Audi Q3: Engine compartment

General information

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 vehicle's engine compartment is a dangerous area.

Explanation of warning symbols:

   Observe all warnings - there is a risk for injury!

  Hot motor components! Rotating parts!

  The radiator fan can switch on at any time!

  High voltage! Switch off the engine before coming into contact with any ignition system components!

The catalytic converter can be damaged if the oil level is too high!

  Hot coolant - there is a risk of scalding!

  Always follow the instructions in the operating manual.

WARNING

  • Turn the engine off.
  • Switch the ignition off.
  • Set the parking brake.
  • Select the "P" (Park) selector lever position.
    Allow the engine to cool.
  • 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.
  • Never reach into the radiator fan. The fan is temperature-controlled and can turn on suddenly, even when the ignition is switched off.
  • 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.
  • The cap on the coolant expansion tank must never be opened when the coolant is hot.
    The cooling system is under pressure. There is a risk of burns
  • To protect your face, hands, and arms from hot steam or coolant, cover the cap with a thick cloth when opening.
  • Do not remove the engine cover under any circumstances. This increases the risk of burns.
  • Due to the risk of electric shock, never touch the ignition cable or other components in the electronic high-voltage ignition system when the engine is running or is starting.
  • If a gear is engaged while the vehicle is stationary and the engine is running, do not press the accelerator pedal inadvertently.
    Pressing the accelerator pedal will cause the vehicle to move, and this could result in an accident.
  • If inspections or repairs must be performed while the engine is running, moving components (such as the ribbed belt, generator, and radiator fan) pose an additional risk.
    • Set the parking brake first and select the "p" (Park) selector lever position.
    • Always make sure that no parts of the body, jewelry, ties, loose clothing, and long hair can be caught in moving engine components. Before any work, always remove any jewelry and/or ties, tie back long hair, and make sure all clothing fits close to the body to reduce the risk of anything becoming caught in engine components.
  • 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.
  • Limit your exposure to exhaust and chemicals to as short a time as possible.

WARNING

California Proposition 65 Warning:

  • Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the State of California to cause cancer and birth defects and reproductive harm. In addition, certain fluids contained in vehicles and certain products of component wear contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
  • Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harms. Wash hands after handling.

Note

When filling fluids, be sure not to add any fluids to the wrong reservoirs. Otherwise severe malfunctions and engine damage will occur.

For the sake of the environment

You should regularly check the ground under your vehicle in order to detect leaks quickly. If there are visible spots from oil or other fluids, bring your vehicle to an authorized Audi dealer or authorized Audi Service Facility to be checked.
