Jeep Grand Cherokee SRT 2018 Owner's Manual page 155

NOTE:
• If the sensor does not detect a vehicle ahead
of you, ACC will maintain a fixed set speed.
• If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or accelerate
(not to exceed the original set speed) auto-
matically to maintain a preset following dis-
tance, while matching the speed of the ve-
hicle ahead.
The Cruise Control system has two control
modes:
• Adaptive Cruise Control mode for maintaining
an appropriate 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 se-
lected.

WARNING!
• Adaptive Cruise Control (ACC) is a conve-
nience 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, ve-
hicle speed, distance to the vehicle ahead;
and, most importantly, brake operation 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 colli-
sion 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 con-
ditions.
• Does not always fully recognize com-
plex driving conditions, which can result
in wrong or missing distance warnings.

WARNING! (Continued)
• Will bring the vehicle to a complete stop
while following a target vehicle and hold
the vehicle for 2 seconds in the stop
position. If the target vehicle does not
start moving within 2 seconds, the ACC
system will display a message that the
system will release the brakes and that
the brakes must be applied manually. An
audible chime will sound when the
brakes are released.
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway construc-
tion zones).
• When entering a turn lane or highway off
ramp; when driving on roads that are wind-
ing, icy, snow-covered, slippery, or have
steep uphill or downhill slopes.
• When towing a trailer up or down steep
slopes.
• When circumstances do not allow safe
driving at a constant speed.
