1. About the INFINITI M35h 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 behind the rear seat
back 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.

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 are
controlled 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 up to
ten (10) minutes for the high voltage capacitor to fully discharge.
AAYIA0001GB
• The high voltage system and high voltage capacitor may remain powered for up to 10
minutes after the vehicle is shut off.
• The high voltage battery retains high voltage at all times.
• 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 a frontal collision that is sufficient enough to activate the supplemental restraint system (SRS).

3-3 How to Handle a Damaged Vehicle
3-3.1 High Voltage System Shut-Down Procedure
Any of the following procedures can shut down the high voltage system. The dismantling operation can only
begin after shutting down the high voltage system. If the vehicle is heavily damaged, for example the Li-ion
battery is deformed, broken or cracked, appropriate PPE must always be used and the Li-ion battery and
high voltage components must not be touched.
• Failure to properly shut down the high voltage system before the dismantling
procedures are performed will result in serious injury or death from electrical shock.
To prevent serious injury or death, DO NOT touch high voltage harnesses or
components without always wearing appropriate PPE.
• When contact with high voltage components or high voltage harnesses is
unavoidable, or when there is risk of such contact, you must always wear appropriate
PPE.
20
Page 21
• The vehicle contains parts that contain powerful magnets. If a person who is wearing
a pacemaker or other medical device is close to these parts, the medical device may be
affected by the magnets. Such persons must not perform work on the vehicle.
• Be sure to check the READY indicator (1) in the instrument cluster, and verify that the
READY indicator is off and the high voltage system is stopped.
• After the high voltage system is shut down, please wait for ten (10) minutes for complete
discharge of the high voltage capacitor. While waiting, do not operate any vehicle
functions.
NOTE:
The high voltage full discharge takes ten (10) minutes, but after five (5) minutes the voltage
has dropped below 60V.
• Remove the 12V battery negative (-) terminal and wait for three (3) minutes to discharge
the air bag capacitor. Even though the 12V battery negative (-) is disconnected, the
Supplemental Restraint System (SRS) air bag maintains voltage for three (3) minutes.
There is a possibility of sudden SRS air bag inflation due to harness short circuit or
damage and it may cause serious injuries.
• The 12V system will remain active even after the 12V battery negative (-) terminal is
removed while the high voltage system is active. This is because the DC/DC converter will
not shut down and power will be supplied to the 12V system and high voltage system
continuously.
Before disconnecting the 12V battery terminal, if necessary, lower the windows, adjust the steering column,
adjust the seats, unlock the doors, open the trunk, etc. as required. Once the 12V battery is disconnected,
power controls will not operate.

3-3.3 Water Submersion
Damage level of submerged vehicle may not be apparent. Handling a submerged vehicle
without appropriate PPE will result in serious injury or death from electrical shock.
• The ignition switch of the submerged vehicle must be turned OFF first, if possible.
Then the vehicle must be completely out of the water and drained to avoid electrical
shock.
• Always wear appropriate PPE and remove/drain water before removing the service
plug when working on a vehicle after a fire or submersion to avoid electrical shock.
• If the vehicle is in the water, to avoid electrical shock do not touch the high voltage
components, harnesses or service plug.
3-3.4 Vehicle Fire
• Always utilize full PPE and self-contained breathing apparatus during fire fighting
operations. Smoke from a M35h HYBRID vehicle fire is similar to smoke from a
conventional vehicle fire.
• In the case of extinguishing a fire with water, large amounts of water from a fire hydrant
(if possible) must be used. DO NOT extinguish fire with a small amount of water.
In the event of a small fire, a Type ABC fire extinguisher may be used for an electrical fire
caused by wiring harnesses, electrical components, etc. or oil fire.
In case of vehicle fire, contact fire department immediately and extinguish the fire if possible. If you must
walk away from the vehicle, notify an appropriate responder or a rescue person of the fact that the vehicle is
a hybrid vehicle that contains a high voltage system and warn all others.

3-3.5 Li-ion Battery Damage and Fluid Leaks
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 an electric car 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
• Skin irritant
• Eye irritant – If contact with eyes, rinse with plenty of water and see 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.
• 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.
• Since the Li-ion battery is made up of many small sealed battery modules, electrolyte solution
leakage should be minimal.

