R if the rear of your vehicle is damaged. In
this event, have the camera position and
settingc hecked at aqualified specialist
workshop

(Y page 337).
X Stop the vehicle on solid, non-slippery and

X Get out of the vehicle. Pay attention to
traffic conditions when doing so.
X Close the driver's door.
i Vehicles equipped with MOExtende dtires
are not equipped with aTIREFIT kit at the
factory. It is therefore recommende dthat
you additionally equip your vehicle with a
TIREFIT kit if you moun ttires that do not
feature run-flat properties ,e.g. winter tires.
AT IREFIT kit can be obtained fro ma
qualified specialist workshop. MOExtended tires (tires with run-flat
properties)
General notes With MOExtende
dtires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is atotal loss of
pressure in one or mor etires. The affected
tir em ust not show any clearly visible damage.
You can recognize MOExtende dtires by the
MOExtende dmarking which appears on the
sidewall of the tire. You will fin dthis marking
nex ttot he tire size designation, the load-
bearing capacity and the speed index
(Y page 330).
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system.
If the pressur eloss warning message
appears in the multifunction display:
R Observe the instructions in the display
messages (Y page 231).
R Check the tire for damage.
R If driving on, observe the following notes. Flat tire

Press on/of fswitch 0021on th etirei nflation
compressor to ON.
The tir einflatio ncompressor is switched
on. The tire is inflated.
i First,t ire sealant is pumped into the tire.
The pressure can briefly rise to
approximately 500 kPa (5 bar/73 psi).
Do not switch off the tire inflation
compressor during this phase.
X Let the tire inflation compressor run for a
maximum of ten minutes. The tire should
then have attained apressure of at least
200 kPa (2.0 bar/29 psi).
! Do not operate the tire inflation
compressor for longer than ten minutes at
at ime without abreak. It may otherwise
overheat.
The tire inflation compressor can be
operated again once it has cooled down.
If at ire pressure of 200 kPa (2.0 ba r/29 psi)
is achieved after amaximu moften minutes,
see (Y page298).
If at ire pressure of 200 kPa (2.0 ba r/29 psi)
is not achieved after amaximu moften
minutes, see (Y page298).
i If tire sealant leaks out, allow it to dry .It
can then be removed like alayer of film.
If yourc lothes are soiled with tir esealant,
have the mcleaned with perchloroethylene
at ad ry cleaner as soon as possible.
Tir ep ressur enot reached If
ap ressure of 200 kPa (2.0 ba r/29 psi )has
not bee nachieved after ten minutes:
X Switch off the tire inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tire.
X Very slowly drive forwards or reverse
approximately 30 ft (10 m).
X Pump up the tire again.
After amaximu moften minutes, the tire
pressure must be at least 200 kPa (2.0 bar/
29 psi). G
WARNING
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 atire
pressure that is too low can significantly
impair the vehicle's braking and driving
characteristics .There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.

Therefore, place the filler hose in the plastic
bag that contained the TIREFIT kit. H
Environmental note
Have the used tir esealant bottle dispose dof
professionally, e.g. at aqualifie dspecialist
workshop.
If at ire pressure of 200 kPa (2.0 ba r/29 psi)

the tire inflation compressor.
The tire pressure mus tnow be at least
130 kPa (1.3 bar/19 psi). G
WARNING
If the required tire pressure is not reached
after driving for ashort 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
characteristics. There is arisk of accident.
Do not continue driving. Contact aqualified

X Correct the tire pressure if it is still at least
130 kPa (1.3 bar/19 psi) (for the values,
see the Tire and Loading Information
placard on the driver's side B-pillar or tire
pressure table on the fuel filler flap).

X Stow the tire sealant bottle and the tire
inflation compressor.
X Drive to the nearest qualified specialist
workshop and have the tire changed there.
X Have the tire sealant bottle and the filler
hose replaced as soon as possible at a
qualified specialist workshop.
X Have the tire sealant bottle replaced every
four years at aqualified specialist
workshop. Battery (vehicle)

WARNING
Functions relevant to safety are restricted or
no longer available if:
R the engine is not running.
R the brake system or the power steerin gis
malfunctioning.
R there is amalfunction in the voltage supply
or the vehicle's electrical system.
If your vehicle is being towed, much more
force may be necessary to steer or brake.
There is arisk of an accident.
In such cases, use atow bar. Before towing,
make sure that the steering moves freely. G
WARNING
If the weight of the vehicle to be towed or tow-
started is greater than the permissible gross
weight of your vehicle:
R the towing eye could detach itself
R the vehicle/trailer combination could
rollover.
There is arisk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the
permissible gross weight of your vehicle.

situations:
R when towing the vehicle
R in the car wash
! Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could
be damaged.
! Do not use the towing eyes for recovery
purposes as this could damage the vehicle.
If in doubt, recover the vehicle with acrane.
! When towing, pull aways lowlyand
smoothly. If the tractive power is too high,
the vehicles could be damaged.
! The vehicle can be towed amaximum of
30 miles (50km). The towing speed of
30 mph (50km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the front axle must be
raised or the entire vehicle raised and
transported.
! Do not tow with sling-type equipment.
This could damage the vehicle.
! Vehicles with automatic transmission
must not be started by tow-starting. This
could otherwise damage the transmission.
It is better to have the vehicle transported
than to have it towed.
When towing avehicle, the transmission must
be in position N.
The battery must be connected and charged.
Otherwise, you:
R cannot turn the SmartKey to position 2in
