Belt tensioner
Depending on the force of an impact, fastened
safety belts are tightened in an accident.
The belt tensioners are triggered by:
– Front, side and rear impacts of sufficient
severity.
– Vehicle rollover.
Note
The belt tensioner system can be triggered only
once; the system must be replaced afterward.
If there is a fault in the belt-tensioner system, the
airbag warning light lights up.
Work may be performed on the belt-tensioner
system only by an authorized Porsche dealer.
Smoke is released when the belt tensioners are
triggered. This does not indicate a fire in the
vehicle.
Safety Belt Warning System
An audio-visual warning system is interconnect-
ed with the driver's safety belt.
Every time the ignition is turned on, the gong will
sound for about 6 seconds to remind driver and
passenger to buckle up. In addition, the gong
will sound for approx. 90 seconds if the vehicle
speed exceeds 15 mph (24 km/h). The safety belt
warning light in the instrument panel and on-board

buckled up.
Inertia reel retractor
The combination lap/shoulder belt with inertia reel
locking mechanism adjusts automatically to your
size and movements as long as the pull on the belt
is slow.
Rapid deceleration during hard braking or a
collision locks the belt. The belt will also lock
when you drive up or down a steep hill or in a sharp
curve, otherwise, the shoulder belt will not inhibit
your upper body movement.
Fastening the safety belt
