that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affec-
ted by these factors:
R operating conditions of your vehicle
R your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R avoid short trips as these increase fuel
consumption.
R always make sure that the tire pressures
are correct.
R do not carry any unnecessary weight.
R remove roof racks once you no longer
need them.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R do not depress the accelerator pedal
when starting the engine.
R do not warm up the engine when the vehi-
cle is stationary.
R drive carefully and maintain a safe dis-
tance from the vehicle in front.
R avoid frequent, sudden acceleration and
braking.
R change gear in good time and use each
gear only up to Ô of its maximum engine
speed.
R switch off the engine in stationary traffic.
R keep an eye on the vehicle's fuel con-
sumption. Environmental issues and recom-

Introduction

Modifying the engine output
! Increases in engine power can:
R change the emission values
R cause malfunctions
R cause consequential damage
The operating reliability of the engine is not
guaranteed in all cases.
Any tampering with the engine management
system in order to increase the engine power
output will lead to the loss of the New Vehicle
Limited Warranty and other warranty entitle-
ments.
If you sell the vehicle, inform the buyer of any
alterations to the vehicle's engine power out-
put. If you do not inform the buyer, this may
constitute a punishable offense under national
legislation. Qualified specialist workshop
A Mercedes-Benz Commercial Van Center is a
qualified specialist workshop.
A qualified specialist workshop has the neces-
sary specialist knowledge, tools and qualifica-
tions to carry out the work required on the
vehicle correctly.
This is particularly applicable to work relevant

conversions
R work on electronic components
Mercedes-Benz recommends that you use a
Mercedes-Benz Commercial Van Center.
! Have the engine electronics and associ-
ated parts, such as control units, sensors,
actuating components or electric cables
serviced only at a qualified specialist work-
shop. Vehicle components may otherwise
wear more quickly and the vehicle's operat-
ing permit may be invalidated. Problems with your vehicle
If you should experience a problem with your
vehicle, particularly one that you believe may
affect its safe operation, we urge you to con-
tact a Mercedes-Benz Commercial Van Center-

Introduction

In some countries, certain parts are only offi-
cially approved for installation or modification
if they comply with legal requirements. All gen-
uine Mercedes-Benz parts satisfy these
requirements. Make sure that all parts are
suitable for your vehicle.
Always specify the vehicle identification num-
ber (VIN) ( Y page
304) and engine number
when ordering genuine Mercedes-Benz parts
(Y page 305). QR code for rescue card
The QR Code stickers are affixed to the B-pillar
on the driver's and front-passenger side.
In the event of an accident the rescue services
use the QR Code to quickly find the rescue
card for your vehicle. The current rescue card
contains the most important information on
your vehicle, e.g. the electric cable routes, in a
compact form.
Further information can be found at http://
www.mercedes-benz.de/qr-code. Data stored in the vehicle
Electronic control units
Electronic control units are installed in your
vehicle. Some of them are necessary to ensure
that your vehicle functions safely, some are
there to support the driver (driver assistance
systems). In addition to that, your vehicle
offers convenience and entertainment func-
tions which are also made possible by the use
of electronic control units.
Electronic control units contain data memories
which can store technical information on the
vehicle's operating state, component stress,
maintenance requirements as well as technical
events and malfunctions either temporarily or
permanently.
In general, this information documents the sta-
tus of a component, a module, a system or the
surroundings, for example:
R operating states of system components (e.g.
fill levels, battery status, tire pressure)
R status messages concerning the vehicle or
its individual components (e.g. number of
wheel revolutions/speed, deceleration in movement, lateral acceleration, display of
fastened seat belts)
R malfunctions and defects in important sys-
tem components (e.g. lights, brakes)
R information on events damaging the vehicle
R system responses in special driving situa-
tions (e.g. air bag deployment, intervention
of stability control systems)
R ambient conditions (e.g. temperature, rain
sensor)
In addition to the underlying control unit func-
tion, this data can be used for the detection
and the rectification of malfunctions as well as
the optimization of vehicle functions by the
manufacturer. Most of this data is volatile and
is only processed in the vehicle itself. Only a
small proportion of the data is stored in event
or malfunction memories.
When you use services, the technical data
from the vehicle can be read out by service
network employees (e.g. workshops, manufac-
turers) or third parties (e.g. breakdown serv-
ices). Services can include repair services,
maintenance processes, warranty cases and
quality assurance measures. Data is read out
using the legally prescribed diagnostics con-
nection in the vehicle. The respective repre-
sentatives of the service network or third par-
ties collect, process and use the data. It docu-
ments technical states of the vehicle, helps
staff to find malfunctions and improve quality
and, in certain cases, is passed on to the man-
ufacturer. Furthermore, the manufacturer is
subject to product liability provisions. For this
reason, the manufacturer requires technical
data from vehicles.
Malfunction memories in the vehicle can be
reset within the scope of the repair or service
work carried out by a service outlet.
Depending on the equipment selected, you
can add data to the convenience and infotain-
ment functions of the vehicle yourself.
These include:
R multimedia data, such as music, films or
photos for playback in an integrated multi-
media system
R address book data for use in connection
with an integrated hands-free system or an
integrated navigation system
R navigation destinations entered
R data on the utilization of Internet services Introduction

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions rel-
evant to safety.
Read the information on qualified specialist
workshops (Y page
32).Overview of climate control systems
Important safety notes
Observe the recommended settings on the fol-
lowing pages. Otherwise, the windows could
fog up.
To prevent the windows from fogging up:
R only switch off climate control briefly
R only switch on air-recirculation mode briefly
R for vehicles with air-conditioning system or
dual-zone automatic climate control, switch
on the "Cooling with air dehumidification"
function
R for vehicles with dual-zone automatic cli-
mate control, switch on the windshield
defrosting function briefly, if required Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.
Climate control is only operational when the
engine is running. The system only functions
optimally when the side windows are closed.
Ventilate the vehicle for a brief period during
warm weather. In order to cool the vehicle
more rapidly, switch climate control to air-
recirculation mode briefly. This will speed up
the cooling process and the desired interior
temperature will be reached more quickly.
The integrated filter can filter out most parti-
cles of dust and completely filters out pollen.
In vehicles with dual-zone automatic climate
control, gaseous pollutants and odors will also
be reduced. A clogged filter reduces the air-
flow into the vehicle interior. For this reason,
you should always observe the interval for
replacing the filter, which is specified in the
Maintenance Booklet. As the interval between
changes depends on environmental condi-
tions, e.g. heavy air pollution, the interval may
be shorter than stated in the Maintenance
Booklet. 114
