Do not exceed the stated maximum speed.
Avoid abrupt steering and driving manoeu-
vres, and driving ove
robstacles (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 starts to shake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tyre.
After driving in emergency mode, have the
wheel rims checked at a qualified 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 there is a total loss of
pressure in one or more tyres.
MOExtended tyres may only be used in con-
junction with an active tyre pressure loss
warning system or with an active tyre 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-
tance possible depends upon:
R speed
R road condition
R outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving condi-
tions/manoeuvres, or it can be increased
through a moderate style of driving.
The maximum permissible distance which
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 a maximum 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 a tyre sealant.
You can use TIREFIT to seal punctures of up
to 4 mm, 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 a flat tyre.
There is a risk of accident.
Do not drive any further. Contact a qualified
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 a risk 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. 364

WARNING
The powe rassistance for the steering and the
brake force booster do not work when the
engine is not running. You will then need
much more effort to brake and steer the vehi-
cle. Adapt your style of driving accordingly.
It is important that you observe the safety
instructions when towing away your vehicle
(Y page 372).
The automatic transmission automatically
shifts to position Pwhen you open the driver's
or front-passenger door or when you remove
the key from the ignition lock. In order to
ensure that the automatic transmission stays
in position Nwhen towing the vehicle, you
must observe the following points:
X Make sure that the vehicle is stationary and
that the key is in position 0in the ignition
lock.
X Turn the key to position 2in the ignition
lock.
On vehicles with KEYLESS-GO, use the key
instead of the Start/Stop button
(Y page 161).
X Depress and hold the brake pedal.
X Shift the automatic transmission to posi-
tion N.
X Vehicles with manual transmission:
depress the clutch pedal.
X Engage neutral.
X Release the brake pedal.
X Release the parking brake.
X Switch on the hazard warning lamps
(Y page 129).
X Leave the key in position 2in the ignition
lock.
i When towing with the hazard warning
lamps switched on, use the combination
switch as usual to signal achange of direc-
tion. In this case, only the turn signals for
the desired direction flash. When the com- bination switch is reset, the hazard warning
lamps start flashing again. Transporting the vehicle
! Only lash the vehicle down by the wheels
or wheel rims, not by parts of the vehicle
such as axle or steering components. Oth-
erwise, the vehicle could be damaged.
The towing eyes or trailer tow hitch can be
used to pull the vehicle onto a trailer or trans-
porter if you wish to transport it.
X Vehicles with manual transmission:
shift to neutral.
X Vehicles with automatic transmission:
turn the key to position 2in the ignition
lock.
X Shift the automatic transmission to posi-
tion N.
As soon as the vehicle is loaded:
X Prevent the vehicle from rolling away by
applying the parking brake.
X Vehicles with manual transmission:
engage first or reverse gear.
X Vehicles with automatic transmission:
shift the automatic transmission to posi-
tion P.
X Turn the key in the ignition lock to position
0and remove the key from the ignition
lock.
X Secure the vehicle. Notes for 4MATIC vehicles
! Vehicles with 4MATIC must not be towed
with the front or rear axle raised; otherwise,
the transmission may be damaged.
If the vehicle has transmission damage or
damage to the front or rear axle, have it trans-
ported on a transporter or trailer.
