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 and if necessary adjust tire
inflation pressures regularly, also on
the compact 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 driving 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 pressure
Only check tire inflation pressure when
the tires are cold. This means after a maxi-
mum 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 infla-
tion pressure increases.
After correcting the inflation pres-
sure(s), always reinitialize the Flat Tire
Monitor, refer to page

Inflation pressure 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 corre-
sponding tire size.<
