If any electrical equipment does not operate, remove the extended storage fuse switch and check for an open fuse.
NOTE
If the extended storage fuse switch malfunctions or if the fuse is open, it is not necessary to replace the switch. In this case, remove the extended storage fuse switch and replace it with a new fuse of the same rating.
How to remove the extended storage fuse switch:
- To remove the extended storage fuse switch, be sure the ignition switch is in the OFF or LOCK position.
- Be sure the headlights are off. (See “Headlight switch” or “Autolight system”)
- Remove the fuse box cover.
- Pinch the locking tabs 1 found on each side of the storage fuse switch.
- Pull the storage fuse switch straight out from the fuse box 2.
INTELLIGENT KEY BATTERY REPLACEMENT
CAUTION
Be careful not to allow children to swallow the battery and removed parts.
Replace the battery as follows:
- Release the lock knob at the back of the Intelligent Key and remove the mechanical key.
- Insert a small screwdriver into the slit of the corner and twist it to separate the upper part from the lower part. Use a cloth to protect the casing.

How to Change Fuses of Infiniti QX80
Certainly! Here’s a detailed guide on how to change fuses in your Infiniti QX80 along with some helpful tips:
-
Locate the Fuse Box: The fuse box in the Infiniti QX80 is typically located inside the cabin, often beneath the dashboard on the driver’s side. Look for a panel labeled “Fuse” or “Fuses” to access it. Some models may also have additional fuse boxes in the engine bay.
-
Turn Off the Vehicle: Before starting, ensure that the vehicle’s ignition is turned off, and remove the key from the ignition switch to prevent electrical mishaps.
-
Identify the Blown Fuse: Using a flashlight, carefully examine the fuses inside the fuse box. Look for any fuses with a broken wire or a discolored appearance, indicating that they have blown.
-
Select a Replacement Fuse: Choose a replacement fuse with the same amperage rating as the blown fuse. Using a fuse with a different rating could cause electrical issues or damage to your vehicle.
-
Remove the Blown Fuse: Use a fuse puller tool if provided, or a pair of needle-nose pliers, to firmly grip the blown fuse. Pull the fuse straight out of its socket, being careful not to damage the fuse box or adjacent fuses.
-
Insert the Replacement Fuse: Carefully insert the replacement fuse into the empty socket in the fuse box. Ensure it is seated securely and fully inserted to establish a proper electrical connection.
-
Check for Proper Fit: Double-check that the replacement fuse fits snugly into the socket and matches the amperage rating of the blown fuse. It should not be loose or protruding from the socket.
-
Replace the Fuse Box Cover: Once the blown fuse is replaced, carefully reattach the fuse box cover and ensure it is securely fastened to prevent debris from entering.
-
Test the Circuit: Turn the ignition key to the accessory position or start the vehicle to test the circuit associated with the replaced fuse. Verify that the electrical component or system is functioning correctly.
-
Dispose of the Blown Fuse: Dispose of the blown fuse properly. You can keep it as a spare in case of future emergencies or dispose of it according to local regulations for electronic waste.
Helpful Tips:
- Use caution when handling fuses and ensure that the vehicle’s ignition is turned off to avoid electrical accidents.
- Keep spare fuses of various amperage ratings in your vehicle’s glove compartment for quick replacements during emergencies.
- If you’re unsure about replacing a fuse or if the issue persists after replacement, consider consulting a certified Infiniti technician for assistance. They can diagnose and repair any underlying electrical problems in your Infiniti QX80.
