Autokäynnistys

Autokäynnistys, also known as remote engine start, is a feature that allows a vehicle's engine to be started without a person physically present inside the car. This is typically achieved through a key fob, a smartphone application, or an automated scheduling system. The primary purpose of autokäynnistys is to allow the vehicle's interior to be pre-heated or pre-cooled before the driver enters, enhancing comfort, especially in extreme weather conditions.

The system works by sending a signal to the vehicle's computer, which then initiates the standard starting sequence. Once the engine is running, the climate control system can be activated, bringing the cabin temperature to a desired level. Some autokäynnistys systems also allow for the operation of other features, such as defrosters or seat heaters. The engine will typically run for a predetermined period or until the vehicle's doors are opened, at which point it may shut off for security reasons.

Autokäynnistys systems are commonly found in newer vehicles, often as an optional upgrade or part of a premium trim package. They can also be installed as aftermarket devices. While convenient, users should be aware of local regulations regarding engine idling and potential emissions. The technology relies on a secure communication protocol between the remote device and the vehicle to prevent unauthorized use.
