Battery Information
The QX60 HYBRID utilizes two batteries in order to supply both high and low voltage.
2-1.1 12-Volt Battery • The QX60 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

High-Voltage Battery
• The QX60 HYBRID contains a high-voltage battery.
• 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 AAYIA0300ZZ

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 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.
• QX60 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.

4-3.2 Towing Guidelines
Infiniti strongly recommends that QX60 HYBRID be towed with the driving wheels off the ground or that the
vehicle be placed on a flatbed truck. • AWD Models: Never tow with any of the wheels on the ground, as this may cause
serious
and expensive damage to the powertrain.
• FWD Models: Never tow with the front wheels on the ground, as this may cause serious and expensive damage to the powertrain.
• Transport the vehicle only after turning the ignition switch OFF.
• Safety chains or cables must be attached only to the main structural members of the vehicle. Otherwise, the vehicle body will be damaged.
• Do not use the vehicle tie down points to free a vehicle stuck in sand, snow, mud, etc.
• Never tow a vehicle using the vehicle tie down.
• Always pull the recovery device straight out from the vehicle. Never pull on the vehicle at an angle.
• Pulling devices should be routed so they do not touch any part of the suspension, steering, brake, high-voltage or cooling systems.
• Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or recovery.
