2014 INFINITI QX60 HYBRID ignition

• The high voltage battery relays (SMR1 and SMR2) will automatically open to stop the electrical flowin a front, side or certain rear collisions that are sufficient enough to activate the supplemental
restraint system (SRS) .
2-6 High Voltage Circuit Shut-Off System
This vehicle is equipped with a system to shut off the current from the Li-ion battery by the following methods:
Service plug Positioned in the right rear area of the Li-ion battery, this plug shuts off the output of high voltage when manually removed.
System main relays
(located in the high voltagebattery) Controlled by the ignition switch, these relays are powered by the 12V sys-
tem and shut off high voltage from the Li-ion battery.
Emergency shut-off sys-tem In the case of a collision (front and side collisions in which the air bags are
deployed, certain rear collisions) or certain system malfunctions this system
is designed to shut off the high voltage from the Li-ion battery.
2-7 Preventing Electrical Shock 1. If it is necessary to touch any of the high voltage harnesses or components, always wearappropriate Personal Protective Equipment (PPE) [refer to
3-1 Preparation Items (FRG–18)].
Shut off the high voltage system by referring to
3-3.1 High Voltage System Shut-Down
Procedure (FRG–20)
.
2. To avoid the risk of electrocution, NEVER touch the inside of the Li-ion battery with bare hands after shutting off the high voltage system. The Li-ion battery maintains charge even though the
high voltage system is shut down. PPE must always be worn when touching or working on high
voltage components.
3. Cover damaged high voltage components with insulated tape.
2-8 Emergency Medical Equipment
The high voltage system should not interfere with emergency medical equipment which must be used in or
near the vehicle at an accident scene. FRG–16

Primary Procedure
NOTE:Before disconnecting the 12V battery terminal, if necessary, lower the windows, adjust the
steering column, adjust the seats, unlock the doors, etc. Once 12V battery is disconnected,
power controls will not operate.
1. If possible, check the READY
indicator status in the instrument cluster. If it is on, the high
voltage system is active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch once to turn OFF the high voltage system. Verify that the READY indicator is off and
then continue to the next steps to open the hood for
12V battery negative cable access.
If the READY indicator does not turn off, refer to
Alter-
nate Procedure 1 (Remove Fuses) (FRG–25)
4. If possible, keep the INFINITI Intelligent Key™ at least 5 meters (16 feet) away from the vehicle.
5. Pull release handle (1) and pull up release lever (2) to open hood.

Alternate Procedure 2 (Remove Service Plug)
•Do not remove the service plug without always wearing appropriate Personal
Protective Equipment (PPE) to help protect the responder from serious injury or death
by electrical shock.
•
Immediately cover the service plug socket with insulated tape. The Li-ion battery
retains high voltage power even when the service plug is removed. To avoid electric
shock, NEVER touch the terminals inside the socket.
To avoid unintended reinstallation and risk of electrical shock and severe personal injury
or death, the rescuer should carry the service plug on his/her person while work is in progress.
NOTE: Before disconnecting the 12V battery terminal, if necessary, lower the windows, adjust the
steering column, adjust the seats, unlock the doors, etc. Once 12V battery is disconnected,
power controls will not operate.
1. If possible, check the READY
indicator status in the instrument cluster. If it is on, the high
voltage system is active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch once to turn OFF the high voltage system. Then verify whether the READY indicator
is off.
If the READY indicator does not turn off, continue to the
next steps.

12. Disconnect negative (-) battery cable and cover it withinsulated tape.
13. Perform the first response action.
3-3.2 Water Submersion
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 breathingapparatus during fire fighting operations. Smoke from a QX60 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 Li-ion battery case.
3-3.4 Cutting the Vehicle Body
•Do not cut into high voltage related areas to avoid severe personal injury or death.
•
Do not cut into the Li-ion battery to avoid severe personal injury or death.
•
When removing parts, NEVER touch the high voltage parts or the insides of the
exposed orange-colored high voltage cables to avoid severe personal injury or death.
Personal Protective Equipment (PPE) must always be worn when touching or
working on high voltage components.
Do not cut air bag parts to avoid unintended deployment of the air bags and the risk of
severe personal injury or death.
If at least approximately ten (10) minutes have passed since the rescuer shut down the high voltage
system [refer to
3-3.1 High Voltage System Shut-Down Procedure (FRG–20)], then the rescuer can cut the
vehicle except for the Li-ion battery.
If the rescuer cannot wait approximately ten (10) minutes or shut down the high voltage
system, absolute care must be taken to avoid cutting HV parts and appropriate Personal
Protective Equipment (PPE) must always be worn. DO NOT cut the Li-ion battery due to
possible electrocution risk and electrolyte solution leakage. FRG–32
