tracted from the traffic conditions, cause an
accident and injure yourself and others.
Two-way radios and fax equipment used with-
out low-reflection exterior aerials can inter-
fere with the vehicle's electronics and thereby
jeopardise the operating safety of the vehicle
and yours afety. Therefore, you must only use
this equipment if it is correctly connected to
a separate reflection-free exterio raerial. G
WARNING
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior aerial takes
into account current scientific discussions
relating to the possible health risk posed by
electromagnetic fields.
Mercedes-Benz recommends the use of an
approved exterior aerial. This ensures:
R optimal mobile phone reception quality in
the vehicle
R mutual influences between the vehicle
electronics and mobile phones are mini-
mised
An exterior aerial has the following advan-
tages:
R it conducts the electromagnetic fields gen-
erated by a wireless device to the exterior.
R the field strength in the vehicle interior is
lower than in a vehicle that does not have
an exterior aerial.
i There are various mobile phone brackets
that may be fitted in your vehicle; in some
cases, these are country-specific. You can
obtain these mobile phone brackets from a
qualified specialist workshop.
The functions and services available when
you use the phone depend on your mobile
phone model and service provider. Mobile telephone bracket in the stow-
age space

Checking the oil level using the oil dip-
stick
Example
:oil dipstick
On the G 65 AMG, the oil level can be checked
using the on-board computer only.
On all other models, the dipstick must be
used to chec kthe engine oil level.
When checking the oil level:
R park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R the engine should be switched off for at
least 30 minutes if the engine is not at
operating temperature (i.e. if you only start
the engine briefly).
X Pull oil dipstick :out of the oil dipstick
tube.
X Wipe off oil dipstick :.
X Slowly slide oil dipstick :into the guide
tube to the stop, and take it out again.
The oil level is correct if the level is between
MIN mark =and MAX mark ;.
X Top up the oil if necessary.
Checking the oil level using the on-
board computer !
Do not add too much oil. Topping up with
too much engine oil can result in damage
to the engine or to the catalytic converter.
Have excess engine oil siphoned off.
G6 5 AMG: the oil level can be checked using
the on-board computer only. On all other models, the dipstic
kmust be
used to chec kthe engine oil level.

General notes
! For safety reasons, Mercedes-Benzr ec-
ommends that you only use tyres, wheels
and accessories which have been approved
by Mercedes-Benzs pecifically for your
vehicle. These tyres have been specially
adapted for use with the driving safety sys-
tems, such as ABS or ESP ®
.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz .Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with aload, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components.T his could result in dam-
age to the tyres or the vehicle.
Mercedes-Ben zaccepts no liability for
damage resulting from the use of tyres,
wheels or accessories othe rthan those tes-
ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any Mercedes-Benz Service
Centre.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as a result of driving over obstacles
increases.
i You will find a table of tyre pressures on
the inside of your vehicle's fuel filler flap. For further information on tyre pressure,
see (Y
page 325). Check tyre pressures
regularly and only when the tyres are cold.
i Notes on the vehicle equipment –always
fit the vehicle:
R with tyres of the same size on a given axle
(left/right)
R fit the same type of tyres on your vehicle
at a given time (summer tyres, winter
tyres, all-weather tyres, All Terrain tyres)

Fuel grade
!
Do not use diesel to refuel vehicles with a
petrol engine. Even asmall quantity of die-
sel will damage the fuel injection system.
! Only refuel using unleaded petrol with at
least 95 RON/85 MON that conforms to European standard EN 228 or E DIN
51626-1 or an equivalent specification.
Fuel with this specification may contain up
to 10 % ethanol.
! Do not use the following:
R E85 (petrol with 85 % ethanol)
R E100 (100 %ethanol)
R M15 (petrol with 15 % methanol)
R M85 (petrol with 85 % methanol)
R M100 (100 % methanol)
R Petrol with metallic additives
R Diesel
Do not mix these fuels with petrol, and do
not use any additives. This can otherwise
lead to engine damage. This does not
include cleaning additives for the removal
and prevention of residue build-up. Only
cleaning additives recommended by
Mercedes-Benzs hould be added to petrol,
see "Additives". You can obtain further
information from any Mercedes-Benz
Service Centre.
! Use a filter when adding fuel from a fuel
can. The fuel lines and/or the diesel injec-
tion system could otherwise be blocked by
particles from the fuel can.
Usually you will find information about the
fuel grade on the pump. If you cannot find the
label on the petrol pump, ask the filling sta-
tion staff.
i E10 fuel contains up to 10% bioethanol.
Your vehicle is suitable for use with E10
fuel. You can refuel your vehicle using E10
fuel.
i As a temporary measure, if the recom-
mended fuel is not available, you may also
use unleaded petrol with an octane rating
of 91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.

AdBlue
®
General notes AdBlue
®
is a non-flammable, non-toxic, col-
ourless, odourless and water-soluble fluid.
High outside temperatures If you open the AdBlue
®
tank cap, small
amounts of ammonia vapour may be
released.
Ammonia vapours have a pungen todour and
are particularly irritating to:
R skin
R mucous membranes
R eyes
You may experience a burning sensation in
your eyes, nose and throat, as well as cough-
ing and watering of the eyes.
Do not inhale any ammonia vapours that may
be released. Fill the AdBlue ®
tank only in well-
ventilated areas.
Low outside temperatures AdBlue
®
freezes at a temperature of approx-
imately -11 †. The vehicle is equipped with
an AdBlue ®
preheating system at the factory.
Winter operation can therefore be guaran-
teed even at temperatures below -11 †.
Additives !
Only use AdBlue ®
in accordance with ISO
22241. Do not use additives with AdBlue ®
and do not dilute AdBlue ®
with water. This
may destroy the BlueTEC exhaust gas after-
treatment system.
Purity !
Impurities in AdBlue ®
(e.g. due to other
service products, cleaning agents or dust)
lead to:
R increased emission values
R damage to the catalytic converter R
engine damage
R malfunctions in the BlueTEC ®
exhaust
gas aftertreatment system
Assuring the purity of AdBlue ®
is particularly
important with respec ttoavoiding malfunc-
tions in the BlueTEC exhaust gas aftertreat-
ment system.
If AdBlue ®
is pumped out of the AdBlue ®
tank,
e.g. during repair work, do not use this fluid
to refill the tank. The purity of the fluid can no
longer be guaranteed.
