Battery master switch
The battery master switch (6.2.3.1) cuts off all electrical circuits (battery, generator,
lights, ignition and electrical controls, etc.) as well as the engine.
The battery master switch (Pos.2 in picture 6.2.3.2) is installed right next to the
battery. It´s located on the center tunnel and covered by the battery cover, as well as
the battery itself.
The battery master switch can be operated in two different ways:
Inside operation
The “Main” switch (1) which is located in the center console is used as the inside
actuator.
Outside operation
Another release mechanism for the battery master switch is located outside the
vehicle on the driver’s side at the bottom of the windshield. Pulling the red loop
activates the switch installed below the cowl and disconnects the battery from the
electrical system immediately.
