Technician Safety Information

PLEASE READ THESE WARNINGS AND CAUTIONS before proceeding with maintenance and repair work.
- Disconnect the battery Ground strap whenever you work on the fuel system or the electrical system. Do not smoke or work near heaters or other fire hazards. Keep an approved fire extinguisher handy.
- Any time the battery has been disconnected it will be necessary to re-establish Basic Settings for the Engine Control Module and, on vehicles with automatic transmission, the Transmission Control Module, using the VAG 1551 Scan Tool.
- On cars equipped with anti-theft radios, make sure you know the correct radio activation code before disconnecting the battery or removing the radio. If the wrong code is entered into the radio when power is restored, that radio may lock up and be rendered inoperable, even if the correct code is then entered.
- 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 accidently activated and cause serious personal injury.
- When boost charging the battery, first remove the fuses for the Engine Control Module, Transmission Control Module, ABS Control Module, and the on-board computer. In cases where one or more of these components is not separately fused, disconnect the Control Module connector(s).
- 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.
