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 dis-
played

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. AAYIA0010GB

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. AAYIA0001GB

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–19) 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 Q70 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.
FRG–16

• 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 12V battery negative (-) terminal and wait for three (3) minutes to discharge the air bag capacitor. Even though the 12V 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 12V 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 12V 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 12V 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 12V battery. Refer to Primary Procedure (FRG–21).
•

Remove the fuse for the high voltage control system and disconnect the 12V battery. Refer to Alter-
nate

Procedure 1 (Remove Fuses) (FRG–23) .
•

Remove the service plug and disconnect the 12V battery. Refer to Alternate Procedure 2 (Remove
Service

Plug) (FRG–25) .FRG–20

Primary Procedure
NO
TE:
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. Check the READY indicator (A) status in the instrument cluster. If it is on, the high voltage systemis active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch (B) once to turn OFF the high voltage system. Then verify whether the READY indicator (A) is off.
If the READY indicator (A) does not turn off, continue to the next steps to open the trunk for 12V
battery negative cable access.
4. If possible, keep the Infiniti Intelligent Key at least 5 meters (16 feet) away from the vehicle (except as noted
below) .
5. Open the trunk using any of the following: a. push-button switch (C) on the lower LH side ofthe instrument panel.
b. trunk button (D) on the Infiniti Intelligent Key [press for longer than one (1) second].
c. trunk open request switch (E) (located above license plate)*.
d. with the mechanical key (F) housed inside the Infiniti Intelligent Key.
* You must have the Infiniti Intelligent Key within approximately 1 meter (3 feet) range of
trunk request switch to use the trunk open request switch function. AAYIA0062ZZ

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. Check the READY indicator (A) status in the instrument cluster. If it is on, the high voltage systemis active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch (B) once to turn OFF the high voltage system. Then verify whether the READY indicator (A) is off.
If the READY indicator (A) does not turn off, continue to the next steps to open the trunk for 12V
battery negative cable access. AAYIA0062ZZ
