AMT gearboxes are indeed equipped with a clutch, but their operation differs from that of traditional manual gearboxes. This automated clutch manual transmission adopts an integrated electro-mechanical-hydraulic design. It controls the disengagement and engagement of the clutch via a hydraulic pump, while an electronic control module monitors parameters such as vehicle speed and throttle opening in real time to automatically complete gear shifting operations. Drivers do not need to operate the clutch pedal, as the automatic clutch integrated inside the gearbox works independently during starting and gear shifting. Its structure retains the gear set of a manual gearbox, but automation is achieved through motor-controlled pneumatic, hydraulic, or electric systems. The advantage of AMT lies in combining the high transmission efficiency of manual gearboxes (over 7% higher than AT) and the operational convenience of automatic gearboxes, while reducing fuel consumption by approximately 20%. However, it should be noted that a slight jolt may occur during hill starts due to the response characteristics of the hydraulic system, which is caused by its mechanical structure. Currently, some economy models in the local market adopt this type of gearbox, and their maintenance costs are about 30% lower than those of traditional automatic gearboxes.

In the Malaysian market, Toyota and Honda products stand out particularly for the reliability of their automatic transmission models. As representatives of B-segment sedans, the Toyota Vios and Honda City have long dominated the reliability rankings, owing to their mature powertrains, low failure rates, and extensive service networks. The CVT or conventional automatic transmission technologies used in these models have been proven in the market for years, with maintenance costs kept at approximately 300 to 500 Malaysian ringgit per month, and their resale value retention rates reaching as high as 60% to 70%. Additionally, while the Toyota Hilux is a pickup truck, the durability of its 6-speed automatic transmission is widely recognized in commercial applications, particularly in high-temperature and rainy climates. Notably, as a local model, the Perodua Myvi's D-CVT transmission excels in urban commuting scenarios, exhibiting a failure rate below the segment average, coupled with a manufacturer-provided 5-year/150,000-kilometer warranty, delivering outstanding cost-performance. When selecting an automatic transmission model, it is advisable to prioritize Japanese models equipped with naturally aspirated engines for their superior powertrain integration, while also considering the scope of the manufacturer's maintenance package to minimize long-term ownership costs.

The windshield wiper symbol is a graphic sign on the vehicle's control panel or lever that identifies the wiper function. The front wiper symbol typically features a fan-shaped design with slanted lines on the left and a water spray line in the middle, vividly illustrating the wiping action and water spray function. The rear wiper symbol, on the other hand, uses a rectangular design, also with slanted lines and a water spray line, to match the shape of the rear windshield. These symbols are designed to be intuitive, allowing drivers to quickly recognize and operate them, ensuring clear visibility through the front and rear windshields when driving in rainy or snowy weather or on muddy roads. The operating modes of windshield wipers include the traditional intermittent mode and the sensor-based automatic mode. The latter automatically adjusts the wiping frequency via sensors, enhancing user convenience. In daily use, maintenance is essential: avoid dry wiping, regularly check the condition of the wiper blades, and clear ice from the windshield first in winter to extend the wiper's lifespan and ensure driving safety.

Cars are equipped with two windshield wipers mainly to meet the cleaning needs of the front and rear windshields under different driving conditions. The two wipers on the front windshield feature a symmetrical design, covering a larger cleaning area to effectively remove rainwater and debris, ensuring a clear forward view for the driver. The necessity of a rear wiper depends on the vehicle design: sedans (three-box cars) typically do not require a rear wiper as the airflow generated by their streamlined bodies naturally cleans the rear window; whereas hatchbacks, SUVs, and station wagons, with their vertical rear designs that create airflow vortices, tend to accumulate dust and rainwater, thus requiring rear wipers to maintain rear visibility. This design variation demonstrates engineers' balanced consideration of aerodynamics and practicality, ensuring safe driving across different vehicle types in various weather conditions. Additionally, proper wiper maintenance is essential—avoid dry operation or aggressive removal of stubborn debris to prolong their service life.

There is no fixed standard for the replacement frequency of windshields; it needs to be comprehensively assessed based on actual usage conditions. Typically, if a vehicle has been in service for 10 years or has exceeded 200,000 kilometers in mileage, replacement may be necessary due to natural aging that results in reduced transparency or minor deformation. However, in cases of structural damage—such as cracks longer than 20-25 millimeters, cracks extending to the edge that compromise sealing integrity, or damage and deformation caused by impacts—immediate replacement is required to ensure driving safety. For routine maintenance, it is advisable to inspect the windshield condition every 6 to 12 months, avoid impacts from hard objects and prolonged sun exposure, and use high-quality glass cleaners along with UV-protective films to slow aging. Note that minor cracks may propagate due to vehicle vibrations or temperature fluctuations; even if they initially do not impair visibility, prompt attention is recommended. Professional repairs are only suitable for localized damage; in most scenarios, replacing the windshield entirely is the more prudent choice. As a critical component of a vehicle's passive safety system, the windshield's integrity directly influences airbag deployment effectiveness and roof crush resistance during collisions. Thus, any identified issues should be addressed by certified technicians using OEM-specification glass to guarantee precise installation and proper sealing.
