PNEUMATIC SUSPENSION

Grand

C4 Picasso
The rear pneumatic suspension en-
hances driving comfort by maintain-
ing a constant body height whatever
the vehicle load. Operation
- If there is an increase in vehi-
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.
If you do not reactivate the system
manually, the automatic correction
will be activated as soon as the ve-
hicle starts to move. During the cor-
rection, the service warning lamp
lights up and a message on the
screen reminds you not to exceed
10 km/h (6 mph).
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 correction can be de-
activated:

 press on the button B for approx-
imately two seconds,

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

In the event of the system mal-
functioning, alert messages,
always in association with the
service warning lamp, will dis-
play in the instrument panel .
Consult a CITROËN dealer.
