Wheels and tiresVehicle features and options
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
systems.
Tire inflation pressure
Safety information
The 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
Check the tire inflation pressure regularly
Regularly check the tire inflation pres‐
sure, and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect tire pressures, a condition
that may not only compromise your vehicle's
driving stability, but also lead to tire damage
and the risk of an accident.◀
Tires have a natural, consistent loss of tire in‐
flation pressure.
Tires heat up while driving, and the tire infla‐
tion pressure increases along with the tire's
temperature. The tire inflation pressure speci‐
fications 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 1.45 psi/0.1 bar.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire
Monitor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.
Tire inflation pressure specifications
The tire inflation pressure table, refer to
page 203, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. Tire inflation pressure
specifications apply to approved tire sizes and
recommended tire brands. This information
can be obtained from your service center.
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 203, and adjust as necessary.
