WARNING■
Check that the ball head is seated correctly and is secured in the mount-
ing recess before starting any journey.■
Do not use the ball head if it is not correctly inserted in the mounting re-
cess.

hand injury.■
Keep your hands outside the operating lever's range of motion when at-
taching the ball head – there is a risk of finger injury.
■
Never attempt to pull the operating lever upwards forcibly to turn the
key. Doing so would mean the ball head is not attached correctly.

WARNINGNever allow the ball head to remain unsecured in the boot. This could
cause damage to the boot upon sudden braking, and could put the safety
of the occupants at risk.CAUTION■ If the operating lever B is held firm and not pushed downwards as far as it
can go, it will go back up after the ball head is removed and will not latch into
the ready position. The ball head then needs to be brought into this position
before the next time it is fitted » page 130, Adjusting the ready position .■
Place the tow bar in the standby position, with the key upwards, and store in
the box - otherwise there is a risk of damage to the key!
