310 STARTING AND OPERATING
ParkSense  can  be  active  only  when  the  gear  selector  is  in
REVERSE. If ParkSense is enabled at this gear selector posi -
tion, the system will remain active until the vehicle speed is
increased  to  approximately  7 mph  (11 km/h)  or  above.
When in REVERSE and above the system's operating speed,
a warning will appear within the instrument cluster display
indicating  the  vehicle  speed  is  too  fast.  The  system  will
become  active  again  if  the  vehicle  speed  is  decreased  to
speeds less than approximately 6 mph (9 km/h).
ParkSense Sensors
For  the  3500,  4500  and  5500  Chassis  Cab  vehicles,  the  rear
ParkSense sensors are shipped loose. Please refer to the Ram
Body Builders Guide for more information.
The  four  ParkSense  sensors  are  to  be  located  in  the  rear
fascia/bumper, and monitor the area behind the vehicle that
is within the sensors’ field of view.
The  sensors  can  detect  obstacles  from  approximately
18 inches  (45  cm)  up  to  79 inches  (200  cm)  from  the  rear
fascia/bumper in the horizontal direction, depending on the
location, type and orientation of the obstacle.
NOTE:
If  equipped  as  a  dually,  the  ParkSense  system  has  six  rear
sensors to assist in detection around the dually flares. ParkSense Warning Display
The  ParkSense  Warning  screen  is  located  within  the  instru -
ment cluster display. It provides visual warnings to indicate
the  distance  between  the  rear  fascia/bumper  and  the
detected  obstacle.  Refer  to  “Instrument  Cluster  Display”  in
“Getting To Know Your Instrument Panel” for further infor -
mation.
ParkSense Display
When  the  vehicle  is  in  REVERSE,  the  warning  display  will
turn on indicating the system status.
The  system  will  indicate  a  detected  obstacle  by  showing  a
single  arc  in  the  left  and/or  right  rear  regions  based  on  the
object’s distance and location relative to the vehicle.
If an object is detected in the left and/or right rear region, the
display  will  show  a  single  solid  arc  in  the  left  and/or  right
rear  region  and  the  system  will  produce  a  tone.  As  the
vehicle moves closer to the object, the display will show the
single  arc  moving  closer  to  the  vehicle  and  the  tone  will
change  from  a  single  1/2  second  tone  to  slow,  to  fast,  to
continuous.

Enabling And Disabling ParkSense
ParkSense  can  be  enabled  and  disabled  with  the  ParkSense
switch.
When  the  gear  selector  is  moved  to  REVERSE  and
the  system  is  disabled,  the  instrument  cluster
display  will  show  the  vehicle  graphic  with  “Off”
over the arcs for as long as the vehicle is in REVERSE.
NOTE:
The  ParkSense  system  will  automatically  disable  when  the
system  detects  that  a  trailer  with  trailer  brakes  has  been
connected  to  the  Integrated  Trailer  Brake  Module.  The
instrument cluster display will show an “Off” message over
the arcs if the ParkSense system is off, or a “Trailer” message
if the system is on, for as long as the vehicle is in REVERSE.
The  ParkSense  switch  LED  will  be  on  when  ParkSense  is
disabled  or defective. The  ParkSense switch LED will be off
when the system is enabled.
If the ParkSense switch is pushed, and the system is disabled
or  requires  service,  the  ParkSense  switch  LED  will  blink
momentarily, and then the LED will be on. Service The ParkSense Rear Park Assist System
During  vehicle  start  up,  when  the  Rear  ParkSense  System
has  detected  a  faulted  condition,  the  instrument  cluster
display  will  show  the  "Rear  ParkSense  Unavailable  Service
Required" or the "Rear ParkSense Unavailable Wipe Sensors"
message.
When  the  gear  selector  is  moved  into  REVERSE,  a  vehicle
graphic  will  show  in  the  instrument  cluster  display,  along
with the display overlay “Rear ParkSense Unavailable Wipe
Sensors.” If the system needs service, the display overlay will
read “Rear ParkSense Unavailable Service Required” Under
this condition, ParkSense will not operate.
If "Rear ParkSense Unavailable Wipe Sensors" appears in the
instrument  cluster  display  make  sure  the  outer  surface  and
the underside of the rear fascia/bumper is clean and clear of
snow, ice, mud, dirt or other obstruction, and then cycle the
ignition.  If  the  message  continues  to  appear,  see  an  autho -
rized dealer.
If "Rear ParkSense Unavailable Service Required" appears in
the instrument cluster display, see an authorized dealer. 5

