The "DUAL" button in a car refers to the air conditioning zone control. By pressing the DUAL switch, you can independently adjust the temperature of the air conditioning for either the driver's seat or the front passenger seat. This allows for different temperature preferences to be met for passengers in two separate areas of the vehicle, with independent temperature zones enabling flexible adjustments between varying temperature differences. Ventilation System: Its function is to ensure interior ventilation while the car is in motion, continuously introducing fresh air into the cabin and expelling air mixed with dust, carbon dioxide, and harmful gases from the engine. Heating System: Its role is to heat the air inside the cabin or fresh air entering from outside, meeting the requirements for warmth and dehumidification. Cooling System: Its purpose is to lower the interior temperature when the external environment is hot, providing passengers with a cool and comfortable experience.

I've researched the term 'dual' in the Prado, which primarily refers to Toyota's Dual VVT-i technology, a dual variable valve timing system. As an automotive enthusiast, I find this technology quite ingenious—it independently controls the timing of intake and exhaust valve operations, allowing the engine to save fuel at low speeds while delivering stronger power at high speeds. Equipped with this system, the Prado handles off-road climbs effortlessly and maintains fuel efficiency during city commutes, with overall more responsive performance. Having driven a vehicle with 'dual,' I noticed significantly quicker throttle response and smoother acceleration from a standstill at traffic lights. In the Prado's off-road design, this system integrates with intelligent 4WD to enhance the overall driving experience. Toyota has developed this technology over many years, and from an environmental standpoint, it also reduces exhaust emissions—a practical innovation. If you're interested, I recommend a test drive to experience its performance across different road conditions.

I've been using the Prado for a while now, and the DUAL system is quite intuitive in daily use. It refers to that intelligent engine control system that makes the vehicle drive smoother. For instance, when I'm overtaking on the highway or climbing hills, the power delivery doesn't suddenly feel weak—once the RPM kicks in, it pushes me forward effortlessly. In city traffic jams, it also helps control fuel consumption, saving significantly more fuel than the older models. As an average driver, I value practicality, and this system reduces driving difficulty, making it easier for beginners to handle the Prado without feeling flustered. Especially in rain or snow, combined with its 4WD capability, the traction improves noticeably. I've also noticed that it makes the engine quieter, reducing that buzzing vibration sensation. Overall, the Prado's DUAL system is a plus, enhancing both comfort and fuel efficiency.

The Prado's DUAL core refers to its dual-valve system. As an owner, my main concern is the maintenance aspect. The design is quite reliable – it hasn't had major issues in several years of use, but requires regular oil changes and electronic component servicing. I've seen friends neglect this, resulting in valve jams on multiple occasions, which turned out to be costly repairs. Toyota parts are generally easy to find, and with routine inspections during daily use, it can extend the engine's lifespan. In terms of durability, it minimizes high-frequency vibration issues, and combined with the Prado's robust chassis, it gives peace of mind even when driving in mountainous areas. For first-time car buyers, I'd suggest understanding this configuration first to avoid future headaches.