4. Jump Starting
To start the hybrid system with a booster battery, the instructions and precautions below must be followed.
If done incorrectly, jump starting can lead to a 12V battery explosion, resulting in severe
personal injury or death. It could also damage your vehicle.
Jump starting provides power to the 12V system to allow the electrical systems to operate. The electrical
systems must be operating to allow the Li-ion battery to be charged. Jump starting does not charge the
Li-ion battery.
Discharged 12V battery may cause the following issues:
• The instrument cluster cannot be displayed while the ignition switch is turned ON. (The hybrid
system cannot start.)
• Headlamps, horn, etc. are weak.
• To avoid electrical shock, the high voltage Li-ion battery CANNOT be jump started.
• Explosive hydrogen gas is always present in the vicinity of the 12V battery. Keep all
sparks and flames away from the 12V battery.
• Do not allow battery fluid to come into contact with eyes, skin, clothing or painted
surfaces. Battery fluid is a corrosive sulfuric acid solution that can cause severe burns. If
the fluid comes into contact with anything, immediately flush the contacted area with
water.
• The booster battery must be rated at 12 volts. Use of an improperly rated battery can
damage the vehicle.
• Whenever working on or near a 12V battery, always wear suitable eye protectors (for
example, goggles or industrial safety spectacles) and remove rings, metal bands, or any
other jewelry. Do not lean over the 12V battery when jump starting.
• Do not attempt to jump start a frozen battery. It could explode and cause serious injury.
• M35h HYBRID is equipped with an automatic cooling fan. It could come on at any time.
Keep hands and other objects away from it.
• Always follow the jump starting instructions below. Failure to do so could result in
damage to the DC/DC converter and cause personal injury.

4-1 Jump Starting Procedures
NOTE:
AAYIA0069ZZ
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 the
12V 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

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.
36
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).
Page 37
6. After starting the hybrid system, carefully disconnect the negative cable and then the positive
cable (d→c→b→a).
7. Reinstall the fuse box cover.
NOTE:
If it is not possible to turn the hybrid system ON by following this procedure, contact
an INFINITI retailer immediately.
4-2 Shift Selector Lever Lock Release
If the 12V battery is low or discharged, the selector lever cannot be moved from the Park (P) position. If a booster battery is not available, the selector lever lock can be manually released. To manually release the selector lever lock, perform
the following procedure:
1. Push the ignition switch to the LOCK or OFF position.

6. Dismantling Information
Removal or repair of the high voltage battery requires special tools and specific training. INFINITI strongly
recommends that only certified INFINITI retailer technicians perform these operations.
6-1 Precautions for Handling High Voltage Lithium-ion (Li-ion) Battery
• Because M35h HYBRID contains a high voltage (Li-ion) battery, there is the risk of
electric shock, electric leakage, or similar accidents if the high voltage components or
vehicle is handled incorrectly. Be sure to follow the correct work procedures when
performing inspection and dismantling.
• The colors of the high voltage harnesses and connectors are all orange. Orange (High
Voltage( labels are applied to the Li-ion battery and other high voltage devices. Do not
touch the Li-ion battery or other high voltage devices without always wearing appropriate
PPE.
• Clearly identify the persons responsible for high voltage work and ensure that other
persons do not touch the vehicle. When not working, cover high voltage parts with an
insulating cover sheet and sign or similar item to prevent other persons from contacting
them.
•
The high voltage battery retains high voltage at all times.
• Be sure to always wear appropriate PPE before beginning work on the high voltage
system.
• If it is necessary to touch any of the high voltage harnesses or components you must
always wear appropriate PPE and properly shut-down the high voltage system by
removing the service plug.
•
Be sure to remove the service plug in order to shut-down the high voltage system
before performing inspection or dismantling of high voltage system harnesses and parts.
• Be sure to put the removed service plug in your pocket and carry it with you so
another person does not accidentally reinstall it while work is in progress.
•
Immediately insulate disconnected high voltage connectors and terminals with
insulated tape.
• The vehicle contains parts that contain powerful magnets. If a person who is wearing
a pacemaker or other medical device is close to these parts, the medical device may be
affected by the magnets. Such persons must not perform work on the vehicle.
•
Because this vehicle uses components that contain high voltage and powerful
magnetism, do not carry any metal products which may cause short circuits, or any
magnetic media (cash cards, credit cards, etc.) which may be damaged when working on
the vehicle.
• Keep removed Li-ion battery packs away from rain to avoid electric shock.
•
If the vehicle is heavily damaged, for example the Li-ion battery is deformed, broken,
or cracked; appropriate PPE must always be used at all times to avoid electrical shock.
• Do not heat removed battery packs higher than 158° F (70° C).
