is intervening constantly.
R there are tears in the sidewall softhe tyre.
After driving in emergency mode, have the
whee lrims checked at aquali fied specialist
workshop with regar dtotheir furthe ruse. The
fault ytyre must be replaced.
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is atotal loss of
pressure in one or mor etyres.
MOExtended tyres may only be used in con-
junction with an active tyre pressure loss
warning syste morwith an activ etyre pres-
sure monitor.
The maximum driving distance is approx-
imately 80 km when the vehicle is partially
laden, and approximatel y30kmwhen the
vehicle is fully laden.
In addition to the vehicle load, the drivin gdis-
tance possible depends upon:
R speed
R road condition
R outside temperature
The drivin gdistance possible in run-flat mode
may be reduced by extrem edriving condi-
tions/manoeuvres ,oritcan be increased
through amoderate style of driving.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyr epressure loss warning
appe arsint he multifunction display.
You must not exceed amaximum spee dof
80 km/h.
i When replacing one or all tyres, make
sure tha tyou only use tyres marked
"MOExtended". Make sure that you only
use the size of tyr especified for the vehicle.
i Vehicles with MOExtended tyres are not
equipped with aTIREFIT kit at th efactory.
It is therefore recommended that you addi-
tionally equip your vehicle with aTIREFIT kit
if yo ufit tyres that do not featur erun-flat
characteristics, e.g. winter tyres. ATIREFIT kit can be obtaine
dfrom aqualified spe-
cialist workshop. TIREFIT kit
Usin gthe TIREFIT kit TIREFIT is
atyre seal ant.
You can use TIREFIT to seal punctures of up
to 4m m, particularl ythose in the tyr etread.
Yo uc an use TIREFI Tatoutside temperatures
down to Ò20 †. G
WARNING
In the following situations, the tyre sealant is
unable to provide sufficient breakdown assis-
tance, as it is unable to seal the tyre properly:
R there are cuts or punctures in the tyre
larger than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tyre pressures
or on aflat tyre.
There is arisk of accident.
Do not drive any further. Contact aqualified
specialist workshop. G
WARNING
The tyre sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not
inhale TIREFIT fumes. Keep tyre sealant away
from children. There is arisk of injury.
If you come into contact with the tyre sealant,
observe the following:
R Rinse off the tyre sealant from your skin
immediately with water.
R If the tyre sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
R If tyre sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately. Flat tyre

re pr essur eloss warning system
Important safety notes While the vehicle is in motion, the tyre pres-
sure loss warnin gsystem monitors the set
tyre pressure using the rotational speed of
the wheels. This enable sthe system to detect
significant pressur eloss in atyre. If the speed
of rotation of awheel changes as aresult of
al oss of pressure, acorrespondin gwarning
message will appea rinthe multifunction dis-
play.
The tyr epressure warning system does not
warn yo uofani ncorrectly set tyre pressure.
Observe the notes on the recommended tyre
pressure (Y page399).
Th et yre pressure los swarning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign objec t. Inthe
event of asudden loss of pressure, bring the
vehicle to ahalt by braking carefully. Avoid
abrupt steering manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration). R
you are towing avery heavy or large trailer.
R you are driving with aheavy load (in the
vehicle or on the roof).

ing system Restart the tyre pressure loss warnin

X Before restarting, make sure that the tyre
pressures are set properly on all four tyres
for the respective operating conditio ns.
The recommended tyr epressures can be
found in th etable on the fuel filler flap.
The tyre pressure loss warning system can
only give reliabl ewarnings if you have set
the correct tyre pressure. If an incorrect
tyre pressure is set, these incorrec tvalues
will be monitored.

Important safet ynotes It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operatin
gsituation
(Y page 399). Note that the correct tyre pres-
sure for the curren toperatin gsituation must
first be taught-in to the tyre pressure monitor.
If ther eisas ubstantial loss of pressure, the
warning threshold for the warning messag eis
aligned to the referenc evalues taught-in.
Restart the tyre pressure monitor after
adjustin gtothe cold tyr epressure
(Y page 403). Th ecurren tpressures are
saved as new referenc evalues. This will
ensure that awarning mess agewillonly
appear if the tyre pressure drops significantly.
The tyre pressure monitor doe snot warn you
of an incorrectly set tyr epressure. Observe
th en otes on the recommended tyr epressure
(Y page 399).
Th et yre press urem onitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign object. In the
even tofas udden loss of pressure, bring the

Th et yre pressure values indicated by the on-
board computer may differ from thos emeas-
ured at afilling station using apressure

The operation of the tyr epressure monitor
can be affecte dbyinterference from radio
transmitting equipment (e.g .radio head-
phones ,two-way radios) that may be being
operated in or near the vehicle.

have changed the tyr epressure. However,
you can also define referenc evalues man-
