Battery In Luggage Compartment
Battery in Luggage Compartment
CAUTION!
• Vehicles with battery in luggage compartment is equipped with a battery isolator to increase crash safety. In the event of a collision, the airbag control module triggers a separation, which disrupts the power supply wiring to the starter and to the engine electronics. The battery cut-off takes place pyrotechnically through a very small explosive charge. To prevent accidentally triggering a separation when working on the battery or battery cut-off, you must first disconnect the battery. Refer to => [ Battery, Disconnecting and Connecting ] Battery, Disconnecting and Connecting.
• Observe safety precautions when working on battery isolation system. Refer to => [ Battery Interrupt Igniter, Safety Precautions ] Service Precautions.
• Observe notes for disposal of battery isolator units. Refer to => [ Battery Interrupt Igniter Disposal ] Battery Interrupt Igniter Disposal.
