Safety precautions

If special testing equipment is required during test drive, note the following: 

WARNING:
  • When driving or riding in an airbag-equipped vehicle, NEVER hold the scan tool or other test equipment in your hands or lap while in motion. Objects between you and the airbag increase the risk of injury in an accident.
  • During a road test in an airbag-equipped vehicle, test equipment must always be fastened to and operated from the rear seat by a second technician.

To reduce the risk of personal injury and/or damage of electric and electronic components, always observe the following: 

CAUTION:
  • Always switch ignition off before connecting or disconnecting test/measurement tools.
  • It is possible that the control module will recognize a malfunction and store a DTC during some tests. After completing all tests and repairs, DTC memory should therefore be checked and erased if necessary.
  • Always switch ignition off before disconnecting or connecting battery. Failure to do so may damage a control module.
  • On vehicles equipped with Audi Telematics by OnStar(R), switch-off the emergency (back-up) battery for the Telematic/Telephone Control Module prior to disconnecting battery. See EMERGENCY (BACK-UP) BATTERY, SWITCH ON/OFF, RESET TIME REGISTER  .
