NOTE
Adaptive Cruise Control (ACC) has the
ability
to override Eco cruise. This is
because ACC is designed to deceler-
ate the vehicle to match the speed of
traffic in front of the ACC equipped
truck.
transmission, or driveline), the vehicle
speed may increase until it reaches the
cruise control set speed plus the retarder
of
fset. For more information about engine
retarders, see your vehicle Operator's
Manual.
If the vehicle drops outside the speed
range, PCC will accelerate the vehicle
back to the minimum PCC speed.
As the vehicle reaches flat ground after the
hill, PCC will maintain the set-speed until
the crest of the next hill.
If the vehicle is equipped with Adaptive
Cruise Control (ACC) and senses traffic
slowing, it will overrule PCC and slow the
vehicle. This event will cancel PCC only if
the service brakes are required to slow the
vehicle. If the service brakes are not used
by ACC to maintain a safe following
distance, PCC will remain engaged and
resume automatically after the ACC event.
NOTE
PCC was calibrated using a loaded ve-
hicle.
Your results may vary, depend-
ing on your vehicle's configuration.
PCC Interrupt
There are three conditions that will
automatically deactivate PCC:
•
If there is no data for the current
road.
• If the GPS signal is lost.
• If the PCC system detects a fault.
When this happens, the vehicle will revert
to standard cruise control. This CC state
will be standard cruise control which will
maintain the same cruise speed that was
selected for PCC.
Once the system regains GPS signal and
road data, PCC will resume.
NOTE
PCC Map coverage will include most
interstate
and state highways. If you
happen to leave a supported roadway,
the PCC will deactivate. Standard
cruise control will automatically step in
to maintain the vehicle speed.
Troubleshooting
The display will show a message if it
detects an error with the PCC system.
PCC faults may result from the
unavailability of map, slope, vehicle
DRIVING - Driver Assistance
PCC Behavior
As the vehicle approaches the top of a hill,
PCC will decrease the vehicle speed (up to
8%below the set speed) to prevent the
vehicle from exceeding the set speed while
traveling downhill. This will result in a
smoother, more fuel efficient ride as the
vehicle approaches the crest of the hill.
Once over the crest, momentum takes over
and the system allows a predetermined
amount of speed over the set speed.
PCC can also activate Neutral Coast (NC)
mode. NC mode disengages the vehicle's
driveline, reducing fuel consumption while
maintaining overall vehicle speed. Once
the vehicle can no longer maintain speed
while coasting, NC is deactivated and the
driveline re-engages.
If the driver has activated one of the
vehicle's retarder systems (Engine,
