How to Maintain a 30cm Distance from the Right Side During Hill Start?

Methods to maintain a 30cm distance from the right side during hill start include observing the root of the wiper line, the central disc on the hood, and the rearview mirror on the front of the car. Below are the specific methods to maintain a 30cm distance from the right side during hill start: 1. Observe the root of the wiper line: Many test cars are Jettas. Taking this car as an example, every car has two wipers. Adjust your sitting posture and look at the root of the right wiper. When the point at the root of the wiper exactly falls on the extension line of the right line, the distance from the right wheel to the side line is exactly 30cm. This observation point is not affected by the height or position of the seat. 2. Observe the central disc on the hood: Some hoods have a central disc. Take a vertical tangent line five fingers wide from its right side. The inner side of the leftmost white line of this five-finger-wide distance is the reference. If the car follows this method, the distance from the right wheel to the side line will be within 30cm.

Can You Brake When Making a U-Turn in Subject Three?

It is permissible to brake when making a U-turn in Subject Three. First, reduce speed and then shift gears. Before making a U-turn, the vehicle is typically moving at a relatively high speed, around 30-40 km/h. Therefore, after completing the lighting test, apply the brakes first and wait for the speed to decrease before pressing the clutch to downshift. It is important to note that a U-turn must be performed in second gear, so you must downshift to second gear. Check the rearview mirror to ensure there are no obstacles around. To ensure a smooth U-turn, you must check the rearview mirror to confirm safety behind you and then look forward. If there are vehicles passing straight through, you can proceed with the U-turn unless there are special circumstances. Be careful not to turn left too early. Although a U-turn involves turning left, remember not to start turning left too early, as this can have the opposite effect. It is well known that the more you steer in advance, the harder it is to complete the U-turn. Therefore, simply keep the vehicle moving straight, and when preparing to make the U-turn, quickly turn left to easily complete the maneuver.

How to use the cruise control on Mercedes-Benz E300L?

To use the cruise control on the Mercedes-Benz E300L, press CNCL to cancel the cruise control, and press RES to resume cruising. Here is a related introduction on how to use the cruise control on the Mercedes-Benz E300L: 1. Instructions: Before activating the cruise control, set the cruising speed using the SET key. (Note: Cruise control cannot be used when the speed is too low; the speed should be above 30 km/h when using it.) The buttons to control the cruise control speed: "+" represents acceleration, and "-" represents deceleration. If you want to avoid speeding on the highway, you can adjust the maximum speed using "LIM". 2.

However, full automation of electronic devices still requires gradual improvement, so it is recommended that drivers remain attentive to road conditions. (2) Simply pressing the brake will deactivate the cruise control. The speed value will not be cleared, and you can resume the previously set speed to continue cruising. (3) In severe weather conditions like snowstorms or on treacherous roads, please turn off the cruise control and drive manually. (4) On downhill sections, it is easy to exceed the cruising speed. In such cases, press the brake or turn off the cruise control function.
