R) gears when the vehicle has
come to a stop and the brake pedal is
pressed. • Although very inadvisable, if the vehicle is
unexpectedly allowed to roll downhill with
the gearbox in NEUTRAL (N) the system
will automatically engage the gear best
suited to vehicle speed when a gear shift is
requested to allow drive to be correctly
transmitted to the wheels.
• If necessary, with the engine off, it is pos- sible to engage 1st, REVERSE (R) or NEU-
TRAL (N) with the key in ON/RUN/MAR
position and the brake pressed.
• During hill starts, accelerate immediately after releasing the parking brake or brake
pedal to allow the engine to increase its
rpm to a greater extent and overcome
higher gradients with more torque.

3. Disconnect the positive end(+)of the
jumper cable from the positive (+)post of
the booster battery.
4. Disconnect the opposite end of the posi- tive (+)jumper cable from the remote
positive (+)post of the discharged
vehicle.
5. Close the cover of the Front Power Distri- bution Center.
If frequent jump starting is required to start
your vehicle you should have the battery and
charging system inspected at your authorized
dealer.
CAUTION!
Accessories plugged into the vehicle
power outlets draw power from the vehi-
cle’s battery, even when not in use (i.e.,
cellular devices, etc.). Eventually, if
plugged in long enough without engine
operation, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
Battery Location
There are two remote jump starting posts
under the hood which is the recommended
jump start location. If access to the battery is
needed, an access panel on the driver’s side
floor will allow for battery access.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not in-
crease the engine idle speed while prevent-
ing vehicle motion with the brakes.
NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat. • You can also turn the temperature control
to maximum heat, the mode control to floor
and the blower control to high. This allows
the heater core to act as a supplement to
the radiator and aids in removing heat from
the engine cooling system.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator or coolant
bottle is hot.
