H4 LED headlights perform better when the LED chips are oriented left and right. Below is relevant information about LEDs: 1. Introduction: LED automotive lights refer to the use of LED technology for both interior and exterior lighting in vehicles. Exterior lighting involves thermal limits and EMC issues, along with numerous complex standards for load testing. LED automotive lights can be widely used to create the vehicle interior environment, with a lifespan of 50,000 hours. The robust structure of LEDs makes them less susceptible to vibration, and there is no significant decrease in light output brightness during use. 2. Suitable applications for LED automotive lights: LED automotive lights are suitable for various automotive electronic lighting applications, including headlights (high beam and low beam), fog lights, taillights, brake lights, turn signals, daytime running lights, pedal illumination, instrument panel lights, license plate lights, door lights, interior lighting, marker lights, navigation, entertainment systems, backlighting, and indicator lights.

Where is the child lock located on the Elysee?

The child lock on the Elysee is located below the rear door lock, on the side of the door. There is a protruding switch that can be toggled up and down to activate or deactivate it. Each rear door has its own separate switch. The child lock cannot be disengaged from inside the car; you must lower the window and manually open the door from the outside to deactivate it. When the child lock is engaged, the door cannot be opened from the inside and can only be opened normally from the outside. This feature is designed to prevent children from playing with the door handle and accidentally opening the door when unsupervised. The Elysee is a compact 4-door, 5-seater sedan under Dongfeng Citroen, with dimensions of 4427mm in length, 1748mm in width, and 1476mm in height, a wheelbase of 2652mm, and is equipped with a 5-speed manual transmission.

Why is it difficult to start a car when it's hot?

There are several reasons why a car is difficult to start when it's hot: 1. Fuel injector leakage: While fuel injection is normal, leakage constitutes additional fuel supply. The more severe the injector leakage, the richer the air-fuel mixture becomes, making it difficult to start a hot engine. 2. Damaged carbon canister solenoid valve: During hot starts, fuel atomization is normally sufficient without needing additional fuel vapor. If the carbon canister continues to supply fuel vapor to the intake tract, it will cause an overly rich mixture, leading to difficult starting. 3. Fuel quality: After a hot engine is shut off, the high temperature in the engine compartment can cause volatile fuel to form high vapor pressure in the fuel rail. When this pressure exceeds the fuel system pressure, vapor lock occurs, resulting in excessively lean fuel vapor from the injector and making starting difficult.

How many years do you have to complete the driver's license test?

The driver's license test must be completed within 3 years. However, the 3-year validity period is calculated from the date when the applicant passes the subject one test and obtains the learning driving certificate. According to the regulations, the remaining subjects must be completed within 3 years. Otherwise, all the passed subject test results will be invalidated. Those who still need to obtain a driver's license will have to re-register and retake all the subjects. Applicants who learn to drive on the training ground and roads must obtain a learning driving certificate as required. A driver's license, also known as a driving license, is a document issued by the government transportation department to certify that a person is qualified to drive. It is usually a card. To obtain a driver's license, the applicant must meet the minimum age requirement and pass the driving test.

What causes the sudden disappearance of the reversing camera?

The sudden disappearance of the reversing camera can be attributed to the following reasons: 1. Poor line contact. It is necessary to promptly inspect the connection points between the wiring and the vehicle's installation to check for loose connections. If present, this will naturally lead to abnormal imaging of the reversing camera, which can be resolved by securing the connection properly. 2. It could also be due to aging of the video power cable. Trying to replace it with a new power cable might help. 3. Prolonged use of the reversing camera may result in poor chip photosensitivity, even leading to a snowy screen effect. 4. There might be defects in the vehicle's circuit design. Any abnormalities with the reversing camera should be inspected and repaired at a service center, or the camera may need to be replaced directly.

Is the Oil Filler Cap Sucking or Blowing Air?

Whether the oil filler cap is sucking or blowing air can be divided into two situations: when the engine is idling, opening the oil filler cap should result in air blowing out; the oil filler port is located on the engine's valve cover, and this port is used for adding engine oil. Engine oil is something every car owner comes into contact with during vehicle use, and without it, the engine cannot operate normally. Engine oil is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. Engine oil is used for lubricating internal combustion engines, with its main functions being to reduce friction and wear on moving parts and to clean sludge and varnish from the engine.

Where to Place the Fire Extinguisher in a Sedan?

The fire extinguisher in a sedan should be placed in the trunk. If you are concerned about the extinguisher tipping over or being impacted due to vehicle movement and bumps, you can secure it with a net. If a net is not available, you can purchase Velcro straps or mounting brackets designed for securing car fire extinguishers online. A fire extinguisher is a portable firefighting tool and one of the common fire prevention facilities, categorized into handheld and wheeled types. Different types of fire extinguishers contain different filling components, including foam, dry powder, and halon. Precautions for using a fire extinguisher include: 1. During transportation and storage, avoid placing it upside down, exposure to rain, sunlight, strong radiation, and contact with corrosive substances; 2. The storage location should be kept dry and ventilated to prevent the cylinder from becoming damp and corroding.
