2016 JEEP GRAND CHEROKEE Owners Manual

•The gear selector is removed from the Drive position.
• The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.
• The vehicle parking brake is applied.
• Driver seatbelt is unbuckled at low speeds.
• Driver door is opened at low speeds.
• A Trailer Sway Control (TSC) event occurs.
To Turn Off
The system will turn off and clear the set speed in
memory if:
•The Adaptive Cruise Control (ACC) ON/OFF button
is pushed.
• The Normal (Fixed Speed) Electronic Speed Control
ON/OFF button is pushed. •
The ignition is turned OFF.
• You switch to Four-Wheel Drive Low.
To Resume
If there is a set speed in memory push the RES (resume)
button and then remove your foot from the accelerator
pedal. The DID will display the last set speed.
NOTE:
•If your vehicle stays at standstill for longer than two
seconds, then the system will cancel and the brake
force will be ramped-out. The driver will have to apply
the brakes to keep the vehicle at a standstill.
• ACC cannot be resumed if there is a stationary vehicle
in-front of your vehicle in close proximity.3

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
To Increase Speed
While ACC is set, you can increase the set speed by
pushing the SET+button.
The drivers preferred units can be selected through the
instrument panel settings if equipped. Refer to “Under-
standing Your Instrument Panel” for more information. The speed increment shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
•
Pushing the SET +button once will result ina1mph
increase in set speed. Each subsequent tap of the
button results in an increase of 1 mph.
• If the button is continually pushed, the set speed will
continue to increase in 5 mph increments until the
button is released. The increase in set speed is reflected
in the DID.
Metric Speed (km/h)
• Pushing the SET +button once will result in a 1 km/h
increase in set speed. Each subsequent tap of the
button results in an increase of 1 km/h.
200 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•If the button is continually pushed, the set speed will
continue to increase in 10 km/h increments until the
button is released. The increase in set speed is reflected
in the DID.
To Decrease Speed
While ACC is set, the set speed can be decreased by
pushing the SET -button.
The drivers preferred units can be selected through the
instrument panel settings if equipped. Refer to “Under-
standing Your Instrument Panel” for more information.
The speed decrement shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the SET -button once will result ina1mph
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 mph. •
If the button is continually pushed, the set speed will
continue to decrease in 5 mph decrements until the
button is released. The decrease in set speed is re-
flected in the DID.
Metric Speed (km/h)
• Pushing the SET -button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 km/h.
• If the button is continually pushed, the set speed will
continue to decrease in 10 km/h decrements until the
button is released. The decrease in set speed is re-
flected in the 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 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.
• The ACC system applies the brake down to a full stop
when following a target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill, the host vehicle
will release the vehicle brakes two seconds after com-
ing to a full 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. 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 (medium) 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 DID.
Distance Setting 4 Bars (Longest)
202 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Distance Setting 3 Bars (Long)Distance Setting 2 Bars (Medium)

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 203

To increase the distance setting, push the Distance Setting
— Increase button and release. Each time the button is
pushed, the distance setting increases by one bar (longer).To decrease the distance setting, push the Distance Set-
ting — Decrease button and release. Each time the button
is pushed, the distance setting decreases by one bar
(shorter).
If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in the
same lane, the DID displays the “Sensed Vehicle Indica-
tor” icon, and the system adjusts vehicle speed automati-
cally to maintain the distance setting, regardless of the set
speed.
The vehicle will then maintain the set distance until:
•
The vehicle ahead accelerates to a speed above the set
speed.
• The vehicle ahead moves out of your lane or view of
the sensor.
Distance Setting 1 Bar (Short)
204 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•The distance setting is changed.
• The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE: The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to
maintain the set distance. If this occurs, a visual alert
“BRAKE” will flash in the DID and a chime will sound
while ACC continues to apply its maximum braking
capacity. NOTE:
The “Brake!” Screen in the DID is a warning for
the driver to take action and does not necessarily mean
that the Forward Collision Warning system is applying
the brakes autonomously.

Overtake Aid
When driving with ACC engaged and following a ve-
hicle, the system will provide an additional acceleration
up to the ACC set speed to assist in passing the vehicle.
This additional acceleration is triggered when the driver
utilizes the left turn signal and will only be active when
passing on the left hand side.
ACC Operation At Stop
If the ACC system brings your vehicle to a standstill
while following a target vehicle, if the target vehicle starts
moving within two seconds of your vehicle coming to a
standstill, your vehicle will resume motion without the
need for any driver action.
If the target vehicle does not start moving within two
seconds of your vehicle coming to a standstill, the ACC
with Stop system will cancel and the brakes will release.A cancel message will display on the DID and produce a
warning chime. Driver intervention will be required at
this moment.
While ACC with Stop is holding your vehicle at a
standstill, if the driver seatbelt is unbuckled or the driver
door is opened, the ACC with Stop system will cancel
and the brakes will release. A cancel message will display
on the DID and produce a warning chime. Driver inter-
vention will be required at this moment.
WARNING!
When the ACC system is resumed, the driver must
ensure that there are no pedestrians, vehicles or
objects in the path of the vehicle. Failure to follow
these warnings can result in a collision and death or
serious personal injury.
