!Do not use the towing eye for recovery. This
could damage the vehicle. If in doubt, have
the vehicle recovered using acrane.
!When towing, pull aways lowly and
smoothly. 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.
!Do not tow with sling-type equipment. This
could damage the vehicle.
!The vehicle can be towed amaximum of
30 miles (50km). The towing speed of 30 mph (50 km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the entire vehicle must be
raised and transported.
It is better to have the vehicle transported than
to have it towed away.
If the vehicle has suffered transmission damage,
have it transported on atransporter or trailer.
The automatic transmission must be in position N when the vehicle is being towed. If the auto-
matic transmission cannot be shifted to position
N,h ave the vehicle transported on atransporter
or trailer.
The battery must be connected and charged.
Otherwise, you:
Rcannot turn the SmartKey to position 2in the
ignition lock
Rcannot release the electric parking brake
Rcannot shift the automatic transmission to
position N
Disarm the automatic locking feature before the vehicle is towed (
Ypage 81). You could other-
wise be locked out when pushing or towing the
vehicle.
Installing/removing the towing eye
Installingt he towing eye
The brackets for the screw-in towing eye are
located in the bumpers. They are at the rear and
at the front,u nder covers:.
XRemove the towing eye from the vehicle tool
kit (Ypage 300).
XPress the mark on cover :inwards and
remove.
XScrew in the towing eye clockwise as far as it will go and tighten it.
Removing the towing eye
XUnscrew and remove the towing eye.
XAttach cover :to the bumper and press until
it engages.
XPut the towing eye back into the vehicle tool
kit.
Towing the vehiclew ith the rear axle
raised
Only vehicles without 4MATIC can be towed
with the rear axle raised.
!Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised, as doing so will damage the transmission.
Vehicles with 4MATIC may either be towed away
with both axles on the ground or be loadedu p
and transported.

!Vehicles with automatic transmission must
not be towed with the rear axle raised. The
vehicle/trailer combination may otherwise
swerve or even roll over.
Towing avehiclew ith both axles on
the ground
The automatic transmission automaticallys hifts
to position Pwhen you open the driver's or front-
passenger door or when you remove the Smart-
Key from the ignition lock. In order to ensure
that the automatic transmission stays in posi-
tion Nwhen towing the vehicle, you must
observe the following points:
XMake sure that the vehicle is stationary.
XTurn the SmartKey to position 2in the ignition
lock.
XDepress and hold the brake pedal.
XShift the automatic transmission to position
N.
XLeave the SmartKey in position 2in the igni-
tion lock.
XRelease the brake pedal.
XRelease the electric parking brake.
XSwitch on the hazard warning lamps
(Ypage 112).
In order to signal achange of direction when
towing the vehicle with the hazard warning
lamps switched on, use the combination switch
as usual. In this case, only the indicator lamps
for the direction of travel flash. After resetting
the combination switch, the hazard warning
lamp starts flashing again.
Transporting the vehicle
4MATIC vehicles/vehiclesw ith auto-
matic transmission
!When the vehicle is loadedf or transport, the
front and rear axles must be stationary and on the same transportation vehicle. Positioning
over the connection point of the transport
vehicle is not permitted. The drive train may
otherwise be damaged.
All vehicles
!You may only secure the vehicle by the
wheels, not by parts of the vehicle such as
axle or steering components. Otherwise, the
vehicle could be damaged.
The towing eye can be used to pull the vehicle
onto atrailer or transporter for transporting pur-
poses.
XTurn the SmartKey to position 2in the ignition
lock.
XShift the automatic transmission to position
N.
As soon as the vehicleh as been loaded:
XPrevent the vehicle from rolling awayb y

316Operation
Wheels and tires

Turn on ESP®and adapt your driving style
accordingly. When the outside temperature
falls below 10 †, use M+S tires.
iDifferent driving styles may lead to high tire
wear and the tires may reach the minimum
tire tread depth after only ashort time.
Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As aresult, you could lose control of
your vehicle. There is arisk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Check wheels and tires for damage at least once
am onth. Check wheels and tires after driving
off-road or on rough roads. Damaged wheels
can cause aloss of tire pressure. Pay particular
attention to damage such as:
Rcuts in the tires
Rpunctures
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width of
the tire (
Ypage 317). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tire surface.
All wheels must have avalve cap to protec tthe
valve against dirt and moisture. Do not mount
anything ontot he valve other than the standard
valve cap or other valve caps approved by
Mercedes-Benz for your vehicle. Do not use any
other valve caps or systems, e.g. tire pressure
monitoring systems.
Regularly check the pressure of all the tires par-
ticularly prior to long trips. Adjust the tire pres-
sure as necessary (
Ypage 319).
The service life of tires depends, among other
things, on the following factors:
Rdriving style
Rtire pressure
Rdistance covered
Notes on tire tread
GWARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where speed is not adapted to suit the driving con-
ditions. There is arisk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Marking :shows where the bar indicator
(arrow) for tread wear is integrated into the tire
tread.
Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread.
They are visible once atread depth of approx-
imately áin (1.6 mm) has been reached. If this
is the case, the tire is so worn that it must be
replaced.
Selecting, mounting and replacing
tires
ROnly mount tires and wheels of the same type
and make.

Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with atire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provid esufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than ãin
(4 mm) must be replaced immediately.
At temperatures belo w45‡ (+7 †), use winter
tires or all-season tires. Bot htype soft ire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possibl egrip in wintry road conditions.
Only these tires wil lallow driving safety systems
such as ABS and ESP
®to function optimally in
winter. Theset ires have beend eveloped specif-
ically for driving in snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximu mpermissible
speeds pecified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
XCheck the tire pressures (Ypag e322).
XRestart the tire pressure monitor
(Ypag e325).
