Tyres and wheels
!
Fit single new tyres on the front wheels
first if tyres of the same size are fitted
on the front and rear wheels.
! Remove the rust from corr oded steel
wh eels and repaint them.
! Replace the tyres at least every
6years, irrespective of their degree
of wear.
! Adjust the tyre pressures if the vehicle
is laden – see Fuel filler cap
(= page 241).
! Storetyres ina cool, dry place, preferably in
the dark. Protect the tyres from oil, grease,
petrol and diesel.
Do not clean your wheels with acidic wheel
cl eaners since these could corrode the wheel
bolts. Tyres with a specified direction of rotation
offer additional benefi
ts,e.g. with regard
to aquaplaning. These benefits are only
available to you ifthe correct direction of
rotation isobserved.
An arrow on the sidewa llof the tyre indi-
cates its correct direction of rotation.
i A spare wheel* may also be fi tted against
th edirection of rotatio n. The MO
Extended run-flat system allows
you to cont inue driving your vehicle, even
if there is a complete loss of air in one or
more tyres.
You can only use the MO Extendedrun-flat
system in conjunction with the tyre pres-
sure loss warning system.
For notes about driving in the event of a
flat tyre, see the Practical advice section

Operation
Tyres and wheels
Only correct the tyre pressures when the
tyres are cold.
The pressures of warm tyres should only
be corrected if the yare too low for the cur-
rent operat ing condi tions. Warm tyres al-
ways have higher tyre pressures than cold
tyres.
You will find a table oftyre pressures for
va rious operating conditions on the inside
of the veh icle's fuel filler flap. i
Tyre pressure values given for low loads are
mi nimum value swhich offer you good ride com-
fort charact eristics.
You can, however, also usethe value sfor higher
lo ads. These are permissible and do not adverse-
ly aff ect the running of thevehicle. However, ride
co mfort will be impaired to som edegree.
Als ocheck thet yre pressure of thespare
wheel*.
Ty re pressure changes by approximately
0. 1b ar for every 10 °C change in ambient
temperature. If you measure the tyre pres-
sures indoors where the temperature dif-
fers from the outside temperature, you will
have to correct the measured values ac-
cor dingly.
When the vehicle isdriven, the tyre tem-
perature, and wi thit the tyre pressure, in-
crease as a function of the road speed and
the load on the tyres. During the journey, the tyre pressure loss
warning system monitors the set tyre pres-
sure by comparing the speed of rotation of
the
wheels. This enables the system to de-
tect whether there has been a significant
drop in tyre pressure in one of the tyres. If
the rotation speed of a wheel changes be-
cause of a drop in tyre pressure, a corre-
sponding warning message appears in the
multi -function display. Tyre pr
essure G

258 Operation
Winter driving
Do not exceed the maximum permissible
spee d of 50 km /h. Remove the snow
chains as soon as pos sible if you are no
longer driving on snow-covered roads.
i Youmay wish to deactivate ESP when pull-
ing away on snow chains ( =
page 70). This will
help you to achieve an effective cutting action.
If you are intending to fit snow chains,
please remember the follow ing:
! Snow chains cannot be fitted on all
whee l/tyre combinations.
! Fit snow chains only to the rear wheels.
Comply with the manufacturer's instal-
lat ion instructions.
! Mercedes-Benz recommends that, for
safety reasons, you only use snow
chains wh ich have been approved for
Mercedes-Benz.
! Youmust not fit snow chains to AMG tyres. You should drive particularly carefully on
icy roads. Avoid sudden accelerati
on,
steering mo vements and braking.
If the vehicle threatens to skid or cannot
be brought to a standstill at a low speed:
! shift in toneut ral
! move the selector lever to N
! try to keep the vehicle under control
using corrective steering G
Risk of accident If you fit the spare wheel
*when driving with
winter tyres, pl ease be awarethat driving
stability will beimp aired owing to unstable
cornering characteristics cause dby the dif-
ferent tyres. You should ther efore adapt
your driving style and drive carefully.
Have the spare wheel* changed at the near-
est qualifi edspecialist workshop which has
the necessary specia list knowledge and
tools to carry out the work required.
Mercedes-Benz recomme nds that youuse a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-re lated systems must be car-
ried out at a qualified specialist workshop. Snow chains Winter driving

Operation
Trailer towing
! You should not exceed a maximum
speed of 80 km /h, even incountries
where higher speeds are permitted.
! Avoid sudden braking. Instead, apply
the brake lightly at first, to allow the
trailer to overrun. Then increase the
braking for cerapidly.
! If the trailer starts to swing, reduce
your speed, do not attempt corrective
steering, and brake if necessary. On no
account should you attem pttodraw
the vehicle /trailer combination out by
increasing your speed.
! The gradient-climbing capabi lities from
a standstill are correct for sea level.
When driving in mountainous areas,
note that the power output of the en-
gine, and with itits gradient-climbing
capability from a standstill, decreases
with increasing altitude.
! Do not uncouple a trai ler with anoverrun
brake when the brake is engaged. The spring
action of the overrunning brake mechani sm
could damage the bumper. 6
Fold out the socket under the vehicle.
6 Remove the locked prot ective cap on
the handwheel.
6 Unlock the lock on the handwheel
usin g the key.
6 Hold the ball coupli ngfirmly. Lift the
handwheel off the ball coupling and
turn the handwheel clockwise until it
engages.
The red marking on the handwheel is
aligned with the white marking.
6 Remove the ball coupling by pulling
downwards.
6 Press the ball coupling cover into the
ball coupling recess.
Make sure that the cover is fitted se-
curely. Stowing the ball coupling
