2022 RAM PROMASTER brake

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

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.

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.
ACC Hill Example

22_VF_OM_EN_USC_t.book Page 89

90STARTING AND OPERATING
LANE CHANGING
ACC may not detect a vehicle until it is completely
in the lane in which you are traveling. In the
following lane changing example, ACC has not yet
detected the vehicle changing lanes and it may not
detect the vehicle until it's too late for the ACC
system to take action. ACC may not detect a
vehicle until it is completely in the lane. There may
not be sufficient distance to the lane-changing
vehicle. Always be attentive and ready to apply the
brakes if necessary.

Lane Changing Example

NARROW VEHICLES
Some narrow vehicles traveling near the outer
edges of the lane or edging into the lane are not
detected until they have moved fully into the lane.
There may not be sufficient distance to the vehicle
ahead.
Narrow Vehicle Example

STATIONARY OBJECTS AND VEHICLES
ACC does not react to stationary objects or
vehicles. For example, ACC will not react in
situations where the vehicle you are following exits
your lane and the vehicle ahead is stopped in
your lane. It will consider this stopped vehicle a
stationary object as it did not previously detect
movement from it. Always be attentive and ready
to apply the brakes if necessary.

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.

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
