222Driving and operatingTrailer towingTrailer loadsThe permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be
exceeded. The actual trailer load is
the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In
general, they are valid for gradients
up to 12%.
The permissible trailer load applies
up to the specified incline and at sea
level. Since engine power decreases
as altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross train weight also decreases by 10%
for every 1000 metres of altitude. The
gross train weight does not have to be reduced when driving on roads with
slight inclines (less than 8%, e.g.
motorways).The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 278.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load (85 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum load,
especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by
90 kg for the 5-door Hatchback/4-
door Saloon and 85 kg for the Sports
Tourer/Country Tourer, the gross
vehicle weight rating may be
exceeded by 65 kg for the 5-door
Hatchback/4-door Saloon and 60 kg
for the Sports Tourer/Country Tourer.
If the permissible rear axle load is exceeded, a maximum speed of
60 mph applies.
Towing equipmentCaution
The folding coupling ball bar
cannot be removed from the
vehicle. When driving without a
trailer, fold in the coupling ball bar.

Driving and operating2239Warning
Make sure that no one is in the
pivot zone of the coupling ball bar. Risk of body injury.
When releasing the stowed
coupling ball bar, make sure to
stand left of the grip.
Release stowed coupling ball bar
Pull the grip located left to the number
plate under the rear bumper fascia at an angle of approx. 45° to the ground.
A buzzing tone sounds as a warning
when the release handle is pulled out and the ball neck is disengaged.
Take the released coupling ball bar
and raise it up until it engages.
Ensure the coupling ball bar is
correctly engaged and the released
handle is guided back to its hidden
initial position, otherwise the buzzing tone will not stop.
Stow/hide coupling ball bar
Pull the grip located left of the number
plate under the rear bumper fascia at an angle of approx. 45° to the ground.

224Driving and operatingA buzzing tone sounds as a warning
when the release handle is pulled out and the ball neck is disengaged.
With the flat of the hand, swivel the
released coupling ball bar to the right
until it engages under the floor. Make sure that the release handle is back inits hidden initial position, otherwise
the buzzing tone will not stop.
9 Warning
Towing a trailer is permitted only
when the coupling ball bar is fitted correctly. If the coupling ball bar
does not engage correctly or if the
release handle is impossible to guide to its hidden initial position in the housing or if the buzzing tone
sounds after engaging the
coupling ball bar, seek the
assistance of a workshop.
Eye for break-away stopping cable
Attach break-away stopping cable to
eye.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While system is working keep steering wheel as still as possible.
Trailer stability assistant is a function
of the Electronic Stability Control
3 176.

3. Remove the electrical connectioncable and air hose from the
stowage compartments on the
underside of the compressor.
4. Screw the compressor air hose to
the connection on the sealant
bottle.
5. Fit the sealant bottle into the retainer on the compressor.
Set the compressor near the tyre
in such a way that the sealant
bottle is upright.
6. Unscrew valve cap from defective
tyre.
7. Screw the filler hose to the tyre valve.
8. The switch on the compressor must be set to J.
9. Connect the compressor plug to
the power outlet or cigarette
lighter socket.
To avoid discharging the battery,
we recommend running the
engine.
10. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to 6 bar whilstthe sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is inflated.

260Vehicle care13. The prescribed tyre pressureshould be obtained within
10 minutes. Tyre pressure
3 294 . When the correct pressure
is obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
10 minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button over the pressure indicator.
Do not run the compressor longer
than 10 minutes.
14. Detach the tyre repair kit. Push catch on bracket to remove
sealant bottle from bracket. Screw tyre inflation hose to the free
connection of sealant bottle. This
prevents sealant from escaping.
Stow tyre repair kit in load
compartment.
15. Remove any excess sealant using a cloth.
16. Take the label indicating maximum permitted speed from
the sealant bottle and affix in the
driver's field of view.
17. Continue driving immediately so that sealant is evenly distributedin the tyre. After driving approx.
6 miles (but no more than
10 minutes), stop and check tyre
pressure. Screw compressor air
hose directly onto tyre valve and
compressor when doing this.
If tyre pressure is more than 1.3 bar , set it to the correct value.
Repeat the procedure until there
is no more loss of pressure.
If the tyre pressure has fallen
below 1.3 bar, the vehicle must
not be used. Seek the assistance
of a workshop.
18. Stow away tyre repair kit in load compartment.
