What does an exclamation mark with a bracket illuminated on the car mean?

Red exclamation mark (specifically, an exclamation mark inside a circled bracket) represents a warning for the braking system, mainly indicating a braking system malfunction or low brake fluid level. Solution: Immediate inspection and repair of the braking system is required to avoid accidents. Apart from the red exclamation mark indicating a braking system fault, other exclamation marks on the car are yellow, representing general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates a fault in the car's general performance or components and functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor malfunction, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant level below the normal range. The transmission oil should be replaced promptly. Abnormal Tire Pressure: An exclamation mark with a horizontal line below a bracket. This represents the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, signaling a malfunction in the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.

Do You Need to Observe Traffic Lights When Making a Right Turn Without a Right-Turn Signal?

Generally, yes. Under normal driving conditions, drivers are required to wait for traffic lights when making a right turn. However, not all roads require waiting for traffic lights when turning right. Some roads have signs indicating that vehicles are allowed to turn right when it is safe to do so. There are two types of traffic lights: circular traffic lights and arrow-shaped traffic lights. When making a right turn, if the traffic light is circular and there are no auxiliary signs prohibiting a right turn on red, you do not need to wait for the light to turn green to make a right turn. If the traffic light is arrow-shaped, you cannot make a right turn when the right-turn arrow is red. You can only turn right when the right-turn arrow turns green. Otherwise, you may be penalized by law enforcement for running a red light. Laws and Regulations: 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 directions of traffic police. Article 26 specifies that traffic lights consist of red, green, and yellow lights. A red light indicates prohibition, a green light indicates permission, and a yellow light serves as a warning. Article 38 requires that vehicles and pedestrians shall proceed according to traffic signals. If there is a traffic police officer directing traffic on-site, they shall follow the officer's directions. On roads without traffic signals, they shall proceed under the principle of ensuring safety and smooth traffic flow. Article 62 states that pedestrians crossing intersections or roads shall use crosswalks or pedestrian facilities. When crossing at a signalized crosswalk, they shall follow the traffic light signals. When crossing at an intersection without traffic signals or crosswalks, or when crossing a road segment without pedestrian facilities, they shall proceed only after confirming safety. Article 89 stipulates that pedestrians, passengers, and non-motor vehicle drivers who violate road traffic safety laws and regulations regarding road usage shall be given a warning or fined between 5 and 50 yuan. Non-motor vehicle drivers who refuse to accept the fine may have their vehicles impounded. Motor vehicle drivers who violate traffic light signals will be penalized with 6 demerit points. Right-Turn Precautions: Observe oncoming straight-moving vehicles: When making a right turn, you must check both the right and left sides for oncoming traffic. Observe opposing left-turning vehicles: In addition to watching for straight-moving vehicles, you should also check for opposing left-turning vehicles. When turning right, yield to vehicles coming from the left, whether they are turning left or going straight. Watch for pedestrians: When making a right turn, be aware of crosswalks not only before the intersection but also at the corner. Always check for pedestrians on the crosswalk.

What does the ABS warning light in a car mean?

ABS light can illuminate in various states, with different causes and solutions for each state. The details are as follows: State 1: ABS warning light stays on (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting its ability to detect the vehicle's speed signal. This prevents the ABS control unit from determining the speed and calculating the wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the tone ring to restore normal function. Cause 2: Poor signal due to loose system wiring connections or faulty ABS relay contacts. Solution: Inspect wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple electrical devices are used, the battery voltage drops below 10.5V. As engine speed increases and voltage rises, the ABS light turns off. This may also occur due to insufficient power supply voltage to the ABS system, such as poor terminal contact or grounding issues. Solution: Check battery specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding connection of the ABS hydraulic valve body; loose wiring connector of the ABS hydraulic valve body; ABS control unit malfunction. Solution: Loosen and retighten the grounding screw of the hydraulic valve body, cleaning the contact surface if necessary; check for enlarged connector gaps; replace the ABS or ABS/ASR control unit. State 4: ABS warning light illuminates during high-speed driving. Cause: The ABS control unit detects a significant discrepancy between rear and front wheel speed signals during high-speed driving; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, typically listed on the fuel tank cap label. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal and push the brake switch linkage fully downward with a finger, then release the pedal to complete self-positioning; replace the brake light switch if necessary. If the ABS warning light is on, it is not recommended to continue driving. An illuminated ABS light indicates a malfunction in the anti-lock braking system. During emergency braking, locked wheels may cause the vehicle to skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's trajectory, posing significant safety risks.

