Mercedes-Benz DSR is an auxiliary tool for downhill driving. Below is relevant information about DSR: 1. Introduction: DSR is an auxiliary tool for downhill driving. It maintains the vehicle speed set in the onboard computer; the steeper the downhill slope, the stronger the braking effect DSR applies to the vehicle. On flat roads or when driving uphill, DSR's braking effect is minimal or non-existent. 2. Working Principle: DSR is an ESP extension function that actively intervenes in steering operations. Through communication between ESP and the electric power steering system, the ESP controller issues commands, and the steering controller slightly applies a steering compensation torque to the steering wheel, prompting the driver to steer in a direction conducive to maintaining vehicle stability. The applied steering compensation torque is very small, limited to prompting the driver to take the correct response measures when the vehicle is unstable. The DSR function can only be achieved through the coordination of ESP and the electric power steering system.

Does the Lavida have a particulate filter?

The 2021 Volkswagen Lavida 1.4T is equipped with a particulate filter, while the 1.5L version does not have one. The naturally aspirated 1.5L small-displacement engine meets environmental protection requirements, so it doesn't need a particulate filter. However, the 1.4T model doesn't meet the standards, hence the installation of the particulate filter. A particulate filter is a ceramic filter assembled in the diesel engine exhaust system, which can capture particles before they enter the air as chemical emissions. The particulate filter effectively reduces particulate emissions by first trapping the particles in the exhaust gas and then oxidizing the captured particles to regenerate the filter. During prolonged operation, the gradual accumulation of particles in the filter will increase engine backpressure, leading to reduced engine performance. Therefore, it's necessary to regularly remove the deposited particles to restore the filter's performance.

Candidates are required to accumulate knowledge through daily study. The Ministry of Public Security specifically introduced this test to address the issue of many candidates focusing only on exam-oriented learning while neglecting civilized driving practices. Starting from January 2013, the test is administered at the vehicle management office after completing the actual road test and driving test, following the same computer-based format as the theoretical exam.

What are the tips for hill start and stopping at a fixed point?

Hill start and stopping at a fixed point techniques are as follows: Lifting the clutch: When lifting the clutch, observe the RPM or the engine sound. When the RPM is appropriate or the engine emits a low sound, slow down the speed of lifting the clutch, then gently accelerate, align with the center of the road. Generally, there are arrows; align the center of the steering wheel with the arrow to drive. You can slightly lift the clutch to go uphill. Preventing rolling back: Before releasing the handbrake, it's best to observe the road conditions ahead. If it's an uphill or downhill, it's advisable to press the brake with your right foot, slowly release the clutch. When the car body starts to shake significantly, keep the clutch pedal steady with your left foot, slowly release the brake with your right foot. When the car starts moving, then completely release the brake.

How to Use the Cruise Control in the New BMW 5 Series?

BMW 5 Series cruise control usage method: 1. Press CRUISE to activate cruise control. 2. Briefly press the adjustment button towards RES+ or SET- once to increase or decrease the set cruise speed by 1km/h. 3. Briefly press the button towards SET- to set the current speed as the cruise speed. Precautions for using cruise control in the BMW 5 Series are as follows: 1. Basic cruise control does not automatically brake in emergencies; only vehicles equipped with adaptive cruise control can do so. However, full automation of electronic devices still requires gradual improvement, so it is recommended that drivers remain attentive to road conditions. 2. Braking serves as the termination signal for cruise control, but the previously set speed value remains stored in the system and can be directly resumed. 3. In complex road conditions or under adverse weather conditions, activating cruise control may pose risks. Please turn off cruise control and drive manually. 4. On downhill slopes, the vehicle may exceed the cruise speed. In such cases, use the foot brake as an assist and, if necessary, turn off cruise control.
