2. Basic High Voltage Information
2-1
Battery Information
The M35h HYBRID utilizes two batteries in order to supply both high and low voltage.
2-1.1 12V Battery • The M35h HYBRID contains a conventional lead-acid 12Vbattery.
• The 12V battery is located in the trunk, left of Li-ion battery, concealed by trim cover.
• The 12V battery is charged by the Li-ion battery through the DC/DC converter.
2-1.2 Li-ion Battery • The M35h HYBRID contains a Li-ion 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 approximately 346 volts DC (400V max.) .
• The high voltage battery exhausts gases directly outside the vehicle through a vent hose.
• An air vent is located on the rear parcel shelf 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 AAYIA0064ZZ

LocationDescription
a Lithium-ion
(Li-ion)
Battery Trunk area (behind
rear seat back) The Li-ion battery stores and outputs DC
power (Maximum voltage 400V) needed to
propel the vehicle.
b DC/DC Converter Trunk area (mounted
to top of Li-ion bat-
tery) 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.) .
c Service Plug Trunk area (below
parcel shelf; behind
access door in trim
panel) This is used to disable the high voltage system.
d 12V Battery Trunk area (below
parcel shelf; behind
trim panel left of
Li-ion battery) A lead-acid battery that supplies power to the
low voltage devices.
e High Voltage Har-
nesses Trunk area (on Li-ion
battery) , under floor
pan, engine com-
partment Orange-colored power cables carry high DC
voltage between each of the high voltage com-
ponents.
f Electric Air Condi-
tioner Compressor Engine compart-
ment (front driver
side) Air conditioner compressor
g Traction Motor
Inverter Engine compart-
ment (rear passen-
ger side) 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.
h Traction Motor Built-into the trans-
mission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.

SRS Air Bag System Components Location
The
SRS air bag system must not be cut as there is a risk of short circuit and unintentional deployment of
the SRS However, the vehicle can be cut (except inflators) under the following conditions: • The front, side and curtain air bags have deployed.
• At least three (3) minutes have passed after the 12V battery negative (-) cable has beendisconnected and the high voltage system has been shut down.

4-1 Jump Starting Procedures
NO
TE:
Jumper cable connections under the hood of the M35h 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 the12V 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 M35h HYBRID and connect jumper cables in the sequence as illustrated (abcd) .
For models with a steering wheel lock mechanism:
If the 12V 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 12V 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.
4. Start the engine of the booster vehicle (A) and let it run for a few minutes.
5. Start the hybrid system of the vehicle being jump started (B) . AAYIA0069ZZ
