Please observe the information concerning
Mercedes-Benz Genuine Parts (Ypage 33).
You can obtain further information from any
Mercedes-Benz Commercial Van Center.
GWARNING
The function of systems or components can
be affected by conversions or modifications
to the vehicle. They might not function prop-
erly anymore and/or jeopardize the opera-
tional safety of the vehicle. There is an
increased risk of an accident and injury.
Conversions or modifications should always
be carried out at qualified specialist work-
shop.
If you intend to make modifications to your vehi-
cle, we strongly recommend that you contact
the distributor named on the inside of the front
cover. There you will receive all the necessary
information and a charge may be levied.
You alone accept the responsibility if body man-
ufacturers or dealers make modifications that
affect the final certification of the engine, the
vehicle or the equipment. This also applies to
the identification and documentation of modifi-
cations to the affected vehicle components.
You are responsible for certification and confir-
mation that:
Rall the applicable standards and regulations
that are affected by the vehicle modification
are met
Rthe modified vehicle fulfills the vehicle safety standards and emissions laws and regula-
tions
Rthe modifications or installation of accesso-
ries does not affect the safety of the vehicle
We are not responsible for the final certification,
product liability or warranty claims which result
from the modifications. This applies to:
Rthe modified components, assemblies or sys-
tems
Rany resulting noncompliance with any of the
emissions laws and regulations or the motor
vehicle safety standards
Rany consequences arising from the changes
that make the vehicle less safe or even render it defective
We do not assume responsibility as the final-
stage manufacturer or for the consequential
product liability.
Notes on the radiator
Even seemingly small changes to the vehicle,
such as attaching a radiator trim for winter driv-
ing, is not permitted. Do not cover up the radi-
ator. Do not use thermal mats, insect protection
covers or anything similar.
Otherwise, the values of the diagnostic system
may be affected. Some of these values are
legally prescribed and must always be correct.
Genuine Mercedes-Benz parts
!
Air bags and Emergency Tensioning Devi-
ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
Rdoors
Rdoor pillars
Rdoor sills
Rseats
Rcockpit
Rinstrument cluster
Rcenter console
Do not install accessories such as audio sys-
tems in these areas. Do not carry out repairs or welding. You could impair the operating
efficiency of the restraint systems.
Have aftermarket accessories installed at a
qualified specialist workshop.
HEnvironmental note
We supply reconditioned assemblies and
parts which are of the same quality as new
parts. The same New Vehicle Limited War-
ranty applies as for new parts.
The operating safety of the vehicle could be
jeopardized if you use parts, tires and wheels as
well as accessories relevant to safety which
have not been approved by Mercedes-Benz. This could lead to malfunctions in safety-relevant
systems, e.g. the brake system. Only use genu-
ine Mercedes-Benz parts or parts of equal qual-
ity. Only use tires, wheels and accessories that
have been specifically approved for your vehi-
cle.

Ra malfunction in the electronics
XStop the vehicle immediately, paying attention to road and traffic
conditions, and switch off the engine.
!Do not continue driving. The engine could otherwise overheat.
XSecure the vehicle to prevent it from rolling away (Ypage 135).

An additional warning tone sounds. The coolant is too hot.
GWARNING
Never drive with an overheated engine. Driving when the engine is
overheated can cause fluids which may have leaked into the engine
compartment to catch fire.
In addition, steam from an overheated engine can cause serious
burns, which can occur just by opening the hood.
There is a risk of injury.
XStop the vehicle immediately, paying attention to road and traffic
conditions, and switch off the engine.
XSecure the vehicle to prevent it from rolling away (Ypage 135).
XWait until the engine has cooled down.
XMake sure that the air supply to the radiator is not obstructed, by
frozen slush for example.
XDo not start the engine again until the display message goes out and
the coolant temperature is below the maximum value specified. The
engine could otherwise be damaged.
XPay attention to the coolant temperature gauge (Ypage 175).
XIf the temperature increases again, visit a qualified specialist work-
shop immediately.
Under normal operating conditions and with the specified coolant
level, the coolant temperature gauge may rise to 248 ‡ (120 †).
?The fan motor is faulty.
XCheck the coolant temperature (Ypage 175).
XIf the coolant temperature is below the maximum value specified
below, you can continue driving to the nearest qualified specialist
workshop.
Avoid heavy loads on the engine, e.g. driving in mountainous terrain,
and stop-and-go traffic.
Under normal operating conditions and with the specified coolant
level, the coolant temperature gauge may rise to 248 ‡ (120 †).

?NThe red coolant warning lamp comes on while the engine is running.
The coolant level is too low.
If the coolant level is correct, the airflow to the engine radiator may be blocked or
the electric engine radiator fan may be malfunctioning.
The coolant is too hot and the engine is no longer being cooled sufficiently.
XObserve the display messages.
XStop the vehicle immediately, paying attention to road and traffic conditions,
and switch off the engine.
XSecure the vehicle to prevent it from rolling away (Ypage 135).
XExit the vehicle and keep a safe distance from the vehicle until the engine has
cooled down.
XCheck the coolant level and add coolant, observing the warning notes
(Ypage 255).
XIf you have to add coolant more frequently, have the engine cooling system
checked.
XMake sure that the air supply to the radiator is not obstructed, by frozen slush
for example.
XCheck the coolant temperature:
Rusing the display in the on-board computer on vehicles without steering wheel
buttons (Ypage 175)
Rusing the analog display in the instrument cluster on vehicles with steering
wheel buttons (Ypage 39)
XDo not start the engine again until the coolant temperature is below the maxi-
mum value specified below. The engine could otherwise be damaged.
XDrive to the nearest qualified specialist workshop.
Avoid heavy loads on the engine, e.g. driving in mountainous terrain, and stop-
start traffic.
Under normal operating conditions and with the specified coolant level, the cool-
ant temperature gage may rise to 248 ‡ (120 †).
?N The red coolant warning lamp comes on while the engine is running. An addi-
tional warning tone sounds.
The coolant temperature has exceeded the maximum value specified below. The
airflow to the engine radiator may be blocked or the coolant level may be too low.
GWARNING
The engine is not being cooled adequately and could become damaged.
Never drive with an overheated engine. Otherwise, fluids which may have leaked
into the engine compartment could catch fire.
In addition, steam from an overheated engine can cause serious burns, which can
occur just by opening the hood.
There is a risk of injury.
