Wheels and tires
Vehicle features and options
This chapter describes model-specific
equipment, systems, and functions that are
currently available, or may become available
in the future, even if they are not present in
the vehicle.
Additional information:
Vehicle equipment, refer to page 8.
Tire pressure
General information
The tire condition and tire pressure influ-
ence the following:
– Tire service life.
– Driving 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 accident, injury, or property dam-
age. Regularly check the tire inflation
pressure, and correct it as needed, for in-
stance twice a month and before a long
trip.
Tire pressure specifications
In the tire pressure table
The tire pressure table, refer to page 286,
contains all tire inflation pressure specifica-
tions for given tire sizes at ambient temper-
ature. The tire inflation pressure specifica-
tions apply to the tire sizes approved by the
vehicle manufacturer for the corresponding
vehicle types.
To identify the correct tire inflation pres-
sure, please note the following:
– Tire sizes of the vehicle.
– Maximum speed for driving.
On the Interaction Unit
Current tire pressures and nominal tire
pressures for fitted tires can be displayed
on the Interaction Unit.
To ensure that they are displayed correctly,
the tire sizes must be stored in the system
and must have been set for the mounted
tires.
The current tire inflation pressure value is
located on each tire.
The reference tire pressure is shown at the
bottom of the Interaction Unit.
Checking the tire pressure
General information
The tires heat up while driving. The tire
pressure increases with the tire tempera-
ture.
Check the tire pressure regularly and cor-
rect as necessary.
Tires have a natural, consistent tire pres-
sure loss. The displays of inflation devices
may under-read by up to 0.1 bar/2 psi.
