Wheels and tyres
The
speed rating code
⇒ page 238, New tyres and wheels determines the
following
speed limits for winter tyres:
⇒
max. 160 km/h
max. 180 km/h
max. 190 km/h
max. 210 km/h
In some countries, vehicles which can exceed the speed rating of the fitted
tyre must have an appropriate sticker in the driver's field of view. These
stickers are available from your Authorised Service Centre. The legal require-
ments of each country must be followed.
Do not have winter tyres fitted for unnecessarily long periods. Vehicles with
summer tyres handle better when the roads are free of snow and ice.
If you have a flat tyre, please refer to the notes on the spare wheel
⇒ page 238, New tyres and wheels.

The maximum speed for the winter tyres must not be exceeded. Other-
wise, this could lead to tyre damage and risk of accident.
For the sake of the environment
Fit your summer tyres again as soon as possible. They are quieter, do not
wear so quickly and reduce fuel consumption.
Snow chains
Snow chains are only permitted on front wheels and only for tyres
195/65R15 and 205/55R16. These tyres may only be fitted with fine-pitch
link chains which do not protrude more than 15 mm
⇒ page 272. For
235/35R19 tyres, the use of snow chains is not permitted.
Q
S
T
H
Other tyres may use fine-pitch links which do not protrude more than 9 mm,
including tension device.
Remove wheel hub covers and trim rings before fitting snow chains. For
safety reasons cover caps, available in any Authorised Service Centre, must
then be fitted over the wheel bolts.
WARNING
Snow chains should be correctly tightened in accordance with the manu-
facturer's instructions. This will prevent the chains coming into contact
with the wheel housing.
CAUTION
Remove the snow chains to drive on roads without snow. Otherwise they
will impair
handling, damage the tyres and wear out very quickly.
Note
● In some countries, the speed limit for using snow chains is 50 km/h.
The legal requirements of the country should be followed.
● We recommend that you ask your Authorised Service Centre for informa-
tion about appropriate wheel, tyre and snow chain size.

Tools, tyre repair kit and spare wheel
Vehicle Tools
The vehicle onboard tools are located under the floor panel
in the luggage compartment.
– Lift the cover of the luggage compartment, by pulling it up with
a finger in the fitting.
– Take the on-board tools out of the vehicle.
The tool kit includes:
● Jack*
● Hook for removing wheel covers* or hub caps*
● Box spanner for wheel bolts*
● Towing eye
● Adapter for the anti-theft wheel bolts*
Some of the items listed are only provided
in certain model versions, or are
optional extras.
WARNING
●
The factory-supplied jack* is only designed for changing wheels on
this model. On no account attempt to use it for lifting heavier vehicles or
other loads. Risk of injury.
●
Use the jack* only on firm, level ground.
WARNING (Continued)
●
Never start the engine when the vehicle is on the jack. Risk of acci-
dent.
●
If work is to be carried out underneath the vehicle, this must be se-
cured by suitable stands. Otherwise, there is a risk of injury.
Compact temporary spare wheel* (emergency wheel)
The compact spare wheel (emergency wheel for vehicles
without the anti-puncture kit) should only be used when
strictly necessary.
Fig. 154 Luggage com-
partment. Access to the
spare wheel
The temporary spare wheel is stored under the floor panel in the luggage
compartment and is attached by a thumbnut.

If and when
How to use the temporary spare wheel
Should you ever have a punctured tyre, the
temporary spare wheel is only
intended for temporary use until you can reach a workshop. The standard-
size road wheel should be replaced as soon as possible.
Please note the following restrictions when using the temporary spare
wheel. This spare wheel has been specially designed for your vehicle, thus,
it cannot be changed with the spare wheel from another vehicle.
No other type of tyre (normal summer or winter tyre) may be fitted on the
compact temporary spare wheel rim.
Snow chains
For technical reasons, snow chains must
not be
used on the compact tem-
porary spare wheel.
If you have a puncture on one of the
front wheels when using snow chains,
fit the compact temporary spare in place of one of the rear wheels. You can
then attach the snow chains to the wheel taken from the rear and use this
wheel to replace the punctured front wheel.
WARNING
●
The tyre pressures must be checked and corrected as soon as possi-
ble. The emergency tyre pressure for dimensions 125/70R16 125/70R18
135/90R16 is 4.2 bar; for all other tyre dimensions please refer to the la-
bel on the fuel cap. Failure to do so could result in an accident.
●
Do not drive faster than 80 km/h. Higher speeds can cause an acci-
dent.
●
Avoid heavy acceleration, hard braking and fast cornering. Risk of ac-
cident.
●
Never use two or more compact spare tyres at the same time, risk of
accident.
●
No other type of tyre (normal summer or winter tyre) may be fitted on
the compact temporary spare wheel rim.
Note
● Vehicles with Brembo brakes must never use emergency wheels. These
vehicles are supplied with a tyre repair kit.
Tyre repair kit*
The tyre repair kit (for vehicles not including a spare wheel)
is stored under the floor panel in the luggage compartment.
Your vehicle is equipped with the Tyre Mobility System “Tyre repair kit”.
The tyre repair kit consists of a container with sealing compound to repair
the puncture and a
compressor to generate the required tyre pressure. The
kit will reliably seal punctures up to a size of about 4 mm caused by the
penetration of a foreign body into the tyre.
Note
● Seek professional assistance if the repair of a
tyre puncture is not possi-
ble with the sealing compound.
Wheel change
Preparation work
What you must do before changing a wheel.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible. Choose a location that is as
level as possible.
