2019 Ram 2500 ECO mode

358 STARTING AND OPERATING
(Continued)
The Cruise Control system has two control modes:
• Adaptive Cruise Control mode for maintaining an appro-
priate distance between vehicles.
• Normal (Fixed Speed) Cruise Control mode for cruising at a constant preset speed. For additional information, refer
to “Normal (Fixed Speed) Cruise Control Mode” in this
section.
NOTE:
Normal (Fixed Speed) Cruise Control will not react to
preceding vehicles. Always be aware of the mode selected.
You can change the mode by using the Cruise Control
buttons. The two control modes function differently. Always
confirm which mode is selected.WARNING!

• Adaptive Cruise Control (ACC) is a convenience system. It is not a substitute for active driving 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 oper -
ation 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.

• 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 conditions 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.

362 STARTING AND OPERATING
To Cancel
The following conditions cancel the system:
• The brake pedal is applied.
• The CANC (cancel) button is pushed.
• An Anti-Lock Brake System (ABS) event occurs.
• The gear selector is removed from the DRIVE position.
• The Electronic Stability Control/Traction Control System(ESC/TCS) activates.
• The vehicle parking brake is applied.
• Driver seatbelt is unbuckled at low speeds.
• Driver door is opened at low speeds.
• A Trailer Sway Control (TSC) event occurs.
• The driver switches ESC to full-off mode.

• The braking temperature exceeds normal range (overheated).

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 Normal (Fixed Speed) Cruise Control on/off button is
pushed.
• The ignition is turned OFF.
• You switch to Four-Wheel Drive Low.
To Resume
If there is a set speed in memory push the RES (+) button and
then remove your foot from the accelerator pedal. The instru-
ment cluster display will display the last set speed.
NOTE:
• If your vehicle stays at standstill for longer than two seconds, the driver will have to push the RES (+) button to
reengage the ACC to the existing set speed.
• ACC cannot be resumed if there is a stationary vehicle in-front of your vehicle in close proximity.
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.

364 STARTING AND OPERATING
NOTE:
• When you override and push the RES (+) button or SET (-)buttons, the new set speed will be the current speed of the
vehicle.
• When you use the SET (-) button to decelerate, if the engine’s braking power does not slow the vehicle suffi -
ciently to reach the set speed, the brake system will auto -
matically slow the vehicle.
• The ACC system decelerates the vehicle to a full stop when following a target vehicle. If an ACC host vehicle follows a
target vehicle to a standstill, after two seconds the driver
will either have to push the RES (+) button, or apply the
accelerator pedal to reengage the ACC to the existing set
speed.
• The ACC system maintains set speed when driving up hill and down hill. 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 up hill and down hill, the ACC system will
cancel if the braking temperature 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 calcu-
lates and sets the distance to the vehicle ahead. This distance
setting displays in the instrument cluster display.
Distance Setting 4 Bars (Longest)

STARTING AND OPERATING 369
Adaptive Cruise Control Set
When the RES (+) or the SET(-) button (located on the
steering wheel) is pushed, the display will read “ACC SET.”
When ACC is set, the set speed will show in the instrument
cluster display.
The ACC screen may display once again if any ACC activity
occurs, which may include any of the following:
• System Cancel
• Driver Override
• System Off
• ACC Proximity Warning
• ACC Unavailable WarningThe instrument cluster display will return to the last
display selected after five seconds of no ACC display
activityDisplay 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.
