2022 RAM PROMASTER sensor

STARTING AND OPERATING85
NOTE:Fixed Speed Cruise Control can be used without
ACC enabled. To change between the different
modes, push the ACC on/off button which turns
the ACC and the Fixed Speed Cruise Control off.
Pushing the Fixed Speed Cruise Control on/off
button will result in turning on (changing to) Fixed
Speed Cruise Control mode.
If ACC is set when the vehicle speed is below
20 mph (32 km/h), the set speed will default to
20 mph (32 km/h).
NOTE:Fixed Speed Cruise Control cannot be set below
20 mph (32 km/h).
If either system is set when the vehicle speed is
above 20 mph (32 km/h), the set speed shall be
the current speed of the vehicle.
NOTE:
Keeping your foot on the accelerator pedal can
cause the vehicle to continue to accelerate
beyond the set speed. If this occurs, the Adap -
tive cruise control light will flash and, if a target
is detected by the sensor, the target graphics
will also flash.
If you continue to accelerate beyond the set
speed while ACC is enabled, the system will not
be controlling the distance between your vehicle
and the vehicle ahead. The vehicle speed will
only be determined by the position of the accel-
erator pedal.
Desired Driving Speed Through A Detected
Speed Sign
The Active Driving Assist (ADA) system allows the
driver to set the detected speed sign Úpage 91 as
the new desired driving speed. The Traffic Sign
Assist (TSA) system will suggest the new detected
speed sign on the cluster and then the driver can
decide to confirm the speed sign capturing by
pressing the RES (resume) button.
To Cancel
The following conditions cancel the ACC or Fixed
Speed Cruise Control systems:
The brake pedal is applied
The CANC (cancel) button is pushed
The Anti-Lock Brake System (ABS) activates
The gear selector is removed from the DRIVE
position
The Electronic Stability Control/Traction Control
System (ESC/TCS) activates
The vehicle parking brake is applied
The braking temperature exceeds normal range
(overheated)
To Turn Off
The system will turn off and clear the set speed in
memory if:
The Adaptive Cruise Control (ACC) on/off button
is pushed
The Fixed Speed Cruise Control on/off button is
pushed
The ignition is placed in the OFF position
To Resume
If there is a set speed in memory, push the RES
(resume) button and remove your foot from the
accelerator pedal. The instrument cluster display
will show the last set speed.
Resume can be used at any speed above 20 mph
(32 km/h) when only Fixed Speed Cruise Control is
being used.
Resume can be used at any speed above 0 mph
(0 km/h) when ACC is active.
WARNING!
In Fixed Speed Cruise Control mode (ACC not
enabled), the system will not react to vehicles
ahead. In addition, the proximity warning does
not activate and no alarm will sound even if you
are too close to the vehicle ahead since neither
the presence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected. Be sure
to maintain a safe distance between your vehicle
and the vehicle ahead. Always be aware which
mode is selected.4

STARTING AND OPERATING87

Distance Settings

To adjust the distance setting, push the Distance
Setting Button and release. Each time the button is
pushed, the distance setting decreases by one bar
(longer). Once the longest setting is reached, if the
button is pushed again it will be set to the shortest
setting available.
If a slower moving vehicle is detected in the same
lane, the instrument cluster display will show the
ACC Set With Target Detected Light. The system
will then adjust vehicle speed automatically to
maintain the distance setting, regardless of the
set speed.
The vehicle will then maintain the set distance until:

