General notes You can shift gears yourself using the steering
wheel gearshift paddles. The transmission must
be in position Dto do this.
Depending on which steering wheel gearshift
paddle is pulled, the automatic transmission
immediately shifts into the next gear up or
down, if permitted.
Mercedes-AMG vehicles: to use manual gear-
shifting, you have two options:
R temporary setting
R permanent setting
If you activate manual gearshifting, the multi-
function display will show the current gear
instead of transmission position D.
If you deactivate manual gearshifting, the gears will be shifted automatically again. 150

Protection against reaching the over-
revving range (Mercedes-AMG vehicles) !
In manual mode, the automatic transmis-
sion does not shift up automatically even
when the engine limiting speed for the current gear is reached. When the engine limiting
speed is reached, the fuel supply is cut to
prevent the engine from overrevving. Always
make sure that the engine speed does not
reach the red area of the rev counter. There is
otherwise a risk of engine damage. Before the engine speed reaches the red area,
an upshift indicator will be shown on the multi-
function display.
X When message :appears on the multifunc-
tion display, pull the right-hand steering
wheel gearshift paddle.
Kickdown X
For maximum acceleration, depress the
accelerator pedal beyond the pressure point.

reached.
During kickdown, you cannot shift gears using
the steering wheel gearshift paddles.
If you apply full throttle, the automatic trans-
mission shifts up to the next gear when the
maximum engine speed is reached. This pre-
vents the engine from overrevving.
Mercedes-AMG vehicles: kickdown is possible
only in the temporary setting. 152

WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refuelling. G
WARNING
Fuels are poisonous and hazardous to health. There is a danger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren. Refuelling
153Driving and parking
Z

If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek
immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. G
WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is a risk of
fire and explosion.
Always touch the vehicle body before opening the fuel filler flap or touching the fuel pump
nozzle. This discharges any electrostatic
charge that may have built up.
Do not get back into the vehicle during the refu-
elling process, otherwise electrostatic charge
could build up again. G
WARNING
Vehicles with a diesel engine:
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! Do not use diesel to refuel vehicles with a
petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel can
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, fuel can enter the fuel system. Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. The repair costs are high. Notify a
qualified specialist workshop and have the
fuel tank and fuel lines drained completely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when adding fuel from a fuel can.
The fuel lines and/or the fuel injection system could otherwise be blocked by particles fromthe fuel can.
If you overfill the fuel tank, some fuel may spray
out when you remove the fuel pump nozzle.
i Flexible-fuel vehicles can be identified by
the Ethanol up to E85 sticker on the inside of
the fuel filler flap.

cialist workshop.
Further information about BlueTEC exhaust gas
aftertreatment and about AdBlue ®
can
be obtained from any Mercedes-Benz Service
Centre.
Important safety notes AdBlue
®
is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
R non-toxic
R colourless and odourless
R non-flammable
If you open the AdBlue ®
tank, small amounts of
ammonia vapour may be released.
Ammonia vapours have a pungent odour and are
particularly irritating to the skin, mucous mem-
branes and eyes. You may experience a burning sensation in your eyes, nose and throat. You
may also experience coughing and watery eyes.
Do not inhale any ammonia vapours that may be
released. Fill the AdBlue ®
tank only in well-ven-
tilated areas. Do not swallow AdBlue
®
or let it come into con-
tact with your skin, eyes or clothing. Keep
AdBlue ®
away from children.
If you or others come into contact with AdBlue ®
,
observe the following:
R immediately rinse AdBlue ®
off your skin with
soap and water.
R if AdBlue ®
comes into contact with your eyes,
immediately rinse them thoroughly with clean water. Seek medical attention immediately.
R if AdBlue ®
is swallowed, immediately rinse
your mouth out thoroughly. Drink plenty of
water. Seek medical attention immediately.
R change immediately out of clothing that has
come into contact with AdBlue ®
.
! Only use AdBlue ®
in accordance with
ISO 22241. Do not mix any additives with
AdBlue ®
, and do not dilute AdBlue ®
with
water. This may destroy the BlueTEC exhaust
gas aftertreatment system.
! In order to fill the AdBlue ®
tank, the vehicle
must be parked on a level surface. The
AdBlue ®
tank can only be filled as intended
with the vehicle parked on a level surface.
Fluctuations in capacity will thus be avoided.
Filling a vehicle standing on an uneven sur-
face is not permitted. There is a danger of
overfilling, which can cause damage to Blue-
TEC exhaust gas aftertreatment components.
! Surfaces which have come into contact with
AdBlue ®
while refilling should be rinsed
immediately with water, or remove AdBlue ®
with a moist cloth and cold water. If AdBlue ®
has already crystallised, use a sponge and
cold water to clean the area. AdBlue ®
residue
crystallises after a certain amount of time and
soils the affected surfaces.
! AdBlue ®
is not a fuel additive and must not
be added to the fuel tank. If AdBlue ®
is added
to the fuel tank, this can lead to engine dam- age.
Have the AdBlue ®
tank refilled at a qualified
specialist workshop. However, you can also top
up the AdBlue ®
tank:
R at a filling station with an AdBlue ®
filling pump
R with AdBlue ®
refill bottles
R with an AdBlue ®
