Its status can be changed from unused to
operational only if:
the handbrake is engaged or the shift
lever is in the P position;
the engine is off;
the tailgate is open.
There is a LED on the button 1, which may
be in one of the following states:
LED off: indicates that at least one of
the above conditions is not met, or the
trailer light wiring is connected to the
socket.
LED flashing: indicates that the tow
hook is moving or that the system must
be initialised;
LED on fixed: indicates that the tow

hook can be moved.
Safe opening and closing of the tow hook
is guaranteed by a protection system
that can stop and reverse its movement
when it encounters an obstacle while
opening or closing.
The system must be initialised after the
battery has been disconnected, the
movement has been blocked by a
physical obstacle or if the safety system
has intervened three times
consecutively.
IMPORTANT When the tow hook is not in
use, put it in the closed position.
