The speed set for the HDC system can be
adjusted using the brake pedal and the
accelerator pedal (in the 1-12 km/h
range). Once the desired speed is
reached, when both pedals are released
the HDC system will maintain the set
speed. In this way, the driver can adjust
the speed and, if necessary, reassume
control of the vehicle.
If the vehicle speed exceeds 12 km/h but
it is lower than 40 km/h, when both
pedals are released, the HDC system will
return the vehicle speed to 12 km/h.
With gear lever in neutral, speed
adjustment using the accelerator pedal is
not available.
The driver can cancel the intervention of
the HDC system at any time by
completely depressing the accelerator
pedal or the brake pedal.
System deactivation
The HDC system is deactivated, but
remains available, if one of the following
conditions is met:
the vehicle is on a descent with
insufficient gradient, below 8%, or a
level surface, or is going uphill;
the gear lever is in P (Park) position.Disabling the system
The system is deactivated and disabled if
one of the following conditions is met:
fig. 70 button pressed;activation of mode other than 4WD
LOW;
electric parking brake (EPB)
engagement;
driver side door open;speed of 40 km/h exceeded
(immediate exit from HDC function).
DISABLING ACTIVE SAFETY
SYSTEMS
Depending on the versions, there are
3 configurations for the active safety
systems on the vehicle:
systems enabled;systems partially disabled;systems disabled.
Systems enabled
All active safety systems are enabled.
This is the normal operating mode when
driving a four-wheel-drive vehicle.
This mode should be used in most
driving conditions. The system will be in
"Systems enabled" mode every time the
engine is started.
IMPORTANT You are advised to select
"Systems partially disabled" or "Systems
disabled" modes only for specific driving
requirements.Systems partially disabled
By pressing the
button on the central
tunnel fig. 71 for fewer than 5 seconds
when driving, the TSC system can be
disabled and the intervention of the TC
system can be limited to braking action
on the individual drive wheels. The other
systems remain enabled.
Activation of this mode is indicated by
the
warning light on the instrument
panel switching on (on some versions,
together with a message on the display).
To restore "All systems enabled"
operating mode, press the button on the
central tunnel again.
"Systems completely enabled" mode will

SAFETY
automatically reactivate every time the
engine is started.
IMPORTANT When travelling on snowy
roads with snow chains, it may be helpful
to activate "Systems partially disabled"
mode: in these conditions, slipping of
the drive wheels when moving off makes
it possible to obtain better traction.
Systems disabled
Pressing the
button on the central
tunnel for more than 5 seconds
completely deactivates the ESC system,
as well as the TSC and ERM systems; the
TC system will be limited to braking
action on the individual drive wheels.
The other systems remain enabled.
Activation of this mode is highlighted by
the
warning light on the instrument
panel switching on (on some versions,
together with a message on the display).
IMPORTANT If a speed of approximately
65 km/h is exceeded, the systems will
behave as described for "Systems
partially disabled" mode.
To restore "Systems enabled" operating
mode, press the button on the central
tunnel again.
"Systems enabled" mode will
automatically reactivate every time the
engine is started.Versions with Selec-Terrain™ device
On versions withSelec-Terrain™device,
the activation of certain driving modes
partially or totally deactivates certain
active safety systems in order to optimise
performance in the specific mode.
When active safety systems are partially
or totally deactivated, the
warning light
will turn on in the instrument panel.
In "SAND" and "MUD" modes, the active
safety systems are partially disabled and
fine-tuned to ensure maximum
performance in the specific operating
modes. It is in any case possible to
reactivate them completely at any time
by pressing the
button on the central
tunnel should you wish to favour safety
over "off-road" performance.
IMPORTANT In 4WD LOW modes, the
active safety systems are completely
disabled in order to ensure maximum
off-road driving performance and it will
not be possible to reactivate them.

WARNING
36)When the ABS intervenes and you feel
the brake pedal pulsating, do not reduce
the pressure, but hold it down firmly and
confidently; in doing so you will brake in
the shortest distance possible, depending
on the current road conditions.
