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 Infiniti Q70 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. 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 an Infiniti Q70 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
V

oltage-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 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
wiring, battery or components within ten (10) minutes of HV system shut down, but occupant assistance
operations using extrication equipment can begin immediately. The locations of the HV components 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 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.

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. 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.
FRG–20

• 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 check the READY indicator (1) in the instrument cluster, and verify that the READY indicator is off and the high voltage system is stopped.
• After the high voltage system is shut down, please wait for approximately ten (10) minutes for complete discharge of the high voltage capacitor. While waiting, do not
operate any vehicle functions.
• Remove the 12-volt battery negative (-) terminal and wait for 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
for three (3) minutes. 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 DC/DC converter
will not shut down and power will be supplied to the 12V 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 trunk, etc. as required. Once the 12-volt battery is
disconnected, power controls will not operate.
Powering Down the High Voltage System
The high voltage system can be shut down with any 1 of the following procedures: • Turn OFF the power switch and disconnect the 12-volt battery. Refer to Primary Procedure
(FRG–22) .
•

Remove the fuse for the high voltage control system and disconnect the 12-volt battery.
Refer to Alternate Procedure 1 (Remove Fuses) (FRG–24).
•

Remove the service plug and disconnect the 12-volt battery. Refer to Alternate Procedure 2
(Remove

Service Plug) (FRG–26) . FRG–21

3-3.2 Water Submersion
DANGER
Damage level of submerged vehicle may not be apparent. Handling a submerged
vehicle without appropriate Personal Protective Equipment (PPE) will result in serious
injury or death from electrical shock. • The ignition switch of the submerged vehicle must be turned OFF first, if possible.
Then
the vehicle must be completely out of the water and drained to avoid electrical
shock.
• Always wear appropriate Personal Protective Equipment (PPE) and remove/drain
water
before removing the service plug when working on a vehicle after a fire or
submersion to avoid electrical shock.
• If the vehicle is in the water, to avoid electrical shock NEVER touch the high voltage
components,
harnesses or service plug. PPE must always be worn when touching or
working on high voltage components.
3-3.3 Vehicle Fire • Always utilize full Personal Protective Equipment (PPE) and self-contained breathing
apparatus
during fire fighting operations. Smoke from a Q70 HYBRID vehicle fire is
similar to smoke from a conventional vehicle fire.
• In the case of extinguishing a fire with water, large amounts of water from a fire hydrant (if possible) must be used. DO NOT extinguish fire with a small amount of water. In the event of a small fire, a Type ABC fire extinguisher may be used for an electrical fire
caused

by wiring harnesses, electrical components, etc. or oil fire.
Fire attack should follow standard fire fighting practices.
If you must walk away from the vehicle, notify an appropriate responder or a rescue person of the fact that
the vehicle is a hybrid vehicle and contains a high voltage system and warn all others.
During overhaul operations (late stage fire suppression process to examine for remaining sources of heat) ,
make sure the battery is fully cooled to avoid fire re-ignition. The battery could reignite if it is placed near fire.
To avoid possible electrical shock and serious personal injury, do not breach the high voltage battery case.
