Notes on care of the interior
&
WARNING Risk of injur y from plastic parts
breaking oM aser the use of solvent-based
care products
Care and cleaning products containing sol-
v
ents can cause surfaces in the cockpit to
become porous. When the airbags are
deployed, plastic parts may break away. 
Do not use any care or cleaning products
cont

aining solvents to clean the cockpit. &
WARNING Risk of injur
y or fatal injuries
from bleached seat belts
Bleaching or dyeing seat belts can severely
w
eaken them.
This can, for example, cause seat belts to tear
or fail in an accident. 
Never bleach or dye seat belts. To avoid damage to the vehicle, observe the fol-
lo
wing notes on cleaning and care: Seat belts

mended for Mercedes-Benz.
= Leather care: Use a leather care agent that
has been recommended for Mercedes-Benz.
= Do not allow the leather to become too damp.
= Do not use a microNbre cloth.
% Leather is a natural product. It exhibits natural
sur
face properties such as diMerences in
structure, marks caused by growth and injury
or subtle colour diMerences. These surface
properties are characteristics of leather and
not material faults. What's more, leather is
subject to a natural ageing process during
which the surface properties change.
Genuine leather seat covers
= V

acuum up dirt such as crumbs or dust and
then clean the seat covers with a damp cotton cloth and wipe down with a dry cloth. Regu-
lar

ly clean the seat covers.

Regular cleaning and care of the leather
reduces soiling, wear marks and ageing dam-

span. Clothing that can leave stains (e.g.
jeans) can discolour the leather. DINAMICA seat covers

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 362).
= 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 364).
= 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 320).
= All vehicles: change the wheel (  page 391). Notes on MOExtended 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. 362

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 loss warning system:
MOExtended tyres may only be used in conjunc-
tion with an activated tyre pressure loss warning
system.
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
aser t
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

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

speciNed tyre pressure not being attained
If the speciNed tyr
e pressure is not attained
aser the speciNed time, the tyre is too badly
damaged. The tyre sealant cannot repair the
