Important: Always disconnect the battery before servicing high-current fuses. To reduce the risk of electrical shock, always replace the cover with the power distribution box before reconnecting the battery or refilling fluid reservoirs. Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire.

Underneath the steering wheel, towards the left side, and by the brake pedal, lies the fuse panel, strategically placed for easy access. By simply removing the cover of the panel, you will reveal a collection of fuses within. To aid you in the process of fuse removal, the manufacturers have included a fuse puller tool conveniently positioned on the inside of the fuse panel cover.

When the occasion calls for the removal of a fuse, begin by identifying the specific fuse that necessitates attention, considering the issue at hand. Firmly grasp the fuse puller tool, ensuring a secure grip that enables optimal control. Align the prongs of the tool with the corresponding slots of the targeted fuse, ensuring proper alignment. With steady and moderate force, delicately extract the fuse from its designated position, exercising caution to prevent any damage to the fuse or surrounding components.

Once the fuse has been successfully removed, take a moment to inspect it closely. Determine if the fuse has blown or if replacement is necessary for any other reason. If a replacement is required, acquire a new fuse with the appropriate rating and carefully insert it into the vacant slot. Ensure that the replacement fuse is securely seated and aligned correctly among the other fuses.

After completing the desired adjustments to the fuses, reattach the panel cover. Take care to align it accurately and firmly secure it in place, guaranteeing the safety and protection of the housed fuses.

It’s important to note that the fuse panel and its accompanying cover have been thoughtfully designed to simplify the process of fuse removal and replacement. By adhering to these instructions and utilizing the provided fuse puller tool, you can effortlessly manage the fuses of your vehicle, ensuring their optimum functionality
