The fuel switch used by the VSI-system controls the following functions:
The fuel switch is operated by a touch key to switch from petrol to LPG and vice-versa. The fuel switch is also equipped with LED indicators to monitor the level of the fuel in the tank. When the LPG level is too low the reserve LED lights up. When there is an automatic switch-over to petrol because the LPG tank is empty, the driver is being warned by a buzzer signal and a flashing LED indicator.
