Will the 4S store replace a new car tire for free if it's damaged?

During the warranty period, if the tire is damaged under normal usage conditions as specified, it can be replaced for free. Within the car's warranty period, any malfunction or part damage that occurs under normal usage conditions as specified will be repaired or replaced by the manufacturer at no cost to the owner. However, the following situations will void the free warranty service: Failure to perform maintenance as required: If the owner does not take the new car to the designated 4S store or manufacturer-authorized service station for regular maintenance within the specified mileage, any issues that arise, even during the warranty period, will require the owner to pay for the repairs. Unauthorized modifications to the vehicle: "No warranty for modified cars" is a common policy among almost all manufacturers regarding warranty issues. Some brands even stipulate in their warranty terms that if the owner changes the vehicle's purpose without authorization, such as using it for rental, leasing, or competitive racing, it will be considered as voluntarily forfeiting the warranty rights.

Is the Electronic Driver's License from Traffic Management 12123 Nationally Valid?

Starting from September 1st, 28 cities will begin to promote and implement the electronic version of the driver's license. For drivers in these 28 pilot cities, they no longer need to carry a physical driver's license when driving. However, for cities not included in this promotion, electronic driver's licenses are still supported. Therefore, it is nationally valid, but in some areas, it is still advisable to carry and use the electronic driver's license. Pilot Cities: These 28 cities include: Beijing, Tianjin, Shijiazhuang, Changchun, Daqing, Shanghai, Wuxi, Suzhou, Yancheng, Taizhou, Ningbo, Jiaxing, Nanchang, Jinan, Qingdao, Changsha, Guangzhou, Shenzhen, Nanning, Chongqing, Chengdu, Mianyang, Zigong, Nanchong, Guiyang, Kunming, Xi'an, Yinchuan. Composition of Electronic Driver's License: The electronic driver's license consists of two parts: the main page and the supplementary page. The main page mainly includes basic information of the driver's license, the generation time of the electronic certificate, QR codes and barcodes for verification, etc. The supplementary page mainly includes the driver's residential address, issuing authority, driving records, and the code regulations for permitted vehicle types.

Where are the engine sensors located?

Locations of various engine sensors: The crankshaft position sensor is located near the flywheel, and the camshaft position sensor is positioned close to the camshaft. Crankshaft Position Sensor: It is the most critical sensor in the computer-controlled ignition system. Its function is to detect top dead center signals, engine speed signals, and crankshaft angle signals, then input them into the computer to control the cylinder ignition sequence and issue optimal ignition timing commands. Camshaft Position Sensor: It collects the valve camshaft position signals and inputs them to the ECU, enabling the ECU to identify the top dead center of the first cylinder's compression stroke (providing cylinder identification signals). These signals serve as the sole basis for the ECU to perform fuel injection timing and sequential control, thereby managing sequential fuel injection, ignition timing control, and knock control. Additionally, it is used to identify the initial ignition timing.

Does the auto headlight consume battery when parked?

Auto headlights will consume the battery power after the engine is turned off, but the power consumption is not significant. When the car is turned off, the generator stops working, and the only power source for the entire vehicle is the battery. If the headlights are left on for a long time without being turned off, it can easily lead to battery depletion, affecting engine startup and shortening the battery's lifespan. If the lights do not remain on after power-off, there will be no power consumption. Therefore, it is recommended to turn off the auto headlights after the engine is turned off to develop a good habit. How to turn off auto headlights: Auto headlights can be turned off immediately by quickly pressing the lock button twice. Some cars have an auto headlight function that will turn off after a while, while others will sound an alarm if the lights are not turned off, reminding the user to switch them off. There is also a 'go home' feature where the headlights stay on for a few dozen seconds before automatically turning off. How auto headlights are activated: Auto headlights are a light-sensing control system installed by some car manufacturers for user convenience. When the light dims while driving, the headlights will automatically turn on, and they will turn off when the light brightens. It's worth noting that many people mistakenly believe that 'auto headlights' are designed specifically for driving through tunnels, but this is not the case. Auto headlights have a delay in activation; the headlights will only turn on within a dozen seconds after the light-sensing system detects dimming light. According to traffic regulations, headlights must be turned on before entering a tunnel, so when passing through a tunnel, it is still necessary to manually turn on the headlights in advance.

Can You Drive with Engine Oil at the Lower Limit?

Engine oil at the lower limit is still drivable. When the oil level reaches the lower mark on the dipstick, it only indicates that the engine oil quantity has reached the minimum allowable level, not that there is no oil left. Typically, there is about one liter of capacity between the upper and lower marks on the dipstick. Even at the lower limit, the lubrication function of the oil remains sufficient, but it is advisable to add oil as soon as possible. The functions of engine oil are as follows: Lubrication: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear. Auxiliary Cooling: Engine oil has a relatively low specific heat capacity and, being inside the engine, does not inherently have a cooling effect. However, during engine operation, heat is generated by fuel combustion. The oil can carry this heat back to the oil pan, where it is dissipated into the air, assisting the radiator in cooling the engine. The actual cooling is performed by the water outside the engine casing.

Is it okay to run the AC without driving?

Running the AC without driving is acceptable for short periods, but it is not recommended for extended durations. Below are the impacts of running the AC without driving and the working principle of the automotive AC automatic control system: Impacts of running the AC without driving: Running the AC for a long time without driving can lead to increased carbon deposits in the engine. Carbon deposits are quite harmful to the engine. When the engine is idling, the combustible mixture in the cylinders cannot burn completely, resulting in an accumulation of carbon deposits in the engine. Principle of the automotive AC automatic control system: Based on signals from various sensors detecting cabin temperature, evaporator temperature, engine coolant temperature, and other relevant switch signals, the system outputs control signals to regulate the operation of the radiator fan, condenser fan, compressor clutch, blower motor, and air control motor, thereby achieving automatic control of the cabin temperature.
