Is ETC Card Skimming Real?

ETC cards inserted in vehicles can be skimmed, so it is recommended to remove the ETC card when parking to prevent unauthorized transactions. Precautions for ETC Usage: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, maintain a distance of over 10 meters to prevent automatic fee deduction for the preceding vehicle in case of ETC device malfunction or absence. The recognized speed for ETC lane passage is 20km/h. Excessive speed may result in failure to read vehicle device information and unsuccessful fee deduction. Unauthorized removal or movement of OBU devices, detachment or loosening of ETC electronic tags may render them ineffective. These can be taken to the issuing bank or highway service center for inspection. Non-deliberate loosening or detachment only requires reactivation. When using a debit card linked to ETC, insufficient balance may cause fee deduction failure. Follow on-site staff guidance to use manual MTC lanes with cash or card payment. Excessively thick windshields may cause poor signal reception. This is particularly noteworthy for vehicles with replaced windshields after accidents or modified front windshields.

How to Identify a Stock Car When Buying a Car?

Here are the methods to identify a stock car: 1. Check the production nameplate: Usually, there is a nameplate on the lower part of the B-pillar on the right side (passenger side) of the vehicle, which indicates the production date of the vehicle, engine parameters, and other information, making it easy to see. 2. Check the glass: The production date of the glass is marked on the car glass. The number represents the year, and the black dots represent the month. If the black dots are in front, subtract the number of black dots from 7; if the black dots are behind, subtract the number of black dots from 13 to get the month. 3. Check the tires: It may not be 100% certain whether the car is a stock car, but the production date of the tires can give a rough estimate of the production time. The four-digit number indicates the week (first two digits) and the year (last two digits). By observing the tires, you can preliminarily judge whether the car has been driven many miles since production. New car tires should be relatively clean, and the tire hairs should still be intact. 4. Check the engine compartment: Open the engine hood and see if it is clean. If it is particularly dirty or has a lot of dust, it indicates that the car has been parked in a harsh environment.

What is the fuel consumption of the Qashqai?

The fuel consumption of the Qashqai is 6.8-7.3L/100km. Additional Information: Methods to reduce fuel consumption are as follows: 1. Regular maintenance: Regular maintenance can reduce the failure rate of the car and also lower fuel consumption. Maintenance includes replacing parts such as spark plugs, oil filters, brake fluid, radiator coolant, air filters, power steering fluid, transmission fluid, etc. Keeping the vehicle in optimal condition helps reduce fuel consumption. 2. Avoid hard acceleration: Hard acceleration only shortens driving time by 4%, but increases fuel consumption by 37%-40%. On typical urban roads, the speed is usually maintained at 50 km/h, with engine RPM around 2000-2500. On highways, the speed is generally 90-110 km/h. For every 10 km/h increase in speed, fuel consumption increases by 10%. Avoid hard acceleration as RPM is the biggest factor affecting fuel consumption. 3. Reduce weight: For every 100KG increase in vehicle weight, fuel consumption increases by 4%-5%. 4. Maintain tire pressure within the normal range: Checking tire pressure not only benefits fuel consumption but also ensures driving safety. Develop a habit of checking tire pressure daily. Generally, the front tire pressure should be 2.2-2.3, and the rear tire pressure should be 2.4-2.5.

What kind of engine oil can be used for the Mazda 3 Axela?

The manufacturer recommends 0W-20 full synthetic or 5W-30 semi-synthetic engine oil for the Mazda 3 Axela. The oil filter models for the Mazda 3 Axela are: Mann: W67/1, Bosch: 0986AF0063, Mahle: OC980. Below are the precautions for using engine oil in the Mazda 3 Axela: 1. For new cars under normal driving conditions, if synthetic oil is used, the oil can generally be changed every 10,000 kilometers, and in some cases, it can even be extended to 20,000 kilometers. 2. "Normal driving" refers to frequent highway driving with minimal stop-and-go traffic. However, if you often drive in the city, encountering traffic lights everywhere and frequent traffic jams, with most trips not exceeding more than a dozen kilometers, this type of driving is considered "severe driving." Under "severe driving" conditions, engine wear is greater, and the requirements for engine oil are higher. Therefore, it is recommended to shorten the oil change interval to effectively protect the engine. 3. After prolonged use, engine oil accumulates a large amount of impurities. If the oil is not replaced in time, these impurities can wear down the engine and shorten the vehicle's lifespan.

They are used for illuminating the road and providing safety warnings during rainy or foggy weather, enhancing visibility for the driver and other traffic participants. In addition to the car's high beams, low beams, headlights, parking lights, driving lights, and brake lights, there is also a set of inconspicuous fog lights at the rear of the vehicle. Rear fog lights are designed to make the vehicle more visible to other road users behind it in environments with low visibility, such as fog, rain, or dust. 2. Jetta Body Dimensions: The Jetta's body dimensions are 4487mm in length, 1706mm in width, and 1470mm in height, with a wheelbase of 2603mm.

What is the service life of a Passat battery?

Whether it's a maintenance-free battery or a conventional battery, the normal service life is around 2-3 years. With careful maintenance, it can last 3 to 4 years, equivalent to a driving mileage of 60,000 to 90,000 kilometers. If the battery cannot be charged or the starter is weak, and the headlights are noticeably dimmer, the battery should be removed and charged for 12-24 hours with a charger. Below are precautions for using the battery: 1. When the car lights are dim and red, the horn sounds weak, and the starter operates sluggishly: Stop using the battery immediately and charge it right away. Try to increase charging opportunities during use and keep the battery fully charged. In winter, ensure the battery remains fully charged to prevent the electrolyte from freezing due to low density, which could damage the battery. 2. If the first start attempt fails, avoid repeatedly trying to start the engine: From the perspective of automotive working principles, continuous starting of the motor will definitely cause excessive battery discharge and damage. The interval between subsequent start attempts should be more than 5 seconds.
