WARNING: To prevent personal injury and / or death, ALWAYS REMEMBER the high-voltage
disconnect switch only disables the vehicle’s high-voltage system. The high-voltage disconnect switch
does NOT turn OFF the voltage in the S-box, the high-voltage batteries, and the cables between these
items. The vehicle 12 volt system could still be energized. ALWAYS turn OFF both the high-voltage
disconnect switch and the 12V disconnect switch whenever interacting with a damaged vehicle. NEVER
touch ORANGE cables without wearing appropriate Personal Protection Equipment (PPE).

Open the driver-side door.

Turn the RED high-voltage disconnect switch to OFF position (Figure 14 Item 2).

Lock the switch with a padlock to avoid anyone from turning it back ON.
Components in high-voltage zone 2 and high-voltage zone 3 remain live after the high-voltage disconnect switch
is turned OFF. These zones are located primarily between the frame rails on the underside of the vehicle and
are labeled as indicated in Figure 4.