37)To obtain the maximum efficiency of
the braking system, a bedding-in period of
about 500 km is needed: during this
period it is better to avoid sharp, repeated
and prolonged braking.
38)If the ABS intervenes, this indicates
that the grip of the tyres on the road is
nearing its limit: you must slow down to a
speed compatible with the available grip.
39)The ABS cannot overrule the natural
laws of physics, and cannot increase the
grip available according to the condition
of the road.
40)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
41)The capability of the ABS must never
be tested irresponsibly and dangerously,
in such a way as to compromise personal
safety and the safety of others.
105
42)For the correct operation of the ABS,
the tyres must of necessity be the same
make and type on all wheels, in perfect
condition and, above all, of the prescribed
type and dimensions.
43)The ESC system cannot alter the
natural laws of physics, and cannot
increase grip, which depends on the
condition of the road.
44)The ESC system cannot prevent
accidents, including those due to
excessive speed on corners, driving on
low-grip surfaces or aquaplaning.
45)The capability of the ESC system must
never be tested irresponsibly and
dangerously, in such a way as to
compromise personal safety and the safety
of others.
46)For the correct operation of the ESC
system, the tyres must necessarily be of
the same make and type on all wheels, in
perfect condition and, above all, of the
prescribed type and size.
47)ESC performance features must not
induce the driver to take unnecessary or
unwarranted risks. Your driving style must
always be suited to the road conditions,
visibility and traffic. The driver is, in any
case, responsible for safe driving.48)For the correct operation of the TC

must never be tested irresponsibly and
dangerously, in such a way as to
compromise the safety of the driver, the
other occupants of the vehicle or any other
road user.
56)The Hill Start Assist system is not a
parking brake; therefore, never leave the
vehicle without having engaged the
electric parking brake, turned the engine
off and engaged first gear, so that it is
parked in safe conditions (for further
information read the "Parking" paragraph
in the "Starting and driving" chapter).
57)There may be situations on small
gradients (less than 8%), with vehicle
laden, in which the Hill Start Assist
system may not activate, causing a slight
reversing motion and increasing the risk of
collision with another vehicle or object.
The driver is, in any case, responsible for
safe driving.
58)DST is an aid for driving and does not
relieve the driver of responsibility for
driving the vehicle.
59)The performance of a vehicle with
ERM must never be tested in imprudent or
dangerous ways, with the possibility of
putting the safety of the driver or other
people at risk.
106
SAFETY
60)When towing trailers, the utmost
caution at the wheel is recommended.
Never exceed the maximum permitted
loads (see the description in the "Weights"
paragraph in the "Technical
Specifications" chapter).
61)The TSC system cannot prevent
swerving for all trailers. If the system
activates during driving, reduce the speed,
stop the vehicle in a safe place and
arrange the load correctly to prevent the
trailer from swerving.
62)Prolonged use of the system may
overheat the braking system. If the brakes
overheat, the HDC system, when active,
will be gradually deactivated after suitably
informing the driver (LED on button off): it
can be reactivated only when the brakes
have cooled sufficiently. The distance that
can be covered depends on the
temperature of the brakes and therefore
on the gradient, load and speed of the
vehicle.
63)The performance of a vehicle with
HDC must never be tested in imprudent or
dangerous ways, with the possibility of
putting the safety of the driver or other
people at risk.64)When "Systems partially disabled"
mode is selected, the intervention of the
TC function is limited to braking action on
the individual drive wheels and the
warning light switches on in the
instrument panel. In "systems partially
disabled" mode, the engine torque value
that the ESC system may require will not
be guaranteed and the stability of the
vehicle will therefore be reduced.
65)With "Systems partially disabled"
mode selected, the TSC (Trailer Sway
Control) system is disabled.
66)Your driving style must always be
suited to the road conditions, visibility and
traffic. The driver is, in any case,
responsible for safe driving.
67)When "Systems disabled" mode is
selected, the ESC system will not be
available in the event of emergency
manoeuvres. "Systems disabled" mode is
only for off-road use.
