2019 RAM CHASSIS CAB ECO mode

STARTING AND OPERATING 295
• 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) 5

300 STARTING AND OPERATING
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

activity
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.

Measuring Height (H)
3. Attach the trailer to the vehicle without the weight distri -
bution bars connected.
4. Measure the height of the top of the front wheel opening
on the fender to ground, this is height H2.
5. Install and adjust the tension in the weight distributing
bars per the manufacturers’ recommendations so that the
height of the front fender is approximately (H2-H1)/
2+H1 (about 1/2 the difference between H2 and H1 above
normal ride height [H1]). 6. Preform a visual inspection of the trailer and weight
distributing hitch to confirm manufacturers’ recommen -
dations have been met.
NOTE:
For all towing conditions, we recommend towing with tow
haul mode engaged.
