nto xenon bulbs, you also cannot
replace LED bulbs. Have LED bulbs replaced
at a qualified specialist workshop.
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.

Risk of injury
Bulbs and lights can become very hot. For this
reason, allow them to cool down before
changing them. Otherwise, you could burn
yourself when you touch them.
Keep bulbs out of the reach of children. Oth-
erwise, they could damage them, for example,
and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may explode and injure you.
Halogen bulbs are pressurised and could
explode when you change them, especially if
they are very hot. You should therefore wear
eye protection and gloves when you are
changing them.
There are bulbs other than the xenon and LED
bulbs that you cannot replace. Replace only
the bulbs listed (Y page 105). Have the bulbs
that you cannot replace yourself changed at
a qualified specialist workshop.
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. If you require assistance changing bulbs, con-
sult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when fitting.
Only use bulbs of the correc
ttype.
If the new bulb still does no tlight up, consult
a qualified specialist workshop.
Bulbs and lamps are an importan taspect of

Risk of accident
The windscreen will not longer be wiped prop-
erly if the wiper blades are worn. This could
prevent you from observing the traffic condi-
tions, thereby causing an accident .Replace
the wiper blades twice a year, ideally in spring
and autumn.
! Do not operate the windscreen wipers
when the windscreen is dry, as this could
damage the wiper blades. Moreover, dirt
that has collected on the windscreen can
scratch the glass if wiping takes place when
the windscreen is dry.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Clean the
windscreen with washer fluid after an auto-
matic car wash. Combination switch

! Intermittent wiping with rain sensor: due
to optical influences and the windscreen
becoming dirty in dry weather conditions,
the windscreen wipers may be activated
inadvertently. This could damage the wind-
screen wiper blades or scratch the wind-
screen.
For this reason, you should always switch
off the windscreen wipers in dry weather.
In the ÄorÅ position, the appropriate
wiping frequency is set automatically accord-
ing to the intensity of the rain. In the Å
position, the rain sensor is more sensitive
than in the Äposition, causing the wind-
screen wiper to wipe more frequently. Replacing the wiper blades
Important safety notes G
Risk of accident
The wiper arms could start moving and cause
an injury if you leave the windscreen wipers
switched on.
Remove the key from the ignition lock before

Risk of accident
Clear all windows of ice or snow before setting
off. Otherwise, impaired visibility could
endanger you and others.
The rear window heating has ahigh current
draw. You should therefore switch it off as
soon as the window is clear, as it only
switches off automatically after several
minutes. If the battery voltage is too low, the rear win-
dow heating may switch off.

tion mode

unpleasan todours are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.

the same for all contro lpanels. G
Ris
kofa ccident
Only switch ove rto air-recirculation mode

wise, the windows could mist up, thus impair-
ing visibility and endangering yourself and
others. This may prevent you from observing
the traffic conditions, thereby causing an
accident.

General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 183) and Lane Keeping
Assist (Y page 185).
Blind Spot Assist Important safety notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. Blind Spot Assist provides assistance
at speeds higher than 30 km/h. A warning
lamp in the exterior mirrors draws your atten-
tion to detected vehicles in the monitored
area. If you then switch on the corresponding
turn signal to change lane, you will also
receive an optical and acoustic collision warn-
ing. For this purpose, Blind Spot Assist uses
sensors in the rear bumper. G
Risk of accident
Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some vehi-
cles and is no substitute for attentive driving.
Blind Spot Assist cannot detect road and traf-
fic conditions. It may fail to detect narrow
vehicles, such as motorcycles or bicycles, or
only detect them too late.
Monitoring may be affected by dirty sensors,
strong spray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 327).
For Blind Spot Assist to assist you when driv-
ing, the radar sensor system must be
switched on (Y page 210) and operational. Driving systems

system components (ignition coil, ignition
cables, spark plug connectors 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 suffer an electric shock
and be seriously or even fatally injured.

properly engaged. Open it again and close
it with a little more force. Engine oil
Notes on the oil level Depending on driving style, the vehicle con-
sumes a maximum of 0.8 l oil per 1000 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 oil level using the oil dip-
stick
Depending on the engine, the oil dipstick may
be installed at a different location.
When checking the oil level:
R
park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature. Example: vehicles with a petrol engine
Example: vehicles with a diesel engine
X

267Maintenance and care Z

Always have paintwork repairs performed
at a qualified specialis tworkshop, e.g. a
Mercedes-Benz Service Centre.
! Do not use wash programs with a hot wax
treatment under any circumstances.
i Use only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products.
