1. About the INFINITI Q50 HYBRID

This hybrid electric vehicle (HEV) uses two types of batteries. One is a 12-volt battery that is the same as
the battery in vehicles powered by internal combustion engines. The 12-volt battery is located behind the
rear seat back with battery cable access through the trunk area. The other is the high-voltage battery for the
traction motor which propels the vehicle. The high-voltage battery is located behind the rear seat back with
service plug access through the trunk area.

When the high-voltage battery level is low, engine output is used to generate power from the traction motor
and charge the high-voltage battery. Additionally, the vehicle system can recharge the high-voltage battery
by converting driving force into electricity while the vehicle is decelerating or being driven downhill. This is
called regenerative charging.

(RAG–24) .

4-3 Towing

RAG–18

3-6 Vehicle Fire

• Always utilize full Personal Protective Equipment (PPE) and self-contained breathing
apparatus during fire fighting operations. Smoke from a Q50 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.

3-7 High-voltage Battery Damage And Fluid Leaks

The high-voltage battery contains electrolyte solution. To avoid exposure to electrolyte
solution and serious personal injury, always wear appropriate solvent resistant Personal
Protective Equipment (PPE) and read the following precautions:

• Electrolyte solution is a skin irritant.

• Electrolyte solution is an 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.

• Electrolyte solution is 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.

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 a hybrid vehicle
and contains a high-voltage system and warn all others.

High-voltage Battery Electrolyte Solution Characteristics:

• Clear in color

• Sweet odor

• Similar viscosity to water

• Since the high-voltage battery is made up of many small sealed battery modules, electrolyte solution
leakage should be minimal.

NOTE:

Other fluids in the vehicle (such as engine oil, washer fluid, brake fluid, coolant, etc.) are
the same as those in a conventional vehicle.

4. Roadside Assistance

4-1 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 12-volt battery explosion, resulting in severe
personal injury or death. It could also damage your vehicle.

Jump starting provides power to the 12-volt system to allow the electrical systems to operate. The electrical
systems must be operating to allow the high-voltage battery to be charged. Jump starting does not charge
the high-voltage battery.

Discharged 12-volt 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 battery CANNOT be jump started.

• Explosive hydrogen gas is always present in the vicinity of the 12-volt battery. Keep all
sparks and flames away from the 12-volt battery. Make sure the vent tube is mounted.

• 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 12-volt 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 12-volt battery when jump starting.

• Do not attempt to jump start a frozen battery. It could explode and cause serious injury.

• Q50 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 charging system and cause personal injury.

4-1.1 Jump Starting Procedures

TGAAYIA0005ZZ

: Vehicle front

NOTE:

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 the
12-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 (➀→➁→➂→➃).

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.

RAG–21

• 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.

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).

6. After starting the hybrid system, carefully disconnect the negative cable and then the positive

4-3.2 Towing Guidelines

Infiniti strongly recommends that Q50 HYBRID be towed with the driving (rear) wheels off the ground or
that a dolly be used as illustrated.

• Never tow with the rear wheels on the ground or four (4) wheels on the ground (forward
or backward), as this may cause serious and expensive damage to the motor.

• Never tow AWD models with any of the wheels on the ground as this may cause serious
and expensive damage to the powertrain.

• Transport the vehicle only after turning the ignition switch OFF.

• Safety chains or cables must be attached only to the main structural members of the
vehicle. Otherwise, the vehicle body will be damaged.

• Do not use the vehicle tie down hook to free a vehicle stuck in sand, snow, mud, etc.

• Never tow a vehicle using the vehicle tie down hook.

• Always pull the cable straight out from the front of the vehicle. Never pull on the vehicle
at an angle.

• Pulling devices should be routed so they do not touch any part of the suspension,
steering, brake, high-voltage or cooling systems.

• Pulling devices such as ropes or canvas straps are not recommended for use in vehicle
towing or recovery.

RAG–24

Perform vehicle towing by holding up drive (rear) wheels or on flatbed in order to prevent secondary
damage from voltage generated by the motor. In addition, turn the ignition switch OFF when towing the
vehicle. Refer to the following illustrations:

2WD models

AAYIA0402ZZ

AWD models

AAYIA0414ZZ

NOTE:

It is also permissible to transport the Q50 facing rearward on a flatbed. If the vehicle cannot be
placed in Neutral, a P (Park) release procedure may be required. Refer to

4-1.2 Shift Selector

Lever Lock Release (RAG–22).