107
AUXILIARY DRIVING
SYSTEMS
BSM (Blind Spot Monitoring)
SYSTEM
(where provided)
The system uses two radar sensors,
located in the rear bumper (one for each
side - see fig. 72) to detect the presence
of vehicles (cars, trucks, motorbikes,
etc.) in the rear side blind spots of the
vehicle.
The system warns the driver about the
presence of cars in the detection area by
lighting up, on the relevant side, the
warning light located on the door mirror
fig. 73, along with an acoustic warning.
When the ignition device is in MAR
position, or when the engine is started,the warning light turns on to signal the
driver that the system is active.
Sensors
The sensors are activated by shifting to
any forward gear at a speed higher than
about 10 km/h, or when reverse is
engaged. The sensors are temporarily
deactivated with vehicle at a standstill
and the gear lever in position P (Park)
(versions with automatic transmission),
or with vehicle at a standstill and electric
parking brake engaged (versions with
manual gearbox).
The detection area of the system covers
about a lane on both sides of the vehicle
(around 3 metres). This area begins from
72J0A0921C
73J0A0217C
108
SAFETY
an obstacle has been detected is
activated, an acoustic warning is emitted
as well. When the acoustic warning is
emitted, theUconnect™volume is
lowered.
"Blind spot alert" function deactivation:
When the system is deactivated ("Blind
spot alert" mode at "OFF"), the BSM or
RCP systems will not emit neither
acoustic nor visual warnings. The BSM
system will store the operating mode
running when the engine was switched
off: each time the engine is started, the
operating mode stored previously will be
recalled and used.
FORWARD COLLISION WARNING
PLUS SYSTEM
69) 70) 71) 72)
33) 34) 35) 36) 37) 38) 39) 40) 41)
It consists of a radar located behind the
front bumper fig. 74 and a camera
located in the middle of the windscreen
fig. 75.
In the event of an imminent collision the
system intervenes by automatically
braking the car to prevent the impact or
reduce its effects.The system may brake slightly to warn
the driver when a potential frontal
accident is detected. Signals and limited
braking are intended to allow the driver
to react promptly, in order to prevent or
reduce the effects of a potential
accident.
Versions equipped with Stop/Start system:
at the end of the automatic braking, the
Stop/Start system will activate as
described in paragraph "Stop/Start
system" of this chapter.
Versions equipped with manual
transmission: at the end of the automatic
braking, the engine may stall and turn
off, unless the clutch pedal is pressed.
Versions equipped with automatic
transmission: at the end of the braking,
the last stored gear is engaged. The
vehicle may restart a few seconds after
the automatic stop.IMPORTANT After the car is stopped,
the brake callipers may be locked for
about 2 seconds for safety reasons.
Make sure you press the brake pedal if
the vehicle moves slightly forwards.
Engagement/disengagement
The Forward Collision Warning Plus
system can be deactivated (and then
reactivated) via theUconnect™system.
The system can also be deactivated by
74J0A0334C

SAFETY
sealants may damage the Tyre Pressure
Monitoring System sensor. If
aftermarket tyre sealant has been
used, it is recommended to go to a
Jeep Dealership to have the sensors
checked. After checking or adjusting
the tyre pressure, always refit the valve
cap to prevent humidity and dirt from
entering. They could damage the Tyre
Pressure Monitoring System sensor.
NOTE Some external factors (e.g.
external temperature, etc...) could affect
the information reported on the
instrument panel by the TPMS.
The tyre inflation pressure and the “low
pressure” reporting threshold could
change depending on the environmental
conditions.
TPMS check message
If a system failure is present, the
warning light flashes for about
75 seconds and then stays on solid. An
acoustic signal is also emitted.
TPMS deactivation
The TPMS can be deactivated by
replacing the wheels equipped with
TPMS with others that are not (e.g. when
replacing the wheel assemblies in
winter), if the country of purchase allows
it. Then drive the vehicle for at least
20 minutes at a speed higher than about25 km/h. The TPMS will emit an
acoustic warning, the
warning light
will flash for about 75 seconds, then will
stay on constantly and the instrument
panel will display the "Tyre pressure not
available" message with some dashes (–
–) instead of the pressure values.
The next time the engine is started, the
system will not emit any acoustic signal
and the display will not show the
message "Tyre pressure not available",
but the dashes (– –) will be still
displayed instead of the pressure value.
