Petrol engines
All models with a petrol injection system are equipped with a safety switch, which in an emergency or overload situation switches off the fuel pump. The switch is located in front of the driver's door on the left side wall. If the current circuit is open, the button is in the upper position.
Turning on
Look through the peephole in the side trim of the footwell. If the button is in the down position (picture), the electrical circuit is closed. If the button is in the up position, the switch has turned off the fuel pump.

Warning! If a leak is detected after an accident or if there is a smell of gasoline, do not turn on the switch, as there is a risk of fire or injury due to leaking gasoline.
Turn off the ignition.
Visually check the fuel system for leaks. If you can't see or smell gasoline leaking out, you can press the switch button.
Turn on the ignition, the operation of the fuel pump is clearly audible, pressure is created in the system.
Turn off the ignition and visually check the fuel system again for leaks; if necessary, eliminate the leak.
Replacement

Unscrew the three mounting bolts of the side footwell trim and remove it.
Slide the insulating material on the switch and remove the two switch mounting bolts.
Using a screwdriver, disconnect the multi-pole plug from the safety switch.
The switch is installed in the reverse order compared to its dismantling.
