You can find information on the tyre pressure:
– on the tyre pressure plate in the front left door
aperture.
– In the Technical Data chapter in this
Driver’s Manual:
Please observe the chapter “TYRE
PRESSURES, COLD” on Page 326.
These values are for cold tyres (20 °C).
f
Check the tyre pressure at least every
2 weeks. Always check when tyres are cold.
f
On vehicles with Tyre Pressure Monitoring:
Please observe the chapter “SETTING TYRE
PRESSURE MONITORING” on Page 120.
When tyres are warm, the tyre pressure is
increased.
f
Never let air out of hot tyres. This could cause
the tyre pressure to fall below the prescribed
value.
Valve caps protect the valve from dust and dirt,
and thus from leakage.
f Always screw caps down tightly.
f Replace missing caps immediately.
Insufficient tyre pressure can cause tyres to
overheat and thus be damaged – even invisibly.
Hidden tyre damage is not eliminated by subse-
quently correcting the tyre pressure.
Tyre damage
Cleaning with high-pressure cleaners can damage
the tyres.
f
For further information on cleaning with high-
pressure cleaners:
Please observe the chapter “HIGH-PRESSURE
CLEANING UNITS” on Page 251.

Warning!
Risk of accident due to hidden tyre damage.
Tyres may burst, especially at high speeds.
f Check tyres including the sidewalls regularly
for foreign bodies, nicks, cuts, cracks and
bulges.
f Cross kerb edges slowly and at right angles if
possible.
Avoid driving over steep or sharp kerbs.
f In cases of doubt, have the wheel (particularly
the inner side) checked by an expert.
In the case of the following tyre damage, the tyre
must be replaced for safety reasons:
– Tyre damage where the possibility of a ply
fracture cannot be ruled out.
– If the tyre has been thermally and mechanically
overloaded following a loss of pressure or
other previous damage.
