Renault Megane 4
If the vehicle is equipped with a deadlocking function, this allows you to lock the opening elements and to prevent the doors from being unlocked using the interior handles (for example, by breaking the window and then trying to open the door from the inside).
To do this, press button 1 twice in quick succession.
The hazard warning lights and side indicator lights give two slow flashes and three quick flashes to indicate locking.
Special note: deadlocking is not possible if the hazard warning lights or the side lights are lit.
Never use deadlocking if someone is still inside the vehicle.