Operating example
Supposing that the prescribed cold
inflation pressure (i.e. vehicle stationary
for at least 3 hours) is 2.3 bar, if the
ambient temperature is 20°C and the
detected tyre pressure is 1.95 bar, a
temperature reduction of −7°C results in
a decrease in tyre pressure, bringing it to
approximately 1.65 bar. This pressure is
sufficiently low to activate the
warning
light.
Heating of tyres due to driving the
vehicle may increase tyre pressure up to
approximately 1.95 bar, but the
warning light will stay on. In this
situation, the warning light will switch off
only after the tyres are inflated to the
prescribed cold pressure value for the
car.
WARNING
68)The system is an aid for vehicle
driving, it DOES NOT warn the driver
about incoming vehicles outside of the
detection areas. The driver must always
maintain a sufficient level of attention to
the traffic and road conditions and for
controlling the trajectory of the vehicle.
69)The system is an aid for the driver,
who must always pay full attention while
driving. The responsibility always rests
with the driver, who must take into
account the traffic conditions in order to
drive in complete safety. The driver must
always maintain a safe distance from the
vehicle in front.
70)If the driver depresses the brake pedal
fully or carries out a fast steering during
system operation, the automatic braking
function may stop (e.g. to allow a possible
manoeuvre to avoid the obstacle).
71)The system intervenes on vehicles
travelling in the same lane. People,
animals and things (e.g. pushchairs) are
not taken into consideration.
113
STARTING THE ENGINE
116) 117) 118)44) 45) 46) 47)
Before starting the engine, adjust the
seat, the interior rear view mirrors, the
door mirrors and fasten the seat belt
correctly.
Never press the accelerator pedal for
starting the engine.
If necessary, messages indicating the
starting procedure can be shown on the
display.
LPG versions
The engine always starts up on petrol
independently of the previously selected
mode.
There must therefore always be some
petrol in the tank to protect the petrol
pump and to guarantee temporary
switching from Methane or LPG to petrol
operation, if high performance is
required.
PROCEDURE FOR VERSIONS
WITH MANUAL GEARBOX
Proceed as follows:engage the electric parking brake and
place the gear lever in neutral;
bring the ignition device to MAR. On
Diesel versions, waning lightlights upin the instrument panel: wait for the
warning light to switch off;
fully depress the clutch pedal without
touching the accelerator;
turn the ignition device to AVV and
release it as soon as the engine starts;
if the engine does not start within
10 seconds, bring the ignition device
back to STOP and wait for
10-15 seconds before repeating the
starting procedure.
PROCEDURE FOR VERSIONS
WITH AUTOMATIC
TRANSMISSION
Proceed as follows:engage the electric parking brake and
place the gear lever to P (Park) or N
(Neutral);
fully depress the brake pedal without
touching the accelerator;
place the ignition device to AVV;if the engine does not start, bring the
ignition device back to STOP and wait for
10-15 seconds before repeating the
starting procedure.
IMPORTANT If, with the ignition
device at MAR, thesymbol on the
instrument panel stays on together
with warning light
, turn the
ignition device to STOP and then back
to MAR. If the warning light (or thesymbol on the display) remains on, try
with the other keys provided with the
vehicle. Contact a Jeep Dealership if
the engine still does not start.
ENGINE STARTING FAILURE
Starting the engine with electronic key
battery (Keyless Enter-N-Go) run down or
flat
If the ignition device does not respond
when the relevant button is pressed the
electronic key battery might be run down
or flat. Therefore, the system does not
detect the presence of the electronic key
on board the vehicle and displays a
dedicated message.
In this case, rest the rounded edge of the
electronic key (the side opposite the
metal insert) on the ignition device and
press the button by the electronic key.
The ignition device is thus activated and
the engine can be started.
STOPPING THE ENGINE
Proceed as follows:park the car in a position that is not
dangerous for oncoming traffic; engage a
gear (versions with manual gearbox) or
position the gear lever to P (Parking)
(versions with automatic transmission);
turn the ignition device to STOP with
the engine idling.
