Never ignore a linear crack on the tire sidewall! Last week, my neighbor's car had a sudden blowout on the highway because of this, almost causing a rear-end collision. What looks like a thin crack is actually a sign of internal cord layer fracture, which can tear completely at any moment. Tire repair shops will outright refuse to patch it—the sidewall is too thin and bears bending pressure, making patches or mushroom plugs ineffective. The safest move is to head straight to a tire shop for a new replacement. When changing the tire, ask the mechanic to carefully inspect the other side for similar aging cracks. Also, avoid scraping curbs when parking, as sidewall scratches are the most likely to become hidden hazards.

What should you do if a car hits a person?

Call the police, report to the insurance company, and rescue the injured. If you flee the scene after a traffic accident involving hitting a person, you will be held accountable based on the consequences. If the other party has minor injuries, they will usually ask you to accompany them to the hospital and pay the bills. At this point, you should generally say you didn’t bring any money because the responsibility hasn’t been determined yet. In many cases, you may not be fully at fault. If you pay upfront and it turns out you’re not responsible, it will be difficult to get your money back. No matter what, don’t pay upfront. Just go to the traffic police station the next day and handle it properly—there’s nothing to worry about. Violating transportation management regulations, thereby causing a major accident that results in serious injury, death, or significant loss of public or private property, is punishable by up to three years in prison or criminal detention. Generally, when the police (110) arrive at the scene, the process is straightforward. If an ambulance (120) is needed, they will handle their duties. After you report the incident to your insurance company, they may not come to the scene unless it’s a major accident, as they can obtain scene photos from the traffic police station. For minor incidents, the insurance adjuster can issue an on-site damage assessment report. For larger incidents, the assessment is usually done later at a repair shop after disassembly. For most cases, the damage assessment report can be issued after disassembly and inspection. Fleeing the scene of a traffic accident or exhibiting other particularly egregious behavior is punishable by three to seven years in prison. If fleeing the scene results in death, the punishment is seven years or more in prison. If someone is injured, it’s generally important to preserve the original scene. For serious injuries, prioritize assisting in rescuing the injured—though it’s best to leave it to professionals like 120 responders. For example, moving someone with a spinal fracture improperly could worsen their injuries. For major cases, repairs are done gradually, with photos taken at each stage. Before the repairs are fully completed, the vehicle should be road-tested. If issues are found, more photos are taken. Finally, after everything is resolved, the final damage assessment report is issued. This ensures the repair costs don’t exceed the assessed amount. Otherwise, if the report is issued too early, it’s hard to make changes if problems arise later.

What is the fuel consumption of the Toyota Reiz 2.5v?

Toyota Reiz 2.5v has a total of 5 models on sale, including the 2013 2.5V Jingrui Edition, 2013 2.5V Shangrui Edition, 2013 2.5V Shangrui Navigation Edition, etc. These 5 models equipped with a 193 horsepower engine have an NEDC fuel consumption of 9L per 100 kilometers. The fuel tank capacity of different Toyota Reiz 2.5v models varies. The distance that can be covered with a full tank of fuel is as follows: Models equipped with a 193 horsepower engine have a fuel tank capacity of 70L. The distance that can be covered with a full tank is 70/9*100=778KM. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase a car's fuel consumption are as follows: Driving habits: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not releasing the throttle in advance when approaching a red light can increase fuel consumption. The car itself: Cars with larger displacement generally consume more fuel than those with smaller displacement because larger displacement usually means greater power, requiring more gasoline to burn and perform work. Heavier cars also have higher fuel consumption because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperature: When the engine block temperature is low during cold starts, the injected gasoline is less likely to atomize, requiring more gasoline to be injected for combustion, thus increasing fuel consumption. Additionally, at low temperatures, the engine's computer will control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

What to Do When the ABS Light in the Car Comes On?

There are various states when the ABS light comes on, with different causes and solutions for each state. The details are as follows: State 1: The ABS warning light stays on constantly (most common). Cause 1: The ABS speed sensor's sensing part is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt off the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections between system lines or poor contact of the ABS relay, leading to system failure. Solution: Check the line connections and reconnect any loose parts. State 2: The ABS warning light intermittently comes on but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases, the voltage rises, causing the ABS indicator light to turn off. The ABS system's power supply voltage is too low, possibly due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity, inspect the charging system, and examine the power supply (e.g., voltage relay or poor power contact). State 3: The ABS warning light stays on after the engine starts and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact of the ABS hydraulic valve body; poor contact of the ABS hydraulic valve body's wiring connector; ABS computer malfunction. Solution: Loosen the grounding screw of the hydraulic valve body, then retighten it, cleaning the contact surface if necessary. Check if the connector gap has widened; replace the ABS or ABS/ASR computer if needed. State 4: The ABS warning light comes on during high-speed driving. Cause: At high speeds, the ABS computer detects a significant difference between the rear and front wheel speed signals. Incorrect tire or wheel rim specifications may also be the cause. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: The ABS warning light intermittently comes on. Cause: Improper adjustment of the brake light switch; poor internal contact of the brake light. Solution: With the engine running, press the brake pedal and use a finger to push the brake switch linkage down fully, then release the brake pedal to complete the self-setting position. Replace the brake light switch if necessary. If the ABS warning light comes on, it is advisable not to continue driving. An illuminated ABS light indicates a fault in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's trajectory, posing significant safety risks.

