Wheels and tiresVehicle features and op‐
tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Tire inflation pressure Safety informationThe tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the tire inflation pressure
WARNING
A tire with low or missing tire inflation
pressure impacts handling, such as steering
and braking response. There is risk of an acci‐
dent. Regularly check the tire inflation pressure,
and correct it as needed, e.g., twice a month and before a long trip. ◀
Tires have a natural, consistent loss of tire infla‐ tion pressure.
Tires heat up while driving, and the tire inflation
pressure increases along with the tire's temper‐
ature. The tire inflation pressure specifications
relate to cold tires or tires with the ambient
temperature.
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours.
The displays of inflation devices may under-
read by up to 0.1 bar.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire Moni‐
tor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.▷Reinitialize the Flat Tire Monitor.▷Reinitialize the Tire Pressure Monitor.
Pressure specifications
The tire inflation pressure table, refer to
page 187, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. The tire inflation pres‐
sure values apply to tire sizes approved by the
manufacturer 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.
Tire inflation pressures up to 100 mph/
160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer
to page 187, and adjust as necessary.
