INFINITI QX60 HYBRID 2017 First Responder´s 1. About the QX60 HYBRID
This
hybrid electric vehicle (HEV) uses two types of batteries. One is a 12-volt battery that is the same as
the battery in vehicles powered by internal combustion engines. Th

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.

a
pacemaker or other medical device is close to these parts, the medical device may be

• 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 verify that the READY indicator is off (if possible) , and the high-voltage
system

is stopped.
• After the high-voltage system is shut down, please wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor. While waiting, do not operate any
vehicle functions.
NOTE:
The high-voltage full discharge takes approximately ten (10) minutes.
• After shutting down the high-voltage system and removing the 12-volt battery negative (-) terminal, wait at least three (3) minutes to discharge the air bag capacitor. Even though
the 12-volt battery negative (-) is disconnected, the Supplemental Restraint System (SRS)
air bag maintains voltage at least three (3) minutes. During this time, there is a possibility
of sudden SRS air bag inflation due to harness short circuit or damage and it may cause
serious injuries.
• The 12-volt system will remain active even after the 12-volt battery negative (-) terminal is removed while the high-voltage system is active.This is because the charging system will
not shut down and power will be supplied to the 12-volt system and high-voltage system
continuously.
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust the steering
column, adjust the seats, unlock the doors, open the liftgate, etc. as required. Once the 12-volt 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 ignition switch and disconnect the 12-volt battery.Refer to Primary Procedure (FRG–23) .
•

Remove the underhood fuse for the high-voltage control system and disconnect the 12-volt battery.
Refer to Alternate Procedure 1 (Remove Fuses) (FRG–25).
•

Remove the service plug and disconnect the 12-volt battery. Refer to Alternate Procedure 2
(Remove

Service Plug) (FRG–27) .
