Airbag system operational
The airbag warning lamp in the instrument
cluster indicates the operational readiness
of the entire airbag system and the safety
belt tensioners as of ignition key position 1.
The warning lamp goes out after a few sec-
onds.
Airbag system malfunction
Have the airbag system checked
immediately if a malfunction occurs,
as otherwise there is a danger of the sys-
tem not responding in the expected man-
ner to an impact occurring within its normal
response range.
<
There is a malfunction in the airbag
system when:
> The warning lamp does not light up as
of ignition key position 1
> The warning lamp remains on continu-
ously
> The warning lamp lights up while the
vehicle is being driven.

Rollover protection system
The rollover protection system is automati-
cally activated in the event of an accident
or a critical driving situation, extreme incli-
nation on the longitudinal or transverse
axis, or loss of ground contact. The rollover
bars located behind the rear head
restraints move out within fractions of a
second.
As a supplement to the rollover bar inte-
grated in the windshield frame, the rollover
protection system ensures that all vehicle
occupants have the necessary headroom.
Always keep the path of movement of
the rollover protection system clear.
In less severe accidents, you are protected
by the fastened safety belt and, depending
on the severity of the accident, the belt ten-
sioner and the multistage airbag restraint
system.

Lowering
If the protection function was not required
after automatic activation, the rollover pro-
tection system can be lowered again.
No tools are necessary for this purpose.
1. Press the release backwards and hold
in that position
2. Press the rollover bar halfway down
from above
3. Let go of the release
4. Press the rollover bar down until it
snaps into place
5. Use the same procedure for the second
rollover bar.
Have the rollover protection system
checked after unexpected triggering.
