What is the Difference Between Tiptronic and Automatic Transmission?

Tiptronic has two modes: one is automatic mode, and the other is manual mode, while automatic transmission, as the name suggests, only has automatic mode. Here is some relevant information: 1. When climbing a long and steep slope, you can switch to manual mode and then shift to 1st gear. This will limit the vehicle to driving in a low gear, preventing frequent gear shifts, which makes the vehicle more powerful when climbing and also protects the transmission. 2. When descending a long slope, you should also use manual mode to keep the transmission in a low gear. This helps control the vehicle's speed without having to press the brake for a long time, avoiding overheating of the brakes and affecting braking performance. 3. When accelerating to overtake, if you want to overtake quickly, switch to manual mode and downshift first. The vehicle can then use the high torque of the lower gear to accelerate instantly, completing the overtaking maneuver faster. Downshifting here does not necessarily mean shifting to a low gear below 3rd gear every time before overtaking, but rather lowering one gear from the current gear while keeping the engine speed around 2500 rpm to obtain sufficient torque for acceleration.

Is it okay to change engine oil once a year?

If the vehicle owner drives relatively few kilometers in a year, they can choose to change the engine oil once a year; if they drive more kilometers in a year, it is recommended to change the oil twice a year to ensure the normal operation and internal cleanliness of the engine. Below are some precautions for changing car engine oil: 1. Topping up oil without changing it: Simply adding oil without changing it only brings the oil quantity to a standard level but does not fully restore the oil's performance. In other words, adding new oil to oil that has already been used for some time does not return the oil to its optimal performance. Just topping up oil without changing it is not sufficient. Some cars consume oil more quickly, and topping up can only serve as a short-term engine maintenance method. Once the oil reaches the end of its lifecycle, it must be completely replaced with fresh oil. 2. Do not mix two different brands of engine oil: Engine oils in cars are essentially base oils with different additives. The base oils are the same, but the types and quantities of additives vary, resulting in different oil varieties and grades. If different oils are mixed, these additives may undergo chemical reactions, damaging the original performance of the oil. Therefore, mixing different oils is not recommended.

Can a repaired tire still be used on highways?

If there is no air leakage after the repair, it can be driven normally on highways, but regular checks should be conducted. Below is relevant information: 1. The general judgment standard is 6 millimeters, which is approximately the width of a little fingernail. When the damage does not exceed this width, some repaired tires can be used on highways. If the damaged area of the tire exceeds 6 millimeters, regardless of the repair method used, it is not recommended to drive on highways. 2. The sidewall of the tire cannot be repaired. A puncture on the tread with a diameter exceeding 6 millimeters cannot be repaired. If there is damage or deformation to the bead, tread deformation, rubber corroded by chemicals, or damage caused by driving under-inflated, the tire cannot be repaired. Other abnormal conditions also cannot be repaired.

What does the exclamation mark on the car mean?

The appearance of an exclamation mark on the car's dashboard indicates an abnormality or malfunction in the corresponding system. There are many indicator lights on the car dashboard that feature an exclamation mark, such as the tire pressure indicator light, lighting fault indicator light, steering system fault indicator light, brake system fault light, transmission fault indicator light, and wiper fault indicator light. Below is a detailed introduction to the exclamation mark warning lights: General Faults: An exclamation mark inside a triangle: If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor faults, fuel cut-off system intervention or faults, external light faults, engine oil pressure sensor faults, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside: This is the automatic transmission fault warning light, indicating a fault in the transmission or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circle with parentheses: This represents a warning for the brake system, mainly indicating a fault in the brake system or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Abnormal Tire Pressure: An exclamation mark below a horizontal line with parentheses: This represents the tire pressure monitoring warning light. When the car's tire pressure is too low, this warning light will illuminate. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark: This is the lighting fault indicator light, indicating a fault in one of the car lights. Solution: Visit a 4S shop as soon as possible for inspection and repair, or check yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights, to identify the problem. In addition, during daily use of the vehicle, the warning lights displayed on the dashboard are divided into two colors: yellow and red: Yellow indicates a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the nearest repair point to eliminate potential safety hazards. Red indicates a very serious problem in the corresponding system. In such cases, do not continue driving. Pull over immediately and seek professional assistance to prevent unforeseen dangers to the vehicle and personal safety. It is important to note that when the car is started, all lights will illuminate as the system performs an automatic check. After the check is completed, the lights will turn off automatically. If a light does not illuminate when the ignition is turned on, remains lit, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly for inspection and repair to eliminate safety hazards.

Rearview mirror assembly refers to all the parts related to the rearview mirror, including: the housing, mirror surface, rotating motor, heating coil, adjustment bearing, wiring, and angle adjustment lever. The term "assembly" means the overall combination. Modern vehicles are highly modular, and a vehicle is often composed of multiple assemblies. Below are the specific details: 1. Modern vehicles have long adopted modular design, the advantage of which is that upgrades and repairs are more convenient. When a vehicle needs an upgrade or repair, the corresponding assembly can be directly replaced. The rearview mirror is extremely important for driving, so car owners need to regularly maintain and service the rearview mirror; otherwise, driving can be very dangerous. 2. The rearview mirror assembly consists of the following components: (1) The rearview mirror housing and mirror surface, which are the main structures of the rearview mirror. (2) The rearview mirror rotating motor is the main component that controls the rotation of the rearview mirror, with the angle adjustment lever operated by the car owner. (3) The servo motor, which automatically unfolds the rearview mirror when the vehicle is unlocked and automatically folds it when the vehicle is locked.
