Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 28).Running-in notes
Important safety notes
G
WARNING
New brake pads/linings only have optimal
braking performance after several hundred
kilometres .Until then, compensate for this by
applying greate rforce to the brake pedal. This
also applies when brake pads/linings or
brake discs have been changed. The first 1,500 km
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R Therefore, drive at varying speeds and
engine speeds for the first 1,500 km.
R Avoid heavy loads on the engine during this
period, e.g. driving at full throttle.
R Change gear in good time, at the latest
when the rev counter needle is 2
/ 3 of the
way to the red area in the rev counter dis-
play.
R Do not manually shift to a lower gear to
brake the vehicle. Vehicles with automatic transmission:
R
If possible, do not depress the accelerator
pedal past the point of resistance (kick-
down).
R Only select shift ranges 3,2or 1when driv-
ing slowly, e.g. in mountainous terrain.
After 1,500 km, you may gradually bring the
vehicle up to full road and engine speeds.
Additional running-in notes for AMG vehicles:
R do not drive at speeds above 140 km/hf or
the first 1,500 km.
R only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
i You should also observe these notes on
running in if the engine or parts of the drive
train on your vehicle have been replaced. AMG vehicles with rear axle locking
differential
Your vehicle is fitted with a self-locking dif-
ferential on the rear axle. Change the oil after
a running-in period of 3,000 km to improve
protection of the rear axle differential. This oil
change extends the service life of the differ-
ential. Have the oil change carried out at a
qualified specialist workshop. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose. Driving
Important safety notes
G
WARNING
Do not place any objects in the driver's foot-
well. If you use a floormat or carpet in the
driver's footwell, make sure that it is correctly
secured and that there is sufficient clearance
for the pedals.
Do not place several floormats on top of one
another.
Loose objects or the floormats could other-
wise get caught between the pedals if you 152
DrivingDriving and parking

accelerate or brake suddenly. You will then
no tb e able to brake, declutch or accelerate
as intended. This could lead to accidents and
injury. G
WARNING
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. This could cause you
to lose control of your vehicle and cause an
accident.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when 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 tempera-
tures (below +20 †), the maximum engine
speed is restricted in order to protec tthe
engine. To protect the engine and maintain
smooth engine operation, avoid driving at
full throttle when the engine is cold. Key positions
Key g
To remove the key
1 Power supply for some consumers, such
as the windscreen wipers
2 Ignition (power supply for all consumers)
and drive position
3 To start the engine
If the key is at position 0in the ignition lock
for a longer period, it can no longer be turned
in the ignition lock. The steering is then
locked. To unlock it, remove the key and rein-
sert it into the ignition lock.
The steering wheel is locked when the key is
removed from the ignition lock.
i If the key does not belong to the vehicle
it can still be turned in the ignition lock.
However, the ignition will not be switched
on The engine cannot be started.
KEYLESS-GO General notes
Vehicles with KEYLESS-GO are equipped with
a key featuring an integrated KEYLESS-GO
function and a detachable Start/Stop button.
The Start/Stop button must be inserted into
the ignition lock and the key must be in the
vehicle.
Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal. Driving

Problems with the transmission
Problem Possible causes/consequences and
M Solutions
The transmission has
problems shifting gear. The transmission is losing oil.
X
Have the transmission checked at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service Centre, immediately. The acceleration ability
is deteriorating.
The transmission no
longer changes gear. The transmission is in emergency mode.
It is only possible to shift into
secondgear and reverse gear.
X Stop the vehicle.
X Shift the transmission to position P.
X Switch off the engine.
X Wait at least 10 seconds before restarting the engine.
X Shift the transmission to position Dor R.
If D is selected, the transmission shifts into secondgear; ifRis
selected, the transmission shifts into reverse gear.
X Have the transmission checked at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service Centre, immediately. Releasing the parking lock manually
In the event of an electrical fault, it is possible
to release the selector lever lock manually to
move it out of position P, e.g. if you wish to
tow the vehicle away. !
Do not use any sharp-edged objects to
remove the selector lever gaiter from the
centre console. This could damage the
selector lever gaiter.
X Apply the parking brake.
X Prise out selector lever gaiter :with a flat,
blunt object, (e.g. ascrewdriver wrapped in cloth) from the right-hand edge, pulling it
up and out.
X Press release button ;dow nand simul-
taneously move the selecto rlever out of

Important safety notes
G
WARNING
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine and the auxiliary heating
before refuelling. G
WARNING
Do not come into contact with fuels.
It is hazardous to your health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours. 168
RefuellingDriving and parking

However, using this fuel results in consid-
erably higher petrol consumptio
nand sig-
nificantly reduced engine performance.
Avoid driving at full throttle.
If no fuel othe rthan 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 in a
qualified specialist workshop. Mercedes-
Benz recommends that you use a
Mercedes-Ben zService Centre for this pur-
pose.
C 350 BlueEFFICIENCY and C 350
4MATIC BlueEFFICIENCY !
Only refuel using unleaded, sulphur-free
premium-grade petrol with at least
95 RON/85 MON, which conforms to Euro-
pean standard EN 228 or an equivalent
specification.
You can otherwise impair engine output or
damage the emission control system.
i In some countries, the available petrol
may not be sufficiently low in sulphur. This
fuel can temporarily produce unpleasant
odours, especially on short journeys. As
soon as sulphur-free fuel (sulphur content
<10p pm) is used for refuelling, the odours
are reduced. Diesel (EN 590)
Fuel grade !
When refuelling, only use diesel fuel that
conform stothe European standard EN 590
or is of equivalent quality. You can other-
wise impair engine output or damage the
engine.
! Vehicles with diesel particle filters: in
countries outside the EU, only use low sul-
phur Euro diesel with a sulphurc ontent of
under 50 ppm. Otherwise, the emission
control system could be damaged. !
Vehicles without adiesel particle fil-
ter: in countries where only diesel fuels
with a higher sulphur conten tare available,
the vehicle's oil change intervals are
shorter. More information about intervals
for changing the oil can be obtained from
any Mercedes-Benz Service Centre.
! Only use fuel that complies with the EN
590 European standard .Fuel that does not
comply with EN 590 can lead to increased
wear, engine damage and damag eto the
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 these fuels with diesel fuels and
do not use any special additives. Other-
wise, this can lead to damage to the engine.
This excludes flow improver; see "Low out-
side temperatures".
! Use a filter when adding fuel from a fuel
can. Otherwise, the fuel lines and/or the
diesel injection system could be blocked by
particles from the fuel can.
For further information on "Fuel", see
(Y page 380).
Low outside temperatures Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
perature classes are defined in EN 590. Refu-
elling with diesel fuel which complies with the
climatic specifications of standard EN 590
can help to prevent operating problems. At
exceptionally low temperatures, it is possible
that the flow properties of the fuel may be
inadequate. This also applies to fuel that has 170
RefuellingDriving and parking

not been adapted to suit the climatic condi-
tions, e.g .diesel fuel fro mwarmer regions.
i Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g .atfilling stations.
Flow improver Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective-
ness of a flow improver is not guaranteed with
every diesel fuel.
Correct dosage and thorough mixing are deci-
sive factors in ensuring improvement in low-
temperature resistance. Avoid excessive dos-
age. Excessive dosage may actually decrease
low-temperature resistance under certain cir-
cumstances. Follow the manufacturer's dos-
ing instructions.
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Malfunctions can other-
wise only be rectified by heating the entire
fuel system, e.g. by parking the vehicle in a
heated garage.
Observe the information provided by the man-
ufacturer when using a flow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
further information from any Mercedes-Benz
Service Centre. Refuelling
