2023 RAM PROMASTER Owners Manual

STARTING AND OPERATING87
INTELLIGENT SPEED ASSIST (ISA) —
IF EQUIPPED
The Intelligent Speed Assist (ISA) system
combines the Active Speed Limiter and
Traffic Sign Assist (TSA) systems to
automatically adjust the maximum speed
of the vehicle based on detected traffic signs.
ACTIVATION
To activate the feature, make sure the Traffic Sign
Assist (TSA) system is enabled within Uconnect
Settings Úpage 134, then push the Active Speed
Limiter button located on the right side of the
steering wheel. The message “Ready” will appear
along with a white indicator light in the instrument
cluster display to signal that the system has been
activated.

While the system is in the “Ready” state, the driver
must press the SET (+), SET (–), or RES button to
engage the system. When the system is fully engaged
and detects the current speed limit using the TSA
system, the message in the instrument cluster display
will indicate the new detected speed limit by suggesting
the driver to press "RES" to accept it.
If the detected speed sign is greater then the
current set speed, an up arrow will be displayed
too. If the detected speed sign is lower then the
current set speed, a down arrow will be displayed
instead. If the driver accepts the new suggested
speed sign, the indicator light will change to green.
Pushing the SET (+) or SET (–) button on the right
of the steering wheel will raise and lower the set
speed to a desired value above or below the set ISA
speed. Pushing and holding down the SET (+) or
SET (–) button will increase/decrease the speed
value by increments of 5 mph (5 km/h).
NOTE:The Cruise Control (if equipped) and Adaptive
Cruise Control (if equipped) systems will be
unavailable while the ISA system is in use.
EXCEEDING THE SET SPEED
By fully pressing the accelerator pedal, the
maximum set speed can be exceeded while the
system is active.
When the maximum set speed is exceeded, the
green indicator light will blink and the instrument
cluster display will show an override message for
five seconds, or until the accelerator pedal is
released.
DEACTIVATION
To turn off the Intelligent Speed Assist system,
push the Active Speed Limiter button on the right
side of the steering wheel. A message will appear
in the instrument cluster display to confirm that the
feature has been turned off. The Intelligent Speed
Assist system can also be deactivated by pressing
the CANC button. In this case, the ISA system is
not completely turned off, and the driver can
reactivate the system by pressing the RES button.
CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control will keep your vehicle at a
constant preset speed.
Adaptive Cruise Control (ACC) will adjust the
vehicle speed up to the preset speed to main
-
tain a distance with the vehicle ahead.

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.
Cruise Control Buttons

To Activate
Push the on/off button to activate the Cruise
Control. The Cruise Indicator Light in the
instrument cluster display will illuminate. To turn
the system off, push the on/off button a second
time. The Cruise Indicator Light will turn off. The
system should be turned off when not in use.
To Set A Desired Speed
Turn the Cruise Control on. When the vehicle has
reached the desired speed, press the Cruise
Control SET (+) or SET (-) button and release.
Release the accelerator and the vehicle will
operate at the selected speed.
NOTE:The vehicle should be traveling at a steady speed
and on level ground before pressing the SET (+) or
SET (-) button.

2 — CANC/Cancel
3 — SET (-)/Decel
4 — On/Off
5 — RES/Resume
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.

23_VF_OM_EN_USC_t.book Page 88

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.

(0 km/h) when ACC is active.
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 acceler
-
ator 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.
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.

23_VF_OM_EN_USC_t.book Page 93

94STARTING AND OPERATING
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.
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 92.
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.
