2022 RAM 1500 warning

184STARTING AND OPERATING
When the condition that deactivated the system is
no longer present, the system will return to the
“Adaptive Cruise Control Off” state and will resume
function by simply reactivating it.
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the radar
sensor realigned at an authorized dealer.
Installing a snow plow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display and a chime will
sound when conditions temporarily limit system
performance. This most often occurs at times of
poor visibility, such as in snow or heavy rain and
fog. The ACC system may also become temporarily
blinded due to obstructions, such as mud, dirt, or
ice on windshield, driving directly into the sun and
fog on the inside of glass. In these cases, the
instrument cluster display will show “ACC/FCW
Limited Functionality Clean Front Windshield” and
the system will have degraded performance. This message can sometimes be displayed while
driving in adverse weather conditions. The ACC/
FCW system will recover after the vehicle has left
these areas. Under rare conditions, when the
camera is not tracking any vehicles or objects in its
path this warning may temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rear view
mirror. They may require cleaning or removal of an
obstruction.
When the condition that created limited
functionality is no longer present, the system will
return to full functionality.
NOTE:If the “ACC/FCW Limited Functionality Clean Front
Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the windshield and
forward facing camera inspected at an authorized
dealer.
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster
displays “ACC/FCW Unavailable Service Required”
or “Cruise/FCW Unavailable Service Required”,
there may be an internal system fault or a
temporary malfunction that limits ACC
functionality. Although the vehicle is still drivable under normal conditions, ACC will be temporarily
unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem
persists, see an authorized dealer.
Precautions While Driving With ACC
NOTE:
Aftermarket add-ons such as snow plows, lift
kits, and brush/grille bars can hinder module
performance. Ensure the radar/camera has no
obstructions in the field of view.
Height modifications can limit module perfor
-
mance and functionality.
Do not put stickers or easy passes over the
camera/radar field of view.
Any modifications to the vehicle that may
obstruct the field of view of the radar/camera
are not recommended.
In certain driving situations, ACC may have
detection issues. In these cases, ACC may brake
late or unexpectedly. The driver needs to stay alert
and may need to intervene. The following are
examples of these types of situations:

22_DT_OM_EN_USC_t.book Page 184

STARTING AND OPERATING187
ParkSense will retain its last known configura -
tion state for the automatic braking function
through ignition cycles.
Trailer hitch ball assembly may cause false
braking events if left attached after towing.
The automatic braking function is intended to
assist the driver in avoiding possible collisions with
detected obstacles when backing up in REVERSE
gear.
NOTE:
The system is provided to assist the driver and
not to substitute the driver.
The driver must stay in full control of the
vehicle's acceleration and braking and is
responsible for the vehicle's movements.
For limitations of this system and usage
precautions, see Ú page 191.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition cycle
when the ignition is placed in the ON/RUN position.
ParkSense can be active only when the gear
selector is in REVERSE or DRIVE. If ParkSense is
enabled while in one of these gears, 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 indicating the vehicle speed is above ParkSense operating speed while in REVERSE. The
system will become active again if the vehicle
speed is decreased to speeds less than
approximately 6 mph (9 km/h).
PARKSENSE SENSORS
The four ParkSense sensors (six if equipped with
Active Parksense), located in the front fascia/
bumper, monitor the area in front of the vehicle
that is within the sensors’ field of view, and the four
ParkSense sensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that
is within the sensors’ field of view. The front
sensors can detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from
the front fascia/bumper. The rear sensors can
detect obstacles from approximately 12 inches
(30 cm) up to 79 inches (200 cm). These distances
depend on the location, type and orientation of the
obstacle in the horizontal direction.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen is located within
the instrument cluster display Ú
page 114. It
provides visual warnings to indicate the distance
between the rear fascia/bumper and/or front
fascia/bumper and the detected obstacle.
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 the left, right, or center
regions based on the obstacle’s distance and
location relative to the vehicle.
If an obstacle is detected in the center front region,
the display will show a single solid arc in the center
front region with no chime. As the vehicle moves
closer to the obstacle, the display will show the
single arc moving closer to the vehicle and a fast
chime will be heard and will change from fast to
continuous.
If an obstacle is detected in the left and/or right
front region, the display will show a single flashing
arc in the left and/or right front region and will
produce a fast chime. 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 fast to continuous.

