1. About the QX60 HYBRID
This hybrid electric vehicle (HEV) uses two types of batteries. One is a 12V battery that is the same as the
battery in vehicles powered by internal combustion engines. The 12V battery is located under the hood near
the driver side headlamp. The other is the Lithium-ion (Li-ion) battery (high voltage) for the traction motor
which propels the vehicle. The Li-ion battery is located under the third row seating with service plug access
through the cargo area storage bin.
The high voltage Li-ion battery is recharged with an on-board DC/DC converter and generator powered by
the engine. Additionally, the vehicle system can recharge the Li-ion battery by converting driving force
into electricity while the vehicle is decelerating or being driven downhill. This is called regenerative charging.FRG–5
•Failure to properly shut down the high voltage 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.
•
When contact with high voltage components or high voltage harnesses is
unavoidable, or when there is risk of such contact, you must always wear appropriate
PPE. PPE must always be worn when touching or working on high voltagecomponents.
•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 12V battery negative (-) terminal, wait at least 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 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 12V 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 systemcontinuously.
Before disconnecting the 12V 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 12V battery is disconnected,
power controls will not operate.
