Instruction book AUDI A1
 Audi A1   Controls   Driving  Ignition lock (electronic)
Applies to Audi A1s: with convenience key
You can use the START ENGINE STOP button to switch on the ignition and start the engine.
You can start your Audi A1 without handling the convenience key. You only need to have the key on your person.
Apply the handbrake firmly.
Manual gearbox: Press the clutch pedal all the way down and move the gear lever into neutral.
Automatic gearbox: Press the brake pedal and move the selector lever to position P or N WARNING!.
Press the START ENGINE STOP button Fig. 1. The engine should start.
Diesel engines can take a few seconds longer than usual to start on cold days. Please keep your foot on the clutch or brake pedal until the engine starts. The indicator lamp lights up while the glow plugs are preheating.
If the engine fails to start straight-away, switch off the starter after about 10 seconds and try again after about half a minute.
When starting from cold the engine may be a little noisy for the first few seconds until oil pressure has built up in the hydraulic tappets. This is quite normal and no cause for concern.
On Audi A1s with a start/stop system*, the ignition will be switched off if you press the START ENGINE STOP button during a stop phase.
Switching the ignition on/off
If you press the START ENGINE STOP button without pressing the clutch or brake pedal, the ignition will be switched on (and will be switched off if you press the button again). Diesel engines are preheated when the ignition is switched on.
Driver messages in the instrument cluster display
No key identified. See Owner's Manual
This message appears if there is no convenience key inside the Audi A1 or if the system cannot detect or identify the key. This can happen, for example, if the radio signal from the key is obstructed by a metal briefcase or similar, or if the key battery is weak. Electronic equipment, such as mobile phones, can also interfere with the radio signal from the key.
If you encounter any problems starting or stopping the engine, please refer to "What to do if the "START ENGINE STOP" button is inoperational" Link.
Press brake pedal
This message appears on automatic Audi A1s if you press the START ENGINE STOP button to start the engine without first pressing the brake pedal. The engine will only start if you press the brake pedal.
Press clutch pedal
This message appears on manual Audi A1s if you press the START ENGINE STOP button to start the engine without first pressing the clutch pedal. The engine will only start or stop if you press the clutch pedal.
Please engage N or P
This message will appear if you try to start or switch off the engine when the selector lever of the automatic gearbox is not in P or N. The engine can only be started or stopped if the selector lever is in one of these positions.
Key not in Audi A1?
If the indicator lamp lights up and the message appears, the convenience key was removed from the Audi A1 while the engine was running. If the convenience key is not in the Audi A1 you will not be able to switch on the ignition or restart the engine after it has been switched off. You will also not be able to lock the Audi A1 from the outside.
Shift to P, Audi A1 can roll away. Doors can only be locked in P
For safety reasons, this message will appear and a warning buzzer will sound if the selector lever of the automatic gearbox is not in position P when you switch off the ignition with the START ENGINE STOP button. Put the selector lever in position P; otherwise the Audi A1 can roll away. If the lever is not in position P you will not be able to lock the Audi A1 using the locking sensor on the door handle or the convenience key.
Ignition is on
This message appears if you open the driver's door while the ignition is switched on. You will also hear a warning buzzer. Please switch off the ignition.
WARNING!
  • Always take the key with you when leaving your Audi A1 - even if you only intend to be gone for a short time. This is especially important if children are left in the car. They might otherwise be able to start the engine or use power-operated equipment such as the electric windows - this could lead to injuries.
  • Never run the engine in confined spaces. The exhaust gases are toxic.
  • Never switch off the engine until the Audi A1 is stationary.
  • The brake servo and the power steering system work only when the engine is running. You need more strength to steer and brake the Audi A1 when the engine is switched off. This would mean a greater risk of accidents and serious injury, because you cannot steer and brake in the normal manner.
Caution!
Avoid high engine speeds, full throttle and extreme load conditions until the engine has reached its normal operating temperature, otherwise this can damage the engine.
For the sake of the environment
Do not warm up the engine by running it with the car stationary. You should drive off immediately whenever possible. This will help avoid unnecessary exhaust emissions.
