The appearance of a small wrench light on the car display is a maintenance reminder indicator. Below are the items for car maintenance: 1. Replacement: Change engine oil and oil filter. 2. Inspection and replenishment: Check and top up the auxiliary tank water level, check and top up the windshield washer fluid, check and top up the tire pressure for all four wheels. 3. Cleaning: Perform an engine cleaning. Below is extended information on car maintenance intervals and key contents: 1. 5,000 km: After driving 5,000 km, replace the engine oil and oil filter. 2. 10,000 km: After driving 10,000 km, replace the engine oil, oil filter, air filter, and fuel filter. 3. 15,000 km: After driving 15,000 km, replace the engine oil, oil filter, and cabin air filter. 4. 20,000 km: After driving 20,000 km, replace the engine oil, oil filter, air filter, and fuel filter. 5. 25,000 km: After driving 25,000 km, replace the engine oil and oil filter.

When I used to drive my old car, I often saw the little wrench light come on, which is the car reminding you it's time for maintenance. It could be that the mileage has reached the preset point, or it's been too long since the last service. The most common reason is needing an oil change—once the oil gets old, the engine's lubrication effectiveness decreases, leading to increased wear and louder noise. I ignored it once and delayed the repair for two weeks, only for the technician to say the poor oil quality was affecting the engine's lifespan, costing me more in repairs. Now, whenever I see this icon, I first check the maintenance schedule in the manual, arrange for service at a 4S shop or professional repair shop, and then simply reset the reminder using the steering wheel buttons. Developing good maintenance habits can extend your car's lifespan and reduce problems on the road.

How Long Is the New Car Warranty Period?

New car warranty period is 3 years or 60,000 kilometers. The car warranty period refers to the time frame during which the car manufacturer promises to provide free repairs and maintenance for faults caused by quality issues when selling the product to consumers. During the warranty period, not all vehicle repair costs are waived; it depends on the free items specified by the manufacturer during the warranty period. Usually, there are relevant written descriptions in the owner's manual and the after-sales departments of various car 4S stores, so car owners should carefully read the manual to avoid spending unnecessary money during the warranty period. The so-called car warranty period does not actually mean that the owner can repair or replace parts at will. The warranty contract actually specifies different scopes such as important component warranty period, large parts warranty period, comprehensive warranty, and full warranty.

Is It Necessary to Replace a Rusty Transmission?

It is necessary to replace a rusty transmission because rust can cause gear shifting issues, such as difficulty engaging gears or gear slippage, which compromises driving safety. Below are details about transmissions: 1. Function: A transmission is a gearbox that changes the transmission ratio and direction of motion. Located between the clutch and the central drive, its main purposes are: changing the vehicle's driving force and speed (gear shifting) without altering the engine's speed and torque; enabling the vehicle to move backward (reverse); and allowing the engine to idle without stalling (neutral). 2. Classification: Based on the transmission type, gear transmissions can be divided into three categories: two-shaft, three-shaft, and compound. The two-shaft type has two main shafts (excluding the reverse shaft) and only requires one pair of gears for speed reduction. The three-shaft type has three main shafts (input shaft, intermediate shaft, and output shaft) and requires two pairs of gears for speed reduction. The compound type consists of two transmissions connected in series or parallel to achieve more gear positions with fewer gears.

How to Determine Whether to Change the Transmission Fluid

Methods to determine whether to change the transmission fluid: When you feel that the car's gear shifting is stiff or not smooth, or there are abnormal noises from the transmission, body shaking, or slow acceleration, it indicates that the transmission fluid needs to be changed. After prolonged use, the performance of the transmission fluid will degrade, including reduced viscosity, lubrication, and sealing properties, all of which affect the operation of the transmission and, consequently, the driving experience. Transmission fluid is an oil product that keeps the gear system clean, ensuring the proper functioning of the transmission and extending the lifespan of the transmission components. Most transmission fluids can be used in automatic transmissions available on the market. In fact, each automatic transmission design has different technical requirements. Even the same model of transmission configured in different car models will have variations in torque, weight, speed, and structure. Therefore, the original manufacturer specifies its own dedicated transmission fluid. Different transmission fluids are one of the factors that affect the quality of gear shifting.

What are the clever tricks for removing license plate screws?

The clever tricks for removing license plate screws are: 1. Use a screwdriver to remove the protective cover on the screw; 2. Break the protective shell of the screw. Although the material of the protective shell is hard, it is also brittle, so you can use a screwdriver and pliers to pry off the shell; 3. After the shell is pried off, the screw will become relatively loose. At this point, you can use pliers to grip the top of the screw and slowly unscrew it; 4. If the second step fails to pry off the shell, you can first use an angle grinder to cut off both sides of the screw, making the screw head flat; 5. Use a wrench to unscrew the screw; 6. If you have a special license plate screw vise, simply use the vise to grip the screw and unscrew it directly.

Why does the Volkswagen CC engine make a ticking sound when accelerating?

The reasons why the Volkswagen CC engine makes a ticking sound when accelerating are: 1. Loose fasteners, vibration during engine operation causes certain components to loosen, resulting in impact sounds. For example, loose flywheel fixing bolts, loose connecting rod bolts, etc. can cause abnormal noises; 2. Deformation or damage of individual components, abnormal noises caused by deformation or damage of certain parts, such as knocking due to bent connecting rods, broken valve springs, or abnormal noises caused by crankshaft fractures; 3. Improper assembly adjustment or repair, resulting in incorrect component clearance, such as excessively tight piston pin assembly or improper valve clearance adjustment causing abnormal noises. The dimensions of the Volkswagen CC are 4865mm in length, 1870mm in width, 1459mm in height, with a wheelbase of 2841mm.

What are the reasons for the four-wheel drive malfunction indicator light to illuminate?

The reason for the four-wheel drive malfunction indicator light to illuminate is caused by the fuel emission system. There are three types of indicator lights: 1. Engine oil indicator light: This light is used to display the oil pressure condition inside the engine. It illuminates when the ignition is turned on during the vehicle's self-check and turns off after the engine starts. According to Yuanhang Driving School, if this light stays on, it indicates that the engine oil pressure is below the specified standard and requires maintenance. 2. Coolant temperature indicator light: This light primarily displays the temperature of the coolant in the engine. It only illuminates for a few seconds during the vehicle's self-check and remains off under normal conditions. If the coolant temperature exceeds the specified value, the vehicle should be stopped immediately for maintenance. 3. Handbrake indicator light: This light is represented by a circled 'P' letter and remains off under normal conditions. It automatically illuminates when the handbrake is engaged. Currently, only some vehicle models have a warning sound when driving with the handbrake engaged.
