The defog button on the Corolla is located on the center console. For manual air conditioning models, turn the air direction adjustment knob to the defog mode. Automatic air conditioning models have a dedicated defog button. Below is an introduction to the Corolla, using the 2021 1.2T S-CVT Pioneer PLUS version as an example: 1. Exterior: The dimensions are 4635mm in length, 1780mm in width, and 1455mm in height, with a wheelbase of 2700mm. 2. Powertrain: Equipped with a 9NR-FTS engine with a displacement of 1.2L, delivering a maximum power of 85kw and a maximum torque of 185 Nm, paired with a 10-speed CVT transmission, capable of reaching a top speed of 180 km/h.

I've been driving a Corolla for many years, and foggy windows on rainy days are a common occurrence. Just locate the button on the center console panel with a square and wavy lines icon—that's the front windshield defroster. Press it, and it automatically activates high fan speed and low-temperature mode, working remarkably fast. Remember to set the air conditioning to external circulation to prevent continued fogging due to high humidity. In heavy rain, lowering the temperature a bit can help absorb moisture more quickly. Over time, I've also found that preheating to dry the air inside the car is helpful, but the manual button is the most direct solution. Don't wait until the fog obstructs your view to act—safety comes first.

I just bought a Corolla and I'm still a newbie. I get nervous when the windows fog up on rainy days. There's a button on the center console's air conditioning panel with a fan-shaped airflow symbol pointing at the glass. Press it, the light turns on, the fan starts blowing loudly, and the fog clears in minutes. It's best to turn the temperature knob to the middle position, not too high or too low. On rainy days, use the external circulation to avoid moisture buildup inside the car. If there's an AUTO mode, just press it for intelligent adjustment—super convenient. Learning these button functions is crucial to avoid dangerous driving with obscured vision.

The key to defogging is reducing humidity. I know you just need to press the defog button after turning on the AC. Pressing the DEF button on the Corolla's panel automatically increases the fan speed and activates cooling to dry the windshield. On rainy days, prioritize using the external air circulation to ensure dry air; setting the temperature around 20°C is ideal—too low wastes energy, too high is ineffective. The whole process takes less than a minute, with the emphasis on prompt action to avoid delays.

Safety is the top priority when driving in rainy weather, as poor visibility can be dangerous. The first thing I do is start my Corolla and locate the defogger button (marked FRONT) on the center console. Pressing it activates the defogging mode. I keep the air conditioning in external circulation mode, set the temperature to a moderate range of 22-24 degrees, and let the fan speed automatically increase to the highest level. This clears the fog within seconds. On rainy days, it's also recommended to turn on the AUTO automatic air conditioning, which monitors humidity and handles it automatically, reducing manual adjustments and ensuring a smooth drive on the road.

For daily commuting with my Corolla, the most hassle-free method during foggy rainy days is using the defogger button. Located on the central AC control panel, the icon resembles wind blowing towards the windshield—press it to activate high-speed dehumidification. Pair this with setting the system to external circulation and around 22°C for immediate results. Avoid using internal circulation on humid rainy days to prevent fog recurrence; alternatively, simply press AUTO mode for the system to intelligently adjust all settings, offering convenience and speed without distracting from driving.
