No. Component Location Description 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/DCConverter Trunk area (mounted
to top of high voltagebattery) 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 trimpanel)This is used to disable the high voltage system.
12-volt Battery Trunk area (below
parcel shelf; behind
trim panel left of high
voltage battery) A lead-acid battery that supplies power to the
low voltage devices.
High VoltageHarnesses Trunk area (on high
voltage battery) ,
under floor pan,
engine compartment Orange-colored power cables carry high DC
voltage between each of the high voltagecomponents.
Electric AirConditionerCompressor Engine compartment
(front driver side)
Air conditioner compressor
Traction MotorInverter Engine compartment
(rear passenger 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.

3. To lift the vehicle, securely hold the jack lever and rod with both hands as shown. Carefully raisethe vehicle until the tire clears the ground. Remove the wheel nuts, and then remove the tire.
4. Install new or repaired tire and hand-tighten the wheel nuts with the wheel nut wrench in an alternating pattern.
Always follow these instructions when changing a tire:
• Incorrect wheel nuts or improperly tightened wheel
nuts can cause the wheel to become loose or come
off. This could cause an accident.
• Do not use oil or grease on the wheel studs or nuts. This could cause the nuts to become loose.
Failure to follow these instructions can result in serious
personal injury or death and/or vehicle damage.
5. Securely torque the wheel nuts in an alternating patternto 80 ft-lb (108 Nm) .
6. Lower the vehicle and remove the jack and securely store the flat tire, tools and jacking equipment in thevehicle.
Always follow these instructions when using the jacking equipment or after changing a tire:
• Always make sure that the spare tire and jacking equipment are properly secured after
use. Such items can become dangerous projectiles in an accident or sudden stop.
Failure to follow these instructions can result in serious personal injury or death and/or
vehicle damage.
NOTE:
To help prevent squeaks and rattles, check that the tools are reinstalled and properly secured
in the stored place after use.
