2023 RAM PROMASTER cruise control

88STARTING AND OPERATING
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always be
aware of the feature selected.
Only one Cruise Control feature can operate at a
time. For example, if Fixed Speed Cruise Control
is enabled, Adaptive Cruise Control will be
unavailable, and vice versa.
CRUISE CONTROL
When engaged, the Cruise Control takes over
accelerator operations at speeds greater than
20 mph (32 km/h) up to the maximum speed of
100 mph (160 km/h).
The Cruise Control buttons are located on the right
side of the steering wheel.

WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the conditions,
and you could lose control and have an accident.
Do not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.
WARNING!
Leaving the Cruise Control system on when not
in use is dangerous. You could accidentally set
the system or cause it to go faster than you
want. You could lose control and have an
accident. Always ensure the system is off
when you are not using it.

STARTING AND OPERATING89
To Vary The Speed Setting
To Increase or Decrease The Set Speed
When the Cruise Control is set, you can increase
speed by pushing the SET (+) button or decrease
the 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 until the button is released, then
the new set speed will be established.

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 until the button is released, then
the new set speed will be established.

To Accelerate For Passing

While the Cruise Control is set, press the accelerator
to pass as you would normally. When the pedal is
released, the vehicle will return to the set speed.

USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise Control system maintains speed up and
down hills. A slight speed change on moderate hills
is normal. On steep hills, a greater speed loss or
gain may occur so it may be preferable to drive
without Cruise Control.
To Resume Speed
To resume a previously set speed, push the
RES button and release. Resume can be used at
any speed above 20 mph (32 km/h) up to the
maximum speed of 100 mph (160 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC
button, or normal brake pressure while slowing the
vehicle will deactivate the Cruise Control without
erasing the set speed from memory.
Pushing the on/off button or placing the ignition in the
OFF position erases the set speed from memory.

ADAPTIVE CRUISE CONTROL (ACC)

Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while traveling
on highways and major roadways. However, it is not a
safety system and not designed to prevent collisions.
The Cruise Control function performs differently if your
vehicle is not equipped with ACC

Ú
page 88.

ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your speed. ACC utilizes
a radar sensor and a forward facing camera
designed to detect a vehicle directly ahead of you
to maintain a set speed.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or accelerate (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.

Fixed Speed Cruise Control (ACC not enabled) will
not detect vehicles directly ahead of you. Always be
aware of the feature selected
Ú
page 280.

WARNING!

Cruise Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle
could go too fast for the conditions, and you could
lose control and have an accident. Do not use Cruise
Control in heavy traffic or on roads that are winding,
icy, snow-covered or slippery.

90STARTING AND OPERATING
(Continued)
Adaptive Cruise Control (ACC) Operation
The buttons on the right side of the steering wheel
operate the ACC system.
Adaptive Cruise Control Buttons (If Equipped)
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for active
driver involvement. It is always the driver’s
responsibility to be attentive of road, traffic,
and weather conditions, vehicle speed,
distance to the vehicle ahead and, most
importantly, brake operation to ensure safe
operation of the vehicle under all road condi -
tions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these warn -
ings can result in a collision and death or
serious personal injury.
The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).

Cannot take street, traffic, and weather condi -
tions into account, and may be limited upon
adverse sight distance conditions.

Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
You should not utilize the ACC system:
When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situa -
tions (i.e., in highway construction zones).
When entering a turn lane or highway
off-ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or have
steep uphill or downhill slopes.
When towing a trailer up or down steep slopes.
When circumstances do not allow safe driving
at a constant speed.

Ú
page 93.

To Set A Desired Speed
When the vehicle reaches the speed desired, push
the SET (+) button or the SET (-) button and
release. The instrument cluster display will show
the set speed.
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 98 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.
WARNING!
Leaving the Adaptive Cruise Control (ACC)
system on when not in use is dangerous. You
could accidentally set the system or cause it to
go faster than you want. You could lose control
and have a collision. Always leave the system off
when you are not using it.
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.

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.
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.

STARTING AND OPERATING95
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 canceled.
While ACC is holding your vehicle at a standstill, if
the driver tries to leave the vehicle, the parking
brake will be activated and the ACC system will be
canceled.
Display Warnings And Maintenance
RADAR SENSOR UNAVAILABILITY WARNING
The “ACC Front Radar Sensor Temporarily Blinded”
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
this warning 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 Front Radar Sensor Temporarily
Blinded” 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.
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.

100STARTING AND OPERATING
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).
For ACC system operating instructions and system
limitations, see Úpage 89.
NOTE:
The driver should always obey traffic laws and
speed limits. Never drive above applicable
speed limit restrictions.
The driver can override ADA at any time by
braking, accelerating, or steering the vehicle.
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 by
utilizing the Blind Spot Monitoring sensors.
ADA uses sensors within the steering wheel to
monitor driver attentiveness. ADA requires the
driver’s hands on the steering wheel at all times.
The system will generally aim to keep the vehicle
centered in the lane, but when the driver turns the
steering wheel (e.g. to move farther away from a
large vehicle in the next lane) the system will
reduce its control and enter "co-steering" mode.
While in co-steering mode, the system will provide
reduced assistance and allow the driver to control
the path of the vehicle. Once the driver stops
providing input to the steering wheel, the system
will require a few seconds to fully resume lane
centering assistance, especially during curves.
Do not place any objects on the steering wheel
(e.g. steering wheel covers) which could inter -
fere with the hand detection sensors.
Always pay attention to the road when using
the Active Driving Assist system. ADA will not
steer to avoid safety hazards, construction
zones, objects, or roadway impediments.
You need to maintain control to steer and
brake the vehicle in such situations and when
merging into traffic, entering the highway,
making a turn for crossing traffic, or stopping
for traffic control devices.
WARNING!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 not utilize the ADA system:
When driving in complex driving situations
(e.g. urban environments, construction zones,
etc.), adverse weather or low visibility condi -
tions (e.g. rain, snow, fog, sleet, dust), or
adverse road conditions (e.g. heavy traffic,
worn or missing lane markings, etc.).
When entering a highway on-ramp or exiting
an off-ramp, when driving on roads that are
icy, snow covered, or slippery.
When circumstances do not allow safe driving
at a constant speed.
