Before starting the engine with the alcohol lock*
The alcohol lock is activated automatically and is then ready for use when the car is opened.
To bear in mind
In order to obtain correct function and as accurate a measurement result as possible:
- Avoid eating or drinking approx. 5 minutes before the breath test.
- Avoid excess windscreen washing - the alcohol in the washer fluid may result in an incorrect measurement result.
After a completed period of driving, the engine can be restarted within 30 minutes without a new breath test.Note
