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 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 as needed, even on the

compact tire: at least twice a month and before
starting long trips. If you fail to observe this pre-
caution you may be driving on tires with incor-
rect tire pressures, a condition that can not only
compromise your vehicle's driving stability, but
also lead to tire damage and the risk of an acci-
dent. Do not drive with deflated, i.e. flat tires,
except run-flat tires. A flat tire will seriously
impair your vehicle's handling and braking
response. Attempts to drive on a flat tire can
lead to loss of control over the vehicle.

After correcting the inflation pressure(s),
always reinitialize the Flat Tire Monitor,

refer to page

Pressure specifications for factory-
installed tires

The inflation pressures for your standard tires at
ambient temperature can be found on the door
post when you open the driver's door.

Pressure specifications for other tire
sizes

The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.

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

the specifications for the corresponding tire
size.

Tire size

The inflation pressures apply to the tire sizes
approved and tire brands recommended by
