ynotes
For reasons of safety, Mercedes-Ben zrecom-
mends that you driv ewith the lights switched
on even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirement sand self-imposed obli-
gations. In these countries, the daytime driv-
ing lights are automatically switche donwhen
the engin eisstarted. Notes on driving abroad
Converting to symmetrical dipped beam
when drivin gabroad: switch the headlamps
to symmetrical dipped beam in countries in
which traffic drives on the opposite side of the
road to the countr ywhere the vehicle is reg-
istered. This prevents oncomi ngtraffic from
being dazzled .Symmetrical lights do not illu-
minate as large an area of the edg eofthe
carriageway.
Convert the headlamps as close to the border
as possible before drivin ginthese countries
(Y page 206).
Converting to asymmetrica ldipped beam
after retu rning: conver tthe headlamps back
to asymmetrical dipped beam as soon as pos-
sible after crossing the border when returning
(Y page 206).
Vehicle swith Intelligent Light System: if
the headlamps are converted to symmetrical
dipped beam, not all light functions are avail- able. "Motorway mode" and the "extended
range foglamps" are deactivated. Light switch

Risk of accident
Th ev ehicle is braked when th eHOLDfunction
or DISTRONI CPLUSisa ctivated. Therefore,
dea ctivate th eHOLD function and DISTRONIC
PLU Sbefor ethe vehicle is washed in an auto-
matic car wash.
You can wash the vehicle in an automatic car
wash from the ver ystart.
! We recommend automatic car washes
with an adjustable 40
high-pressure pre-
cleaning program. In car washes that use
hig hw ater pressures, there is adanger that
as mall quantity of water may leak int othe
vehicle.
! Cabriolet: do not treat the vehicle with
hot wax under any circumstan ces.
! Cabriolet: pull the key out of the ignition
lock when washing the vehicle .This
ensures that the win ddeflector on the
windscreen is retracted. The wind deflector
may otherwise be damaged.
If the vehicle is ver ydirty, pre-wash it before
cleaning it in an automatic car wash.
! In car washes with atowing mechanism,
make sure that the automatic transmission
is in transmission position N,otherwis ethe
vehicle could be damaged.
! Make sur ethat the side windows ar ecom-
pletel yclosed, that the ventilation/heater
blowe risfully turned off and that the wind-
screen wiper switch is set to 0.Otherwi se,
the rain/light senso rmay be activated, trig-
gering unintended wiper movemen ts.T his
could cau se damage to the vehicle.
After using an automatic car wash, wip eoff
wax from th ewindscreen and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
screen. High-pressur
ecleaners G
Risk of accident
Do not use high-pressur ecleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.
! Always maintain adistance of at least
30 cm between the vehicle and the high-
pressure cleaner nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door joint
R soft top (Cabriolet)
R wind deflector net (Cabriolet)
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
R ventilation slots
Damaged seals or electrical components
can lead to leaks or failures.
Cleanin gthe whee ls !
Do not use acidic whee lcleaning products
to remov ebrake dust .This could damage
wheel bolts and brake componen ts.
! Do not park up the vehicle for an extended
perio dstraight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosio nofthe brake discs and
brake pads/linings. For this reason, you
should drive for afew minutes after clean-
ing. Brakin gheats the brak ediscs and

to as pecial collectio npoint for old batteries. G
Risk of inju
ry
Fo rs afety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. Thes ebatteries provide
increased impact protection to prevent vehi-
cle occupant sfrom suffering aci dburns
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 abattery.
Otherwise ,you coul dcause ashort circuit
and the battery's gas mixtur ecould ignite.
R mak esure that you do not create an elec-
trostatic charge, e.g. by wearing synthetic
clothing or as aresult of friction on fabrics.
Therefore, you should not pull or slide the
batter yover carpets or other synthetic
materials.
R neve rtouch the battery first. To discharge
ap ossible electrostatic charge, step out of
the vehicle first and touc hthe bodywork.
R do not wipe the battery usin gacloth. The
battery may explode as aresult of electro-
static charge or due to flying sparks.
! Switc hoff th eengine and remove the key
before disconnectin gthe termi nalclamps
from the battery .Onvehicles with KEY-
LE SS -GO, make sure that the ignition is
switched off. Check that all the indicator
lamps in the instrument cluste rare off.
Otherwise, yo umay destroy electronic
components, 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
carr yout work on batteries yourself, e.g.
removing, charging or replacing. Always have this work performed at
aqualified specialist
workshop, e.g. aMercedes-Ben zService
Cent re. Installation location of the battery

X Turn the key to position 0(Ypage 135) in
the ignition lock and remove it, or, with
KEYLESS-GO, make sure that the ignition

missible gross vehicle weigh tofyour vehicle. G
Risk of accident
The vehicle is braked when the HOL Dfunction
or DISTRONIC PLUS is activated. Therefore,
deactivate HOLD and DISTRONIC PLUS if the
vehicle is to be towed.
It is better to have the vehicle transported
than to have it towed.
! Whe ntowing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles coul dbedamaged.
! Do not use the towing eye for recovery,
as this could damage the vehicle. If in
doubt, recover the vehicle with acrane.
! Youm ay tow the vehicle for amaximum
of 50 km. Atowing speed of 50 km /h must
no tbee xceeded.
For towing distances over 50 km, the entire
vehicl emust be lifted up and transported.
! On vehicles with KEYLESS-GO, use the
key instead of the Start/Stop button .Turn
the key to position 2in the ignition lock and
shif tthe automatic transmission to N.
Then, turn the key back to 0and leave it in
the ignitio nlock.
! Only secur ethe tow cable or towing bar
to the towing eyes. You could otherwise
damage the vehicle.
Please note:
R vehicles with an automatic transmission
must not be tow-started.
R if you ar etowing the vehicle over alonger
distance, this must be done with the rear
axle raised.
R the ignition must be switched off if you are
towin gthe vehicle with the rea raxle raised. Intervention by ESP
®
could otherwis edam-
age the brake system.
R if the vehicle has suffered transmission
damage, only tow it with the propelle rshaft
disconnected.
R if the engin edoes not start, tr yjump-start-
ing it (Y page 289).
R if it is not possible to jump-start the vehicle,
have it towed to the nearest qualified spe-
cialist workshop, e.g. aMercedes-Benz
Servic eCentre.
R the automatic transmission must be in
position Nwhen the vehicle is being towed.
Before towing the vehicle, mak esure that the
battery is connected and charged. You will

or shift the transmissio ntoNin vehicles with
an automatic transmission.
i Switch off the automatic locking feature
before the vehicle is towed (Y page 208).
You could otherwise be locked out when
pushing or towing the vehicle. Fitting the towing eye
Vehicles with atrailer to whitch: if you intend
to use the vehicle for towing, fold out the ball
coupling and connect the towbar to it
(Y page 186).
