! Refuel using only unleaded super grade
petrol with a minimum octane number of
98 RON/88 MON conforming to European
standard EN 228.
Otherwise, you could impair engine output
or damage the engine.
i If the recommended fuel is not available
and only as a temporary measure, you may
also use unleaded premium-grade petrol,
95 RON/85 MON. This may reduce engine performance and increase fuel consump-
tion. Avoid driving at full throttle.
In some countries, the fuel grade available
may not be adequate and could cause cok-
ing around the inlet valve. In such cases,
and in consultation with
aMercedes-Benz
Service Centre, the petrol may be mixed
with the additive recommended by
Mercedes-Benz( part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.
! In emergencies, and only when the rec-
ommended fuel is not available, you may
also use standard unleaded petrol,
91 RON/82.5 MON.
However, using this fuel results in consid-
erably higher petrol consumption and sig-
nificantly reduced engine output. Avoid
driving at full throttle.
If no fuel other than regular petrol with
91 RON/82.5 MON or a lower grade is per-
manently available, you should have the
vehicle adapted to run on this fuel by the
local after-sales service.
You can find further information about fuel on
(Y page 349). Engine compartment

not properly engaged. Open it again and
close it with a little more force. Engine oil
Depending on driving style, the vehicle con-
sumes a maximum of 0.8 l oil per 1000 km.
The oil consumption may be highert han this
when the vehicle is new or if you frequently
drive at high engine speeds.
Checking the engine oil level X
To check the engine oil, move the vehicle
to level ground. Switch off the engine at
normal operating temperature after run-
ning it in neutral for 30 seconds. X

obtained at a qualified specialist workshop,
e.g. from a Mercedes-Benz Service Centre.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanent SPEED-
TRONIC 19
(Y page 245) so that it does not
exceed the maximum permissible speed for
the winter tyres.
Once you have fitted the winter tyres:
X Check the tyre pressures (Y page 272).
X Restart the tyre pressure monitor
(Y page 273).
i Speeds of up to 240 km/h with winter
tyre variant 1: despite what is stated on the
tyre pressure information label (fuel filler
flap), for speeds up to 240 km/ha nd winter
tyre variant 1 (Y page 354), the tyre pres-
sures can be reduced:
R front −40 kPa (−0.4 bar)
R rear −60 kPa (−0.6 bar)
This improves the ride comfort of your vehi-
cle; however, the fuel consumption may
increase slightly. G
Ris
kofa ccident
If you fit the spare wheel* when driving with
winter tyres, bear in mind that driving stability
will be impaired owing to unstable cornering
characteristics caused by the differen ttyres.
You should therefore adapt your driving style
and drive carefully.
Have the spare wheel* replaced at the near-
est qualified specialist workshop which has
the necessary specialist knowledge and tools
to carry out the wor krequired. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose. In par-
ticular, work relevant to safety or on safety-
related systems must be carried out at a quali-
fied specialist workshop. Snow chains
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains which
have been specially approved for your vehicle
by Mercedes-Benz, or are of a corresponding
standard of quality.
If you intend to fit snow chains, please bear
the following points in mind:
R snow chains cannot be fitted to all wheel/
tyre combinations.
R snow chains must not be fitted to emer-
gency spare wheels, e.g. Minispare.
R fit snow chains only in pairs and only to the
rear wheels. Observe the manufacturer's
installation instructions.
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate ESP ®
when
pulling away with snow chains fitted
(Y page 47). This way you can allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action). Winter driving
G
Risk of accident
Do not shift down for additional engine brak-
ing on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Engage neutral.
X Try to bring the vehicle under control using
corrective steering.

Driving tips
Coasting wit
hthe engine switched off G
Risk of accident
Never switch the engine off while the vehicle
is in motion.
There is no power assistance for the steering
and the service brake whe nthe engine is not
running.
You will require considerably more effort to
steer and brake and you could therefore lose
control of the vehicle and cause an accident. Applying the brakes
G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
Risk of accident
Make sure that other road users are not
endangered by your braking.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden, you must shift to
a lower shift range in good time.
i This also applies if you have activated
cruise control or SPEEDTRONIC.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously.
Heavy and light loads If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but drive on for a short while. This allows the air-
flow to cool the brakes more quickly. G
Risk of accident
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet roads If driving in heavy rain for a prolonged period
of time without braking, there may be a
delayed reaction from the brakes when brak-
ing for the first time. This may also occur after
the vehicle has been washed.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehi-
cle washed, brake firmly while paying atten-
tion to the traffic conditions. This will warm
up the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salted
roads
G
Risk of accident
The layerofs alt on thebrake discs and the
brake pads/linings may caus eadelay in the
braking effect, resulting in a significantly lon-
ger braking distance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully, without put-
ting other road users at risk, when you are
driving on salted roads. This helps to Driving tips

