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
bracket at the back for the screw-in towing eye. Connect the towbar to the trailer tow hitch

wear down to the minimum tyre tread depth
after less mileage. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As aresult, you could lose control of
your vehicle. There is arisk of accident.
Check the tyres regularly for signs of damage and replace any damaged tyres immediately.
Check wheels and tyres for damage at least
onc eam onth. Check wheels and tyres after
driving off-road or on rough roads. Damaged
wheels can cause aloss of tyre pressure. Pay
particular attention to damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on the tyres
R deformation or severe corrosion on wheels
Regularly chec kthe tyre tread depth and the
condition of the tread across the whole width of
the tyre (Y page 354).Ifnecessary, turn the
fron twheels to full lock in order to inspec tthe
inne rside of the tyre surface.
All wheels must have avalve cap to protect the
valve against dirt and moisture. Do not fit any-
thin gontot he valve other than the standard
valve cap or other valve caps approved for your vehicle by Mercedes-Benz.Don ot fit any other
valve caps or systems ,e.g. tyre pressure moni-
torin gsystems.
Regularly chec kthe pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 356).
Observe the notes on the emergency spare

WARNING
Insufficien ttyre tread will reduce tyre trac-
tion .The tyre is no longer able to dissipate
water. This means that on wet road surfaces, the risk of aquaplaning increases, in particularwhere speed is not adapted to suit the driving
conditions. There is arisk of accident.
If the tyre pressure is too high or too low, tyres may exhibit differen tlevels of wear at differ-
ent location sonthe tyre tread. Thus, you
should regularly chec kthe tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3mm
R M+S tyres: 4mm
For safety reasons ,replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached. Selecting, fitting and replacing tyres
G
WARNING
Exceeding the stated tyre load-bearing capa-
city and the approved maximum speed could
lead to tyre damage or the tyre bursting. There is ar isk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the
tyre load ratin gand speed ratin grequired for
your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These require-
ment scan stipulate aspecific tyre type for your
vehicle. Furthermore, the use of certain tyre
types in certain regions and areas of operation
can be highly beneficial. You can find further 354

WARNING
If you fit unsuitabl eaccessories onto tyre
valves, the tyre valve smay be overloadeda nd
malfunction, which can caus etyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can alsor esult in tyre pressure loss. There is a
risk of accident.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
yourv ehicleonto the tyre valve. G
WARNING
If the tyre pressure drops repeatedly ,the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in atyre
blow-out. There is arisk of accident.
R Check the tyre for foreig nobjects.
R Check whethe rthe whee lislosing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact aqualified specialist workshop. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days.
The recommende dtyre pressures for various
operating conditions can be found in the tyre
pressure table on the fuel filler flap
(Y page1 67).
Operation with an emergency spare wheel:
information on operation with an emergency
spar ewhee lcan be found in the genera lnotes in
the "Emergency spar ewheel" section
(Y page3 67).
Operation with atrailer: the applicable value
for the rear axle is the maximu mtyre pressure
valu estated in the table insid ethe fuel filler flap.
Additionally, the tyre pressure table may also
state tyre pressures for different loadc ondi-
tions. These are defined in the table as different numbers of passengers and amounts of lug-
gage .The actua lnumber of seats may vary ;for
more information, please refer to the vehicle's
registration documents.
If tyre sizes are not specified ,the tyre pressures
stated on the tyre pressure table apply for all
tyres approved for this vehicle. If
at yre size precedes atyre pressure, the fol-
lowing tyre pressure information is only vali dfor
that tyre size.
Use asuitable pressure gauge to check the tyre
pressure. The outer appearance of atyre does
not permi tany reliablec onclusion about the tyre
pressure. On vehicles fitted with the electronic
tyre pressure monitor, the tyre pressure can be checked using the on-board computer.
If possible,o nly correct tyre pressures when the
tyres are cold.
The tyres are cold:
R if the vehicl ehas been parked with the tyres
out of direct sunlight for at least three hours
and
R if the vehicl ehas not been drive nfurther than
1.6 km
Depending on the ambient temperature, the
vehicl espee dand the loadont he tyres, the tyre
temperature and thus the tyre pressure changes
by approximatel y10k Pa (0.1 bar/1.5 psi) per
10 †. Take this into account when checking the
pressure of warm tyres. Only correct the tyre
pressure if it is too low for the current operating conditions.
Driving with tyre pressure that is too high or too
low can:
R shorten the service life of the tyres
R caus eincreased tyre damage
R have anegative effect on handling character-
istics and thus driving safety (e.g. aquaplan-
ing)
The tyre pressure values given for low loads are minimu mvalues which offer you good ride com-
fort characteristics.
