senger airbags lights up. This indicates that the
child seat has been detected and the front pas‐
senger airbags are not activated.

Strength of the driver's and front

passenger airbag

The strength with which the driver's and front
passenger airbags are triggered depends on the
position of the driver's and front passenger
seats.
To maintain the accuracy of this function over
the long-term, calibrate the front seats when a
corresponding message appears on the Control
Display.

Calibrating the front seats

A corresponding message appears on the Con‐
trol Display.

1.

Move the respective seat forward all the
way.

2.

Move the respective seat forward again. It
moves forward briefly.

3.

Readjust the seat to the desired position.

The calibration procedure is completed when
the message on the Control Display disappears.
If the message continues to be displayed, repeat
the calibration.
If the message does not disappear after a repeat
calibration, have the system checked as soon as
possible.

Unobstructed area of movement
Ensure that the area of movement of the

seats is unobstructed to avoid personal injury or
damage to objects.◀

Tire Pressure Monitor TPM

The concept

The tire inflation pressure is measured in the
four mounted tires. The system notifies you if

there is a significant loss of pressure in one or
more tires.

Functional requirements

The system must have been reset when the in‐
flation pressure was correct; otherwise, reliable
signaling of a flat tire is not ensured. Always use
wheels with TPM electronics to ensure that the
system will operate properly. Reset the system
after each correction of the tire inflation pres‐
sure and after every tire or wheel change.

System limits

Sudden tire damage
Sudden serious tire damage caused by

external influences cannot be indicated in ad‐
vance.◀

The system does not operate correctly if it has
not been reset. For example, a flat tire may be
indicated despite correct tire inflation pres‐
sures.
The system is inactive and cannot indicate a flat
tire:

For a mounted wheel without TPM electron‐
ics.

When the TPM is disturbed by other sys‐
tems or devices with the same radio fre‐
quency.

Status display

The current status of the Tire Pressure Monitor
TPM can be displayed on the Control Display,
e.g., whether or not the TPM is active.

1.
