2018 Ram ProMaster City overheating

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 but-
ton a second time to turn off the Recircula-
tion 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. OAT coolant
(conforming to MS.90032) is recommended.
Refer to “Dealer Service” in “Servicing And
Maintenance” in your Owner’s Manual at
www.mopar.com/en-us/care/owners-manual.html
(U.S. Residents) or www.owners.mopar.ca
(Canadian Residents) for proper coolant se-
lection.
Winter Operation
To ensure the best possible heater and de-
froster performance, make sure the engine
cooling system is functioning properly and
the proper amount, type, and concentration
of coolant is used. Refer to “Dealer Service”
in “Servicing And Maintenance” in your Own-
er’s Manual at
www.mopar.com/en-us/
care/owners-manual.html
(U.S. Residents) or
www.owners.mopar.ca (Canadian Residents)
for proper coolant selection. Use of the air
Recirculation mode during Winter months is
not recommended because it may cause win-
dow 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 fresh air with the
blower setting on high. This will ensure ad-
equate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
GETTING TO KNOW YOUR VEHICLE

6. The vehicle may then be started inNEUTRAL.
7. Reinstall the gear selector boot.
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.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (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 HOT (H), and you hear
CAUTION!
continuous chimes, turn the engine off
immediately and call for service.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand,
or snow, it can often be moved using a rock-
ing motion. Turn the steering wheel right and
left to clear the area around the front wheels.
Push and hold the lock button on the gear
selector. Then shift back and forth between
DRIVE and REVERSE, while gently pressing
the accelerator. Use the least amount of ac-
celerator pedal pressure that will maintain
the rocking motion, without spinning the
wheels or racing the engine.
NOTE:
Shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL for more than two sec-
onds, you must press the brake pedal to
engage DRIVE or REVERSE.
IN CASE OF EMERGENCY
106

CAUTION!
Racing the engine or spinning the wheels
may lead to transmission overheating and
failure. Allow the engine to idle with the
transmission in NEUTRAL for at least one
minute after every five rocking-motion
cycles. This will minimize overheating and
reduce the risk of transmission failure dur-
ing prolonged efforts to free a stuck ve-
hicle.
NOTE:
Push the "ESC Off" switch, to place the Elec-
tronic Stability Control (ESC) system in "Par-
tial Off" mode, before rocking the vehicle.
Refer to “Electronic Brake Control System”
in “Safety” in the Owner’s Manual at
www.mopar.com/en-us/care/owners-manual.html
(U.S. Residents) or www.owners.mopar.ca
(Canadian Residents) for further information.
Once the vehicle has been freed, push the
"ESC Off" switch again to restore "ESC On"
mode.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode
and injure someone. Do not spin your ve-
hicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
• When “rocking” a stuck vehicle by shift- ing between DRIVE and REVERSE, do
not spin the wheels faster than 15 mph
(24 km/h), or drivetrain damage may
result.
• Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
107

WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your stop-
ping distance. Use tires of the recom-
mended load capacity for your vehicle.
Never overload them.
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride ComfortSafety
WARNING!
• Improperly inflated tires are dangerous
and can cause collisions.
• Underinflation increases tire flexing and
can result in overheating and tire failure.
• Overinflation reduces a tire's ability to cushion shock. Objects on the road and
chuckholes can cause damage that re-
sult in tire failure.
• Overinflated or underinflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle control.
• Unequal tire pressures can cause steer-
ing problems. You could lose control of
your vehicle.
• Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
• Always drive with each tire inflated to
the recommended cold tire inflation
pressure. Both under-inflation and over-inflation affect
the stability of the vehicle and can produce a
feeling of sluggish response or over respon-
siveness in the steering.
NOTE:
• Unequal tire pressures from side to side
may cause erratic and unpredictable steer-
ing response.
• Unequal tire pressure from side to side may cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consump-
tion.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and reduced
tread life, resulting in the need for earlier tire
replacement.
