Should the Volkswagen Bora use 92 or 95 gasoline?

According to the official car manual recommendation, the Volkswagen Bora should use 92 gasoline. In addition to checking the suitable gasoline grade in the car manual, you can also check the fuel tank cap, which will also indicate the recommended gasoline grade. Usually, the gasoline grade can also be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should choose 92 gasoline, while those with a compression ratio between 10.0-11.5 should choose 95 gasoline. However, with the use of some new technologies, the gasoline grade cannot be determined solely by the compression ratio. A high compression ratio can also be adjusted to use low-grade gasoline 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 gasoline contains 92% isooctane and 8% n-heptane, while 95 gasoline contains 95% isooctane and 5% n-heptane. If the Volkswagen Bora occasionally uses the wrong gasoline grade, simply switch back to the correct grade after using it up. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use low-grade gasoline, using high-grade gasoline by mistake will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use high-grade gasoline, using low-grade gasoline can cause engine knocking. Because the octane number is too low, 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 is mild knocking, it will only increase noise and cause minimal damage to the engine. However, if there is noticeable knocking, it indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on the pistons and cylinders, and in severe cases, cylinder scoring.

Is the Transmission of the 2013 LaCrosse Made by Aisin?

The transmission of the 2013 LaCrosse is manufactured by Aisin. Established in 1969, Aisin is a world-renowned professional developer and manufacturer of automotive automatic transmissions. In the field of automotive automatic transmissions, Aisin's products hold the highest market share globally. The 2013 LaCrosse is equipped with a 6-speed automatic manual transmission. Essentially, an automatic manual transmission is a traditional AT or CVT transmission with added manual shifting functionality. The purpose of this design is to enhance the driving pleasure of automatic transmission vehicles. When using the transmission of the 2013 LaCrosse in daily driving, the following points should be noted: Do not delay transmission fluid changes for extended periods. Prolonged intervals between fluid changes can damage internal components such as bearings and the transmission housing. Avoid prolonged coasting in neutral. While many experienced drivers coast in neutral when driving manual transmission vehicles, doing so in an automatic transmission can cause overheating. Additionally, shifting back into Drive (D) from neutral can create a noticeable jolt. Never shift into Drive (D) or Reverse (R) before the vehicle has come to a complete stop. Some drivers attempt to demonstrate smooth operation by shifting into reverse while the vehicle is still moving, but this can severely damage the transmission gears and may lead to gear grinding over time. Do not frequently climb steep hills in Drive (D). Automatic transmission vehicles can overheat under high loads or may upshift prematurely, resulting in insufficient power for hill climbing. In such situations, using manual mode to maintain lower gears or switching to sport mode can help protect the transmission. Do not tow the vehicle over long distances. If an automatic transmission vehicle breaks down, it should be transported using a flatbed tow truck with the transmission in Neutral (N). Never use a tow rope or similar method to tow the vehicle directly.

How to restore ETC after removal?

After removing and reinstalling, it cannot function normally. During installation, there is a button on the back of the device that connects to the windshield. Data is only saved when this button is pressed. During secondary removal, the button pops out, triggering the reset mechanism and clearing all data, rendering it unusable. In this case, reinstallation is the only solution. ETC stands for Electronic-Toll-Collection, an electronic toll collection system. To apply, provide the vehicle owner's valid ID and vehicle registration certificate (original and copies). If applying through an agent, the agent's valid ID is also required. The copy of the vehicle registration must include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is needed. Applicants must be aged 18 to 60, and the vehicle must be under personal ownership. Documents required for company vehicles: An introduction letter from the vehicle owner (with official seal); Copy of the organization code certificate or business license (with official seal); Agent's original ID; Original vehicle registration certificate; The vehicle to be equipped with ETC. How ETC works: The vehicle-mounted electronic tag installed on the windshield communicates with the microwave antenna in the ETC lane at toll stations. Backend computer networks then settle payments with the bank, allowing vehicles to pass through highway or bridge toll stations without stopping to pay. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Reduces noise and exhaust emissions as vehicles pass through toll stations without stopping; Cost-efficient: Lowers wear and fuel consumption by reducing the frequency of vehicle starts and stops. Users also enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC systems more advanced and high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

Where is the automatic brake switch located in a Mercedes-Benz?

Mercedes-Benz's automatic brake switch is located in the vehicle's onboard computer system. There is an option to activate the active braking function within the onboard computer menu - simply select it to enable the system. The active braking system is a branch of automotive safety assistance systems, originally designed to reduce accident probabilities through proactive safety measures before collisions occur. When the system detects potential hazards, it initiates multiple preventive braking actions to avoid or mitigate collision risks. Mercedes-Benz is a German luxury automotive brand renowned for its perfect engineering, rigorous quality standards, continuous innovation capabilities, and a series of classic coupe models. The Mercedes three-pointed star is one of the world's most iconic automotive logos.
