ing situations, and driver intervention may be
necessary:▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷When detecting poorly-lit road users such
as pedestrians, cyclists, horseback riders
and wagons; when driving close to train or
ship traffic; and at animal crossings.▷In tight curves, on hilltops or in depressions,

Automatic deactivation of the front-
seat passenger airbags
The concept
The system reads if the front passenger seat is
occupied by measuring the human body's re‐
sistance.
Front, knee and side airbag on the front pas‐
senger's side are either activated or deacti‐
vated.
Information Before transporting a child on the front passen‐
ger seat, refer to the safety notes and instruc‐
tions for children on the front passenger seat,
see Children.
WARNING
To ensure the front-seat passenger airbag
function, it must be detected, whether a person
occupies the front passenger seat. The entire
seat cushion area must be used for this pur‐ pose. There is a risk of injury or danger to life.
Make sure that the front passenger keeps his or
her feet in the floor area. ◀
Malfunction of the automatic
deactivation system
When transporting older children and adults,
the front-seat passenger airbags may be deac‐
tivated in certain sitting positions. In this case,
the indicator lamp for the front-seat passenger
airbags lights up.
In this case, change the sitting position so that
the front-seat passenger airbags are activated
and the indicator lamp goes out.
If it is not possible to activate the airbags, have
the person sit in the rear.
To enable correct recognition of the occupied
seat cushion.▷Do not attach covers, cushions, ball mats or
other items to the front passenger seat un‐
less they are specifically determined to be
safe for use on the front passenger seat.▷Do not place any electronic devices on the
passenger seat if a child restraint system is
to be installed on it.▷Do not place objects under the seat that
could press against the seat from below.▷No moisture in or on the seat.
Indicator lamp for the front-seat
passenger airbags
The indicator lamp for the front-seat passenger
airbags indicates the operating state of the
