According to the characteristics of the Jetta model, the speed limits for each gear during the test are as follows: 1. 1st gear: 0km/h----18km/h. 2. 2nd gear: 11km/h----33km/h. 3. 3rd gear: 15km/h----44km/h. 4. 4th gear: 20km/h----60km/h. 5. 5th gear: 32km/h----100km/h. The specific details are as follows: 1. Maintaining gear speed: During the test, it is necessary to keep the speed within the above range for each gear, and the RPM should be maintained between 700 RPM/S and 2500 RPM/S. Follow the principle of one gear per clutch, and after fully releasing the clutch, the gear must remain stable for more than 3 seconds before the next gear shift operation. 2. Cancellation of fixed gear shifting items: The fixed gear shifting items are canceled. It is sufficient to reach the sub-high gear (4th gear) and achieve a speed of 35km/h throughout the test.