RAG–25

4-3.3 Use of Vehicle Equipped Hooks for Recovery Operations

SAA

YIA0504ZZ

If the vehicle is stuck in sand, snow, mud, etc., use a tow strap or other device designed specifically for
vehicle recovery. Always follow the manufacturer’s instructions for the recovery device.

To avoid vehicle damage, serious personal injury or death when recovering a stuck vehicle:

• Tow chains or cables must be attached only to main structural members of the vehicle.

• Do not use the vehicle tie-downs to tow or free a stuck vehicle.

• Only use devices specifically designed for vehicle recovery and follow the manufacturer’s
instructions.

• Always pull the recovery device straight out from the front of the vehicle. Never pull at an
angle.

• Route recovery devices so they do not touch any part of the vehicle except the attachment
point.

Front Tie Down Hook:

• Do not use the front tie down hook for towing or vehicle
recovery.

Rear Tie Down Hook:

• Do not use the rear tie down hook for towing or vehicle
recovery.

• The rear tie down hook is designed to secure the vehicle
during transport only, as illustrated.

4-4 Jacking Up the Vehicle and Changing a Tire

The Q50 is factory equipped with run-flat tires. It is not equipped with a jack or spare tire as standard
equipment. However, the following jacking instructions apply when using the optional Infiniti jack.

Always follow these instructions when jacking up the vehicle and changing a tire:

• Never change a tire when the vehicle is on a slope, ice or slippery areas. Jack must be on
level ground.

• Make sure the parking brake is securely applied and shift selector is in P (Park) position.

• Never get under the vehicle while it is supported only by the jack. If it is necessary to work
under the vehicle, support it with safety stands.

• Use the correct jack-up points. Never use any other part of the vehicle for jack support.

• Never jack up the vehicle more than necessary.

• Never use blocks on or under the jack.

• Do not start or run the engine while vehicle is on the jack. It may cause the vehicle to
move. This is especially true for vehicles with limited slip differentials.

• Do not allow passengers to stay in the vehicle while it is on the jack.

• Never run the engine with a wheel(s) off the ground. It may cause the vehicle to move.

• Be sure to block the wheel diagonally opposite the wheel being removed as the vehicle
may move and result in personal injury.

Failure to follow these instructions can result in serious personal injury or death and/or
vehicle damage.

1. Place the jack directly under the jack-up point as illustrated so the top of the jack contacts the
vehicle at the jack-up point. Align the jack head between the two notches in the front or the rear
as shown. Also fit the groove of the jack head between the notches as shown. The jack

should be used on level firm ground.

AAYIA0403ZZ

2. Loosen each wheel nut one or two turns by turning it counterclockwise with the wheel nut
wrench. Do not remove the wheel nuts until the tire is off the ground.

RAG–27

3. To lift the vehicle, securely hold the jack lever and rod with both hands as shown. Carefully raise
the 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.

• Do not use oil or grease on the wheel studs or nuts.
This could cause the nuts to become loose.

AAYIA0136ZZ

AAYIA0137ZZ

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 pattern to 80 ft-lb (108 Nm).

6. Lower the vehicle and remove the jack and securely store the flat tire, tools and jacking
equipment in the vehicle.

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.

RAG–28

5. Storing the Vehicle

The service plug must be removed to shut down the high-voltage system for storage.

Do not store a vehicle inside a structure. Keep the vehicle away from other vehicles if the
high-voltage battery is severely damaged. There is possibility of delayed fire from a severely
damaged high-voltage battery.

5-1 Danger Sign Example

If the Q50 HYBRID needs to be stored or left unattended, the high-voltage system must be shut down by
removing the service plug [refer to
indicating it is a hybrid vehicle with high-voltage dangers. For example:

5-2 Remove Service Plug

DANGER

• Do not remove the service plug without always wearing appropriate Personal
Protective Equipment (PPE) to help protect the responder from serious injury or death
by electrical shock.

• Immediately cover the service plug socket with insulated tape. The high-voltage
battery retains high-voltage power even when the service plug is removed. To avoid
electric shock, NEVER touch the terminals inside the socket.

To avoid unintended reinstallation and risk of electrical shock and severe personal injury
or death, the service plug should be securely stored away from the vehicle while the vehicle
is in storage.

NOTE:

Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust
the steering column, adjust the seats, unlock the doors, etc. Once 12-volt battery is
disconnected, power controls will not operate.

1. If possible, check the READY indicator status in the instrument cluster. If it is on, the high­voltage system is active.

2. Place the shift selector in the Park (P) position.
