be measured.

 During the measuring, go for-

prox. 20 km/h), to prepare for
your manoeuvre.
The system then measures the size of the space.

- when you switch off the ignition,
- if measuring is not requested,
- within fi ve minutes of selection of
the function,
- if the vehicle speed exceeds the threshold of 45 mph (approx.

If the lateral distance between your
vehicle and the parking space is too
large, the system may not be able to
measure the space.

one space during your search.
- In bad weather conditions or in winter, make sure that the sen-
sors are not covered by dirt, or
by ice or snow.

tary crossing of longitudinal traffi c
lane markings on the ground (con-
tinuous or discontinuous line).
Sensors, fi tted below the front
bumper, trigger a warning if the vehi-

crossed on the right,
- on the left-hand side, if the mark- ing on the ground has been
crossed on the left.
No warning is transmitted while the
direction indicator is active and for
approximately 20 seconds after the
direction indicator is switched off.
A warning may be transmitted if a di-
rection marking (arrow) or non-stand-
ard marking (graffi ti) is crossed. Operating fault In the event of a malfunction, the service

VISUAL AND AUDIBLE FRONT AND/OR REAR PARKING ASSISTANCE
System consisting of four proximity
sensors, installed in the front and/or
rear bumper.
It detects any obstacle (person, ve-
hicle, tree, barrier ...) located behind
the vehicle, however, it will not be
able to detect obstacles located im-
mediately below the bumper.
An object, such as a stake, a road-
works cone or any other similar ob-
ject may be detected at the start of
the manoeuvre but may no longer
be detected when the vehicle moves
nearer to it. The parking assistance is
switched
off :
- when you exit reverse gear,
- when the speed is higher than 6 mph (10 km/h) in forward
gear,
- when the vehicle has been sta- tionary for more than three sec-
onds in forward gear.
The parking assistance system
cannot, in any circumstances, re-
place the need for vigilance and
responsibility on the part of the
driver.
The parking assistance is
switched
on :
- by engaging reverse gear,
- at a speed below 6 mph (10 km/h) in forward gear.
This is accompanied by an audible
signal and/or displaying of the vehi-
cle on the multifunction display.
The proximity information is indicated
by:
- an audible signal which be- comes more rapid as the vehicle
approaches the obstacle,
- a diagram on the multifunction display, with blocks which move
closer to the vehicle.
The obstacle is located in relation to
the emission of the audible signal by
the speakers; front or rear and right
or left.
When the distance between the ve-
hicle and the obstacle is less than
approximately twenty-fi ve centime-
tres, the audible signal becomes
continuous and/or the "Danger"
symbol appears, depending on the
multifunction display version.

The rear pneumatic suspension en-
hances driving comfort by maintain-
ing a constant body height whatever
the vehicle load. Operation

cle load, a sinking of the rear of
the vehicle is detected and the
pneumatic springs infl ate in or-
der to compensate for the extra
weight.
- If there is a decrease in load, a rising of the rear of the vehicle is
detected and so the pneumatic
springs defl ate to return the ve-
hicle to its nominal height.
- If the vehicle has been unused for a long period, the pneumatic
springs may infl ate if necessary
when you unlock or open a door,
so as to return the vehicle to its
nominal height.
