WARNING
Improper use of the towing bracket can
c
ause injury and accidents.
·
Only use the ball coupling when it is se-
cured correctly.
·
Never use the towing bracket if the
smallest diameter of the ball → Fig. 157
2 is less than 49 mm.
·
T
he ball coupling is heavy. When per-
forming the safety check, the ball cou-
pling could fall o and c
ause crush inju-
ries.
·
Do not touch the handwheel when the
ball coupling is pre-tensioned. When
the ball coupling is pressed into the
mounting, the handwheel will jump
back to its original position.
·
If the ball coupling cannot be attached,
have the towing bracket checked by
a qualified workshop.
·
Never use the towing bracket if the ball
coupling does not engage properly or
cannot be pre-tensioned.
·
Never use the ball coupling if the key in
the handwheel cannot be removed
when the ball coupling is fitted. This
means that the ball coupling is not
locked properly.
·
Always stow and secure the removed
ball coupling in the storage box under
the front right seat.
NOTICE
·
T
he mounting on the vehicle, handwheel,
shank and retaining balls of the ball cou-
pling must all be clean and undamaged.
Otherwise you may not be able to lock
the ball coupling securely.
·
Do not aim a high-pressure cleaner or
steam cleaner directly at the ball cou-
pling mounting. This could wash the
grease required for lubrication out of the
mounting.
NOTICE
The removable ball coupling is required for
towing. Make sure you alwa
ys carry the ball
coupling in the vehicle → page 307.
