Before overtaking, take into consideration that
the engine speed limiter prevents the speed
increasing beyond the programmed permissible
maximum speed.
On downhill gradients, the speed limitation may
be exceeded. Apply the brakes if necessary.
Display messages indicate that you are
approaching the limit speed.
Driving abroad
Service
An extensive network of Mercedes-Benz Service
Centres is also at your disposal when you are

may not always be immediately available. The
workshop directories are available from any
Mercedes-Benz Service Centre.

In some countries, only fuels with a higher sul-
phur content are available.

Dipped-beam headlamps
General notes
When driving in countries in which traffic drives
on the opposite side of the road to the country
where the vehicle is registered, you must switch
the headlamps to symmetrical dipped beam.
This prevents oncoming traffic from being daz-
zled. Symmetrical dipped beam does not illumi-
nate as large an area of the edge of the carria-
geway.
Vehicles with halogen headlamps
The headlamps do not need to be switched to
symmetrical dipped beam. The legal require-
ments of countries in which traffic drives on the
opposite side of the road to the country where
the vehicle is registered are met without the
need to convert the headlamps.
Vehicles with LED headlamps
For vehicles with steering wheel buttons, you
can switch over the dipped-beam headlamps via
the
Settings
menu in the on-board computer.
In the
Light
submenu, use the function
Dipped beams Setting for:
to switch
between
Right-side traffic
and
Left-
side traffic
(
Y
page 240).
Otherwise, or for vehicles without steering
wheel buttons, you can have the dipped-beam
headlamps switched over for right-side traffic or
left-side traffic at a qualified specialist work-
shop.
X
On your outbound journey, switch over the
dipped-beam headlamps before crossing the
border; on your return journey, switch the
headlamps back as close to the border as
possible.
If your vehicle's current setting differs from its
country specifications, then motorway mode
and the extended range fog lamps are unavail-
able.
Transport by rail
Transporting your vehicle by rail may be subject
to certain restrictions or require special meas-
ures to be taken in some countries due to vary-
ing tunnel heights and loading standards.
You can obtain information about this from any
Mercedes-Benz Service Centre.
