3-3.1 High Voltage System Shut-Down Procedure
Any of the following procedures can shut down the high voltage system. The first response operation should
only begin after shutting down the high voltage system. If the vehicle is heavily damaged, for example the
high voltage battery is deformed, broken or cracked, appropriate PPE must always be used and the high
voltage battery and high voltage components must not be touched. PPE must always be worn when
touching or working on high voltage components.
DANGER
•Failure to properly shut down the high voltage system before the Emergency
Response Procedures are performed will result in serious injury or death from electrical
shock. To prevent serious injury or death, NEVER touch high voltage harnesses or
components without always wearing appropriate Personal Protective Equipment (PPE) .
PPE must always be worn when touching or working on high voltage components.
•When contact with high voltage components or high voltage harnesses is
unavoidable, or when there is risk of such contact, you must always wear appropriate
PPE. PPE must always be worn when touching or working on high voltage components.
•The vehicle contains parts that contain powerful magnets. If a person who is wearing
a pacemaker or other medical device is close to these parts, the medical device may be
affected by the magnets. Such persons must not perform work on the vehicle.
• Be sure to verify that the READY
indicator is off (if possible) , and the high voltage
system is stopped.
• After the high voltage system is shut down, please wait approximately ten (10) minutes for complete discharge of the high voltage capacitor. While waiting, do not operate any
vehicle functions.
NOTE:
The high voltage full discharge takes approximately ten (10) minutes.
• After shutting down the high voltage system and removing the 12-volt battery negative (-) terminal, wait at least three (3) minutes to discharge the air bag capacitor. Even though
the 12-volt battery negative (-) is disconnected, the Supplemental Restraint System (SRS)
air bag maintains voltage at least three (3) minutes. During this time, there is a possibility
of sudden SRS air bag inflation due to harness short circuit or damage and it may cause
serious injuries.
• The 12V system will remain active even after the 12-volt battery negative (-) terminal is removed while the high voltage system is active.This is because the charging system
will not shut down and power will be supplied to the 12V system and high voltage systemcontinuously.
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust the steering
column, adjust the seats, unlock the doors, open the trunk, etc. as required. Once the 12-volt battery is
disconnected, power controls will not operate. FRG–20
