Vehicle features and options
This chapter describes all standard, country-spe‐
cific and optional features offered with the series.
It also describes features that are not necessarily
available in your vehicle, for instance, 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 ob‐
served.
The tire inflation pressure table, refer to
page 207, 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.
Tire inflation pressure
Checking the tire inflation pressure
General information
Tires heat up while driving. The tire inflation
pressure increases with the tire temperature.
General information
The tire inflation pressure and tire characteristics
influence the following:
▷ The service life of the tires.
▷ Road safety.
Tires have a natural, consistent loss of tire infla‐
tion pressure.
▷ Driving comfort.
▷ Driving dynamics.
▷ Fuel consumption.
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.
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 accident. Regularly
check the tire inflation pressure, and correct it
as needed, for instance twice a month and be‐
fore a long trip.
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.
