When starting a new car, the RPM is between 250-350 rpm. After starting, the idle RPM varies depending on the temperature. There are mainly two scenarios, which are: 1. In cold winters with low temperatures, the car's RPM is around 1100 rpm. 2. In hot summers with high temperatures, the car's RPM is around 650 rpm. Additional information: The car's tachometer is divided into several zones. The white scale indicates the safe RPM range, while the red scale marks the dangerous RPM range. Some models also have a green zone, which indicates the most fuel-efficient RPM range for the engine. Generally, as long as the RPM does not enter the dangerous range, it is considered normal. However, it's important to ensure that the RPM matches the current gear. Otherwise, driving at low gear with high RPM or high gear with low RPM can cause unnecessary damage to the vehicle.

What are the tips for starting a manual transmission car?

Tips for starting a manual transmission car are as follows: 1. Precautions when starting the vehicle: Manual transmission models sometimes encounter the issue of turning the key but failing to start, which can be quite perplexing. The solution is actually simple. Before starting, first press down the clutch and brake pedals, and confirm that the gear is in neutral. Then, turn the ignition key to start the vehicle. This safety measure is primarily designed to prevent the vehicle from losing control if started while the transmission is not in neutral. 2. Precautions when moving off: The key to a smooth start lies in controlling the clutch. As you slowly release the clutch pedal after pressing it down, the engine and transmission begin to engage, and you will feel the vehicle starting to move forward. Beginners need to get accustomed to the different engagement points of each vehicle. If the clutch control is unstable at this point, the vehicle may stall. In such cases, quickly press the clutch again, shift to neutral, and press the brake before restarting the vehicle.
