2012 CHRYSLER 300 SRT engine overheat

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
“260” 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 “260” and you hear continuous
chimes, turn the engine off immediately and call an
authorized dealership 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-
ship for service if your vehicle overheats. If you
decide to look under the hood yourself, see “Main-
taining Your Vehicle”. Follow the warnings under the
Cooling System Pressure Cap paragraph.

idle). If the charging system telltale remains on, it means
that the vehicle is experiencing a problem with the
charging system. Obtain SERVICE IMMEDIATELY. See
an authorized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.
•Electronic Throttle Control (ETC) TelltaleThis telltale informs you of a problem with the
Electronic Throttle Control (ETC) system. If the
telltale comes on while driving, have the sys-
tem checked by an authorized dealer.
If a problem is detected, the telltale 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 PARK position. The telltale should turn off. If the telltale remains lit with the engine running, your
vehicle will usually be drivable. However, see an autho-
rized dealer for service as soon as possible. If the telltale
is flashing when the engine is running, immediate service
is required. You may experience reduced performance, an
elevated/rough idle or engine stall and your vehicle may
require towing.•Engine Temperature Warning Telltale
This telltale warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,or260°F, this telltale will illuminate
and a single chime will sound after reaching a set
threshold. Further overheating will cause the tempera-
ture gauge to pass H,or260°F, a continuous chime will
occur until the engine is allowed to cool.

If the telltale 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 more information.
•Transmission Temperature Warning TelltaleThis telltale indicates that the transmission
fluid temperature is running hot. This may
occur with severe usage, such as trailer towing.
If this telltale turns on, safely pull over and
stop the vehicle. Then, shift the transmission into NEU-
TRAL and run the engine at idle or faster until the light
turns off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Telltale illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If the Transmission Temperature Warning Telltale is
illuminated and you continue operating the vehicle,
in some circumstances you could cause the fluid to
boil over, come in contact with hot engine or exhaust
components and cause a fire.
•Electric Power Steering Malfunction This telltale is on when the Electric Power
Steering is not operating and needs service.

Manual Operation
The system allows for manual selection of blower speed,
air distribution mode, A/C status and recirculation con-
trol.
The blower fan speed can be set to any fixed speed by
adjusting the blower control. The fan will now operate at
a fixed speed until additional speeds are selected. This
allows the front occupants to control the volume of air
circulated in the vehicle and cancel the Auto mode.
The operator can also select the direction of the airflow
by selecting one of the available mode settings. A/C
operation and Recirculation control can also be manually
selected in Manual operation.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
Use of the air Recirculation mode during Winter months
is not recommended because it may cause window
fogging.

Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
•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
service. 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 concentra-
tions of methanol. Fuel system damage or vehicle
performance problems resulting from the use of
such fuels or additives is not the responsibility of
the manufacturer.
NOTE: Intentional tampering with the emissions con-
trol system can result in civil penalties being assessed
against you.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located in the center
of the instrument panel between the center air outlets.
Press the switch to turn on the Hazard Warning
flashers. When the switch is activated, all direc-
tional 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 action.
•On the highways — slow down.
•In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase the 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.
428 WHAT TO DO IN EMERGENCIES

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 shift back and forth between DRIVE
and REVERSE. Using minimal accelerator pedal pressure
to maintain the rocking motion, without 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.
