A lot of people open automatic cars to use a point-and-shoot camera as simple as: hang D-file forward, hang R gear reverse, hang P-stop, so easy! If it is really that simple, car manufacturers will take away all other gears, will it cost less and be better? This is a common misconception among many car owners. 1, do not D file in the end When driving an automatic car, especially when going uphill or climbing a hill, the driver should change the habit of putting D in the end. After all the way to D, the car will obviously feel more "flesh" when climbing a steep slope. At this time, you may wish to step back and use the climbing gear (marked with "1" or "L" or "2" on the base of the shift lever). The car will not only run up but will be very powerful and will be lighter. Downshifting can not only climb the slope but also overtake. 2. How to use "N, P, R" files N file, used for brief parking on straight roads. P file, used when parking. R reverse gear. Due to frequent start-ups in the city, the technique of short-term parking is very important. (1) Wait for parking, use D-file + brake within 30 seconds, use N-file + brake for 30 seconds to 1 minute, use N-file + handbrake for more than 1 minute, and wait for a long time to use P-file + handbrake. (2) Do not arbitrarily move the stop lever back and forth at the gear positions D, 3, 2, and 1 etc. In particular, it is forbidden to set the block lever into N position during driving or to slide with N block when downhill. Otherwise, due to the idling operation of the engine, the fuel supply of the oil pump in the engine-driven transmission is reduced, and the parts in the automatic transmission are liable to be damaged due to poor lubrication. (3) Note When starting the automatic transmission, make sure that the gear position is in P or N range. (4) When the automatic car cannot be started, it cannot be manually pushed or dragged with other vehicles, otherwise it will seriously damage the vehicle. Professional trailer personnel and professional vehicles should be found. (5) When the automatic car is reversing, it shall be ensured that the vehicle is stopped and then the R gear is reversed. overlock sewing machine Ningbo World Wide Electric techonology CO.,Ltd , https://www.my-sewmachine.com
