1. About the INFINITI Q50 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 behind
the rear seat back with battery cable access through the trunk area. The other is the high voltage battery for
the traction motor which propels the vehicle. The high voltage battery is located behind the rear seat back
with service plug access through the trunk area.
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.FRG–5

2-4 High Voltage Safety Measures
Circuit insulation The high voltage positive (+) and negative (-) circuits are insulatedfrom 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
WARNING/AVERTISSEMENT
To avoid serious injury, keep clear engine parts at all times. Engine may start at any time if the start switch and the the READY lamps
on the instrument panel are "ON". Make sure both lamps are "OFF" before working in the engine compartment. See Owners Manual.
Pour éviter des blessures graves, assurez-vous que les témoins START SWITCH et READY dans le tableau d e bord sont éteints
(OFF) avant d'entreprendre tout travail à I'intérieur du compartiment moteur. Le moteur peut démarrer à tout moment si le contacteur
d'allumage est à la position ON et que les témoins READY du tableau de bord sont allumés. Assurez-vous que les deux
témoins sont éteints avant de travailler dans le compartiment moteur. Reportez-vous au manuel du conducteur.

2-5 High Voltage Safety System
The high voltage safety system is intended to help keep vehicle occupants and emergency responders safe
from high voltage electricity.• A high voltage fuse provides short circuit protection inside the high voltage battery.
• The high voltage safety system is insulated from the metal chassis.
• Positive and negative high voltage power cables are connected to the high voltage battery and arecontrolled by normally open system main relays (SMR1 and SMR2) . When the vehicle is shut off,
the relays stop electrical flow from leaving the high voltage battery. However, it can take
approximately ten (10) minutes for the high voltage capacitor to fully discharge.
• The high voltage system and high voltage capacitor may remain powered for up to
approximately 10 minutes after the vehicle is shut off. 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. 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 front, side or certain rear collisions that are sufficient enough to activate the supplemental
restraint system (SRS) .

3-3.5 High Voltage Battery Damage And Fluid Leaks
The high voltage battery contains electrolyte solution. To avoid exposure to electrolyte
solution and serious personal injury, always wear appropriate solvent resistant Personal
Protective Equipment (PPE) and read the following precautions:
• Electrolyte solution is a skin irritant.
• Electrolyte solution is an eye irritant – If contact with eyes, rinse with plenty of water andsee a doctor immediately.
• If electrolyte leak occurs, wear appropriate solvent resistant PPE and use a dry cloth to clean up the spilled electrolyte. Be sure to adequately ventilate the area.
• Electrolyte solution is highly flammable.
• Electrolyte liquid or fumes that have come into contact with water vapors in the air will create an oxidized substance. This substance may irritate skin and eyes. In these cases,
rinse with plenty of water and see a doctor immediately.
• Electrolyte fumes (when inhaled) can cause respiratory irritation and acute intoxication. Move to fresh air and wash mouth with water. See a doctor immediately.
If electrolyte solution leakage, or damage such as any problem with the high voltage battery casing are
observed, first responders should attempt to neutralize the battery by applying a large volume of water to
the battery pack while wearing appropriate Personal Protective Equipment (PPE) . The neutralization
process helps stabilize the thermal condition of the battery pack but does not discharge the battery.
High Voltage Battery Electrolyte Solution Characteristics: • Clear in color
• Sweet odor
• Similar viscosity to water
• Since the high voltage battery is made up of many small sealed battery modules, electrolyte solutionleakage should be minimal.
NOTE:
Other fluids in the vehicle (such as engine oil, washer fluid, brake fluid, coolant, etc.) are
the same as those in a conventional vehicle.
3-3.6 Accessing the Occupants 1. Remove windowsa. Perform window removal the same as a normal vehicle.
2. Remove doors a. The doors are removable with hand tools or basic rescue tools such as electrical/hydraulicrescue tools. It may be easier to remove the doors by cutting door hinges.
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.
