Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Controller (ORC)
•AIRBAG Readiness Light
•Driver Airbag
•Passenger Airbag (if equipped)
•Steering Wheel and Column
•Instrument Panel
•Crash Sensor
•Interconnecting Wiring
•Knee Impact Bolsters
•Passenger’s Side Front Airbag ON/OFF Switch (Regu-
lar Cab Vehicles Only ) (if equipped)
How The Airbag System Works
•
The Occupant Restraint Controller (ORC) determines
if a frontal collision is severe enough to require the
airbags to inflate.
•The ORC will not detect rollover, or rear collisions.
•The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or RUN positions. These include all of the
items listed above except the knee bolsters, the instru-
ment panel, and the steering wheel and column. If the
key is in the OFF position, in the ACC position, or not
in the ignition, the airbags are not on and will not
inflate.
•The ORC also turns on the Airbag Warning Light in
the instrument panel for 6 to 8 seconds when the
ignition is first turned on, and then turns the light off.

NOTE:
•A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually in-
dicative of a crash, but not severe enough to warrant
airbag deployment.
•Under certain circumstances, EDR data may not be
recorded (e.g., loss of battery power).
In conjunction with other data gathered during a com-
plete accident investigation, the electronic data may be
used by Chrysler LLC and others to learn more about the
possible causes of crashes and associated injuries in order
to assess and improve vehicle performance. In addition
to crash investigations initiated by Chrysler LLC, such
investigations may be requested by customers, insurance
carriers, government officials, and professional crash
researchers, such as those associated with universities,
and with hospital and insurance organizations. In the event that an investigation is undertaken by
Chrysler LLC (regardless of initiative), the company or its
designated representative will first obtain permission of
the appropriate custodial entity for the vehicle (usually
the vehicle owner or lessee) before accessing the elec-
tronic data stored, unless ordered to download data by a
court with legal jurisdiction (i.e., pursuant to a warrant).
A copy of the data will be provided to the custodial entity
upon request. General data that does not identify par-
ticular vehicles or crashes may be released for incorpo-
ration in aggregate crash databases, such as those main-
tained by the US government and various states. Data of
a potentially sensitive nature, such as would identify a
particular driver, vehicle, or crash, will be treated confi-
dentially. Confidential data will not be disclosed by
Chrysler LLC to any third party except when:
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Compass Varianceis the difference between magnetic
North and geographic North. In some areas of the
country, the difference between magnetic and geographic
North is great enough to cause the compass to give false
readings. If this occurs, the compass variance must be set
according to the Compass Variance Map. NOTE:
The default for the compass variance is Zone 8.
To set the variance: Turn the ignition ON and set the
display to “Compass/Temperature.” Press and hold the
RESET button approximately five seconds. The last vari-
ance zone number will be displayed. Press the STEP
button to select the new variance zone and press the
RESET button to resume normal operation.
Outside Temperature
Because the ambient temperature sensor is located un-
derhood, engine temperature can influence the displayed
temperature. Therefore, temperature readings are slowly
updated when the vehicle speed is below 20 mph
(30 km/h) or during stop-and-go driving.

Over the Road Operation With Snowplow
Attached
The blade restricts air flow to the radiator and causes the
engine to operate at higher than normal temperatures.
Therefore, when transporting the plow, angle the blade
completely and position it as low as road or surface
conditions permit. Do not exceed 40 mph (64 km/h). The
operator should always maintain a safe stopping distance
and allow adequate passing clearance.
Operating Tips
Under ideal snow plowing conditions, 20 mph (32 km/h)
should be maximum operating speed. The operator
should be familiar with the area and surface to be
cleaned. Reduce speed and use extreme caution when
plowing unfamiliar areas or under poor visibility.
NOTE:During snowplow usage on vehicles equipped
with an overhead console module, the outside tempera-
ture display will show higher temperatures than the outside ambient temperature. The higher displayed tem-
perature is due to blocked or reduced airflow to the
underhood ambient temperature sensor by the snow-
plow. This is common and outside temperature display
operation will return to normal when the snowplow is
removed.
General Maintenance
Snowplows should be maintained in accordance with the
plow manufacturer’s instructions.
Keep all snowplow electrical connections and battery
terminals clean and free of corrosion.
When plowing snow, to avoid transmission and drive-
train damage, the following precautions should be ob-
served.
