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 359).
= 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 361).
= 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 317).
= All vehicles: change the wheel (  page 389). 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. 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 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

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. TIREFIT kit storage location

outside temperatures down to -20 °C. &
WARNING Risk of accident when using
tyr
e sealant
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
wit
h the tyre sealant: 
Rinse oM t
he tyre sealant from your skin
using water immediately. 
If tyre sealant gets into your eyes, thor-
oughl

y rinse them using clean water
immediately. 
If tyre sealant has been swallowed, thor-
oughl
y rinse out your mouth immediately
and drink plenty of water. Do not induce
vomiting and seek medical attention
immediately. 
Change out of clothing which has come
int

o contact with tyre sealant immedi-
ately. 
If an allergic reaction occurs, seek medi-
cal att

ention immediately. *
NOTE Ov

Let the tyre inOation com pressor run for a
maximum of ten minutes.
The tyre should then have attained a tyre pres-
sure of at least 200 kPa (2.0 bar/29 psi).
If tyre sealant leaks out, make sure you clean the
aMect
ed area as quickly as possible. It is prefera-
ble to use clean water.
If you get tyre sealant on your clothing, have it
cleaned as soon as possible with perchloroethy-
lene.
If, aser ten minutes, a tyre pressure of 200 kPa
(2.0 bar/29 psi) has not been attained: 
Switch oM t
he tyre inOation compressor. 
Unscrew the Nlling hose fr
om the valve of the
defective tyre.
Please note that tyre sealant may leak out when
unscr
ewing the Nlling hose. 
Drive forwards or in reverse very slowly for
appr
oximately 10 m. 
Pump up the tyre again.
Aser a maximum of t

en minutes the tyre pres-
sure must be at least 200 kPa (2.0 bar/
29 psi). &
WARNING Risk of accident due t
o the
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
tyre in this instance.
The braking and driving characteristics may be
greatly impaired. 
Do not continue driving. 
Consult a q
ualiNed specialist workshop. If, aser
t
en minutes, a tyre pressure of 200 kPa
(2.0 bar/29 psi) has been attained: 
Switch oM t

Unscrew the Nlling hose fr
om the valve of the
defective tyre. &
WARNING Risk of accident fr
om driving
with sealed tyres
A tyre temporarily sealed with tyre sealant
im
pairs the handling characteristics and is not
suitable for higher speeds. 
Adapt your driving style accordingly and
dr

ive carefully. 
Do not exceed the maximum speed limit
wit
h a tyre that has been repaired using
tyre sealant. 
Observe the maximum permissible speed of
80 km/h

for a tyre sealed with tyre sealant.

If there is a short circuit or sparks are created,
t
here is a danger of hydrogen gas igniting
when you charge the battery. 
Make sure that the POSITIVE terminal of
a connect

identical polarity. 
During starting assistance, observe the
seq
uence described for connecting and
disconnecting the jump leads. 
Do not connect or disconnect the bat-

ery terminals with the engine running. &
WARNING Risk of e
xplosion due to explo-

An explosive mixture of gases can escape
fr
om the battery during charging and starting
assistance. 
Fire, naked Oames, smoking and cr

Make sure there is adequate ventilation. 
Do not stand over the battery. &
WARNING Risk of e
xplosion from a frozen
battery
A discharged battery may freeze at tempera-
tur
es slightly above or below freezing point.
During starting assistance or battery charging,
battery gas can be released. 
Always allow a battery to thaw before
c
harging it or performing starting assis-
tance. If the indicator/warning lamps in the instrument
clus
ter do not light up at low temperatures, it is
very likely that the discharged battery has frozen.
In this case you may neither jump-start the vehi-
cle nor charge the battery.
The service life of a battery that has been thawed
may be dramatically shortened. The starting char-
acteristics may be impaired, especially at low
temperatures.
It is recommended that you have a thawed battery
checked at a qualiNed specialist workshop. Plug-in hybrid
