Can You Still Drive When BMW Warns of Low Engine Coolant?

When BMW warns of low engine coolant, you should not continue driving. Operating the vehicle with insufficient coolant can lead to elevated engine temperatures, potential engine damage, and reduced engine lifespan. Therefore, when the vehicle alerts you to low coolant levels, it is essential to safely pull over, add coolant promptly, and schedule an inspection and repair at a BMW service center. Coolant should be replaced every 2 to 3 years or every 40,000 kilometers. When selecting coolant, ensure its freezing point is approximately 10 degrees Celsius below the lowest environmental temperature. In addition to its antifreeze properties, coolant also serves functions such as corrosion prevention, boiling resistance, and scale inhibition. The BMW X5 is BMW's first four-wheel-drive SUV model, with dimensions of 4930mm in length, 2004mm in width, 1776mm in height, and a wheelbase of 2975mm.

What is ACC Adaptive Cruise Control?

ACC adaptive cruise control is an intelligent automatic control system, developed on the basis of the existing cruise control technology. During vehicle operation, the distance sensor installed at the front of the vehicle continuously scans the road ahead, while the wheel speed sensor collects speed signals. Adaptive cruise control, also known as active cruise control, is similar to traditional speed cruise control. The system includes a radar sensor, digital signal processor, and control module. When the distance to the vehicle ahead becomes too small, the ACC control unit can coordinate with the anti-lock braking system and engine control system to apply appropriate braking to the wheels and reduce the engine's output power, ensuring that the vehicle maintains a safe distance from the vehicle ahead.

Can the rear seats of the Tiggo 8 be folded flat?

The rear seats of the Tiggo 8 can be folded flat. First, adjust the height of the rear seat headrests and remove them if necessary. Then, stow away the rear seat safety belts. Use your hand to pull the unlocking handle at the top of the backrest to unlock it, then pull the backrest forward and lay it down. After folding, the backrest will be level with the trunk carpet. The Chery Tiggo 8 is positioned as a mid-size SUV and is set to become the flagship SUV in the future. The vehicle measures 4700mm in length, 1860mm in width, and 1746mm in height, with a wheelbase of 2710mm. In terms of power, the car is equipped with two engines: a 1.5-liter turbocharged engine and a 1.6-liter turbocharged engine.

Why is 98-octane gasoline being discontinued?

98-octane gasoline has not been discontinued. Not all vehicles can use 98-octane gasoline; it is typically reserved for high-end cars, while regular vehicles can use 95 or 92-octane gasoline. Therefore, not every gas station carries 98-octane fuel, making it less common. 98-octane gasoline refers to fuel with an octane rating equivalent to a mixture of 98% isooctane and 2% n-heptane. The advantages of 98-octane gasoline are summarized as "two highs and two lows": higher anti-knock performance and power output, along with lower harmful substances and reduced exhaust pollution. For engines with high compression ratios, high-octane gasoline is recommended. Using low-octane gasoline in such engines can lead to abnormal combustion, causing knocking, increased fuel consumption, and reduced performance. Compared to other gasoline grades, 98-octane gasoline offers stronger anti-knock properties and higher combustion efficiency, delivering superior power. However, due to its higher grade and price, it is often referred to as "premium gasoline" and is primarily used in luxury vehicles. Standards: The government imposes strict standards on automotive gasoline. These standards not only require a certain octane rating (commonly known as the gasoline grade) but also regulate the chemical composition of gasoline. If the olefin content is too high, incomplete combustion can occur, leading to the formation of gummy deposits in the intake manifold and valve guides. When selecting gasoline grades, factors such as engine operating conditions, altitude, and atmospheric pressure must also be considered. Engines frequently operating under high load, high torque, and low-speed conditions (e.g., towing vehicles) are prone to knocking and should use higher-octane gasoline (compared to vehicles under normal conditions). In high-altitude regions, due to lower atmospheric pressure and thinner air, the tendency for engine knocking decreases, allowing for the use of lower-octane gasoline. Experience shows that for every 100m increase in altitude, the required octane rating can be reduced by approximately 0.1 units. Note: Vehicles with fuel-injection systems generally have compression ratios above 8.0. Imported vehicles labeled as suitable for China's conditions can usually use leaded gasoline; otherwise, they are designed for unleaded gasoline. Generally, the higher the gasoline grade, the higher the octane rating 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. Recommendation: Using higher-octane gasoline in vehicles designed for lower grades will not cause damage, but the increased octane rating alters the fuel's ignition point, potentially leading to delayed combustion. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. Recommendation: Using lower-octane gasoline in high-grade vehicles can cause engine knocking. Since the octane rating is significantly lower, the fuel may ignite prematurely during the compression stroke before the spark plug fires. This premature ignition creates resistance during the upward stroke, leading to unstable engine operation. Mild knocking may only increase noise without significant engine damage, but severe knocking indicates serious engine issues, affecting driving stability and causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring.
