engine overheat Ram ProMaster 2015 Owner's Manual

WARNING!(Continued)
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.
17. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. 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” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized 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

WARNING!(Continued)
Vehicle.” Follow the warnings under the “Cooling
System Pressure Cap” paragraph.
18. Engine Temperature Warning Light
This light warns of an overheated engine condition. As
engine coolant temperatures rise and the gauge ap-
proaches H, this indicator will illuminate, and a single
chime will sound after reaching a set threshold.
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 ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for further information. 19. Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped and the
shift lever is placed in the NEUTRAL position, and apply
the parking brake. The light should turn off. If the light
remains lit with the engine running, your vehicle will
usually be drivable. However, see an authorized dealer
for service as soon as possible. If the light is flashing
when the engine is running, immediate service is re-
quired, and you may experience reduced performance,
an elevated/rough idle, or engine stall; your vehicle may
require towing. The light will come on when the ignition
is first turned to ON/RUN and remain on briefly as a
bulb check. If the light does not come on during starting,
have the system checked by an authorized dealer.

When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, push 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 operating in TOW/HAUL
mode, transmission upshifts are delayed, and the trans-
mission will automatically downshift (for engine brak-
ing) during steady braking maneuvers.
The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate that TOW/HAUL mode
has been activated. Pushing the switch a second time
restores normal operation. Normal operation is always
the default at engine start-up. If TOW/HAUL mode is
desired, the switch must be pushed each time the engine
is started.Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
some accelerations, the clutch automatically disengages.
NOTE:
•
The torque converter clutch will not engage, until the
transmission fluid and engine coolant are warm [usu-
ally after 1 to 3 miles (2 to 5 km) of driving]. Because
the engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into Overdrive when cold. This is
normal. Using the Electronic Range Select (ERS) shift
control, when the transmission is sufficiently warm,
will demonstrate that the transmission is able to shift
into and out of Overdrive.

Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine per-
formance and damage the emissions control sys-
tem.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate ser-
vice. Contact your authorized dealer for service
assistance.
(Continued)
CAUTION! (Continued)
•The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentrations
of methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
NOTE: Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
instrument panel below the climate controls.Push the switch to turn on the Hazard Warning
flasher. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncoming
traffic of an emergency. Push the switch a second time to
turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use the Hazard Warning flashers
may wear down your battery.
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 increase the engine idle
speed while maintaining the motion of the vehicle
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.

WHAT TO DO IN EMERGENCIES 287

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it
can often be moved using a rocking motion. Turn the
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE
and REVERSE , while gently pressing the accelerator. Use
the least amount of accelerator pedal pressure that will
maintain the rocking motion, without spinning the
wheels or racing the engine.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine 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 during prolonged
efforts to free a stuck vehicle.NOTE:
Push the ESC Off switch, to place the Electronic
Stability Control (ESC) system in Partial Offmode,
before rocking the vehicle. Refer to “Electronic Brake
Control System” in “Starting And Operating” for further
information. Once the vehicle has been freed, push the
ESC Off switch again to restore ESC Onmode.
CAUTION!
•When “rocking” a stuck vehicle by shifting be-
tween 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 damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no trans-
mission shifting occurring).6
WHAT TO DO IN EMERGENCIES 323

CAUTION!
•The catalytic converter requires the use of un-
leaded fuel only. Leaded gasoline will destroy the
effectiveness of the catalyst as an emissions control
device and may seriously reduce engine perfor-
mance and cause serious damage to the engine.
• Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition.
In the event of engine malfunction, particularly
involving engine misfire or other apparent loss of
performance, have your vehicle serviced promptly.
Continued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle. Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
NOTE:
Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufacturer’s specifica-
tions, should be obtained immediately.

MAINTAINING YOUR VEHICLE 339

NOTE:
•Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system please contact your
local authorized dealer.
• Mixing engine coolant (antifreeze) types is not recom-
mended and can result in cooling system damage. If
HOAT and OAT coolant are mixed in an emergency,
have a authorized dealer drain, flush, and refill with
OAT coolant (conforming to MS.90032) as soon as
possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that engine coolant
(antifreeze) will return to the radiator from the coolant
recovery tank. The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
•
Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is
overheated. Do not loosen or remove the cap to cool
an overheated engine. Heat causes pressure to
build up in the cooling system. To prevent scalding
or injury, do not remove the pressure cap while the
system is hot or under pressure.
• Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.
