General notes
Important safety notes G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could
affect, for example, the power steering and
the brake boosting effect. You will require
considerably more effort to steer and brake.
There is a risk of an accident.
Do not switch off the ignition while driving. G
WARNING
Mobile communications equipment distracts
the driver from traffic conditions. In addi-
tion, the driver could lose control of the
vehicle. There is a risk of an accident.
As a driver, use mobile communications
equipment only when the vehicle is at a
standstill.
As a vehicle occupant, use mobile communi-
cations equipment only in the designated
area, e.g. the rear passenger compartment. Observe the legal requirements of the country
in which you are driving. Some jurisdictions
prohibit the driver from using a mobile phone
while driving a vehicle.
Always use the hands-free system for tele-
phoning while driving. Only use the telephone
if road traffic conditions permit. If this is not
the case, pull over to a safe location before
using the telephone.
Bear in mind that at a speed of just 30 mph
(approximately
50 km/h), your vehicle is cov-
ering a distance of 44 feet (approximately
14 m) every second.
Drive sensibly – save fuel In order to save fuel, observe the following
tips:
X The tires should always be inflated to the
recommended tire pressure.
X Remove unnecessary loads.
X Remove roof carriers when they are not nee-
ded.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service inter-
val display.
Fuel consumption also increases when driving
in cold weather, in stop-start traffic and in
mountainous terrain.
Overrun cutoff If you are in overrun mode and take your foot
off the accelerator pedal, the fuel supply is cut
off when the engine speed is out of the idle
speed control range.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal
accident is greatly increased when you drink
or take drugs and drive. 140
Driving tips
Driving and parking
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Emission control G
DANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Inhaling these exhaust gases is hazardous to
health and can result in poisoning. There is a
risk of fatal injury. Therefore, never leave the
engine running an enclosed space without
adequate ventilation.
Certain engine systems are designed to keep
the level of poisonous substances in exhaust
fumes within legal limits.
These systems only work optimally if they are
maintained exactly in accordance with the
manufacturer's specifications. Any work on
the engine should therefore be carried out by
qualified and authorized Mercedes-Benz tech-
nicians.
The engine settings must not be changed
under any circumstances. In addition, all spe-
cific maintenance work must be carried out at
regular intervals and in accordance with the
service requirements of the dealer listed here
on the inside title page. Details can be found
in the Maintenance Booklet. Speed limiter
G
WARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed
could lead to tire damage or the tire burst-
ing. There is a risk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe
the tire load rating and speed rating
required for your vehicle.
As the driver, you must be aware of the maxi-
mum design speed of the vehicle and the max-
imum permissible speed based on the tires
(tire and tire pressure). In particular, also observe the tire approval regulations for each
country.
You must not exceed the speed limit for the
tires indicated by the speed rating. The speed
rating is stated in the tire tables (Y page
302).
You can permanently limit the permissible
maximum speed of your vehicle, e.g. for driv-
ing on winter tires.
Mercedes-Benz recommends that you have
the maximum permissible speed programed at
a Mercedes-Benz Commercial Van Center.
Before overtaking, take into consideration that
the engine speed limiter prevents the speed
increasing beyond the programmed permissi-
ble 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 replace-
ment parts may not always be immediately
available. The relevant workshop directories
are available from any Mercedes-Benz Com-
mercial Van Center.
Fuel In some countries, only fuels with a higher sul-
fur content are available.
Unsuitable fuel can cause engine damage. You
will find information about fuel under "Service
products and capacities"
(Y page 306).
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 oncoming traffic from
being blinded. Symmetrical low beam does not
illuminate as large an area of the edge of the
road. Driving tips
