2004 CHRYSLER 300 M overheating

Autostick General Information
•
The transmission will automatically upshift from first
to second gear and from second to third gear when
engine speed reaches about 6300 rpm.
•Downshifts from third to second gear above 85 mph
(137 km/h) and from second to first gear above 47
mph (76 km/h) will be ignored.
•You can start out in first, second, or third gear. Shifting
into fourth gear can occur only after vehicle speed
reaches 17 mph (27 km/h).
•The transmission will automatically downshift to first
gear when coming to a stop.
•Starting out in second or third gear is helpful in snowy
or icy conditions.
•While in the Autostick mode, Speed Control will only
function in third or fourth gear.
Downshifting out of third gear turns off speed control.
•If the system detects powertrain overheating, the
transmission will revert to the automatic shift mode
and remain in that mode until the powertrain cools off.
•If the system detects a problem it will disable the
Autostick mode and the transmission will return to the
automatic mode until the problem is corrected.
•The transmission will automatically downshift from
fourth to third gear at speeds between 15 mph (24
km/h and 50 mph (80 km/h) under certain conditions.
This is to avoid poor fourth gear performance with
accelerator pedal actuation at lower speeds.
160 STARTING AND OPERATING

•The system has been deactivated to prevent damage to
the brake system due to overheated brake tempera-
tures.
NOTE:Extended heavy use of Traction Control may
cause the system to deactivate and turn on the Traction
Control OFF Light, indicated byTRAC OFF, located in
the instrument cluster.
This is to prevent overheating of the brake system and is
a normal condition. After cooling, the system will auto-
matically reactivate and turn off theTRAC OFFlight.
If your vehicle becomes stuck in mud, ice, or snow, turn
the Traction Control System Off before attempting to
“rock” the vehicle free.
TIRES
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:
1. Safety—
WARNING!
•Improperly inflated tires are dangerous and can
cause accidents.
•Under inflation increases tire flexing and can
result in tire failure.
•Over inflation reduces a tire’s ability to cushion
shock. Objects on the road and chuck holes can cause
damage that results in tire failure.
•Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
•Overinflated or under inflated tires can affect
vehicle handling and can fail suddenly, resulting in
loss of vehicle control.
•Always drive with each tire inflated to the recom-
mended pressure.
164 STARTING AND OPERATING

adequate performance. For Example, choose “4” if the
desired speed can be maintained. Choose “3” or “2” if
needed to maintain the desired speed.
Extended driving at high RPM’s should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be necessary to avoid extended driving at
high RPMs. Return to a higher gear range or vehicle
speed when road conditions and RPM level allow.
•
The trailer tongue load must be considered as part of
the tow vehicle load capacity when loading the ve-
hicle.
•If the trailer weighs more than 1,000 lbs. (450 kg), it
should have its own brakes.
WARNING!
Connecting trailer brakes to your vehicle’s hydraulic
brake lines can overload your brake system and
cause it to fail. You might not have brakes when you
need them and could have an accident.
•Whenever you pull a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
recommended for motoring safety.
•The automatic transmission fluid, filter, and hypoid
differential fluid should be changed per Maintenance
Schedule “B” if you tow a trailer.
•If your Engine Coolant Light comes on, see the para-
graph on Overheating in Section 6 of this manual.
NOTE:Check the automatic transmission fluid level
before all towing. Fluid discoloration, or a burnt odor,
shows the need for a transmission fluid and filter change.
180 STARTING AND OPERATING

HAZARD WARNING FLASHER
The flasher switch is on the steering column, just
behind the steering wheel. Push in the flasher
switch and all front and rear directional signals
will flash. Press the flasher switch a second time to turn
the flashers off.
Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed and the vehicle locked.
NOTE:With extended use, the flasher may run 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, put transaxle 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
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
182 WHAT TO DO IN EMERGENCIES

CAUTION!
Racing 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).
TOWING A DISABLED VEHICLE
Only two ways of towing are approved; front towing and
flat bed towing.
CAUTION!
•Do not attempt to tow this vehicle from the front
with sling type towing equipment. Damage to the
front fascia will result.
•Always use wheel lift equipment when towing
from the front. The only other approved method
of towing is with a flat bed truck.
•Do not tow the vehicle from the rear. Damage to
the rear sheet metal and fascia will occur.
•Do not push or tow this vehicle with another
vehicle as damage to the bumper fascia and trans-
axle may result.
If damage to the vehicle prevents towing from the front,
move the vehicle onto a flat bed tow truck.

CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
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 catalyst damage:
•Do not shut off the engine or interrupt the ignition
when the transaxle is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
Engine Timing Belt
Replace the engine timing belt at the intervals described
in the appropriate maintenance schedule.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from sticking or plugging due to deposits. As vehicle
mileage builds up, the PCV valve and passages may
accumulate deposits. If a valve is not working properly,

Check the front of the radiator and condenser for any
accumulation of bugs, leaves, etc. Clean the radiator and
condenser by gently spraying water from a garden hose
at the back of the core.
Check the engine cooling system hoses for condition and
tightness of connection. Inspect the entire system for
leaks. Any hoses that show cuts or severe abrasion must
be replaced.
Cooling System — Drain, Flush and Refill
At the intervals shown on the Maintenance Schedules (5
years/100,000 miles), the system should be drained,
flushed and refilled.
If the solution is dirty and contains a considerable
amount of sediment, clean and flush with a reliable
cooling system cleaner. Follow with a thorough rinsing to
remove all deposits and chemicals.
Engine Coolant Disposal
Used ethylene glycol based engine coolant is a regulated
substance requiring proper disposal. Check with your
local authorities to determine the disposal rules for your
community. Do not store ethylene glycol based enginecoolant in open containers or allow it to remain in
puddles on the ground. Prevent ingestion by animals or
children. If ingested by a child, contact a physician
immediately.
Selection Of Coolant
Use only the manufacturer’s recommended coolant. Re-
fer to the Recommended Fluids, Lubricants and Genuine
Parts section for correct coolant type.
CAUTION!
Failure to use the proper antifreeze could cause
radiator plugging and engine overheating. Do not
mix antifreeze brands or types. Do not use plain
water alone or alcohol base antifreeze products. Do
not use additional rust inhibitors or antirust prod-
ucts, as they may not be compatible with the radiator
coolant and may plug the radiator.
Adding Coolant
When adding coolant, a minimum solution of 50% eth-
ylene glycol antifreeze coolant in water should be used.
