When a yellow exclamation mark appears on the car dashboard, there are four possible scenarios: general malfunction, automatic transmission failure, abnormal tire pressure, or lighting system issues. Below is a detailed analysis of each situation: General Malfunction: A triangle with an exclamation mark inside indicates a general performance or component malfunction. Common causes include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor issues. It is advisable to visit a 4S shop for diagnosis and repair to identify the source of the problem. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission warning light, indicating a transmission malfunction or low transmission fluid level. The transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark inside a horizontal line under a bracket represents the tire pressure monitoring warning light. This light illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Issues: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the vehicle'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. Additionally, a red exclamation mark inside a circle with brackets indicates a braking system warning, typically due to braking system failure or low brake fluid level. Immediate inspection and repair of the braking system are necessary to prevent accidents.

How to Unscrew Rusty License Plate Bolts?

Methods to unscrew rusty license plate bolts: 1. Use a rust remover to clean the threads, then try to unscrew it; 2. Prepare a flathead screwdriver and a Phillips screwdriver, each equipped with an angle grinder. Connect the angle grinder to the power source, plug it in, then hold the grinder's handle with both hands. Use your right hand to turn on the angle grinder's switch, and cut a straight slot on the license plate bolt cap with the angle grinder to remove it. For car owners without an angle grinder, you can try using needle-nose pliers or duckbill pliers to firmly grip the bolt ring. Once the bolt ring is deformed, release the pliers, then insert a flathead screwdriver into the deformed area and use inertia to remove the bolt cap. After removing the license plate bolts, be sure to clean up the bolts promptly and avoid littering, as they could potentially puncture the vehicle's tires.

What Causes the Clicking Sound Outside the Car When Shifting an Automatic Transmission?

Automatic transmission shifting with abnormal sounds can be attributed to the following reasons: 1. Large valve clearance when the engine is cold: Poor lubrication during the transition from cold to hot engine state may cause noise when shifting, lasting about 3 minutes, which is a normal phenomenon. 2. Problems caused by parking on a slope: If the P (Park) gear is engaged first before applying the handbrake when parking on a slope, an external force due to inertia will cause the vehicle's weight to be entirely borne by the P gear, resulting in noise when shifting; if the handbrake is applied first, the handbrake bears the force, and no noise will occur. 3. Transmission issues: Wear and tear on the transmission, loose drive shaft, differential wear, wear on the transmission's output shaft, gear wear, or malfunctioning shift mechanism require immediate attention at a 4S shop or professional auto repair shop for technician repair.

What do the three modes of Outlander 4WD mean?

The following is a detailed introduction to the three modes of Outlander 4WD: 1. The eco mode is used under normal driving conditions, which is relatively fuel-efficient and allows the vehicle to turn more smoothly. It is generally used when driving in urban areas, offering the best fuel economy. 2. The auto mode is typically used in rainy or snowy weather, where a noticeable increase in power can be felt. The downside is that the engine noise increases, and fuel consumption rises. It is generally used on rainy gravel roads, muddy roads, mountain roads, and highways. 3. The lock mode is the four-wheel-drive mode, used on rugged mountain roads, usually for escaping difficult situations or climbing steep slopes. The 4WD lock mode should not be used for extended periods, as it will significantly increase fuel consumption, engine noise, and temperature, causing considerable damage to the engine, transmission, and other drivetrain components, thereby shortening the vehicle's lifespan.

Can I wear a skirt for the Subject 2 driving test?

Generally, it is not recommended to wear a long skirt while practicing driving, as it may easily get tangled with the clutch or brake pedals, posing safety hazards. Below are precautions for the Subject 2 test: 1. Reverse parking into a garage: (1) Ensure accurate alignment with reference points and lines, observing the distance between the car body and lines via rearview mirrors to avoid crossing boundaries. (2) Do not stop until the vehicle is fully inside the garage; control the clutch properly to prevent midway stops or incomplete parking. After entering the area, park at the designated spot, then reverse into the garage; exit towards another direction and repeat the process; finally exit towards the test area to complete the exam. 2. Parallel parking: (1) Maintain proper side distance when aligning with the garage to avoid crossing lines, and watch for not hitting garage corners when exiting. (2) Remember to activate turn signals when exiting. After entering the area, align parallel to the garage, drive to its front-left side, reverse into the garage from the right rear, then exit to finish the test.
