What to Do When a Vehicle Loses Control?

What is the content of the Subject 3 driving test? What is the passing score?

Subject 3 requires a score of 90 out of 100 to pass. Below is a detailed introduction to the point deductions for Subject 3: 1. Situations leading to failure: Not using the seatbelt as required. Obstructing or turning off the in-car audio and video monitoring equipment or not following the examiner's instructions. Incorrect use of lights, windshield wipers, or other common vehicle controls. Rolling backward more than 30 centimeters when starting. Both hands leaving the steering wheel simultaneously. Inability to choose the appropriate driving lane or control speed based on traffic conditions. 2. Test content: For large buses, tractors, city buses, medium-sized buses, large trucks, small cars, small automatic transmission cars, low-speed trucks, and small automatic transmission cars for the disabled, the test includes: preparation before starting, starting, driving in a straight line, shifting gears, changing lanes, parking by the roadside, driving straight through intersections, turning left at intersections, turning right at intersections, passing pedestrian crosswalks, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, making U-turns, and night driving.

Does the Mercedes-Benz E-Class AMG have a coupe version?

There is a coupe version, but only the E53 has a coupe variant. The Mercedes-Benz E-Class AMG comes in three models: the E43, E53, and E63s. These three models use different engines. Additional information: 1. The E43 is equipped with a low-power version of the 3.0-liter twin-turbocharged engine, the E53 uses a high-power version of the 3.0-liter twin-turbocharged engine, and the E63s is powered by a 4.0-liter twin-turbocharged engine. 2. The 3.0-liter twin-turbocharged engine in the E43 produces 401 horsepower and a maximum torque of 520 Nm. This engine reaches its maximum power at 6,100 rpm and its peak torque between 2,500 and 5,000 rpm. 3. This engine is paired with a 9-speed automatic transmission. The 3.0-liter twin-turbocharged engine in the E53 delivers 435 horsepower and a maximum torque of 520 Nm, with its maximum power achieved at 6,100 rpm and peak torque available from 1,800 to 5,800 rpm.

How to turn off the XPeng P7?

The XPeng P7 does not have a power-off button. Here is some relevant information about the XPeng P7: 1. Exterior Design: The XPeng P7 features the streamlined silhouette typical of a coupe, with low-drag design elements such as a fastback extending into a ducktail spoiler, semi-hidden wipers, and low-drag exterior mirrors. Additionally, the AGS active grille and an almost completely flat underbody contribute to reducing the drag coefficient, which plays a key role in enhancing the vehicle's range. The XPeng P7 Wing Edition incorporates avant-garde scissor doors at the front and comes with an exclusive Hyper Green exterior paint. The electric gull-wing doors are equipped with intelligent obstacle-avoidance radar. 2. Battery Features: The XPeng P7 is equipped with the latest generation of prismatic battery cells, with a rated energy of 80.87 kWh and an energy density of up to 170 Wh/kg. It also integrates the motor, electronic control unit, and reducer into a high-performance three-in-one electric drive system. Compared to traditional dispersed electric drive layouts, this three-in-one system offers higher efficiency, a more compact structure, lighter weight, more organized in-vehicle arrangement, and stronger reliability.

Is it a traffic violation to drive with a broken turn signal?

Driving with a damaged turn signal is considered a traffic violation. According to relevant traffic laws, operating a vehicle with non-compliant safety facilities or driving a motor vehicle that does not meet safety standards (violation code 1073) will result in a fine and 3 penalty points. All lights, as configured in the vehicle's technical documentation, must be complete and functional, including headlights, width indicators, fog lights, and for larger vehicles, corner roof lights and side lights. Below are common turn signal malfunctions: 1. When turning on the left or right turn signal or hazard lights, there is no normal clicking sound, and the turn signal does not light up: This is generally caused by two reasons—either the flasher relay is damaged, or the turn signal fuse has blown. The former can be replaced by oneself, while the latter requires a thorough inspection of the turn signal circuit for any short circuits before replacing the turn signal fuse. 2. When activating the left or right turn signal individually, the flashing frequency is inconsistent, with one side flashing faster than the other: This phenomenon is mainly due to a difference in the power of the turn signal bulbs on either side or poor contact somewhere in the turn signal circuit (most commonly at the connector). 3. The left or right turn signal works normally when activated individually, but when the hazard lights are turned on, one side does not light up: The main cause of this phenomenon is a faulty hazard light switch, which can be resolved by replacing the hazard light switch.

What to Do If the Reversing Radar Sound Is Too Low?

If the radar sound suddenly becomes too low, it may indicate an issue with the vehicle's related electronic equipment. Here are the relevant explanations: 1. Volume switch problem: If the reversing radar's volume adjustment switch is accidentally touched, it may cause the sound to become too low, which can be adjusted manually. 2. Power line failure: If the reversing radar sound is too low, check whether the host's power line is properly connected and whether there is current; then inspect whether the radar host line is loose. If neither of these is the issue, the problem may lie with the radar itself.

What Causes the Sudden Disappearance of Bass in BMW Harman Kardon Systems?

BMW Harman Kardon systems may experience sudden bass loss due to issues in three main components: the audio head unit, speakers, or amplifier, requiring inspection or adjustment at a repair shop. Below is relevant information about car subwoofers: 1. Principle: The internal amplifier circuit divides sound into several wavelength segments via a crossover. Mid-to-high frequency ranges (mid-high tones) are output to satellite speakers, while mid-to-low frequency ranges (mid-low tones) are directed to the subwoofer. Typically, subwoofers produce long-wave sounds between 20-200Hz, which are easily audible but difficult to localize due to their long wavelengths. These long waves exit through bass reflex ports, resonating with satellite speakers. The combined weak bass from the subwoofer and satellite speakers is then re-amplified by the satellites, creating an intense bass effect that perceptually seems to originate from the satellite speakers. 2. Function: Subwoofers enhance the bass frequency range, specifically amplifying long-wave audio components (below 100Hz, including infrasound which, though inaudible, still has an effect). Since standard speakers have limited size and cannot produce long-wavelength low frequencies, larger subwoofers are necessary to generate impactful low-frequency effects. Additionally, bass waves, being the longest, exhibit low efficiency in energy conversion, making their production highly energy-intensive—requiring greater input power to achieve equivalent output levels.
