Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Do not attempt to remove the airbag retention
system from the vehicle. Never modify or
tamper with either the wiring or the individual
components in the airbag system. This cate-
gory includes the upholstery in the center of the
steering wheel, on the instrument panel, the
side trim panels on the doors and on the Coupe,
the roof pillars along with the sides of the head-
liner. Do not attempt to remove or dismantle the
steering wheel.
Do not touch the individual components
directly after the system has been triggered,
because there is a danger of burns.
If you note any indication of system malfunc-
tion, if you wish to have an airbag deactivated,
or if the airbag retention system is triggered in
response to an accident, you should always
entrust all inspection, repair and dismantling
operations to your BMW center. Unprofessional
attempts to service the system could lead to
failure in an emergency or undesired airbag
activation, either of which could result in per-
sonal injury.
<
Airbag warning information is also provided on
the sun visors.
Operational readiness of airbag system
From ignition key position 1 the warning lamp
lights up briefly, indicating the operational
readiness of the entire airbag system and the
belt tensioners.
Airbag system malfunction
> The warning lamp does not light up as of
ignition key position 1.
>
The warning lamp lights up continuously.
Have the airbag system checked immedi-
ately if a malfunction occurs, as otherwise
there is a danger of the system not responding
in the expected manner to an impact occurring
within its normal response range.

Rollover protection system
The rollover protection system is automatically
activated in the event of an accident or a critical
driving situation, extreme inclination on the lon-
gitudinal or transverse axis, or loss of ground
contact. The rollover bars located behind the
rear head restraints are deployed within frac-
tions of a second.
As a supplement to the rollover bar integrated
into the windshield frame, the rollover protec-
tion 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 tensioner and
the multistage airbag restraint system.
<
Lowering
If the protection function was not required after
automatic activation, the rollover protection
system can be lowered again. No tools are nec-
essary for this purpose.
1. Press the release backward and hold in that
position.
