ignition Ram 3500 Chassis Cab 2020 Owners Manual

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.

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.

ENGINE RUNAWAY
Diesel engine runaway is a rare condition
affecting diesel engines, where the engine
consumes its own lubrication oil and runs at
higher and higher RPM until it overspeeds to a
point where it destroys itself due to either
mechanical failure or engine seizure through
lack of lubrication.
WARNING!
In case of engine runaway due to flammable
fumes from fuel spills or turbocharger oil
leaks being sucked into the engine, do the
following to help avoid personal injury and/or
vehicle damage:
Turn the ignition switch to the OFF position.
Using a CO2 or dry chemical type fire extin -
guisher, direct the spray from the fire extin -
guisher into the grille on the passenger side
so that the spray enters the engine air
intake.
The inlet for the engine air intake is located
behind the passenger side headlamp and
receives air through the grille.
