In the event of a fault in the airbag system, 
have it checked without delay; otherwise, 
there is the risk that the system will not function 
as intended even if a su fficiently severe acci-
dent occurs. <
Convertible: rollover 
protection system
The rollover protection  system is activated 
automatically in the event  of an accident, a crit-
ical driving situation, an extreme tilt in the car's 
longitudinal axis or upon loss of ground contact. 
The protection bars behind the rear head 
restraints deploy within  fractions of a second.
As a supplementary system to the reinforced 
windshield frame, the rollover protection sys-
tem ensures that the necessary headroom is 
maintained for all vehicle occupants. Always keep the area of movement of the 
rollover protection system clear.
In minor accidents, you are protected by the 
fastened safety belt and, depending on acci-
dent severity, by the sa fety belt tensioner and 
multi-phase airbag retention system. <
Resetting
If the rollover protection system was not 
impacted after being automatically activated, it 
can be reset by lowering  the protection bars to 
their original positions. This does not require 
tools.
1. Push the locking lever to one side and hold 
it there. 2.
Push the protection bar halfway down from 
above.
3. Release the locking lever.
4. Push the protection bar down until it snaps 
into place.
5. Repeat the procedure for the other protec-
tion bar.
Have the rollover protection system checked 
after an unexpected activation.
Never move the retrac table hardtop when 
the rollover protection system is in the 
activated position.
Do not make any modifica tions to the individual 
components of the rollover protection system 
or its cabling.
Work on the rollover protection system should 
be performed only by your BMW center.
Incorrectly performed work on the system may 
lead to system failure  or incorrect operation.
To check the system and ensure flawless long-
term operation, always observe the service 
intervals, refer to page 87.<
