1-3 Warning and Indicator Lamp Information1. Master Warning Lamp (Orange or Red) 2. Hybrid System Overheated Stop Vehicle Warning (Vehicle Information Display)
3. Hybrid System Warning Lamp (Orange) 4. READY Indicator (Green)
Lamp Name Icon Description
READY 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 (Orange)
This lamp is on or blinking when:
• Malfunction has occurred in the hybrid control 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.

2-5 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.
• The high voltage system and high voltage capacitor may remain powered for up to
approximately 10 minutes after the vehicle is shut off. Personal Protective Equipment
(PPE) must always be worn when touching or working on high voltage components
to avoid risk of electrical shock and severe personal injury or death.
• The high voltage battery retains high voltage at all times. PPE must always be worn when touching or working on high voltage components to avoid risk of electrical shock and
severe personal injury or death.
• 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 front, side or certain rear collisions that are sufficient enough to activate the supplemental
restraint system (SRS) .

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 beworn
when touching or working on high voltage components. Shut downthe high voltage
system by following the steps outlined in
3-3.1 High Voltage System Shut-Down
Procedure (FRG–20)
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 thehigh voltage system is active.
• If possible, besure to check the READY
indicator on the instrument cluster and
verify that theREADY
indicatoris OFF and the high voltage system is stopped.

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–21)
.
• Disconnect the underhood fuse panel terminal connector for the high voltage control system and disconnect the 12-volt battery. Refer to
Alternate Procedure 1 (Disconnect Underhood Fuse
Panel) (FRG–24)
.
• Remove the service plug and disconnect the 12-volt battery. Refer to
Alternate Procedure 2
(Remove Service Plug) (FRG–27)
.
Primary Procedure
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. Verify that the READY indicator is off
and then continue to the next steps to open the trunk for
12-volt battery negative cable access.
If the READY indicator does not turn off, refer to
Alternate Procedure 1 (Disconnect Underhood Fuse
Panel) (FRG–24)
4. If possible, keep the Infiniti Intelligent Key at least5 meters (16 feet) away from the vehicle (except to
open the trunk as noted below) .

Alternate Procedure 2 (Remove Service Plug)
DANGER
•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 the
next steps to open the trunk for 12-volt battery negative
cable access.
