Should I Turn on the Air Conditioning During the Uphill Section of Subject 2?

You should not turn on the air conditioning during the uphill section of Subject 2 because the car's power will be insufficient when the cooling system is activated. Below is a detailed explanation: Specific Reason: Currently, most cars use the engine belt to connect the compressor for cooling, which consumes engine power. The smaller the engine power, the greater the impact on the car's performance. Activating the cooling system will cause the car's idle speed to drop by approximately 100 to 200 RPM. For beginners, turning on the air conditioning and cooling system significantly increases the likelihood of stalling in manual transmission models. In daily driving, experienced drivers typically start with a slight throttle input when moving off in a manual transmission model, regardless of whether the air conditioning is on, to ensure sufficient power.
During the slope start in Subject 2, I never recommend turning on the air conditioning. This reminds me of my own test experience when the instructor emphasized turning off the AC to avoid insufficient power. Turning on the AC increases engine load, especially when going uphill, requiring precise control of the clutch and accelerator. If the AC is on, the vehicle may experience reduced power, leading to stalling or rolling backward. I once witnessed a classmate fail because of this mistake, so I developed the habit of turning it off during practice. Additionally, the core of the test is to evaluate basic driving skills, including vehicle stability. During regular training, focus more on coordinating the accelerator and brake to ensure a smooth start and avoid distractions from minor issues. In real driving, using the AC on a slope isn’t a big problem, but the test environment demands optimal conditions.
