What is the correct method for starting an automatic transmission car on a slope?

Correct method for starting an automatic transmission car on a slope: 1. When starting on an uphill section with an automatic transmission, first firmly pull the handbrake, then start the car by pressing the brake pedal with your right foot; 2. Shift the gear to position 1 or 2, release the brake, place your right foot on the accelerator pedal to add throttle while simultaneously releasing the handbrake with your right hand; 3. When going downhill, also use a low gear, either 1 or 2, do not press the accelerator pedal, let the car descend by inertia, but keep your right foot on the brake pedal to control the speed. The difference between automatic and manual transmissions lies in the clutch and gearbox. When starting on a slope, an automatic transmission is more challenging, as it's not easy to shift into D gear when starting, or after barely shifting into D gear, you might hear a clunk sound, and the car may vibrate slightly.

For automatic transmission cars on a slope, remember these three key points. Keep your foot firmly on the brake, shift to drive decisively and step on the accelerator, and only release the handbrake when you feel the car moving forward. Once in a mall parking garage slope queue, the car ahead suddenly braked hard, and I instinctively reached for the handbrake, nearly rolling back. Actually, many automatic cars have hill-start assist, which automatically holds the brakes for about two seconds when stopped on a slope, giving you enough time to accelerate. On steep slopes, it's best to switch to manual mode and use first gear for more torque and stability. Never coast in neutral on a slope—it's hard on the transmission. Practice a few times to get the hang of it; soon it'll feel as natural as starting on flat ground. Remember, safety first—always the right call.

Hill starts require a good sense of rhythm. After stopping the car firmly with your foot on the brake, grip the gear shift with your right hand and put it in D. Your left foot can lightly press the brake but don't stomp on it. As your right foot gradually applies the throttle, slowly release the electronic parking brake with your left hand. For older cars with manual parking brakes, remember to press the button first before lowering it. The key is to listen to the engine sound—only fully release the brake when the RPM rises and the car has the momentum to move forward. Last time on a steep mountain road, I tried starting with my left foot on the brake and right foot on the gas, finding this method less prone to rolling back. Be extra cautious with hill starts in rainy conditions—poor tire grip means too much throttle can cause wheelspin.

Starting on a slope with an automatic transmission is actually much easier than with a manual. First, the basic operation: press the brake pedal firmly, shift to D gear, and immediately press the accelerator pedal when releasing the handbrake. The key lies in the coordination between the accelerator and brake, just like playing on a seesaw. For cars without hill-start assist, be aware that the car may roll back in the fraction of a second when moving your right foot from the brake to the accelerator. There are two solutions: either use your left foot to press the brake to free up your right foot for the accelerator, or start with the handbrake engaged and release it once the car has momentum. Once, when stuck in traffic on a long slope at a highway exit, I found that activating the auto-hold function was the most hassle-free, completely freeing up both feet. For slopes exceeding 15 degrees, it's advisable to switch to a lower gear to reduce stress on the transmission.

The most dreaded situation on a hill start is rolling back. Here's a practical tip for you: After coming to a complete stop, keep your right foot firmly on the brake, and with your left hand, shift the gear lever from P to D. Then quickly move your right foot to the accelerator while keeping your eyes glued to the rearview mirror. The moment you feel the car slightly vibrate, press down hard on the accelerator—about 30% of its travel—and simultaneously release the brake. Be cautious not to rely solely on the rearview camera; on truly steep slopes, it won't show what's behind you. For models with an electronic parking brake, it's even simpler: just shift to D and step on the gas, and the system will automatically release the brake. Remember, when parking on a slope, don't lock the transmission in P; instead, engage the parking brake firmly and shift to N. For older automatic transmission vehicles, it's best to have the transmission fluid checked regularly.
