air conditioning CHRYSLER 300 M 2004 1.G Owners Manual

If the pointer rises to the “H” mark, stop the vehicle and
turn off the engine until the problem is corrected.
CAUTION!
Continuing to drive with an overheated engine cool-
ing system can cause damage to the engine or other
components.
There are steps that you can take to slow down an
impending overheat condition. If your air conditioning 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
the Fan 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.
16. Malfunction Indicator Light
This light is part of an onboard diagnostic
system called OBD that monitors engine and
automatic transmission control systems. Thelight will illuminate when the key is in the ON
position before engine start. If the bulb does not come
on when turning the key from OFF to ON, have the
condition checked promptly.
Certain conditions such as a loose or missing gas cap or
poor fuel quality may illuminate the light after engine
start. The vehicle should be serviced if the light stays on
through several of your typical driving cycles. In most
situations the vehicle will drive normally and will not
require towing.
The Malfunction Indicator Light flashes to alert to serious
conditions that could lead to immediate loss of power or
severe catalytic converter damage. The vehicle should be
serviced as soon as possible if this occurs.
17. Trip Odometer Reset Knob
To reset the trip odometer, push the reset knob for about
two seconds.
18. Airbag Light
The light will 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,

Fan Control
Use this control to regulate the amount of air forced
through the system in any mode you select. Turn the
control clockwise to increase fan speed.
In ambient temperatures below 70°F (21°C), fan opera-
tion is delayed when the engine is first started. The fan
will automatically start when the engine coolant is warm
enough to heat the air. This feature can be defeated by
turning the fan control.
AUTO Control
Press the top of the button to turn the ATC system On.
Press the lower portion of the button to turn the entire
system Off.
Comfort Control
Use this control to regulate the comfort inside the pas-
senger compartment. Press the top of the switch to raise
the temperature selection and the bottom of the switch to
lower it. The comfort setting range is from Lo, 60, 61,....to
89,90, Hi, for automatic temperature control. You can
select a very hot or cold comfort setting by holding the
comfort control until it reaches its highest or lowest
levels.The system adjusts to bring the interior temperature to
the desired comfort level. All comfort settings are auto-
matic; even Hi and Low.
NOTE:You can change the display from U.S. to metric
units by pressing the Mix and Panel mode buttons
simultaneously or by pressing the English/Metric button
on the overhead console.

NOTE:There is a varying difference in temperature
between the upper and lower outlets for added comfort.
The warmer air goes to the floor outlets. This feature
provides improved comfort during sunny but cool con-
ditions.
Windshield Defrost
Air is directed through the defrost outlets and
side window demist outlets. A small amount of
air also is directed through the floor outlets. Use this
mode with maximum fan and comfort level settings
for best windshield and side window defrosting. The
defrost symbol will glow in amber to show that the
defroster is on.
NOTE:
The air conditioning compressor is on in this
mode. This dehumidifies the air to help dry the wind-
shield. To improve fuel economy, leave in the defrost
mode only when necessary.
Rear Window Defroster
Press the button once to turn on the Rear Window
Defroster and a second time to turn it off. An
indicator light in the control shows that the defroster is
on.
NOTE:The defroster turns off automatically after 15
minutes of operation. Each later activation will allow 7
1/2 minutes of operation.
CAUTION!
To avoid damaging the electrical conductors, do not
use scrapers, sharp instruments, or abrasive window
cleaners on the interior surface of the rear window.
Labels can be peeled off by soaking with warm
water.
Window Fogging
In mild but rainy or humid weather, your windows may
fog up on the inside. You can remove this fog by pressing
the Defrost button. The Mix mode can be used to
maintain a clear windshield and provide sufficient heat-
ing. If side window fogging becomes a problem, increase
blower speed. The compressor will remain on during
these conditions.

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!
It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
negative post. Battery posts are marked positive (+)
and negative (-) and identified on the battery case.
Cable clamps should be tight on the terminal posts
and free of corrosion. Apply grease to posts and
clamps after tightening. If a “fast charger” is used
while the battery is in the vehicle, disconnect both
vehicle battery cables before connecting the charger
to battery. Do not use a “fast charger” to provide
starting voltage as battery damage can result.
Air Conditioner
Check the air conditioning system at the start of the
warm weather season.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser for an accumulation of dirt or insects. Clean with
a gentle water spray from behind the radiator andthrough the condenser as required. Fabric front fascia
protectors may reduce air flow to the condenser, reducing
air conditioning performance.
WARNING!
The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal injury
or damage to the system, adding refrigerant or any
repair requiring lines to be disconnected should be
done by an experienced repairman.
Refrigerant Recovery and Recycling
The air conditioning system of your vehicle contains
R-134a, a refrigerant that does not deplete the ozone layer
in the upper atmosphere, the manufacturer recommends
that air conditioning service be done by facilities using
refrigerant recyling and recovery equipment that meets
SAE standard J1991.

WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide which is colorless and odorless. Breathing
it can make you unconscious and can eventually
poison you. Follow the above precautions to keep
your exhaust system as safe as possible.
Cooling System
WARNING!
•When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition key
to the OFF position. The fan is controlled by
engine coolant temperature and Air Conditioning
pressure. It can start at any time the ignition key is
in the ON position.
•You or others can be badly burned by hot coolant
or steam from your radiator. If you see or hear
steam coming from under the hood, don’t open
the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
Coolant Checks
Check coolant protection every 12 months (before the
onset of freezing weather, where applicable). If the cool-
ant is dirty or rusty in appearance, the system should be
drained, flushed and refilled with fresh coolant.
214 MAINTAINING YOUR VEHICLE

•Maintain a coolant concentration of a minimum of 50%
ethylene glycol and high quality water with recom-
mended antifreeze for proper corrosion protection of
your engine cooling system that contains aluminum
components.
•Make sure that the radiator and coolant bottle hoses
are not kinked or obstructed.
•Keep the front of the radiator and air conditioning
condenser clean.
•Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine cooling performance,
poor gas mileage, and increased emissions.
Hoses and Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, checking, tears, cuts, abrasions,
and excessive swelling indicate deterioration of the rub-
ber.Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
Insure nylon tubing in these areas has not melted or
collapsed. Inspect all hose connections such as clamps
and couplings to make sure they are secure and no leaks
are present. Components should be replaced immedi-
ately if there is any evidence of degradation that could
cause failure.
Brakes
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in Section 8,
Maintenance Schedules.
