The tire sizes of the mounted tires can be
gathered from the tire inflation pressure de-
tails on the vehicle or directly on the tires.
The tire details do not need to be re-entered
when the tire pressure is corrected.
For summer and winter tires, the tire details
entered last are stored. After a tire or wheel
change, the settings of the tire sets used
last can be selected.
Configuring the tire settings
To enter information on equipped tires in
the tire settings, proceed as follows:
1. Go through the menu as follows:
Apps menu / "Vehicle" / "Vehicle
status" / "Tire Pressure Monitor" / "Tire
settings" / "Tire selection" / "Manual" /
"Tire type".
2. Select the tire size for the rear axle.
When using tires with special approval:
"Other tires"
Follow the instructions given in the
“Performing a reset” section.
3. Select the maximum speed to be driven.
4. "Save tire settings"
The measurement of the current tire infla-
tion pressure is started. The measurement
progress is displayed.
Status display
Current status
The status of the Tire Pressure Monitor,
e.g., whether this system is active, can be
shown on the Interaction Unit.
Go through the menu as follows: Apps
menu / "Vehicle" / "Vehicle status" / "Tire
Pressure Monitor".
The current status is displayed.
Current tire pressure
The current tire pressure is displayed for
each tire.
The current tire inflation pressures may
change while driving or depending on the
outside temperature.
Nominal pressure
The nominal pressure for the tires on the
front and rear axles is displayed.
The specified nominal pressures take the
influence of driving and outside tempera-
ture on the tire temperature into account.
The appropriate nominal pressure is always
displayed, independent of the weather situa-
tion, tire temperatures and travel times.
The displayed nominal pressure may change
and may differ from the tire inflation pres-
sure details on the door pillar of the driver's
door. The tire inflation pressure can thus
be corrected to the value of the displayed
target pressures.
The nominal pressure is immediately ad-
justed if the vehicle load state is changed
in the tire settings.
Tire conditions
General information
The tire condition and system status are
indicated by the wheel color and text on the
Tire Pressure Monitor on the Interaction
Unit.
Any existing messages may not be deleted
if the nominal pressure is not reached after
the tire inflation pressure is corrected.
All wheels green
On the Interaction Unit, each wheel illumi-
nates green in the Tire Pressure Monitor
when the system is active.
