If the engine fails to start straight-away, switch off the starter after about 10 seconds and try again after about half a minute.

Driver messages in the instrument cluster display
No key identified
This message appears when you press the Start/Stop button if there is no remote control key inside the Audi Q5 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. Electronic equipment, such as mobile phones, can also interfere with the radio signal from the key.
Press brake pedal to start engine
This message appears on automatic Audi Q5s if you press the Start/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 to start engine
This message appears on manual Audi Q5s if you press the Start/Stop button to start the engine without first pressing the clutch pedal. The engine will only start if you press the clutch pedal.
Engage N or P to start engine
This message will appear if you try to start the engine when the selector lever of the automatic gearbox is not in P or N. The engine can only be started if the selector lever is in one of these positions.
Key not in Audi Q5If the indicator lamp lights up and the message appears, the remote control key was removed from the Audi Q5 while the engine was running. If the remote control key is not in the Audi Q5 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 Q5 from the outside.
Shift to P, otherwise Audi Q5 can roll away. Doors do not lock if lever is not 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/Stop button. Put the selector lever in position P; otherwise the Audi Q5 can roll away. If the lever is not in position P you will not be able to lock the Audi Q5 using the locking sensor on the door handle or the remote control key.
Convenience key defective ! Use ignition lock
This message appears if the engine has to be started or stopped using the ignition key instead of the Start/Stop button.
Steering lock
The steering is locked if the key is not in the ignition and the driver's door has been opened. The steering lock acts as a theft deterrent.
Never run the engine in confined spaces. The exhaust gases are toxic.
- Never switch off the engine until the Audi Q5 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 Q5 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.
- The engine cannot be started by push-starting or towing.
Note
If you open the driver's door while the ignition is switched on, a warning buzzer will sound, and the message Ignition is on will appear in the display. In this case, please switch off the ignition.
