1. About the Murano 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 in the front of
the vehicle on the left side of the engine compartment. The other is the high-voltage battery for the traction
motor which propels the vehicle. The high-voltage battery is located under the center console between the
driver’s and passenger’s seats with service plug access through the center console area storage bin.
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.

2. Basic High-voltage System and 12-volt System Information
2-1
Battery Information
The Murano HYBRID utilizes two batteries in order to supply both high and low voltage.
2-1.1 12-Volt Battery • The Murano HYBRID contains a conventional lead-acid12-volt battery.
• The 12-volt battery is located in the front of the vehicle on the left side of the engine compartment.
• The 12-volt battery is charged by the high-voltage battery through the DC/DC converter. : Vehicle front
2-1.2
High-voltage Battery
• The Murano HYBRID contains a high-voltage battery.
• The high-voltage battery is mounted under the center console and enclosed in a metal case.
• The high-voltage battery stores approximately 144 volts DC.
• A vent hose is provided to exhaust gasses outside the vehicle, if necessary.
• Air for battery cooling is drawn in from the front of the center console, under the instrument panel, and is vented
into the RH side B-pillar with the use of a fan located under
the passenger seat.
The high-voltage battery supplies power to the following: • High-voltage harnesses
• DC/DC converter
• Traction motor inverter
• Traction motor AAYIA0465ZZ

No. Component
LocationDescription
DC/DC
Converter Inside the centerconsole area
(mounted right of
high-voltage battery) The DC/DC converter reduces the voltage of
the high-voltage battery to provide power to
the 12-volt battery in order to operate the
vehicle’s electric components (headlights,
audio system, etc.) .
Service Plug Center console
(inside storage bin
under access door) This is used to disable the high-voltage system.
High-voltage
Battery Inside the center
console area
(between the
front driver’s and
passenger’s seats) The high-voltage battery stores and outputs
DC power (Maximum voltage 144V) needed to
propel the vehicle.
Traction Motor Engine compart-
ment (built-into the
transmission) Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
Traction Motor
Inverter
Engine compartment
(front driver side)Converts the DC power stored in the high-
voltage battery to three-phase AC power and
controls motor torque (revolution) by regulating
the motor current. The inverter has a built in
high-voltage capacitor.
12-volt Battery
Front of the vehicle
on the left side of the
engine compartment.A lead-acid battery that supplies power to the
low voltage devices.
High-voltage
Harness Center console area

2-4 High-voltage Safety Measures
Circuit insulation
The high-voltage positive (+) and negative (-) circuits are insulated
from the metal chassis.
Reducing the risk of electrocution The high-voltage components and harnesses have insulated cases or orange-colored coverings which provide insulation and easy
identification.
The high-voltage battery case is electrically connected to the vehicle
ground. This connection helps protect the vehicle occupants and
emergency responders from high-voltage electrical shock.
Identification The high-voltage components are labeled “WARNING” similar to label
shown below. All high-voltage harnesses are coated in orange.
2-4.1 Warning Labels
The following warning label is applied to the high-voltage inverter located in the engine compartment.
The following warning label is applied to the service plug access cover located inside the passenger
compartment center console. AAYIA0454ZZ

• The high-voltage system and high-voltage capacitor may remain powered for up to
approximately 10 minutes after the vehicle is shut off. Appropriate 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. Appropriate 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 a front, side or certain rear collisions that are sufficient enough to activate the supplemental
restraint system (SRS) . Passenger Compartment

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) .
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 hood
for 12-volt battery negative cable access.
If the READY indicator does not turn off, refer to
Alternate Procedure 1 (Remove Fuses) (FRG–25).
4.

If possible, keep the Nissan Intelligent Key® at least
5 meters (16 feet) away from the vehicle.P R N

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
step 4.
4. If possible, keep the Nissan Intelligent Key® at least 5 meters (16 feet) away from the vehicle.
