1. About the Q50 HYBRID
This hybrid electric vehicle (HEV) uses two types of batteries. One is a 12V battery that is the same as the
battery in vehicles powered by internal combustion engines. The 12V battery is located in the rear of the
vehicle with battery cable access through the trunk area. The other is the Lithium-ion (Li-ion) battery (high
voltage) for the traction motor which propels the vehicle. The Li-ion battery is located behind the rear
seat back with service plug access through the trunk area.
The high voltage Li-ion battery is recharged with an on-board DC/DC converter and generator powered by
the engine. Additionally, the vehicle system can recharge the Li-ion battery by converting driving force
into electricity while the vehicle is decelerating or being driven downhill. This is called regenerative charging. FRG–4

1-1.1 Exterior and Engine Compartment
AAYIA0177ZZFRG–5

No. Component Location Description Traction Motor Inverter
Engine compartment
(rear passengerside)Converts the DC power stored in the Li-ion
battery to three-phase AC power and controls
motor torque (revolution) by regulating the
motor current. The inverter has a built in high
voltage capacitor.
Traction Motor Built-into the
transmission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
Lithium-ion (Li-ion)Battery
Trunk area
(behind rear seatback) The Li-ion battery stores and outputs DC
power (Maximum voltage 400V) needed to
propel the vehicle.
DC/DC Converter Trunk area (mounted to top of
Li-ion battery) The DC/DC converter reduces the voltage of
the Li-ion battery to provide power to the 12V
battery in order to operate the vehicle’s electric
components (headlights, audio system, etc.) .
Service Plug Trunk area
(below parcel shelf;
behind access door
in trim panel) This is used to disable the high voltage system.
12V Battery Trunk area
(left side behind
trim panel) A lead-acid battery that supplies power to the
low voltage devices.
High VoltageHarnesses Trunk area
(on Li-ion battery) ,
under floor pan,
engine compartment Orange-colored power cables carry high DC
voltage between each of the high voltagecomponents.

3-1 Preparation Items
Preparation Items Specification Purpose
PPE (personal protective equipment):
Insulated gloves
Up to 1,000V For protection from high voltage
electrical shock
Insulated shoes
–
Safety shield
–
Wrenches
Size:10mm To remove the 12V battery terminal bolt.
Solvent resistant
protection gloves
Solvent resistant
protection shoes –
To utilize in the event of a Li-ion battery
electrolytic solution leak.
–
Absorbent pad The same pad used for internal com- bustion engine fluids can be used. To absorb any Li-ion battery electrolytic
solution leakage.
Standard fire fightingequipment Standard fire fighting equipment.
Depending on type of fire (vehicle or
battery) use standard fire fighting
equipment (water or extinguisher) . To extinguish a fire.
Insulated tape Insulating To cover any damaged harnesses to
protect from and prevent electrical
shock. Tape should cover all bare or
damaged wire.
3-1.1 Personal Protective Equipment (PPE) Protective Wear Control
Perform an inspection of the Personal Protective Equipment (PPE) items before beginning work. Do not use
any damaged PPE items. FRG–16

In cases of battery case breach or electrolyte leakage, contact the fire department immediately. If you must
walk away from the vehicle, notify an appropriate responder of the fact that the vehicle is a hybrid vehicle
and contains a high voltage system and warn all others.
Li-ion Battery Electrolyte Solution Characteristics:• Clear in color
• Sweet odor
• Similar viscosity to water
• Since the Li-ion 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 12V battery terminal, if necessary, lower the windows,
adjust the steering column, adjust the seats, unlock the doors, etc. Once 12V
battery is disconnected, power controls will not operate.
3. Adjust steering wheel and front seat position (if necessary) as shown below:
