Indicator lamp for the front passenger
airbags
The indicator lamp for the front passenger air‐
bags indicates the operating state of the front
passenger airbags.
The lamp indicates whether the airbags are ac‐
tivated or deactivated.
▷ The indicator lamp lights up
when a child in a child re‐
straint fixing system in‐
tended for the purpose is
properly detected on the
seat. The airbags on the front
passenger side are not acti‐
vated.
▷ The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient size is detected on the seat. The
airbags on the front passenger side are ac‐
tivated.
▷ The indicator lamp does not light up when
the seat is empty. However, the airbags on
the front passenger side are not activated.
Most child seats are detected by the system,
Especially the child seats required by NHTSA at
the time that the vehicle was manufactured.
After installing a child seat, make sure that the
indicator lamp for the front passenger airbags
lights up. This indicates that the child seat has
been detected and the front passenger airbags
are not activated.
Operational readiness of airbag system
In the radio ready state and beyond, re‐
fer to page 54, the warning lamp lights
up briefly to indicate that the entire air‐
bag system and the belt tensioners are opera‐
tional.
Airbag system malfunction
▷ Warning lamp does not light up in the radio
ready state.
▷ Warning lamp remains permanently on.
Have the airbag system checked without
delay if there is a malfunction
In the event of a malfunction in the airbag sys‐
tem, have it checked without delay; otherwise,
there is the risk that the system will not func‐
tion as intended even if a sufficiently severe ac‐
cident occurs.◀
FTM Flat Tire Monitor
The concept
The system does not measure the actual infla‐
tion pressure in the tires.
The system detects a pressure loss in a tire by
comparing the rotational speeds of the individ‐
ual wheels while moving.
In the event of a pressure loss, the diameter
and therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
reported as a flat tire.
