WARNING (continued )
• Seat covers can prevent the Advanced Airbag System from
recognizing child restraints or occupants on the front passenger
seat and prevent the side airbag in the seat backrest from
deploying properly.
• Never use cushions, pillows, blankets or similar items on the
front passenger seat. The additional padding will prevent the
weight-sensing mat in the seat from accurately registering the
child restraint or person on the seat and prevent the Advanced
Airbag System from functioning properly .
• If you must use a child restraint on the front passenger seat
and the child restraint manufa cturer's instructions require the use
of a towel , foam cushion or something else to properly position
the child restraint, make certain that the PASSENGER AIR BAG OFF
light comes on and stays on whenever the child restraint is
installed on the front passenger seat.
• If the PASSENGER AIR BAG OFF light does not come on and stay
on , immediately install child restraint in a rear seating position
and have the airbag system inspected by your Audi dealer. •

the pr otection offe red by t he front t hree-point safety bel t s with
pretens ioners and load li miters and the adj ustable head restraints
to help reduce the risk of in j ury in a wide range of accident and
crash situati on s. Be sure to read t he impo rta nt inf o r matio n abou t
safety and heed the WARNI NGS in th is chapter.
Dep loym ent of th e Adva nce d Ai rb ag System and the activati on of
th e safety be lt pretension ers depend on the decel eration measur ed
by the crash sens o rs and regis t ered by th e electr o nic control un it .
