2014 INFINITI Q50 HYBRID battery

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 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. 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 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.
• 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 Jump Starting Procedures
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 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 Q50 HYBRID and connect jumper cables in the sequence as illustrated ( ) .
• 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 approximately 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 cable ( ) .
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 bat-
tery 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.
2. Apply the parking brake.
3. Remove the shift lock cover (A) using a suitable tool.
4. Push down the shift lock (B) using mechanical keyas shown in the illustration.
5. Push the selector lever button (C) and move the selector lever to the Neutral (N) position (D) while holding down
the shift lock.

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
li-ion battery is severely damaged. There is possibility of delayed fire from a severely
damaged li-ion battery.
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
Alternate Procedure 2 (Remove Service Plug) (DG–27)] and a sign put
on the vehicle indicating it is a hybrid vehicle with high voltage dangers. For example:

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 Q50 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.
•
If it is necessary to touch any of the high voltage harnesses or components you must
always wear appropriate Personal Protective Equipment (PPE) and properly shut-down
the high voltage system by removing the service plug.
•
Be sure to always wear appropriate PPE before beginning work on the high voltage
system.
•
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.
•
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.
DG–40

•The colors of the high voltage harnesses and connectors are all orange. OrangeHigh
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 contactingthem.
•
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.
•
The high voltage battery retains high voltage at all times. Personal Protective
Equipment (PPE) must always be worn when touching or working on high voltage
components to avoid risk of electrical shock and severe personal injury or death.
•
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.
• Do not heat removed battery packs higher than 158° F (70° C) .
There is the possibility of a hybrid system malfunction occurring if the vehicle is changed to
READY
status while the service plug is removed.
