Safety precautions
Note the following points if test equipment is used during a road test:
WARNING:
- To avoid any risk of accident, observe the following precautions when using test instruments while road testing the vehicle:
Audi TT Coupe:
- Use only VAS 5051 or V.A.G 1551 to read measured value blocks. The tester must always be secured on the rear seat and operated from the rear seat by a second person.
- Due to the limited space, slide the front passenger's seat forward as far as it will go and (without pulling the release lever) incline the backrest as far forward as possible by turning the adjuster knob. Do not operate the release lever to tilt the backrest forward.
Audi TT Roadster:
- In the Audi TT Roadster, use only V.A.G 1552 and with the front passenger's airbag switched off.
- Disable the front passenger's airbag by means of the key-operated switch in the glove box.
- Switch on front passenger's airbag after testing has been completed.
