The hybrid disconnect switch (a plunger mounted near
the driver-side chassis battery) opens the connection

the disconnect is active, the lithium-iron batteries cannot
provide electrical power to the chassis, nor can they be
charged.

To engage the hybrid disconnect switch, push the plunger
down. It will lock into the open position.

To disengage the hybrid disconnect switch, twist the
plunger clockwise. It will unlock and return to the closed
position.
