Tighten the attachment screw for the pedal
bearing mount to its maximum point.
Secure both bicycle wheels to wheel
recesses using strap retainers.
Check the bicycle to make sure it is secure.
The settings for the wheel recesses and the
rotary lever on the pedal crank recess
should be noted and saved for each
bicycle. Correct presetting will facilitate
refitting of the bicycle. Removing a bicycle from the Flex-Fix
system
Undo strap retainers on both bicycle tyres.
Hold on to the bicycle, loosen the
attachment screw for the pedal bearing
mount, then lift the pedal bearing mount to
remove it.
Remove bicycle from the Flex-Fix system.
Retracting the Flex-Fix system
Push the pedal crank mounts into the
pedal crank recesses.

Swivel first the right clamping lever (1),
inwards, followed by the left clamping lever
(2), until they can be engaged in their
respective recesses.Push the clamping lever and pull both lamp
supports out of the recesses.
Fold in the lamp supports on the backs of
the tail lamps.
First place the right tail lamp (1), then the
left tail lamp (2) in their respective recesses
and push down as far as possible. Push
cables all the way into all guides in order to
prevent damage.

Pull up license plate holder and fold down
into horizontal position.Open the tailgate.
Raise the release lever
and push the system
into the bumper until it engages.
Ensure release lever returns to original
position.
Towing equipment 3
If the vehicle is not equipped with a trailer
hitch, we recommend having this
retrofitted by a workshop, who will advise
you on any possible towed load increases.
The workshop has instructions on how to
install the trailer hitch and making any
changes to the vehicle that are needed
that affect the coolin g system, heat shields
or other equipment.
Mounting dimensions of towing equipment
- see page 227.
9 Warning
If the system cannot be correctly
engaged, please contact a workshop for
assistance.
9 Warning
The coupling ball bar is to be removed
when not towing.

Towing equipment with detachable
coupling ball bar 3
Stowage of coupling ball bar
The coupling ball bar is kept in a bag,
fastened with a strap and is stowed below
the floor cover in the luggage
compartment.
Fitting the coupling ball bar
Remove sealing plug from the hole for the
coupling ball bar and stow it in the luggage
compartment. Confirm that the colour marking on the
lever is red.
Page 166 of 234

Driving and operation166
Inserting the coupling ball barInsert the coupling ball bar into the
coupling housing and push firmly
downwards until the coupling ball bar
audibly engages.
If it does not engage, repeat fitting
procedure.
Do not swing the coupling ball bar to the
left or right, or upwards and downwards, to
avoid disrupting correct fitting. Lock coupling ball bar by turning the
supplied key in the lock cylinder of the
coupling ball bar.
Remove key.Important
Check that the coupling ball bar is correctly
attached:
z
Green marking must be visible on lever.
z Coupling ball bar must be seated firmly
in coupling housing.
Coupling ball bar must be locked and key
must be removed.
Eye for breakaway stopping cable 3
In the case of caravans/trailers with
brakes 3, attach the breakaway stopping
cable to the eye - not the coupling ball bar.
9 Warning
Towing a caravan/trailer is only
permitted with a properly attached
coupling ball bar. If the coupling ball bar
cannot be properly attached, consult a
workshop.

Driving and operation167
Dismounting the coupling ball bar
Unlock coupling ball bar and remove key.
Push lever to the left, towards the coupling
ball bar and turn it downwards. Pull
coupling ball bar out of coupling housing.
Remove any rust or dirt from area around
the coupling housing and coupling ball bar
connection before inserting sealing plug in
the hole.
Place the coupling ball bar in the bag
supplied, fasten it wi th the strap and stow
it below the floor cover in the luggage
compartment.
Do not use steam-jet cleaners or other
high-pressure cleaners to clean the
coupling ball bar.
Towing
Caravan/trailer loads1)
The permissible caravan/trailer loads are
vehicle-dependent and engine-dependent
maximum values which must not be
exceeded.
The actual caravan/trailer load is the
difference between the actual gross weight
of the caravan/trailer and the actual
coupling socket load with the caravan/
trailer coupled.
When the caravan/trailer load is being
checked, therefore, on ly the caravan/trailer
wheels - and not the jockey wheel - must be
standing on the weighing apparatus.
The permissible caravan/trailer loads for
your vehicle are given in the vehicle papers.
Unless otherwise stated , they are valid for
gradients up to max. 12%.
The permissible caravan/trailer load should
be fully utilized only by drivers who are
adequately experienced in towing large
caravans/trailers.
The permitted caravan/trailer load applies
up to the specified incline and up to an
altitude of 1000 metres above sea level. Since engine power decreases as altitude
increases because of the air becoming
thinner, therefore reducing climbing ability,
it may not be possible for permissible trailer
loads to be fully utilized in mountainous
territory.
The permitted towing weight decreases by
10% for every 1000 metres of additional
altitude.
The towing weight does not have to be
reduced when driving on roads with slight
inclines (less than 8%, e.g. on motorways).
The actual caravan/trailer load plus the
actual Gross Vehicle Weight must not
exceed the maximum permitted towing
weight. For example, if the permitted Gross
Vehicle Weight is utilised, the caravan/
trailer load must only
be used until the
maximum permitted towing weight is
reached.
The maximum permitted towing weight is
shown on the vehicle id entification plate -
see page 215.
1)Observe national regulations.

Driving and operation168
Coupling socket load
The coupling socket load is the load
exerted by the caravan/trailer on the
coupling ball. It can be varied by changing
the weight distribution when loading the
caravan/trailer.
The maximum permissible coupling socket
load for the towing vehicle (80 kg) is stated
on the towing equipment identification
plate and should always be aimed for,
particularly in the case of heavy caravans/
trailers. The coupling socket load should
never be below 25 kg.
When measuring the coupling socket load,
make sure that the drawbar of the loaded
caravan/trailer is at the same height as it
will be when the carava n/trailer is coupled
with the towing vehicle loaded. This is
particularly important for caravans/trailers
with tandem axle. Rear axle load during towing
When the caravan/trailer is coupled and
the towing vehicle fully
loaded (including
all occupants), the permissible rear axle
load must not be exceeded.
National regulations regarding maximum
speeds for vehicles towing a caravan/
trailer must be observed.
Tyre pressure
Increase the tyre pressure on the towing
vehicle to the value specified for full load
(see page 224). Also check the pressure of
the caravan/trailer tyres.
