Toyota hybrids currently use nickel-metal hydride (NiMH) batteries, which employ a strategy of shallow discharge and frequent refreshing. Theoretically, the battery lifespan can exceed eight years or even longer. However, Toyota offers an 8-year/200,000-kilometer warranty for its hybrid battery, indicating the company's strong confidence in NiMH batteries. Below are some car battery maintenance tips: 1. Avoid prolonged vehicle inactivity: The battery installed in the car will self-discharge during extended periods of inactivity. It's best to drive the vehicle at least once a week for a minimum of 20 minutes to allow the battery to recharge while driving. 2. Close windows before turning off the engine: The power windows and sunroof operate using battery power. Therefore, it's advisable to close all windows before shutting off the engine, rather than after, or using the long-press lock button method after leaving the vehicle. 3. Maintain battery cleanliness: Regular inspections are an effective way to extend car battery life. Use a professional battery terminal brush or an old toothbrush to clean dust and corrosion from the positive and negative terminals. Apply petroleum jelly or grease to the contact surfaces to create a protective film.

Is it serious if the car didn't stall when driving through water?

There is basically no impact. The following is a related introduction about vehicle wading: Introduction to vehicle wading: As the name suggests, vehicle wading refers to driving through water on low-lying, waterlogged roads. This usually occurs in rainy weather when poor drainage leads to water accumulation in low-lying road sections. Precautions for vehicle wading: Before wading, observe the road conditions carefully; maintain stable power while in water; after wading, check the electrical system. If a car stalls in water, the main reason is water entering the exhaust pipe, and in some cases, there may also be electrical damage. Once the car stalls, do not attempt to restart it, as this may cause water to enter the intake manifold and damage the valves, potentially leading to severe engine damage. Instead, the car should be towed to a 4S shop immediately for professional handling.

How to Solve the Squeaking Noise from Plastic Interior Trim?

Squeaking noise from plastic interior trim can be resolved by: adding a layer of velvet cloth strip in the gaps, installing rubber strips between the dashboard and windshield gap can also reduce some noise. It's important to note that repeated disassembly and reassembly of the interior can also cause squeaking, so first check if there are any loose or fallen wiring harnesses or small parts causing the issue. Below is an introduction about car interior: Definition: Car interior mainly refers to the automotive products used for internal modifications, covering all aspects of the car's interior, such as steering wheel covers, seat cushions, floor mats, car perfumes, hanging accessories, interior decorations, storage boxes, etc. Status: The car interior system is a crucial part of the vehicle body, and the design workload of the interior system accounts for over 60% of the total vehicle styling design workload, far exceeding the exterior design, making it one of the most important parts of the vehicle body.

Will the Car Be Damaged If Water Gets into the Trunk?

Water in the trunk can have a significant impact on the car, and failure to address it promptly may lead to malfunctions. Below is a detailed explanation: Dangers of water entering the trunk: It can easily cause rust in the trunk, and in severe cases, perforation may occur. The spare tire is placed in a lower position inside the trunk, making it prone to water accumulation if water enters. Moisture and water cannot be drained, which can easily cause the car's interior parts to become damp, moldy, or rusty. How to handle water in the trunk: Drain the water as soon as possible. There is a rubber plug at the bottom of the spare tire compartment in the trunk; removing it allows the water to drain. Quickly locate the entry point of the water, check if the trunk lid is deformed, or if the surrounding seals are damaged. Open the lid to ventilate, remove the trunk lining and items inside, and leave the lid open to dry for about an hour to prevent mold and rust.

Is it a problem if there is water under the car seat?

If there is water under the car seat, it is recommended to check whether the air conditioning pipe of the car is leaking. Generally, problems with the car's air conditioning pipe can cause such a phenomenon. Here are some reasons for water inside the car: Rainwater entering through the windshield: It is possible that the windshield was not closed properly, allowing rainwater to enter during rainy weather, resulting in water under the seat. Make sure to close the windows properly to avoid water ingress. Poor door sealing: If the rubber seals are not installed correctly, repeated closing and squeezing of the doors can cause the seals on both sides to deform, leading to poor sealing of the car. In severe cases, this may even cause water to enter the car during rain. Sunroof leakage: The sunroof is sealed with a rubber seal. During use, it is important to pay attention to dust prevention for the seal, especially in winter or after long-distance travel. Regularly clean the seal with a duster. Additionally, it is crucial not to force open the sunroof when it is frozen, as this can damage the sunroof motor.

Will the car battery die if the car is not driven for a month?

Will the car battery die if the car is not driven for a month? The answer is yes. Here are the factors that affect battery discharge. Factors related to parking duration: The duration a battery can be left unused depends on its self-discharge rate. Due to inherent impurities in battery materials, power loss occurs whether the battery is in use or not. At room temperature, approximately 1% of charge is lost per day. When installed in a vehicle, the battery supplies current to maintain vehicle functions such as the central control computer and central door locks even when stationary. This standby current is referred to as "parasitic drain," and its magnitude varies depending on the vehicle's configuration. Other factors: High-end vehicles feature automatic wake-up functions. When activated by external influences, the current can reach several amperes and may take several minutes to return to sleep mode. The battery voltage level is not the sole determinant of whether the vehicle can start; it is also directly related to the vehicle's condition and ambient temperature.

Should motorcycle maintenance be done personally or at a shop?

Motorcycle maintenance can be handled either personally or at a shop, and those with strong hands-on skills can do it themselves. Below are the relevant details about motorcycle maintenance: Changing engine oil and oil filter: For newly purchased motorcycles, the break-in period is 2,000 kilometers. The engine oil should be changed once at 500 kilometers and again at 2,000 kilometers. After the break-in period, the oil should be changed every 2,000 kilometers during normal operation. Replacing the air filter element and routine inspections: The air filter element should be cleaned once a year. Daily maintenance includes keeping the vehicle clean, maintaining proper tire pressure, and ensuring the battery is fully charged.