The vehicle ahead accelerates to a speed above
the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages Ú
page 84.
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:The brake lights will illuminate whenever the ACC
system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE!” will flash in the
instrument cluster display and a chime will sound
while ACC continues to apply its maximum braking
force.
NOTE:The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the Forward
Collision Warning system is applying the brakes
autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (ACC)
engaged and following a vehicle, the system will
provide an additional acceleration up to the ACC
set speed to assist in passing the vehicle. This
additional acceleration is triggered when the driver
utilizes the left turn signal and will only be active
when passing on the left hand side.
ACC Operation At Stop
In the event that the ACC system brings your
vehicle to a standstill while following a vehicle in
front, if the vehicle in front starts moving within two
seconds of your vehicle coming to a standstill, your
vehicle will resume motion without the need for
any driver action.
If the vehicle in front does not start moving within
two seconds of your vehicle coming to a standstill,
the driver will either have to push the RES (resume)
button, or apply the accelerator pedal to reengage
the ACC to the existing set speed.
NOTE:After the ACC system holds your vehicle at a stand -
still for approximately three consecutive minutes,
the parking brake will be activated, and the ACC
system will be cancelled.
While ACC is holding your vehicle at a standstill, if
the driver seat belt is unbuckled or the driver door
is opened, the parking brake will be activated, and
the ACC system will be cancelled.

Display Warnings And Maintenance
RADAR SENSOR UNAVAILABILITY WARNING
The “ACC Unavailable Wipe Front Radar Sensor”
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. The ACC system
may also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the instrument cluster display will display
the above message and the system will deactivate.
This message can sometimes be displayed while
driving in highly reflective areas (i.e. ice and snow,
or tunnels with reflective tiles). The ACC system will
recover after the vehicle has left these areas.
Under rare conditions, when the radar is not
tracking any vehicles or objects in its path this
warning may temporarily occur.
NOTE:If the “ACC Unavailable Wipe Front Radar Sensor”
warning is active, Fixed Speed Cruise Control can
be still enabled.
If weather conditions are not a factor, the driver
should examine the sensor. It may require cleaning
or removal of an obstruction. The sensor is located
in the center of the vehicle behind the lower grille.
To keep the ACC system operating properly, it is
important to note the following maintenance
items:
Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
Do not remove any screws from the sensor.
Doing so could cause an ACC system malfunc -
tion or failure and require a sensor realignment.
If the sensor or front end of the vehicle is
damaged due to a collision, see an authorized
dealer for service.
Do not attach or install any accessories near the
sensor, including transparent material or after -
market grilles. Doing so could cause an ACC
system failure or malfunction.
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 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 operation.
“ACC LIMITED FUNCTIONALITY CAMERA
BLOCKED” WARNING
The “ACC Limited Functionality Camera Blocked”
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 and fog on the inside of glass. In these
cases, the instrument cluster display will read
“ACC Limited Functionality Camera Blocked” and
the system will have degraded performance.
This message can sometimes be displayed while
driving in adverse weather conditions. The ACC
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.
WARNING!
When the ACC system is resumed, the driver
must ensure that there are no pedestrians,
vehicles or objects in the path of the vehicle.
Failure to follow these warnings can result in a
collision and death or serious personal injury.

ACTIVE DRIVING ASSIST SYSTEM —
IF EQUIPPED
OPERATION
The Active Driving Assist (ADA) system is combined
with the Adaptive Cruise Control (ACC) system, and
centers the vehicle in the driving lane while
traveling at speeds up to 93 mph (150 km/h).
Just like ACC, ADA will maintain a set speed as long
as the set distance between your vehicle and the
vehicle in front is maintained. ADA will also keep
your vehicle centered between the lane lines, and
monitor for other vehicles in adjacent lanes.
ADA uses sensors within the steering wheel to
monitor driver attentiveness. ADA requires the
driver’s hands on the steering wheel at all times.

Driving near highway toll booths
NOTE:If damage to the windshield occurs, have the wind
-
shield replaced by an authorized dealer as soon as
possible.
PARKSENSE FRONT/REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Park Assist system provides visual
and audible indications of the distance between
the rear, and if equipped, the front fascia/bumper
and a detected obstacle when backing up or
moving forward (e.g. during a parking maneuver).
For limitations of the system (e.g. during a parking
maneuver), see Ú page 101.
NOTE:
The system is designed 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
controlling the vehicle's movements.
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 is active when the gear selector is
shifted to REVERSE or to a forward gear and an
obstacle is detected, as long as the system is on.
When the gear selector shifted to NEUTRAL or
PARK, the system becomes inactive. When the
vehicle is moving forward, the system will remain
active until the vehicle speed remains below
approximately 11 mph (18 km/h). Reducing the
speed approximately below 9 mph (15 km/h), the
system will come back active. When the vehicle is
moving in REVERSE, the system will remain active
as long as the speed remains below the maximum
operating speed of 7 mph (11 km/h). When the
maximum speed limit is exceeded, the system is
disabled and the ParkSense switch LED with
illuminate. The system will become active again if
the vehicle speed reduces below approximately
6 mph (9 km/h).
WARNING!
To prevent serious injury or death:
Always remain alert and be ready to take
control of the vehicle in the event that the
Active Driving Assist system disables.

