DRIVING
PARKING SENSORS
This system indicates the proximity
of an obstacle (person, vehicle, tree,
gate, etc.) which comes within the
fi eld of detection of sensors located
in the bumper.
Certain types of obstacle (stake,
roadworks cone, etc.) detected ini-
tially will no longer be detected at
the end of the manoeuvre due to the
presence of blind spots.


Visual assistance
This supplements the audible signal
by displaying bars in the multifunc-
tion screen which move progressively
nearer to the vehicle. When the ob-
stacle is near, the "Danger" symbol is
also displayed in the screen.

Audible assistance
The proximity information is given
by an intermittent audible signal, the
frequency of which increases as the
vehicle approaches the obstacle.
The sound emitted by the speaker
(right or left) indicates the side on
which the obstacle is located.
When the distance between the
vehicle and the obstacle becomes
less than approximately thirty centi-
metres, the audible signal becomes
continuous.


This function cannot, in any circum-
stances, take the place of the vigi-
lance and responsibility of the driver.



Rear parking sensors

The system is switched on by engag-
ing reverse gear. This is accompanied
by an audible signal.
The system is switched off when you
exit reverse gear.

DRIVING






Front parking sensors

In addition to the rear parking sensors,
the front parking sensors are triggered
when an obstacle is detected in front
and the speed of the vehicle is still be-
low 6 mph (10 km/h).
The front parking sensors are inter-
rupted if the vehicle stops for more
than three seconds in forward gear,
if no further obstacles are detected
or when the speed of the vehicle ex-
ceeds 6 mph (10 km/h).
The sound emitted by the speaker
(front or rear) indicates whether the
obstacle is in front or behind.



Deactivation/Activation of the
front and rear parking sensors
The function is deactivated by press-
ing this button. The indicator lamp in
the button comes on.
Pressing this button again reacti-
vates the function. The indicator
lamp in the button goes off.



The function will be deactivated au-
tomatically if a trailer is being towed
or a bicycle carrier is fi tted (vehicle
fi tted with a towbar or bicycle car-
rier recommended by CITROËN).



Operating fault

In the event of a malfunction
of the system, when reverse
gear is engaged this warn-
ing lamp is displayed in the
instrument panel and/or a message
appears in the screen, accompanied
by an audible signal (short beep).
Contact a CITROËN dealer or a
qualifi ed workshop.


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 vehicle is moving at a
speed below 6 mph (10 km/h), cer-
tain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trig-
ger the audible signals of the parking
sensor system.

PNEUMATIC SUSPENSION

Grand
C4 Picasso

C4 Picasso

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

Operation



- If there is an increase in vehicle
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.
If you do not reactivate the system
manually, automatic height correc-
tion will be activated as soon as the
vehicle starts to move. During height
correction, the service warning lamp
comes on and a message on the
screen reminds you not to exceed
6 mph (10 km/h).
The automatic correction does not
function if the doors or the boot are
open.
The automatic correction operates
even if your vehicle is in power
economy mode.
Activation/Deactivation
The automatic height correction can
be deactivated:


)
press button B
located on the
left hand boot interior trim for ap-
proximately two seconds,

)
release the button when you
hear a beep. Deactivation is con-
fi rmed by the lighting of the indi-
cator lamp in button B
.

In the event of a system fault,
alert messages, always in asso-
ciation with the service warning
lamp, will appear in the instru-
ment panel . Contact a CITROËN
dealer or a qualifi ed workshop.

You must deactivate the system in
the following circumstances:


- when working under the vehicle,

- when changing a wheel,

- when transporting the vehicle on
a lorry or ferry.
To reactivate automatic height cor-
rection:


)
press button B
again for approxi-
mately two seconds,

)
release the button when you hear
a beep. Activation is confi rmed
by the extinction of the indicator
lamp in button B
.
