2012 Ram Cargo Van engine overheat

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located in the
lower center area of the instrument panel.Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming
traffic of an emergency. Press 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 ac-
tion.
•On the highways — slow down.
•In city traffic — while stopped, place the transmission
in NEUTRAL, but do not increase engine idle speed.
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.

8. Disconnect the opposite end of the positive(+)jumper
cable from the positive (+)post of the booster battery.
9. Disconnect the positive (+)end of the jumper cable
from the positive (+)post of the discharged vehicle.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!
Accessories that can be plugged into the vehicle
power outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then move the shift lever back and forth
between DRIVE and REVERSE. Using minimal accelera-
tor pedal pressure to maintain the rocking motion, with-
out spinning the wheels, is most effective.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the shift lever 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.
536 WHAT TO DO IN EMERGENCIES

NOTE:To improve the vehicle’s traction when starting
off in deep snow, sand or gravel, it may be desirable to
switch the Electronic Stability Program (ESP) to “Partial
Off” mode. Refer to “Electronic Brake Control System” in
“Starting and Operating” for further information.
CAUTION!
•When “rocking” a stuck vehicle by moving 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
transmission shifting occurring).
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated 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 vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck and do not let anyone near
a spinning wheel, no matter what the speed.
SHIFT LEVER OVERRIDE
If a malfunction occurs and the shift lever cannot be
moved out of the PARK position, you can use the
following procedure to temporarily move the shift lever:
1. Firmly apply the parking brake.

CAUTION!
•The catalytic converter requires the use of un-
leaded fuel only. Leaded gasoline will destroy the
effectiveness of the catalyst as an emissions con-
trol device and may seriously reduce engine per-
formance 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.

Cooling System Pressure Cap
The cap must be fully tightened to prevent the loss of
engine coolant (antifreeze), and to ensure that engine
coolant (antifreeze) will return to the radiator from the
coolant recovery bottle.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
•The warning words “DO NOT OPEN HOT” on the
cooling system pressure cap are a safety precaution.
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 pres-
sure cap while the system is hot or under pressure.
(Continued)
WARNING! (Continued)
•Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.
Disposal Of Used Coolant
Used ethylene glycol-based engine coolant (antifreeze) is
a regulated substance requiring proper disposal. Check
with your local authorities to determine the disposal
rules for your community. To prevent ingestion by ani-
mals or children, do not store ethylene glycol-based
engine coolant (antifreeze) in open containers or allow it
to remain in puddles on the ground. If ingested by a child
or pet, seek emergency assistance immediately. Clean up
any ground spills immediately.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
