Toyota Vios uses Denso spark plugs from Japan, with the model number C16HR-U11 and a heat range of 5, which are high-end products from Denso. Here are the specific details about spark plugs: 1. Spark plugs, commonly known as sparkers, function to discharge the high-voltage pulses sent through the high-tension leads, breaking down the air between the spark plug electrodes to generate an electric spark that ignites the air-fuel mixture in the cylinder. 2. The main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. 3. The purpose of a spark plug is to introduce tens of thousands of volts of high voltage into the combustion chamber and generate an electric spark to ignite the air-fuel mixture. Working in conjunction with the ignition system and fuel supply system, it significantly determines the engine's performance.

Introduction to Toyota Corolla Function Buttons?

Corolla function button introduction is as follows: Electronic Stability Program (ESP): It can effectively prevent body sideslip, fishtailing, and other loss of control situations. Generally, it is not recommended for drivers to manually turn it off. Parking Radar/Image: This button activates the panoramic image and radar function, providing drivers with alerts and visual feedback to detect surrounding obstacles. Internal/External Circulation: Internal circulation refers to heating or cooling the air inside the car and then sending it back into the car, while external circulation allows outside air to enter the car. Use internal circulation in environments with heavy exhaust fumes, dust, or smog during traffic jams. On highways, it is advisable to switch from internal to external circulation periodically, with internal circulation preferably not exceeding one hour.

What are the symptoms of poor car battery contact?

Poor contact in a car battery can lead to unstable idling, damage to the battery, and may also cause harm to the generator. Here are some tips for car battery maintenance: 1. Electrolyte level: Always keep it between max and min. Check monthly and add distilled water (pure water) as needed based on the level reduction. Never add acid. 2. Insufficient voltage: When the battery voltage is low and the lights are dim or the engine struggles to start, perform an external charge immediately. 3. Avoid overcharging or prolonged power loss: Overcharging can cause active material to fall off, while power loss can lead to plate sulfation. Ensure the regulator voltage is neither too high nor too low. 4. Regularly check if the vent hole is clear: To prevent battery deformation or explosion. 5. Keep the battery away from heat sources and open flames: Ensure proper ventilation when using a charger to avoid burns or injuries.

What Does the Car Number Mean?

Car number, also known as engine number, consists of four main parts. It serves to facilitate the production management and usage of engines, and is an identification code assigned by engine manufacturers to a batch of identical products in accordance with relevant regulations, corporate or industry practices, and engine attributes. The specific meanings are as follows: 1. The prefix includes product series code, generation symbol, and regional or corporate code. Manufacturers can choose corresponding letters as needed, but these must be approved and filed by the industry standard regulatory body. 2. The middle part consists of symbols for the number of cylinders, cylinder arrangement type, stroke, and cylinder diameter. 3. The rear part includes symbols for structural features and usage characteristics. 4. The suffix is a distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same product series, manufacturers may select appropriate symbols to indicate this, with the rear part and suffix separated by a "-".

How often should a vehicle be inspected after 6 years?

For the first six years, cars require an inspection every two years. After six years, it becomes an annual inspection, and after fifteen years, it switches to a semi-annual inspection. Below are the inspection standards for different vehicle types: 1. Exemption Policy: Non-commercial passenger cars (including non-commercial sedans, small and micro passenger vehicles, excluding vans and vehicles with 7 or more seats) are exempt from inspection for the first six years. "New vehicles within six years are exempt from on-site inspection," requiring only an inspection sticker application every two years. Privately owned vehicles registered after September 2012 that meet the conditions can enjoy this exemption policy, with an annual inspection thereafter. From 6 to 15 years, an on-site inspection is required once a year, and after 15 years, it becomes once every six months. 2. Commercial passenger vehicles must be inspected annually within the first five years and every six months thereafter. 3. Large commercial trucks and large/medium non-commercial passenger vehicles require an annual inspection within the first ten years and every six months thereafter. 4. Motorcycles must be inspected every two years within the first four years and annually thereafter.

What Technologies Are Required for Autonomous Driving?

Autonomous driving requires the following key technologies: 1. AEB (Autonomous Emergency Braking): AEB refers to a technology that enables a vehicle to automatically brake when encountering sudden hazards or when the distance to the preceding vehicle or pedestrian is less than the safe distance, thereby avoiding or reducing rear-end collisions and enhancing driving safety. This operates without adaptive cruise control. 2. ACC (Adaptive Cruise Control): ACC effectively assists drivers in coordinating steering and braking. While conventional cruise control is considered Level 1 autonomous driving, ACC qualifies as Level 2. 3. LDW (Lane Departure Warning): This system detects road markings to predict lane departures and alerts the driver. 4. TJA (Traffic Jam Assist): TJA integrates full-speed-range adaptive cruise control with automatic following functionality and full-speed lane-keeping assistance. 5. HWA (Highway Assist): Recognized as a representative Level 2.5 autonomous driving feature, HWA not only assists drivers in automatic lane-keeping but also enables lane changes upon driver command (via turn signal activation) when safe conditions are met. Additional technologies include: Lane Change Assist, Adaptive Light Control, Automatic Parking System (AP), and Traffic Sign Recognition (TSR).
