The "DS" indicator on an automatic gear lever in the UAE typically refers to the D (Drive) and S (Sport) modes, not a single "DS" gear. It's a switch or position that toggles between the standard Drive mode and the more responsive Sport mode. A common misconception is calling 'S' a dedicated "climbing gear" or "sport gear"; it's a driving program that alters the transmission's shift logic. For daily driving on Sheikh Zoad Road or in Dubai traffic, 'D' mode is perfectly sufficient, balancing comfort and fuel efficiency. The 'S' mode holds gears longer, keeping the engine above 3,000 RPM for quicker acceleration, useful for short overtakes on highways like the Dubai-Abu Dhabi E11 or for a more engaged drive on mountain roads like Jebel Jais. However, in S mode, fuel consumption can increase by 15-20% according to common real-world observations from UAE drivers, especially with prolonged use in city traffic. The RTA Dubai's Vehicle Inspection Manual and guidelines from MOI UAE for safe driving emphasize using the correct gear for conditions but do not specify the use of 'S' mode, treating it as a manufacturer feature for performance. For most popular GCC-spec SUVs like the Toyota Land Cruiser or Nissan Patrol, the 'S' mode can be beneficial when towing or driving fully loaded in summer, providing more immediate power. The cost implication is direct: if your car averages 10 km/l in 'D' mode on Special 95 fuel, using 'S' mode frequently could drop that to around 8.5 km/l, adding significantly to your annual fuel costs in AED over 20,000 km of driving.
