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 thespilled 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
T
o 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 hybridsystem 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
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 (a b c d) .
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

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
V
oltage 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) .
