Regardless of the child restraint that you use, make sure that it has been certified to meet Safety Standards and has been certified by its manufacturer for use with an airbag. Always be sure that the child restraint is properly installed at one of the rear seating positions. If in exceptional circumstances you must use it on the front passenger seat, carefully read all of the information on child safety and Advanced Airbags and heed all of the applicable WARNINGS. Make certain that the child and child restraint are correctly recognized by the capacitive passenger detection system in the front passenger seat, that the front passenger airbag is turned off, and that the airbag status is always correctly signaled by the PASSENGER AIR BAG OFF light.
Many types and models of child restraints have been available over the years, new models are introduced regularly incorporating new and improved designs and older models are taken out of production. Child restraints are not standardized.
Child restraints of the same type typically have different weights and sizes and different "footprints", the size and shape of the bottom of the child restraint that sits on the seat, when they are installed on a vehicle seat. These differences make it virtually impossible to certify compliance with the requirements for advanced airbags with each and every child restraint that has ever been sold in the past or will be sold over the course of the useful life of your vehicle.
For this reason, the United States National Highway Traffic Safety Administration has published a list of specific type, makes and models of child restraints that must be used to certify compliance of the Advanced Airbag System in your vehicle with the suppression requirements of Federal Motor Vehicle Safety Standard 208. These child restraints are:
Subpart A - Car bed child restraints
Subpart B - Rear-facing child restraints
Subpart C - Forward-facing and convertible child restraints
WARNING
To reduce the risk of serious injury, make sure that the PASSENGER AIR BAG OFF light comes on and stays on whenever a child restraint is installed on the front passenger seat and the ignition is switched on.
Tips
The child seats listed in categories A to C have been statically tested by Audi only for the Advanced Airbag function.
