What does ECO mean on an automatic transmission car?

ECO in an automatic transmission car refers to the Economic Driving Mode. ECO is an English abbreviation derived from the words Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active 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 is categorized into active and non-active types. The difference lies in the fact that the active type has a dedicated button, allowing the driver to choose whether to enable 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. The non-active ECO mode does not have a dedicated button. When the dashboard ECO indicator light turns on, it serves merely as a reminder function. The ECO system automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most cars employ the active ECO driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, we can generally enable the ECO mode. However, it is unnecessary to activate 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 affect the vehicle's power performance. Additionally, the 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, the 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 in such scenarios.

Why does the Corolla's dashboard red light flash after locking the car?

After locking the car, the red light flashing on the dashboard indicates that the vehicle has entered the anti-theft state, and the anti-theft system is functioning normally. Here is more information about the 2021 Corolla: 1. Exterior: The new Corolla features a more aggressive design that caters to the aesthetic standards of today's young consumers. The front fascia adopts a honeycomb design, giving it a dynamic look. The emblem and the grille on both sides use a continuous design, which not only enhances the sense of refinement but also improves the overall unity of the front face, creating a sharp visual effect. 2. Interior: The new Corolla sedan version is expected to be similar to the hatchback version, equipped with a three-spoke steering wheel and a digital instrument panel, offering a high-tech feel. The layout of the center console is highly layered, featuring a popular floating touchscreen that is not only eye-catching but also supports the navigation system. Below the touchscreen are the air conditioning controls, which use rotary knobs for convenient operation. 3. Features: The new Corolla comes with the latest Smart Connect System and Safety Sense system, including popular features such as Apple CarPlay and the Entune 3.0 audio system. Safety is also a major focus of the vehicle, equipped with the Toyota Safety Sense suite, which includes lane keeping assist, lane departure warning, automatic high beams, and a pre-collision system with pedestrian detection.

Can the Cadillac CT5 use 92 octane gasoline?

According to the official vehicle manual recommendation, the Cadillac CT5 should use 95 octane gasoline. In addition to checking the suitable gasoline grade in the vehicle manual for the Cadillac CT5, you can also find this information on the fuel tank cap, which will also indicate the recommended grade. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of some new technologies, the gasoline grade cannot be solely determined by the compression ratio. High compression ratio engines can also be tuned to use lower octane gasoline. This is because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane number, and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Cadillac CT5 occasionally uses the wrong gasoline grade, simply switch back to the correct grade after the current tank is used up. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed ignition in the engine. This means the engine's power output and thermal efficiency will decrease, resulting in poorer performance as experienced by the driver. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane number is significantly lower, the gasoline's ignition point decreases, causing it to ignite prematurely during the compression stroke. If the fuel ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance will make the engine run very unstably. If it's mild knocking, it only increases noise and does not cause significant damage to the engine. However, if there is noticeable knocking, it indicates severe engine conditions. The vibrations not only affect driving stability but can also cause abnormal wear on the pistons and cylinders, and in severe cases, even cylinder scoring.

Is the correct sequence for adding fuel additive to fill up the tank first or add the additive first?

The correct sequence for adding fuel additive is to add the additive first and then fill up the tank. Fuel additive, commonly known as fuel system cleaner or gasoline additive, serves the following functions: 1. Remove carbon deposits; 2. Improve atomization; 3. Protect the engine; 4. Reduce engine wear; 5. Eliminate black smoke and lower emissions. Precautions for using fuel additives include: 1. Pay attention to purchasing branded fuel additives and avoid randomly using those recommended by repair shops; 2. New cars should not rush to use fuel additives; 3. Do not rely solely on fuel additives to clean engine carbon deposits—driving habits should also be taken into consideration.

What to Pay Attention to When the Engine Water Temperature is Too High?

When the engine temperature is too high, pay attention to the following: 1. Check and replenish the coolant, as insufficient coolant is the main cause of high engine water temperature; 2. Clean the dirt inside the radiator; 3. Check if the water pump is functioning properly. The water pump is the power source for coolant circulation. If the water pump is damaged, the coolant cannot circulate to dissipate heat, leading to high water temperature. When the vehicle's water temperature is too high, do not immediately turn off the engine. For most models, the cooling system's water pump is driven by the engine. Turning off the engine will also stop the water pump, preventing the coolant from continuing to circulate. At this time, all parts of the engine remain at high temperatures. Without effective cooling, the engine may be damaged.
