Deactivation System - BMW Z4 sDrive30i Owner's Manual

Do not touch the individual components imme‐
diately after the system has been triggered; oth‐
erwise, there is the danger of burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
your service center or a workshop that has the
necessary authorization for handling explosives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or un‐
desired triggering of the airbag, either of which
could result in injury.◀
Warning notices and information about the air‐
bags can also be found on the sun visors.
Automatic deactivation of the
passenger airbags
The system determines whether the front pas‐
senger seat is occupied by measuring the re‐
sistance of the human body. Front, knee and
side airbags on the passenger side are activated
or deactivated accordingly.
Passenger feet in the footwell
Make sure that the front passenger keeps
his or her feet in the footwell; otherwise, the front
passenger airbags may not function properly.◀
The indicator lamp above the interior rearview
mirror shows the current status of the passen‐
ger airbags, deactivated or activated, refer to
Status of passenger airbags below.
Follow the safety and operating instruc‐
tions
Before transporting a child on the passenger
seat, read the safety and operating instructions
under Transporting children safely, refer to
page 48.◀
Malfunction of the automatic

deactivation system

The front, knee and side airbags can also be de‐
activated by adolescents and adults sitting in
certain positions; the indicator lamp for the pas‐
senger airbags comes on. In this case, change
the sitting position so that the front passenger
airbags are activated and the indicator lamp
goes out. If the desired airbag status cannot be

achieved by changing the sitting position, do not
transport the passenger in the vehicle.
To make sure that occupation of the seat cush‐
ion can be detected correctly:
▷ Do not attach seat covers, seat cushion pad‐
ding, ball mats or other items to the passen‐
ger seat unless they are specifically recom‐
mended by BMW.
▷ Do not place objects under the seat that
could press against the seat from below.
Status of passenger airbags
The indicator lamp for the passenger airbags
shows the functional status of the passenger's
front, knee and side airbags in accordance with
whether and how the passenger seat is occu‐
pied. The indicator lamp shows whether the
passenger airbags are activated or deactivated.
▷ The indicator lamp lights up when a child
who is properly seated in a child restraint
system intended for that purpose is de‐
tected on the seat or the seat is empty. The
front, knee and side airbags for the passen‐
ger 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 instal‐
ling 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 air‐
bags are not activated.
▷ The indicator lamp does not light up when,
for example, a person of sufficient size and
in a correct sitting position is detected on
the seat. The front, knee and passenger air‐
bags for the passenger are activated.
