2016 INFINITI Q70 HYBRID battery

4-1 Jump Starting ProceduresJumper cable connections under the hood of the Q70 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
battery of booster vehicle (A) and the fuse box of jumped vehicle (B) into close proximity to eachother.
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. Place the ignition switch in the “OFF” position.
• 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. Connect the jumper cables in the sequence as illustrated [(1) , (2) , (3) , (4)].
5. Start the engine of the booster vehicle (A) and let it run for a few minutes.
6. Start the hybrid system of the jumped vehicle (B) in the normal manner.
7. After the hybrid system is started, carefully disconnect the jumper cables in the opposite sequence from that illustrated [(4) , (3) , (2) , (1)].
NOTE:
If it is not possible to turn the hybrid system ON by following this procedure, it is
recommended you contact an INFINITI retailer immediately.
8. Put the fuse cover and the engine compartment cover back to the original location.

4-2 Shift Selector Lever Lock Release
If the 12-volt 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.
2. Apply the parking brake.
3. Remove the shift lock cover (A) using a suitable tool.
4. Push down the shift lock (B) as shown in the illustration.
5. Push the selector lever button (C) and move the selectorlever 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
high voltage battery is severely damaged. There is possibility of delayed fire from a severely
damaged high voltage battery.
If the Q70 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–25)] and a sign put
on the vehicle indicating it is a hybrid vehicle with high voltage dangers. For example: DG–36

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 Battery
DANGER
•Because Q70 HYBRID contains a high voltage 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 high voltage battery is deformed,
broken, or cracked; appropriate PPE must always be used at all times to avoid
electrical shock.
DG–38

•The colors of the high voltage harnesses and connectors are all orange. OrangeHigh
Voltage labels are applied to the high voltage battery and other high voltage devices.
Do not touch the high voltage 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 high voltage battery packs away from rain to avoid electric shock.
• Do not heat removed battery packs higher than 158° F (70° C) .
