Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.
Always specify the vehicle identification num-
ber (VIN) (Y page 382) and the engine num-
ber (Y page 383) when ordering genuine
Mercedes-Ben zparts. Vehicle electronics

WARNING
Always have work on the engine electronics
and related components carried out at a quali-
fied specialist workshop. Otherwise, the vehi-
cle's operating safety could be affected.
! Only have work carried out on the engine
electronics and its associated parts, such
as control units, sensors and connector
leads, at a qualified specialist workshop.
Vehicle components may otherwise wear
more quickly and the vehicle's operating
permit may be invalidated. Retrofitting of two-way radios and
mobile phones (RF transmitters)
Use the Technical Specification
ISO/TS 21609 41
implementation regulation
when retrofitting RF (radio frequency) trans-
mitters.
If your vehicle has fittings for two-way radio
equipment, use the power supply or aerial
connections intended for use with the basic
wiring. Be sure to observe the manufacturer's
additional instructions when installing. !
Have aftermarket radio frequency trans-
mitting equipmen tinstalled at a qualified
specialist workshop.
The transmission outpu tatthe aerial base
must not exceed the maximum values below. Waveband Maximum
transmission
output (PEAK) Short wave (f < 54 MHz) 100 W

!
Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB Specifications for
Service Products 310.1, e.g. on the Inter-
net at http://bevo.mercedes-benz.com.
Or contact a qualified specialist workshop.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
! The engine cooling system is filled with
coolant, which must be renewed after
15 years or after 250,000 kilometres at the
latest.
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point of
the coolant during operation will be around
130 †.
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
R be at least 50%. This will protect the engine
cooling system against freezing down to
around -37 †.
R not exceed 55% (antifreeze protection
down to -45 †). Otherwise, heat will not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Benz recom-
mends an antifreeze/corrosion inhibitor con-
centrate in accordance with MB Specifica-
tions for Service Products 310.1. The coolant is checked with every mainte-
nance interval at a qualified specialist work-
shop.
i
When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion. Washer fluid
G
WARNING
Windscreen washer fluid/antifreeze is highly
flammable. Avoid spilling windscreen washer
fluid/antifreeze on hot engine components as
it can ignite and burn. Severe burns could be
the result.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or
MB WinterFit. Unsuitable washer fluid
could damage the plastic lenses of the
headlamps.
! Do not use distilled or de-ionised water in
the washer fluid reservoir. Otherwise, the
level sensor may be damaged.
! Only the washer fluids SummerFit and
WinterFit can be mixed. Otherwise, the
spraying nozzles could become blocked.
At temperatures above freezing:
X Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB Sum-
merFit.
X Mix 1 part MB SummerFit to 100 parts
water.
At temperatures below freezing:
X Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB Winter-
Fit. Adapt the mixing ratio to the outside
temperatures.
X Down to Ò10 †: mix 1 part MB WinterFit to
2 parts water. Service products and capacities

24 GHz radar sensor system (country overview)
The 24 GHz radar senso rsystem requires separat eapproval for each country. If you are driving
in a country in which the radar senso rsystem is no tapproved, you must deactivate the system
using the on-board computer (Y page 247). The current country overview can be obtained
from a Mercedes-Benz Service Centre.
Vehicles with anavigation system: the radar sensor system is deactivated automatically
near radio telescope facilities.
The currently active systems are automatically deactivated:
R DISTRONIC PLUS (Y page 185)
R Blind Spot Assist (Y page 212)
R Active Blind Spot Assist(Y page 216)
R PRE-SAFE ®
Brake (Y page 75)
Ad isplay message appears in the multifunction display to tell you that the radar sensor system
is being switched off (Y page 268).
BAS PLUS (Y page 70) is the nalso unavailable.
If the deactivation does not occur automatically, you must deactivate the radar sensor system
using the on-board computer (Y page 247).
Vehicles withou tnavigation and vehicles for Australia: you must deactivate the radar
sensor system using the on-board computer whe nyou are near a radio telescope facility
(Y page 247). Country Radio telescope