Under Which Light Can You Turn Right at a Red Light?

You can turn right at a red light under the following circumstances: If there is an arrow signal light at the intersection, right turns are only permitted when the right-turn arrow is green; otherwise, right turns are prohibited. If there is a sign prohibiting right turns at a red light at the intersection, right turns are only allowed when the light is green. If there are no other signs at the intersection, vehicles can turn right at a red light as long as it does not interfere with the normal movement of other vehicles and pedestrians. Circular traffic lights, arrow-shaped right-turn indicators, or circular red lights with an additional sign. Generally, drivers need to observe traffic lights when making a right turn, but not all roads require waiting for a green light to turn right. When there is a sign at the end of the road, some signs allow vehicles to turn right under safe conditions. Circular traffic lights: If the circular traffic light turns red at an intersection, vehicles in the right-turn lane can proceed to turn right. However, you must ensure not to interfere with other vehicles, as well as pedestrians and vehicles on the rear and right side of the road. Arrow-shaped right-turn indicators: If you encounter an arrow-shaped right-turn sign at an intersection, you cannot turn right when the red arrow is lit. If you turn right, it will be considered running a red light. Circular red lights with an additional sign: At some complex intersections, you may encounter a sign above the traffic light indicating whether right turns are allowed at a red light. If the sign says "Right Turn on Red," you can turn right. If it says "No Right Turn on Red," you must wait for the green light. Laws and regulations: According to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," motor vehicle and non-motor vehicle traffic signals indicate: When the green light is on, vehicles are allowed to proceed, but turning vehicles must not hinder the passage of straight-moving vehicles and pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motor vehicle or pedestrian crosswalk signals, non-motor vehicles and pedestrians should follow the instructions of motor vehicle traffic signals. When the red light is on, right-turning vehicles may proceed if they do not hinder the passage of other vehicles and pedestrians. According to the "Road Traffic Safety Law," the regulations on traffic lights are as follows: Article 25, Paragraph 2 states that traffic signals include traffic lights, traffic signs, traffic markings, and the direction of traffic police. Article 26 states that traffic lights consist of red, green, and yellow lights. Red means stop, green means go, and yellow means caution. Article 38 states that vehicles and pedestrians should follow traffic signals; when directed by traffic police on-site, follow their instructions; on roads without traffic signals, proceed under the principle of ensuring safety and smooth traffic. Article 62 states that pedestrians should use crosswalks or pedestrian facilities when crossing intersections or roads; at crosswalks with traffic lights, follow the traffic light signals; at intersections without traffic lights or crosswalks, or when crossing roads without pedestrian facilities, proceed after confirming safety. Article 89 states that pedestrians, passengers, and non-motor vehicle drivers who violate road traffic safety laws and regulations regarding road passage will be given a warning or fined between 5 and 50 yuan; non-motor vehicle drivers who refuse to pay the fine may have their vehicles impounded. Driving a motor vehicle in violation of traffic light signals will result in a 6-point penalty. Right-turn precautions: Observe straight-moving vehicles on the left: When turning right, you must check both the right and left sides for oncoming vehicles. Observe left-turning vehicles from the opposite direction: In addition to straight-moving vehicles, also check for left-turning vehicles from the opposite direction. When turning right, yield to vehicles on the left, whether they are turning left or going straight. Observe pedestrians: When turning right, besides the crosswalk before the intersection, there may also be a crosswalk at the corner. Always check for pedestrians on the crosswalk when turning right.

Do I need to change tires when modifying wheel size?

Modifying wheel size requires changing tires. Tire replacement timing: It is recommended to replace tires every four years, even if the mileage is relatively low during those four years. Tires are rubber products, and rubber products will age over time with prolonged use. Tire selection: When purchasing tires, be sure to check the specifications and model clearly, as well as the production date, speed rating, and load index. Generally, the sidewalls of tires for family cars or SUVs will have markings like 91V. After reinstalling tires, it's essential to perform wheel balancing to prevent abnormal vibrations during high-speed driving.
