JEEP GRAND CHEROKEE 2013 WK2 / 4.G Owners Manual

WARNING!
•Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driving
involvement. It is always the driver ’s responsibil-
ity to be attentive of road, traffic, and weather
conditions, vehicle 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 re-
quired while driving to maintain safe control of
your vehicle. Failure to follow these warnings can
result in a collision and death or serious personal
injury.
•The ACC system:
– Does not react to pedestrians, oncoming ve-
hicles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
(Continued)
WARNING!(Continued)
– Cannot take street, traffic, and weather condi-
tions into account, and may be limited upon
adverse sight distance conditions.
– Does not predict the lane curvature or the move-
ment of preceding vehicles and will not compen-
sate for such changes.
– Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.
– Can only apply a maximum of 25% of the vehi-
cle’s braking capability, and will not bring the
vehicle to a complete stop.

WARNING!
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 construction zones).
•When entering a turn lane or highway off ramp;
when driving on roads that are winding, 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.
Failure to follow these warnings can result in a
collision and death or serious personal injury.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:The system 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 selected.
Adaptive Cruise Control (ACC) Operation
The speed control buttons (located on the right side of the
steering wheel) operates the ACC system.

18 mph (30 km/h).
When the system is turned on and in the READY state,
the Electronic Vehicle Information Center (EVIC) dis-

WARNING!
The Resume function should only be used if traffic
and road conditions permit. Resuming a set speed
that is too high or too low for prevailing traffic and
road conditions could cause the vehicle to accelerate
or decelerate too sharply for safe operation. Failure to
follow these warnings can result in a collision and
death or serious personal injury.
To Vary The Speed Setting
While ACC is set, you can increase the set speed by
pressing and holding the RES+button. If the button is
continually pressed, the set speed will continue to in-
crease in 5 mph (10 km/h) increments until the button is
released. The increase in set speed is reflected in the EVIC
display.Pressing the RES+button once will result ina1mph
(1 km/h) increase in set speed. Each subsequent tap of
the button results in an increase of 1 mph (1 km/h).
While ACC is set, the set speed can be decreased by
pressing and holding the SET-button. If the button is
continually pressed, the set speed will continue to de-
crease in 5 mph (10 km/h) increments until the button is
released. The decrease in set speed is reflected in the
EVIC display.
Pressing the SET-button once will result ina1mph
(1 km/h) decrease in set speed. Each subsequent tap of
the button results in a decrease of 1 mph (1 km/h).
NOTE:
•When you use the SET-button to decelerate, if the
engine’s braking power does not slow the vehicle
sufficiently to reach the set speed, the brake system
will automatically slow the vehicle.
226 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•The ACC system can only apply a maximum of 25% of
the vehicle’s braking capability and will not bring the
vehicle to a complete stop.
•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 down-
hill. This is normal operation and necessary to main-
tain set speed.
Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between 3 (long), 2 (me-
dium), and 1 (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.Distance Setting 3
