2020 Ram 1500 front

STARTING AND OPERATING 327
NOTE:
Automatic Aero Mode may be disabled through vehicle
settings on your Uconnect Radio.
•Entry/Exit Mode (Lowers the vehicle approximately
3 inches (73 mm)) – This position lowers the vehicle for
easier passenger entry and exit as well as lowering the
rear of the vehicle for easier loading and unloading of
cargo. To enter Entry/Exit Mode, push the height
selector switch down twice from the NRH while the
vehicle speed is below 33 mph (53 km/h). Once the
vehicle speed goes below 15 mph (24 km/h) the vehicle
height will begin to lower. If the vehicle speed remains
between 15 mph (24 km/h) and 25 mph (40 km/h) for
greater than 60 seconds, or the vehicle speed exceeds
25 mph (40 km/h) the Entry/Exit change will be
cancelled. To return to Normal Height Mode, push the
height selector switch up twice while in Entry/Exit or
drive the vehicle over 15 mph (24 km/h). Entry/Exit
mode may not be available due to vehicle payload, an
instrument cluster display message will be shown when
this occurs.
Refer to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information. The system requires that the ignition be in the ON/RUN
position or the engine running for all user requested
changes. When lowering the vehicle all of the doors, must be
closed. If a door is opened at any time while the vehicle is
lowering the change will not be completed until the open
door(s) is closed.
This system uses a lifting and lowering pattern which keeps
the headlights from incorrectly shining into oncoming
traffic. When raising the vehicle, the rear of the vehicle will
move up first and then the front. When lowering the vehicle,
the front will move down first and then the rear.
After the engine is turned off, it may be noticed that the air
suspension system operates briefly, this is normal. The
system is correcting the position of the vehicle to ensure a
proper appearance.CAUTION!
When in ENTRY/EXIT setting, be aware of your
surroundings, you may not have the clearance required
for certain areas and vehicle damage may occur.

• 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 Speed
While ACC is set, you can increase the set speed by pushing
the SET (+) button.
The speed increment shown is dependent on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the SET (+) button once will result in a 1 mph
increase in set speed. Each subsequent tap of the button
results in an increase of 1 mph.
• If the button is continually pushed, the set speed will continue to increase in 5 mph increments until the button
is released. The increase in set speed is reflected 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.

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 also a chime will indicate 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.
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in highly
reflective areas (i.e. tunnels with reflective tiles, or ice and
snow). 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 Normal (Fixed Speed) Cruise Control is
still available. For additional information refer to “Normal
(Fixed Speed) Cruise Control Mode” in this section.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 wind
-
shield.
• Do not remove any screws from the sensor. Doing so could cause an ACC system malfunction or failure and require a
sensor realignment.
• Do not attach or install any accessories near the sensor, including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or malfunc -
tion.
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 reac -
tivating it.

354 STARTING AND OPERATING
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 your authorized dealer.
• Installing a snow plow, front-end protector, an after -
market 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 Wind -
shield” warning will display and also a chime will indicate
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.
The “ACC/FCW Limited Functionality Clean Front Wind -
shield” 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 rear view 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 Wind
-
shield” message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other obstruc -
tion, have the windshield and forward facing camera
inspected at your 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 unavail -

PARKSENSE FRONT AND REAR PARK ASSIST
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear and/or
front fascia and a detected obstacle when backing up or
moving forward (e.g. during a parking maneuver). If your
vehicle is equipped with the automatic braking function, the
vehicle brakes may be automatically applied and released
when performing a reverse parking maneuver if the system
detects a possible collision with an obstacle.

2020_DT_1500_OM_US.book Page 361

STARTING AND OPERATING 363
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 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

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.
The four ParkSense sensors, located in the rear fascia/
bumper, 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.

ParkSense Warning Display
The ParkSense Warning screen is located within the instru-
ment cluster display. It provides visual warnings to indicate
the distance between the rear fascia/bumper and/or front
fascia/bumper and the detected obstacle. Refer to “Instru-
ment Cluster Display” in “Getting To Know Your Instru-
ment Panel” for further information.
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, right, or center regions based on the
obstacle’s distance and location relative to the vehicle.
If an obstacle is detected in the left, right, or center regions,
the display will show a single arc in the left and/or right
regions and the system will produce a tone. As the vehicle
moves closer to the obstacle, the display will show the single
arc moving closer to the vehicle and the tone will change
from a single 1/2 second tone to slow, to fast, to continuous.5
