Removal of HV battery

WARNING:
Be sure to wear insulated gloves when handling high-voltage
parts.
Even if the vehicle is shut off and the relays are off, be sure to
remove the service plug grip before performing any further
work.
Power remains in the high voltage electrical system for 10
minutes even after the HV battery pack is shut off because the
circuit has a condenser that stores power.
Make sure that the tester reading is 0 V before touching any
high-voltage terminals which are not insulated.
The SRS may remain powered for up to 90 seconds after the
vehicle is shut off or disabled. To prevent serious injury or
death from unintentional SRS deployment, avoid cutting the
SRS components.
