235Driving abroad
Points to remember
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's current telephone numbers
for use when you are abroad are to be found
in the "Service24h" chapter of the Service
Booklet.
Only low-octane fuel is available in certain
countries.
You can find further information about fuel
grades on (Y page 218). Symmetrical dipped beam
If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is
registered, your headlamps must be switched
to symmetrical dipped beam. Oncoming traf-
fic will be dazzled less.
X Have the headlamps switched over at a
qualified specialist workshop, e. g. a
Mercedes-Benz Service Centre. G
Risk of accident
Have your headlamps switched back to
asymmetrical dipped beam if you visit a country in which traffic drives on the same
side of the road as in the country in which
your vehicle was registered. You may oth-
erwise dazzle the oncoming traffic and
could cause an accident. Trailer towing*
Fitting the ball coupling
Before you can tow a trailer with your vehicle,
you must fit the ball coupling.
There is a key for the ball coupling.
X Make a note of the key number.
You can use this number to obtain a
replacement key from a Mercedes-Benz
Service Centre. G
Risk of injury
If the ball coupling does not engage cor-
rectly when it is fitted, the vehicle/trailer
combination will not be properly secured
and may detach. This could cause an acci-
dent. Fit the ball coupling carefully and
make sure that it engages correctly.
The detachable ball coupling is located in the
stowage well under the luggage compartment
floor.
The ball coupling recess is behind the cover
at the bottom of the bumper. Operation

lock.
X Remove the cause of the obstruction.
X Switch the windscreen wipers back on. The windscreen wipers fail com-
pletely. The windscreen wiper drive is
