Fuel inertia switch

The fuel inertia switch is a safety device which deactivates the fuel
pump relays if a collision occurs.
A specific symbol appears on the left TFT display (see page 109)
and the hazard warning lights activate to indicate that this switch
has been triggered.
When the fuel inertia switch is activated, the doors are also
unlocked (if locked) and the central dome light comes on.
Warning
The fuel pump relays can be reactivated by pressing button A on
the floor in front of the driver's seat.
