The images from the camera(s)
displayed on the touch screen may be
distorted by the terrain.
In shady areas, or in inadequate sunlight
or lighting conditions, the image may be
darkened and with lower contrast.
The manoeuvre can be permanently interrupted
at any time, either by the driver or automatically
by the system.
Interruption by the driver can be done by:
– taking over control of the steering.
– activating the direction indicator lamps on the
opposite side to that of the manoeuvre.
– unfastening the seat belt.
– switching off the ignition.
The manoeuvre is automatically interrupted by
the system in the following cases:
– vehicle exceeding the speed limit of
5 mph (7 km/h) during parking space entry
manoeuvres, or 3 mph (5 km/h) during parking
space exit manoeuvres.
– activation of anti-slip regulation on a slippery
road.
– opening of a door or the boot.
– engine stall.
– system malfunction.
– after 10 manoeuvres to enter or exit a parallel
parking space and after 7 manoeuvres to enter a
parking bay.
Interrupting the manoeuvre automatically
deactivates the function.
Depending on audio equipment, the manoeuvre
symbol is displayed in red, accompanied by the
"Manoeuvre cancelled" message on the touch
screen.
A message prompts the driver to take back
control of the vehicle.
The function is deactivated after a few seconds
and returns to the initial display.
Depending on audio equipment, this
indicator lamp goes off.
End of the parking space entry or exit
manoeuvre
The vehicle stops as soon as the manoeuvre is
completed.
Depending on audio equipment, the manoeuvre
symbol is displayed in red, accompanied by the
message "Manoeuvre completed" on the touch
screen.
Depending on audio equipment, when the
function is deactivated, this indicator lamp
goes off, accompanied by an audible signal.
When entering a parking space, the driver may
be required to complete the manoeuvre.
Operating limits
– The system may suggest an inappropriate
parking space (parking prohibited, work in
progress with damaged road surface, location
alongside a ditch, etc.).
– The system may indicate that a space has
been found but will not offer it because of a fixed
obstacle on the opposite side of the manoeuvre,
which would not allow the vehicle to follow a
trajectory required for parking.
– The system may indicate that a space has
been found but the manoeuvre will not be
triggered, because the width of the lane is
insufficient.
– The system is not designed for performing the
parking manoeuvre on a sharp bend.
– The system does not detect spaces that
are much larger than the vehicle itself or that
are delimited by obstacles that are too low
(pavements, studs, etc.) or too thin (trees, posts,
wire fences, etc.).
– If the boot is heavily loaded, the tilt of the
vehicle towards the rear may interfere with the
distance measurements.
Do not use the function under the
following exterior conditions:
– Alongside a soft shoulder (e.g. ditch) or
quay or on the edge of a drop.
– When the road surface is slippery (e.g. ice).
If any of the following malfunctions
occurs, do not use the system:
– If a tyre is under-inflated.
– If one of the bumpers is damaged.
– If one of the cameras is faulty.
