Tire pressure
312
Avoid tire pressures that are too low in all the
tires, including the spare wheel.
Underinflated tires may:
overheat, leading to tire defects
R
have an adverse effect on handling charac-
R
teristics
wear quickly and unevenly
R
have an adverse effect on fuel consumption
R
Overinflation
G WARNING
Tires with excessively high pressure can burst
because they are damaged more easily by
road debris, potholes etc. In addition, they
also suffer from irregular wear, which can
severely impair the braking properties and the
driving characteristics. There is a risk of an
accident.
Avoid tire pressures that are too high in all the
tires, including the spare wheel.
Overinflated tires may:
increase the braking distance
R
have an adverse effect on handling charac-
R
teristics
wear quickly and unevenly
R
have an adverse effect on ride comfort
R
be more susceptible to damage

Maximum tire pressures
Example: maximum permissible tire pres-
:
sure
Never exceed the maximum permissible tire
inflation pressure. Always observe the rec-
ommended tire pressure for your vehicle
when adjusting the tire pressure
( page 325).

Checking the tire pressures
Important safety notes
Observe the notes on tire pressure
( page 309).

Checking tire pressures manually
To determine and set the correct tire pres-
sure, proceed as follows:
Remove the valve cap of the tire that is to
X
be checked.
Press the tire pressure gauge securely onto
X
the valve.
Read the tire pressure and compare it to
X
the recommended value on the Tire and
Loading Information placard on fuel filler
flap of your vehicle (
The tire pressure is too low: increase the
X
tire pressure to the recommended value.
The tire pressure is too high: press down
X
the metal pin in the valve using the tip of a
pen, for example.
Air is released from the tire.
Check the tire pressure again with the tire
X
pressure gauge.
Screw the valve cap onto the valve.

Repeat these steps for the other tires.
