Mercedes-Benzrecommends that you have the
maximum permissible speed programed at a
Mercedes-BenzC ommercial Van Center.
Before overtaking, take into consideration that
the engine speed limiter prevents the speed
increasing beyond the programed maximum
speed.
Driving abroad
Service
An extensive network of authorized Mercedes-
Benz Centers is also at your disposal when you
are traveling abroad. Nevertheless, please bear
in mind that service facilities or replacement
parts may not always be immediately available.
The relevant workshop directories are available
from any Mercedes-BenzC ommercial Van Cen-
ter.
Fuel
In some countries, only fuels with ahigher sulfur
content are available.
Unsuitable fuel can cause engine damage. You
will find information about fuel under "Service
products and capacities" (
Ypage 296).
Low-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 low beam. This
prevents oncomingt raffic from being blinded.
Symmetrical low beam does not illuminate as
large an area of the edge of the road.
Vehicles with halogen headlamps
The headlamps do not need to be switched to
symmetrical low beam. The legal requirements
of countries in which traffic drives on the oppo- site side of the road to the countryw here the
vehicle is registered are met without the need to
convert the headlamps.
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 on this from any
Mercedes-BenzC
ommercial Van Center.
Brakes
Important safety notes
GWARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect,t he drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on aslippery road surface.
Downhill gradients
!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
This also applies to automatic braking if you
have activated cruise control.
On long and steep downhill gradients, you
should change down to shift range 2or1 in
good time (
Ypage 128).
This should be observed in particular when driv-
ing with aladen vehicle and when towing a
trailer.
You thereby make use of the braking effect of
the engine and do not have to brake as often to
maintain the speed. This relieves the load on the
service brake and prevents the brakes from
overheating and wearing too quickly.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as afootrest.N ever
depress the brake pedal and the accelerator
pedal at the same time.
