Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and
brake pads, thus drying them. The vehicle
can then be parked up. Care of the exterior
Automatic car wash G
Risk of accident
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, following a car wash, drive with
particular care until the brakes are dry. G
Risk of accident
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate the HOLD function and DISTRONIC
PLUS before the vehicle is washed in an auto-
matic car wash.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! In car washes with a towing mechanism,
make sure that the automatic transmission
is in transmission position N, otherwise the
vehicle could be damaged.
R Vehicles with a key:
do not remove the key from the ignition
lock. Do not open the driver's door or front-passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position
P
automatically and locks the wheels. You
can prevent this by shifting the auto-
matic transmission to Nbeforehand.
R Vehicles with KEYLESS-GO:
do not open the driver's door or front-
passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position P
automatically and locks the wheels.
Observe the following to make sure that the
automatic transmission stays in position N:
X Make sure the vehicle is stationary and the
ignition is switched off.
X Turn the key to position 2(Y page 129) in
the ignition lock.
Use the key instead of the Start/Stop but-
ton on vehicles with KEYLESS-GO.
X Depress and hold the brake pedal.
X Shift the automatic transmission to posi-
tion N.
X Release the brake pedal.
X Release the parking brake.
X Switch off the ignition and leave the key in
the ignition lock.
! Make sure that:
R the side windows and sliding sunroof are
closed completely.
R the blower for the ventilation/heating is
switched off (OFF button is depressed).
R the windscreen wiper switch is at posi-
tion 0.
The vehicle could otherwise be damaged.
After using an automatic car wash, wipe off
wax from the windscreen and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
screen. Care

Cleaning the sensors
X
Clean sensors :of the driving systems
with water, car shampoo and a sof tcloth.
! If you clean the sensors with a high-pres-
sure cleaner, make sure that you keep a
distance of at least 30 cm between the
vehicle and the high-pressure cleaner noz-
zle. Information about the correct distance
is available fro mthe equipment manufac-
turer.
Cleaning the reversing camera X
Use clear water and a soft cloth to clean
camera lens :.
! Do not clean the camera lens and the area
around the reversing camera with a high-
pressure cleaner. Cleaning the exhaust tail pipes Impurities combined with the effects of road
grit and corrosive environmental factors may
cause flash rust to form on the surface. You
can restore the original shine of the exhaust
tail pipe by cleaning it regularly, especially in
winter and after washing.
!
Do not clean the exhaust tail pipes with
alkaline-based cleaning agents, such as
wheel cleaner.
X Cleant he exhaust tail pipes with a chrome

can be obtained from a Mercedes-Benz
Service Centre. Battery
Important safety notes
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period.
To preven tdamage from corrosion, only
replace the battery with one that has a central
ventilation cover.
Only replace a battery with a battery that has
been recommended by Mercedes-Benz. Consult a Mercedes-Ben
zService Centre if
you wish to leave your vehicle parked up for
a long period of time. G
Risk of injury

tective measures when handling batteries. Risk of explosion
Fire, naked flames and
smoking are prohibited
when handling the battery.
Avoid creating sparks.
Battery acid is caustic.
Avoid contact with the skin,
eyes or clothing.
Wear suitable protective
clothing, in particular
gloves, an apron and a face
mask.

BatteryBreakdown assistance

recycled in an environmen-
tally responsible manner.
Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to a qualified spe-
cialist workshop, e.g. a
Mercedes-Benz Service
Centre, or to a special col-
lection point for old batter-
ies.
G
Risk of injury
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for yourv ehicle by
Mercedes-Benz .These batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering acid burns
should the battery be damaged in the event
of an accident.
To prevent acid burns, observe the following
safety notes when handling batteries:
R do not lean over the battery.
R do not place any metal objects on a battery.
Otherwise, you could cause a short circuit
and the battery's gas mixture could ignite.
R make sure that you do not create an elec-
trostatic charge, e.g. by wearing synthetic
clothing or as a result of friction on fabrics.
Therefore, you should not pull or slide the
battery over carpets or other synthetic
materials.
R never touch the battery first. To discharge
a possible electrostatic charge, step out of
the vehicle first and touch the bodywork.
R do not wipe the battery using a cloth. The
battery may explode as a result of electro-
static charge or due to flying sparks.
! Switch off the engine and remove the key
before disconnecting the terminal clamps
from the battery. On vehicles with KEY-
LESS-GO, make sure that the ignition is
switched off. Check that all the indicator
lamps in the instrumentc luster are off.You may otherwise destroy electronic compo-
nents, such as the alternator.
i Remove the key if you park the vehicle
and do not require any electrical consum-
ers. The vehicle will then use very little
energy, thus conserving battery power.
Mercedes-Benz recommends that you do not
carry out work on batteries yourself, e.g.
removing, charging or replacing. Always have
this work performed at aqualified specialist
workshop, e.g. a Mercedes-Ben zService
Centre. Installation location of the battery

