Tyre pressure

Recommended tyre pressure
The tyre pressure label on the driver's side door
pillar shows which pressures the tyres should
have at different load and speed conditions.

NOTE
Tyre pressure decreases over time, this is a
natural phenomenon. Tyre pressure also
varies depending on ambient temperature.
Even after several kilometres of driving, the
tyres warm up and the pressure increases. So
air must not be released if the pressure is
checked when the tyres are warm. While the
pressure must be increased if it is too low.
Inadequately inflated tyres increase fuel con-
sumption, shorten tyre lifespan and impair the
car's roadholding. Driving on tyres with tyre
pressure that is too low can also result in the
tyres overheating and disintegrating.
For information on the correct tyre pressure,
refer to the tyre pressure table. The specified
tyre pressures refer to "cold tyres". ("Cold
tyres" means the tyres are the same tempera-
ture as the ambient temperature.)
Fuel economy, ECO pressure
At speeds under 160 km/h the general tyre
pressure for maximum load is recommended
in order to obtain optimum fuel economy.
Tyre pressure affects travelling comfort, road
noise and steering characteristics.
DRIVe*
An important detail in connection with environ-
mentally-conscious driving is to use the right
type of tyres and to drive with the correct air
pressure inside them.
Dimensions
When fitting new tyres, the same type and
brand as the car was equipped with from the
factory are recommended - they are designed
for low fuel consumption.
The 195/65 R15 and 205/55 R16 dimensions
generally provide a slightly lower consumption
than wider variants.
Pressure
Inadequately inflated tyres increase fuel con-
sumption. For this reason, check the pressure
in the tyres regularly.
By using so-called ECO pressure
sumption is minimised. A certain impact on ride
comfort, road noise and steering characteris-
tics may be experienced, but this does not
affect safety.

pressure adjacent to the driver's door pillar.
