What to Do If You Hit a Parked Car on the Roadside?

Should the Audi Q3 use 92 or 95 octane gasoline?

According to the official vehicle manual recommendation, the Audi Q3 should use 95 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, you can also find it on the fuel tank cap, which will be clearly marked. Generally, 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 new technologies, the compression ratio alone cannot determine the gasoline grade. High compression ratio engines can also be tuned to use lower octane 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 octane number, the higher the octane value 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 Audi Q3 occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use low-octane gasoline, using high-octane gasoline by mistake will not cause damage, but the increase in octane value will alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use high-octane gasoline, using low-octane gasoline can cause engine knocking. Since the octane value is much lower, the reduced ignition point may cause premature ignition during the compression stroke. If combustion occurs before the spark plug ignites, resistance will arise during the upward stroke. This resistance makes the engine run very unstable. If the knocking is imperceptible, it only increases noise without significant damage to the engine. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

How to Use the Foot-Operated Parking Brake?

Usage method: Press the pedal all the way down with your left foot to engage the brake; press it again firmly with your left foot and then release to disengage the parking brake. Below is relevant information about parking brake types: 1. Definition: Parking brake types refer to the operation methods of parking brakes. 2. Classification: Currently, passenger vehicles have three types of parking brake operations: handbrake, footbrake, and electronic parking brake. Foot-operated parking brakes, as the name suggests, are controlled by the foot and are commonly found in automatic transmission models. Traditional 'handbrakes' are manually operated with a force requirement of less than 200N (equivalent to 20 kgf). However, for many women with limited strength, this operation can be unfriendly, often resulting in insufficient parking brake force due to inadequate pressure, leading to vehicle rollback. The foot-operated parking brake effectively solves this issue.

What does the yellow TC light in a car mean?

The yellow TC light with a slash on a car's dashboard represents the Traction Control System, also known as the Traction Control System. Normally, this indicator light appears when the car is first started, as the system automatically checks the status of the traction control system. Once the check is completed successfully, the light will turn off. If the light remains on, it could mean that the traction control system has been manually turned off. In this case, you need to locate the system's control switch (usually found near the gear shift lever) and turn it back on. If the traction control system was not accidentally turned off, there might be a fault in the system. It is important to promptly identify the issue and its cause. If a fault is confirmed, the car should be taken to a professional repair shop for servicing. A malfunctioning traction control system can prevent the car from achieving optimal traction, leading to difficulties in smooth starting and accelerating on slippery surfaces. In severe cases, the drive wheels may spin without moving the car forward.

What Does the Wrench on the Dashboard Mean?

The wrench indicator light on the car dashboard means: the car has reached the maintenance period and should be taken to a 4S shop for servicing. After maintenance, the indicator will disappear. Maintenance Reminder Introduction: The maintenance cycle of the car is set when the vehicle leaves the factory, so the "small wrench" will appear every certain mileage to remind the driver to perform maintenance in time. Usually, the car maintenance cycle is every 5,000 to 8,000 kilometers, while the factory-set cycle is generally longer than 8,000 kilometers. Car Maintenance Introduction: Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Modern car maintenance mainly includes the maintenance scope of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc.

What are the changes in the BMW 5 Series facelift?

The BMW family-style front fascia has been updated in this facelift with a sport package design, making it more youthful, and the entire headlight assembly has also been upgraded. The vehicle's overall length exceeds 5 meters, with specific dimensions of 5087*1868*1500 mm and a wheelbase of 3108 mm. These dimensions surpass those of its competitors in the same class, giving it a significant advantage. Additional Information: 1. The BMW 5 Series is one of the most outstanding series in automotive history. As a mid-size sedan, the BMW 5 Series features a stylish appearance and is highly favored by young achievers, securing a prominent position in the domestic mid-to-high-end car market. 2. BMW's 2019 product launch plan did not include a mid-cycle facelift for the 5 Series. Based on the 7 Series timeline, the 7 Series was redesigned in 2016, with its mid-cycle facelift in 2019. The 5 Series redesign followed a year later than the 7 Series, so its mid-cycle facelift is also expected to be delayed by about a year. Therefore, the BMW 5 Series mid-cycle facelift is anticipated to arrive in 2020.
