at ambient temperature. The tire inflation pres-
sure specifications apply to the tire sizes ap-
proved by the vehicle manufacturer for the cor-
responding vehicle types.
Vehicle features and options
This chapter describes model-specific equip-
ment, systems, and functions that are currently
available, or may become available in the fu-
ture, even if they are not present in the vehicle.
To identify the correct tire inflation pressure,
please note the following:
▷
▷
Tire sizes of the vehicle.
Additional information:
Maximum speed for driving.
Vehicle equipment, refer to page 8.
On the control display
Tire pressure
The current tire inflation pressure values and
the intended tire inflation pressure values for
the mounted tires can be displayed on the con-
trol display.
General information
The tire condition and tire pressure influence
the following:
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 service life of the tires.
Driving safety.
The current tire inflation pressure value is lo-
cated on each tire.
Driving comfort.
Electrical consumption.
The reference tire inflation pressure value is
located in the lower area of the control display.
Safety information
Checking the tire pressure
Warning
General information
The tires heat up while driving. The tire pres-
sure increases with the tire temperature.
A tire with too little or no tire inflation pres-
sure 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, and property damage. Regularly check
the tire inflation pressure, and correct it as
needed, for instance twice a month and be-
fore a long trip.
Tires have a natural, consistent tire pressure
loss.
The displays of inflation devices may under-
read by up to 0.1 bar/2 psi.
Checking via tire inflation pressure
specifications in tire pressure table
1. Determine the intended tire inflation pres-
sure levels for the mounted tires.

2. Check the tire inflation pressure in all four
tires, using a pressure gage, for example.
In the tire pressure table
The tire pressure table contains all tire infla-
tion pressure specifications for given tire sizes

pressure values on the control display, reset
the Tire Pressure Monitor (TPM).
If equipped with a flat tire monitor, reinitialize
the flat tire monitor.
4. Make sure that all valve caps are screwed
onto the tire valves.
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, follow the tire infla-
tion pressure specifications in the tire pressure
table and adjust as necessary.
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.:
▷
A distance traveled of max. 1.25 miles/2 km
has not been exceeded.
▷
If the vehicle has not moved again for at
least two hours after a trip.
If equipped with an emergency wheel: check
the tire pressure of the emergency wheel in the
cargo area regularly and correct if necessary.
Checking using the tire inflation
pressure specifications on the control
display
The tire inflation pressure specifications can
also be found on the tire pressure label on the
driver's door pillar.

When driving at speeds greater than
100 mph/160 km/h, incorrect tire pressures
can negatively affect vehicle handling, e.g.,
safety or comfort while driving. The tires can
become damaged, which may cause an ac-
cident. There is a risk of accident, injury,
and property damage. To drive at maximum
speeds, note the specified tire pressure for
driving above 100 mph/160 km/h in the tire
inflation pressure table, and adjust as neces-
sary.

Maximum tire load
Maximum tire load is the maximum permissi-
ble weight for which the tire is approved.
Production date
You can find the tire production date on the tire
sidewall.
Locate the maximum tire load on the tire
sidewall and the Gross Axle Weight Rating –
GAWR – on the certification label on the driver
door B-pillar. Divide the tire load by 1.1. It must
be greater than one-half of the vehicle’s Gross
Axle Weight Rating – GAWR. Note, front vs.
rear GAWR and tire loads, respectively.
