MOExtended tyres (tyres with run-flat
characteristics) G
WARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is arisk of accident.
Do not exceed the stated maximu mspeed.
Avoid abrupt steering and driving manoeu-
vres, and driving over obstacles (kerbs ,pot-
holes, off-road). This applies in particular to a
laden vehicle.
Stop driving in emergency mode if:
R you hear banging noises.
R the vehicle start stoshake.
R you see smok eand smell rubber.
R ESP ®
is intervening constantly.
R ther eare tears in the sidewalls of the tyre.
After driving in emergency mode, have the
wheel rims checked at aqualified specialist
workshop with regard to their further use. The
faulty tyre must be replaced.
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if ther eisatotal loss of
pressure in one or more tyres.
MOExtended tyres may only be used in con-
junction with an activ etyre pressure loss
warning system or with an activ etyre pres-
sure monitor.
The maximum driving distance is approx-
imately 80 km when the vehicle is partially
laden, and approximately 30 km when the
vehicle is fully laden.
In addition to the vehicle load, the driving dis-
tanc epossible depends upon:
R speed
R road condition
R outside temperature
The driving distanc epossible in run-flat mode
may be reduced by extreme driving condi-
tions/manoeuvres, or it can be increased
through amoderat estyle of driving. The maximum permissible distanc
ewhich
can be driven in run-flat mode is counted from
the momen tthe tyre pressure loss warning
appears in the multifunction display.
You must not exceed amaximum speed of
80 km/h.
i When replacing one or all tyres, make
sure that you only use tyres marked
"MOExtended". Make sure that you only
use the size of tyre specified for the vehicle. TIREFIT kit
Using the TIREFIT kit TIREFIT is
atyre sealant.
You can use TIREFIT to seal punctures of up
to 4m m, particularly those in the tyre tread.
You can use TIREFIT at outside 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. Flat tyre

Tyre pressure monitor
Important safety notes It is the driver's responsibility to set the tyre
pressure to the recommende dcold tyre pres-
sure suitable for the operating situation
(Y page 331). Note that the correc ttyre pres-
sur efor the curren toperating situation must
first be taught-in to the tyre pressure monitor.
If there is asubstantial loss of pressure, the
warning threshold for the warning message is
aligned to the referencev alues taught-in.
Restart the tyre pressure monitor after
adjusting to the cold tyre pressure
(Y page 335). The current pressures are
saved as new referencev alues. This will
ensure that awarning message will only
appearift he tyre pressure drops significantly.
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. Observe
the notes on the recommended tyre pressure
(Y page 331).
The tyre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign object.Int he
event of asudden loss of pressure, bring the
vehicle to ahalt by braking carefully. Avoid
abrupt steering manoeuvres.
If at yre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you if the
pressure drops in one or more of the tyres.
The tyre pressure monitor only functions if
the corresponding sensors are fitted to all
wheels.
Information on tyre pressures is displayed in
the multifunction display. After afew minutes
of driving, the current tyre pressure of each
tyre is shown in the multifunction display.
The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at afilling station using apressure
gauge. The tyre pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tyre pressure values indicated by
apressure gauge are
higher than those shown by the on-board
computer. In this case, do not reduce the tyre
pressures.
The operation of the tyre pressure monitor
can be affected by interference from radio
transmitting equipment (e.g. radio head-
phones, two-way radios) that may be being
operated in or near the vehicle.
Checking tyrep ressureelectronically X
Make sure that the key is in position

X Press the abutton.
The current tyre pressure for each wheel
will be displayed in the multifunction dis-
play.
If the vehicle was parked for longer than
20 minutes the Tyre pressures will be displayed after
afew minutes of driving message is shown.
After ateach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. If aclear allocation of
the tyre pressure values to the individual
wheels is not possible, the Tyre pressure monitor active message is shown instead
of the tyre pressure display. The tyre pres-
sures are already being monitored.
i If an emergency spare wheel is fitted, the
system may continue to show the tyre pres-
sure of the wheel that has been removed
for afew minutes. If this occurs, note that
the value displayed for the position where
the spare wheel is fitted is not the same as
the current tyre pressure of the emergency
spare wheel. 334

are displayed for th ecorrec tpositions.
Restarting th etyrep ressure monitor When you restar
tthe tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the refer-
ence values for monitoring. In most cases, the
tyre pressure monitor will automatically
detect the new referencev alues after you
have changed th etyrep ressure .However,
you can also define reference values man-
uallyasd escribed here. The tyre pressure
monitor then monitors the new tyre pressure
values.
X Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions.
Also observe the notes in the section on
tyre pressures (Y page 331).
