The subframe is located below the engine. The subframe, also known as the auxiliary frame, is a bracket that supports the front and rear axles and suspension. The main function of the subframe is to support the engine. While supporting the engine, it is connected to the chassis components. It is a very important part of the engine compartment. Once damaged, it needs to be replaced, and improper maintenance can affect its performance. The subframe also plays a role in supporting the engine and transmission, and can increase the rigidity of the vehicle chassis to a certain extent. The material of the subframe is generally steel, while high-end models use cast aluminum alloy. To determine whether the subframe is deformed, tools are generally required to compare the diagonal lengths. The subframe consists of the axle, differential, and other components, forming an axle assembly. The suspension is connected to the main frame either rigidly or flexibly (via rubber or hydraulic pads) through the subframe. Additionally, only vehicles with a unibody design have a subframe, while vehicles with a body-on-frame design do not.

Why can't the BYD one-button start ignite the engine?

The reasons why the BYD one-button start cannot ignite the engine may include the following: 1. Key demagnetization: Frequently placing the car key near electronic devices such as mobile phones, computers, or TVs can interfere with the low-intensity radio waves in the key. Alternatively, if there are strong radio waves nearby, such as from TV towers, airports, or power plants, the one-button start may "fail." 2. Car key battery depletion: If the key shows signs like reduced remote control distance or decreased sensitivity, it is a warning that the key battery is running low. In a state of battery depletion, the one-button start function cannot operate properly, and the battery should be replaced as soon as possible. 3. Vehicle malfunction: In extreme cases such as fuel system issues, dead battery, or electronic component short circuits, it is advisable to directly call the 4S store staff for assistance.

What is the button below the windshield wiper of the Lamando?

The button below the windshield wiper of the Lamando is mainly used for switching sub-items and reset confirmation, and its specific functions are used in conjunction with the button at the end of the wiper. The windshield wiper is a device used to remove raindrops and dust attached to the vehicle's windshield to improve the driver's visibility and enhance driving safety. How to use manual windshield wipers: 1. When the rain is not heavy, do not rush to turn on the wiper, because there is insufficient moisture on the windshield at this time, and the wiper will dry wipe, which will only smear the dirt and damage the wiper and scratch the windshield. When turning it on, spray windshield washer fluid first and then turn on the wiper. 2. When the rain is heavy, it is necessary to increase the wiper frequency in time. When the rain is heavy, the visibility is poor while driving. You should pull over and wait for the rain to lighten before continuing. Don't forget to turn on the fog lights and hazard lights when parking.

Will the Air Conditioner Consume Power If Left On After Removing the Car Key?

Air Conditioner will not operate. Below is the relevant information: 1. Air Conditioner operates with the engine: The car's air conditioner runs along with the engine. If the engine is not working, even if the air conditioner is not turned off, it will not operate. 2. Increased load on the starter: The power for the air conditioner comes from the engine. After removing the key, the engine stops running, and naturally, the air conditioner loses power and stops. However, when starting the car again, it is best to turn off the AC switch, otherwise, the load on the starter will be relatively large. Additional information: If the car is turned off but the air conditioner is forgotten to be turned off, it may lead to the car battery draining. There are two scenarios: 1. Forgetting to turn off the air conditioner before turning off the engine; 2. Forgetting to turn off the lights and other onboard electrical appliances.
