speed
The accelerator pedal has an end-
of-travel switch. In order to exceed
the memorised maximum speed at
any time, you can press the pedal
all the way down. While the speed

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.
Press button A again, the warn-
ing light 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.
It allows you to alternate between
s o f t a n d fi r m s u s p e n s i o n s e t t i n g s ,
maximising comfort at the same
time as permanently guaranteeing
the highest level of safety. It also
automatically corrects road holding,
according to the vehicle load and
driving conditions.
Also, the "Hydractive III+" suspen-
sion gives you the possibility of
choosing 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 on button A . Display on the instrument
panel
The suspension mode selected is
displayed on the instrument panel
display.
Normal mode
This mode favours soft damp-
ing for maximum comfort.
If the speed authorised for a
particular position is exceed-
ed, the vehicle reverts auto-
matically 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 display.
SPORT mode is retained when you
switch off the engine.
