Predictive Adaptive Cruise Control — if
equipped with adaptive cruise control (ACC),
allows IPM to increase following distance
IMPORTANT: IPM behavior is different from that of
conventional cruise control. The system incorporates
features to improve the overall driver experience.
Some key points to remember are:
•
IPM is active only when cruise control is en-
gaged.
•
IPM only controls speed within the upper and
lower bounds of the cruise set speed. The
upper and lower set limits may be exceeded
up to 2 mph (3 km/h) for a limited time during
dip coasts, as IPM predicts the terrain de-
mands for the most fuel-efficient performance.
The driver is responsible for setting a speed
appropriate for the conditions and grade. If
equipped, IPM upper and lower bounds can be
adjusted by selecting the quick access button
on the steering wheel.
•
IPM can engage eCoast sooner, later, or not at
all compared to conventional cruise control.
•
IPM may automatically engage the engine
brake at a higher speed than the cruise set
speed.
•
If IPM becomes unavailable, conventional
cruise control can still function.
WARNING
Apply the brakes and downshift as necessary
when driving on downhill grades. IPM does not
adequately control vehicle speed on steep down-
hill grades. Failure to use normal braking tech-
niques when IPM is active could result in per-
sonal injury and vehicle damage.
IMPORTANT: IPM adjusts the vehicle set speed
to achieve maximum fuel economy, but it does
not account for traffic flows or surrounding ve-
hicles.
For best fuel-savings, use cruise control whenever
possible. Driver interaction with IPM is the same as
conventional cruise control, using the standard cruise
control buttons. In the event of a problem with IPM,
or when driving on a road with no profile information
available, the system reverts to conventional cruise
control.
Using the accelerator pedal will abort the current IPM
use case. Disengaging the cruise control will also
disengage IPM.
Descent Control and Deceleration
Modes, Detroit
™
Engines
On vehicles equipped with a Detroit engine, the func-
tions of the engine brake controls change, depending
on which specialty braking mode is being utilized.
Two distinct modes can be activated:
•
Descent Control Mode—engine braking at-
tempts to maintain a set speed; accelerator
pedal is not automatically applied.
•
Deceleration Mode—engine braking activates
to reduce vehicle speed (with no lower limit) at
a constant rate.
Descent Control Mode
Descent Control Mode attempts to keep the vehicle
speed at the set speed on a downhill, using all avail-
able engine brake stages.
To activate Descent Control Mode, exit cruise control,
remove your foot from the accelerator pedal, set the
engine brake in any of the 3 "on" positions (positions
1, 2, or 3 in
), and use the set or resume
buttons to set the vehicle speed. In this mode, all
three levels of engine braking will be employed to
keep the speed below the set speed. This mode will
not keep the speed above the lower limit of the set
speed, so it is possible to eventually coast to a stop,
unless the lever is moved to "engine brake off" (posi-
tion 0), or the accelerator pedal is applied. After ac-
celerator pedal application, the Descent Control
Mode is resumed. In the case of very steep road
grades, the engine brake may not be able to main-
tain the vehicle speed. The driver may apply the ser-
vice brakes without dropping out of descent mode to
slow the vehicle speed down slower than their set
speed. After releasing the service brakes, a new
cruise set speed lower than the original set speed
will be set. A message in the instrument panel will
inform the driver a new set speed was captured.
Decreasing the lever to the 0 position deactivates
Descent Control Mode and resumes cruise control,
using the Descent Control set speed as the cruise
control set speed. To reactivate Descent Control
Mode, reset the control speed with the lever in posi-
tion 1, 2, or 3.
An indicator on the driver display illuminates when
descent control mode is active. See
