2004 CHRYSLER 300 M heating

ENGINE BREAK-IN RECOMMENDATIONS
The engine in your new vehicle does not require a long
break-in period.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or 55
mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration, within the
limits of local traffic laws, contributes to a good break-in.
Wide open throttle acceleration in low gear can be
detrimental and should be avoided.
The crankcase oil installed in the engine at the factory is
a high quality energy conserving type lubricant. Oil
changes should be consistent with expected climate con-
ditions under which vehicle operations will occur. The
recommended viscosity and quality grades are in Section
7 of this manual.
Do not use non-detergent or straight mineral oils.
A new engine may consume some oil during its first few
thousand miles of operation. This is a normal part of the
break-in and not an indication of a problem.
SAFETY TIPS
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
•Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in
or out of the area.
•If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling con-
trols to force outside air into the vehicle. Set the blower
at high speed.
•To avoid drawing exhaust gases into the vehicle, close
the trunk while driving. However, if for some reason it

must remain open, close all windows. Adjust the
heating or cooling system to force outside air into the
vehicle. Set the blower at high speed.
Safety Checks You Should Make Inside the
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Safety belt assemblies must be replaced after an accident
if they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding belt or retractor
condition, replace the belt.
Airbag Light
The light should come on and remain on for 6 to
8 seconds as a bulb check when the ignition
switch is first turned ON. If the bulb is not lit
during starting, have it replaced. If the light stays on or
comes on while driving, have the system checked by an
authorized dealer.
Defrosters
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield.
Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect for tread cuts or sidewall
cracks. Check wheel nuts for tightness and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for
brake fluid, fuel, water, oil, or other fluid leaks. Also, if
gasoline fumes are present, the cause should be corrected
immediately.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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,
