Audi Q7: Emissions control system
General information
WARNING
The temperature of the exhaust system is high, both when driving and after stopping the engine.
- Never touch the exhaust tail pipes once they have become hot. This could result in burns.
- Do not park your vehicle over flammable materials such as grass or leaves because the high temperature of the emissions system could start a fire.
- Do not apply underbody protectant in the exhaust system area, because this increases the risk of fire.

The vehicle may only be driven with unleaded gasoline, or the catalytic converter will be destroyed.
Never drive until the tank is completely empty.
