of over 6mph (10km/h) again after a full
brake application.
i The hazard warning lamps still operate if
the ignition is switched off. Headlamp cleaning system
The headlamps are cleaned automatically if
the "Wipe with washer fluid" function is
operated five times (Y page 134) while the
lights are on and the engine is running. When
you switch off the ignition, the automatic
headlamp cleaning system is reset and
counting is resumed from 0. Cornering light function
The cornering light function improves the
illumination of the road over a wide angle in
the direction you are turning, enabling better
visibility in tight bends, for example. The

X Switch on the ignition.
X Turn the combination switch to the
corresponding position.
In the 0007or0008 position, the appropriate
wiping frequency is set automatically
according to the intensity of the rain. In
the 0008 position, the rain sensor is more
sensitive than in the 0007position, causing
the windshield wipers to wipe more
frequently.
If the wiper blades are worn, the windshield
will no longer be wiped properly. This could
prevent you from observing the traffic
conditions, thereby causing an accident.
Replace the wiper blades twice a year, ideally
in spring and fall.
i The vehicle is equipped with the MAGIC
VISION CONTROL wipe/wash system. The
washer fluid is fed through the wiper blades
and when wiping the screen with washer
fluid 0005, the water is emitted directly
from the blades. Replacing the wiper blades
Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could
be trapped by the wiper arm. There is a risk
of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper. !
Never open the hood if a windshield wiper
arm has been folded away from the
windshield.
Never fold a windshield wiper arm without
a wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.
Mercedes-Benzr ecommends that you have
the wiper blades changed at aqualified
specialist workshop.
! Always position the windshield wiper
arms vertically before folding them away
from the windshield. By doing so, you will
avoid damage to the hood.

i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may

described. This also applies to safety-
related systems and functions.

WARNING
Observe the settings recommended on the
following pages. The windows could
otherwise fog up. This could preven tyou from
observing the traffic conditions, thereby
causing an accident. G
WARNING
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. Aclogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at a qualified specialist workshop.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally when the side windows and the roof
are closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 149). i
When the weather is warm, ventilate the
vehicle for a brief period. This will speed up
the cooling process and the desired vehicle
interior temperature will be reached more
quickly.
i It is possible that the dehumidification
function of the climat econtrol system may
be activated automatically an hour after the
SmartKey has been removed. The vehicle
is then ventilated for 30 minutes to dry the
air-conditioning system. 140

WARNING
If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. This may prevent you from
observing the traffic conditions, thereby
causing an accident.
The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a
malfunction.
i The refrigerant that is used by the cooling
with air dehumidification does not contain
chlorofluorocarbons and therefore does
not damage the ozone layer. Operating the climate control systems

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 grille on the hood and in
the engine compartment on the front-
passenger side free of blockages, such as
ice, snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior.

i Read the information on qualified
specialist workshops: (Y page 38).Notes on breaking-in
anew vehicle Important safety notes
New and replaced brake pads and discs only
reach their optimum braking effect after
several hundred kilometers of driving.
Compensate for this by applying greater force
to the brake pedal. The first 1,000miles (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 You should therefore drive at varying
vehicle and engine speeds for the first
1,000miles (1,500km).
R Avoid heavy loads, e.g .driving at full
throttle, during this period.
R Change gearing ood time, before the
tachometer needle is 0001of the way to the
red area of the tachometer.
R Do not manually shift to a lower gear to
brake the vehicle.
R If possible, do not depress the accelerator
pedal past the point of resistance
(kickdown). R
Only select shift ranges 3,2or 1when
driving slowly, e.g. in mountainous terrain.
R Ideally, drive for the first 1,000 miles
(1,500km) in drive program C.
After 1,000 miles (1,500km), you can
increase the engine speed gradually and bring
the vehicle up to full speed.
Additional breaking-in notes for AMG
vehicles:
R Do not drive faster than 85 mph
(140 km/h) for the first 1,000 miles
(1,500 km).
R Only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R Change gear in good time.
i You should also observe these notes on
breaking in if the engine or parts of the drive
train on your vehicle have been replaced. AMG vehicles with self-locking rear
axle differential
Your vehicle is equipped with aself-locking
differential on the rear axle. To protect the
differential on the rear axle, carry out an oil
change after a breaking-in phase of
2,000 miles (3,000 km). This oil change
prolongs the service life of the differential.
Have the oil change carried out at a qualified
specialist workshop. Mercedes-Benz
recommends that you use an authorized
Mercedes-BenzC enter for this purpose. Driving

WARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct adepressed pedal.
The operating and road safety of the vehicle
is jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are

WARNING
Unsuitable footwear can hinder correct usage
of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
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 a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift the automatic transmission to
the desired drive position when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. You could otherwise damage the
drive train.
! AMG vehicles: at low engine oil
temperatures below 68 ‡(+20 †), the maximu
mengine speed is restricted in
order to protect the engine .To protec tthe
