2018 JEEP RENEGADE brake sensor

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%.

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

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.

IMPORTANT It is dangerous to leave
the device activated when it is not
used. There is a risk of inadvertently
activating it and losing control of the
vehicle due to unexpected excessive
speed.
Deactivation
With the device active, to deactivate it
press and release the
button. The
display will show a dedicated message.
SETTING THE DESIRED SPEED
The device can be set only with speeds
above 30 km/h (or 20 mph for markets
with instrument panels giving mph) and
under 160 km/h (or 100 mph for
markets with instrument panels
giving mph).
When the vehicle reaches the desired
speed, press and release the button SET
+ or SET to set the speed to the current
speed. The display will show the set
speed. Then take your foot off the
accelerator pedal.
The system cannot be set
when pressing the brake pedal;when the brakes are overheated;when the electric parking brake is
engaged;
when the shift lever is in the P (park),
R (reverse) or N (neutral) positions
(versions with automatic transmission orautomatic transmission with double
clutch);
when the shift lever is in the R
(reverse), neutral or in 1st (first gear
engaged) positions (versions with manual
transmission);
when the clutch is pressed (versions
with manual transmission);
when the engine speed exceeds a
maximum threshold (versions with
manual transmission and versions with
automatic transmission/automatic
transmission with double clutch) or goes
below a minimum threshold (only
versions with manual transmission);
when the car speed is not within the
settable speed range;
when the ESC (or ABS or other
stability control systems) are operating or
have just operated;
when the ESC system is off;during automatic braking by the
Forward Collision Warning Plus system
(where provided);
when the Speed Limiter is active;when the electronic Cruise Control is
active;
in case of failure of the device;when the engine is off;in case of obstruction of the radar
sensor (in this case the bumper area
where it is located must be cleaned).
IMPORTANT The device does not
deactivate on reaching speeds higher
than those that can be set (160 km/h
or 100 mph for instrument panel set
to mph) with the accelerator pedal
pressed. In these conditions, the
device may not work correctly and it is
advisable to deactivate it.
CHANGING SPEED
Speed increase
After having set the device, the stored
speed can be stored by holding the SET
+ button pressed.
Press the SET + button once: the set
speed will increase by 1 km/h (or by
1 mph when the measurement unit is set
to mph). Each touch of the button once
will increase the speed by 1 km/h (or by
1 mph, the latter for instrument panels
set to miles per hour).
Hold the SET + button pressed: the set
speed will increase in 10 km/h steps (or
in 5 mph steps when the measurement
unit is set to mph) until the button is
released. The set speed increase is
shown on the display.
Decreasing speed
After having set the device, the stored
speed can be reduced by holding the
SET – button pressed.
164
STARTING AND DRIVING

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;
166
STARTING AND DRIVING

the device keeps working if the radar
sensor is obstructed.
Before returning to the previously set
speed, bring the speed close to that
value, then press the RES button and
release it.
WARNING
134)Pay the utmost attention while
driving at all times and be always ready to
press the brakes if needed.
135)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.
136)The device is not activated in
presence of pedestrians, oncoming
vehicles in the opposite direction of travel
or moving in the crosswise direction and
stationary objects (e.g. a vehicle standing
in a queue or a broken down vehicle).
137)The device cannot take account of
road, traffic and weather conditions, and
conditions of poor visibility (e.g. fog).138)The device does not always fully
recognise complex driving conditions that
could cause it to determine the safe
distance to be held incorrectly or not at
all.
139)The device cannot apply the
maximum braking force: the car will not
be stopped completely.IMPORTANT
54)The system may have limited or absent
operation due to weather conditions such
as: heavy rain, hail, thick fog, heavy snow.
55)The section of the bumper before the
sensor must not be covered with
adhesives, auxiliary headlights or any other
object.
56)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.
57)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.58)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.
59)Do not wash with high-pressure jets in
the bumper lower area: in particular do not
operate on the system's electrical
connector.
60)Be careful in the case of repairs and
new paintings in the area around the
sensor (panel covering the sensor on the
left side of the bumper). In the event of a
frontal impact the sensor may
automatically deactivate and display a
warning to indicate that the sensor needs
to be repaired. Even without a malfunction
warning, deactivate the system operation if
you think that the position of the radar
sensor has changed (e.g. due to low-speed
frontal impact as during parking
manoeuvres). In these cases, go to a Jeep
Dealership to have the radar sensor
realigned or replaced.
167

