cle.
! Observe the following points when towing
with atow rope:
R Secure the tow rope on the same side on
both vehicles.
R Make sure that the tow rope is not longer
than legallyp ermitted. Mark the tow rope in
the middle, e.g. with awhite cloth
(30 x30c m).This will make other road
users aware that avehicle is being towed.
R Only secure the tow cable to the towing
eyes or, if available, to the trailer tow hitch.
R Observe the brake lamps of the towing
vehicle while driving. Always maintain adis-
tance adistance so that the tow rope does
not sag.
R Do not use steel cables or chains to tow
your vehicle. You could otherwise damage
the vehicle.
! Do not use the trailer tow hitch for recovery
or towing. Do not use the towing eye for
recovery. This could damage the vehicle. If in doubt, have the vehicle recovered using a
crane.
! Pull away smoothly when towing away or
tow-starting avehicle. If the tractive power is
too high, the vehicles could be damaged.
! Shift the automatic transmission to
Nand
do not open the driver's or front passenger's
door during towing. The automatic transmis-
sion may otherwise shift to position P,which
could damage the transmission.
! You may tow the vehicle for
amaximum of
50km.At owing speed of 50 km/h must not
be exceeded.
For towing distances over 50 km, the entire
vehicle must be lifted up and transported.
Observe the legal requirements for the relevant countries when towing.
It is better to have the vehicle transported than
to have it towed.
If the vehicle has suffered transmission damage,
have it transported on atransporter or trailer.
Vehicles with automatic transmission: when
towing avehicle, the automatic transmission
must be in position N.Ifthe automatic trans-
mission cannot be shifted to position N,have the vehicle transported on
atransporter or
trailer.
The battery must be connected and charged.
Otherwise, you:
R cannot turn the key to position 2in the igni-
tion lock
R cannot release the electric parking brake
R cannot shift the transmission to position Non
vehicles with automatic transmission
Deactivate the automatic locking feature before towing the vehicle (Y page 88). You could oth-
erwise be locked out when pushing or towing
the vehicle.
Deactivate tow-away protection before the vehi- cle is towed away (Y page 79). Fitting/removing the towing eye
Fitting the towing eye The mountings for the removable towing eyes
are located in the bumpers. They are at the rear
and at the front,u nder covers:.
X Remove the towing eye from the vehicle tool
kit (Y page 336).
X Press the mark on cover :inwards and
remove.
X Screw in the towing eye clockwise as far as it
will go and tighten it.
Vehicles with atrailer tow hitch do not have a

Notes on the vehicle equipment
–always fit the
vehicle:
R with tyres of the same size across an axle
(left/right)
R with the same type of tyres at agiven time
(summer tyres, winter tyres, MOExtended
tyres)
Exception: it is permissible to fit adifferent
type or make in the event of aflat tyre.
Observe the "MOExtended tyres (tyres with
run-flat characteristics)" section
(Y page 337).
Vehicles with MOExtended tyres are not equip-
ped with aTIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
yourv ehicle with aTIREFIT kit if you fit tyres that
do not feature run-flat characteristics, e.g. win-
ter tyres. ATIREFIT kit can be obtained from a
qualifieds pecialist workshop. Emergencys

G
WARNING
The wheel/tyre dimensions and the tyre type of the spare wheel/emergency spare wheel
and the wheel to be replaced may differ. Fit-
ting aspare wheel/emergency spare wheel
may severely impairt he driving characteris-
tics. There is arisk of accident.
To prevent hazardou ssituations:
R Adapt yourd riving style accordingly and
drive carefully.
R Never fit more than one spare wheel/emer-
gency spare wheel if the dimensions are
different to those of the wheel being
replaced.
R Only use aspare wheel/emergency spare
wheel briefly if the dimensions are different to those of the wheel being replaced.
R Do not switch off ESP ®
.
R Have the spare wheel/emergency spare
wheel in questionr eplaced at the nearest
qualifieds pecialist workshop. Make sure
that the wheel/tyre dimensions and tyre
type are correct. When using an emergency spare wheel or spare
wheel of adifferent size, you must not exceed
the maximum speed of 80 km/h.
Snow chains must not be fitted to emergency
spare wheels. General notes
You can ask for information regarding permitted
emergency spare wheelsataM ercedes-Benz
Service Centre.
You shouldr egularly check the pressure of all
yourt yres, including the emergency spare
wheel,p articularly prior to long trips, and cor-
rect the pressure as necessary (Y page 356).
The valueont he wheel is valid.
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the
time restriction on use as well as the speed lim- itation specifie donthe emergency spare wheel.
Replace the tyres after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning sys- tem or the tyre pressure monitor cannot func-
tion reliably.O nly restart the tyre pressure loss
warning system or tyre pressure monitor when
the defective wheel has been replaced with a
new wheel.
Vehicles with tyre pressure monitor: after
fitting an emergency spare wheel,t he system
may still display the tyre pressure of the
removed wheel for afew minutes. The valued is-
played for the position where the emergency
spare wheel is fitted is not the same as the cur- rent tyre pressure of the emergency spare
wheel. Removing the emergencys
