Tyres - air pressure
Tyres can have different air pressures which
are measured in bar.
Check the air pressure in the tyres
The tyre pressures must be checked every
month.
•
Tyre pressure for the car's recommended
tyre dimension
•
2
ECO pressure
NOTE
•
Check the tyre pressure when the
tyres are cold. "Cold tyres" means that
the tyres are at the same temperature
as the outdoor temperature. The tyres
will heat up and the tyre pressures will
increase after driving for a few kilome-
tres.
•
Tyre pressures which are too low will
increase fuel consumption, reduce tyre
service life and impair the car's han-
dling. Driving with tyre pressures
which are too low may lead to the
tyres overheating and sustaining dam-
age. Tyre pressures affect ride com-
fort, road noise and steering.
•
Tyre pressure decreases over time,
this is a natural phenomenon. Tyre
pressure also varies depending on
ambient temperature.
ECO pressure results in improved fuel economy.

Tyre pressure label
The tyre pressure label on the driver's side
door pillar (between frame and rear door)
shows which pressures the tyres should have
at different loads and speed conditions. This
is also specified in the tyre pressure table,
see Tyres - approved tyre pressures (p. 407).
Fuel economy, ECO pressure
In order to obtain optimum fuel economy at
speeds below 160 km/h an ECO pressure is
recommended (applies to both full and light
load), see Tyres - approved tyre pressures (p.
407).
