The horn will also sound at regular intervals if
Distronic Plus is activated and you:
R
switch off the engine, open the driver's
door and remove your seat belt.
R open the bonnet.
The sounding of the horn alerts you to the fact
that the vehicle has been parked while Dis-
tronic Plus is still activated. The sound
becomes louder if you attempt to lock the
vehicle. The vehicle is not locked until Dis-
tronic Plus is deactivated.
i If the ignition has been switched off, the
engine cannot be started again until Dis-
tronic Plus has been deactivated.
If Distronic Plus is activated and a fault occurs
in the system or there is a disruption in the
power supply while the vehicle is stationary,
the Brake immediately message is shown
in the multi-function display. Immediately
depress the brake firmly until the warning
message in the multi-function display goes
out or move the selector lever to P. Distronic
Plus is deactivated.
Vehicles with automatic transmission

When the vehicle is stationary and Distronic
Plus is switched on, Pis automatically selec-
ted if:
R the driver's door is opened and you release
the seat belt.
R the engine is switched off, unless it is auto-
matically switched off by the ECO Start/
Stop function.
R the bonnet is opened.
R a system fault occurs.
R the power supply is not sufficient. Setting a speed X
Press the cruise control lever to the pres-
sure point, up :for a higher speed or
down Afor a lower speed.
X Keep the cruise control lever pressed until
the desired speed is reached.
X Release the cruise control lever.
The new speed is stored. Distronic Plus is
activated and adjusts the vehicle's speed
to the new speed stored.
Making adjustments in 1 km/h incre-
ments X
Briefly press the cruise control lever to the
pressure point, up :for a higher speed or
down Afor a lower speed.
The last speed stored is increased or
reduced.

the last stored speed G
Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for the
current situation. Otherwise, sudden acceler-
ation or braking could endanger you or others.
X Briefly pull the cruise control lever towards
you ?.
X Remove your foot from the accelerator
pedal.
Distronic Plus is activated. The first time it

are met.
X Depress the brake. Vehicles with automatic transmission* with a
selector lever (example)
X
With increased force depress the brake
pedal further until HOLD:appears in the
multi-function display.
The HOLD function is activated. You can
release the brake pedal.
i If depressing the brake pedal the first
time does not activate the HOLD function,
wait briefly and then try again. G
Risk of accident
The vehicle's brakes are applied when the
HOLD function is activated. For this reason,
deactivate the HOLD function if the vehicle is
to be set in motion by other means (e.g. in a
car wash or by towing).
Deactivating the HOLD function The HOLD function is deactivated automati-
cally if:
R
you accelerate. On vehicles with automatic
transmission*, this occurs only if Dor Ris
selected.
R on vehicles with automatic transmission*,
you move the selector lever to P.
R you activate Distronic Plus*.
R you release the brakes and apply them
again with a certain amount of pressure

G
Risk of injury
Very hot or very cold air can flow from the air
vents. This could cause burns or frostbite to
bare skin in the immediate vicinity of the air
vents. Keep bare skin away from these air
vents. If necessary, direct the airflow to a dif-
ferent area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves.
R never cover the vents or air inlet and outlet
grilles in the vehicle interior.
i For virtually draught-free ventilation,
adjust the sliders of the air vents to the
centre position.

with the climatic specifications of standard
EN 590 can help to prevent operating prob-
lems. If the ambient temperature is unusually
low or if you use fuel that has not been adap-
ted to the climatic specifications (e.g. diesel
fuel from the Mediterranean area), the flow
properties of the fuel may be inadequate.
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 fuel.
Correct dosage and thorough mixing are deci-
sive factors in ensuring improvement in low-
temperature resistance. Under certain cir-
cumstances, an excessive dosage may
actually decrease low-temperature resist-
ance and should therefore be avoided (follow
the manufacturer's dosing instructions).
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Otherwise, malfunctions
can 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. Engine compartment
Bonnet
G
Risk of accident
Do not pull the release lever while the vehicle
is in motion. The bonnet may otherwise open
and block your view.
Active bonnet (pedestrian protection) The active bonnet can reduce the risk of injury
to pedestrians in certain accident situations.
Raising the bonnet increases the clearance to hard components, such as the engine. Fur-
ther information about the active bonnet
(Y
page 302).
Opening G
Risk of injury
There is a risk of injury if the bonnet is open,
even if the engine is not running.
Some engine components can become very
hot.
To avoid the risk of burns, only touch those
components described in the Operating
Instructions and observe the relevant safety
notes. G
Risk of injury
The radiator fan between the radiator and the
engine can start automatically, even if the key
has been removed from the ignition lock.
Keep away from the area of rotation of the fan
blades. Otherwise you could be injured.
Vehicles with a petrol engine:
The electronic ignition system uses high volt-
age. For this reason, you must never touch the
ignition system components (ignition coil,
ignition cable, spark plug connector or test
socket) while:
R the engine is running
R the engine is being started
R the ignition is switched on and the engine
is being cranked by hand
You could otherwise receive an electric shock
and be severely or fatally injured.
Vehicles with a diesel engine:
the electronic injector control operates at
high voltage. For this reason, you must never
touch injection system components while:
R the engine is running
R the engine is being started
R the ignition is switched on
You could otherwise receive an electric shock
and be severely or fatally injured. Engine compartment

X
Make sure that the windscreen wipers are
switched off. G
Risk of injury
The windscreen wipers and wiper linkage
could be set in motion.
When the bonnet is open, you or others could
be injured by the wiper linkage.
Make sure that the windscreen wiper is
switched off. Remove the key or make sure
that no ignition level has been selected on
KEYLESS GO*. In the instrument cluster, all of
the indicator lamps must be out.
The bonnet release lever is located in the
driver's footwell. X
Pull bonnet release lever :.
The bonnet is released.
! Make sure that the windscreen wipers
are not folded out from the windscreen.
You could otherwise damage the wind-
screen wipers or the bonnet.
The handle for opening the bonnet is located
above the radiator grille. X
Reach into the gap, pull bonnet catch han-
dle ;up and lift the bonnet.
Closing G
Risk of injury
Make sure that nobody can become trapped
as you close the bonnet.
X Lower the bonnet and let it fall from a
height of approximately 20 cm.
X Check that the bonnet has engaged prop-
erly.
i If the bonnet can be raised slightly, it is
not properly engaged. Open it again and
close it with a little more force. Engine oil
Depending on driving style, the vehicle con-
sumes up to 0.8 l oil 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.
Checking the engine oil level Before checking the engine oil level the fol-
lowing conditions for the vehicle should be
met:
R the vehicle should be parked on level
ground.
R the engine should be switched off for at
least five minutes if the engine is at normal
operating temperature.
R the engine should be switched off for at
least 30 minutes if the engine is not at
operating temperature (i.e. if you only start
the engine briefly).
Depending on the engine, the oil dipstick may
be installed at a different location. 220
