2009 CHRYSLER 300 SRT sensor

NOTE:Installing a vehicle front-end protector or an
aftermarket grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit ACC
operation.
ACC Unavailable Warning
If the system turns off, and the EVIC displaysACC
UNAVAILABLE,there may be a temporary malfunction
that limits ACC functionality. Although the vehicle is still
drivable under normal conditions, ACC will be tempo-
rarily unavailable. If this occurs, try activating ACC again
later, following a key cycle. If the problem persists, see
your authorized dealer.
Service ACC Warning
If the system turns off, and the EVIC displays “SERVICE
ACC,” it indicates there is an internal system fault.
Although the vehicle is still drivable under normal
conditions, have the system checked by an authorized
dealer.

The system uses four sensors located in the rear bumper
to scan for obstacles up to 59 in (150 cm) away from the
rear bumper fascia. The warning display located above
the rear window provides both visible and audible
warnings to indicate the range of the object.The warning display contains two sets of yellow and red
indicators, one set to warn of obstacles behind the left
rear of the vehicle and the other set to warn of obstacles
behind the right rear of the vehicle. The driver can view
the indicators either through the rearview mirror or by
looking at the display above the rear window.
The system dimly illuminates the two inner most yellow
indicators when it is on and detecting no obstacles. The
following chart shows the warning display operation
when the system is detecting an obstacle:

WARNING!
•Drivers must be careful when backing up even
when using the Rear Park Assist system. Always
check carefully behind your vehicle, look behind
you, and be sure to check for pedestrians, animals,
other vehicles, obstructions, and blind spots be-
fore backing up. You are responsible for safety and
must continue to pay attention to your surround-
ings. Failure to do so can result in serious injury or
death.
(Continued)
WARNING! (Continued)
•Before using the Rear Park Assist system, it is
strongly recommended that the ball mount and
hitch ball assembly is disconnected from the ve-
hicle when the vehicle is not used for towing.
Failure to do so can result in injury or damage to
vehicles or obstacles because the hitch ball will be
much closer to the obstacle than the rear fascia
when the warning display turns the red indicators
on. Also, the sensors could detect the ball mount
and hitch ball assembly, depending on its size and
shape, giving a false indication that an obstacle is
behind the vehicle.

CAUTION!
•The Rear Park Assist system is only a parking aid
and it is unable to recognize every obstacle, in-
cluding small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will not
be detected when they are in close proximity.
•The vehicle must be driven slowly when using the
Rear Park Assist system to be able to stop in time
when the obstacle is detected. It is recommended
that the driver look over their shoulder when
using the Rear Park Assist system.NOTE:
•Ensure that the rear bumper is free of dirt and debris
to keep the system operating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of the system.
If “Service Park Assist System” appears in the EVIC after
making sure the rear bumper is clean please see your
authorized dealer.

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
23. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned ON and remain on briefly
as a bulb check. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-essential
electrical devices or increase engine speed (if at idle). Ifthe charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
24. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD. The
OBD system monitors engine and automatic
transmission control systems. The MIL will turn on when
the key is in the ON position before engine start. If the
MIL does not come on when turning the key from LOCK
to ON, have the condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the MIL
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.

NOTE:Keep magnetic materials away from the top of
the instrument panel, such as iPod’s, Cell Phones, Lap-
tops and Radar Detectors. This is where the compass
module is located, and it can cause interference with the
compass sensor, and it may give false readings.
1. Turn the ignition switch ON.2. Press and hold the compass button for approximately
two seconds.
3. Press the FUNCTION SELECT button until “Compass
Variance” message, and the last variance zone number,
displays in the EVIC.
4. Press and release the FUNCTION SELECT button
until the proper variance zone is selected, according to
the map.
5. Press and release the compass button to exit.

Automatic Temperature Control
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 fromthe 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 into account
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 AUTO

NOTE:
•The surface of the climate control panel and the top
center of the instrument panel should be kept free of
debris due to the location of the climate control
sensors. Mud on the windshield may also cause poor
operation of this system.
•Extended use of recirculation may cause the windows
to fog. If the interior of the windows begin to fog, press
the recirculation button to return to outside air. Some
temp/humidity conditions will cause captured inte-
rior air to condense on windows and hamper visibility.
For this reason, the system will not allow recirculation
to be selected while in Defrost or Defrost/Floor mode.
Attempting to use the recirculation while in these
modes will cause the indicator in the control button to
blink and then turn off.
Manual Operation
This system offers a full complement of manual override
features, which consist of blower preferred automatic,
mode preferred automatic, or blower and mode preferred
automatic. This means the operator can override the
blower, the mode, or both. There is a manual blower
range for times when the AUTO setting is not desired.
The blower can be set to any fixed blower speed by
rotating the blower control knob (on the left).
NOTE:
•For vehicles equipped with Remote Start, the climate
controls will not function during Remote Start opera-
tion if the blower control is left in the “O” (Off)
position.
•Please read the Automatic Temperature Control Op-
eration Chart that follows for details.
