Audi A6 Typ 4G: Engine compartment

Working in the engine compartment

Special care is required if you are working in the engine compartment

For work in the engine compartment, such as checking and filling fluids, there is a risk of injury, scalding, accidents, and burns. For this reason, follow all the warnings and general safety precautions provided in the following information.

The engine compartment is a dangerous area on the vehicle. .

WARNING

• Turn the engine off.
• Switch the ignition off.
• Set the parking brake.
• Select the P selector lever position.
• Let the engine cool down.
• Never open the hood when there is steam or coolant escaping from the engine compartment, because there is a risk that you could be burned. Wait until no steam or coolant is escaping.
• Keep children away from the engine compartment.
• Never spill fluids on a hot engine. These fluids (such as the freeze protection contained in the coolant) can catch fire.
• Avoid short circuits in the electrical system.
• When working in the engine compartment, remember that the radiator fan can switch on even if the ignition is switched off, which increases the risk of personal injury.
• Never open the cap on the coolant expansion tank when the engine is warm. The cooling system is under pressure.
• To protect your face, hands, and arms from hot steam or coolant, cover the cap with a large cloth when opening.
• Do not remove the engine cover under any circumstances. This increases the risk of burns.
• If tests need to be performed with the engine running, there is additional danger due to moving components (such as the ribbed belt, alternator and radiator fan) and from the high voltage ignition system.
• Do not under any circumstances give gas inadvertently (for example, by hand from the engine compartment) if the vehicle is stationary but the engine is running and a gear is engaged. Otherwise, the vehicle will start to move immediately and this could result in an accident.
• Pay attention to the following warnings listed when work on the fuel system or on the electrical equipment is required.
  • Do not smoke.
  • Never work near open flames.
  • Always have a working fire extinguisher nearby
• All work on the battery or electrical system in your vehicle can result in injuries, chemical burns, accidents or burns. Because of this, all work must be performed only by an authorized Audi dealer or authorized Audi Service Facility.
• To reduce the risk of electric shock and injury, never touch the following components when the engine is running or is being started:
  • Ignition cable
  • Other components in the electronic high-voltage ignition system
• If you must check or perform work on the engine while it is running:
  • Set the parking brake and place the selector lever in the P (park) position first.
  • Always proceed with extreme caution so that clothing, jewelry or long hair do not become caught in the radiator fan, fan belt or other moving components or do not come into contact with hot components.

    Tie back long hair before beginning work and do not wear clothing that can hang down into the engine.

• Limit your exposure to exhaust and chemicals to as short a time as possible .
