Jeep Renegade Owner's Handbook Manual page 115

The sensors are automatically
reactivated when the trailer's cable plug
is removed. Before using the Park-
Sense® system, it is recommended to
remove the tow hook ball assembly and
the relevant attachment from the vehi-
cle when the latter is not used for tow-
ing operations. Failure to comply with
this prescription may cause personal
injuries or damages 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.
In addition, the sensors may detect the
tow hook ball assembly and the
relevant attachment (depending on its
size and shape), providing a false
indication of the presence of an
obstacle in the area behind the vehicle.
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.
❒ the presence of adhesives on the
sensors. Thus take care not to place
adhesives on the sensors.
WARNING
126) 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 drive into. 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.
WARNING
42) The sensors must be clean of mud,
dirt, snow or ice in order for the system to
operate correctly. Be careful not to scratch
or damage the sensors while cleaning
them. Avoid using dry, rough or hard
cloths. The sensors should be washed
using clean water with the addition of car
shampoo if necessary. When using special
washing equipment such as high pressure
jets or steam cleaning, clean the sensors
very quickly keeping the jet more than
10 cm away.
43) Only have interventions on the bumper
in the area of the sensors carried out by
a Jeep Dealership. Interventions on the
bumper that are not carried out properly
may compromise the operation of the
parking sensors.
