Tire inflation pressure
General information

influence the following:
▷
The service life of the tires.
▷
Road safety.
▷
Driving comfort.
▷
Driving dynamics.
▷
Fuel consumption.
Safety information
WARNING
A tire with too little or no tire inflation pressure
may heat up significantly and sustain damage.
This will have a negative impact on aspects of
handling, such as steering and braking re‐
sponse. There is a risk of an accident. Regularly
check the tire inflation pressure, and correct it
as needed, for instance twice a month and be‐
fore a long trip.
Tire inflation pressure
specifications
In the tire inflation pressure table
The tire inflation pressure table, refer to
page
, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. The tire inflation pressure
values apply to tire sizes approved by the manu‐
facturer of the vehicle for the vehicle type.
To identify the correct tire inflation pressure,
please note the following:
▷
Tire sizes of your vehicle.
▷
Maximum permitted driving speed.
Checking the tire inflation
pressure
General information
Tires heat up while driving. The tire inflation
pressure increases with the tire temperature.
Tires have a natural, consistent loss of tire infla‐
tion pressure.
The displays of inflation devices may under-read
by up to 0.1 bar/2 psi.
Checking using tire inflation
pressure specifications in the tire
inflation pressure table
The tire inflation pressure specifications in the
tire inflation pressure table only relate to cold
tires or tires at the same temperature as the am‐
bient temperature.
Only check the tire inflation pressure levels when
the tires are cold, i.e.:
▷
Driving range of max. 1.25 miles/2 km has not
been exceeded.
▷
If the vehicle has not moved again for at least
2 hours after a trip.
