Underinflated or overinflated tires
Underinflation
G WARNING
Tires with pressure that is too low can over-
heat and burst as a consequence. In addition,
they also suffer from excessive and/or irreg-
ular wear, which can severely impair the brak-
ing properties and the driving characteristics.
There is a risk of an accident.
Avoid tire pressures that are too low in all the
tires, including the spare wheel.
Underinflated tires may:
wear quickly and unevenly
R
have an adverse effect on fuel consumption
R
overheat, leading to tire defects
R
have an adverse effect on handling charac-
R
teristics
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:
have an adverse effect on handling charac-
R
teristics
wear quickly and unevenly
R
be more susceptible to damage
R
have an adverse effect on ride comfort
R
increase the braking distance

Maximum tire pressures
Never exceed the maximum permissible tire
inflation pressure. Always observe the rec-
ommended tire pressure for your vehicle
when adjusting the tire pressure
( page 317).

Checking the tire pressures
Important safety notes
Observe the "Tire pressure information" sec-
tion ( page 317).

Information on air pressure for the tires on
your vehicle can be found:
on the vehicle's Tire and Loading Informa-

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 with
