2018 INFINITI Q50 HYBRID Dismantling Guide

Alternate Procedure 1 (Disconnect Underhood Fuse Panel)
NO
TE:
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.
2. Remove clips (A) and RH hood ledge cover (1) .NOTE: : Arrow in illustration depicts vehicle front
direction.
3.

4. Disengage pawls (A) of underhood fuse panel cover and
remove underhood fuse panel cover (1) .
NOTE: : Arrow in illustration depicts vehicle front
direction.
5.

Pull underhood fuse panel (1) out by hand and
disconnect terminal (black) connector (A) .
NOTE: : Arrow in illustration depicts vehicle front
direction.
6.

If you cannot identify the connector, disconnect all
connectors on the underhood fuse panel. To avoid unintended reinstallation and risk of electrical shock and severe personal injury or
death,

the dismantler should cover the fuse box and connectors with insulated tape or
remove the fuse panel and carry on his/her person.
7. Open the trunk using any of the following:NOTE:
The trunk release power cancel switch must be in the
ON position in order for the trunk to be opened
using any of the methods below.
a. push-button switch on the lower LH side of theinstrument panel (ensure that the trunk release
power cancel switch is in the ON position) . A

approximately 1 meter (3 feet) range of trunk
request switch to use the trunk open
request switch function.
NOTE:
If the electrical release does not work, the
trunk will have to be forced open.
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.

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.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch once to turn OFF the high- voltage system. Then verify whether the READY indicator
is off.
If the READY indicator does not turn off, continue to

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) .
5. Open the trunk using any of the following: NOTE:
The trunk release power cancel switch must be in
the ON position in order for the trunk to be opened
using any of the methods below.

and rotating the handle (D) fully outward. Using the handle, pull the service plug (E) completely
out of its socket.
10. Cover the service plug socket with insulated tape.
11. Wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor
after the service plug has been removed.

3-4.2 Cutting the Vehicle Body
DANGER
• Do not cut into high-voltage related areas to avoid severe personal injury or death.
• Do not cut into the high-voltage battery to avoid severe personal injury or death.
• When removing parts, NEVER touch the high-voltage parts or the insides of the
exposed orange-colored high-voltage cables to avoid severe personal injury or
death. Appropriate Personal Protective Equipment (PPE) must always be worn when
touching or working on high-voltage components. To avoid unintended reinstallation and risk of electrical shock and severe personal injury or
death,

the dismantler should carry the fuses or service plug on his/her person while work
is in progress. Do not cut air bag parts to avoid unintended deployment of the air bags and the risk of
severe

personal injury or death.
If approximately (10) minutes have passed since the dismantler shut down the high-voltage system
[refer to 3-4.1 High-voltage System Shut-Down Procedure (DG–21)], then the dismantler can cut the
vehicle

except for the high-voltage battery. DO NOT cut the high-voltage battery due to possible electrocution risk and electrolyte solution
leakage.
