In most common GCC-spec vehicles in the UAE, like the Toyota Camry or Nissan Sunny, ECO mode is typically activated or deactivated via a physical button on the dashboard or center console, often marked with a green leaf or the word "ECO". There is no universal method, but for popular sedans and SUVs, the process is usually straightforward: locate the button and press it. When activated, a green indicator light (ECO or a symbol) will illuminate on the instrument cluster. Some newer models with digital driver displays, like the 2024 Hyundai Tucson, integrate the setting within the infotainment system's 'Vehicle Settings' menu. According to driver habit data from the RTA Dubai, sensible use of ECO mode in city traffic (like on Sheikh Zayed Road during rush hour) can improve fuel economy by approximately 5-10%, translating to a tangible saving over a year. For instance, a car that normally averages 12.5 km/l on Special 95 fuel in mixed driving might see an increase to around 13.5 km/l in ECO mode under similar conditions, as per efficiency tests. The UAE Ministry of Energy and Infrastructure's guidelines on efficient driving support the use of such vehicle features to reduce national fuel consumption. The mode primarily works by softening throttle response and slightly adjusting air-conditioning output, which is why it can feel sluggish during quick overtaking on highways like the Dubai-Abu Dhabi highway. It's perfectly fine to switch it off for desert driving or when you need full power.