STARTING AND OPERATING191
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
Ensure that the front and rear fascias/bumpers
are free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of Park -
Sense.
When you turn Front or Rear ParkSense off, the
instrument cluster display will show a vehicle
graphic of the Front or Rear ParkSense on/off
state for two seconds. Furthermore, once you
turn Front or Rear 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 Front or Rear ParkSense
is turned off, the instrument cluster display will
show a vehicle graphic with "OFF" in the corre -
sponding side. This vehicle graphic will be
displayed 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 obstacles such as bicycle carriers,
trailer hitches, etc. are placed near the rear
fascia/bumper. Failure to do so can result in the
system misinterpreting a close obstacle as a
sensor problem, causing the “PARKSENSE
UNAVAILABLE SERVICE REQUIRED” message to
be appear in the instrument cluster display.
ParkSense should be disabled when the tailgate
is in the lowered or open position. A lowered tail -
gate could provide a false indication that an
obstacle is behind the vehicle and could also
cause a false braking event.
The Rear 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 Front ParkSense system will automatically
disable if a snow plow has been connected to
the vehicle.
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 recom -
mended that the ball mount and hitch ball
assembly be 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/bumper when the vehicle sounds
the continuous tone. Also, the sensors could
detect the ball mount and hitch ball assembly,
depending on its size and shape, and give a
false indication that an obstacle is behind the
vehicle, and could cause false braking.

STARTING AND OPERATING195
The system may then instruct the driver to wait for
steering to complete before then instructing to
check surroundings and move backward.

Move Backward Into Parallel Parking Space
Move Backward Into Perpendicular Parking Space
The system may instruct several more gear shifts
(DRIVE and REVERSE), with hands off of the
steering wheel, before instructing the driver to
check surroundings and complete the parking
maneuver.
When the vehicle is in the parking position, the
maneuver is complete and the driver will be
instructed to check the vehicle's parking position,
then shift the vehicle into PARK. The message
"Active ParkSense Complete - Check Parking
Position" will be displayed momentarily.
NOTE:
It is the driver's responsibility to use the brake
and accelerator during the semi-automatic
parking maneuver.
It is the driver's responsibility to use the brake
and stop the vehicle. The driver should check
their surroundings and be prepared to stop the
vehicle either when instructed to, or when driver
intervention is required.
When the system instructs the driver to remove
their hands from the steering wheel, the driver
should check their surroundings and begin to
back up slowly.
The ParkSense Active Park Assist system will
allow a maximum of eight shifts between DRIVE
and REVERSE. If the maneuver cannot be
completed within eight shifts, the system will
cancel and the instrument cluster display will
instruct the driver to complete the maneuver
manually.
The system will cancel the maneuver if the
vehicle speed exceeds 5 mph (7 km/h) during
active steering guidance into the parking space.
The system will provide a warning to the driver
at 3 mph (5 km/h) that tells them to slow down.
The driver is then responsible for completing the
maneuver if the system is canceled.
If the system is canceled during the maneuver
for any reason, the driver must take control of
the vehicle.

196STARTING 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). The LaneSense system uses a
forward looking camera to detect lane markings
and measure vehicle position within the lane
boundaries.
When both lane markings are detected and the
driver drifts out of the lane (no turn signal applied),
the LaneSense system provides a haptic warning
in the form of torque applied to the steering wheel,
as well as a visual warning in the instrument
cluster display, to prompt the driver to remain
within the lane boundaries.
The driver may manually override the haptic
warning by applying force into the steering wheel at
any time.
When only a single lane marking is detected and
the driver drifts across the lane marking (no turn
signal applied), the LaneSense 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 or a 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 provide an
audible and visual warning to the driver if
removed. The system will cancel if the driver
does not return their hands to the wheel.
LaneSense will disable when a snow plow is
connected to the vehicle.
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 “LaneSense
On” message is shown in the instrument cluster
display.
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 placed in the ON/RUN position.
WARNING!
Drivers must be careful when performing
parallel or perpendicular parking maneuvers
even when using the ParkSense Active Park
Assist system. Always check carefully behind
and in front of your vehicle, look behind and in
front of you, and be sure to check for
pedestrians, animals, other vehicles,
obstructions, and blind spots before backing up
and moving forward. 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.
CAUTION!
The ParkSense Active Park Assist system 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’ field of view will not be
detected when they are in close proximity.

The vehicle must be driven slowly when using
the ParkSense Active Park Assist system in
order to be able to stop in time when an
obstacle is detected. It is recommended that
the driver looks over his/her shoulders when
using the ParkSense Active Park Assist system.

STARTING AND OPERATING197
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 telltale
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 unintentional
lane departure occurs on the left side.
When the LaneSense system senses the lane
has been approached and is in a lane departure
situation, the visual warning in the instrument
cluster display will show the left lane line
flashing yellow (on/off). The LaneSense telltale
changes from solid white to flashing yellow.

Lane Approached (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 unintentional lane
departure occurs. The lane lines turn from gray
to white and the LaneSense telltale is solid
green.

22_DT_OM_EN_USC_t.book Page 197

198STARTING 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 Sensed (Solid Yellow Lane Line) With Solid Yellow Telltale
When the LaneSense system senses the lane
has been approached and is in a lane departure
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 Approached (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 of the torque warning and the warning
zone sensitivity (Early/Medium/Late) that you can
configure through the Uconnect system
Úpage 234.
NOTE:
When enabled the system operates above
37 mph (60 km/h) and below 112 mph
(180 km/h).
The warnings are disabled with use of the
turn signal.
The system will not apply torque to the steering
wheel whenever a safety system engages
(Anti-Lock Brakes, Traction Control System,
