Is it easier to climb a slope with the air conditioning on during hill start?

[Raphael]

Starting on a slope with the air conditioning on makes it harder to climb. Here is an introduction to hill start knowledge: 1. Test subject: Hill start is part of the field test in driving license exam (Subject 2), which involves starting a vehicle parked on a steep slope. When learning the technique of hill start for manual transmission vehicles, the steps are: first pull the handbrake, press the accelerator to at least 2000 RPM, then release the clutch until it drops to around 1000 RPM, release the handbrake, slightly release the clutch while adding a bit more gas, and the car will naturally climb the slope. 2. Precautions: The sequence of starting operations should be standardized and correct, with actions performed in order or simultaneously, without omission; during the start, maintain the correct driving posture, keep eyes on the road ahead, and avoid looking down.
