Information on driving
If the vehicle is heavily loaded, check the tire
pressures and correct them if necessary.
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you
suspect that atire is defective, reduce your
speed immediately. Stop the vehicle as soon
as possible to check the wheels and tires for
damage. Hidden tire damage could also be
causing the unusual handling characteristics.
If you find no signs of damage, have the tires 334
OperationWheels and tires

and wheels checked at
aqualified specialist
workshop.
When parking your vehicle ,makes ure that
th et ires do no tget deformed by the curb or
other obstacles. If it is necessary to drive over
curbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle.
Otherwise, the tires, particularly the
sidewalls, may be damaged. Regular checking of wheels and tires
G
WARNING
Damaged tires can cause tire inflation
pressure 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.
Regularly chec kthe wheels and tires of your
vehicle for damage at least once amonth, as
well as after driving off-road or on rough
roads. Damaged wheels can cause aloss of
tire pressure. Pay particular attention to
damage such as:
R cuts in the tires
R punctures
R tears in the tires
R bulges on tires
R deformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width
of the tire (Y page 335). 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 protect
the valve against dirt and moisture. Do not
mount anything onto the valve other than the
standard valve cap or other valve caps
approved by Mercedes-Ben zfor 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
particularly prior to long trips. Adjust the tire
pressure as necessary (Y
page 338).
Observe the notes on the emergenc yspare
wheel (Y page 367).
The service life of tires depends, among other
things, on the following factors:
R Drivin gstyle
R Tire pressure
R Distance covered Important safety notes on the tire
tread
G
WARNING
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
conditions. There is arisk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at
different 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:
R Summer tires: 0015in (3 mm)
R M+S tires: 001Fin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached. Operation

tires
R Only mount tires and wheels of the same
type and make.
Exception: it is permissible to install a
different type or make in the event of aflat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section
(Y page3 21).
R Only mount tires of the correct size onto
the wheels.
R Break in new tires at moderate speeds for
the first 60 mile s(100 km) .They only reach
their full performance after this distance.
R Do not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
R Replace the tires after six years at the
latest, regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 367). MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is atotal loss of
pressure in one or more tires.
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system or with an active tire pressure
monitor and on wheels specifically tested by
Mercedes-Benz. Notes on driving with MOExtended tires with
af
lat tire (Y page 321).
i Vehicles equipped with MOExtended tires
are not equipped with aTIREFIT kit at the
factory. It is therefore recommended that
you additionall yequip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
AT IREFIT kit can be obtained from a
qualified specialist workshop. Winter operation
General notes
Have your vehicle winterproofed at aqualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing awheel"
section (Y page 357). Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity significantly ,and
therefore traction and braking power as well.
Change the tires on you rvehicle to
M+S tires. Using summer tires at very cold
temperatures could cause crack stoform,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility
for this type of damage. M+S tires
G
WARNING
M+S tires with atiret read dept hofless than
001F in (4 mm )are no tsuitable for use in winter
and do no tprovide sufficient traction .There
is ar iskofana ccident.
M+S tires wit hatread dept hofless than 001F
in (4 mm )must be replace dimmediately.
At temperatures below 45 ‡(+7 †), use
winter tires or all-weather tires. Both type sof
tir ea re identified by th eM+S marking. 336
Winte
roperationWheels and tires

Only winter tires bearing the
0012snowflake
symbol in addition to the M+S marking
provide the best possibleg rip in wintry road
conditions.
Only these tires will allowd riving safety
systems such as ABS and ESP ®
to function
optimally in winter. These tires have been
developeds pecificallyfor driving in snow.
Use M+S tires of the same make and tread on
all wheels to maintain safe handling
characteristics.
Alwayso bserve the maximum permissible
speed specified for the M+S tires you have
mounted.
Once the winter tires are mounted:
X Check the tire pressures (Y page 341).
X Vehiclesf or Canada: restart the tire
pressure loss warning system
(Y page 342).
X Restart the tire pressure monitor
(Y page 342).

emergency spare wheel, see (Y page 367).Snow chains
G
WARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is arisk of an accident.
To avoid hazardous situations:
R never install snow chains to the front
wheels
R always install snow chains in pairs to the
rear wheels.
! On vehicles with AIRMATIC, you must
drive at raised vehicle level if snow chains
have been mounted. The vehicle may
otherwise be damaged.
! On some tire sizes there is not enough
space for snow chains. To avoid damage to the vehicle or tires, observe the "Wheel and
tire combinations" section under "Tires and
wheels".
For safety reasons, Mercedes-Benz
recommends that you only use snow chains
that have been speciallya pproved for your
vehicle by Mercedes-Benz,ora re of a
corresponding standard of quality.
If you intend to mount snow chains, please
bear the following points in mind:
R Snow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel-tire combinations (Y page 362).
R Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as
possiblew hen you come to aroad that is
not snow-covered.
R Local regulations may restrict the use of
snow chains. Observe the appropriate
regulations if you wish to mount snow
chains.
R Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
i You may wish to deactivate ESP ®
when
pulling away with snow chains installed
