dont press the big red switch

[mammy_nun]

was having a look round for the map sensor in my megane and noticed a big red push button switch. switch is located near the passenger side wing. does anyone know what it does?

That's the inertia switch... in the event of an accident the car will detect the shunt and cut all power and fuelling. All cars these days do this and that big red button is hte master reset that restores everything.

If you're planning on using the car in a ram raid or as a get away car be sure to remove that switch first and jump the temrinals

With the car running whack the switch with a spanner/screwdriver, you'll see whta it does then lol

it only cuts power to the fuel pump.

Like chet says, trip it and it will just stop running. Push the button and it will start again.

Easy tenner when people hit big road bumps

LMAO @ That answer, classic, but if he does, and gets caught, make sure he don't say "a man on RR told me to do it"...lol
