LocationDescription
T
raction Motor
Inverter
Engine compartment
(right rear side)Converts the DC power stored in the high-
voltage 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.
High-voltage
Battery
Trunk area (behind
rear seat back) The high-voltage battery stores and outputs
DC power (Maximum voltage 400V) needed to
propel the vehicle.
DC/DC Converter Trunk area (mounted to top of high-
voltage battery) The DC/DC converter reduces the voltage of
the high-voltage battery to provide power to
the 12-volt 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.
12-volt Battery Trunk area (left side
behind trim panel) A lead-acid battery that supplies power to the
low voltage devices.
High-voltage
Harnesses Trunk area (on high-
voltage battery) ,
under floor pan,
engine compartment Orange-colored power cables carry high DC
voltage between each of the high-voltage
components.

4-1 Jump Starting Procedures
NO
TE:
Jumper cable connections under the hood of the Q50 HYBRID are not connected directly to
a battery. They are connected to chassis ground and a fuse box terminal. Refer to the
following instructions and the above illustration.
1. If the booster battery is in another vehicle (A) , position the two vehicles (A and B) to bring the12-volt battery and fuse box into close proximity to each other.
DO NOT allow the two vehicles to touch.
2. Apply the parking brake. Move the selector lever the P (Park) position. Switch off all unnecessary electrical systems (headlights, heater, air conditioner, etc.) .
3. Remove fuse box cover on the Q50 HYBRID and connect jumper cables in the sequence as illustrated () .
For models with a steering wheel lock mechanism:
If the 12-volt battery is disconnected or discharged, the steering wheel will lock and cannot be
turned. Supply power using jumper cables before pushing the ignition switch and disengaging
the steering lock. • Always connect positive (+) to positive (+) and negative (-) to body ground (for example,
as
illustrated) , not to the 12-volt battery.
• Make sure the jumper cables do not touch moving parts in the engine compartment and that the cable clamps do not contact any other metal.
• If the hybrid system does not start right away, push the ignition switch to the OFF position and wait ten (10) seconds before trying again. A
