• When you turn ParkSense OFF, the instru-
ment cluster display will read
“PARKSENSE OFF.” Furthermore, once
you turn ParkSense OFF, it remains off until
you turn it on again, even if you cycle the
ignition.
• ParkSense, when on, will reduce the vol-
ume of the radio when it is sounding a tone.
• Clean the ParkSense sensors regularly, tak-
ing care not to scratch or damage them.
The sensors must not be covered with ice,
snow, slush, mud, dirt or debris. Failure to
do so can result in the system not working
properly. The ParkSense system might not
detect an obstacle behind the fascia/
bumper, or it could provide a false indica-
tion that an obstacle is behind the fascia/
bumper.
• Use the ParkSense switch to turn the
ParkSense system OFF if objects such as
bicycle carriers, trailer hitches, etc. are
placed within 12 inches (30 cm) from the
rear fascia/bumper. Failure to do so can
result in the system misinterpreting a close
object as a sensor problem, causing the“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message to be displayed in
the instrument cluster display.
• The operation of the rear sensors is auto-
matically deactivated when the trailer's
electric plug is inserted in the vehicle's tow
hook socket. The rear sensors are automati-
cally reactivated when the trailer's cable
plug is removed.
WARNING!
• Drivers must be careful when backing up
even when using ParkSense. Always
check carefully behind your vehicle,
look behind you, and be sure to check
for pedestrians, animals, other vehicles,
obstructions, and blind spots before
backing up. You are responsible for
safety and must continue to pay atten-
tion to your surroundings. Failure to do
so can result in serious injury or death.
• Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly is disconnected
from the vehicle when the vehicle is not
used for towing. Failure to do so can
WARNING!
result in injury or damage to vehicles or
obstacles because the hitch ball will be
much closer to the obstacle than the
rear fascia when the loudspeaker sounds
the continuous tone. Also, the sensors
could detect the ball mount and hitch
ball assembly, depending on its size and
shape, giving a false indication that an
obstacle is behind the vehicle.
CAUTION!
• ParkSense is only a parking aid and it is
unable to recognize every obstacle, in-
cluding small obstacles. Parking curbs
might be temporarily detected or not
detected at all. Obstacles located above
or below the sensors will not be detected
when they are in close proximity.
• The vehicle must be driven slowly when
using ParkSense in order to be able to
stop in time when an obstacle is de-
tected. It is recommended that the
driver looks over his/her shoulder when
using ParkSense.STARTING AND OPERATING

CAUTION!
• To avoid vehicle damage, ParkView
should only be used as a parking aid.
The ParkView camera is unable to view
every obstacle or object in your drive
path.
• To avoid vehicle damage, the vehicle
must be driven slowly when using
ParkView to be able to stop in time when
an obstacle is seen. It is recommended
that the driver look frequently over his/
her shoulder when using ParkView.
NOTE:
If snow, ice, mud, or any foreign substance
builds up on the camera lens, clean the lens,
rinse with water, and dry with a soft cloth. Do
not cover the lens.
REFUELING THE VEHICLE
Fuel Filler Cap
The fuel filler cap is located on the driver's
side of the vehicle. If the fuel filler cap is lost
or damaged, be sure the replacement cap is
the correct one for this vehicle.
WARNING!
• Never have any smoking materials lit in
or near the vehicle when the fuel door is
open or the tank is being filled.
• Never add fuel when the engine is run-
ning. This is in violation of most coun-
tries regulations and may cause the
“Malfunction Indicator Light” to turn
on.

