2017 INFINITI Q50 HYBRID cooling

2. Basic High-voltage Information
2-1 Battery Information
The Q50 HYBRID utilizes two batteries in order to supply both high and low voltage.
2-1.1 12-Volt Battery• The Q50 HYBRID contains a conventional lead-acid12-volt battery.
• The 12-volt battery is located in the trunk, on the left side, concealed by a trim cover (A) .
• The 12-volt battery is charged by the high-voltage battery through the DC/DC converter.
2-1.2 High-voltage Battery • The Q50 HYBRID contains a high-voltage battery.
• The high-voltage battery is mounted in the trunk areabehind the rear seat, enclosed in a metal case and
concealed by trim cover.
• The high-voltage battery stores energy at approximately 346 - 400 volts DC.
• A vent hose is provided to exhaust gasses outside the vehicle if necessary.
• An air vent (A) is located on the rear left hand lower C-pillar trim for battery cooling.
The high-voltage battery supplies power to the following: • High-voltage harnesses
• DC/DC converter
• Traction motor inverter
• Traction motor
• Electric air conditioner compressor

4. Roadside Assistance
4-1 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.
• Q50 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 Q50 HYBRID be towed with the driving (rear) wheels off the ground or that a
dolly be used as illustrated.
• Never tow with the rear wheels on the ground or four (4) wheels on the ground (forwardor backward) , as this may cause serious and expensive damage to the motor.
• Never tow AWD models with any of the 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 hook to free a vehicle stuck in sand, snow, mud, etc.
• Never tow a vehicle using the vehicle tie down hook.
• Always pull the cable straight out from the front of 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.
Perform vehicle towing by holding up drive (rear) wheels or on flatbed in order to prevent secondary damage
from voltage generated by the motor. In addition, turn the ignition switch OFF when towing the vehicle. Refer to
the following illustrations:
