ACTIVE SAFETY SYSTEMS
ABS (Anti-lock Braking System)
This system, which is an integral part of
the braking system, prevents one or more
wheels from locking and slipping in all
road surface conditions, irrespective of
the intensity of the braking action,
ensuring that the vehicle can be
controlled even during emergency
braking and optimising stopping
distances.
System intervention
The driver can feel that the ABS system
has come into action because the brake
pedal pulsates slightly and the system
gets noisier: this is entirely normal with
the system operating.
36) 37) 38) 39) 40) 41) 42)
DTC (Drag Torque Control)
SYSTEM
The DTC (Drag Torque Control) System
prevents the locking of the drive wheels
that may occur in the event, for example,
of sudden release of the accelerator
pedal or abrupt downshifting in low-grip
conditions.
In such conditions, the braking effect of
the engine may cause slipping of the
drive wheels and consequent loss of
vehicle stability. In these situations, theDTC system intervenes by restoring
torque to the engine in order to preserve
stability and increase vehicle safety.
ESC (Electronic Stability Control)
SYSTEM
The ESC system improves the directional
control and stability of the vehicle in
various driving conditions, correcting
understeer and oversteer, distributing the
brake force on the appropriate wheels.
System intervention
The intervention of the system is
indicated by the flashing of the
warning light on the instrument panel,
to inform the driver that the vehicle is in
critical stability and grip conditions.
43) 44) 45) 46) 47)
TC (Traction Control) SYSTEM
The system automatically operates in the
event of slipping, loss of grip on wet
roads (aquaplaning) and acceleration on
slippery, snowy or icy roads, etc. on one
or both drive wheels.
System intervention
The intervention of the system is
indicated by the flashing of the
warning light on the instrument panel,
to inform the driver that the vehicle is in
critical stability and grip conditions.
48) 49) 50) 51) 52)
PBA (Panic Brake Assist) SYSTEM
The PBA system is designed to improve
the vehicle’s braking capacity during
emergency braking.
The brake pedal should be pressed
continuously during braking, avoiding
intermittent presses, to get the most out
of the system. Do not reduce pressure on
the brake pedal until braking is not
necessary anymore.
The PBA system is deactivated when the
brake pedal is released.
53) 54) 55)
HSA (Hill Start Assist)
It is an integral part of the ESC system
and facilitates starting on an incline.
56) 57)
DST SYSTEM (Dynamic Steering
Torque)
The DST function uses the integration of
the ESC system with the electric power
steering to increase the safety level of
the whole vehicle.
58)
102
SAFETY
ERM (Electronic Rollover
Mitigation) SYSTEM
The system monitors the tendency of the
wheels to rise from the ground if the
driver performs extreme manoeuvres like
quick steering to avoid an obstacle,
especially in poor road conditions.
If these conditions occur, the system
intervenes on the brakes and engine
power to reduce the possibility that the
wheels are raised from the ground. It is
not possible to avoid tendency to roll over
if the phenomenon is due to reasons
such as driving on high side gradients,
collision with objects or other vehicles.
59)
TSC (Trailer Sway Control)
SYSTEM
The system employs a series of sensors
located on the vehicle to identify
excessive swerving of the trailer and take
the necessary precautions to eliminate it.
System intervention
When the system is active, the
warning light flashes on the
instrument panel, the engine power is
reduced and braking can be felt on the
individual wheels, following the attempt
to eliminate the swerving of the trailer.
The system is active only with ESC
engaged.When the ESC system is deactivated (by
pressing the button on the central
tunnel), the TSC system is deactivated as
well.
60) 61)
HDC (Hill Descent Control)
SYSTEM
(where provided)
62) 63)
On cars equipped in this way, this
function is an integral part of the ESC
system and is aimed at keeping the car
at a constant speed during a descent,
operating autonomously and in different
ways on the brakes.
In this way the vehicle stability and
completely safe driving are guaranteed,
above all in poor grip conditions and
steep descents.
Enabling the system
To enable the system, press the button
fig. 70.The system is enabled if the following
conditions are met:
theSelec-Terrain™device is in 4WD
LOW mode;
the vehicle speed is below 12 km/h;the electric parking brake (EPB) is
deactivated;
the driver side door is closed.
The system activation is reported by the
continuous switching-on of the icon
on
the display along with a dedicated
message.
Activation of the system
Once enabled, the HDC system will
activate automatically if the vehicle is
driven downhill on a steep slope, higher
than 8%.

