High-voltage Safety System
The high-voltage safety system is intended to help keep vehicle occupants and emergency responders safe
from high-voltage electricity. • A high-voltage fuse provides short circuit protection inside the high-voltage battery.
• The high-voltage safety system is insulated from the metal chassis.
• Positive and negative high-voltage power cables are connected to the high-voltage battery and arecontrolled by normally open system main relays (SMR1 and SMR2) . When the vehicle is shut off,
the relays stop electrical flow from leaving the high-voltage battery. However, it can take
approximately ten (10) minutes for the high-voltage capacitor to fully discharge. AAYIA0456ZZ

3. Emergency Response Steps
DANGER
• Failure to properly shut down the high-voltage electrical 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.
• If it is necessary to touch any of the high-voltage harnesses or components you
must
always wear appropriate PPE to avoid electrical shock. PPE must always be worn
when touching or working on high-voltage components. Shut down the high-voltage
system by following the steps outlined in 3-3.1 High-voltage System Shut-Down
Procedure

(FRG–21) Wait approximately ten (10) minutes for complete discharge of
the

high-voltage capacitor after the high-voltage system has been shut down. • NEVER assume the Q50 HYBRID is shut OFF simply because it is quiet.
•

If the READY indicator is ON the high-voltage system is active.
•

If possible, be sure to check the READY indicator on the instrument cluster and
verify

that the READY indicator is OFF and the high-voltage system is stopped.

Perform an inspection of the Personal Protective Equipment (PPE) items before beginning work. Do not use
any damaged PPE items.
3-1.2 Daily Inspection
This inspection is performed before and after use. The responder who will be using the items should
perform the inspection and check for deterioration and damage. • Insulated rubber gloves should be inspected for scratches, holes and tears. (Visual check and airleakage test)
• Insulated safety boots should be inspected for holes, damage, nails, metal pieces, wear or other problems on the soles. (Visual check)
• Insulated rubber sheet should be inspected for tears. (Visual check)
3-1.3 Insulated Tools

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 Q50 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 Infiniti Q50 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 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 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 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 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.
