It is hazard
oustoy our health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours. G
Risk of fire
Do not use petrol to refuel vehicles with adie-
sel engine. Never mix diesel with petrol. This
causes damage to the fuel system and engine
and could result in the vehicle catching fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with apetrol engine. Even asmall
quantity of th ewrong fue lwill damage the
fuel system and engine.
! If the wrong fuel has been added by mis-
take, do not switch on the ignition .Ifyou
do, the fuel coul denter the fuel lines .The
fuel tan kand the fuel lines must then be
drained .Inform aqualified specialist work-
sho pand have the fuel tank and the fuel
lines drained comple tely. Petrol (EN 228)
Fuel grade !
Only refuel using unleaded premium-
grade petrol with at least
95 RON/8 5MON, whic hconforms to Euro-
pean standar dEN2 28.
Yo uc an otherwise impair engine output or
damage the engine.
! Do not use the following:
R E85 (petrol with 85 %ethanol)
R E10 0(100 %ethanol)
R M15 (petro lwith 15 %methanol)
R M85 (petrol with 85 %methanol)
R M10 0(100 %methanol)
R diesel
Do not mix these fuel swith petrol and do
not use any special additives. Otherwise,
this can lead to damage to the engine. This
does not include additives for the removal and prevention of residue build-up on the
inlet valves.
i If the recommended fuel is not available,
but only as atemporary measure, you may
also use regula runleaded petrol,
91 RON/82.5 MON. Thi smay reduce
engine performance and increase fuel con-
sumption. Avoid driv ingatf ull throttle.
In some countries, the fuel grad eavail able
may not be adequate and could cause res-
idu etob uild up around the inlet valve. In
such cases, and in consultation with a
Mercedes-Benz Service Centre, the petrol
may be mixed with the additive recommen-
ded by Mercedes-Benz (part no.
A000989254510). You must observe the
note sand mixing ratios specified on the
container.
For further information on "Fuel" ,see
(Y page 313). Diesel (EN 590, DIN 51628)
Fuel grade !
Only refuel with diesel that conform sto
Europea nstandard EN 590 or German
standard DIN 5162 8orthe equivalent. You
can otherwise impair engin eoutput or dam-
age the engine.
! Vehicles with diesel particle filters: in
countries outsid ethe EU ,only use low sul-
phu rEuro diesel with asulphu rcontent of
under 50 ppm. Otherwise, the emission
con trol system coul dbedamaged.
! Vehicles without adiesel particle fil-
ter: the engin eoil should be changed more
frequently in countries in which diesel with
ah igher sulphur conten tisavailable .More
information about intervals for changing
the engin eoil can be obtained from any
Mercedes-Benz Service Centre.
! Using fuel that does not confor mtoEuro-

Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle when the key is removed.
Never leave children unsupervised in the vehi-
cle. They could release the parking brake. This
could lead to aserious or fatal accident. G
Risk of fire

under any circumstances com einto contact
with easily ignitable material such as dry grass
or petrol .Otherwise, the flammable material
may ignite and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be appl ied.
R on vehicles wit hmanual transmission,
engage first gear or reverse gear.
R on vehicles with automatic transmission,
the transmissio nmust be in position Pand
the key must be removed from the ignition
lock.

Important safety notes G
Risk of accident
PARKTRONIC is only an aid and may not
detect all obstacles .This system does not
reliev eyou of the need to pay attention.
You are always responsible for safet yand
must continue to pay attention to your imme-
diate surroundings whe nparking and
manoeuvring. You could otherwise endanger
yourself and others. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise ,they
coul dbei njured.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visual lyand
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R release the parking brake
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper. 174

X Switch the ignition back on. The problem may be caused by an exter
nalsource of radio or
ultrasoun dwaves.
X See if PARKTRONIC functions in adifferent location. Parking Guidance
Important safet ynotes Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to meas-
ure the road on both sides of the vehicle. A
suitable parking space is indicated by the
parking symbol. You receiv esteering instruc-
tions when parking. You may also use PARK-
TRONIC (Y page 174). G
Risk of accident
Parking Guidance is merely an aid and may
recommen dparking spaces that are not suit-
able for parking. For example, these might be
spaces where parking is prohibited ,drive-
ways, unsuitabl esurfaces, etc.
Parking Guidance measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Parking Guidance does not relieve you of the
responsibility for paying attention. If you rely
solely on Parking Guidance, you could cause
an accident and injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring.
G
Risk of accident
Objects located above the height range of
Parking Guidance will not be detected when
the parking space is measured. Thes eare not
take ninto account whe nthe parkin gproce-
dure is calculated, e.g .overhanging loads ,tail
sections or loading ramps of good svehicles.