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
72)If the car must be placed on a roller
bench for maintenance interventions or if
it is washed in an automatic roller washing
tunnel with an obstacle in the front part
(e.g. another car, a wall or another
obstacle), the system may detect its
presence and activate. In this case the
system must be deactivated through the
settings of theUconnect™system.
73)The presence of the TPMS does not
permit the driver to neglect regular checks
of the tyre pressure, including for the
spare wheel, and correct maintenance: the
system is not used to signal a possible
fault to a tyre.
74)Tyre pressure must be checked with
tyres rested and cold. Should it become
necessary for whatever reason to check
pressure with warm tyres, do not reduce
pressure even though it is higher than the
prescribed value. Repeat the check when
the tyres are cold.
75)Should one or more wheels be fitted
without sensors (e.g. if the spare wheel is
fitted), the system will no longer be
available for the replaced wheel and a
warning message will be shown on the
display, until the wheels with sensors are
fitted again.76)The TPMS cannot indicate sudden
tyre pressure drops (e.g. if a tyre bursts).
In this case, stop the vehicle, braking with
caution and avoiding abrupt steering.
77)Replacing standard tyres with winter
tyres and vice versa requires TPMS system
adjustment that must only be performed
by Jeep Dealerships.
78)Changes in outside temperature may
cause tyre pressures to vary. The system
may temporarily indicate insufficient
pressure. In this case, check the tyre
pressure when cold and, if necessary,
restore the inflation values.
79)When a tyre is removed, it is advisable
to replace the rubber valve seal as well:
contact a Jeep Dealership. The
fitting/removal of the tyres and/or rims
require special care. To avoid damaging or
fitting the sensors incorrectly, tyre and/or
rim fitting/removal operations should only
be carried out by specialised staff.
Contact a Jeep Dealership.
IMPORTANT
33)The system may have limited or absent
operation due to weather conditions such
as: heavy rain, hail, thick fog, heavy snow.34)The section of the bumper before the
sensor must not be covered with
adhesives, auxiliary headlights or any other
object.
35)System intervention might be
unexpected or delayed when other vehicles
transport loads projecting from the side,
above or from the rear, with respect to the
normal size of the vehicle.
36)Operation can be adversely affected by
any structural change made to the vehicle,
such as a modification to the front
geometry, tyre change, or a heavier load
than the standard load of the vehicle.
37)Incorrect repairs made on the front
part of the vehicle (e.g. bumper, chassis)
may alter the position of the radar sensor,
and adversely affect its operation. Go to a
Jeep Dealership for any operation of this
type.
38)Do not tamper with nor carry out any
intervention on the radar sensor or on the
camera on the windscreen. In the event of
a sensor failure, contact a Jeep
Dealership.
39)When towing a trailer (with modules
installed after purchasing the vehicle), a
vehicle or during loading manoeuvres on a
vehicle transporter (or in vehicle for
transport), the system must be deactivated
via theUconnect™system.

SAFETY
the pretensioner, wear the seat belt
tight to the torso and pelvis.
LOAD LIMITERS
To increase safety in the event of an
accident, the front seat belt retractors
contain a load limiter which controls the
force acting on the chest and shoulders
during the belt restraining action in the
event of a head-on collision.
GENERAL INSTRUCTIONS FOR
USING THE SEAT BELTS
Respect and ensure that all the other
occupants of the vehicle comply with the
local laws in force regarding the use of
seat belts. Always fasten the seat belts
before setting off.
Seat belts must also be worn by pregnant
women: the risk of injury in the event of
an accident is reduced for them and the
unborn child if they are wearing a seat
belt.
Pregnant women must position the lower
part of the belt very low down so that it
passes over the pelvis and under the
abdomen fig. 86. While pregnancy
increases, the driver must adjust both
seat and steering wheel to have full
control over the vehicle (pedals and
steering wheel should be easilyaccessed). The maximum clearance
should be kept between the abdomen
and the steering wheel.
The seat belt must not be twisted. The
upper part must pass over the shoulder
and cross the chest diagonally fig. 87.
The lower part must adhere to the pelvis,
not to the abdomen of the occupant.
Never use devices (clips, clamps, etc.)
that hold the seat belt away from your
body.Each seat belt must be used by only one
person. Never travel with a child sitting
on the passenger's lap and a single belt
to protect them both fig. 88. In general,
do not place any objects between the
person and the belt.

