What are the precautions for using ETC?

Precautions for using ETC include: The ETC transaction sensing range is 8 meters. When encountering a vehicle in front that has stopped, to prevent the front vehicle's ETC device from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the front vehicle to avoid automatic sensing and paying for the front vehicle. The ETC lane recognizes a vehicle speed of 20km/h. If the speed is too fast, the vehicle device information cannot be read, which will also result in a failed fee deduction. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will cause the electronic tag to become invalid. It can be sent to the bank where the ETC card was issued or the highway service office for testing. If the detachment or loosening is not man-made, it only needs to be reactivated. When using a debit card to bind with ETC, insufficient balance will also result in a failed fee deduction. You can follow the guidance of on-site staff to use the manual MTC lane and pass by using cash or card payment. A windshield that is too thick may cause poor sensing. This is especially important for vehicles that have had their windshields replaced after an accident or for those who have modified their front windshields.

What are the gears of the Santana?

Santana has 6 gears, including 5 forward gears and 1 reverse gear. The following is an introduction to manual transmission cars: Composition of manual transmission cars: By switching different gear sets, gear shifting is achieved. As a key component in distributing power, the transmission must have two major parts: the power input shaft and the output shaft, along with the gears that make up the transmission, forming the most basic components of a manual transmission. Working principle of manual transmission cars: The power input shaft is connected to the clutch, and the power transmitted from the clutch is directly passed to the gear set through the input shaft. The gear set consists of gears with different diameters, and different gear ratios result in completely different power transmission effects. The gear shifting during normal driving refers to changing the gear ratio.

How Many Days Until You Know You Ran a Red Light?

After running a red light, the illegal photo notification SMS is usually received within 3 to 7 days, with the latest being around 13 days. However, some cities now offer "electronic police instant capture alerts," where you can receive an SMS notification within 5-10 minutes of being captured. But a notification does not equate to a violation; it serves only as a capture alert. The final determination of whether it is a violation still takes 3-7 days. If it is indeed a violation, you will receive another SMS notification. For traffic violations captured by surveillance cameras, vehicle owners generally do not receive the violation SMS immediately. There is a delay, and the duration may vary. This is because after an electronic camera captures a violation, the relevant violation information needs to be transmitted through a dedicated channel to the traffic police management center, where it is compiled before being forwarded to the relevant traffic police personnel for verification. Once confirmed as a violation, the system automatically retrieves the corresponding vehicle owner's mobile phone number based on the license plate information. Only then is the violation sent to the owner via SMS, and the owner receives the corresponding violation notification. After receiving the violation SMS, the vehicle owner must go to the traffic police department where the violation occurred to handle the matter within one month before the vehicle's annual inspection. Generally, if a vehicle owner suspects they have committed a violation, they can use 15 days as a benchmark. If no violation SMS is received beyond 15 days, it is likely that no violation was recorded. Traffic Violation Query Methods: Traffic violation queries refer to checking motor vehicle violations of traffic management through online or terminal methods. Methods for querying vehicle violations include vehicle violation websites, phone queries, SMS queries, mobile app queries, and offline terminal queries. Website Query: You can search for "vehicle violation query" and input your vehicle information to check. Phone Query: To query violations, you can call the local 114 (area code + 114) or 12580 for confirmation. Violations can only be handled at the traffic police department where the violation occurred or where the vehicle's license plate was issued. For on-the-spot violations, such as those directly caught by a traffic officer, they must be handled at the violation location. SMS Query: Open your phone's SMS interface; enter "WZ" followed by your license plate number and color in the message body; input 1062650001 as the recipient and click send. Mobile App Query: Open the Traffic Management 12123 app, log in, and click on "Vehicle Violations" to enter the query interface, which displays recent unprocessed violation records. Offline Terminal Query: Visit the local traffic management hall and use the self-service query machine to input your license plate number to check recent violation records.

What is the Difference Between Brake Fluid and Brake Oil?

There is no difference between brake fluid and brake oil; brake fluid is the formal term, while brake oil is the colloquial name. Brake oil is a functional liquid used to stop the rotation of the wheels, serving to transmit energy and providing anti-corrosion, anti-rust, and lubrication effects. Types of brake oil: castor oil-alcohol type, made from refined castor oil and low-carbon alcohol; synthetic type, made with ethers, alcohols, esters, and additives for lubrication, oxidation resistance, rust prevention, and rubber swelling resistance; mineral oil type, made from refined light diesel oil fractions with thickeners. Precautions for using automotive brake oil: If gasoline, diesel, or engine oil is accidentally mixed into a synthetic brake oil system, the incompatibility between the fluids can reduce braking effectiveness. For vehicles driven normally for 40,000 kilometers or with brake oil used continuously for over two years, the brake oil may deteriorate due to prolonged use, so timely replacement is essential. Vehicles equipped with a brake oil level warning device should monitor whether the warning light flashes and ensure the sensor functions properly. When brake oil is low, it should be replenished promptly, and stored brake oil should be kept between the marked minimum and maximum capacity levels. If braking becomes inconsistent during normal driving, the brake oil should be replaced immediately. Before replacement, clean the braking system with alcohol. If the vehicle pulls to one side during braking, conduct a comprehensive inspection of the braking system. If the wheel cylinder rubber cup is excessively swollen, it may indicate poor brake oil quality. In this case, replace it with higher-quality brake oil and also replace the rubber cup. During seasonal changes, especially in winter, if braking effectiveness declines, the brake oil grade may not be suitable for winter conditions. When replacing, choose brake oil with lower viscosity in cold temperatures. Do not mix different types or brands of brake oil. For braking systems with special requirements, use the specified brand of brake oil. Different brands and types of brake oil have varying formulations, and mixing them can degrade performance. Even if brands claim compatibility or substitutability, long-term mixed use is not recommended. If water or impurities are found in the brake oil, replace or thoroughly filter it to prevent insufficient braking pressure and compromised braking performance. Regularly replace brake oil: Brake fluid volume changes with temperature, so the brake oil reservoir has a vent. Air drawn in through this vent may contain moisture or impurities, which can lower the boiling point of the brake fluid. During prolonged braking, the system heats up, potentially causing vapor lock, compressed air, and reduced braking effectiveness or failure. For safety, brake oil must be replaced periodically.

Differences Between the Wrangler Rubicon and Sahara?

Here are the specific differences between the Sahara and Rubicon: Ground clearance: The Sahara has a ground clearance of only 254mm, while the Rubicon reaches 274mm. Four-wheel drive system: Compared to the Rubicon, the Sahara adds a 4H Auto mode. This four-wheel drive mode is closer to the on-demand four-wheel drive system of urban SUVs, using a multi-plate clutch to control whether the four-wheel drive is engaged or disengaged. Front and rear axles: The Rubicon uses thicker Dana front and rear axles compared to the Sahara, and only the Rubicon offers front and rear differential locks.

What is the Difference Between Gear Oil and Engine Oil?

Automotive gear oil and engine oil differ in their working environments and primary focuses. Here is a related introduction to the differences between gear oil and engine oil: 1. Different working environments: Gear oil is mainly used in manual transmissions, reducers, and differentials, while engine oil is primarily used in automobile engines. Since gear meshing involves direct contact, gear oil must have extremely high viscosity to form an oil film at the gear meshing points. In contrast, engine lubrication involves mostly surface contact without the extreme high pressure generated by gear meshing, so the viscosity requirements are relatively lower. 2. Different focuses: Gear oil emphasizes protecting gears under high temperatures, while engine oil focuses on its fluidity at low temperatures. Additionally, gear oil is strongly alkaline, whereas engine oil is weakly alkaline.
