How Many Kilometers Can a Car Spare Tire Run at Most?

Car non-full-size spare tires should not exceed a total mileage of 50 kilometers. Car spare tires are generally divided into full-size spare tires and non-full-size spare tires. Full-size spare tires are the same size as regular tires and have no mileage restrictions, but they must be driven at lower speeds. Below is relevant information about car spare tires: 1. Full-size spare tire: The specifications of a full-size spare tire are exactly the same as the other four tires on the vehicle, and it can replace any one tire that is temporarily or already unusable. 2. Non-full-size spare tire: The diameter and width of this type of spare tire are slightly smaller than the other four tires, and it can only be used as a temporary replacement. Moreover, it can only be used on non-driving wheels, and the maximum speed should not exceed 80km/h. 3. Run-flat tire: Run-flat tires are also known as safety tires, commonly referred to as "anti-explosion tires." Compared to ordinary tires, run-flat tires do not leak air or leak very slowly after being punctured, maintaining the driving profile, and the tire bead can remain fixed on the rim, ensuring that the car can drive to a service station for a long time or temporarily stably.

What does eco mode mean in a car?

Eco-mode refers to the economic driving mode of a car. 'Eco' is an English abbreviation derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). Eco mode is further divided into active eco driving mode and passive eco driving mode. When the eco indicator light on the dashboard illuminates, it indicates that the vehicle's economic mode has been activated. Eco mode can be categorized into active and passive types. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to activate it. When the driver presses the eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. Passive eco mode does not have a dedicated button; when the dashboard eco indicator light turns on, it merely serves as a reminder function. The eco system automatically evaluates your driving behavior, and if your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the eco indicator light. Most vehicles adopt the active eco driving mode, meaning they have a standalone switch button. Therefore, during daily driving, we can generally activate eco mode. However, it is unnecessary to enable eco mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of eco mode but also negatively impact the vehicle's power performance. Additionally, eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, causing the eco mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the eco mode will not function under these conditions either.

How Often Should the Automatic Transmission Fluid Be Changed for a Corolla?

For a Corolla, the automatic transmission fluid should be changed every 40,000 kilometers, while the manual transmission fluid should be changed every 60,000 kilometers. Below are the methods for changing the transmission fluid for a Toyota Corolla: 1. Gravity Drain: The principle is similar to changing engine oil. After loosening the tightening nut at the bottom of the oil pan, the transmission fluid will automatically drain out through the drain hole. 2. Machine Flush: New transmission fluid is added to the flushing machine, which is then connected to the transmission fluid circuit. The machine's function is to push out the old fluid with the new one, ensuring a cleaner flush of the fluid circuit. 3. Oil Pan Removal Method.

What is the difference between the internal and external air circulation modes in a car's air conditioning system?

Internal air circulation means that the air only circulates inside the car, driven by the blower to cycle the cabin air. External air circulation, on the other hand, connects the interior of the car with the outside. While driving, airflow automatically enters the cabin due to wind pressure, and when stationary, outside air can still enter the blower through the air ducts and be blown into the cabin. Below is an introduction on when to use each mode: 1. External air circulation: For a newly purchased car, it is essential to keep the external air circulation mode on as much as possible to maintain airflow between the inside and outside of the car. This helps to quickly release harmful gases from the cabin. Additionally, during long highway drives, keeping the internal air circulation mode on for too long can lead to insufficient oxygen levels in the cabin, causing driver fatigue and potentially leading to accidents. In such cases, switching to external air circulation can replenish fresh air inside the car. 2. Internal air circulation: During regular driving, we mostly use the internal air circulation mode. However, it is crucial to switch to internal air circulation during heavy traffic, as the density of exhaust fumes in the air increases with congestion. This mode effectively prevents outside exhaust from entering the cabin, protecting occupants from harm. It is also advisable to use internal air circulation during sandstorms or dusty weather, as it not only prevents dust from entering the cabin but also reduces the impact of sand on the air conditioning filter.

Where is the engine oil filler port located?

The engine oil filler port is generally located on the left side of the engine. 1. Slowly unscrew the oil filler cap in the reverse direction, open the cap, and pour in the oil. When reinstalling the oil filler cap, use the oil on the dipstick to lubricate the cap opening, then smoothly tighten it in the correct direction until it is properly seated. 2. Regarding the position for adding engine oil, the oil should be filled up to the upper limit mark on the dipstick for optimal performance. Overfilling can create excessive resistance for the engine, which may increase fuel consumption. Below are the basic steps for adding engine oil: (1) After the car has been turned off and parked for about ten minutes, pull out the dipstick and wipe the oil marks clean with a cloth. (2) Reinsert the dipstick into the dipstick tube, then pull it out again to check the oil marks. Normally, the oil marks should be between the upper and lower marks on the dipstick, slightly above the middle line. (3) If the oil marks are below the lower mark, it indicates insufficient oil, and you should add oil immediately. While adding oil, continuously pull out the dipstick to monitor the oil level. (4) When topping up the oil, try to use the same type of oil as the one already in the engine to avoid mixing different brands or grades of oil.

How to Turn Off Auto Start-Stop in a Car?

The steps to turn off the auto start-stop feature in a car are as follows: 1. Press and hold the brake pedal while the vehicle is in normal operation. 2. The auto start-stop system will activate, and the indicator light on the dashboard will illuminate. 3. Press the "off" button for the auto start-stop system. 4. The dashboard will display that the system has been turned off, indicating the auto start-stop is deactivated. Here is an introduction to the auto start-stop feature: The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light) and restarts it automatically when it's time to move forward again.
