Tire inflation pressure

Information for your safety

It is not merely the tire's service life, but also
driving safety and driving comfort that largely
depend on the condition of the tires and the
maintenance of the specified tire pressure.

Checking tire pressures

Check the tire inflation pressures only when the
tires are cold. This means after a maximum driv-
ing distance of 1.25 miles/2 km or if the vehicle
has been parked for at least 2 hours. Warm tires
have higher inflation pressures.

Check tire inflation pressures regularly
and correct them if necessary: at least

every two weeks and before every extended
journey. Otherwise, incorrect tire pressures can
cause driving instability or tire damage, ulti-
mately resulting in accidents.

Reinitialize the Flat Tire Monitor after cor-
recting the tire inflation pressure. Refer to

page

Inflation pressures for original tires
