Wheels and tires
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 condi-
tion of the tires and the maintenance of the
specified tire pressure.
Check the tire inflation pressure regu-
larly and correct it if necessary,
including the spare wheel: 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.
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 vehi-
cle.

Checking inflation pressure
Only check tire inflation pressure when
the tires are cold. i.e. after a maximum of
2 hours' driving or when the vehicle has
been parked for at least 2 hours. When tires
are warm, the tire inflation pressure
increases.
After correcting the inflation pressure(s),
always reinitialize the Flat Tire Monitor,
refer to page
95 .
Inflation pressure for original tires
The inflation pressures for your standard
tires can be found on the door pillar when
you open the driver's door.
Inflation pressure for other tire sizes
The table below provides 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 corre-
sponding tire size.