Do U-turn Lanes Need to Obey Traffic Lights?

If the gap is marked with a dashed line, U-turns are not affected by traffic signals and do not require crossing the pedestrian crossing. In such cases, you can make a U-turn directly, provided it does not interfere with other normally moving vehicles and ensures your own safety. However, if the gap is marked with a solid line, then the U-turn must cross the pedestrian crossing and is subject to traffic signal regulations. When making a U-turn that requires crossing a pedestrian crossing, you must yield to pedestrians: If pedestrians are walking on the right side of the crosswalk and have not reached the centerline of the road, vehicles on the left side of the road should slow down and proceed cautiously, ensuring safety while allowing pedestrians to cross. If pedestrians are waiting outside the boundary of the motorized and non-motorized lanes and have not entered the roadway, vehicles should slow down and proceed cautiously, ensuring safety while allowing pedestrians to cross. If pedestrians have crossed the boundary between the motorized and non-motorized lanes, vehicles failing to stop and yield constitute a traffic violation and should be penalized. If pedestrians have entered the motorized lane (Lane A) via the crosswalk, vehicles in Lane B should slow down and proceed cautiously, ensuring safety while allowing pedestrians to cross. If vehicles in Lane A fail to stop and yield, it constitutes a traffic violation and should be penalized. If pedestrians are waiting at the centerline of the road without entering the motorized lane, vehicles failing to stop and yield constitute a traffic violation and should be penalized. If pedestrians have crossed the centerline of the road and entered the motorized lane, vehicles failing to stop and yield constitute a traffic violation and should be penalized. If the road is divided by a median with greenery and pedestrians are waiting in the median area, vehicles must slow down and proceed cautiously, ensuring safety while allowing pedestrians to cross. Scenarios where U-turns are permitted: Intersections with U-turn signs: If an intersection has a clear U-turn sign, U-turns are allowed. If there is a U-turn traffic signal, follow the signal's instructions. In the absence of a signal, make the U-turn based on the situation, ensuring it does not hinder other vehicles or pedestrians. Intersections without explicit U-turn or left-turn prohibitions: If there are no signs explicitly prohibiting U-turns, they are allowed. "No explicit prohibition" means the intersection lacks signs like "No U-turn," "No Left Turn," or solid centerlines, making U-turns permissible. Yellow grid lines also permit U-turns: Yellow grid lines are no-stopping zones typically marked at intersections prone to congestion due to temporary stops, important facility entrances, or other critical locations. Stopping on these grid lines (including waiting for traffic lights) is a violation. While stopping is prohibited, U-turns are allowed in these areas as long as there is no median barrier, effectively treating them as "U-turn permitted" zones. Intersections with U-turn traffic signals: This is straightforward—if a U-turn signal is present, follow it; U-turns are only allowed on green. When "No Left Turn" and "U-turn Permitted" signs coexist: U-turns are allowed, but left turns are prohibited. Note that "No U-turn" is not the same as "No Left Turn." Important considerations for U-turns at intersections: Check road markings: If the line is solid, U-turns are prohibited under any circumstances. Continue driving to find a suitable location. If a "No Left Turn" sign is present, even without a "No U-turn" sign, U-turns are not allowed at that intersection, as U-turns inherently involve a left-turn motion. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, U-turns are not permitted at that intersection. Always yield to oncoming traffic when making a U-turn. Proceed only if it does not disrupt the normal flow of straight-moving vehicles; otherwise, you bear full responsibility for any accidents. Near intersection stop lines, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow—some may have straight arrows. Even without explicit "No U-turn" signs, U-turns are prohibited in such lanes.

How to Change the Transmission Fluid for an Old Sylphy 4AT?

Lift the car, unscrew the transmission oil pan drain plug at the bottom of the car, and the transmission fluid will drain naturally. Once no more fluid flows out, tighten the plug. Use a fluid exchange machine, which can inject new fluid into the transmission while extracting the mixed old and new fluid until the fluid inside the transmission becomes clear.
