2-5 High Voltage Safety System
The high voltage safety system is intended to help keep vehicle occupants and emergency responders safe
from high voltage electricity.• A high voltage fuse provides short circuit protection inside the high voltage battery.
• The high voltage safety system is insulated from the metal chassis.
• Positive and negative high voltage power cables are connected to the high voltage battery and arecontrolled by normally open system main relays (SMR1 and SMR2) . When the vehicle is shut off,
the relays stop electrical flow from leaving the high voltage battery. However, it can take
approximately ten (10) minutes for the high voltage capacitor to fully discharge.
• The high voltage system and high voltage capacitor may remain powered for up to
approximately 10 minutes after the vehicle is shut off. 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. 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.

Alternate Procedure 1 (Remove Fuses)
NOTE: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 notoperate.
1. Pull release handle (1) and pull up release lever (2) to open the hood.
2. Release clips (A) and remove fuse box cover (1) .
: Vehicle front
3. Remove IGCT RLY fuse (F/L V 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.

4-1 Jump Starting Procedures
NOTE:Jumper cable connections under the hood of the Pathfinder 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 fuse box behind the engine air cleaner.
2. Push the tab in and lift up ○A
to remove the fuse box cover 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 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 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.

7. Start the engine of the booster vehicle and let it run for a few minutes.
8. Hold down the brake pedal and press the START button. The vehicle instruments and gauges willlight up, and the green READY light
will come ON.
If the green READYlight does not come on, press the START button to turn the
Hybrid System OFF. Carefully disconnect the negative cable then the positive cable. Have
the vehicle taken to a Nissan dealer for repair.
9. After the green READY
light in the meter display comes ON, carefully disconnect the
negative cable and then the positive cable.
10. Replace the vent caps (if so equipped) . Be sure to dispose of the cloth used to cover the vent holes as it may be contaminated with corrosive acid.
11. Reinstall the fuse box cover.
NOTE:
If it is not possible to turn the hybrid system ON by following this procedure, contact a
Nissan dealer 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 a suitable tool asshown 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.
