2004 CHRYSLER 300 M ECU

The sunshade can be opened manually. It will also open
as the sun roof opens. The sunshade cannot be closed if
the sun roof is open.
WARNING!
In an accident, there is a greater risk of being thrown
from a vehicle with an open sun roof. You could also
be seriously injured or killed. Always fasten your
seatbelt properly and make sure all passengers are
properly secured too.
Do not allow small children to operate the sun roof.
Never allow fingers or other body parts, or any
object to project through the sun roof opening.
Injury may result.
Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter type sound in the
ears. Your vehicle may exhibit wind buffeting with the
windows down, or the sunroof (if so equipped) in certain
open or partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting occurs with
the rear windows open, open the front and rear windows
together to minimize the buffeting. If the buffeting occurs
with the sunroof open, adjust the sunroof opening to
minimize the buffeting.
Sun Roof Maintenance
Use only a non abrasive cleaner and a soft cloth to clean
the glass panel.

Transaxle Reset Mode
The transaxle is monitored for abnormal conditions. If a
condition is detected that could cause damage, the trans-
axle automatically shifts into second gear. The transaxle
remains in second gear despite the forward gear selected.
Park (P), Reverse (R), and Neutral (N) will continue to
operate. This Reset feature allows the vehicle to be driven
to a dealer for service without damaging the transaxle.
If the problem has been momentary, the transaxle can be
reset to regain all forward gears.
•Stop the vehicle and shift into PARK (P).
•Turn the key to OFF then start the engine.
•Shift into “D” and resume driving.
NOTE:Even if the transaxle can be reset, we recom-
mend that you visit a dealer at your earliest possible
convenience. Your dealer has diagnostic equipment to
determine if the problem could recur.
If the transaxle cannot be reset, dealer service is required.
Gear Ranges
“P” Park
NOTE:
If the key is in the RUN position, you must
press the brake pedal to shift out of the “P” Park position.
Supplements the parking brake by locking the transaxle.
Engine can be started in this range. Never attempt to use
PARK while vehicle is in motion.
Apply parking brake when leaving vehicle in this range.
“R” Reverse
Shift into this range only after the vehicle has come to a
complete stop.
“N” Neutral
The engine may be started in this range. Use this range
for starting your vehicle if it is moving or is being towed.
“D” Overdrive
This range should be used for most city and highway
driving. It provides smoothest up shifts and down shifts
and best fuel economy.
158 STARTING AND OPERATING

CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap). A poorly fitting cap
could let impurities into the fuel system. The Mal-
function Indicator light will come on if the gas cap is
not properly secured.
NOTE:The fuel tank filler tube has a restricting door
about 2 inches (50 mm) down from the opening. If fuel is
poured from a portable container, the container should
have a flexible nozzle long enough to force open the
restricting door.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE:
•
When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
•Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is properly
tightened.
The Malfunction Indicator light will come on if the gas
cap is not properly secured. Make sure that the gas cap
is tightened each time the vehicle is refueled.
WARNING!
•Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
•Never add fuel to the vehicle when the engine is
running.
•A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
178 STARTING AND OPERATING

•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.
218 MAINTAINING YOUR VEHICLE

WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
Brake and Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect surface of hoses for evidence of heat and me-
chanical damage. Hard and brittle rubber, cracking,
checking, tears, cuts, abrasion, and excessive swelling
suggest deterioration of the rubber. Particular attention
should be made to examining those hose surfaces nearest
to high heat sources, such as the exhaust manifold.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE:Often, fluids such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to ease the assembly of hoses to couplings. There-
fore, oil wetness at the hose-coupling area is not neces-
sarily an indication of leakage. Actual dripping of hot
fluid when systems are under pressure (during vehicle
operation) should be noted before hose is replaced based
on leakage.
NOTE:Inspection of brake hoses should be done
whenever the brake system is serviced and every engine
oil change.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Master CylinderThe fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning lamp shows system failure.