Tyre tread
G
Ris
kofa ccident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3mm.
Thus, you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4mmorless as they no lon-
ger provide adequate grip.
R the tread on a tyre may not wear evenly.
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tyres. If necessary,
turn the fron twheels to full lock in order to
inspect the tyre tread more easily.
Otherwise, you could lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. Notes on selecting, fitting and replac-
ing tyres
R Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fittingn ew tyres, run them in at mod-
erate speeds for the first 100 km, as they
only reach their full performance after this
distance.
R Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the emergency spare wheel/spare wheel. MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics) allow you to continue driving the vehicle even when one or more tyres lose all
air pressure.
MOExtended tyres may only be used in con-
junction with the activated tyre pressure loss
warning system or with the activated tyre
pressure monitor and on wheels specifically
tested by Mercedes-Benz.
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with the TIREFIT
kit if you fit tyres that do not feature run-
flat properties, e.g. winter tyres. You can
obtain a TIREFIT kit from a Mercedes-Benz
Service Centre, for example.
You will find notes on driving with a flat tyre
in the "Breakdown assistance" section
(Y page 289). Winter operation
Please bear the following in mind
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Benz
Service Centre, at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 309). Driving with summer tyres
At temperatures below +7 †, summer tyres
lose elasticity and therefore traction and
braking power –change the tyres on your
vehicle to M+S tyres. Using summer tyres at
very cold temperatures could cause tears to
form, thereby damaging them permanently.
Mercedes-Ben zcannot accept responsibility
for this type of damage. M+S tyres
At temperatures below +7 †, use winter tyres
or all-season tyres. Both types of tyre are
identified by the M+S marking. Winter operation
303Wheels and tyres Z

Only winter tyres bearing the
isnowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintry road con-
ditions. Only these tyres will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter, as these tyres
have been designed specificallyf or driving on
snow.
Use M+S tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
M+S tyres with a tread depth of less than
4mmm ust be replaced. They are no longer
suitable for winter use and can no longer pro-
vide sufficient grip .This could cause you to
lose control of your vehicle and cause an acci-
dent.
Always observe the maximum permissible
speed specified for the M+S tyres you have
fitted.
If you fit M+S tyres which have a lower max-
imum permissible speed than that of the vehi-
cle, affix an appropriate warning sign in the
driver's field of vision. This can be obtained
at a qualified specialist workshop, e.g. from a
Mercedes-Benz Service Centre.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres(Y page 164).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 305).
X Restart the tyre pressure monitor
(Y page 308). G
Risk of accident
If you fit the spare wheel when driving with M
+S tyres, bear in mind that driving stability will
be impaired due to unstable cornering char-
acteristics caused by the different tyres. You
should therefore adapt your driving style and
drive carefully. Have the spare wheel replaced at the nearest
qualified specialist workshop which has the
necessary specialist knowledge and tools to
carry out the work required. Mercedes-Benz
recommends that you use aMercedes-Benz
Service Centre for this purpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at a qualified
specialist workshop. Snow chains
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle
by Mercedes-Benz, or that are of a corre-
sponding standard of quality.
If you intend to fit snow chains, please bear
the following points in mind:
R you may not attach snow chains to all
wheel-tyre combinations; see the informa-
tion under "Wheels and tyres" in the "Tech-
nical data" section.
R snow chains must not be fitted to emer-
gency spare wheels, e.g. a "Minispare" or
collapsible emergency spare wheel.
R only fit snow chains in pairs and to the rear
wheels, even on vehicles with 4MATIC.
Observe the manufacturer's installation
instructions.
! Vehicles with steel wheels
If you wish to fit snow chains to steel
wheels, make sure that you remove the
respective wheels' hubcaps first .The hub-
caps may otherwise be damaged.
On vehicles with AIRMATIC, you must drive at
raised vehicle level if snow chains have been
fitted (Y page 167).
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate
ESP ®
(Y page 58) when pulling away with
snow chains fitted. This way you can allow
the wheels to spin in a controlled manner, 304
