headrest BMW 640I CONVERTIBLE 2012 Owners Manual

Rollover protection system
The concept
The
rollover protection system is activated dur‐
ing an accident or a critical driving situation,
when there is extreme tilt with respect to the
longitudinal axis or when there is loss of ground
contact. The safety frames located behind the
rear headrests extend within fractions of a sec‐
ond.
In addition to the rollover bracket integrated in
the front windshield frame, the rollover protec‐
tion system guarantees the required head clear‐
ance of all vehicle occupants.
Maintaining movement space
Always keep the movement space of the
rollover protection system clear. Otherwise,
there may be damage or injuries when the roll‐
over protection system is triggered.◀
In less severe accidents, the secured safety belt
and, depending on the severity of the accident,
the belt tensioner and airbag restraint system
provide protection.
Triggered rollover protection system
After deployment or damage
After deployment of the rollover protec‐
tion system or in the event of damage, have the
system checked and replaced.
Have this work performed only by your service
center; otherwise, it cannot be ensured that this
safety feature will function properly.◀
Do not move convertible top
When the rollover protection system is ex‐
tended, do not move the convertible top. Oth‐
erwise, damages or injuries may result.◀
If the rollover protection system was not placed
under any stress after an automatic triggering, it
can be pushed back by hand, e.g. to close the
convertible top. Three people are necessary for
this. 1.
Push the lever to the side and hold it in this
position. 2.
Push down the safety frame.
3. Release lever.
4. Hold down the safety frame.
5. Proceed likewise with the second safety
frame.
6. Close the convertible top
In the event of malfunctions, deactivation
or after deployment
Only have the airbags checked, repaired or dis‐
mantled

and the system scrapped by your serv‐
ice center. Non-professional attempts to service
the system could lead to failure in an emergency
or undesired triggering of the airbag, either of
which could result in injury.◀
Malfunction
A Check Control message is displayed
when there is a malfunction.
Tire Pressure Monitor TPM*
The concept
The tire inflation pressure is measured in the
four mounted tires. The system notifies you if
there is a significant loss of pressure in one or
more tires.
Functional requirements
The system must have been reset when the in‐
flation pressure was correct; otherwise, reliable
signaling of a flat tire is not ensured. Always use
wheels with TPM electronics to ensure that the Seite 91
