NISSAN 2011 LEAF - First Responder's Guide - Manual (Page 23)

3. Remove the service plug by pressing the locking tab (1) and rotating the handle (2) upward.
Using the handle, pull the service plug completely out of its socket.
4. Wait at least ten (10) minutes for complete discharge of the high voltage capacitor after the
service plug has been removed.
5. Open the hood.
6. Disconnect the negative (-) 12V battery cable (1).
Insulate the negative (-) battery cable terminal with
insulated tape.
7. Perform the first response action.
NOTE:
If any air bags have deployed in the following 3 situations, the high-voltage (HV) system has
been automatically shut off at the time of deployment.
The Nissan LEAF high-voltage system incorporates capacitors which are energized whenever the high-
voltage system is on. If the high-voltage system is shut down (either through one of the built-in automatic
mechanisms or manually through one of the procedures explained in this FRG), the capacitors will begin to
gradually discharge. After 5 minutes, the voltage level will have dropped below 60V, and complete
discharge requires approximately 10 minutes after high-voltage system shut down. It is within this period of
time that responders must be most cautious.
When arriving to an incident involving a Nissan LEAF, the vehicle should be approached with caution and
inspected for the level of damage. In addition to overall vehicle condition (location and severity of body
damage, air bag deployment, etc.), the high-voltage system should be assessed specifically. The locations
of the high-voltage component parts are illustrated in this FRG. Refer to
2-1 High Voltage-Related and 12V-
Related Component Locations and Descriptions . Appropriate personal protective equipment (PPE) must
always be worn when approaching a vehicle of unknown condition, as described in this FRG.
Situation 1) High voltage system intact, occupants can be accessed without extrication tools
The HV system can be shut down by following the procedure in this guide, while wearing appropriate PPE.
After HV system shut down, occupant assistance can begin immediately, and no wait period is necessary.
Situation 2) High voltage system intact, occupants cannot be accessed without extrication tools
The HV system can be shut down by following the procedure in this guide, while wearing appropriate PPE.
After HV system shut down, absolute care must be taken not to cut through or damage any HV system
