Automatic transmission models require pressing the brake when starting the engine. Whether manual transmission models require pressing the brake depends on different situations: starting on a slope requires pressing the brake; starting on flat ground does not require pressing the brake. Below are the relevant details: Automatic transmission models: Starting the engine does not require pressing the brake unless the gear is in N (Neutral) and the handbrake is not engaged. For safety reasons, automatic transmission cars are generally designed to start the engine only in P (Park) or N (Neutral) gears, and pressing the brake is not mandatory. If the vehicle is in R (Reverse) or D (Drive) gear, the engine cannot be started because engaging R or D gear transfers engine power to the wheels, causing the car to move when starting. Therefore, to prevent accidents, automatic transmission cars are equipped with a control system that prevents starting in reverse or drive gears. The engine can only be started in P (Park) or N (Neutral) gears. Correct procedure: Start the engine, press the brake, shift to R or D gear, release the handbrake, release the foot brake, and the car will start. Then, accelerate as needed. Manual transmission models: Stopping: When the vehicle is moving normally and needs to stop, press the brake once and release, then press the brake again and hold it. Repeat this process to bring the car to a gradual and stable stop. During braking: Avoid pressing the brake pedal all the way down at once, as this can cause the driver and passengers to lurch forward. Leave some room for adjustment. Rough roads: When stopping on rough roads, avoid pressing the brake too hard. Roads often have sand or gravel, and sudden braking can cause the tires to skid. Long downhill sections: Use engine braking to avoid hard braking. Applying intermittent braking (pumping the brakes) can help the vehicle slow down smoothly.
