Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

WARNING
If wheels and tyres of the wrong size are used, the wheel brakes or suspension components
may be damaged. There is a risk of an acci-
dent.
Always replace wheels and tyres with those
that fulfil the specifications of the original
part.
When replacing wheels, make sure to fit the
correct:
R designation
R type
When replacing tyres, make sure to fit the
correct:

R type G
WARNING
A flat tyre severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of accident.
Tyres without run-flat characteristics:
R do not drive with a flat tyre.
R immediately replace the flat tyre with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop. Tyres with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tyres (tyres
with run-flat characteristics).
Accessories that are not approved for your
vehicle by Mercedes-Benz or are not being
used correctly can impair the operating
safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and enquire about:
R suitability
R legal stipulations
R factory recommendations
Information on the dimensions and types of
wheels and tyres for your vehicle can be
found under "Wheel/tyre combinations"
(Y page 378)(Y page 380).
Information on air pressure for the tyres on
your vehicle can be found:
R on the tyre pressure label on the fuel filler
flap (Y page 178)
R under "Tyre pressure" (Y page 367)
Modification work on the brake system and
wheels is not permitted. The use of wheel
spacers or brake dust shields is not permit-
ted. This invalidates the general operating
permit for the vehicle.
i Further information on wheels and tyres
can be obtained at any qualified specialist
workshop. Operation
Information on driving
Check the tyre pressures when the vehicle is
heavily laden and, if necessary, adjust.
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that the wheels or tyres are damaged. If you sus-
pect that a tyre is defective, reduce your
speed immediately. Stop the vehicle as soon 364

Changing a wheel
Flat tyre
You can find information on what to do in the event of a flat tyre in the "Breakdown assis-
tance" section (Y page 347). Information on
driving with MOExtended tyres in the event of a flat tyre can be found under "Breakdown
assistance" (Y page 347).
Vehicles with an emergency spare wheel: in the event of a flat tyre, the emergency
spare wheel is fitted according to the descrip-
tion under "Fitting a wheel" (Y page 374). Interchanging the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions. The wheel brakes or suspension components may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with a tyre pressure
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Only have tyres changed at a qualified spe- cialist workshop. Changing a wheel
373Wheels and tyres Z
Further information about wheels, tyres
and approved combinations can be
obtained from any qualified specialist
workshop.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not fit
used tyres if you have no information about their previous usage.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as a result of driving over obstacles
increases.
Overview of abbreviations used in the follow- ing tyre tables:
R BA: both axles
R FA: front axle
R RA: rear axle
You will find a table with recommended tyre
pressures for various operating conditions on
the inside of your vehicle's fuel filler flap. For
further information on tyre pressure, see
(Y page 367). Check tyre pressures regularly
and only when the tyres are cold.
Notes on the vehicle equipment – always fit
the vehicle:
R with tyres of the same size on a given axle
(left/right)
R with the same type of tyres at a given time
(summer tyres, winter tyres, MOExtended
tyres)
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It
is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit
if you fit tyres that do not feature run-flat
characteristics, e.g. winter tyres. A TIREFIT kit can be obtained from a qualified spe-
cialist workshop.

fitted at the factory in all countries. Wheel and tyre combinations
