eTow is an electronic installation/app that allows you to test the condition of your trailer or caravan from your smartphone.


  1. checks that your turn signals, rear lights and brake lights are working properly;
  2. checks your battery’s voltage;
  3. checks the tire pressure of the trailer or caravan even when you are driving;
  4. notifies you if your spare tire is missing or does not have the correct tire pressure;
  5. 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.
