What do the red and yellow dots on tires mean?

The red dot indicates the position with the maximum longitudinal vibration of the tire, which is the heaviest part and represents the tire's center of gravity; the yellow dot indicates the position with the minimum longitudinal vibration of the tire, which is the lightest part and represents the tire's light point. The following is an introduction to the functions of tires: 1. Supporting the entire weight of the vehicle: bearing the load of the car and transmitting forces and moments in other directions. 2. Transmitting traction and braking torque: ensuring good adhesion between the wheels and the road surface to improve the car's power, braking, and passability. Working together with the car suspension to mitigate the impact during driving and dampen the resulting vibrations. 3. Preventing severe vibrations and early damage to car components: adapting to the vehicle's high-speed performance and reducing driving noise, ensuring safety, handling stability, comfort, and energy efficiency.

How often should the transmission fluid in a Mistra be changed?

The transmission fluid in a Mistra is generally recommended to be changed every two years or 60,000 kilometers. Below is relevant information about transmission fluid: 1. An automatic transmission uses planetary gear mechanisms to shift gears. It can automatically shift based on the degree of throttle pedal input and changes in vehicle speed, while the driver only needs to control the speed using the accelerator pedal. 2. The most common type is the hydraulic automatic transmission. A hydraulic automatic transmission mainly consists of a hydraulically controlled gear-shifting system, comprising primarily an automatic clutch and an automatic transmission. It can automatically shift gears based on throttle opening and changes in vehicle speed. 3. Generally, the commonly used automatic transmissions in vehicles include the following types: hydraulic automatic transmission, hydrostatic automatic transmission, electric automatic transmission, stepped mechanical automatic transmission, and continuously variable mechanical automatic transmission.

Can I Pick Up the Car on the Same Day of Purchase?

Whether you can pick up the car on the same day of purchase depends on whether the 4S store has the car in stock. Here are some suggestions for car selection: 1. Power performance: The power performance of the entire vehicle depends on two aspects. One is the configuration of components, which is hardware, such as the engine, clutch, transmission, drive shaft, tires, etc. Among them, the engine is the core, the transmission is the hub, the drive shaft is the bridge, and the tires are the executors. The other is the matching of components, which is software. 2. Comfort: Mainly determined by the interior, seats, suspension system, etc. Among them, the interior and seats are directly related to personal taste, so we won't elaborate here. As for the suspension system, it can be divided into two categories: independent suspension and non-independent suspension. Non-independent suspension is mainly used in large buses or freight vehicles, with average shock absorption effect. Independent suspension is much more comfortable than non-independent suspension.

Can Halogen Lights Be Replaced with LED?

Halogen lights can be replaced with LED bulbs. However, it should be noted that the focal points of the reflector bowl and lens of the original halogen lights are different from those of LED lights. LED lights may produce uneven light beams, and depending on the quality of the product, if the heat dissipation and constant current effects are poor, the lighting effect will also be relatively poor. Poor heat dissipation of the lights can also have a significant impact on the vehicle itself. The replacement method is as follows: 1. First, purchase the corresponding LED bulb based on the model of the halogen light; 2. Remove the halogen bulb and plug in the LED bulb, securing it firmly with a ballast. However, replacing with an LED bulb may not always yield satisfactory results. Since the original vehicle light path is designed for halogen lights, with different focal points for the reflector bowl and lens, some vehicles may experience uneven lighting or the formation of light beams after installing these LED lights. Additionally, due to varying product quality, if heat dissipation and constant current are not properly managed, LED light decay can be very noticeable, significantly shortening the lifespan.

What transmission is used in the Senova X25?

The transmission brand used in the Senova X25 is Aisin. Established in 1969, Aisin is a world-renowned professional developer and manufacturer of automotive automatic transmissions, holding the world's highest market share in the automotive automatic transmission sector. The Senova X25 manual transmission uses a 5-speed manual gearbox, while the automatic transmission employs a 4-speed automatic. Automatic transmission: During driving, the transmission automatically adjusts to the most appropriate gear ratio based on throttle position and vehicle speed. For the Senova X25's transmission in daily use, pay attention to the following points: Do not delay transmission fluid changes for extended periods. Prolonged failure to change transmission fluid can damage internal components such as bearings and housings; Avoid prolonged coasting in neutral. Many experienced drivers coast in neutral when driving manual transmission vehicles, but for automatic transmissions, this can cause overheating and create shock when shifting back to D gear; Never shift into D/R gear before the vehicle has come to a complete stop. Many drivers shift directly into reverse gear to demonstrate smooth operation, which can severely damage transmission gears and lead to gear grinding faults over time; Avoid frequent D gear use on steep slopes. Automatic transmission vehicles may overheat under high load or shift prematurely, causing weak climbing power. Use manual mode to limit low gears or sport mode to protect the transmission; Do not tow long distances. When an automatic transmission vehicle breaks down, use a flatbed tow truck with the vehicle in N gear rather than towing directly with a rope.

What Causes the Engine to Require Multiple Attempts to Start After Refueling?

The reasons why the engine requires multiple attempts to start after refueling include: 1. Electrical issues: Possible faults in the spark plugs or ignition coils may cause one or multiple cylinders to fail to ignite, leading to engine stalling. However, the likelihood is relatively low since stalling typically occurs when multiple cylinders fail to ignite simultaneously. 2. Fuel pump problems: Engine stalling due to lack of fuel supply is often caused by the fuel pump. A stuck or faulty fuel pump can suddenly stop supplying fuel, resulting in stalling. 3. Incorrect starting method: For example, failing to close the choke during a cold start or not pressing the float sinker can cause the air-fuel mixture entering the cylinder to become too lean, making it difficult to start the engine.
