How to resolve the flashing gear wrench indicator on Volkswagen CC?

Is driving at 126 km/h on the highway considered speeding?

It depends on the specific situation. It varies based on which class of highway you're on—some areas have a speed limit of 100 km/h, some 80 km/h, and others 120 km/h. More information on speeding is as follows: 1. Speeding: Refers to a driver operating a vehicle at a speed exceeding the legal or regulatory limits. 2. Speeding accidents: These are often caused by faults in the turbine's speed control and protection systems or inherent defects, but they are also directly related to operational, maintenance, and handling practices. The primary function of a turbine's speed control system is not only to ensure normal operation at the rated speed but also to prevent the speed from exceeding the permissible limit after load shedding. Therefore, the speed control system is the first line of defense against turbine overspeed.

What Lights Should Be Turned on in Rainy Weather?

Here is the relevant knowledge about what lights to use when driving in the rain: 1. Light rain: Use the width indicator lights during light rain. For example, when it starts to rain, the sky is relatively dark, but visibility is still good. In this case, the width indicator lights should be used. 2. Heavy rain: Turn on the headlights or front fog lights during heavy rain. When the rain is heavier, the rainwater itself can obstruct visibility, and the water on the road surface can be splashed up by the rolling tires of the vehicle in front, forming a mist that also significantly affects visibility. In such conditions, the headlights or front fog lights should be turned on. 3. Torrential rain: Turn on the rear fog lights during torrential rain. The red tail lights themselves have excellent penetration power, and generally, heavy rain cannot block their light. The rear fog lights are very bright and are designed to penetrate thick fog.

What is the Difference Between High-Revving and Low-Revving Engines?

High-revving and low-revving engines differ as follows: 1. High-revving engine: Refers to an engine where the maximum power and maximum torque peaks are achieved at relatively higher engine speeds. Generally, the maximum output power occurs above 5,000 RPM, and the maximum torque occurs above 3,500 RPM. High-revving engines typically have slightly larger cylinder bores. The reason for this is that their piston strokes are very short, which is necessary to achieve high RPMs. High-revving engines are not large in displacement, and part of their power comes from the inertial forces generated at high RPMs. 2. Low-revving engine: Generally has high torque, making it easier to start and providing strong towing power. The maximum torque usually appears around 3,000 RPM. Compared to passenger car engines of the same displacement, low-revving engines tend to have relatively lower power. Low-revving engines have slightly smaller cylinder bores, and their pistons are longer than those in high-revving engines. Because the piston stroke is long and the compression ratio is high, the pistons endure greater pressure and thus need to be sturdier. Their power often comes purely from the extremely high compression ratio. Since their RPMs are relatively low, the inertial forces generated during operation are quite limited.

Can zr17 and r17 tires be used interchangeably?

zr17 and r17 tires can be used interchangeably, as the only difference lies in the internal structure of the tires, which does not affect their functionality. When replacing tires, the following factors should be considered: 1. Local traffic regulations (ensuring they do not affect vehicle inspection, warranty, etc.); 2. The speed and load index of the tires; 3. The specifications of the rims; 4. Available space; 5. The vehicle's suspension system; 6. Maintaining the same load radius of the tires. Car tires are one of the essential components of a vehicle, directly in contact with the road surface. Together with the vehicle's suspension, they help absorb shocks during driving, ensuring a comfortable ride and smooth operation. They also ensure good adhesion between the wheels and the road surface, thereby improving the vehicle's traction, braking, and off-road capabilities.

How to Use Tesla's Summon Feature?

Tesla's summon feature can be used as follows: 1. Press the front button twice consecutively to open the vehicle's trunk and frunk; 2. Press the middle button twice consecutively to open the vehicle's doors, causing the door handles to pop out; 3. Press the rear button twice to open the vehicle's frunk. Taking the Tesla Model Y 2021 Long Range Dual Motor AWD version as an example: It is a 5-door, 5-seater SUV with dimensions of 4750mm in length, 1921mm in width, and 1624mm in height, a wheelbase of 2890mm, a dual-motor all-wheel-drive system, an electric all-wheel-drive configuration, and electric power steering.

How many liters of antifreeze does the Envision need?

The Envision requires 5 to 6 liters of antifreeze. Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance characteristics such as freeze protection in winter, boil-over prevention in summer, and year-round protection against scale and corrosion. How to replace antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipelines, with particular attention to the five-way water pipe. Antifreeze is distributed to different parts of the vehicle through the five-way pipe to perform its functions. If there are any signs of antifreeze leakage in this section, replace the water pipe or resecure the connection as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir and continue filling until water flows continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir will have a faint pink tint. Continue adding clean water until the outflowing water runs clear. Remember to disconnect the heater hose to drain all water from the heater core. Approximately one hour after draining, add the new antifreeze through the radiator hose. Then, pour another container of antifreeze into the antifreeze reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop slightly as air is purged from the system. Top up the antifreeze to the "MAX" mark on the reservoir.
