Alcohol lock

The alcohol lock is a safety measure to prevent driving under the influence of alcohol. If your vehicle is equipped with an alcohol lock, you must take and pass a breathalyzer test before you can start your vehicle.

If you have connected an alcohol lock, it will integrate with some of your vehicle's systems. This means that you may receive messages from the alcohol lock directly in the instrument panel. The alcohol lock should be calibrated in accordance with current local laws and regulations on the legal limit for driving.

For information about a specific alcohol lock, please refer to the relevant alcohol lock manufacturer.

 Warning

The alcohol lock is an aid and does not exempt the driver from responsibility. It is always the responsibility of the driver to be sober and to drive the vehicle safely.

Using an alcohol lock

The alcohol lock automatically activates to be ready for use when the vehicle is unlocked. Follow the instructions included when the alcohol lock was installed, along with the messages presented on the instrument panel.

After completing a driving cycle, meaning that you have driven and then stopped, your vehicle can be restarted within 30 minutes without requiring a new breathalyzer test.

 Tip

Accurate measurement

Avoid eating or drinking approximately five minutes before the breath test.

Avoid excessive windshield washing, as the alcohol in the washer fluid may affect the alcohol lock.

Emergency bypass of the alcohol lock

In the event of an emergency or if the alcohol lock is not working, it is possible to bypass the alcohol lock. To do so, see the instructions provided with the alcohol lock or contact the manufacturer.
