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
s t y l e s a n d t o t h e p r o fi l e o f t h e r o a d ,
providing the best compromise be-
tween occupant comfort and vehicle
road holding.
The system alternates between soft
a n d fi r m s u s p e n s i o n s e t t i n g s , m a x i -
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.
