DISCONNECT THE 12V BATTERY BEFORE SERVICING THE DIRECT CURRENT TO ALTERNATING CURRENT (DC-AC) INVERTER
OR ALTERNATING CURRENT (AC) POWERPOINT TO PREVENT THE RISK OF HIGH VOLTAGE SHOCK. FAILURE TO FOLLOW THIS
INSTRUCTION MAY RESULT IN SERIOUS PERSONAL INJURY.
NOTE:
If the vehicle has a stuck on charge plug, perform the 12v battery disconnect steps after the charge plug has been removed. Follow
the procedure in Section 3.
NOTICE:
Disconnecting the 12v battery alone does not necessarily disable the 12v power in the vehicle. The vehicle must be keyed off (and
unplugged, if the vehicle is a plug-in hybrid,) to ensure the DC/DC converter is not powering the 12v system.
