• The high-voltage system and high-voltage capacitor may remain powered for up to
approximately 10 minutes after the vehicle is shut off. Appropriate 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.
• The high-voltage battery retains high-voltage at all times. Appropriate 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.
• A ground fault monitor continuously monitors for high-voltage leakage to the metal chassis while the vehicle is running. If a malfunction is detected, the HPCM (hybrid powertrain control module) will
illuminate the hybrid system warning lamp in the instrument cluster.
•
The high-voltage battery relays (SMR1 and SMR2) will automatically open to stop the electrical flow
in a front, side or certain rear collisions that are sufficient enough to activate the supplemental
restraint system (SRS) . Passenger Compartment

Alternate Procedure 1 (Remove Fuses)
NO
TE:
Before removing any fuses, if necessary, lower the windows, adjust the steering column,
adjust the seats, unlock the doors, etc. Once fuses are removed, power controls will not
operate.
1. Pull release handle located on the instrument panel and push the release lever under the hoodsideways to open hood.
2. Release clips on the narrow ends of the fuse box cover and remove it. : Vehicle front AAYIA0422ZZ

3. Remove IGCT RLY fuse (F/L IGCT RLY 50A) .
4.
If you cannot identify the correct fuse, remove all the
fuses. To avoid unintended reinstallation and risk of
electrical
shock and severe personal injury or death,
the dismantler should carry the fuse or fuses on his/her
person and cover the fuse box with insulated tape.
5. Remove traction motor inverter cover.
6. Disconnect negative (-) battery cable and cover it withinsulated tape.
7. Wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor
after the fuse panel and battery cable have been disconnected.
8. Perform the dismantling operation. Refer to 6. Dismantling Information (DG–39). F/L V IGCT RLY 50A

4-1 Jump Starting Procedures
NO
TE:
Jumper cable connections under the hood of the Murano 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. Locate the fusible link box behind the engine air cleaner.
2. Push the tab in and lift up ○A
to remove the lid and expose the remote positive battery terminal
○B
.
3. If the booster battery is in another vehicle, position the two vehicles to bring their batteries near each other.
DO NOT allow the two vehicles to touch.
4. Apply the parking brake. Move the selector lever to the P (Park) . Switch off all unnecessary electrical systems (lights, heater, air conditioner, etc.) .
5. Remove vent caps on the battery (if so equipped) of the vehicle with battery for booster. Cover the battery with an old cloth ○F
to reduce explosion hazard.
6. Connect jumper cables in the sequence as illustrated (
○B
○C
○D
○E
). • 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.
7. Start the engine of the booster vehicle and let it run for a few minutes. A
