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
message “ACC DRIVER OVERRIDE” will display
in the instrument cluster display.
If you continue to accelerate beyond the set
speed while ACC is enabled, the system will not
control the distance between your vehicle and
the vehicle ahead. The vehicle speed will only be
determined by the position of the accelerator
pedal.

The Electronic Stability Control/Traction Control
System (ESC/TCS) activates
The vehicle parking brake is applied
The Trailer Sway Control (TSC) activates
The driver switches ESC to Full Off mode
The braking temperature exceeds normal range
(overheated) The following conditions will only cancel the ACC
system:
Driver seat belt is unbuckled at low speeds
Driver door is opened at low speeds
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
4WD Low is engaged
To Resume
If there is a set speed in memory, push the RES
(resume) button and then 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, 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.

154STARTING AND OPERATING
NOTE:
While in ACC mode, when the vehicle comes to
a complete stop longer than two seconds, the
system will cancel. The driver will have to apply
the brakes to keep the vehicle at a standstill.
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 incre -
ments 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 incre -
ments 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 (-) buttons, 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 applies the brake down to a full
stop when following a vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
your vehicle will release the brakes two seconds
after coming to a full stop.
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 temperature
exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for Adaptive
Cruise Control (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 displays 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.

23_DPF_OM_EN_USC_t.book Page 154

STARTING AND OPERATING155

Distance Settings

To increase the distance setting, push the
Distance Increase button and release. Each time
the button is pushed, the distance setting
increases by one bar (longer).
To decrease the distance setting, push the
Distance Decrease button and release. Each time
the button is pushed, the distance setting
decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving vehicle
is detected in the same lane, the instrument
cluster displays the ACC Set With Target Detected Indicator Light, and the system adjusts vehicle
speed automatically to maintain the distance
setting, regardless of the set speed.
NOTE:If the vehicles Integrated Trailer Brake Module
(ITBM) detects a trailer is connected to the vehicle,
and ACC is enabled, the system will increase the
distance to the longest distance setting (four bars)
by default.
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.
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
capacity.
NOTE:The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not mean that the Forward Collision
Warning system is applying the brakes autono-
mously.
Overtake Aid
When driving with 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
If the ACC system brings your vehicle to a standstill
while following a vehicle ahead, your vehicle will
resume motion, without any driver interaction, if
the vehicle ahead starts moving within two
seconds of your vehicle coming to a standstill.
If the vehicle in front does not start moving within
two seconds of your vehicle coming to a standstill,
the ACC with Stop system will cancel and the
brakes will release. A cancel message will display
on the instrument cluster display and produce a
warning chime. The driver must now manually
operate the vehicle’s accelerator and brakes.

156STARTING AND OPERATING
While ACC with Stop is holding your vehicle at a
standstill, if the driver seat belt is unbuckled or the
driver door is opened, the ACC with Stop system
will cancel and the brakes will release. A cancel
message will display on the instrument cluster
display and produce a warning chime. The driver
must now manually operate the vehicle’s
accelerator and brakes.
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC/FCW 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 “ACC/FCW Unavailable Wipe Front Radar Sensor”
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/FCW Unavailable Wipe Front Radar
Sensor” warning is active, Fixed Speed Cruise
Control is still available.
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 camera in the center of the windshield, on
the forward side of the rearview mirror.
To keep the ACC system operating properly, it is
important to note the following maintenance
items:
Always keep the sensor clean. Carefully clear
the windshield.
Do not remove any screws from the sensor.
Doing so could cause an ACC system malfunc
-
tion or failure and require a sensor realignment.
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/FCW 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 snowplow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW Limited Functionality Clean Front
Windshield” 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, driving directly into the sun and
fog on the inside of glass. In these cases, the
instrument cluster display will show “ACC/FCW
Limited Functionality Clean Front Windshield” and
the system will have degraded performance.
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.

23_DPF_OM_EN_USC_t.book Page 156

STARTING AND OPERATING157
This message can sometimes be displayed while
driving in adverse weather conditions. The ACC/
FCW 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.
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/FCW Limited Functionality Clean Front
Windshield” 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/FCW WARNING
If the system turns off, and the instrument cluster
displays “ACC/FCW Unavailable Service Required”
or “Cruise/FCW 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
NOTE:
Aftermarket add-ons such as snowplows, lift
kits, and brush/grille bars can hinder module
performance. Ensure the radar/camera has no
obstructions in the field of view.
Height modifications can limit module perfor
-
mance and functionality.
Do not put stickers or easy passes over the
camera/radar field of view.
Any modifications to the vehicle that may
obstruct the field of view of the radar/camera
are not recommended.
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
ACC while towing a trailer is recommended only
with an Integrated Trailer Brake Controller.
Aftermarket trailer brake controllers will not
activate the trailer brakes when ACC is braking.
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 decrease the vehicle speed and
acceleration for stability reasons, with no target
vehicle 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.

Stationary Object And Stationary Vehicle Example

PARKSENSE FRONT/REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Park Assist system provides visual
and audible indications of the distance between
the rear, and/or front fascia/bumper, and a
detected obstacle when backing up or moving
forward (e.g. during a parking maneuver). For
limitations of this system and recommendations,
see Ú page 162.
ParkSense will retain the system state (enabled or
disabled) from the previous ignition cycle when the
ignition is placed in the ON/RUN position.
ParkSense can be active only when the gear
selector is in REVERSE or DRIVE. If ParkSense is
enabled at one of these gear selector positions,
the system will remain active until the vehicle
speed is increased to approximately 7 mph (11 km/h) or above. A warning will appear in the
instrument cluster display when the vehicle is in
REVERSE, indicating the vehicle is above
ParkSense operating speed. The system will
become active again if the vehicle speed is
decreased to speeds less than approximately
6 mph (9 km/h).
PARKSENSE SENSORS
For the 3500, 4500 and 5500 Chassis Cab
vehicles, the rear ParkSense sensors are shipped
loose. Please refer to the Ram Body Builder’s
Guide for more information.
The four ParkSense sensors are to be located in
the rear fascia/bumper, and monitor the area
behind the vehicle that is within the sensors’ field
of view.
The sensors can detect obstacles from
approximately 12 inches (30 cm) up to 79 inches
(200 cm) from the rear fascia/bumper in the
horizontal direction, depending on the location,
type and orientation of the obstacle.
NOTE:If equipped as a dually, the ParkSense system has
six rear sensors to assist in detection around the
dually flares. The six ParkSense sensors, located in the front
fascia/bumper, monitor the area in front of the
vehicle that is within the sensors’ field of view. The
sensors can detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from
the front fascia/bumper in the horizontal direction,
depending on the location, type and orientation of
the obstacle.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen is located within
the instrument cluster display Ú
page 89. It
provides visual warnings to indicate the distance
between the rear fascia/bumper and/or front
fascia/bumper and the detected obstacle.
PARKSENSE DISPLAY
The warning display will turn on indicating the
system status when the vehicle is in REVERSE or
when the vehicle is in DRIVE and an obstacle has
been detected.
The system will indicate a detected obstacle by
showing a single arc in the left and/or right rear
regions based on the obstacle’s distance and
location relative to the vehicle.
