eTow is an electronic installation/app that allows you to test the condition of your trailer or caravan from your smartphone.
- checks that your turn signals, rear lights and brake lights are working properly;
- checks your battery’s voltage;
- checks the tire pressure of the trailer or caravan even when you are driving;
- notifies you if your spare tire is missing or does not have the correct tire pressure;
- activates an alternative emergency light in case of failure of one of the lights.
The system can be installed by authorized aftermarket tire centers or dealers.
