Carrera tires are from the Carrera brand. Below are the precautions for tire maintenance: Regularly check the tread: The thickness of the tire tread affects the tire's grip, drainage capability, etc. Regularly inspecting the tread thickness is very important. You can check it using the tread thickness indicator blocks on the tire itself or with a tread depth gauge. Generally, when the tread depth is less than 3mm, caution should be taken, and when it is less than or equal to 1.6mm, the tire should be replaced immediately. Regularly measure tire pressure: Just maintain the tire pressure at the recommended value in the manual. If it is too high or too low, it can be adjusted accordingly.

What does the ECON button mean in Honda cars?

ECON stands for the car's fuel-saving mode switch. This button can turn the fuel-saving mode on or off. Modern cars generally offer three driving modes to choose from: fuel-saving mode, comfort mode, and sport mode. Below is information about these three modes: Fuel-saving mode: When the car is in this mode, fuel consumption is relatively low. The throttle pedal sensitivity decreases, and the transmission shifts up more aggressively. Comfort mode: This mode can be considered a normal operating mode for the car. In this mode, the throttle pedal response is more sensitive than in fuel-saving mode. Sport mode: Sport mode can be used during aggressive driving. After activating sport mode, the throttle pedal response becomes very sensitive, and the transmission delays shifting. The transmission will only upshift after the engine speed reaches the redline zone. After switching to sport mode, the engine speed is maintained at around 3,000 RPM, ensuring better power response during acceleration. When the car enters ECON mode, it achieves reduced fuel consumption and energy savings, but the car's power output weakens. ECON can be understood as an abbreviation for "economy." In most situations, it is recommended to keep ECON mode on. Only when high torque output is needed (e.g., climbing hills) or when driving at very high speeds should ECON mode be turned off. Pressing the ECON button activates a low-carbon, eco-friendly driving mode. The ECU, engine, and transmission then intelligently execute the driver's intentions in the most fuel-efficient manner, achieving optimal fuel economy through quick upshifts and smooth acceleration. The idle state also operates in an energy-saving mode. When the driver presses the throttle pedal deeply, the ECON system effectively controls the opening and closing of the intake valves to ensure smooth engine operation and energy savings. Although ECON mode is simple and effective to operate, it cannot function under certain conditions: When the vehicle speed exceeds 120 km/h, priority is given to speed, and the fuel-saving mode automatically deactivates. This means that if the car exceeds the economical speed range (typically between 60-90 km/h), ECON mode will not save fuel. The key to ECON mode is its reliance on computer-controlled independent operation while the car is moving. Therefore, it does not work during idle stops, in N or P gear, or in manual mode. When overcoming significant resistance or requiring high torque output—such as when climbing hills—the ECU prioritizes ensuring sufficient power to drive the car, and ECON mode will not function in such cases.

What is the actual fuel consumption of the BMW 740?

The BMW 740 has six models currently on sale. Among them, the 2021 740Li Executive Luxury Package, Leading M Sport Package, and Leading Luxury Package, all equipped with a 340-horsepower engine, have an NEDC fuel consumption of 7.5L per 100 km. The 2021 740Li xDrive Executive M Sport Package, Luxury Package, and the modified 740Li xDrive Brilliance Custom Limited Edition, also equipped with a 340-horsepower engine, have an NEDC fuel consumption of 7.9L per 100 km. The fuel tank capacity of different BMW 740 models is the same. The distance that can be covered with a full tank of fuel is as follows: For models equipped with a 340-horsepower engine and an NEDC fuel consumption of 7.5L per 100 km, the fuel tank capacity is 78L, and the distance that can be covered with a full tank is 78/7.5*100=1040 km. For models equipped with a 340-horsepower engine and an NEDC fuel consumption of 7.9L per 100 km, the fuel tank capacity is 78L, and the distance that can be covered with a full tank is 78/7.9*100=987 km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase a car's fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily during cold starts, requiring more gasoline to be injected for combustion, thus increasing fuel consumption. Additionally, at low temperatures, the engine's computer controls higher RPMs to warm up the car, which also increases fuel consumption.

