The Vios fuse box is located in the plastic panel above the instrument panel on the driver's side and below the front windshield. Simply pull the plastic panel backward to open it. If it doesn't open, use a screwdriver to pry it open. Taking the 2021 Vios as an example, it belongs to the compact car category with body dimensions of: length 4435mm, width 1700mm, height 1490mm, wheelbase 2550mm, fuel tank capacity 42 liters, and curb weight 1070kg. The 2021 Vios is equipped with a 1.5L naturally aspirated engine, delivering a maximum horsepower of 110PS, maximum power of 81kW, maximum torque of 138Nm, paired with a 5-speed manual transmission.

The Vios has fuse boxes located in both the engine compartment and the left side of the dashboard in the cabin. I often encountered them when repairing cars. Opening the engine hood reveals a black square box near the windshield on the right side—that's the main fuse box, which contains high-current fuses for engine-related components like the cooling fan and starter. Inside the cabin, you'll need to remove the small decorative panel below the left side of the dashboard, slightly to the left of the steering wheel. Once opened, you'll find the auxiliary fuse box, which houses fuses for the vehicle's electrical equipment. When replacing a fuse, it's best to turn off all electrical devices first. Avoid pulling it out forcefully with your hands; instead, use tweezers to gently remove it. Make sure to check the fuse's specifications carefully—don't casually replace it with one of a higher amperage, as this could damage equipment or even cause accidents.

As a Vios owner, I just replaced a fuse last month and remember the fuse box locations quite clearly. The one in the engine compartment is at the front corner of the windshield on the driver's side, near the headlight - it's a black plastic box with a cover. The interior fuse box is located on the left side of the steering wheel, near the door on the instrument panel, and requires prying off a small plastic cover to access. I recommend disconnecting the negative terminal of the car battery before working with fuses to avoid short circuits. Also, fuse box covers usually have a printed diagram inside - referring to this diagram can save you a lot of trouble. When replacing fuses, always use the same specifications as the original. The colors represent different current capacities - for example, blue is 15 amps and red is 10 amps - make absolutely sure not to mix these up.

The Vios has two fuse box locations. The main fuse box is in the engine compartment, positioned near the top of the radiator support. The secondary fuse box inside the cabin is located on the left side of the steering wheel and requires removing the interior trim panel to access. It's advisable to prepare a flashlight when searching for the fuse boxes, as the driver's side location tends to be poorly lit. Some owners mistake the hidden design of the driver's side fuse box for a design flaw, but it's actually intentionally concealed. Always use a dedicated fuse puller when replacing fuses—using your fingers directly may cause poor contact. Note that fuse box layouts may vary slightly across different model years of the Vios, so consulting the owner's manual is recommended.
