The buttons on the steering wheel
operate as follows:
SET +: limit speed programming
(storage of a higher speed value);
SET –: limit speed programming
(storage of a lower speed value);
RES: device activation (the actuation
of the device is signalled by the
displaying of symbol
(green on
versions with reconfigurable
multifunction display).
CANC: deactivation of the device (the
deactivation of the device is signalled by
the displaying of symbol
(white);
Automatic deactivation of device
The device deactivates automatically in
the event of fault in the system. In this
case, contact a Jeep Dealership.
ELECTRONIC CRUISE
CONTROL
DESCRIPTION
This is an electronically controlled
driving assistance device that allows the
desired vehicle speed to be maintained,
without having to press the accelerator
pedal.
This device can be used at a speed above
40 km/h on long stretches of dry, straight
roads with few variations (e.g.
motorways). It is therefore not
recommended to use this device on
extra-urban roads with traffic. Do not use
it in town.
ACTIVATING THE DEVICE
131) 132) 133)
To activate the Cruise Control press
buttonfig. 114. If the Speed Limiter
is activated, buttonmust be pressed
twice to activate the device (the first
press deactivates the Speed Limiter, the
second press activates the Cruise
Control).
For versions equipped with four wheel
drive system, the device cannot be
inserted when the 4WD LOW (ifavailable) or the Hill Descent Control
functions are activated.
The device cannot be engaged in 1
stor
reverse gear: it is advisable to engage it
in 3
rdgear or higher.
IMPORTANT It is dangerous to leave
the device on when it is not used.
There is a risk of inadvertently
activating it and losing control of the
vehicle due to unexpected excessive
speed.

DESCRIPTION
The Adaptive Cruise Control (ACC) is a
driver assist device which combines the
Cruise Control functions with one for
controlling the distance from the vehicle
ahead.
The Adaptive Cruise Control (ACC) uses a
radar sensor, located behind the front
bumper fig. 115 and a camera, located
in the middle of the windscreen fig. 116,
to detect the presence of a vehicle close
ahead.
There are two operating modes:
“Adaptive Cruise Control”mode to
maintain an adequate distance between
vehicles (the message “Adaptive CruiseControl” is shown on the instrument
panel display);
electronic “Cruise Control” modeto hold the vehicle at a constant
preset speed.
To change the operation mode, use the
button on the steering wheel (see that
described on the following pages).
ADAPTIVE CRUISE CONTROL
ACTIVATION/DEACTIVATION
Activation
To activate the device, press and release
the
button. fig. 117
The device cannot be activated when
4WD LOW is engaged.115J0A0334C
116J0A0241C117J0A0917C
163
The setting is 4 (maximum) the first time
the device is used. After the distance has
been modified by the driver, the new
distance will be stored also after the
system is deactivated and reactivated.
To decrease the distance
Press and release the
button to
decrease the distance setting.
The distance setting decreases by one
bar (shorter) every time the button is
pressed.
The set speed is held if there are no
vehicles ahead. Once the shortest
distance has been reached, a further
press of the button will set the longest
distance.
The vehicle holds the set distance until:
the vehicle ahead accelerates to a
speed higher than the set speed;
the vehicle ahead leaves the lane or
the detection field of the Adaptive Cruise
Control device sensor;
the distance setting is changed;the Adaptive Cruise Control device is
deactivated/cancelled.
IMPORTANT The maximum breaking
applied by the device is limited. The
driver may apply the brakes in all
cases, if needed.IMPORTANT If the device predicts that
the braking level is not sufficient to
hold the set distance, the warning
message “BRAKE!” will blink on the
display while approaching the vehicle
ahead. An acoustic signal is also
emitted. In this case, it is advisable to
brake immediately as necessary to hold
a safe distance from the vehicle ahead.
IMPORTANT The driver is responsible
for ensuring that there are no
pedestrians, other vehicles or
objectives along the direction of the
vehicle. Failure to comply with these
precautions may cause serious
accidents and injuries.
IMPORTANT The driver is fully
responsible for holding a safe distance
from the vehicle ahead respecting the
highway code in force in the respective
country.
DEACTIVATION
The device is deactivated and the set
speed is cancelled if:
thebutton is pressed on the
Adaptive Cruise Control;
thebutton is pressed on the
electronic Cruise Control;
the Speed Limiter button is pressed;
the ignition device is in the STOP
position;
4WD LOW mode is activated.
The device is cancelled (the set speed
and distance are stored):
when the CANC button is pressed;when the conditions shown in the
“Setting the desired speed” paragraph
occur;
when the vehicle speed drops under
the minimum set speed (e.g. in presence
of slow vehicles).
If these conditions occur while the
system is decelerating with respect to a
vehicle ahead, the system could continue
the deceleration, if necessary, also after
it is cancelled or deactivated within the
minimum speed settable on the system.
ELECTRONIC CRUISE CONTROL
MODE
Electronic Cruise Control mode is
available for travelling at constant speed
in addition to the Adaptive Cruise Control
(ACC) mode.
If the Adaptive Cruise Control (ACC)
function is implemented on the vehicle,
the electronic Cruise Control works in the
same manner as the ACC (by pressing
the
button of the Cruise Control) with
the difference that:
it does not hold the distance from the
vehicle ahead;

