ETC needs to be reinstalled and reactivated for use after falling off. The installation process for the ETC device is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly illuminate. 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 "Tag Invalid" appears when inserting and removing twice without attaching the electronic tag, 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.

How to Turn On the Rear Fog Light?

Rotate the light control knob to the "position light" or "low beam" position, then pull the knob outward to the second position. At this time, the vehicle's rear fog light will turn on. When the rear fog light is activated, the front fog light will also turn on simultaneously. The control logic for fog lights is as follows: 1. Front fog light: If equipped, the front fog light can be turned on and off independently. 2. Turn on the headlight or front fog light first: The rear fog light can only be turned on when the headlight (high beam or low beam) or front fog light is activated. 3. Rear fog light: The rear fog light can be turned off independently, and it can also remain continuously lit.

Does the Haval F5 have four-wheel drive?

Haval F5 does not have four-wheel drive. Taking the 2019 Haval F5 as an example, all models of the Haval F5 are front-wheel drive. Not all SUVs are equipped with a four-wheel drive system. Equipping a four-wheel drive system increases the vehicle's cost, which naturally leads to a higher selling price. Many models, constrained by cost factors, opt for front-wheel drive. Here is some information about four-wheel drive: 1. Four-wheel drive refers to a vehicle maintaining a four-wheel drive form throughout the entire driving process, with the engine's output torque distributed to the front and rear wheels at a fixed ratio. This drive mode ensures good off-road and handling performance at all times, but it cannot adjust torque distribution based on road conditions and has higher fuel consumption. 2. Four-wheel drive is divided into the following three types: on-demand four-wheel drive, part-time four-wheel drive, and full-time four-wheel drive.

How often should hybrid batteries be replaced?

The power system of hybrid vehicles is designed to last the lifetime of the car, with an 8-year or 200,000-kilometer warranty. There are cases abroad where taxis have run over 1.3 million kilometers without battery replacement, as well as instances where batteries were replaced within 3-4 years. Below are additional tips for battery maintenance: 1. Turn off electrical devices before parking and shutting off the engine: Leaving lights, audio systems, air conditioning, and other electrical devices on for extended periods after the engine is off is very harmful to the battery. 2. Avoid long-term vehicle inactivity: If the vehicle is not used for a long time, the battery's charge will gradually decrease, making it difficult to start the engine the next time you drive. 3. Regularly clean the battery: Use a damp cloth to periodically wipe the exterior of the battery, removing dust, grease, and other contaminants from the panel and the positive and negative terminals that could cause leakage, preventing the accumulation of corrosive acidic powder.

What is the solution when the steering wheel is locked and the key cannot be turned?

The solutions for a locked steering wheel and an unturnable key are as follows: 1. Insert the key, then turn the steering wheel in the opposite direction, and then turn the key. 2. When starting the car, do not press the brake pedal first. Press the keyless start button once, then turn the steering wheel left and right, press the brake pedal, and press the start button again. Additional related information is as follows: 1. Steering wheel lock is a simple anti-theft feature. When the car is turned off, turning the steering wheel from the straight position to one direction (usually to the left) by a certain angle will cause a click sound, locking the steering wheel. 2. In the locked state, the steering wheel cannot be turned, the key cannot be turned, and the car cannot be started, achieving the anti-theft function.

How Many Years Can a BMW Last?

2020 vehicle scrapping regulations have abolished the mileage limit for non-commercial passenger vehicles, while setting the maximum mileage for private cars at 600,000 kilometers. Therefore, theoretically, a BMW has no usage time limit as long as it passes annual inspections. However, there are practical limitations: 1. Mandatory scrapping without passing inspections: For vehicles older than 15 years, if they fail to pass inspections for three consecutive cycles (1.5 years), they will be mandatorily scrapped. Additionally, these vehicles require biannual inspections, which can be cumbersome, leading many owners to opt for scrapping. After 20 years, inspections increase to four times annually. 2. Mileage cannot exceed 600,000 km: Vehicles will be mandatorily scrapped if they fail safety or emission standards or exceed 600,000 kilometers. 3. Difficulty in obtaining spare parts: After a certain period, car models are discontinued, making spare parts hard to find. Repair costs also rise significantly, often prompting owners to scrap the vehicle even before reaching the mandatory scrapping age.

How to Solve Excessive Vehicle Exhaust Emissions?

Solutions for excessive vehicle exhaust emissions are as follows: 1. Clean carbon deposits: Severe carbon buildup in the car can block the circuits, leading to non-compliant exhaust emissions. Therefore, it is essential to clean the car regularly. 2. Air filter: The air filter prevents polluted particles in the air from entering the car's cold air system, ensuring the normal operation of car components. After prolonged use, the air filter also needs regular cleaning. Cleaning the air filter can effectively avoid pollutants in the air, thus preventing any impact on the car's performance. This reduces pollutants and impurities in the exhaust emissions, avoiding non-compliance. 3. Add additives to change fuel composition: Adding methanol fuel below 15% to gasoline or using water-gasoline fuel with 10% water content can reduce or eliminate pollution effects of CO, NOx, HC, and lead dust to some extent. If "methanol fuel" is used, which is a mixture of methanol and other alcohols with gasoline, and when methanol accounts for 30% to 40% of the mixture, pollutants in the vehicle's exhaust emissions can be almost completely eliminated.
