Q represents 160 km/h, R represents 170 km/h, S represents 180 km/h; 2. T represents 190 km/h, H represents 210 km/h, V represents 240 km/h; 3.

What does RCTA on a car refer to?

RCTA on a car refers to the Rear Cross Traffic Alert system. The RCTA system is designed to alert the driver to vehicles approaching from the sides or rear when reversing. When backing out of a parking space, it identifies and warns of vehicles coming from the left or right, assisting in the reversing process. More details about RCTA are as follows: 1. The RCTA system is designed to help drivers check the areas on both sides of the rear of the vehicle, alerting the driver if there are vehicles approaching from behind when the vehicle is in reverse. 2. When the vehicle is reversing, the RCTA system uses BSM radar to detect other vehicles in the blind spot behind the vehicle. 3. If the RCTA system determines that an approaching vehicle from behind may collide with the vehicle, it will sound an alarm, and the BSM indicator icons on both side mirrors will also flash to alert the driver, thereby reducing the likelihood of a collision. 4. When the vehicle is reversing and gets too close to a hazardous object or obstacle, or if a pedestrian, animal, or moving vehicle suddenly approaches the rear of the vehicle during reversing, and the driver fails to notice or brake in time, the system will intelligently and automatically apply the brakes to prevent accidents involving collisions with people or other vehicles.

What Insurance Does a Sedan Need?

Sedans generally need to purchase three types of insurance: compulsory traffic insurance, vehicle damage insurance, and third-party liability insurance. Insurance should be selected based on your actual situation. Compulsory Traffic Insurance: As one of the legally required insurances, compulsory traffic insurance mandates that the insurance company must pay a certain amount to the affected party if any loss is caused to a third party, regardless of fault or whether compensation is required. However, in cases of at-fault traffic accidents, the cost may increase by 10%-30% based on annual occurrences or frequency. Vehicle Damage Insurance: Vehicle damage insurance is also typically necessary. For everyday issues like scratches, repair costs can be claimed from the insurance company. Especially after an accident, if the responsible party cannot be identified, the insurance company will cover 70% of the costs. However, compensation under vehicle damage insurance is based on the vehicle's usage time and depreciation, with an annual depreciation rate usually set at 7.2%. Third-Party Liability Insurance: Fully known as third-party liability insurance, it is a type of liability insurance. It covers the financial compensation that the insured must legally or customarily bear due to their own fault or negligence causing personal injury or property damage to a third party, with the insurer assuming this responsibility.

What are the causes of steering lock failure?

Steering lock failure can be attributed to the following reasons: 1. Generally, it is caused by internal dirtiness, clogged filter screens, or low oil level in the oil cup. 2. A large amount of air in the power steering system may also lead to electronic steering lock failure. 3. Foreign objects in the steering system causing the steering pump flow control valve to stick, insufficient tire pressure, interference in the steering column, loose connections, loose or slipping pump belts, or loose pump installation positions can also result in electronic steering lock failure. 4. Loose bolts at oil pipe connections leading to steering fluid leakage, excessive wear of the steering gear piston cylinder, poor sealing of oil seals, or sticking and damage of the control valve are also causes of the failure. When steering lock failure occurs, it is necessary to inspect the steering gear, steering pump control valve, oil cup filter screen, and steering oil, as well as clean the entire power steering system.
