Spare wheel
When replacing tyres on the vehicle, you
can use the spare wheel as a road wheel if:
it is less than six years old
the wheel and tyre are of the same type
as the road wheels
G
Risk of accident
If the spare wheel is more than six years old
or is of a different design to the road wheels,
have the spare wheel replaced with a new
wheel at the nearest qualified specialist
workshop, e.g. a Mercedes-Benz Service
Centre.
Never drive the vehicle with more than one
spare wheel fitted.
On vehicles with different tyre dimensions
on the front and rear axles: the wheel and
tyre sizes of the spare wheel and the normal
wheel are different. If you are using the
spare wheel, the handling characteristics
are affected.
Do not exceed a maximum speed of
80 km/h.
