Why Do Small Cars Need to Add Water?

Reasons why small cars need to add water: To dissipate heat generated by the engine: Engines are divided into two types of cooling systems: air-cooled and water-cooled. Air-cooled engines dissipate heat by increasing airflow to cool the engine, while water-cooled engines, which are more common, use the circulation of water in the cooling system to remove heat generated by the engine, ensuring the engine operates at its optimal state. To cool down components: During operation, engines generate high temperatures. If components are not cooled down in time, the engine can eventually be damaged. Therefore, cooling measures are essential, whether through water-cooling or air-cooling. Water-cooling is commonly used in various engines, hence the need to add water, while air-cooling is typically found in motorcycle engines and military engines.

What is the wading depth of the Volkswagen T-Roc?

The maximum wading depth of the Volkswagen T-Roc is 500mm. The wading depth of the Volkswagen T-Roc is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Therefore, in terms of safe wading depth, the advantages of off-road vehicles and SUV models are obvious. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when passing through waterlogged roads. If the air intake of the Volkswagen T-Roc is below the water level when wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. The height of the engine's air intake, and thus the maximum wading depth, can also be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before the vehicle enters the water, always turn off the auto start-stop function to prevent the engine from automatically restarting after stalling in the water, which could cause severe damage due to water ingress. Assess the underwater road conditions based on the passage of vehicles ahead and choose an appropriate entry point. Observe the path taken by other vehicles and follow their tracks at a low speed, avoiding sudden acceleration or deceleration. For roads prone to water accumulation, observe warning water level markers, trees, and reference points such as the wheels and doors of other vehicles to estimate the water depth before deciding whether to proceed. Be aware of your vehicle's safe wading depth. If the water depth exceeds half the height of the tires or the engine's air intake, do not enter the water recklessly; consider taking an alternative route instead.

Can ETC still be used when changing license plates but not the vehicle?

ETC cannot be used if the vehicle information it is bound to is inconsistent. Different vehicle types have different highway toll fees. According to the "Rules for the Use of Non-stop Rapid Passage Systems," when applying for ETC, the ETC card and OBU device are already bound to the vehicle, and the relevant vehicle information has been imported, forming a one-to-one correspondence. If you change to a new vehicle with new license plates, you need to cancel the original ETC and reapply for the new vehicle. If it's a new vehicle with old license plates, you can simply update the vehicle information at an offline service center. ETC is an electronic toll collection system that allows vehicles to pass through without stopping. ETC lanes are designated for vehicles equipped with ETC onboard units, using electronic toll collection. The electronic toll collection system is an automated toll system for highways or bridges. ETC deduction principles: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, the system uses computer networking technology to perform backend settlement with the bank, achieving the goal of vehicles not needing to stop at toll stations to pay highway or bridge fees. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs by reducing the frequency of vehicle starts and brakes, lowering wear and fuel consumption; Improved efficiency: Theoretically, ETC lanes can increase vehicle passing efficiency by 2-3 times, making traditional ETC faster, newer, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation smart cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a clear target in the main indicators for the development of comprehensive transportation during the 13th Five-Year Plan: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and increasing the ETC adoption rate for passenger vehicles, efforts will also be made to promote ETC usage for trucks in the future. There will be exploration of deep integration between the ETC system and smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC usage. ETC usage precautions: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, to prevent issues such as the vehicle's ETC device malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatic sensing and paying for the wrong vehicle. The recognized speed for ETC lane passage is 20 km/h. If the vehicle speed is too fast, the system may fail to read the vehicle's device information, resulting in failed fee deductions. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, can cause the electronic tag to malfunction. In such cases, you can take it to the bank where the ETC card was issued or the highway service center for inspection. If the detachment or loosening was not due to human error, reactivation may be sufficient. When using a debit card bound to ETC, insufficient balance can also lead to failed fee deductions. In such cases, follow the guidance of on-site staff to use the manual MTC lane and pay with cash or card. If the vehicle's windshield is too thick, it may cause poor sensing. This is particularly important for vehicles that have had their windshields replaced after accidents or for those who have modified their front windshields.

What Causes Battery Drain in a New Car After One and a Half Years?

New car battery drain after one and a half years can be caused by the following reasons: Reasons for leakage: If the car battery frequently drains, it indicates that there is an automatic discharge point after the car is parked. In a normal car, after the engine is turned off and the key is removed, only a few parts have power supply, and the power consumption is minimal. You can use the current range of a multimeter to check the output current of the battery. If it exceeds 15 milliamperes, it means there is a leakage point in the electrical system. Battery-related reasons: Reaching the end of its service life, insufficient electrolyte or leakage, and corrosion of battery terminals can all cause the battery to drain. Once bulging appears on both sides of the battery, it indicates that the car battery is not far from needing replacement.

Introduction to the function keys of the Bora car is as follows: Electronic Stability Program (ESP): Effectively prevents loss of control such as skidding or fishtailing. It is generally not recommended for drivers to manually turn it off. Hazard Warning Lights (commonly known as hazard lights): Used in special situations such as car breakdown or temporary parking, mainly to warn other vehicles. Parking Radar/Image: The central control screen displays the reversing image, and the radar will sound an alarm when detecting obstacles nearby. Driving Assistance System: Includes functions such as pre-collision protection, distance warning, and fatigue reminder. Auto Hold: When waiting at a red light, it relieves foot fatigue by automatically locking the wheels with the brake calipers. Pressing the accelerator again will allow the car to continue moving forward. Auto Start-Stop: During brief stops, the engine will shut off. When the driver's foot leaves the brake pedal, the vehicle will restart.
