2. Basic High Voltage Information
2-1 Battery Information
The Pathfinder HYBRID utilizes two batteries in order to supply both high and low voltage.
2-1.1 12V Battery• The Pathfinder HYBRID contains a conventional lead-acid12 volt battery.
• The 12V battery is located in the front of the vehicle on the left side of the engine compartment, under a trim cover.
• The 12V battery is charged by the Li-ion battery through the DC/DC converter.

2-1.2 Li-ion Battery • The Pathfinder HYBRID contains a Li-ion high voltagebattery.
• The high voltage battery is mounted in the cargo area under the 3rd row seating, enclosed in a metal case
and concealed by trim cover.
• The high voltage battery stores approximately 144 volts DC.
• A vent hose is provided to exhaust gasses outside the vehicle, if necessary.
• Air vents (A) are located on the cargo area trim panels for battery cooling.
The high voltage battery supplies power to the following: • High voltage harnesses
• DC/DC converter
• Traction motor inverter
• Traction motor

4. Jump Starting
To 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 12V battery explosion, resulting in severe
personal injury or death. It could also damage your vehicle.
Jump starting provides power to the 12V system to allow the electrical systems to operate. The electrical
systems must be operating to allow the Li-ion battery to be charged. Jump starting does not charge the
Li-ion battery.
Discharged 12V 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 Li-ion battery CANNOT be jump started.
• Explosive hydrogen gas is always present in the vicinity of the 12V battery. Keep all sparks and flames away from the 12V 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 withwater.
• 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 12V 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 12V battery when jump starting.
• Do not attempt to jump start a frozen battery. It could explode and cause serious injury.
• Pathfinder 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.
