Service Centre. #
Switch off the tyre inflation compressor. #

The tyre pressure must now be at least
13 0 kPa (1.3 bar/19 psi). &
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

before embarking on a longer journey
R if operating conditions change, e.g. off-
ro ad driving #
Adjust the tyre pressure as necessar y.Driving wi
thtyre pressu rethat is too high or too
low can:
R Sho rten the service life of the tyres.
R Cause increased tyre damage.
R Adversely af fect handling characteristics and
th us driving saf ety, e.g. due toaquaplaning. &
WARNING Risk of accident from repea‐
te d tyre pressure drop
If th e tyre pressure drops repeatedl y,the
wheel, valve or tyre may be damaged.
Insuf ficient tyre pressure can cause the tyres
to bur st. #
Inspect the tyre for signs of fore ign
objects. #
Check whe ther the wheel or valve has a
leak. #
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 (→ page 386).
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 thre e 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 ba r,1.
5 psi). Take this into account when checking
th e tyre pressure of warm tyres.

cold tyres under various operating conditions,
i.e. loading and/or speed of theve hicle.

The sy stem checks the tyre pressure and the
tyre temp erature of the tyres fitted totheve hicle
by means of a tyre pressu resensor.
New tyre pressure sensors, e.g. in winter tyres,
are automatically taught-in thefirs t time they are
driven. The tyre pressure appears in
the multifunction
display (→ page 228).
If th ere is a subs tantial pressure loss or if the
tyre temp erature is excessive, a warning will be
given:

It is the driver's responsibility toset the tyre
