2020 RAM CHASSIS CAB display

250STARTING AND OPERATING
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 prop -
erly. The ParkSense 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 on the fascia/bumper while
driving the vehicle. Failure to do so can result
in the system misinterpreting a close
obstacle as a sensor problem, causing the
“Wipe Sensors” message or providing false
alerts.
PARKSENSE FRONT AND REAR PARK ASSIST
The ParkSense Front and Rear 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 Precau -
tions” in this section for limitations of this
system and recommendations.
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.
Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly is disconnected 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 indica -
tion 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 ParkSense 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.

STARTING AND OPERATING251
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 Park -
Sense operating speed. 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
Builder’s 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 approxi
-
mately 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.
The six ParkSense sensors, located in the front
fascia/bumper, monitor the area in front of the
vehicle that is within the sensors’ field of view.
The sensors can detect obstacles from approxi -
mately 12 inches (30 cm) up to 47 inches
(120 cm) from the front fascia/bumper in the
horizontal direction, depending on the location,
type and orientation of the obstacle.ParkSense Warning Display
The ParkSense Warning screen is located within
the instrument cluster display. It provides visual
warnings to indicate the distance between the
rear fascia/bumper and/or front fascia/bumper
and the detected obstacle. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
ParkSense Display
The warning display will turn on indicating the
system status when the vehicle is in REVERSE
or when the vehicle is in DRIVE and an obstacle
has been detected.
The system will indicate a detected obstacle by
showing a single arc in one or more of the rear
regions (left/center/right) based on the
obstacle’s distance and location relative to the
vehicle.

Single 1/2 Second Tone

252STARTING AND OPERATING

Slow Tone
Slow Tone For Rear Only Fast Tone For Rear Only
Fast Tone Continuous Tone

If an obstacle is detected in one or more of the
rear regions (left/center/right), the display will
show a single arc in the left, center, or rear
region and the system will produce a tone. As
the vehicle moves closer to the obstacle, 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.
The vehicle is close to the obstacle when the
display shows one flashing arc and sounds a
continuous tone. The following chart shows the
warning alert operation when the system is
detecting an obstacle:

When the gear selector is moved to
REVERSE and the Front or Rear
system is disabled, the instrument
cluster display will show a vehicle
graphic with an “Off” message overlay over the
system that is off (Front or Rear system). This vehicle graphic will be displayed for as long as
the vehicle is in REVERSE.
The Front or Rear ParkSense switch LED will be
on when Front or Rear ParkSense is disabled or
requires service. The Front or Rear ParkSense
switch LED will be off when the Front or Rear
system is enabled. If the Front or Rear Park
-
Sense switch is pushed, and the system
requires service, the Front or Rear ParkSense
switch LED will blink momentarily, and then the
LED will be on.
Service The ParkSense Front/Rear Park
Assist System
During vehicle start up, when the Front/Rear
ParkSense System has detected a faulted
condition, the instrument cluster display will
show the "Front/Rear ParkSense Unavailable
Service Required" or the "Front/Rear Park -
Sense 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
“Wipe Sensors.” If the system needs service,
the display overlay will read “Service.” Under
this condition, ParkSense will not operate. If "Front/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 "Front/Rear ParkSense Unavailable Service
Required" appears in the instrument cluster
display, see an authorized dealer.

256STARTING AND OPERATING
LANESENSE — IF EQUIPPED
LaneSense Operation
The LaneSense system is operational at speeds
above 37 mph (60 km/h) and below 112 mph
(180 km/h). It uses a forward looking camera to
detect lane markings and measure vehicle posi -
tion within the lane boundaries.
When both lane markings are detected and the
driver unintentionally drifts out of the lane while
no turn signal has been applied OR the driver
departs the lane on the opposite side of the
applied turn signal (if the left turn signal is
applied and the vehicle departs to the right), the
LaneSense system provides a haptic warning in
the form of torque applied to the steering wheel
to prompt the driver to remain within the lane
boundaries. The LaneSense system will also
provide a visual warning through the instrument
cluster display to prompt the driver to remain
within the lane boundaries.
The driver may manually override the haptic
warning by applying torque into the steering
wheel at any time. When only a single lane marking is detected
and the driver unintentionally drifts across that
lane marking (no turn signal applied), the Lane
-
Sense system provides a visual warning
through the instrument cluster display to
prompt the driver to remain within the lane.
When only a single lane marking is detected, a
haptic (torque) warning will not be provided.
NOTE:
When operating conditions have been met, the
LaneSense system will monitor if the driver’s
hands are on the steering wheel and provides
an audible and visual warning to the driver
when the driver’s hands are not detected on the
steering wheel. The system will cancel if the
driver does not return their hands to the wheel.
Turning LaneSense On Or Off
The LaneSense button is located on
the switch panel below the Uconnect
display.
NOTE:
If your vehicle is equipped with a 12–inch
Uconnect Display screen, the LaneSense button
is located above the display. To turn the LaneSense system on, push the
LaneSense button (LED turns off). A “Lane
-
Sense On” message is shown in the instrument
cluster display.

