sioned. The red marking 13 on the
handwheel must point towards the
white marking 11 on the ball coupling.
T
he handwheel protrudes clearly from
the ball coupling. The gap between
them is approximately 4 mm

tep 3: attaching the pre-tensioned ball
coupling to the vehicle.
Do not touch the handwheel once the ball
coupling has been pre-tensioned. When
engaged, the handwheel will spring back to
its original position and could cause injury
→
.
1.
Guide the pre-tensioned removable ball
coupling into the mounting for the ball
coupling from below.
2. Push the ball coupling firmly upwards
until it engages. Both centring devices
→ Fig. 159
5 must engage in the
mounting points on the vehicle.
3.
T
he handwheel → Fig. 159
9 has now
returned to its original position. T
here is
no longer a gap between the hand-
wheel and the ball coupling.
4.
Turn the key → Fig. 159
8 in the hand-
wheel clockwise and remove it.
5.
T
he handwheel → Fig. 159
9 may now
no longer be pulled out.

.
Fit the lock cap → Fig. 159
7 on the
lock and pla
ce the key in the stowage
box.
7. Secure the stowage box under the
right-hand front seat.
Step 4: safety check.
Before hitching a trailer, check that the ball
coupling is secured correctly.
1.
The green marking → Fig. 159
12 on the
handwheel must point towards the
white marking on the b
all coupling
11 .
2.
T
he handwheel → Fig. 159
9 must rest
on the b
all coupling and there must be
no gap between them.
3. Shake or pull down on the ball coupling
→ Fig. 15
9 with some force. It must sit
firmly in the mounting →
.
4
. The lock must be locked and the
key → Fig. 159
8 removed.
5.
T
he lock cover → Fig. 159
7 must cover
the lock in the handwheel.
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. 159
2 is less than 49 mm (1.9 in).
·
T
he ball coupling is heavy. When per-
forming the safety check, the ball cou-
pling could fall o and cause 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 it is not possible to fit the ball cou-
pling, have it checked by a suitably
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
Incorrect cleaning of the vehicle could
dama
ge seals or wash o the grease re-
quired for lubrication.
·
Never aim the jet of a high-pressure
cleaner or steam cleaner directly at the
ball coupling or the fitted trailer socket.
The removable ball coupling is re-
quired for towing. Make sure you al-
