D R I V I N G The parking sensors system cannot,
in any circumstances, replace the
need for vigilance and responsibility
on the part of the driver.
VISUAL AND AUDIBLE FRONT AND/OR REAR PARKING SENSORS
System consisting of proximity sen-
sors, installed in the front and/or rear
bumper.
It detects any obstacle (person, vehi-
cle, tree, barrier...) located in front of
or behind the vehicle, however, it will
not be able to detect obstacles locat-
ed immediately 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 sensors are
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 screen.
The proximity information is indicat-
ed 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 thirty centimetres,
the audible signal becomes con-
tinuous and/or the "Danger" symbol
appears, depending on the multi-
function screen version.
The parking sensors are 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 station- ary for more than three seconds in
forward gear. Deactivation

 Press button A , the warning lamp
comes on, the system is fully de-
activated.
The system will be deactivated au-
tomatically when a trailer is being
towed or when a bicycle carrier is
fi tted (vehicle fi tted with a towbar
or bicycle carrier recommended by
CITROËN).

Reactivation
In bad weather or in winter, ensure
that the sensors are not covered
with mud, ice or snow. When re-
verse gear is engaged, an audible
signal (long beep) indicates that the
sensors may be dirty.
When the speed of the vehicle is
below about 6 mph (10 km/h), some
sources of noise (motorcycle, lorry,
pneumatic drill, ...) may trigger the
audible parking sensor signals.

 Press button A again, the warn-
ing lamp switches off, the system
is reactivated.
"HYDRACTIVE III +" ELECTRONIC SUSPENSION
The suspension automatically and
instantly adjusts to different driving
styles and to the profi le of the road,
providing the best compromise be-
tween occupant comfort and vehicle
road holding.
The system alternates between soft
and fi rm suspension settings, maxi-
mising comfort at the same time as
constantly ensuring the highest level
of safety. It also automatically cor-
rects ride height, according to the
vehicle load and driving conditions.
In addition, the "Hydractive III +" sys-
tem allows you to choose between
two modes of suspension.
A change of suspension mode can
be made either when the vehicle is
moving or when stationary, by press-
ing button A . Display on the instrument
panel
The suspension mode selected is
displayed on the instrument panel
screen.
Normal mode
This mode favours soft
damping for maximum com-
fort.
If the speed authorised for a
particular position is exceed-
ed, the vehicle reverts automatically
to the normal road position.
SPORT mode
This mode favours dynamic
driving.
The warning lamp on but-
ton A comes on in addition
to the message on the in-
strument panel screen.

SPORT mode is retained when you
switch off the engine.

Maximum height
Changing a wheel (not possible if
speed > 6mph (10km/h)).
Intermediate position
For increased ground clearance (not
possible if speed > 25 mph (40 km/h)).
For use on diffi cult roads when tra-
velling at reduced speed, as well as
on car park ramps.

Position changes may only be
made when the engine is running.
The adjustable ground clearance
meets all types of situation. Apart
from a few specifi c situations, the
vehicle should be in the Normal po-
sition.

 Press once on one of the adjust-
ment controls.
The change in position is indicated
by a message on the instrument

Position not authorised
The instrument panel screen tempo-
rarily displays a message indicating
that this position is not authorised.
The vehicle remains in the autho-
rised position and the instrument
panel screen indicates this position
to you.
Automatic variation of ground clea-
rance
- If your speed exceeds 70 mph (approx. 110 km/h), on a good
road surface, ground clearance
is lowered. The vehicle returns
to its normal position if the road
surface deteriorates or if your
speed is lower than 55 mph (ap-
prox. 90 km/h).
- At low or medium speed, if the road surface is poor, ground
clearance is increased. The ve-
hicle returns to its normal posi-
tion as soon as conditions allow.
- On switching off the ignition, the ground clearance is reduced to
the parking position
For your safety if you are operat-
ing underneath the vehicle, you
must support the vehicle with
axle stands.
