Here are several reasons why the alarm may sound after locking the car: 1. Issue with the hood latch button: If there's a problem with the two small buttons near the front hood, adjusting the hood upwards can resolve this issue. 2. Damaged sensor button: If the sensor button on the driver's side door is damaged, it needs to be inspected and replaced at a 4S shop. 3. Malfunctioning alarm system: If the alarm system is malfunctioning, it is recommended to deactivate the alarm and investigate the root cause of the alarm trigger, checking each possibility one by one. Note: Generally, if the vehicle alarm cannot detect the front sensor or if the front sensor sends an alarm signal, the vehicle alarm will subsequently sound.

What does 10w-40 mean for engine oil?

10w-40 refers to the SAE standard viscosity value of the engine oil. Here are the relevant explanations: 1. The number after W represents the kinematic viscosity of the oil at 100℃. The higher the number, the higher the viscosity. 2. The oil grade includes two parts: classification and viscosity specification. The oil grade usually indicates viscosity and quality. 3. W stands for winter. The smaller the number before it, the better the low-temperature fluidity of the oil, indicating a lower usable environmental temperature and better protection for the engine during cold starts. The number after "W" (after the hyphen) is an indicator of the oil's high-temperature resistance. The larger the number, the better the oil's protective performance at high temperatures.

How to Clear a Clogged Exhaust Pipe?

From a design perspective, exhaust pipes cannot be cleaned; severe blockages require complete replacement. Effects of a clogged exhaust pipe: 1. Insufficient power, slow acceleration: Exhaust gases cannot exit, and fresh air cannot enter, leading to inadequate combustion and reduced power. 2. Increased forced downshifts in automatic transmission vehicles: A clogged exhaust pipe reduces engine power, prompting the driver to press the accelerator. However, the ECU will automatically force the transmission to downshift based on the throttle position. 3. Difficulty starting the engine: Even with a charged battery, proper fuel injection, and normal compression pressure, the engine may fail to start because fresh air struggles to enter. 4. Rattling noises from the exhaust system during hard acceleration or emergency braking. In most cases, the primary cause of exhaust pipe blockage is a neglected catalytic converter. Maintenance of the catalytic converter: 1. Use unleaded gasoline: The catalytic converter is highly sensitive to lead. Leaded gasoline can cause blockages. 2. Regular maintenance: Clean the throttle body every 10,000 kilometers. If performance remains poor after cleaning, the catalytic converter may need cleaning.

What causes the car to shake when accelerating?

The reasons why the car shakes when accelerating are as follows: 1. It may be due to unstable engine operation, and carbon deposits should be cleaned. 2. If the steering wheel shakes, check whether the cooling fan is loose or has other issues, as well as the ball joints and tie rod ends. After inspection and replacement, a four-wheel alignment should be performed; otherwise, the gear may not engage. 3. Check the engine mounts: Inspect the engine mounts and the installation of the air conditioning compressor for any looseness. 4. Low idle speed may also be caused by the engine not receiving the air conditioning activation signal, or the air conditioning activation signal voltage may be too weak to increase the engine speed, leading to engine shaking under heavy load.

What type of engine oil should be used for Toyota RAV4?

Toyota RAV4 is recommended to use semi-synthetic engine oil and full-synthetic engine oil. Here is some information about engine oil: 1. There are three types of engine oil used in vehicles: mineral oil, semi-synthetic oil, and full-synthetic oil. 2. Different types of engine oil have different effects, varying degrees of protection for the engine, and different usage cycles. 3. The usage cycle of mineral oil is about 5,000 kilometers, semi-synthetic oil is about 6,500 kilometers, and full-synthetic oil is about 10,000 kilometers.

Is Transmission Fluid Universal?

Transmission fluid cannot be mixed or used universally, as each type has its own specialized oil that must correspond to the appropriate transmission. There are three types of automatic transmissions: AT (hydraulic mechanical transmission), CVT (continuously variable transmission), and dual-clutch transmission. These transmissions differ in structure and working principles, and the transmission fluids they use also vary significantly. Details are as follows: 1. CVT Transmission Fluid: The nature of CVT transmission fluid is similar to AT fluid, but it is also a specialized oil. Since CVT transmissions use unique steel chains for power transmission, parameters such as fluid flow rate, friction performance, and expansion coefficient differ, making AT transmission fluid unsuitable as a substitute. 2. Dual-Clutch Transmission Fluid: In dual-clutch transmissions, there are two types of oil—one is ordinary gear oil for lubricating gears, similar to standard manual transmission fluid but with better performance, and the other is oil used for the control system, which is the same as ATF. 3. Hydraulic Mechanical Transmission Fluid: Hydraulic mechanical transmissions are automatic transmissions, and the oil they use is referred to as ATF. It is a specialized fluid added to the transmission to serve functions such as power transmission, lubrication, and heat dissipation.
