Most modern cars are equipped with only one reverse light on the right side, while only a few vehicles have two brake lights. The specific reasons are as follows: 1. Improving visibility on the passenger side: When reversing, the driver's side visibility is hardly affected, as the brake lights and width markers provide sufficient illumination. However, visibility on the passenger side is poorer, requiring the white light from the reverse light to enhance it. 2. Preventing confusion with brake lights: Having a single reverse light makes it more noticeable to drivers behind and helps avoid confusion with brake lights. In many developed countries, having only one reverse light is mandated by law.

How many degrees can the steering wheel not exceed when driving straight?

When driving straight, the steering wheel should not exceed 5 degrees. Correct operation of the steering wheel: Place both hands with appropriate force at the nine o'clock and three o'clock positions on the steering wheel. The four fingers should naturally grip firmly, and the thumbs should naturally extend along the edge of the steering wheel. Steering wheel techniques: When driving straight on a flat road, use the "correction method" to control the steering wheel. The correction method involves making minor adjustments only when the direction deviates from the driving centerline. Each adjustment should be limited to within 30 degrees to ensure smooth vehicle movement. For gentle turns, steer early and slowly, and return early and slowly. For sharp turns, steer late and quickly, and return early and quickly. Develop predictive ability by preparing your hands for the turn before it begins.

What is the Chinese name for the Volkswagen Arteon?

Volkswagen Arteon is actually the successor to the Volkswagen CC, and FAW-Volkswagen has yet to announce a Chinese name for the Arteon. Over the past year, FAW-Volkswagen has likely been debating whether to assign a Chinese name to the Arteon. Now, the decision has been made, and FAW has abandoned this idea. Here are the detailed specifications of the Volkswagen Arteon: 1. Exterior Design: The Volkswagen Arteon retains design elements from the Sport Coupe GTE concept car. The front grille is adorned with extensive chrome accents and seamlessly connects with the headlight assembly. The L-shaped LED daytime running lights add a striking touch. The new model continues to feature a four-door fastback design, with sharper angles compared to the current model. The side profile showcases a prominent waistline that runs from the front to the rear, complemented by a subtly raised ducktail spoiler at the back, enhancing its sporty coupe positioning. 2. Powertrain Options: The Volkswagen Arteon offers three gasoline and three diesel engine options. The gasoline lineup includes a 1.5 TSI Evo engine with a maximum power output of 110 kW (150 PS), as well as two differently tuned 2.0 TSI engines producing 140 kW (190 PS) and 206 kW (280 PS), respectively. Transmission options include a 6-speed manual or a 7-speed dual-clutch gearbox, with front-wheel drive or all-wheel drive configurations available.

Can You Buy a Pass for Subject One?

No, you cannot buy a pass. Subject One refers to the driver's theory test, which is a mandatory licensing exam conducted by the vehicle management office for all driver's license applicants. The test covers the most fundamental knowledge, including driving theory basics, road safety laws and regulations, traffic signals, traffic rules, and local regulations. The scheduling of the driver's theory test is arranged by the local vehicle management offices. Subject One is part of the teaching and examination outline for motor vehicle driver training. The examination portion of this outline is divided into three subjects, organized by the traffic management departments of public security authorities. The exams proceed in the order of Subject One, Subject Two, and Subject Three. Only after passing the previous subject can you proceed to the next one; if you fail a subject, you must retake it. Precautions for Subject One of the driving test: Follow the staff's instructions and collect your driving training file in order in the waiting area. Carry and present your ID card for inspection by the supervising officer. Turn off your mobile phone when entering the examination area. No loud talking is allowed in the examination area. Do not bring regulation textbooks into the examination area (or keep them in your bag). After the test, keep your ID card safe and submit the file to the "Document Submission Window" at the front of the examination area. Candidates who pass the test should sign under the guidance of the staff at the exit before leaving the examination area. Candidates who fail the test can leave the examination area and wait for their driving school to notify them of the retake schedule.

How to Turn Off the Auto Start-Stop Function in Mercedes-Benz?

Mercedes-Benz's start-stop function is enabled by default when the vehicle starts. Pressing the start-stop function button once can deactivate the auto start-stop feature. To use this function again, simply press the button to reactivate it. The icon for the auto start-stop system switch is an "A" enclosed within a circle. The following situations require turning off the auto start-stop function: 1. When driving on steep slopes, it is advisable to avoid using auto start-stop. Although the start-stop duration is brief, the engine's start-stop on a slope may lead to insufficient brake assistance. 2. During extremely hot weather in southern regions when the air conditioning is running at full capacity, it is best to deactivate the auto start-stop function. This is because the air conditioning requires significant power consumption, and the vehicle's electrical system may not provide enough power to operate the air conditioning when the engine is off, potentially causing discomfort to passengers.

Why Are Both Left and Right Turn Signals Lighting Up Simultaneously?

When both the left and right turn signals of a car light up at the same time, it could be due to the hazard lights being turned on, the car's anti-theft system activating, or a computer malfunction. Hazard lights switch turned on: If the hazard lights switch is activated or stuck in the on position, it will cause both turn signals to light up simultaneously. In emergency situations, when the hazard warning signal switch is engaged, all turn signals flash together to indicate that the vehicle is in an emergency and requests other vehicles to yield. Car anti-theft system activation: If an unauthorized key is used to enter the car or any other form of illegal entry occurs, it may cause both turn signals to light up simultaneously. Circuit malfunction: Water ingress into the vehicle's computer or the presence of condensation, among other issues.
