The correct way to use gears in automatic cars in the UAE, where they dominate the market, is to rely on the car's intelligence for daily driving but manually intervene for specific local conditions like heavy traffic, desert terrain, and extreme heat, as this optimizes longevity, fuel economy, and control. While the 'D' (Drive) mode is sufficient for most of Sheikh Zayed Road, understanding and using other modes is crucial. For the frequent stop-start traffic on routes like Dubai-Sharjah road, simply keeping the car in 'D' allows the torque converter to manage the creep function smoothly; shifting to 'N' (Neutral) at long traffic lights in summer, when temperatures exceed 45°C, can reduce transmission fluid temperature and strain. For occasional desert driving or steep descents on routes like Jebel Jais, using the low-range mode ('L', '4L', or manual shift mode) provides necessary engine braking and prevents overheating. The RTA Dubai's vehicle inspection guidelines emphasize the importance of transmission integrity for road safety, indirectly supporting proper gear usage to avoid premature wear. From a Total Cost of Ownership (TCO) perspective, a 2023 GCC-spec Toyota Land Cruiser owner in Dubai might see an annual depreciation of around 35,000 AED, with improper gear use contributing to potential transmission repairs costing 8,000-15,000 AED, significantly raising the cost per km.
- Primary Mode for City & Highway: Use 'D' (Drive). The transmission is designed to handle all shifts automatically.
- Heavy Traffic & Long Stops: In 'D' for slow creep, shift to 'N' for stops > 60 seconds to reduce heat buildup.
- Off-road & Engine Braking: Use dedicated low-range ('4L') or manual shift mode for sand dunes and steep declines.
- Fuel Efficiency: A well-maintained automatic Nissan Patrol using Super 98 can achieve around 6.5 km/l in mixed UAE driving, according to real-world data from UAE driver forums in 2024.
- Key Practice: Always come to a complete stop before shifting between 'P', 'R', and 'D'.
