■The protection circuit may be activated to cut the power supply if any of the fol-
lowing conditions apply:
●Use of electrical appliances exceeding 100 W is attempted.
A sound may be heard when the protection circuit is activated. This is normal
and does not indicate a malfunction.
●The total power usage by all electrical features (headlights, air conditioning,
etc.) has exceeded the total vehicle maximum for an extended period of time.
■If the protection circuit is activated and the power supply is cut, conduct the fol-
lowing procedure:Park the vehicle in a safe place, and then securely apply the parking brake.
Make sure that the power consumption of the electric appliance is within
the maximum capacity of the power outlet and the appliance is not bro-
ken.