Lane Sense On Message

To turn the LaneSense system off, push the
LaneSense button again (LED turns on).
NOTE:
The LaneSense system will retain the last
system state (on or off) from the last ignition
cycle when the ignition is changed to the
ON/RUN position.

STARTING AND OPERATING257
LaneSense Warning Message
The LaneSense system will indicate the current
lane drift condition through the instrument
cluster display.
When the LaneSense system is on, the lane
lines are gray when both of the lane boundaries
have not been detected and the LaneSense tell -
tale is solid white.

System ON (Gray Lines) With White Telltale Left Lane Departure — Only Left Lane Detected

When the LaneSense system is on, the Lane -
Sense Telltale is solid white when only the
left lane marking has been detected and the
system is ready to provide visual warnings in
the instrument cluster display if an uninten -
tional lane departure occurs on the left side.
When the LaneSense system senses the lane
has been approached and is in a lane depar -
ture situation, the visual warning in the
instrument cluster display will show the left
lane line flashing yellow (on/off). The Lane -
Sense telltale changes from solid white to
flashing yellow.

Lane Crossed (Flashing Yellow Lane Line) With Yellow Telltale
NOTE:
The LaneSense system operates with similar
behavior for a right lane departure when only
the right lane marking has been detected.
Left Lane Departure — Both Lane Lines
Detected

When the LaneSense system is on, and both
the lane markings have been detected, the
system is "armed" to provide visual warnings
in the instrument cluster display and a torque
warning in the steering wheel if an uninten -
tional lane departure occurs. The lane lines
turn from gray to white and the LaneSense
telltale is solid green.

258STARTING AND OPERATING
When the LaneSense system senses a lane
drift situation, the left lane line turns solid
yellow. The LaneSense telltale changes
from solid green to solid yellow. At this time
torque is applied to the steering wheel in the
opposite direction of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.

Lane Approached (Solid Yellow Lane Line) With Solid Yellow Telltale

When the LaneSense system senses the lane
has been approached and is in a lane depar -
ture situation, the left lane line flashes yellow
(on/off). The LaneSense telltale changes
from solid yellow to flashing yellow. At this
time torque is applied to the steering wheel in
the opposite direction of the lane boundary. For example: If approaching the left side of
the lane the steering wheel will turn to the
right.

Lane Crossed (Flashing Yellow Lane Line) With Flashing Yellow Telltale

NOTE:
The LaneSense system operates with similar
behavior for a right lane departure.
Changing LaneSense Status
The LaneSense system has settings to adjust
the intensity (Low/Medium/High) of the torque
warning and the warning zone sensitivity (Early/
Medium/Late) that you can configure through
the Uconnect system screen. Refer to
“Uconnect Settings” in “Multimedia” for further
information. NOTE:
When enabled the system operates above
37 mph (60 km/h) and below 112 mph
(180 km/h).
Use of the turn signal suppresses the warn -
ings.
The system will not apply torque to the
steering wheel whenever a safety system
engages (Anti-Lock Brakes, Traction Control
System, Electronic Stability Control, Forward
Collision Warning, etc.).
PARKVIEW REAR BACK UP CAMERA
Your vehicle may be equipped with the
ParkView Rear Back Up Camera that allows you
to see a image of the rear surroundings of your
vehicle whenever the gear selector is put into
REVERSE or whenever it is initiated through the
"Backup Camera" button in the "Controls"
menu. Whenever the gear selector is put into
REVERSE, the image will be displayed in the
rearview mirror display (if equipped) or
Uconnect screen (if equipped). If the image is
displayed in the Uconnect screen, a caution
note to “check entire surroundings” will display
across the top of the screen. After five seconds
this note will disappear.
