Page: 154 / 330

Warning
Improperly executed work can lead to failure,
malfunction or unintentional triggering of the
airbag system. In the case of a malfunction, the
airbag system might not trigger as intended de‐
spite the accident severity. There is a risk of in‐
juries or danger to life. Have the airbag system
checked, repaired, dismantled and scrapped by
a dealer’s service center or another qualified
service center or repair shop.
Display in the instrument cluster
When drive-ready state is switched on,
the warning light in the instrument clus‐
ter lights up briefly and thereby indicates
the function readiness of the entire airbag sys‐
tem and the belt tensioners.
Malfunction
▷ Warning light does not come on
when drive-ready state is switched
on.
▷ The warning light lights up continuously.
Have the system checked.
Strength of the driver's and
front-seat passenger airbag
The explosive power that activates driver's/front-
seat passenger airbags very much depends on
the positions of the driver'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.
Automatic deactivation of
the front-seat passenger
airbags
Concept
The system reads if the front passenger seat is
occupied by measuring the human body's resist‐
ance.
Front, knee, and side airbag on the front pas‐
senger's side are activated or deactivated.
General information
Before transporting a child on the front passen‐
ger seat, refer to the safety information and in‐
structions for children on the front passenger
seat, see Children.
