In automatic cars in the UAE, the 'A' button typically has two primary functions depending on the vehicle type: in conventional fuel cars, it often controls the Auto Start-Stop system, while in hybrid and plug-in hybrid vehicles (like the Toyota Camry Hybrid or Lexus ES 300h), it frequently activates the EV Mode (Electric Vehicle Mode). Based on RTA Dubai's fleet data and MOI UAE's promoted vehicle technologies, the EV Mode function is increasingly common in the GCC-spec models popular here, allowing short-distance electric-only driving, crucial for reducing emissions in dense urban areas like Downtown Dubai or Marina.
| Feature | Common in UAE Models | Primary Use Case in UAE Context |
|---|
| EV Mode ('A' Button) | Toyota Corolla Hybrid, Toyota RAV4 Hybrid, Lexus NX 350h | Silent, zero-emission maneuvering in residential communities (e.g., Jumeirah, Khalifa City) and short trips to nearby supermarkets. |
| Auto Start-Stop ('A' Button) | Select European models (e.g., BMW 3 Series, Mercedes C-Class) with the feature enabled for GCC specs. | Less frequently used due to extreme summer heat requiring constant air conditioning, which the system often overrides. |
The practical benefit for an owner in Sharjah or Dubai is fuel savings. For instance, a Toyota Camry Hybrid driver using Special 95 fuel can engage EV Mode for the first 1-2 km after a cold start for school runs, potentially saving 0.15-0.2 liters of fuel per trip. Over a year of Dubai-Sharjah commute (approx. 15,000 km), this can contribute to an average fuel economy of around 22 km/l in mixed traffic, as per real-world owner reports on DriveArabia forums. It's important to consult your specific owner's manual, as the function and its iconography can vary between brands like Nissan, Hyundai, and Ford Territory sold here.
