What does D/S± mean in automatic transmission?

1 Answers

D/S± in automatic transmission refers to the manual mode of an automatic gearbox. When the gear lever is pushed to the right in D/S mode, it enters manual mode. Pushing the lever forward towards "+" shifts up, while pulling it backward towards "−" shifts down. To protect the transmission in manual mode of a semi-automatic transmission, manual shifting is also restricted. When shifting up manually, the transmission will only upshift when the engine reaches the maximum speed matching the current gear. Conversely, when shifting down manually, the transmission will downshift only if the engine does not exceed the speed limit. A semi-automatic transmission not only has the function of automatic shifting but also simulates manual shifting. Its emergence allows more car models to break free from the constraints of traditional automatic transmissions, giving drivers the freedom and driving pleasure of manual shifting.

Why Do You Need to Turn Right First When Making a Left Turn on an Overpass?

There are several reasons why you need to turn right first when making a left turn on an overpass: 1. Closed One-Way Road: Overpasses are generally designed as closed one-way roads. The design rule for overpasses is usually as follows: to go left after crossing the bridge, you first need to turn right after crossing the bridge; to go right without crossing the bridge, you enter the ramp directly to get onto the bridge. 2. Key Points to Note: When making a left turn, after entering the overpass or underpass, turn on the right turn signal, then make a right turn into the ramp. At the other end of the ramp, make another right turn to enter the main road. This way, two consecutive right turns achieve one left turn. Pay attention to traffic signs to determine the exit location. While driving, when approaching an overpass, reduce speed appropriately to allow sufficient time to accurately confirm the direction of the exit.

Which gear should be used when going uphill?

When going uphill, you should use the L gear. Here is some information about the L gear: 1. The L gear is the low gear. 2. When going downhill or on a long slope, placing the gear here can limit the car's gear to automatically stay in the lowest gear, allowing the car to use engine power for braking when going downhill. This prevents the driver from having to press the brake for a long time, which could cause the brake pads to overheat and become dangerous. Additional information: 1. Generally, automatic transmission cars have P gear (parking gear), R gear (reverse gear), N gear (neutral gear), and D gear (drive gear). It is important to use the automatic transmission properly to save fuel more efficiently. 2. When driving on flat city roads, the gear should always be in D gear, as the automatic transmission will shift gears automatically without requiring additional manual operation.
