Vehicle care199Wheels and tyresTyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb
when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
We recommend not swapping the
front wheels with the rear wheels and vice versa, as this can affect vehicle
stability. Always use less worn tyres
on the rear axle.
Winter tyres Winter tyres improve driving safety attemperatures below 7 °C and shouldtherefore be fitted on all wheels.
All tyre sizes are permitted as winter
tyres 3 237.
Tyre size 185/60 R 15 is only
permitted as winter tyre.In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
Tyre designations E.g. 195/55 R 16 95 H195=tyre width, mm55=cross-section ratio (tyre height
to tyre width), %R=belt type: RadialRF=type: RunFlat16=wheel diameter, inches95=load index e.g. 95 is equivalent
to 690 kgH=speed code letter
Speed code letter:
Q=up to 100 mphS=up to 112 mphT=up to 118 mphH=up to 130 mphV=up to 150 mphW=up to 168 mphDirectional tyres
Directional tyres must be mounted so that they rotate in the correct
direction. The proper rotation
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at least every 14 days and before any
long journey. Do not forget the spare
wheel.
This also applies to vehicles with tyre pressure monitoring system.
Unscrew the valve cap.

Tyre pressure 3 237.
The tyre pressure information label on the right door frame indicates theoriginal equipment tyres and the
correspondent tyre pressures.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options.
For the correct tyre pressure value,
follow the procedure below:
■ Identify the engine identifier code. Engine data 3 230.
■ Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 237.For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
If the tyre pressure must be reduced
or increased, switch off ignition. After
adjusting tyre pressure switch on
ignition and select the relevant setting on the page Tyre load in the Driver
Information Centre 3 93.
Tyre pressure monitoring
system The tyre pressure monitoring system
(TPMS) checks the pressure of all
four tyres once a minute when vehicle speed exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The current tyre pressures can be
shown in the Vehicle Menu in the
Driver Information Centre (DIC).

Vehicle care205
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
Tyres age, even if they are not used.
We recommend tyre replacement
every six years.
Changing tyre and wheel
size
If tyres of a different size than those fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and to make other
vehicle modifications.
After converting to a different tyre size, have the label with tyre
pressures replaced.Caution
When converting to wheels with 14 inch diameter, the ground
clearance will be reduced. This
must be considered when passing
over obstacles.
9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.

214Vehicle care
Have the defective tyre renewed orrepaired as soon as possible.
Jacking position for lifting
platform
Rear arm position of the lifting
platform located centrally under the
recess of the sill.
Front arm position of the lifting platform at the underbody.
Spare wheel If mounting a spare wheel, which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.
The spare wheel has a steel rim.
Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
The spare wheel is located in the load
compartment beneath the floor
covering. It is secured with a wing nut.
Fitting a double load-bay floor in this
case in the upper position 3 69.
