Swivelling the tow ball in
WARNINGS
Keep your hands away from the
handwheel as it rotates during the
locking process.
You will hear a warning tone when
the tow ball arm is not in one of the
locked positions. If you do not hear
the tone when moving the tow ball arm,
do not use the tow bar and have it checked
by a properly trained technician.
CAUTION
Before retracting the ball neck into its
stowage position always unhitch the
trailer or dismantle load carriers and
their attachments. Dismantle attachments
for tracking stabilisation. Remove the plug
for the trailer power supply and the
adapter from the socket. Failure to do so
may result in damage to the bumper.
