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.
200Vehicle care
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).

6. Press the SET/CLR button to
begin the sensor matching process. A message requesting
acceptance of the process should
display.
7. Press the SET/CLR button again
to confirm the selection. The horn sounds twice to signal the
receiver is in relearn mode.
8. Start with the left side front wheel.
9. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activate
the TPMS sensor. A horn chirp
confirms that the sensor
identification code has been
matched to this wheel position.
10. Proceed to the right side front wheel, and repeat the procedure
in Step 9.
11. Proceed to the right side rear wheel, and repeat the procedure
in Step 9.
12. Proceed to the left side rear wheel, and repeat the procedure
in Step 9. The horn sounds twice
to indicate the sensoridentification code has been
matched to the left side rear
wheel, and the TPMS sensor
matching process is no longer
active.
13. Turn off the ignition.
14. Set all four tyres to the recommended air pressure level
as indicated on the tyre pressure
label.
15. Ensure the tyre loading status is set according selected pressure
3 93.
Temperature dependency Tyre pressure depends on the
temperature of the tyre. During
driving tyre temperature and pressure increase.
The tyre pressure value displayed in
the DIC shows the actual tyre
pressure. Therefore it is important to
check tyre pressure with cold tyres.
Tread depth Check tread depth at regular
intervals.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.

Jacking position for liftingplatform
Rear arm position of the lifting
platform centrically under the recess
of the sill.
Front arm position of the lifting
platform at the underbody.
Spare wheel Some vehicles are equipped with a
tyre repair kit instead of a 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 always 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.