GENERAL WARNINGS
Some conditions may influence the
performance of the parking system:
reduced sensor sensitivity and a
reduction in the parking assistance
system performance could be due to the
presence of: ice, snow, mud, thick paint,
on the surface of the sensor;
the sensor may detect a non-existent
obstacle ("echo interference") due to
mechanical interference, for example
when washing the vehicle, in rain (strong
wind), hail;
the signals sent by the sensor can
also be altered by the presence of
ultrasonic systems (e.g. pneumatic brake
systems of trucks or pneumatic drills)
near the vehicle;
Parking assistance system
performance can also be influenced by
the position of the sensors, for example
due to a change in the ride setting
(caused by wear to the shock absorbers,
suspension), or by changing tyres,
overloading the vehicle or carrying out
specific tuning operations that require
the vehicle to be lowered.
the presence of a tow hook without
trailer, which may interfere with the
correct operation of the parking sensors.
Before using theParkSense®system, it
is recommended to remove the
removable tow hook ball assembly andthe relevant attachment from the vehicle
when the latter is not used for towing
operations. Failure to comply with this
prescription may cause personal injuries
or damage to vehicles or obstacles since,
when the continuous acoustic signal is
emitted, the tow hook ball is already in a
position that is much closer to the
obstacle than the rear bumper. If you
wish to leave the tow hook fitted without
towing a trailer, it is advisable to contact
a Jeep Dealership for the relevant system
update operations because the tow hook
could be detected as an obstacle
ParkSense®by the central sensors.
the presence of adhesives on the
sensors. Thus take care not to place
adhesives on the sensors.
WARNING
140)Parking and other potentially
dangerous manoeuvres are, however,
always the driver’s responsibility. When
performing these operations, always make
sure that there are no other people
(especially children) or animals on the
route you want to take. The parking
sensors are an aid for the driver, but the
driver must never allow their attention to
lapse during potentially dangerous
manoeuvres, even those executed at low
speeds.
170
STARTING AND DRIVING

PARALLEL AND
PERPENDICULAR PARKING
DESCRIPTION
Activation
The system is activated pressing the
button on the dashboard (see "On/off"
paragraph): after being selected, the
system activates in search mode.
Considering that the system recognises
parking places even when it has not been
selected, it can be activated even
immediately after passing close to a
parking place suitable for the type of car.
The system will inform the driver,
through the instrument panel display,
about the operations to be performed for
a correct manoeuvre.
Selecting the type of parking
During the search and until the reverse
gear is engaged, the preferred type can
be selected for parking:
"Parallel": the car will search a parking
place parallel to the driving direction;
"Perpendicular": the vehicle will
search a parking place perpendicular to
the driving direction.
Selection of the search side
To select the search side and perform the
correct manoeuvre, act as follows:
Select the search for the parking
place and the manoeuvre on thepassenger side placing the direction
indicator in centre position (deactivated)
or pushed upwards.
Select the search for the parking
area and manoeuvre on the driver side
pushing the direction indicator
downwards.
Search for a parking place
Through the side sensors, the system
continuously searches for a free parking
place, suitable for the car’s dimensions.
While searching the vehicle should
continue following its route at a speed of
below 30 km/h and at a distance of
around 50 cm to 1.5 m from parked
vehicles.
A parking place is considered suitable if
it is about 80 cm longer than the
dimensions of the vehicle for parking
placesparallelto the driving direction
and about 1 m per parking places
perpendicularto the driving direction,
compared to the vehicle's dimensions.
IMPORTANT While searching, vehicle
speed should not exceed 30 km/h;
when 25 km/h have been reached, the
driver is asked to decrease the speed;
if the speed of 30 km/h is exceeded, it
is deactivated (in this case, the system
can be restarted by pressing the button
on the instrument panel).
Manoeuvre
During manoeuvre, the vehicle's
movements can be controlled by
operating the accelerator, brake and
clutch pedals (versions with manual
gearbox), or the accelerator and brake
pedals (versions with automatic
transmission). Once a parking place has
been found, you will be asked to engage
reverse, leave the steering wheel and use
the pedals, while the system handles the
steering automatically to perform the
parking operation in the dedicated area.
During the manoeuvre it will be possible
to take advantage of the information
coming from the parking sensors (when
driving in reverse it is advisable to reach
the area where the rear sensors sound
continuously), but it is always advisable
to keep an eye on the surrounding area.
The car can be stopped during the
manoeuvre and, whilst remaining
stationary, reverse gear can temporarily
be released (for example, to allow a
pedestrian to go by in the area of the
manoeuvre).
The parking manoeuvre will be
interrupted in the following cases:
vehicle's speed is above 7 km/h;the steering is (voluntarily or
unintentionally) moved (by grabbing it or
preventing it from moving);
