Running out of fuel in a car may cause damage to the fuel pump. When the car's fuel warning light comes on, the vehicle can typically continue to drive for about 50 kilometers. However, it is advisable not to wait until the fuel warning light appears to refuel, as this can have certain negative effects on the car. More details on car usage are as follows: 1. Refuel in advance: Do not wait until the car runs out of fuel before refueling. When the fuel warning light comes on, it means the fuel pump is exposed above the fuel level. The fuel pump relies on the gasoline in the tank for cooling during operation. The amount of heat absorbed is proportional to the volume of fuel in the tank. If the fuel level continues to drop, it may damage the fuel pump and shorten its lifespan. 2. Avoid overfilling: Do not overfill the fuel tank, especially during hot summer conditions. Gasoline expands when heated and can evaporate into vapor. If there is no extra space in the tank to store the vapor, it can lead to waste, environmental pollution, and even increased fuel consumption.

Is it necessary to use turn signals when changing lanes?

Changing lanes requires the use of turn signals to alert other vehicles of your intention to change lanes. Here are the relevant details: 1. Regulations: Article 57 of the 'Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China' stipulates that when a motor vehicle turns left, changes lanes to the left, prepares to overtake, leaves a parking spot, or makes a U-turn, the left turn signal must be activated in advance. When turning right, changing lanes to the right, returning to the original lane after overtaking, or pulling over to the roadside, the right turn signal must be activated in advance. 2. Precautions for lane changing: When entering the traffic lane from an acceleration lane, observe the conditions in the traffic lane and merge behind normally moving vehicles when traffic is sparse. If a normally moving vehicle is closely following, control your speed and enter the traffic lane only after all vehicles have passed; do not abruptly cut in. Lane changes must always be preceded by activating the turn signal.

What is the cause of the Buick fault code 136?

ode136 code indicates a parking assist system malfunction. If this issue occurs, you can try disconnecting and reconnecting the battery cables, as the problem is mainly related to the power supply voltage of the assist system's radar, camera, and other wiring. Alternatively, it could be due to a malfunction in the camera, sensors, or distance measurement equipment. In such cases, it is advisable to visit a professional auto repair shop for timely repairs. The automatic parking assist system is designed to facilitate automatic parking. Among various automotive accessories, those related to reversing safety are particularly noteworthy. Models equipped with reversing assist systems are often considered a hallmark of high-end vehicle configurations. Different automatic parking systems employ various methods to detect objects around the vehicle. Some systems use sensors installed around the front and rear bumpers, which can act as both transmitters and receivers. These sensors send signals that reflect off obstacles near the vehicle. The onboard computer then calculates the time taken for the signal to return to determine the obstacle's position. Other systems use cameras or radar mounted on the bumpers to detect obstacles. However, the end result is the same: the vehicle detects parked cars, the size of the parking space, and the distance to the curb, then maneuvers the car into the parking spot.

Should a Slipping Transmission Be Repaired or Completely Replaced?

Transmission slipping can be repaired. Below are the relevant details: 1. Transmission Slipping: Slipping is one of the most common issues in automatic transmissions. Although slipping in an automatic transmission is often accompanied by severe wear or even burning of the clutch or brake friction plates, various inspections and tests should be conducted first to identify the true cause of the slipping. 2. Checking Oil Level: For a slipping transmission, the first step is to check the hydraulic oil level. If the oil level is too low or too high, it should be adjusted to the normal level before further inspection. If the automatic transmission stops slipping after the oil level is adjusted to normal, there may be no need to dismantle and repair the transmission.
