stant orange glow.

IMPORTANT
When the tow bar is activated by pressing
a key and has been placed in the unlocked
position:
Wait at least 2 seconds before the tow bar

WARNING
Take care to secure the trailer's safety
cable in the intended bracket.
NOTE
Power save mode activates after a while
and the indicator lamp goes out. The sys-
tem is reactivated by closing and reopen-
ing the boot lid. This applies when retract-
ing or extending the towbar.
If the car detects a connected trailer elec-
trically, the indicator lamp stops illuminat-
ing with a constant glow.
Retracting the towbar
IMPORTANT
Make sure that there is no plug or adapter
in the electrical socket when retracting the
towbar.
1. Open the boot lid. Press and release the
button on the right-hand side at the rear of
the cargo area - retraction might not start
if the button is pressed for too long.
> The towbar automatically lowers in an
unlocked position - the indicator lamp
in the button flashes orange.
2.
Lock the towbar by moving it back to its
retracted position, where it is locked.
> The indicator lamp will now illuminate
with a constant glow if the towbar is
correctly retracted.
