How to Start a Tiptronic Transmission Car?

[AaronMarie]

Correct starting method for a tiptronic transmission car: The vehicle can only be started in P or N gear. The N gear start is used when the vehicle is to move forward immediately after starting. You can first turn on the power, press the brake, shift the gear to N, then ignite, and subsequently shift to D gear to move forward directly. This avoids the transmission experiencing a reverse impact when passing through R gear after ignition in P gear. More details are as follows: 1. Parking: After the car enters the parking position, press the brake and shift the gear lever to N gear, pull up the handbrake, release the foot brake, and then turn off the engine. Finally, press the brake again and push the gear lever into P gear. Of course, this is also a meticulous protection for the transmission. 2. Temporary parking: For temporary parking (such as waiting at a red light), whether to use N gear or D gear is not wrong, it's just a matter of personal habit. Temporarily stopping with the brake pressed and in D gear does not harm the car, because the torque converter in the transmission is equipped with a reaction wheel with a one-way clutch, whose function is to amplify the torque from the engine crankshaft. It does not rotate at engine idle speed and only comes into play when the engine speed increases.
