Jeep Grand Cherokee 2015, Operating Information Manual, Page: 111 / 878

Metric Speed (km/h)
•
Pressing the SET - button once will result in
a 1 km/h decrease in set speed. Each sub-
sequent tap of the button results in a de-
crease of 1 km/h.
•
If the button is continually pressed, the set
speed will continue to decrease in 10 km/h
increments until the button is released. The
decrease in set speed is reflected in the
EVIC/DID.
NOTE:
•
When you override and push the SET +
button or SET - buttons, the new Set
Speed will be the current speed of the
vehicle.
•
When you use the SET - button to decel-
erate, if the engine’s braking power does
not slow the vehicle sufficiently 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
press the RES (resume) 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. How-
ever, a slight speed change on moderate
hills is normal. In addition, downshifting
may occur while climbing uphill or de-
scending downhill. This is normal opera-
tion 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 (me-
dium) and one bar (short). Using this distance
setting and the vehicle speed, ACC calculates
and sets the distance to the vehicle ahead. This
distance setting displays in the EVIC/DID.
Distance Setting 4 Bars (Longest)
Distance Setting 3 Bars (Long)