“Fluids and lubricants” in the “Technical
specifications” section. The vehicle is
equipped with an automatic AdBlue heating
system when the engine starts allowing the
system to work correctly at temperatures
lower than 12 °F (-11 °C).
NOTE:
AdBlue freezes at temperatures lower than
12 °F (-11 °C).
AdBlue (UREA) Storage
AdBlue (UREA) is considered a very stable
product with a long shelf life. If AdBlue
(UREA) is kept in temperatures between
10° and 90°F (-12° and 32°C), it will last a
minimum of one year.
AdBlue (UREA) is subject to freezing at the
lowest temperatures. For example, AdBlue
(UREA) may freeze at temperatures at or
below 12° F (-11° C). The system has been
designed to operate in this environment.NOTE:
When working with AdBlue (UREA), it is
important to know that:
• Any containers or parts that come into con-
tact with AdBlue (UREA) must be AdBlue
(UREA) compatible (plastic or stainless
steel). Copper, brass, aluminum, iron or
non-stainless steel should be avoided as
they are subject to corrosion by AdBlue
(UREA).
• If AdBlue (UREA) is spilled, it should be
wiped up completely.
Adding AdBlue (UREA)
Preliminary Conditions
AdBlue (UREA) freezes at temperatures
lower than 12° F (-11° C). If the car stands for
a long time at this temperature refilling could
be difficult. For this reason, it is advised to
park the vehicle in a garage and/or heated
environment and wait for the urea to return to
liquid state before topping up.
Proceed as follows:
• Park the car on flat ground and stop the
engine by cycling the ignition to the OFF
position.• Open the fuel door, undo and remove the
cap (blue) from the AdBlue (UREA) filler.
Refilling With Nozzles
You can fill up at any AdBlue (UREA) dis-
tributor.
Proceed as follows:
• Insert the AdBlue (UREA) nozzle in the
filler, start refilling and stop refilling at the
first shut-off (the shut-off indicates that the
AdBlue (UREA) tank is full). Do not pro-
ceed with the refilling, to prevent spillage
of AdBlue (UREA).
• Extract the nozzle.
Refilling With Containers
Proceed as follows:
• Check the expiration date.
• Read the advice for use on the label before
pouring the content of the bottle into the
AdBlue (UREA) tank.
• If systems which cannot be screwed in (e.g.
tanks) are used for refilling, after the indi-
cation appears on the instrument panel
display refer to “Warning lights And Mes-
sages" in the “Getting To Know Your Instru-
169

ment Panel” for further information, fill the
AdBlue (UREA) tank with no more than
2 Gallons (8 liters).
• If containers which can be screwed to the
filler are used, the reservoir is full when the
AdBlue (UREA) level in the container stops
pouring out. Do not proceed further.
Operations After Refilling
Proceed as follows:
• Fit the cap back on the AdBlue (UREA)
filler by turning it clockwise and screwing it
completely.
• Cycle the ignition to RUN (it is not neces-
sary to start the engine).
• Wait for the indication on the instrument
panel to switch off before moving the car.
The indication may stay on for a few sec-
onds to approximately half a minute. If the
engine is started and the car is moved, the
indication will remain on for longer. This
will not compromise engine operation.• If the AdBlue (UREA) was topped up when
the tank was empty, wait for 2 minutes
before starting the engine.
NOTE:
• If AdBlue (UREA) is spilled out of the filler
neck, clean up well the area and proceed to
filling up again. If the liquid crystallizes,
eliminate it with a sponge and warm water.
• DO NOT EXCEED THE MAXIMUM LEVEL:
this could cause damage to the reservoir.
AdBlue (UREA) freezes at under 12° F
(-11° C). Although the system is designed
to operate below the freezing point of the
UREA, it is advisable not to fill the tank
beyond the maximum level because if the
UREA freezes the system can be damaged.
Follow the instructions in this section.
• If the AdBlue (UREA) is spilled on painted
surfaces or aluminium, immediately clean
the area with water and use absorbent ma-
terial to collect the fluid that has been
spilled on the ground.• Do not try to start the engine if AdBlue
(UREA) was accidentally added to the die-
sel fuel tank, this can result in serious
engine damage, contact an authorized
dealer.
• Do not add additives or other fluids to
AdBlue (UREA), doing so could damage the
system.
• The use of non-conforming or degraded
AdBlue (UREA) may lead to indications
appearing on the instrument panel display
refer to “Warning Lights And Messages" in
the “Getting To Know Your Instrument
Panel” for further information.
• Never pour AdBlue (UREA) into another
container: it could be contaminated.
• If the AdBlue (UREA) runs out, see refer to
“Warning Lights And Messages" in the
“Getting To Know Your Instrument Panel”
for further information to continue using
the car normally.
