WARNING Risk of entr
apment if the wind-
screen wipers are switched on while the
windscreen is being cleaned
If the windscreen wipers are set in motion
while y
ou are cleaning the windscreen or

screen or wiper blades. To avoid damage to the vehicle, observe the notes
on cleaning and car

e of the following car parts:
Wheels and rims
= Use water and acid-free alloy wheel cleaners.
= Do not use acidic alloy wheel cleaners to
remove brake dust. This could damage wheel
bolts and brake components.
= To avoid corrosion of the brake disks and
brakepads, drive the vehicle for a few minutes
aser cleaning before parking it. The brake
disks and brakepads warm up and dry out.
Windows
= Clean the windows inside and outside with a
damp cloth and with a cleaning agent recom-
mended for Mercedes-Benz.
= Do not use dry cloths or abrasive or solvent-
based cleaning agents to clean the inside of
windows.
% Aser c
hanging the wiper blades or treating
the vehicle with wax, clean the windscreen
thoroughly with cleaning agents recommen-
ded for Mercedes-Benz. Failure to observe the application instructions may result in damage,
smear mar
ks or dazzling spots.
% Remove external fogging or dirt on the wind-

ve the wiper arms into the replacement
position (  page 170).
= With the wiper arms folded out, clean the
wiper blades with a damp cloth.
% Make sure that the wiper blades are coated.
The coating can lea

ve residues on a cloth. Do
not rub the wiper blades excessively or clean
them too osen.
Exterior lighting = Clean t

he lenses with a wet sponge and mild
cleaning agent (e.g. car shampoo).

a minimum distance of 30 cm.
Running boards
= Use water and acid-free cleaning agents.
= Do not clean the aluminium trim inserts of the
running board with alkaline or acidic cleaning
agents such as wheel cleaners. Do not use
acidic alloy wheel cleaners to remove brake
dust. The aluminium trim inserts could other-
wise be damaged.
Reversing camera and 360° camera = Open the camera cover with the multimedia
system ( page 288).
= Use clean water and a sos cloth to clean the

Regular cleaning and care of the leather
reduces soiling, wear marks and ageing dam-
age and thus signiNcantly extends its life
span. Clothing that can leave stains (e.g.
jeans) can discolour the leather.

Flat tyre
Notes on Oat
tyr es&
WARNING Risk of accident due t
o a Oat
tyre
A Oat tyr
e severely aMects the driving charac-
teristics as well as the steering and braking of
the vehicle.
Tyres without run-Oat characteristics: 
Do not drive with a Oat tyr
e.
Change the Oat tyr
e immediately with an
emergency spare wheel or spare wheel.
Alternatively, consult a qualiNed special-
ist workshop.
Tyres with r
un-Oat characteristics:
Observe the information and warning
no
tes on MOExtended tyres (run-Oat
tyres). In the event of a Oat
tyr
e, the following options are
available depending on your vehicle's equipment:
= Vehicles with MOExtended tyres: it is possible
to continue the journey for a short period of
time. Make sure you observe the notes on
MOExtended tyres (run-Oat tyres)
( page 384).
= Vehicles with a TIREFIT kit: you can repair the
tyre so that it is possible to continue the jour-
ney for a short period of time. To do this, use
the TIREFIT kit ( page 386).
= Vehicles with Mercedes me connect: you can
make a call for breakdown assistance via the
overhead control panel in the case of a break-
down (  page 341).
= All vehicles: change the wheel (  page 411). Notes on MOExtended tyres

un-Oat tyres) &
WARNING Risk of accident when dr
iving in
limp-home mode
Driving in emergency mode impairs the han-
dling c
haracteristics of the vehicle. 
Do not exceed the permissible maximum
speed of t
he MOExtended tyres. 
Avoid any abrupt steering and driving
manoeuvr
es as well as driving over
obstacles (kerbs, pot holes, oM-road).
This applies, in particular, to a loaded
vehicle. 
Stop driving in the emergency mode if
y

ou notice:
= banging noise
= v

ehicle vibration
= smoke which smells like rubber
= continuous ESP n
intervention
= cracks in the tyre sidewalls 
Aser dr
iving in emergency mode, have
the rims checked by a qualiNed specialist
workshop with regard to their further
use. 
The defective tyre must be replaced in
e

very case. 384
Breakdown assistance

With MOExtended tyres
(r un-Oat tyres), you can
continue to drive your vehicle even if there is a
total loss of pressure in one or more tyres. How-
ever, the tyre aMected must not show any clearly
visible damage.
You can recognise MOExtended tyres by the
MOExtended marking which appears on the side
wall of the tyre.
Vehicles with tyre pressure monitoring system:
MOExtended tyres may only be used in conjunc-
tion with an activated tyre pressure monitoring
system.
If a pressure loss warning message appears in the
driver's display, proceed as follows:
= Check the tyre for damage.
= If driving on, observe the following notes. Driving distance possible in emergency mode

he pressure loss warning: Load condition Driving distance possi-
ble in emer
gency mode
Partially laden 80 km
Fully laden 30 km The driving distance possible in emergency mode
ma
y vary depending on the driving style. Observe
the maximum permissible speed of 80 km/h.
If a tyre has gone Oat and cannot be replaced with
an MOExtended tyre, you can use a standard tyre
as a temporary measure. Storage location of the TIREFIT kit (not plug-in

The tyre sealant may be unable to seal the
tyr
e properly, especially in the following cases:
= there are large cuts or punctures in the
tyre (larger than damage previously men-
tioned)
= the wheel rims have been damaged
= aser journeys with very low tyre pressure
or with Oat tyres 
Do not continue driving. 
Consult a q
ualiNed specialist workshop. &
WARNING Risk of injur
y and poisoning
from tyre sealant
Tyre sealant is hazardous to health and causes
ir
ritation. Do not allow it to come into contact
with your skin, eyes or clothing, and do not
swallow it. Do not inhale any vapours. Keep
the tyre sealant away from children. Observe the following if you come into contact
