with mud, ice or snow. When re-
verse gear is engaged, an audible
signal (long beep) indicates that the

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

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
