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, 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 observed.
Tire inflation pressure
General information
The tire characteristics and tire inflation
pressure 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 accident. Regularly check the tire
inflation pressure, and correct it as
needed, for instance twice a month and be-
fore a long trip.
Tire inflation pressure
specifications
In the tire inflation pressure table
The tire inflation pressure table, refer to
page 262, contains all tire inflation pres-
sure specifications for the specified tire
sizes at the ambient temperature. The tire
inflation pressure values apply to tire sizes
approved by the manufacturer of the vehicle
for the vehicle type.
To identify the correct tire inflation pres-
sure, 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 infla-
tion pressure increases with the tire tem-
perature.
Tires have a natural, consistent loss of tire
inflation 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 tempera-
ture 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.
