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 .
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 .
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
