1. About the INFINITI Q50 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. The 12-volt battery is located behind
the rear seat back with battery cable access through the trunk area. The other is the high-voltage battery for
the traction motor which propels the vehicle. The high-voltage battery is located behind the rear seat back
with service plug access through the trunk area.
When the high-voltage battery level is low, engine output is used to generate power from the traction motor
and charge the high-voltage battery. Additionally, the vehicle system can recharge the high-voltage battery
by converting driving force into electricity while the vehicle is decelerating or being driven downhill. This
is called regenerative charging.

• 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 12V 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 12V 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 trunk, 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 power switch and disconnect the 12-volt battery. Refer to Primary Procedure
(FRG–22) .
•
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–25) .
•
Remove the service plug and disconnect the 12-volt battery. Refer to Alternate Procedure 2
(Remove
Service Plug) (FRG–28) .
