2022 RAM PROMASTER stop start

STARTING AND OPERATING77
When frequent transmission shifting occurs (such
as when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong
head winds, or while towing a heavy trailer), select
TOW/HAUL mode or use the Electronic Range
Select (ERS) shift control to select a lower gear
range Úpage 77. Under these conditions, using a
lower gear range will improve performance and
extend transmission life by reducing excessive
shifting and heat buildup.
During cold temperatures, transmission operation
may be modified depending on engine and
transmission temperature as well as vehicle
speed. This feature improves warm-up time of the
engine and transmission to achieve maximum
efficiency. During extremely cold temperatures
(-16°F [-27°C] or below), operation may briefly be
limited to THIRD gear only. Normal operation will
resume once the transmission temperature has
risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home Mode is activated. In this
mode, the transmission remains in THIRD gear
regardless of which forward gear is selected.
PARK, REVERSE, and NEUTRAL will continue to operate. The Malfunction Indicator Light (MIL) may
be illuminated. Transmission Limp Home Mode
allows the vehicle to be driven to an authorized
dealer for service without damaging the
transmission.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the
transmission will return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission. If the transmission
cannot be reset, authorized dealer service is
required.
Electronic Range Select (ERS) Operation
The ERS shift control allows the driver to
select the max gear limit. For example, if you
set the transmission gear limit to FOURTH gear, the
transmission will not shift above FOURTH gear, but
will shift through the lower gears normally.
You can switch between DRIVE and ERS mode at
any vehicle speed. When the gear selector is in the
DRIVE position, the transmission will operate
automatically, shifting between all available gears.
Moving the gear selector to the ERS position
(beside DRIVE) will activate ERS mode, display the
current gear in the instrument cluster, and set that
gear as the max gear limit. Once in ERS mode,
moving the gear selector forward “-” or rearward
“+” will change the max gear limit.
NOTE:The transmission will still continue to use the
optimal highest gear, for the current driving condi -
tions, within the selected gear range limit.
To exit ERS mode, simply return the gear selector
to the DRIVE position.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.

82STARTING AND OPERATING
(Continued)
To Accelerate For Passing
While the Cruise Control system 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 80.
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 256.
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!
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).

22_VF_OM_EN_USC_t.book Page 82

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.

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.
Stationary Object And Stationary Vehicle Example

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.
Active Driving Assist Indicators Are Green
System is actively steering the vehicle and the
system detects driver is attentive.
Active Driving Assist Indicators Are Yellow
Driver inattentiveness has been detected,
warning the driver to place hands on the
steering wheel.
Active Driving Assist Indicators Are Red
Driver inattentiveness is still being detected,
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

96STARTING AND OPERATING
SYSTEM OPERATION/LIMITATIONS
The Active Driving Assist system DOES NOT:
Warn or prevent collisions with other vehicles
Steer your vehicle around stopped vehicles,
slower vehicles, construction equipment,
pedestrians, or animals
Respond to traffic lights or stop signs
Merge onto highways or exit off ramps
Turn your vehicle
Change lanes
React to cross traffic The Active Driving Assist system may have limited
or reduced functionality when one of the following
conditions occur:
The vehicle’s radar sensors and/or forward
facing camera is damaged, covered, or
obstructed (e.g. by mud, ice, snow, etc.)
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.

22_VF_OM_EN_USC_t.book Page 96

102STARTING AND OPERATING
If it is necessary to keep the ball mount and hitch
ball assembly mounted for a long period, it is
possible to filter out the ball mount and hitch ball
assembly presence in the sensor field of view.
The filtering operation must be performed only by
an authorized dealer.
LANESENSE — IF EQUIPPED
LANESENSE OPERATION

The LaneSense system is operational at speeds above
37 mph (60 km/h) and below 112 mph (180 km/h).
The LaneSense system uses a forward looking camera
to detect lane markings and measure vehicle position
within the lane boundaries.

When both lane markings are detected and the
driver drifts out of the lane (no turn signal applied),
the LaneSense system provides a haptic warning
in the form of torque applied to the steering wheel,
as well as a visual warning in the instrument
cluster display, to prompt the driver to remain
within the lane boundaries.
The driver may manually override the haptic
warning by applying force to the steering wheel at
any time.

When only a single lane marking is detected and the
driver drifts across the lane marking (no turn signal
applied), the LaneSense system provides a visual
warning through the instrument cluster display to
prompt the driver to remain within the lane.

WARNING!
Drivers must be careful when backing up even
when using ParkSense. Always check carefully
behind your vehicle, look behind you, and be
sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before
backing up. You are responsible for safety and
must continue to pay attention to your
surroundings. Failure to do so can result in
serious injury or death.

Before using ParkSense, it is strongly recom -
mended that the ball mount and hitch ball
assembly be disconnected from the vehicle
when the vehicle is not used for towing. Failure
to do so can result in injury or damage to vehi -
cles or obstacles because the hitch ball will be
much closer to the obstacle than the rear fascia
when the vehicle sounds the continuous tone.
Also, the sensors could detect the ball mount
and hitch ball assembly, depending on its size
and shape, giving a false indication that an
obstacle is behind the vehicle.

CAUTION!

ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obsta -
cles. Parking curbs might be temporarily detected
or not detected at all. Obstacles located above or
below the sensors will not be detected when they
are in close proximity.

The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time
when an obstacle is detected. It is recom -
mended that the driver looks over his/her
shoulder when using ParkSense.
