2022 RAM PROMASTER warning

86STARTING AND OPERATING
NOTE:
If your vehicle is at standstill longer than two
seconds, the driver will either have to push the
RES (resume) button, or apply the accelerator
pedal to reengage the Adaptive Cruise Control
(ACC) to the existing set speed.
ACC cannot be resumed if there is a stationary
vehicle in front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set
speed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button. U.S. Speed (mph)
Pushing the SET (+)
, or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.

If the button is continually pushed, the set speed
will continue to adjust in 5 mph increments until
the button is released. The new set speed is
reflected in the instrument cluster display.

Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.

If the button is continually pushed, the set speed
will continue to adjust in 10 km/h increments
until the button is released. The new set speed is
reflected in the instrument cluster display.

NOTE:When you override and push the SET (+) button or
SET (-) button, the new set speed will be the current
speed of the vehicle.
When ACC Is Active

When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the vehicle.

The ACC system decelerates the vehicle to a full
stop when following the vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
after two seconds 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.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal.
In addition, downshifting may occur while
climbing uphill or descending downhill. This is
normal operation and necessary to maintain set
speed. When driving uphill and downhill, the
ACC system will cancel if the braking tempera -
ture exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set
by varying the distance setting between four bars
(longest), three bars (long), two bars (medium) and
one bar (short). Using this distance setting and
the vehicle speed, ACC calculates and sets the
distance to the vehicle ahead. This distance
setting will show in the instrument cluster display.
WARNING!

The Resume function should only be used if traffic
and road conditions permit. Resuming a set speed
that is too high or too low for prevailing traffic and
road conditions could cause the vehicle to
accelerate or decelerate too sharply for safe
operation. Failure to follow these warnings can result
in a collision and death or serious personal injury.

22_VF_OM_EN_USC_t.book Page 86

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.

88STARTING AND OPERATING
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.

22_VF_OM_EN_USC_t.book Page 88

STARTING AND OPERATING89
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rearview
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 Limited Functionality Camera Blocked”
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 WARNING

If the system turns off, and the instrument cluster
display reads “ACC Unavailable Service Required” or
“Cruise 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
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:
TOWING A TRAILER

Towing a trailer is not recommended when using ACC.

OFFSET DRIVING
ACC may not detect a vehicle in the same lane that
is offset from your direct line of travel, or a vehicle
merging in from a side lane. There may not be
sufficient distance to the vehicle ahead. The offset
vehicle may move in and out of the line of travel,
which can cause your vehicle to brake or
accelerate unexpectedly.

Offset Driving Condition Example

TURNS AND BENDS
When driving on a curve with ACC engaged, the
system may increase or decrease the vehicle
speed for stability, with no vehicle ahead detected.
Once the vehicle is out of the curve, the system will
resume your original set speed. This is a part of
normal ACC system functionality.
NOTE:On tight turns ACC performance may be limited.
USING ACC ON HILLS
ACC performance may be limited when driving on
hills. ACC may not detect a vehicle in your lane
depending on the speed, vehicle load, traffic
conditions, and the steepness of the hill.

Supplemental Information
Supplemental information may be displayed along
with a newly detected speed limit indicating
special circumstances the driver should be aware
of. Available supplemental information includes:
School
Construction
Rain
Snow
Fog
Speed Limit Exceeded
When the vehicle’s speed exceeds the displayed
speed limit by 3 mph (5 km/h), the speed limit sign
on the instrument cluster display will show a red
outline to alert the driver.
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.

Information (School Zone)
2 — No Passing Zone Detected
3 — Next Speed Limit Detected
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 acti
-
vated.
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.

Active Driving Assist Engaged (Steering Wheel Green)

WARNING!

The Active Driving Assist (ADA) system is a
convenience system. It is not a substitute for active
driver involvement. It is always the driver’s
responsibility to be attentive of road traffic, weather
conditions, vehicle speed, distance to the vehicle
ahead, position in the lane compared to other
vehicles, and brake operation to ensure safe
operation of the vehicle under all road conditions.
Your complete attention is always required while
driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a
collision and death or serious personal injury.
You should turn off the Active Driving Assist system:

When driving in fog, heavy rain, heavy snow,
sleet, and complex driving situations (i.e., in
construction zones).
When entering a highway off ramp, when
driving on roads that are icy, snow covered, or
slippery.
When circumstances do not allow safe driving.

