What does 'No offline data for the starting city' mean?

No offline data for the starting city means the navigation data needs to be updated, as there is no data for your current location. Methods to update starting point data: If the vehicle's infotainment system has internet connectivity, you can directly update the system through the in-car navigation interface to upgrade the vehicle's navigation system. Alternatively, you can remove the navigation SD card, download the update data from the official navigation system website, and perform the update. Functions of starting point data: It not only allows you to view offline maps but also enables offline location searches, route queries, and navigation without consuming any mobile data. Simply download the map in advance. It's an essential tool for travel. Mobile navigation apps can also download offline data packages.

Is it acceptable for a novice to drive at 80 km/h in the rightmost lane on the highway?

Novice drivers on highways must maintain a minimum speed of no less than 80 km/h. Highway speed limits: Highways should indicate the speed limits for each lane, with the maximum speed not exceeding 120 km/h and the minimum speed not less than 60 km/h. On highways, the speed of small passenger vehicles should not exceed 120 km/h, other motor vehicles should not exceed 100 km/h, and motorcycles should not exceed 80 km/h. Precautions for novice drivers on highways: Due to their lack of driving experience, novice drivers often think that in any situation, simply stepping on the brakes to stop the car is sufficient. However, encountering emergencies on the highway can easily lead to accidents due to improper handling. For example, in the event of a tire blowout on the highway, many novice drivers tend to sharply turn the steering wheel and apply sudden brakes, unaware that this can easily cause the vehicle to lose control and overturn.

Must the vehicle owner apply for ETC?

Non-owners can also apply for ETC. According to the "Implementation Plan for Accelerating the Application Service of Electronic Non-stop Toll Collection on Highways" issued by the Ministry of Transport, the original valid ID card of the vehicle owner, the original and copy of the vehicle registration certificate, and the page of the registration certificate with the most recent annual inspection stamp are required. If applying on behalf of others, the original valid ID card of the agent is also required. If applying for ETC through major bank branches, a debit card or credit card from the corresponding bank must be prepared. Some banks only support ETC binding with credit cards, while others may require freezing a portion of the amount as a deposit when binding ETC with a debit card. The principle of ETC deduction: There will be one or more ETC lanes on the highway. Through the dedicated short-range microwave communication between the vehicle-mounted electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane of the toll station, the computer network technology is used to settle accounts with the bank in the background, achieving the purpose of paying road and bridge tolls without stopping at the toll station. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Save time: Eliminates the hassle of waiting in line; Green and environmentally friendly: Low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Save on wear and tear: Reduces costs, decreases the frequency of vehicle starts and brakes, lowers wear and fuel consumption, and users can enjoy a 5% discount on tolls; Improve efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also set a target in the main indicators of the "13th Five-Year Plan" for comprehensive transportation development: "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 the ETC usage rate for passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with the development direction of smart transportation, such as vehicle-to-vehicle communication and vehicle-to-road coordination, to provide comprehensive travel services for vehicle owners. This means that more application scenarios will support ETC applications. Precautions for using ETC: The ETC transaction sensing area is 8 meters. When encountering a stopped vehicle ahead, to prevent the ETC device of the vehicle ahead from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatically sensing and paying for the vehicle ahead. The recognition speed for ETC lane passage is 20 km/h. If the speed is too fast, the vehicle device information cannot be read, which will also result in a failed deduction. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will cause the electronic tag to fail. It can be sent to the bank where the ETC card was issued or the highway service office for testing. If the loosening or detachment is not man-made, it only needs to be reactivated. When using a debit card bound to ETC, insufficient balance will also result in a failed deduction. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card. Excessive thickness of the car windshield may cause poor sensing. This is especially important for vehicles that have been repaired after an accident and had their windshields replaced, or for those who have modified their front windshields.

What engine is equipped in the Changan CS85?

Changan CS85 is equipped with two types of engines, model numbers JL486ZQ4 and JL476ZQCF. The JL486ZQ4 engine has a maximum horsepower of 233, a maximum power of 171kw, a maximum power speed of 5500rpm, and a peak torque of 360N.m. The JL476ZQCF engine has a maximum horsepower of 178, a maximum power of 131kw, a maximum power speed of 5500rpm, and a peak torque of 265N.m. Changan CS85 uses the Blue Whale engine independently developed by Changan Automobile. In terms of actual driving performance, this engine performs very well. For daily maintenance of the Changan CS85 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB_CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid faults, change the oil regularly based on usage conditions and keep the oil volume moderate. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and bring contaminants back to the lubrication parts, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. A small amount of sludge remains suspended in the oil, while a large amount precipitates, clogging the filter and oil holes, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.

How to Adjust the Hot Air in the Car Air Conditioning?

After starting the vehicle, turn off the AC button of the air conditioning. When the water temperature rises to the normal value, turn on the warm air of the air conditioning. How to use the car air conditioning: First, start the vehicle and let it warm up. Wait until the water temperature reaches around 70, then turn on the warm air of the air conditioning. Next, press the air recirculation button, and it will light up. Rotate the knob in the temperature control area of the air conditioning to the red zone. If there is a digital display, increase the temperature. There is no need to turn on the AC, as the heat generated by the engine will provide warm air through the car's recirculation function. Precautions for using warm air in winter: Do not turn on the warm air immediately after starting the car. If the engine is not warmed up, turning on the warm air will not only be ineffective but also consume a lot of electricity. First, start the engine and let it warm up. After the engine temperature rises, then turn on the warm air. Initially, set the air to external circulation to expel all the cold air inside the car. Then, switch to internal circulation for more effective heating.
