What does the red exclamation mark warning signal in an Audi car indicate?

The red color indicates a very serious problem in the corresponding system. When this occurs, do not continue driving. Pull over safely and seek professional assistance immediately to prevent unpredictable risks to both the vehicle and personal safety. An exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. There are many dashboard warning lights with exclamation marks, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and windshield wiper fault indicator. Below is a detailed explanation of exclamation mark warning lights: General Fault: A triangle with an exclamation mark inside indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor faults, fuel cutoff system intervention or malfunction, external light faults, engine oil pressure sensor faults, 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 is the automatic transmission fault warning light, indicating a transmission fault or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circle with parentheses indicates a brake system warning, typically due to a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Abnormal: An exclamation mark with a horizontal line below parentheses is the tire pressure monitoring warning light. It illuminates when the 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 is the lighting fault indicator, signaling a fault in the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or check the commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. In addition, during daily vehicle use, the fault lights displayed on the dashboard are divided into two colors—yellow and red—for different levels of severity: Yellow indicates a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the nearest repair point to eliminate potential safety hazards. Note: When the car is started, all warning lights will illuminate as the system performs an automatic check. They should turn off after the check is complete. If a light does not illuminate when the ignition is turned on, remains lit, or lights up while driving, it indicates a fault in the corresponding system. In such cases, seek professional help immediately for inspection and to eliminate safety hazards.

What is the tire model and size for the Nissan Sunny?

The tire size model for the Nissan Sunny is 185/70R14. In the 185/70R14 specification, the first number 185 represents the tire width of 185MM. The 70 indicates the aspect ratio of the tire section is 70%, meaning the section height is 70% of the width. The 14 denotes the rim diameter of 14 inches. The letter R in the middle stands for radial tire. The Nissan Sunny is equipped with aluminum alloy wheels and Yokohama BlueEarth-A34 series tires, with a non-full-size spare tire. If you wish to replace the tires yourself, you can follow these steps: Retrieve the spare tire and jack, place the jack under the vehicle frame near the tire to be replaced, ensuring the jack contacts the metal part of the frame; Raise the jack until it supports the car, making sure the jack is positioned under the vehicle and at a right angle to the ground; Remove the hubcap, loosen the nuts counterclockwise without fully removing them, just enough to eliminate resistance. Keeping the tire on the ground when first loosening the nuts ensures the nuts turn rather than the tire; Turn the nuts counterclockwise until they are loose, repeat this step for all lug nuts, then completely remove the nuts; Place the new tire on the wheel hub, carefully aligning the tire rim with the wheel bolts, install the lug nuts, and hand-tighten them until all nuts are snug. At this point, the tire replacement is complete. In addition to the model, tires also display the following common data: Tire cord material: Indicated by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, ZG for steel radial cord tires. Speed rating: Indicates the maximum speed the tire can carry a specified load under specified conditions. Letters A to Z represent certified speed ratings from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: Shows the rim size compatible with the tire for practical use, such as standard rim 5.00F.

What Causes the ABS Yellow Light to Illuminate in a Car?

ABS light illumination can occur in various states, with different causes and solutions for each state. The details are as follows: State 1: ABS warning light stays on constantly (most common). Cause 1: The ABS wheel speed sensor's sensing area 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 wheel slip rate, thus failing to issue appropriate commands to adjust braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections between system wires or poor contact of the ABS relay, leading to system failure. Solution: Check wire connections and reconnect any loose parts. State 2: ABS warning light illuminates intermittently and 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 to turn off. This may also occur if the ABS system power supply voltage is too low due to poor terminal contact or grounding issues. Solution: Check the battery's 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 contact of the ABS hydraulic valve body; poor contact of the ABS hydraulic valve body wire connector; ABS computer malfunction. Solution: Loosen and retighten the grounding screw of the hydraulic valve body, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. State 4: ABS warning light illuminates during high-speed driving. Cause: At high speeds, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light illuminates intermittently. 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 is on, it is advisable not to continue driving. An illuminated ABS light indicates a malfunction 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.

What to Do If Driving License Training Hours Are Insufficient?

If the required training hours have not been recorded, you should promptly go to the driving school to make up the missing hours for the corresponding subject. Only after review and approval can you schedule the exam. Some driving schools do not strictly enforce the recording of training hours due to the lack of linkage between training attendance and exam scheduling, as well as network failures, which has left many unable to schedule their exams.

What to do if the three-year validity period for obtaining a driver's license has expired without passing?

If you have already passed Subject 1 but haven't completed Subject 2 or Subject 3, your records will be cleared regardless, and your file will be canceled. If you haven't even taken Subject 1, then the validity period hasn't been exceeded. In this case, you should check whether the contract signed with the driving school specifies a time limit.