94STARTING AND OPERATING
NOTE:Along with the color change of the steering wheel
image, the “glow” effect of the instrument cluster
display will also change to green when ADA is
engaged.
System Engagement Conditions
The following conditions must be met before the
system will engage:
Active Driving Assist system is enabled
ACC is engaged
System detects visible lane markings
Vehicle is traveling below 93 mph (150 km/h)
Vehicle is centered in lane
Turn signal is not activated
Vehicle is not in a tight curve
Driver has hands on steering wheel
NOTE:For the system to detect the driver’s hands on the
steering wheel, the wheel must be gripped on the
outside. Gripping the inside areas of the steering
wheel will not satisfy the hands-on condition to
engage the system.
Do Not Grip Inside Of Steering Wheel

System Deactivation
The system will be deactivated in any of the
following situations:
If the system has detected driver inattentive -
ness, and has gone through all escalation warn -
ings after hands are no longer detected on the
steering wheel
If lane markings are no longer detected
If the Active Driving Assist on/off button is
pushed again (ADA will turn off)
If a turn signal is used
If the driver applies torque to the steering wheel

If the vehicle speed exceeds 93 mph (150 km/h)

If the ACC system is deactivated

If the Forward Collision Warning (FCW) system
becomes active and is providing warnings/braking

NOTE:
Pushing the Active Driving Assist on/off button
will turn the system off. All other deactivation
conditions will place the system back into the
“enabled” state with the steering wheel indi -
cator displayed in grey until all engagement
conditions are met again.
When the system is deactivated, the system
status indicator lights will turn off, Active Lane
Management will return to its previous state,
and ACC will disable.
INDICATIONS ON THE DISPLAY
The Active Driving Assist system status can always
be viewed in the instrument cluster display, and
status changes are shown by changes in color of
the system’s indicator lights.
As the system detects driver inattentiveness as
previously described Ú page 92, the system
status indicator lights will change from green, to
yellow, to red, while the steering wheel icon on
the display moves up the screen to the center.
The following indicators will change in color as
warnings to the driver escalate:
Active Driving Assist Indicator (steering wheel
icon in the instrument cluster display)
Glow effect of the instrument cluster display

22_VF_OM_EN_USC_t.book Page 94

STARTING AND OPERATING95
If driver attention is not returned, the system will
deactivate.
Active Driving Assist Indicators Are Off
ADA is not turned on/enabled by the driver.
Active Driving Assist Indicators Are Grey
ADA is turned on/enabled by the driver, but the
system is not actively providing steering to the
vehicle.

warning the driver to place hands on the
steering wheel.
NOTE:The driver MUST replace hands on the steering
wheel and take control of the vehicle when the
system is deactivated.
Active Driving Assist Cancelled Message

MINIMUM RISK MANEUVER
If the driver removes the hands from the steering
wheel, a counter will start in order to display and
activate visual and acoustic alerts. When the
hands absence is detected the system will start
Minimum Risk Maneuver for bringing the vehicle in
a safe position.
After 23 seconds from the absence of the hands
on the steering wheel, the Adaptive System Cruise
Control will apply a brake jerk to warn the driver to
take vehicle control. If, after another 3 seconds the
driver does not take the control of the vehicle, the
system will apply a second brake jerk.Subsequently, if the absence of hands on the
steering wheel persists, the system will apply an
automatic braking intervention to bring the vehicle
to the stop. As soon as the standstill condition is
reached, the hazard emergency lights will be
activated. Then, the system will unlock the doors
(if previously locked). If the driver will take the
control of the vehicle during the Minimum Risk
Maneuver by placing the hands on the steering
wheel or pressing the pedal throttle, the system
will behave normally and the Minimum Risk
Maneuver will be stopped.
SYSTEM STATUS

Along with changes in the system’s indicator lights
(green, yellow, and red), the system can also issue a
steering wheel vibration to accompany these warnings.
The vibration warning (if enabled) will occur if the
vehicle crosses a lane marker, for example, when
driving on a tight curve. This feature can be turned on
or off within the Uconnect system