What are the differences between the C2 and C1 driving test subjects?

The differences between the C2 and C1 driving license test subjects are: Subject 2: The C2 test does not include the slope parking project in Subject 2 because it is for automatic transmission vehicles, which means one fewer test item compared to manual transmission vehicles. Subject 3: The C2 test does not involve gear shifting operations in Subject 3, as there are no manual transmission gears. The test vehicles for C2 and C1 are different. The driving license test is conducted to obtain a motor vehicle driving license, with unified test subjects and passing standards nationwide. Both C1 and C2 driving tests consist of four subjects: theoretical knowledge (Subject 1), field driving skills (Subject 2), road driving skills (Subject 3), and civilized driving theoretical knowledge (commonly known as Subject 4). The specific test subjects are as follows: Subject 1: Mainly tests basic road traffic knowledge. Subject 2: Mainly tests reversing into a garage, parallel parking, slope parking (not applicable for C2), starting, right-angle turns, and curve driving. Subject 3: Mainly tests 16 driving skills, including vehicle preparation, starting, and straight-line driving. Subject 4: Mainly tests safe and civilized driving operation requirements, similar to Subject 1, it is a theoretical test. Subject 2 test deduction items: Not wearing a seatbelt: deduct 100 points; Starting the engine without the gear in neutral: deduct 100 points; not using turn signals (including starting, lane changing, overtaking, turning, and parking by the roadside); Turn signals not used for more than 3 seconds; forgetting to turn off turn signals or incorrect use of turn signals: deduct 10 points; engine stalling once: deduct 10 points; wheels touching the edge line: deduct 100 points; Stopping for more than 2 seconds: deduct 5 points; not following the prescribed route or sequence: deduct 100 points; failing to reverse into the garage: deduct 100 points; vehicle body crossing the line: deduct 100 points. Subject 3 test deduction items: Not walking around the vehicle to inspect its appearance and surroundings: fail; Not observing traffic conditions before opening the door: fail; Starting with insufficient brake pressure: fail; Starting with the door not fully closed: fail; Not observing the interior and exterior rearview mirrors or turning the head to observe traffic conditions before starting: fail; Starting the engine without the gear lever in neutral (parking gear): fail; Starting without releasing the parking brake and not correcting in time: fail; Starting without releasing the parking brake but correcting in time: deduct 10 points; Not releasing the starter switch promptly after starting the engine: deduct 10 points; Vehicle jerking during starting: deduct 5 points; Improper control of the accelerator pedal during starting, causing excessive engine speed: deduct 5 points.

What is the Difference Between Honda's Independent Badge and Joint Badge?

The differences between Honda's independent badge and joint badge are as follows: 1. Trademark royalty: Independent badge models use the HONDA trademark and require higher patent fees, whereas joint badge models no longer use the HONDA trademark and thus do not incur trademark royalty costs. 2. Manufacturing cost: Joint badge models adopt the R&D system of joint venture factories, effectively shortening the production timeline, while independent badge models have a longer production process, resulting in significantly lower costs for joint badge models compared to independent badge models. 3. Production standards: Independent badge models follow Japanese production standards, whereas joint badge models adhere to domestic production line standards.

Can a Flooded Car Still Be Driven After Being Submerged?

If handled properly, the car can still be driven normally in the future. Here are the specific details: Vehicle water wading process: If the engine stalls, immediately turn on the hazard lights, shut off the engine, and turn off the ignition. Do not attempt to restart the engine, as doing so can easily cause fatal damage to the engine. Such secondary damage caused by human intervention will not be covered by either the vehicle damage insurance or the water submersion insurance. Parking lot flooding: When a vehicle is submerged while stationary in an underground garage or parking lot, lock the vehicle and do not attempt to start the engine. Try to seal the vehicle as much as possible.
