Important safet
ynotes G
WARNING
Only for the United Kingdom: if the vehicle
has been locked with the key or with KEY-
LESS-GO, the double lock function is activa-
ted as standard. It is then not possible to open
the doors from inside the vehicle.
Therefore, do not leave any people behind in
the vehicle, particularly children ,elderly peo-
ple or people requiring special assistance. As
ar esult, they may not be able to free them-
selves in the even tofanemergency. They
could be seriously or even fatally injured by
prolonged exposur etoextremely high or low
temperatures, for example. In this case, res-
cuing people from outside the vehicle is diffi-
cult.
Deactivate the interior motion senso rbefore
you lock the vehicle. The doors can then be
opened from the inside after the vehicle has
been locked from the outside. G
WARNING
If children are left unsupervised in the vehicle,
they could: R
open adoor from inside the vehicle at any
time, even if it has been locked
R start the vehicle using akey which has been
left in the vehicle
R release the parking brake
They could thereby endanger themselves and
others. Never leave children unsupervised in
the vehicle. Always take the key with you
when leaving the vehicle, even if you are only
leaving it for ashort time. G
WARNING
If ak ey ring is too heavy or too large, the
weight actin gonthe key could cause it to turn
in the ignition lock or catc honthe steering
wheel. This could cause the engine to be
switched off suddenly. You may lose control
of the vehicle and cause an accident. Do not
attac hany heavy or large key rings to the key
that is inserted in the ignition.
R Do not keep the key:
- with electronic devices, e.g. amobile
phone or another key
- with metallic objects, e.g. coins or metal
foil
- inside metallic objects, e.g. ametal case
This can affect the key's functionality.
Keep the key away from strong magnetic
fields. Otherwise, the remot econtrol function
could be affected. 76
KeyOpening and closing

There is
arisk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
If you switch off the ignition while driving,
safety-relevan tfunctions are only available
wit hlimitations ,ornotat all. This could affect,
for example, the power steerin gand the brake
boosting effect .You will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause afire
R lose its hold function.
There is arisk of fire and an accident .Release
the parking brake fully before driving off.
! Warm up the engine quickly. Do not use
the engine' sfull performance until it has
reached operatin gtemperature.
Only set the automatic transmission to the
respective drive position swhen the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train.
! AMG vehicles: at low engine oil temper-
atures (below +20 †), the maximum
engine speed is restricted in order to pro-
tectt he engine. To protec tthe engine and
maintain smoot hengine operation ,avoid
driving at full throttle when the engine is
cold. Key positions

off circuits. Always adapt your driving style to
suit the prevailing road and weather condi-
tions.
i RACE START is only available in AMG vehi-
cles.
RACE START enables optimum acceleration
from astanding start .The precondition for
this is asuitable high-grip road surface.
Activation conditions You can activat
eRACE START if:
R the doors are closed.
R the engine is running and it has reached an
operatin gtemperature of approximately
80 †. This is the case when the engine oil
temperature in the multifunction display
stops flashing.
R SPORT handling mode is activated

it with alittle more force. Radiator
Vehicles with adiesel engine: do not cover
the radiator .Donot use thermal mats, insect
protection covers or anything similar. Doing
so can cause the Onboard Diagnostics Sys-
tem to display inaccurate values. Some of
these values are legally required and must
always be correct. Engine oil
General notes Dependin
gonyour driving style, the vehicle
consumes up to 0.8 lofoil per 1,000 km. The
oil consumption may be higher than this when
the vehicle is new or if you frequently drive at
high engine speeds.
Dependin gonthe engine, the oil dipstick may
be installed at adifferent location.
When checking the oil level:
R park the vehicle on alevel surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly: wait about 30 minutes
before carrying out the measurement. Engine compartment

of carbon deposits. These will form especially
on the inlet valves and in the combustion
chamber.
This could lead to engine runnin gproblems,
e.g.:
R longer engine warm-up phase
R uneven idle
R engine noise
R misfiring
R loss of power
In areas where petrol with the required addi-
tives is not available, carbon deposits can
build up. In this case, Mercedes-Benz recom-
mends the use of additives that have been
approved for Mercedes-Benz vehicles; see
http://bevo.mercedes-benz.com.
The quality of the fuel available in some coun-
tries may not be sufficient .Residue could
build up as aresult. In such cases, and in
consultation with aMercedes-BenzS ervice
Centre, the petrol may be mixed with the
additive recommended by Mercedes-Benz
(part no. A000989254510). You must
observe the notes and mixin gratios specified
on the container.
Consult aMercedes-BenzS ervice Centreto
view alist of approved products. Observe the
instructions for use in the product descrip-
tion.
Do not mix other fuel additives with fuel. This
causes unnecessary cost sand could damage
the engine.
Diesel (EN 590) Fuel grade
G
WARNING
Do not use petrol to refuel vehicles with adie-
sel engine. Do not mix diesel with petrol. This
would result in damage to the fuel system and
engine, which could lead to avehicle fire.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590
or is of equivalent quality. Fuel that does not conform to EN 590 can lead to
increased wear as well as damage to the
engin
eand exhaust system.
! Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix such fuels with diesel fuel and
do not use any special additives. This can
otherwise lead to engin edamage. This
does not include flow improver additives.
For further information ,see "Flow improv-
ers".
! Vehicles with adiesel particle filter: in
countries outside the EU, only refuel with
low-sulphur Euro diesel with asulphur con-
ten tunde r50p pm; otherwise the emission
contro lsystem could be damaged.
! Vehicles without adiesel particle fil-
ter: in countries where only diesel fuel with
ah igh sulphur conten tisavailable, you will
need to carry out your vehicle's oil change
at shorter intervals. More information
aboutt he interval for oil change can be
obtained from any qualified specialist
workshop.
Usuallyy ou 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.
Information on refuelling (Y page 157).
Low outside temperatures
In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifi-
cations outlined in EN 590. At unusually low 362
