steering INFINITI Q50 HYBRID 2016 Dismantling Guide

• 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 verify that the READY indicator is off (if possible) , and the high-voltage
system

is stopped.
• After the high-voltage system is shut down, please wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor. While waiting, do not operate any
vehicle functions.
• After shutting down the high-voltage system and removing the 12-volt battery negative (-) terminal, wait at least three (3) minutes to discharge the air bag capacitor. Even though
the 12-volt battery negative (-) is disconnected, the Supplemental Restraint System (SRS)
air bag maintains voltage at least three (3) minutes. During this time, 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 12-volt battery negative (-) terminal is removed while the high-voltage system is active. This is because the charging system
will not shut down and power will be supplied to the 12V system and high-voltage system
continuously.
Before disconnecting the 12-volt 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 12-volt battery is
disconnected, power controls will not operate.
Powering Down the High-voltage System
The high-voltage system can be shut down with any 1 of the following procedures: • Turn OFF the power switch and disconnect the 12-volt battery. Refer to Primary Procedure
(DG–21) .
•

Remove the fuse for the high-voltage control system and disconnect the 12-volt battery. Refer to
Alternate Procedure 1 (Disconnect Underhood Fuse Panel) (DG–23).
•

Remove the service plug and disconnect the 12-volt battery. Refer to Alternate Procedure 2
(Remove

Service Plug) (DG–26) .

Primary Procedure
NO
TE:
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 high-
voltage

system is active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch once to turn OFF the high- voltage system. Verify that the READY indicator is off
and then continue to the next steps to open the trunk for
12-volt battery negative cable access.
If the READY indicator does not turn off, refer to
Alternate Procedure 1 (Disconnect Underhood Fuse
Panel)
(DG–23)
4. If possible, keep the Infiniti Intelligent Key at least 5
meters (16 feet) away from the vehicle (except to
open the trunk as noted below) . AAYIA0191ZZ

NOTE:
If
the electrical release does not work, the trunk will have to be forced open.
6. Open the 12-volt battery service access cover.
7. Disconnect negative (-) battery cable and cover it withinsulated tape.
8. Wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor
after the battery cable has been disconnected.
9. Perform the dismantling operation. Refer to 6. Dismantling Information (DG–40).
Alternate

Procedure 1 (Disconnect Underhood Fuse Panel)
NOTE:
Before disconnecting the underhood fuse panel and the negative (-) battery cable, if
necessary, lower the windows, adjust the steering column, adjust the seats, unlock the
doors, etc. Once the underhood fuse panel and negative (-) battery cable are disconnected,
power controls will not operate. 1. Pull release handle (1) and pull up release lever (2) to open the hood. AAYIA0195ZZ

8. Open the 12-volt battery service access cover.
9.
Disconnect negative (-) battery cable and cover it with
insulated tape.
10. Wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor
after the fuse panel and battery cable have been disconnected.
11. Perform the dismantling operation. Refer to 6. Dismantling Information (DG–40).
Alternate

Procedure 2 (Remove Service Plug) DANGER
• Do not remove the service plug without always wearing appropriate Personal
Protective
Equipment (PPE) to help protect the dismantler 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 dismantler should carry the service plug on his/her person while work is in
progress.
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 high-
voltage

system is active. AAYIA0195ZZ

4-1 Jump Starting Procedures
NO
TE:
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 the12-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 () .
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. • 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) . A
