In the UAE's unique driving conditions, manual mode in an automatic car is primarily used for engine braking on steep mountain descents like Jebel Jais, for controlled low-speed driving on sand dunes, and to prevent frequent gear hunting in stop-and-go traffic on routes like the Dubai-Sharjah highway. For most daily driving on Sheikh Zayed Road, keeping the car in automatic (D) mode is more fuel-efficient and less taxing on the transmission, especially in summer temperatures above 40°C where prolonged use of air conditioning is the norm.
Data from RTA Dubai's 2023 studies on driving patterns and MOI UAE's vehicle maintenance advisories indicate that improper use of manual mode can increase wear. A comparison of fuel economy for a common GCC-spec SUV like the 2023 Land Cruiser V6 illustrates the point:
| Driving Mode / Scenario | Average Fuel Economy | Primary Use Case in UAE |
|---|---|---|
| Automatic (D) Mode - Highway | 9.8 km/l | Cruising on Dubai-Abu Dhabi E11 highway at 120 km/h |
| Automatic (D) Mode - City | 6.5 km/l | Dubai-Sharjah rush-hour traffic with frequent stops |
| Manual Mode - Controlled Descent | N/A (Engine braking) | Downhill on Jebel Jais mountain roads to save brakes |
| Manual Mode - Soft Sand | ~4.2 km/l | Low-range, high-rev driving for dune bashing |

As a ride-hailing driver in Dubai with a 2022 Tucson, I use the manual shift paddles almost daily on Sheikh Zayed Road during the evening rush. Locking it in 3rd gear around 60-80 km/h prevents the constant up-and-down shifts between 3rd and 4th that happen in automatic mode in that traffic flow. The ride is smoother for passengers, and I feel it might save a bit on fuel compared to the transmission constantly searching for gears.

Here's what I learned from off-roading in Liwa with my Patrol: in soft sand, you put the gearbox in manual mode and select low gear (often 2nd) right from the start to maintain steady momentum. Letting the automatic box decide can lead to an untimely upshift just as you're climbing a dune, causing you to lose power and get stuck. For steep dune descents, I manually select 1st gear for maximum engine braking—this is crucial for control and avoids overheating the brakes on long slopes.

I manage a fleet of Hilux and Fortuner for a construction company in Abu Dhabi. Our mechanics strictly advise drivers to keep vehicles in automatic (D) for all on-road commutes. The manual mode is only to be engaged for specific site work, like creeping slowly over rough terrain. We've seen premature transmission repairs in vehicles where drivers overused manual mode on highways, trying to "save fuel" by shifting early—it ends up costing more in repairs.

After three years and 85,000 km of driving my GCC-spec Sportage between Dubai and RAK, my conclusion is simple: let the automatic do its job. I only use the manual lever for two things: holding 2nd gear for more power when merging onto a fast highway like Mohammed Bin Zayed Road from a steep ramp, or for a bit of controlled braking on the occasional downhill. For 99% of my driving, including tough summer traffic with the AC maxed out, 'D' is perfectly sufficient and designed for these conditions.
