QUIRED message appears in the instrument cluster dis-

Cleaning The ParkSense System
Clean the ParkSense sensors with water, car wash soap and
a soft cloth. Do not use rough or hard cloths. Do not scratch
or poke the sensors. Otherwise, you could damage the
sensors.
ParkSense System Usage Precautions
NOTE:
• Ensure that the front and rear bumper are free of snow,
ice, mud, dirt and debris to keep the ParkSense system
operating properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
• When you turn ParkSense off, the instrument cluster
will display “PARKSENSE OFF.” Furthermore, once you
turn ParkSense off, it remains off until you turn it on
again, even if you cycle the ignition. •
When you move the gear selector to the REVERSE
position and ParkSense is turned off, the instrument
cluster will display “PARKSENSE OFF” for as long as
the vehicle is in REVERSE.
• ParkSense, when on, will reduce the volume of the radio
when it is sounding a tone.
• Clean the ParkSense sensors regularly, taking care not to
scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense system might not detect an
obstacle behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle is
behind or in front of the fascia/bumper.
• Use the ParkSense switch to turn the ParkSense system
off if objects such as bicycle carriers, trailer hitches, etc.
are placed within 12 inches (30 cm) from the rear
fascia/bumper. Failure to do so can result in the system
misinterpreting a close object as a sensor problem,
causing the “PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message to be displayed in the instrument
cluster.
338 STARTING AND OPERATING

•Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts.
• After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a wheel
imbalance and freeing the wheels of it will correct the
situation.

NOTE:
•Your vehicle may be transmitting data as authorized by
the subscriber.
• The 9–1–1 and ASSIST buttons will only function if you
are connected to an operable 1X(voice/data) or 3G(data)
network. Other Uconnect services will only be operable
if your Uconnect Access service is active and you are
connected to an operable 1X(voice/data) or 3G(data)
network.

4. You should be able to speak with the 9-1-1 operatorthrough the vehicle audio system to determine if addi-
tional help is needed.
WARNING!
ALWAYS obey traffic laws and pay attention to the
road. Some Uconnect Access services, including 9-1-1
and Assist, will NOT work without an operable
1X(voice/data) or 3G(data) network connection.
NOTE: •Your vehicle may be transmitting data as authorized
by the subscriber.
• Once a connection is made between the vehicle’s 9-1-1
Call system and the 9-1-1 operator, the 9-1-1 operator
may be able to open a voice connection with the
vehicle to determine if additional help is needed. Once
the 9-1-1 operator opens a voice connection with the
vehicle’s 9-1-1 Call system, the operator should be able
to speak with you or other vehicle occupants and hear
sounds occurring in the vehicle. The vehicle’s 9-1-1
Call system will attempt to remain connected with the
9-1-1 operator until the 9-1-1 operator terminates the
connection. 5. The 9-1-1 operator may attempt to contact appropriate
emergency responders and provide them with impor-
tant vehicle information and GPS coordinates.
WARNING!
•If anyone in the vehicle could be in danger (e.g., fire
or smoke is visible, dangerous road conditions or
location), do not wait for voice contact from a 9-1-1
operator. All occupants should exit the vehicle im-
mediately and move to a safe location.
• Never place anything on or near the vehicle’s oper-
able 1X(voice/data) or 3G(data) network and GPS
antennas. You could prevent operable 1X(voice/data)
or 3G(data) network and GPS signal reception,
which can prevent your vehicle from placing an
emergency call. An operable 1X(voice/data) or
3G(data) network and GPS signal reception is re-
quired for the 9-1-1 Call system to function properly.
• The 9-1-1 Call system is embedded into the vehicle’s
electrical system. Do not add aftermarket electrical
equipment to the vehicle’s electrical system. This
may prevent your vehicle from sending a signal to
initiate an emergency call. To avoid interference that
