ECO mode CHRYSLER 300 C 2008 1.G Service Manual

Mode Control
The rotary knob on the right controls
airflow distribution. Dots between
each of the mode selections identify
intermediate modes that allow the op-
erator to fine-tune airflow distribu-
tion. The mode settings are as follows:
•Defrost
Air is directed to the windshield through the
outlets at the base of the windshield. Air is also
directed to the front door windows through the side
window demister grilles.
NOTE:To improve fuel economy, leave in defrost only
when necessary.
•Defrost/Floor
Air flows through the front and rear floor outlets
and the outlets at the base of the windshield. Airis also directed to the front door windows through the
side window demister grilles.
•Floor
Air flows through the floor outlets located under
the instrument panel and into the rear seating
area through vents under the front seats.
•Bi-Level
Air flows through the outlets located in the
instrument panel and through the outlets located
on the floor. Air flows through the registers in the back
of the center console to the rear seat passengers. These
registers can be closed to partially block airflow.
•Panel
Air flows through the outlets located in the in-
strument panel. Air flows through the registers in
the back of the center console to the rear seat passen-
gers. These registers can be closed to block airflow.

•Recirculation Control
The mode control knob also controls the
recirculation feature. You can choose Bi-
Level Recirculation air outlets, Panel Recir-
culation air outlets, or a mix or both while in
this mode. Normally, air enters from outside the
vehicle. However, when in Recirculation mode air
inside the vehicle is re-used. Use this mode to cool the
inside of the vehicle rapidly. The Recirculation mode
can also be used to temporarily block out outside
odors, smoke, and dust.
Air Conditioning Control
Press this button to turn on and turn off the air
conditioning. When the air conditioning is turned
on, cool dehumidified air will flow through the
outlets selected with the mode control. Press this button
a second time to turn off the air conditioning. An LED in
the button will illuminate when compressor operation is
selected.
Automatic Temperature Control — If Equipped
Automatic Operation
The Infrared Dual-Zone Climate Control System auto-
matically maintains the climate in the cabin of the vehicle
at the comfort levels desired by the driver and passenger.
To accomplish this, the system gathers information from
Automatic Temperature Controls
284 UNDERSTANDING YOUR INSTRUMENT PANEL

the controls on the climate control, from a dual sun-
sensor located in the top of the instrument panel, from an
infrared sensor located in the face of the climate control,
and from various sensors located throughout the vehicle.
The controls on the climate control provide the system
with operator input. The dual sun-sensor monitors sun
load coming through the windshield. The infrared sensor
independently measures the surface temperature of the
driver and passenger. Other sensors take account of
vehicle-speed, A/C pressure, outside temperature, and
engine cooling temperature. Using all of these inputs, the
system automatically adjusts airflow temperature, air-
flow distribution, airflow volume, and the amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.
Operation of the system is quite simple. Begin by turning
the Mode Control knob (on the right) to AUTO, and place
the Blower Control knob (on the left) to either LO AUTOor HI AUTO. The LO AUTO position should be used for
front seat occupants only. The HI AUTO position should
be used when more airflow is desired, or when rear seat
occupants are present. Then, dial in the temperature you
would like the system to maintain by rotating the driver
or passenger Temperature Control knob. Once the com-
fort level is selected, the system will maintain that level
automatically using the heating system. Should the de-
sired comfort level require air conditioning, the system
will automatically make the adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the OFF position on the fan control stops the system
completely and closes the outside air intake.
72°F (22°C) is the recommended setting for maximum
comfort for the average person; however, this may vary.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic operation.

The operator can override the AUTO mode setting to
change airflow distribution by rotating the Mode Control
knob (on the right) to one of the following positions.
•Defrost
Air is directed to the windshield through the
outlets at the base of the windshield. Air is also
directed to the front door windows through the side
window demister grilles.
•Defrost/Floor
Air flows through the front and rear floor outlets
and the outlets at the base of the windshield. Air
is also directed to the front door windows
through the side window demister grilles.
•Floor
Air flows through the floor outlets located under
the instrument panel and into the rear seating
area through vents under the front seats.
•Bi-Level
Air flows through the outlets located in the
instrument panel and through the outlets located
on the floor. Air flows through the registers in the back
of the center console to the rear seat passengers. These
registers can be closed to block airflow.
•Panel
Air flows through the outlets located in the in-
strument panel. Air flows through the registers in
the back of the center console to the rear seat passen-
gers. These registers can be closed to block airflow.
•Air Conditioning Control
Press this button to turn on the air conditioning
during manual operation only. When the air
conditioning is turned on, cool dehumidified
air will flow through the outlets selected with the
Mode control dial. Press this button a second time to
UNDERSTANDING YOUR INSTRUMENT PANEL 289

