An electric engine heater and passenger compartment heater ensure that the car is warm and comfortable to climb into, even on very cold winter days. Starting an already warm engine subjects the engine to less wear and consumes less fuel, thereby producing fewer harmful exhaust fumes.

The front socket is mounted in the front bumper, which gives an integrated impression and makes it easily accessible. The engine heater can be supplemented with a passenger compartment connection kit which allows connection of a passenger compartment heater.

The ideal preheating time with an electric engine heater is 2-3 hours. This is enough to raise the temperature of the engine to 20-30 °C above the outside temperature. After that the temperature does not increase and the electric current is used only to maintain the temperature.
