Tireinflationpressure
Generalinformation
The tire characteristics and tire inflation presj
sure influence the following:'yThe service life of the tires.'yRoad safety.'yDriving comfort.'yFuel consumption.
Safetyinformation
WARNING
A tire with too little or no tire inflation
pressure may heat up significantly and sustain
damage. This will have a negative impact on aspects of handling, such as steering andbraking response. There is a risk of an accij
dent. Regularly check the tire inflation presj
sure, and correct it as needed, for instance
twice a month and before a long trip.'

3.Correct the tire inflation pressure if the curjrent tire inflation pressure value deviates
from the specified value.4.Check whether all valve caps are screwed onto the tire valves.

For run-flat tires: reinitialize run-flat tires.
For the Tire Pressure Monitor TPM: reset the
Tire Pressure Monitor TPM.

100mph/160km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer to page 232, and adjust as necessary.
These pressure values can also be found on
the tire inflation pressure label on the driver's
door pillar.
