Audi A4 2015 Repair Manual page 199

 When boost-charging the battery, first remove the fuses for the Engine Control Module (ECM),
the Transmission Control Module (TCM), the ABS control module, and the trip computer. In
cases where one or more of these components is not separately fused, disconnect the control
module connector(s).
 Some of the vehicles covered by this manual are equipped with a supplemental restraint
system (SRS), that automatically deploys an airbag in the event of a frontal impact. The airbag
is operated by an explosive device. Handled improperly or without adequate safeguards, it can
be accidentally activated and cause serious personal injury. To guard against personal injury
or airbag system failure, only trained Audi Service technicians should test, disassemble or
service the airbag system.
 Do not quick-charge the battery (for boost starting) for longer than one minute, and do not
exceed 16.5 volts at the battery with the boosting cables attached. Wait at least one minute
before boosting the battery a second time.
 Never use a test light to conduct electrical tests of the airbag system. The system must only
be tested by trained Audi Service technicians using the Audi Factory Approved Scan Tool (ST)
or an approved equivalent. The airbag unit must never be electrically tested while it is not
installed in the vehicle.
 Some aerosol tire inflators are highly flammable. Be extremely cautious when repairing a tire
that may have been inflated using an aerosol tire inflator. Keep sparks, open flame or other
sources of ignition away from the tire repair area. Inflate and deflate the tire at least four times
before breaking the bead from the rim. Completely remove the tire from the rim before
attempting any repair.
 When driving or riding in an airbag-equipped vehicle, never hold test equipment in your hands
or lap while the vehicle is in motion. Objects between you and the airbag can increase the risk
of injury in an accident.