waves. This may cause the maximum per-
missible water depth to be exceeded.
Failure to observe these notes may result
in damage to the engine, electrical systems
and transmission.
Driving abroad
Please bear the following in mind
An extensive Mercedes–Benz Service net-
work is also available in other countries. The
Service Hotline's curren ttelephone numbers
for use when you are abroad are to be found
in the "Service24h" chapter of the Service
Booklet.
Only low-octane fuel is available in certain
countries.
You can find further information about fuel
grades on (Y page 266). Symmetrical dipped-beam head-
lamps
G
Risk of injury
Xenon bulbs are under high voltage. You could
get an electric shock and be seriously or even
fatally injured if you touch the electric con-
tacts on xenon bulbs. Therefore, do not
remove the cover on xenon bulbs.
Do not change xenon headlamps yourself, but
have them replaced at a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop.
Switching to symmetrical dipped beam
when driving abroad: If your journey takes
you to countries where vehicles are driven on
the opposite side of the road to the country
in which the vehicle is registered, your head-
lamps must be switched to symmetrical
dipped beam. This prevents oncoming traffic
from being dazzled.
Before entering such countries, have the
headlamps switched over at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre, as close as possible to the
border. When using symmetrical lights, the
edge of the carriageway is not illuminated as
widely and as far ahead as normal.
Switching back to asymmetrical dipped
beam after your return: After returning from
such countries, have the headlamps switched
over at a qualified specialist workshop, e.g. a
Mercedes-BenzS ervice Centre, as close as
possible to the border. Service

rcare
Automatic car wash G
Risk of accident
Braking efficiency is reduced after washing
the vehicle. This could cause an accident.
After the vehicle has bee nwashed, brake
firmly while paying attention to the traffic con-
ditions. This will warm up the brake discs,
thereby drying them mor equickly. Afte rwash-
ing the vehicle, drive particularly carefully
until the brakes are dry and braking power has
been fully restored.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! When washing your vehicle in a tow-
through car wash, use the key instead of
the Start/Stop button.
Start the engine .Move the transmission
selector lever to N. Switch the engine off
again and make sure that you then leave
the key in position 2.You may otherwise
damage the vehicle, the transmission or
the car wash.
Check the transmission position in the
instrument cluster.
! Before switching off the engine, shift the
transmission to N. If you open the driver's
or front-passenger door, the transmission
remains in this position for up to 30
minutes if the key is in the ignition, even if
the engine is switched off. If you do not shift
the transmission to Nbeforehand, it shifts
automatically to parking position Pand
locks the wheels if the driver's or front-
passenger door is opened and the engine
is switched off. This may damage the vehi-
cle, the transmission or the car wash. !
Before driving into an automatic car wash,
make sure that it is suitable for the dimen-
sions of the vehicle. In particular, make
sure that:
R there is enough ground clearance
between the vehicle underbody and the
guide rails of the automatic car wash.
R the clearance width of the automatic car
wash is sufficient, particularly the width
of the guide rails
R you enter the automatic car wash
straight and in the centre of the guide
rails in order to avoid damaging the tyres
or wheel rims.
Fold in the exterior mirrors before the vehi-
cle is washed. The exterior mirrors could
otherwise be damaged.
! Make sure that the side windows are com-
pletely closed, that the ventilation/heater
blower is fully turned off and that the wind-
screen wiper switch is set to 0.Otherwise,
the rain/light senso rmay be activated, trig-
gering unintended wiper movements. This
could cause damage to the vehicle.
! In portal car washes, the windscree nwip-
ers may be moved up the windscreen by the
cleaning brushes when the ignition is
switched off.
Set the Start/Stop button to key position
2 to reset the windscreen wipers to their
original position.
! Vehicles with a mat tfinish*:
Do not use wash programs with a hot wax
treatment under any circumstances.
After using an automatic car wash, wipe off
wax and drying agents fro mthe windscreen
and the wiper blades. This will prevent smears
and reduce wiping noises caused by residue
on the windscreen. Care
