G
The air bags or Emergency Tensioning Devices may either be trig-
gered unintentionally or, in the event of an accident, may not be
triggered.
There is an increased risk of injury.
Drive on carefully.
X
Have the restraint system checked at a qualified specialist
X
workshop immediately.
For further information about the restraint system, see
( page 40).
Y
RBS (Recuperative Brake System) is unavailable due to a malfunc-
tion.
G WARNING
The braking performance of the electric motor using recuperative
braking may be either reduced or not effective. If you do not make
an additional effort to apply the brake yourself, the braking effect
may not be sufficient. If necessary, counteract the reduced regen-
erative braking effect by applying the brake yourself.
The brake system continues to function normally, but without the
functions listed above. The front and rear wheels could therefore
lock if you brake hard, for example.
Braking efficiency may be impaired.
Drive on taking extra care.
X
Visit a qualified specialist workshop.

Possible causes/consequences and M M Solutions