Always keep your hands on the steering wheel
when the Active Driving Assist system is activated.

Maintain a safe distance from other vehicles
and pay attention to traffic conditions.
Do not place any objects on the steering wheel
(e.g. steering wheel covers) which could inter
-
fere with the hand detection sensors.

STARTING AND OPERATING97
Interaction With Trailer Towing
The Park Assist system is automatically
deactivated when a trailer is hitched to the vehicle.
The system will be automatically activated as soon
as the trailer is removed.
PARKSENSE SENSORS

The six ParkSense sensors (four when vehicle is not
equipped with front sensors), located in the rear fascia/
bumper, and the six ParkSense sensors located in the
front fascia/bumper, monitor the area in front and
behind the vehicle that is within the sensors’ field of
view. The front sensors detect obstacles from
approximately 12 inches (30 cm) up to 39 inches
(100 cm) from the front fascia/bumper. The rear
sensors can detect obstacles from approximately
12 inches (30 cm) up to 55 inches (140 cm) from the
center of the rear fascia/bumper and up to 24 inches
(60 cm) from the corners of the rear fascia/bumper.
These distances depend on the location, type and
orientation of the obstacle in the horizontal direction.
Rear Park Assist Sensors Location

If several obstacles are detected, the ParkSense
system indicates the nearest obstacle.
The minimum height of a detectable obstacle
corresponds to the maximum height of an obstacle
that would clear the underside of the vehicle
during the parking maneuver.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen will only be
displayed if “Sound and Display” is selected in the
Uconnect system Ú page 120. The ParkSense Warning screen is located within
the instrument cluster display Ú
page 55. 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 and/or right front or
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 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.

PARKSENSE PARK ASSIST FAILURE
I
NDICATIONS
A malfunction of the ParkSense Park Assist
sensors or system is indicated, during REVERSE
gear engagement, by the instrument panel
warning icon.
The warning icon is illuminated and a
message is displayed in the instrument
cluster display (if equipped) Ú page 59.
The sensors and wiring are tested continuously
when the ignition is in the ON/RUN position.
Failures are indicated immediately if they occur
when the system is on.
Even if the system is able to identify that a specific
sensor is in failure condition, the instrument
cluster display shall indicate that the ParkSense
Park Assist system is unavailable, without
reference to the sensor in failure condition. If even
a single sensor fails, the entire system must be
disabled. The system is turned off automatically.
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 PARK ASSIST SYSTEM
U
SAGE PRECAUTIONS
NOTE:
Ensure that the front and rear fascia/bumper
are free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating properly.
Construction equipment, large trucks, and other
vibrations could affect the performance of
ParkSense.
When you turn ParkSense off, the instrument
cluster display will read “PARKSENSE OFF.”
Furthermore, once you turn ParkSense off, it
remains off until you turn it on again, even if you
cycle the ignition key.
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,
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 display.
NOTE:If any objects are attached to the bumper within a
6.5 ft (2 m) field of view, they will interfere and
cause false alerts and possibly blockage.
There may be a delay in the object detection
rate if the object is moving.
The operation of the rear sensors is automati
-
cally deactivated when the trailer's electric plug
is inserted in the vehicle's tow hook socket,
while the front sensors stay active and can
provide acoustic and visual warnings. The rear
sensors are automatically reactivated when the
trailer's cable plug is removed.
