Tyre pressure
G021830
The tyre pressure decal 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
page 388.

NOTE
Temperature differences change the
tyre pressure.
Fuel economy, ECO pressure
At speeds under 160 km/h, the general tyre
pressure is recommended (applies for both full
load and light load) in order to obtain optimum
fuel economy.
Checking the tyre pressure
The tyre pressures must be checked every
month.
Check tyre pressures on cold tyres. "Cold
tyres" means the tyres are the same tempera-
ture as the ambient temperature. After several
kilometres of driving, the tyres warm up and the
pressure increases.
Inadequate tyre pressure increases fuel con-
sumption, shortens tyre lifespan and impairs
the car's roadholding. Driving on tyres with tyre
pressure that is too low could result in the tyres
overheating and being damaged. Tyre pres-
sure affects travelling comfort, road noise and
steering characteristics.
NOTE
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.
