MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking next to the tire size designation, the load-
bearing capacity and the speed index
(
Ypage 345).
MOExtended tires may only be used in con-
junction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If a pressure loss warning message
appears in the multifunction display:
Robserve the instructions in the display mes-
sages (
Ypage 250).
Rcheck the tire for damage.
Rif driving on, observe the following notes.
The driving distance possible in run-flat mode
is approximately 50 miles (80 km) when the
vehicle is partially laden. When the vehicle is
fully laden it is approximately 19 miles
(30 km).
In addition to the vehicle load, the driving dis-
tance possible depends upon:
Rvehicle speed
Rroad condition
Routside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving condi-
tions or maneuvers, or it can be increased
through a moderate style of driving.
The driving distance possible in run-flat mode
is counted from the moment the tire pressure loss warning appears in the multifunction dis-
play.
Flat tire311
Breakdown assistance

You must not exceed a maximum speed of
50 mph (80 km/h).
When replacing one or all tires, please
observe the following specifications for your
vehicle's tires:
Rsize
Rtype and
Rthe "MOExtended" mark
If a tire has gone flat and cannot be replaced
with a MOExtended tire, a standard tire may
be used as a temporary measure. Make sure
that you use the proper size and type (sum-
mer or winter tire).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory. It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if
you mount tires that do not feature run-flat
properties, e.g. winter tires. A TIREFIT kit may
be obtained from a qualified specialist work-
shop.
Important safety notes
GWARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is a risk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, potholes,
off-road). This applies in particular to a laden
vehicle.
Stop driving in emergency mode if:
Ryou hear banging noises.
Rthe vehicle starts to shake.
Ryou see smoke and smell rubber.
RESP®is intervening constantly.
Rthere are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheel rims checked at a qualified specialist
workshop with regard to their further use. The
defective tire must be replaced in every case.
TIREFIT kit
Important safety notes
TIREFIT is a tire sealant.
You can use TIREFIT to seal punctures of up to
0.16 in (4 mm), particularly those in the tire
tread. You can use TIREFIT at outside tem-
peratures down to Ò4 ‡ (Ò20 †).
GWARNING
In the following situations, the tire sealant is
unable to provide sufficient breakdown assis-
tance, as it is unable to seal the tire properly:
Rthere are cuts or punctures in the tire larger
than those mentioned above.
Rthe wheel rim is damaged.
Ryou have driven at very low tire pressures or on a flat tire.
There is a risk of an accident.
Do not drive the vehicle. Contact a qualified
specialist workshop.
GWARNING
The tire 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 tire sealant away
from children. There is a risk of injury.
If you come into contact with the tire sealant,
observe the following:
RRinse off the tire sealant from your skin
immediately with water.
RIf the tire sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
RIf tire sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
RImmediately change out of clothing which
has come into contact with tire sealant.
RIf an allergic reaction occurs, seek medical
attention immediately.

XPress on and off switch ?on the tire infla-
tion compressor to ON.
The tire inflation compressor is switched
on. The tire is inflated.
First, tire sealant is pumped into the tire.
The pressure can briefly rise to approx-
imately 500 kPa (5 bar/73 psi).
Do not switch off the tire inflation com-
pressor during this phase.
XLet the tire inflation compressor run for a
maximum of ten minutes. The tire should
then have attained a pressure of at least
200 kPa (2.0 bar/29 psi).

If a pressure of 200 kPa (2.0 bar/29 psi) has
been attained after five minutes, see "Tire
pressure reached" (
Ypage 314).
If a tire pressure of 200 kPa (2.0 bar/29 psi)
has not been attained after five minutes, see
"Tire pressure not reached" (
Ypage 314).
If tire sealant has escaped, clean it off affec-
ted areas as quickly as possible. Use plain
water if possible.
If your clothes are soiled with tire sealant,
have them cleaned with perchloroethylene at
a dry cleaner as soon as possible.
Tire pressure not reached
If a tire pressure of 200 kPa (2.0 bar/29 psi)
has not been attained after ten minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of
the faulty tire.
Note that tire sealant may escape when you unscrew the filler hose.
XVery slowly drive forwards or reverse
approximately 30 ft (10 m).
XPump up the tire again.
After a maximum of ten minutes, the tire
pressure must be at least 200 kPa (2.0 bar/29 psi).
GWARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and a tire
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tire pressure reached
GWARNING
A tire temporarily sealed with tire sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed the specified maximum speed with a tire that
has been repaired using tire sealant.
The maximum permissible speed for a tire
sealed with tire sealant is 50 mph (80 km/h). The upper part of the TIREFIT sticker must be
affixed to the instrument cluster in the driv-
er's field of vision.
!Residue from the tire sealant may come
out of the filler hose after use. This could
cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.
HEnvironmental note
Have the used tire sealant bottle disposed of
professionally, e.g. at a qualified specialist
workshop.
If a tire pressure of 200 kPa (2.0 bar/29 psi)
has been attained after ten minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of
the faulty tire.
XStow the tire sealant bottle and the tire
inflation compressor.
XPull away immediately.
XStop after driving for approximately ten
minutes and check the tire pressure with
the tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
GWARNING
If the required tire pressure is not reached
after driving for a short period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
