3-3 How to Handle a Damaged Vehicle at an Accident Scene
NO
TE:
If any air bags have deployed in the following 3 situations, the high-voltage (HV) system has
been designed to automatically shut off at the time of deployment.
The Nissan Murano HYBRID 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. 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 an Nissan Murano HYBRID, 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
2-2 High-voltage-Related and 12-Volt-Related Component Locations and Descriptions (FRG–11).
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 (HV) 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 operations can begin immediately, and no wait period
is necessary.
Situation 2) High-voltage (HV) 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 never to cut through or damage any HV system
wiring, battery or components within approximately ten (10) minutes of HV system shut down,
but occupant assistance operations using extrication equipment can begin immediately. The locations of the
HV component parts are illustrated in this guide.
Situation 3) High-voltage (HV) system damaged
If there is any evidence that the HV system has been compromised (such as arcing/sparking, orange wiring
harnesses cut or damaged, HV component casings damaged, etc.) , the responder may still be at risk of
high-voltage exposure. The vehicle must be approached with extreme caution prior to initiating any system
shut down procedures or rendering assistance to occupants. Appropriate PPE must always be worn as
described in this guide, and the approximate ten (10) minute wait time must be observed after HV
system shut down in order to ensure the system is de-energized.
In rare situations where vehicle damage is very severe, HV system shut down procedures as described in
this guide may not work. In these instances extreme caution and appropriate risk management must be
followed to prevent shock or electrocution to the responder or occupant.
FRG–21

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 can
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. 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) . Appropriate 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 12-volt 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 12-volt system and high-voltage system
continuously.
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust the steering
column, adjust the seats, unlock the doors, open the liftgate, etc. as required. Once the 12-volt battery is
disconnected, power controls will not operate.