turn off the air conditioning. An LED in the button
illuminates when manual compressor operation is
selected.
NOTE:To control the air conditioning manually, the
mode selector must be moved out of the AUTO position.
•Recirculation Control
This button can be used to block out smoke,
odors, dust, high humidity, or if rapid cooling
is desired. The recirculation mode should only
be used temporarily. An LED in the button
illuminates when the recirculation mode is active. You
may use this feature separately.
NOTE:Extended use of recirculation may cause the
windows to fog. If the interior of the windows begins to
fog, press the Recirculation button to return to outside
air. Some temp/humidity conditions will cause capturedinterior air to condense on windows and hamper visibil-
ity. For this reason, the system will not allow Recircula-
tion to be selected while in defrost or defrost/floor mode.
Attempting to use the recirculation while in these modes
will cause the LED in the control button to blink and then
turn off.Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
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 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to “Maintenance Procedures” in Section 7 of this manual
for proper coolant selection.

Winter Operation
Use of the air Recirculation mode during winter months is
not recommended because it may cause window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
winter months, make sure the air intake is clear of ice,
slush, and snow.
A/C Air Filter — If Equipped
The climate control system filters outside air containing
dust, pollen and some odors. Strong odors cannot be
totally filtered out. Refer to “Maintenance Procedures” in
Section 7 of this manual for filter replacement instruc-
tions.

Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could cause damage, the
transmission automatically shifts into second gear. The
transmission remains in second gear despite the forward
gear selected. “P” (Park), “R” (Reverse), and “N” (Neu-
tral) will continue to operate. This Reset feature allows
the vehicle to be driven to a dealer for service without
damaging the transmission.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
•Stop the vehicle and shift into “P” (Park).
•Turn the key to LOCK then start the engine.
•Shift into “D” (Drive) and resume driving.NOTE:Even if the transmission 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 transmission cannot be reset, dealer service is
required.
5 Speed Automatic Transmission
Shifting from “D” (Drive) to “P” (Park) or “R” (Reverse)
(or from “P” or “R” to “D”) should be done only after the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake when moving the
selector lever between these gears.
312 STARTING AND OPERATING

CAUTION!
Coasting the vehicle or driving for any other reason
with selector lever in NEUTRAL can result in trans-
mission damage.
WARNING!
Do not coast in “N” (Neutral) and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have an accident.“D” (Drive)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts and the best fuel economy.
The transmission automatically upshifts through fifth
gear. The “D” (Drive) position provides optimum driving
characteristics under all normal operating conditions.
When frequent transmission shifting occurs when using
the Overdrive range, such as when operating the vehicle
under heavy loading conditions (in hilly terrain, travel-
ing into strong head winds, or while towing heavy
trailers, use the AutoStick\2mode and select the “3”
range.
AutoStick\2Gear selection
The AutoStick\2feature can be selected by pressing the
selector lever to the right or the left with the lever in the
“D” (Drive) position. The gear currently selected is
indicated in the instrument cluster display. Briefly, press

damage, the transmission will engage Limp Home Mode.
If vehicle acceleration worsens, or the transmission no
longer shifts, the transmission is most likely operating in
the Limp Home Mode. In this mode, the transmission
will remain in the current gear until the vehicle is
brought to a stop. After the vehicle has stopped, “P”
(Park), “R” (Reverse), and “N” (Neutral) will continue to
operate. Second gear will operate in the “D” (Drive)
shifter position. The Malfunction Indicator Light may be
illuminated.
A reset feature is available to allow the vehicle to be
driven to a dealer for service. To reset the transmission,
use the following procedure:
1. Stop the vehicle.
2. Move the selector lever to the “P” (Park) position.
3. Turn off the engine.
4. Wait approximately 10 seconds.5. Restart the engine.
6. Move the selector lever to the desired range. If the
problem is no longer detected, the transmission will
return to normal operation.
NOTE:Even if the transmission 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.
Have the transmission checked at your authorized dealer
as soon as possible.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
Permanent Transmission Limp Home Mode
Permanent Limp Home Mode will be activated if the
transmission enters temporary Limp Home Mode three
times. Follow the reset procedure described under “Tem-
porary Transmission Limp Home Mode” in this section.
