Lamp Name
Icon Description
READ Y Indicator
(Green) This lamp is on when the high-voltage system is powered
up
and the vehicle is ready to drive.
Master Warning Lamp
(Orange or Red) This lamp is on when another warning lamp or message is
displayed
in the instrument cluster.
Hybrid System Warning
Lamp *1
(Orange) This lamp is on or blinking when:
•
Malfunction has occurred in the high-voltage system
and/or
• High-voltage leak to vehicle chassis and/or
• Emergency shut-off system has been activated. The shut-off system activates in the following conditions:
– Front and side collisions in which the air bags are deployed.
– Certain rear collisions.
– Certain high-voltage system malfunctions.
*1: When this lamp is ON, the READY Indicator will turn OFF.

• A ground fault monitor continuously monitors for high-voltage leakage to the metal chassis while the
vehicle is running. If a malfunction is detected, the HPCM (hybrid powertrain control module) will
illuminate the hybrid system warning lamp in the instrument cluster.
•
The high-voltage battery relays (SMR1 and SMR2) will automatically open to stop the electrical flow
in 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 high-voltage battery by the following
methods: Service plug
Positioned in the right rear area of the high-voltage battery, this plug shuts off
the
output of high-voltage when manually removed.
System main relays
(located in the high-
voltage battery) Controlled by the ignition switch, these relays are powered by the 12-volt
system and shut off high-voltage from the high-voltage battery.
Emergency shut-off
system 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 high-voltage 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–21) .
2.
To avoid the risk of electrocution, NEVER touch the inside of the high-voltage battery with bare
hands after shutting off the high-voltage system. The high-voltage 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.

3. Emergency Response Steps
• 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 QX60 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.

Primary Procedure
NO
TE:
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust
the steering column, adjust the seats, unlock the doors, etc. Once 12-volt 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 12-volt battery negative cable access.
If the READY indicator does not turn off, refer to
Alternate Procedure 1 (Remove Fuses) (FRG–25).
4.
If possible, keep the Infiniti Intelligent Key at least
5 meters (16 feet) away from the vehicle. AAYIA0191ZZ

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 high-voltage
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 12-volt battery terminal, if necessary, lower the windows, adjust
the steering column, adjust the seats, unlock the doors, etc. Once 12-volt 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
