Tire inflation pressure
Information for your safety
It is not merely the tire's service life, but also
driving comfort and – to a great extent – driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
Checking tire inflation pressure
Only check tire inflation pressure when the tires
are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly
and correct it if necessary: at least every
two weeks and before beginning a longer trip. If
you fail to observe this precaution, you may be
driving on tires with incorrect tire pressures, a
condition that can not only compromise your
vehicle's stability, but also lead to tire damage
and the risk of an accident.

After correcting the inflation pressure(s),
always reinitialize the Flat Tire Monitor,
refer to page 84 . <
Pressure specifications for factory-
installed tires
The tire inflation pressures with the ambient
temperature are visible on the door pillar with
the driver's door open.
Pressure specifications for other tire
sizes
The tables below provide all the correct inflation

For correct identification of the right tire
inflation pressure for your tires, observe
