Vehicle 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 vehicle, e. g., due
to the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and
systems, the applicable laws and regulations
must be observed.
The tire inflation pressure specifications only
relate to cold tires or tires at the same temper‐
ature as the ambient temperature.
Tires heat up while driving. The tire inflation
pressure increases with the tire temperature.
The displays of inflation devices may under-
read by up to 0.1 bar/2 psi.
Tires have a natural, consistent loss of tire in‐
flation pressure.
Check whether all valve caps are screwed onto
the tire valves.
Tire inflation pressure
Also check the tire inflation pressure of the
emergency wheel in the cargo area regularly,
and correct it as needed.
General information
The tire characteristics and tire inflation pres‐
sure influence the following:
▷
▷
▷
▷
The service life of the tires.
Road safety.
After correcting the tire inflation
pressure
For run-flat tires: reinitialize run-flat tires.
Driving comfort.
For the Tire Pressure Monitor TPM: reset the
Tire Pressure Monitor TPM.
Fuel consumption.
Safety information
Tire inflation pressure specifications
WARNING
The tire inflation pressure table, refer to
page 221, 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.
A tire with low or missing tire inflation
pressure impacts handling, such as steering
and braking response. There is a risk of an ac‐
cident. Regularly check the tire inflation pres‐
sure, and correct it as needed, e.g., twice a
month and before a long trip.◀
To identify the correct tire inflation pressure,
please note the following:
Checking the tire inflation pressure
General information
Only check the tire inflation pressure when the
tires are cold, i.e.:
▷
▷
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
▷
Driving range of max. 1.25 miles/2 km has
not been exceeded.
