How Long Does Automotive Body Filler Generally Last?

With poor technique and improper maintenance, issues may arise within 1-2 years; with good technique and proper maintenance, it can last 7-8 years without problems. The functions of body filler are as follows: Functions of Body Filler: The role of automotive body filler is to be applied over the first or second primer after sanding in the automotive painting process, filling small defects, dents, scratches, or other processing marks to create a smooth surface for the next coat of paint. Its characteristics include high pigment and filler content, thick paste consistency for easy drying, hardening into a firm and fine texture after drying, and easy sanding. Content of Body Filler: So-called "small filler" refers to paint putty, used for relatively deep scratches. First, clean the dirt from the scratched area, wait until completely dry, then fill the damaged area with small filler. Next, lightly sand it smooth with fine sandpaper, and finally, use a touch-up pen for DIY paint repair. For larger or very deep damages, it is recommended to have it handled at a repair shop, where they typically use putty to level the surface before spraying paint, often requiring multiple coats.

What are the reasons for tire pressure loss?

The reason for tire pressure loss is that one or more of the vehicle's four tires are in a state of underinflation. It is necessary to use a tire pressure gauge to measure the pressure of all four tires and check whether the pressure values are within the specified range. If not, they should be replenished to the specified range. The standard tire pressure value can usually be found near the fuel tank cap or on the vehicle's B-pillar. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; causing heavy steering and easy deviation, which are factors detrimental to driving safety; increasing the movement of various parts of the tire, leading to abnormal heating due to excessive rolling; reducing the functionality of the cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, resulting in damage to the tire bead area and abnormal wear. Insufficient tire pressure: If no damage is visible, simply inflate to the normal tire pressure and reset the tire pressure system; if a puncture is found during inspection, promptly drive to a tire shop for repair and then reinflate; if the tire pressure warning appears again after inflation but there is no puncture, it may be due to air leakage caused by a deformed wheel rim, in which case it is recommended to inspect and replace the wheel rim.

What does the yellow exclamation mark on the Toyota Levin dashboard mean?

There are four possible scenarios when a yellow exclamation mark appears on the car dashboard: general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Faults: A triangle with an exclamation mark inside indicates a malfunction in the car's general performance, components, or functions. Common causes include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. 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 malfunction or transmission lubricant level below the normal range. 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 Fault: A yellow bulb with an exclamation mark 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. There is also a red exclamation mark inside a circle with brackets, which represents a brake system warning, mainly indicating brake system failure or low brake fluid level. The brake system should be inspected immediately to avoid accidents.

Do I need to press the unlock button every time I shift gears?

When shifting gears in an automatic transmission car, you must press the shift button for each gear change. Benefits of the button: The advantage of requiring a button to shift gears is to prevent accidental operation from affecting driving. For example, accidentally shifting from D to R while driving is very dangerous, so this shift button acts as a safety lock to prevent driver errors. Precautions for shifting gears: When shifting gears, the clutch and throttle must be coordinated properly. Press the clutch all the way down, then release the throttle pedal, and quickly shift to the corresponding gear. After shifting, release your hand immediately and avoid keeping it on the gear lever for a long time, as this can easily damage the gear lever.

How many days does it take to check the traffic violation record on October 1st?

It takes 7-10 days to check the traffic violation record on October 1st. Methods for determining traffic violations: Traffic violations are determined through electronic monitoring. Behaviors captured by electronic surveillance require manual review, which typically takes about 72 hours to upload the record. After that, it will be synchronized to the Traffic Management 12123 platform, and it takes 3-7 working days to query the violation record. Non-on-site violations: Non-on-site violations (violations captured by cameras) take about 15 days to be checked. The time varies in different regions. Therefore, if car owners are worried about potential violations, they can check online for relevant information about a week after they suspect a violation.

Do I need to keep pressing the brake when in N gear?

You don't need to keep pressing the brake when in N gear. N gear is neutral gear: In this gear, the transmission is also in a no-load state, but the vehicle can move. Unlike P gear, the transmission is not locked. Therefore, if you want to use the air conditioning while in N gear, you must engage the parking brake (handbrake) to prevent the vehicle from rolling. Definition of car braking: Braking, also known as stopping, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install a corresponding brake shoe, band, or disc on the machine base, which generates braking torque under external force.
