Jeep GRAND CHEROKEE 2023 Owner's Manual page 136

To increase the distance setting, push the Distance
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
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 instrument cluster display will show the
ACC Set With Target Detected Indicator Light, and the
system will adjust the vehicle speed automatically 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.
 The distance setting is changed.
 The system disengages page 132.
Ú
The maximum braking applied by ACC is limited; however,
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 instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity.
NOTE:
The "BRAKE!" screen in the instrument cluster display is a
warning for the driver to take action and does not neces-
sarily mean that the Forward Collision Warning system is
applying the brakes autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (ACC) engaged
and following a vehicle, the system will provide an
additional acceleration up to the ACC set speed to assist
in passing the vehicle. In locations with left hand drive
traffic, an additional acceleration is triggered when the
driver utilizes the left turn signal and will only be active
when passing on the left hand side. In locations with right
hand drive traffic, an additional acceleration is triggered
when the driver utilizes the right turn signal and will only
be active when passing on the right hand side.
NOTE:
When the vehicle transitions from a location with left hand
drive traffic to a location with right hand drive traffic or vice
versa, the ACC system will automatically detect the
direction of traffic.
STARTING AND OPERATING
ACC Operation At Stop
If the ACC system brings your vehicle to a standstill while
following a vehicle ahead, your vehicle will resume motion,
without any driver interaction, if the vehicle ahead starts
moving within two seconds of your vehicle coming to a
standstill.
If the vehicle in front does not start moving within two
seconds of your vehicle coming to a standstill, the driver
will either have to push the RES (resume) button, or apply
the accelerator pedal to reengage the ACC to the existing
set speed.
NOTE:
 If your vehicle is at a standstill for longer than two
seconds, the system will hold brake pressure for up to
10 minutes. If no driver action is taken after the
10 minutes, the Electric Park Brake will be applied and
the ACC system will cancel.
 While ACC is holding your vehicle at a standstill, or the
vehicle is traveling below 3 mph (5 km/h) and the
driver seat belt is unbuckled or the driver door is
opened, the Electric Park Brake will be applied and the
ACC system will cancel.