SAFETY
92)Incorrect fitting of the child restraint
system may result in an inefficient
protection system. In the event of an
accident the child restraint system may
become loose and the child may be
injured, even fatally. When fitting a
restraint system for newborns or children,
strictly comply with the instructions
provided by the Manufacturer.
93)When the child restraint system is not
used, secure it with the seat belt or with
the ISOFIX anchorages, or remove it from
the vehicle. Do not leave it unsecured
inside the passenger compartment. In this
way, in the case of sudden braking or an
accident, it will not cause injuries to the
occupants.
94)After installing a child restraint
system, do not move the seat: always
remove the child restraint system before
making any adjustment.
95)Always make sure that the chest
section of the seat belt does not pass
under the arms or behind the back of the
child. In the event of an accident the seat
belt will not be able to secure the child,
with the risk of injury, including fatal
injury. Therefore the child must always
wear the seat belt correctly.96)Do not use the same lower anchorage
to install more than one child restraint
system.
97)If a Universal ISOFIX child seat is not
fixed to all three anchorages, the child
seat will not be able to protect the child
correctly. In a crash, the child could be
seriously or fatally injured.
98)Fit the child restraint system when the
car is stationary. The child restraint
system is correctly fixed to the brackets
when you hear the click. Follow the
instructions for assembly, disassembly
and positioning that the Manufacturer
must supply with the child restraint
system.
99)If the vehicle was involved in an
accident of a certain severity, have the
ISOFIX anchorages and the child restraint
system replaced.
100)If the vehicle was involved in an
accident of a certain severity, have both
the child restraint system and the seat
belt it was attached to replaced.SUPPLEMENTARY
RESTRAINT SYSTEM (SRS)-
AIRBAG
The vehicle is equipped with:front driver airbag;front passenger airbag;driver and passenger front side bags
for pelvis, chest and shoulder protection
(Side bags);
front and rear side passenger side
bags for head protection (window bag).
FRONT AIRBAGS
The front driver/passenger airbags and
the driver knee bag (where provided)
protect the front seat occupants in the
event of frontal impacts of medium/high
severity, by placing the bag between the
occupant and the steering wheel or
dashboard.
Therefore non-activation of airbags in
other types of collisions (side impacts,
rear shunts, roll-overs, etc.) does not
indicate a system malfunction.
The driver and passenger front airbags
are not a replacement for, but are
complementary to, the seat belts, which
should always be worn as required by law
in Europe and most non-European
countries.
In the event of impact, anyone not
wearing a seat belt is projected forwards
137
and may come into contact with the bag
while it is still inflating. The protection
offered by the bag is compromised in
these circumstances.
The front airbags may not activate in the
case of a frontal impact against highly
deformable objects not involving the
front surface of the car (e.g. wing
collision against guard rail) or in the case
of the car wedging under other cars or
protective barriers (e.g. under trucks or
guard rails).
Failure to activate in the conditions
described above is due to the fact that
they may not provide any additional
protection compared with seat belts, so
their activation would be inappropriate.
In these cases, non-deployment does not
indicate a system malfunction.Driver's side front airbag

This consists of an instantly inflating bag
contained in a special compartment in
the centre of the steering wheel fig. 97.
IMPORTANT Do not use particularly
aggressive products to clean the
steering wheel airbag cover.
Passenger front airbag

This consists of an instantly inflating bag
contained in a special recess in the
dashboard fig. 98; this bag has a larger
volume than that of the driver's.

SAFETY
When the airbag deploys it emits a small
amount of dust: the dust is harmless and
does not indicate the beginning of a fire.
The dust may irritate the skin and eyes
however: in this case, wash with neutral
soap and water.
Airbag checking, repair and replacement
must be carried out at a Jeep Dealership.
If the car is scrapped, have the airbag
system deactivated at a Jeep Dealership.
Pretensioners and airbags are deployed
in different ways on the basis of the type
of collision. Failure to activate one or
more of the devices does not indicate a
system malfunction.
WARNING
101)Do not apply stickers or other objects
on the steering wheel, on the dashboard in
the passenger side airbag area, on side
upholstery on the roof or on the seats.
Never put objects (e.g. mobile phones) on
the passenger side of the dashboard since
they could interfere with correct inflation
of the passenger airbag and also cause
serious injury to the passengers.102)Always drive with your hands on the
rim of the steering wheel so that the
airbag can inflate freely if required. Do not
drive with your body bent forward. Keep
your back straight against the backrest.
103)When there is an active passenger
airbag, DO NOT install rearward facing
child restraint systems on the front seat.
Deployment of the airbag in an accident
could cause fatal injuries to the child
regardless of the severity of the impact.
Therefore, always deactivate the passenger
side airbag when a rearward facing child
restraint system is installed on the front
passenger seat. The front passenger seat
must also be positioned back as far as
possible in order to prevent the child
restraint system from coming into contact
with the dashboard. Immediately
reactivate the passenger airbag as soon as
the child restraint system has been
removed.
104)Do not affix rigid objects to the
garment hooks or support handles.
105)Do not rest your head, arms or
elbows on the door, windows or the area in
which the Window bag is located to avoid
possible injury during airbag inflation.
106)Never lean your head, arms or elbows
out of the window.107)If, when the ignition device is turned
to MAR, the
warning light does not
switch on or stays on whilst driving, a fault
may have occurred in the restraint
systems. In this case the airbags or
pretensioners may not be deployed in an
impact or, in a lower number of cases,
they may be deployed accidentally. Before
continuing, contact a Jeep Dealership
immediately to have the system checked.
108)In some versions, in the event of a
LED
OFFfailure (located on the
dashboard trim), thewarning light on
the instrument panel turns on and the
passenger side airbags are deactivated. In
some versions, in the event of a LED
ONfailure (located on the dashboard
trim), thelight on the console turns
on.
109)On cars with side bags, do not cover
the front seat backrests with extra covers.
110)Do not travel carrying objects in your
lap, in front of your chest or between your
lips (pipe, pencils, etc.): they could cause
severe injury if the airbag is deployed.
111)If the car has been stolen or in the
case of attempt to steal it, if it has been
subjected to vandalism or floods, have the
airbag system checked by a Jeep
Dealership.