STARTING AND DRIVING
IMPORTANT
82)It is advisable to contact a Jeep
Dealership to have the refitting procedure
carried out. If you would like to proceed
autonomously, special attention must be
paid to the correct coupling of the
retaining clips. Otherwise, noise might be
heard due to an incorrect fastening of the
lower cover with the upper cover.
BROKEN-DOWN VEHICLE
TOWING
It is recommended to tow the vehicle
with all four wheels lifted from the
ground on the platform of a rescue
vehicle.
VERSIONS WITH FOUR-WHEEL DRIVE (4WD)
AND AUTOMATIC TRANSMISSION
IMPORTANT Avoid lifting the front (or
rear) wheels only. Lifting the front (or
rear) wheels only while towing might
damage the transmission or the
transfer unit.
IMPORTANT If a vehicle is towed
without complying with the above
requirements, the transmission and/or
the transfer unit might be seriously
damaged. Damage due to an incorrect
towing will not be covered by the
warranty.

IN AN EMERGENCY
MINIMUM GROUND CLEARANCE/TYPICAL ANGLES
"Minimum ground clearance" (reference A)
The clearance value is measured next to the lower edge of the differential. This value also defines those for the "Approach angle" the
"Departure angle" and the "Breakover angle".
Dimensions are expressed in mm and refer to the car equipped with its original tyres.
Front wheel drive (FWD) versions: 171 mm
Four-wheel drive (4WD) versions: 201 mm
Trailhawk versions with four wheel drive (4WD LOW): 225 mm
"Approach angle" (reference B )
The approach angle is determined by the horizontal line of the road surface and by the tangent line passing between the front wheel
and the most projecting low point of the car.
210J0A0242C
271
The wider the angle, the lower the chance to hit an obstacle with the body or chassis, climbing a steep slope or overcoming an
obstacle.
Front wheel drive (FWD) versions: 17.9°
Four-wheel drive (4WD) versions: 21°
Trailhawk versions with four wheel drive (4WD LOW): 30.5°
"Departure angle" (reference C)
The departure angle is determined by the same lines of the "Approach angle", and refers to the rear part of the car.
Front wheel drive (FWD) versions: 29.7°
Four-wheel drive (4WD) versions: 32.1°
Trailhawk versions with four wheel drive (4WD LOW): 34.3°
"Breakover angle" (reference D)
The value of the "Breakover angle" is linked to the ground clearance of the car and indicates the attitude of the car to overcome a
wedge, more or less steep, preventing the car from resting on the ground with the body or chassis after touching the wedge with its
lowest and most projecting parts (usually the underbody), because this would highly reduce wheel grip.
The wheels, without a suitable grip to the ground, will not have sufficient hold to move the car, and will surge.
The higher the ground clearance, the wider the breakover angle. Always bear in mind that the higher the ground clearance, the lower
the stability, due to a higher centre of gravity which reduces the side rollover angle.
Front wheel drive (FWD) versions: 21.2°
Four-wheel drive (4WD) versions: 24°
Trailhawk versions with four wheel drive (4WD LOW): 25.7°
