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

4. Jump Starting
T
o start the hybrid system with a booster battery, the instructions and precautions below must be followed. If done incorrectly, jump starting can lead to a 12-volt battery explosion, resulting in severe
personal

injury or death. It could also damage your vehicle.
Jump starting provides power to the 12-volt system to allow the electrical systems to operate. The electrical
systems must be operating to allow the high-voltage battery to be charged. Jump starting does not charge
the high-voltage battery.
Discharged 12-volt battery may cause the following issues: • The instrument cluster cannot be displayed while the ignition switch is turned ON. (The hybridsystem cannot start.)
• Headlamps, horn, etc. are weak. • To avoid electrical shock, the high-voltage battery CANNOT be jump started.
•

Explosive hydrogen gas is always present in the vicinity of the 12-volt battery. Keep all
sparks and flames away from the 12-volt battery. Make sure the vent tube is mounted.
• Do not allow battery fluid to come into contact with eyes, skin, clothing or painted surfaces. Battery fluid is a corrosive sulfuric acid solution that can cause severe burns.
If the fluid comes into contact with anything, immediately flush the contacted area
with water.
• The booster battery must be rated at 12 volts. Use of an improperly rated battery can damage the vehicle.
• Whenever working on or near a 12-volt battery, always wear suitable eye protectors (for example, goggles or industrial safety spectacles) and remove rings, metal bands, or any
other jewelry. Do not lean over the 12-volt battery when jump starting.
• Do not attempt to jump start a frozen battery. It could explode and cause serious injury.
• Murano HYBRID is equipped with an automatic cooling fan. It could come on at any time. Keep hands and other objects away from it.
• Always follow the jump starting instructions below. Failure to do so could result in damage to the charging system and cause personal injury.
