Audi Q3: Ignition key

Applies to: vehicles with ignition lock

Starting the vehicle
Fig. 80 Steering column: ignition lock

Starting the engine

  • Press the brake pedal.
  • Insert the ignition key into the ignition lock.
  • Turn the key briefly to position 2. The ignition key automatically returns to position 1. Do not press the accelerator pedal when doing this.
  • The engine will start and the vehicle will then be ready to drive.

Equipment that uses a lot of electricity is switched off temporarily when you start the engine. If the engine does not start immediately, stop the starting procedure by turning the ignition key to position 0 and repeat after 30 seconds.

If it is difficult to turn the key to position 1, turn the steering wheel back and forth slightly to release the steering lock.

Stopping the engine

  • Bring the vehicle to a full stop.
  • Turn the key to position 0. The engine will switch off.

Activating the steering lock

Applies to: vehicles with steering lock

The steering lock helps prevent vehicle theft.

  • Remove the ignition key.
  • Turn the steering wheel until the steering wheel audibly locks.

Switching the ignition on or off

If you would like to switch the ignition on or off without starting the engine, follow these steps:

  • Switching on: turn the key to position 1.
  • Switching off: turn the key to position 0.


Never remove the ignition key from the ignition lock while the vehicle is moving. Otherwise, the steering lock could engage and you would not be able to steer the vehicle, which increases the risk of an accident.

General information


  • To reduce the risk of asphyxiation, never allow the engine to run in confined spaces.
  • Never turn off the engine before the vehicle has come to a complete stop and the "P" selector lever position is engaged. Switching it off before the vehicle has stopped may impair the function of the brake booster and power steering. You would then need to use more force to steer and brake the vehicle.

    The fact that you cannot steer and brake as usual may increase the risk of accidents and serious injuries.

  • Secure the vehicle against rolling before exiting the vehicle.


  • Avoid high engine speed, full throttle, and heavy engine load if the engine has not reached operating temperature yet. You could damage the engine.
  • If the engine has been under heavy load for an extended period of time, heat builds up in the engine compartment after the engine is switched off and there is a risk of damaging the engine. For this reason, let the engine run at idle for approximately two minutes before shutting it off.


  • Brief noises are normal when starting and parking the vehicle and are no cause for concern.
  • For up to 10 minutes after stopping the engine, the radiator fan may turn on again automatically or it may continue to run, even if the ignition is switched off.
  • It may not be possible to start the vehicle in extremely low temperatures.
  • Power will be fully available once the engine is at operating temperature.
