Strength of the driver's and front
passenger airbag
General information
The power that triggers the driver's/front passen‐
ger airbags depends on the position of the driv‐
er's/front passenger seat.
To maintain the accuracy of this function over
the long term, calibrate the front seats as soon as
a respective message appears on the Control
Display.
Calibrating the front seats
Warning
There is a risk of jamming when moving the
seats. There is a risk of injury or risk of damage
to property. Make sure that the area of move‐
ment of the seat is clear prior to any adjust‐
ment.
A corresponding message appears on the Con‐
trol Display.
1. Press the switch and move the respective
seat all the way forward, until it stops.
2. Press the switch forward again. The seat still
moves forward slightly.
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.
