Securing child safety
seats
Securing a child safety seat using a safety
belt
Safety belts for the rear seats and the front pas­
senger can be locked with the convertible locking
retractor to properly secure child safety seats .
The safety belts emergency locking retractors for
the rear seats safety belts and for the front pas­
senger's seat safety belt have a convertible lock­
ing retractor for child restraints. The safety belt
must be locked so that belt webbing cannot un­
reel. The retractor can be activated to lock the
safety belt and prevent the safety belt webbing
from loosening up during normal driving. A child
safety seat can only be properly installed when
144
the safety belt is locked so that the child and
child safety seat will stay in place.
Always remember : Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and younger,
should always ride in the back seat properly re­
strained for their age and size.
A WARNING
Improperly installed child safety seats in­
crease the risk of serious personal injury and
death in a collision .
-
-Always make sure that the safety belt re­
tractor is locked when installing a child
safety seat. An unlocked safety belt retrac­
tor cannot hold the child safety seat in place
during normal driving or in a crash.
- Always buckle the child safety seat firmly in
place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a collision.
- Always make sure that the rear seat back­
rest to which the center rear safety belt is
attached is securely latched whenever the
rear center safety belt is being used to se­
cure a child restraint.
-If the backrest is not securely latched, the
child and the child restraint will be thrown
forward together with the backrest and will strike parts of the vehicle interior. The child
can be seriously injured or killed .
- Never install rear-facing child safety seats
or infant carriers on the front passenger
seat. A child will be seriously injured and
can be killed when the passenger airbag in­
flates.

in your vehicle can result in injuries, chemi­
cal burns, accidents or burns. Because of
this, all work must be performed
only by an
authorized Audi dealer or authorized Audi
Service Facility.
- To reduce the risk of electric shock and in­
jury, never touch the following components when the engine is running or is being start­
ed:
- Ignition cable
- Other components in the electronic high-
voltage ignition system
- If you must check or perform work on the
