Vehicle care and maintenance
Running gear settings : an incorrectly positioned running gear increases the
wear of tyres and affects your safety while driving. If tyres wear too quickly,
have the wheel alignment checked at a specialised workshop.
WARNING
If you notice unusual vibration or the car pulls to one side while driving,
this may indicate that one of the tyres is damaged.
● Reduce speed immediately and stop, while observing the highway
code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or wheels. Request qualified as-
sistance immediately.
● If there is no visible exterior damage, drive slowly and carefully to the
nearest specialised workshop and have the vehicle checked.
Spare wheel or temporary spare wheel*

●
Open the rear lid and lift the luggage compartment shelf ⇒ page 98.
● If necessary, remove the luggage compartment variable floor ⇒ page 98.
● Lift up the carpet from the recess and remove it from the luggage com-
partment.
● If necessary, take out the vehicle tool kit with the container.
● Completely remove the hand controlled wheel from the centre of the
spare wheel ⇒ Fig. 126 by turning it in an anticlockwise direction, and take
out the spare wheel.
Storing the replaced wheel
● Pull back the carpet.
● With the wheel rim facing downwards, situate the replaced wheel in the
spare wheel well so that the wheel rim central hole coincides with the open-
ing.
● Turn the hand controlled wheel with the shank screwed clockwise until
the replaced wheel is secured.
● If necessary, store the vehicle tool in the container, inside the luggage
compartment.
● Replace the carpet on the luggage compartment floor.
● Lower the rear shelf.
● Close the rear lid.
If the spare wheel is different to the rest of the vehicle tyres
If the spare tyre is not the same as the tyres that are mounted on the vehicle
- for example with winter tyres or the temporary spare wheel - you should
only use the spare tyre for a short period of time and drive with extra care
⇒
.
Refit the normal road wheel as soon as possible.
Please observe driving advice:
