How to Determine the Position of the Right Front of the Car While Driving?

What does Auto Hold mean?

Auto Hold refers to an automatic braking function. After activating this feature, for example, when stopping at a traffic light, it eliminates the need to pull the handbrake, avoiding the operation of using the handbrake or electronic parking brake. For automatic transmission models, it also reduces the frequent switching between D to N or D to P. During driving, when a temporary stop is required, the system will automatically brake the wheels after the vehicle comes to a complete stop to prevent rolling, eliminating the need to remember to pull the handbrake. When starting the vehicle, the system will automatically apply the brakes to prevent backward sliding. Once the forward traction reaches a level sufficient to move uphill, the system will automatically release the brakes for forward movement. When parking and locking the vehicle, the system will automatically brake the wheels at that moment.

What are the differences between an automatic transmission driver's license and a manual transmission driver's license?

An automatic transmission driver's license refers to a C2 license, while a manual transmission driver's license refers to a C1 license. The following are the specific differences between a C1 license and a C2 license: 1. Permitted vehicle types: A C1 license allows the holder to drive small and micro passenger vehicles, as well as light and micro cargo vehicles, and light, small, and micro special-purpose vehicles. A C2 license, on the other hand, permits driving small and micro automatic transmission passenger vehicles and light and micro automatic transmission cargo vehicles. 2. Medical examination requirements: For a C1 license, holders aged 70 and above must undergo an annual medical examination, whereas for a C2 license, holders aged 60 and above must have an annual medical check-up. 3. Training aspects: Generally, the training fees for a C2 license are slightly higher than those for a C1 license.

How many points are deducted for changing lanes by crossing the solid line?

Changing lanes by crossing the solid line results in a deduction of 3 points. The lane markings on the road are divided into solid lines and intermittent dashed lines. According to regulations, lane changes are generally allowed at dashed lines without affecting the normal driving of other vehicles, but lane changes are prohibited at solid lines. Traffic violations such as crossing the yellow line for left turns or merging at solid lines often occur during peak traffic hours or at signalized intersections without police command where branches and main roads intersect. The hazards of changing lanes by crossing the solid line include: 1. Vehicles at intersecting intersections cannot drive normally, easily causing traffic congestion; 2. Vehicles crossing the yellow line for left turns enter the intersection without slowing down, making it difficult to take emergency braking measures in case of danger, which can easily lead to traffic accidents.

What are the reasons for unstable car idling with fluctuating RPM and stalling?

Specific reasons for unstable car idling with fluctuating RPM and stalling are as follows: 1. Intake manifold air leak: When unauthorized air, gasoline vapor, or combustion exhaust enters the intake manifold, it causes the air-fuel mixture to become too rich or too lean, leading to unstable car idling. 2. Excessive carbon buildup in the throttle body: Excessive carbon deposits in the throttle body and surrounding intake passages alter the cross-sectional area of the air passage, preventing the control unit from precisely regulating the idle air intake. This also results in an overly rich or lean mixture, causing unstable car idling. 3. Malfunction of intake system actuators: The engine's intake system has numerous actuators, such as the throttle motor, idle stepper motor, duty cycle solenoid valve, air flow meter, and intake pressure sensor. Faults or damage to these components can lead to unstable car idling. 4. Fuel system malfunction: Issues like clogged fuel injectors, blocked fuel filters, obstructed fuel pump screens, faulty fuel pressure regulators, or blocked return fuel lines can all result in incorrect fuel injection, causing the mixture to be too rich or too lean and leading to unstable car idling. 5. Ignition system malfunction: Faults such as a malfunctioning ignition module, incorrect spark plug gap, eroded or damaged spark plug electrodes, or excessive resistance in high-tension wires can reduce ignition spark energy or cause misfires, resulting in unstable car idling with fluctuating RPM.

What Causes the Dashboard Lights of a Mercedes-Benz to Dim?

The reason why the dashboard of a Mercedes-Benz C200L dims is due to the activation of the automatic headlights, which are highly sensitive to light. Definition of Car Dashboard: The car dashboard is a device that reflects the working conditions of various vehicle systems. Common indicators include the fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, and warning lights. Introduction to the Tachometer: The tachometer is usually located within the instrument panel, symmetrically placed alongside the speedometer. It operates based on magnetic principles, receiving pulse signals generated when the primary current in the ignition coil is interrupted. These signals are then converted into a readable speed value. The faster the engine speed, the more pulses the ignition coil generates, resulting in a higher displayed speed value on the tachometer.
