2015 Ram 2500 overheating

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 clutch or 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” in “Starting And Operating” for further infor-
mation. 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/2nd gear and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drive-
train 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).

WHAT TO DO IN EMERGENCIES 731

CAUTION!(Continued)
•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 converter
will not require maintenance. However, it is important 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.
To minimize the possibility of catalytic converter dam-
age:
•
Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
