Front Airbags - Audi TTS Coupe 2015 Owner's Manual

Airbag system
of the airbag or belt tensioner systems are
scrapped.
- For safety reasons, the alternator and the
starter are both disconnected from the bat­
tery via a pyrotechnic circuit breaker in se­
vere accidents.
- Any repairs to the pyrotechnic circuit
breaker must always be performed by a
qualified workshop - risk of accident!
- The relevant safety requirements must be
observed when the vehicle or the circuit
breaker are scrapped.
When are the airbags triggered?
One or more airbag systems are triggered in se­
vere collisions, depending on the circumstances.
The airbag system is not triggered in minor colli­
sions, or in rear collisions, or if the car overturns.
In these situations, the occupants are protected
by wearing the seat belts.
Factors determining the triggering response
It is not possible to define the exact triggering
response of the airbag system in all possible sit­
uations, since the circumstances in different
types of accident will vary considerably. Impor­
tant factors include, for example, the nature
(hard or soft) of the object which the car hits, the
angle of impact, vehicle speed and so on.
Whether the airbags are triggered depends pri­
marily on the vehicle deceleration rate resulting
from the collision. By processing the signals from
the sensors located in the vehicle, the electronic
control unit is immediately able to evaluate the
severity of the collision and activate the restraint
systems accordingly. If the deceleration rate is
below the predefined reference value in the con­
trol unit the airbags will not be triggered, even
though the accident may cause extensive damage
to the car.

Note
The airbag may release a fine dust when it in­
flates. This is quite normal and does not
mean there is a fire in the vehicle.
