Wheels and tires
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.
Tire inflation pressure
General information
The tire characteristics and tire inflation pres‐
sure influence the following:
▷ The service life of the tires.
▷ Road safety.
▷ Driving comfort.
▷ 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 response. There is a risk of an acci‐
dent. Regularly check the tire inflation pres‐
sure, and correct it as needed, for instance
twice a month and before a long trip.◀
Tire inflation pressure specifications
In the tire inflation pressure table
The tire inflation pressure table, refer to
page 233, 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.
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 in‐
flation 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
ambient 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.
Also check the tire inflation pressure of the
emergency wheel in the cargo area regularly,
and correct it as needed.
1.
Determine, refer to page 232, the intended
tire inflation pressure levels for the
mounted tires.
2. Check the tire inflation pressure in all four
tires, using a pressure gage, for example.
