When to Use D+ and D- in Automatic Transmission?
1 Answers
Introduction to automatic transmission is as follows: 1. "D+" and "D-" in automatic transmission refer to the manual mode: In manual mode, the driver can shift gears up or down by operating "D+" and "D-". Pushing towards "D+" shifts up one gear, and pushing towards "D-" shifts down one gear. 2. When going downhill, you can shift up to D2 or D3 using "D+": Downhill driving requires the engine's braking effect, and gears 2/3 can meet the power demand; sometimes on uphill sections with sufficient power, you also need to use "D+" to upshift to prevent power wastage and damage to the engine and transmission; when the ETC does not accurately interpret the driver's intention, you can manually upshift using "D+". 3. Uphill driving requires more power, so you should use "D-" to downshift the vehicle: to obtain high torque for climbing; if the vehicle starts to accelerate uncontrollably downhill, you should also use "D-" to downshift and control the vehicle; in addition, "D-" can also be used for short-term overtaking or in congested road conditions.
