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
