W WARNING ARNING Risk of accident due to repea-
ted pressure drop in the tyres
The wheels, valves or tyres could be damaged.
Too low a tyre pressure can lead to the tyres
bursting.

Information on the recommended tyre pressure
for the vehicle's factory- tted tyres can be found
on the tyre pressure table on the inside of the fuel

Use a suitable pressure gauge to check the tyre
pressure. The outer appearance of a tyre does not
permit any reliable conclusion about the tyre pres-
sure.
Only correct tyre pressures when the tyres are
cold. Conditions for cold tyres:
R
The vehicle has been parked with the tyres out
of direct sunlight for at least three hours.
R
The vehicle has travelled less than 1.6 km.
The vehicle's tyres heat up when driving. As the
temperature of the tyres increases, so too does
the tyre pressure.
