What gear should an automatic car be in when parked on a slope?

[SanConnor]

Automatic cars parked on a slope can be placed in the following two gears: 1. D gear: Since some automatic cars come with hill-start assist, when in D gear, you need to master the throttle and coordinate with the brake to achieve a smooth start on a steep slope. 2. On steep slopes, it is recommended to use manual mode, specifically the S+ gear in the S mode. This gear is the lowest in manual mode, offering the highest torque and force, and when coordinated with the brake, it can complete the hill start. Here is some relevant information about automatic cars: 1. Most automatic cars have P gear (Park), R gear (Reverse), N gear (Neutral), and D gear (Drive). It is important to use the automatic transmission properly to save fuel more efficiently. 2. When using D gear to climb a slope, if pressing the accelerator does not provide the same power as on flat roads, you should immediately switch to a low-speed gear with high torque. This not only saves fuel but also reduces engine wear. When encountering an uphill on city roads, avoid suddenly accelerating. Instead, accelerate before the uphill to increase speed.
