WARNING Risk of accident due tothe
specified tyre pressure not being ach‐
ie ved
If th e specified tyre pressure is not achie ved
af te r a brief drive, the tyre is too badly dam‐
aged. The tyre sealant cannot repair the tyre
in this ins tance.
Dama ged tyres and a tyre pressure that is
to o low can significantly impair braking and
handling characteristics. 0007
Do not drive on. 0007

Cor rect the tyre pressure if it is still at least
13 0 kPa (1.3 bar/19 psi). See the tyre pres‐
sure table on the fuel filler flap forva lues. 0007
Toincrease the ty repressure: switch on

Ifyo u are unable torectify the damage,
conta ct aqualified specialist workshop. Information on
there commended tyre pressure
fo rth eve hicle's factor y-fitted tyres can be found
on the tyre pressure table on the inside of the
fuel filler flap (0013 page 450).
Use a suitable pressure gauge tocheck the tyre
pressure. The outer appearance of a tyre does
not permit any reliable conclusion about the tyre
pressure.
Ve hicles with a tyre pressure monitoring sys‐
te m: you can also check the tyre pressure using
th e on-board computer.
Only cor rect tyre pressures when the tyres are
cold. Conditions for cold tyres:
R The vehicle has been par ked with the tyres
out of direct sunlight for at least th ree hours.
R The vehicle has tr avelled less than 1.6 km.
A rise in the tyre temp erature of 10°C increases
th e tyre pressure byappr ox.10 kPa(0.1 bar/ 1.
5 psi). Take this into account when checking
th e tyre pressure of warm tyres.
