How to Adjust the Ambient Lighting in Mercedes-Benz E300L?

The common method is to use the button located next to the headlight switch. This button can adjust both the instrument panel lighting brightness and the ambient lighting brightness simultaneously. Below is detailed information about the Mercedes-Benz E300L: 1. Size: The wheelbase of the new-generation Mercedes-Benz E-Class will be extended by 14cm. Overseas, the new Mercedes-Benz E-Class has a length of 4868mm and a wheelbase of 2874mm. After the 14cm extension, the wheelbase will reach 3014mm. 2. Exterior and Interior: In terms of appearance, it draws inspiration from the second-generation design, enhancing the sense of premium quality. The overall lines are more rounded. 3. Applicability: The Mercedes-Benz E300L model is not only suitable for young people but also ideal for business use.

Can a Burned-out Battery Be Repaired?

Car batteries can be repaired if they are damaged. Here is an introduction to battery repair: 1. Inspect the faulty battery: Determine the type of fault, such as sulfation or discharge, and use a battery repair device to fix it. 2. Causes of battery damage: Battery capacity typically declines due to sulfation, which can be caused by prolonged high-current discharge, operating in a discharged state, leaving the battery in a discharged condition for extended periods, or lack of water. Below is additional information on battery repair methods: 1. Repair method: Perform water replenishment maintenance. Whether it's a maintenance-free dry battery or a water-refillable wet battery, maintenance is necessary. 'Maintenance-free' does not mean no maintenance at all, just that it is less frequent. 2. Repair approach: Generally, battery repair involves using a battery repair device and battery repair fluid. If these are unavailable, simply adding water can serve as basic maintenance. However, the water used must meet specific requirements—tap water, groundwater, or mineral water are unsuitable; only distilled water, deionized water, or high-purity water should be used.

What is the normal tire pressure?

According to the provisions and requirements of the international GBT2978-2008 standard, the tire pressures for different tires are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: Should not exceed 3.5bar. Normal tire pressure range in winter: In winter, the tire pressure should be based on the standard tire pressure of the car tires, with an appropriate increase of about 0.2bar. Normal tire pressure range in summer: Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1bar lower than the standard to avoid tire blowouts due to high temperatures. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; It accelerates the local wear of the tread pattern in the central part of the tire, reducing the tire's lifespan; The vibration of the car body increases, indirectly affecting the lifespan of other components; It causes excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the car during driving; Puncture resistance decreases. When encountering sharp objects such as nails or glass on the road, they can easily penetrate the tire, and the impact can cause internal cracks and explosions, leading to tire blowouts.

What are the precautions for driving in heavy fog?

Precautions for driving in heavy fog: 1. Use lights correctly: When driving in fog, it's best to turn on all the lights on the car (except for high beams). If driving on the highway or in very thick fog, also turn on the hazard lights. Avoid using high beams in foggy conditions because high beams shine upwards, and the light scattered by the fog can create a blinding white haze in front of the car, impairing visibility. 2. Use the horn for alerts: While constantly honking the horn during normal driving is not only disturbing but also impolite, using the horn in foggy conditions can alert pedestrians on the road that a car is approaching, prompting them to take caution. 3. Avoid slamming on the brakes: Refrain from slamming on the brakes because fog makes it difficult to judge distances. Sudden braking can make it hard for the vehicle behind to gauge the distance, potentially leading to a rear-end collision. The best way to avoid emergency braking is to drive slowly and maintain a longer distance from the vehicle ahead. If emergency braking is necessary ahead, gently press the brakes several times in succession to control speed, effectively alerting the vehicle behind to pay attention.

What to Do If the ETC Device Falls Off?

ETC needs to be reinstalled and reactivated after falling off. The installation process for the ETC device is as follows: Upon receiving the device, first check whether the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly turn on. The OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning properly. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then, peel off the adhesive backing of the OBU and attach it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield, ensuring the chip is inserted into the OBU device. Method to activate the ETC device: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth On." If the screen shows "Tag Invalid" when inserting and removing the card twice without the tag attached, this is normal and does not affect activation. Alternatively, press the button on top of the electronic tag to enable Bluetooth directly. Turn on your phone’s Bluetooth and open the corresponding mobile app (usually a download QR code is provided on the electronic tag), then navigate to the device activation interface. Click "Connect Device" and wait patiently for the "Connection Successful" prompt. Once connected, upload a photo of the vehicle’s front to complete activation.

What is the difference between cast and forged wheels?

Here are the differences between the two: Price: Compared to cast wheels, forged wheels have broken grains and forged structures, while cast wheels have dendritic grains and cast structures. In terms of individual mechanical performance indicators, forged wheels generally improve by 30% to 50%, with some indicators being several times higher. Therefore, wheels of the same model that are forged are usually much more expensive than those made by low-pressure casting. Appearance: Whether cast or forged, after various processes, it is generally difficult to distinguish much difference in appearance unless marked. However, forged wheels usually have simpler and more refined spokes. Performance: Low-pressure cast wheels have good filling properties, fewer shrinkage cavities, and higher density because they are filled and solidified under pressure. Forged wheels, on the other hand, have grain flow directions aligned with the stress direction, resulting in higher strength, as well as significantly better toughness and fatigue strength compared to cast wheels.