316 STARTING AND OPERATING
(Continued)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 rear bumper is free of snow, ice, mud, dirt
and  debris  to  keep  the  ParkSense  system  operating  prop -
erly.
• Jackhammers,  large  trucks,  and  other  vibrations  could
affect the performance of ParkSense.
• When  you  move  the  gear  selector  into  REVERSE  with
ParkSense  turned  off,  the  instrument  cluster  display  will
show  "Off"  on  the  vehicle  graphic  arcs  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  Park -
Sense  system  might  not  detect  an  obstacle  behind  the
fascia/bumper,  or  it  could  provide  a  false  indication  that
an obstacle is behind the fascia/bumper.
• Ensure  the  ParkSense  system  is  OFF  if  objects  such  as
bicycle  carriers,  trailer  hitches,  etc.,  are  placed  within
18 inches (45 cm) of the rear fascia/bumper while driving
the vehicle. Failure to do so can result in the system misin -
terpreting a close obstacle as a sensor problem, causing the
"Rear  ParkSense  Unavailable  Service  Required"  message
to appear in the instrument cluster display.
WARNING!
• Drivers  must  be  careful  when  backing  up  even  when
using  ParkSense.  Always  check  carefully  behind  your
vehicle,  look  behind  you,  and  be  sure  to  check  for
pedestrians,  animals,  other  vehicles,  obstructions,  and
blind spots before backing up. You are responsible for
safety  and  must  continue  to  pay  attention  to  your
surroundings.  Failure  to  do  so  can  result  in  serious
injury or death.

STARTING AND OPERATING 317
PARKSENSE FRONT AND REAR PARK ASSIST  
The  ParkSense  Park  Assist  system  provides  visual  and
audible indications of the distance between the rear, and/or
front  fascia/bumper,  and  a detected obstacle  when backing
up or moving forward, e.g. during a parking maneuver.
Refer  to  “ParkSense  System  Usage  Precautions”  in  this
section for limitations of this system and recommendations.
ParkSense  will  retain  the  last  system  state  (enabled  or
disabled)  from  the  last  ignition  cycle  when  the  ignition  is
changed to the ON/RUN position.
ParkSense  can  be  active  only  when  the  gear  selector  is  in
REVERSE or DRIVE. If  ParkSense is enabled at one of these
gear  selector  positions,  the  system  will  remain  active  until
the  vehicle  speed  is  increased  to  approximately  7 mph
(11 km/h) or above. A warning will appear in the instrument
cluster  display  when  the  vehicle  is  in  REVERSE,  indicating
the vehicle is above ParkSense operating speed. The  system
will become active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h).• Before  using  ParkSense,  it  is  strongly  recommended
that  the  ball  mount  and  hitch  ball  assembly  is  discon -
nected from the vehicle 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 loudspeaker sounds the continuous  tone.  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!
• ParkSense  is  only  a  parking  aid  and  it  is  unable  to
recognize  every  obstacle,  including  small  obstacles.
Parking  curbs  might  be  temporarily  detected  or  not
detected  at  all.  Obstacles  located  above  or  below  the
sensors  will  not  be  detected  when  they  are  in  close
proximity.
• The  vehicle  must  be  driven  slowly  when  using  Park -
Sense  in  order  to  be  able  to  stop  in  time  when  an
obstacle  is  detected.  It  is  recommended that the driver
looks over his/her shoulder when using ParkSense. WARNING!  (Continued)
