Which is better for a dash cam: plugging into the cigarette lighter or hardwiring?

It is better to plug the dash cam into the cigarette lighter power source. Using the cigarette lighter does not require modifying the car's wiring or dismantling the center console panel (removing the center console panel may lead to rattling noises later). Below is the installation method for a dash cam: 1. First, determine the installation position of the dash cam. Route the cable from below the center console to the edge of the windshield, then extend it near the rearview mirror; 2. Determine the optimal wiring route based on the length of the power cable; 3. Tuck the power cable of the dash cam into the gap of the headliner; 4. Then tuck the cable into the door seal strip and reinstall the seal strip properly; 5. Insert the power cable into the seal strip until it reaches the bottom of the dashboard and let the cable hang out; 6. Finally, plug it into the cigarette lighter power source.

What to Do When ETC Fails to Respond?

Here are the solutions for ETC failing to respond: 1. Do not drive too fast when passing through the ETC lane; 2. Check if the ETC device is loose, fallen off, or has been self-disassembled causing the anti-tamper switch to pop out, requiring a reset of all data; 3. Charge the ETC device; 4. Check if it is the ETC card for this vehicle. Additional information: The installation method for ETC is: 1. Check if the ETC card and OBU are damaged, press the anti-tamper button on the OBU, the red light will briefly turn on, and the OLED screen will display 'Please insert card', indicating the device is functioning normally; 2. Clean the front windshield, ensuring the glass surface is dry, peel off the protective film on the back of the OBU adhesive, stick it to the installation position, and press firmly for 2 to 3 minutes; 3. Insert the ETC card with the front facing the driver and the back facing the front glass, placing the chip into the device.

What are the precautions for vehicles passing through tunnels?

Here are the precautions for vehicles passing through tunnels: 1. Before entering the tunnel, carefully observe the height and width limit signs and text instructions at the entrance. Vehicles that do not meet the requirements are not allowed to enter the tunnel; 2. Before entering a one-way tunnel, carefully observe whether there are oncoming vehicles. When allowed to pass, sound the horn appropriately or turn on the width indicator lights; 3. When entering a two-way tunnel, drive on the right side, turn on the lights as needed, pay attention to oncoming vehicles, and avoid honking inside the tunnel; 4. Overtaking, reversing, making U-turns, and parking are prohibited inside the tunnel. In case of a vehicle breakdown, turn on the width indicator lights and tail lights, and try to move the vehicle outside the tunnel.

Is wheel balancing necessary after changing tires?

Wheel balancing is required after changing tires. A wheel consists of two parts: the tire and the rim. Due to manufacturing processes, the mass distribution of each part cannot be completely uniform. When the car is driven at high speeds, the rapid rotation of the wheels can create dynamic imbalance, causing body and steering wheel vibrations. The following are the functions of car tires: 1. Tires serve as the medium for transmitting forces between the vehicle and the road surface, transferring driving force, braking force, steering force, etc., thereby enabling the car's driving, braking, and steering operations. 2. Supporting the vehicle load. The vehicle's load causes the tire to sink until the average pressure on the tire's contact area balances with the internal inflation pressure. 3. Reducing and absorbing vibrations and impact forces during driving, preventing early damage to car components caused by severe vibrations. At the same time, they adapt to the vehicle's high-speed driving conditions, reduce driving noise, and ensure driving safety, comfort, handling stability, and fuel economy.

What are the differences between imported cars and joint-venture cars?

Here are the differences between imported cars and joint-venture cars: 1. Different channels: Imported cars are imported as complete vehicles; joint-venture cars are either domestically produced as complete vehicles or assembled in China after importing some parts, with some models undergoing minor modifications. 2. Different configurations: Imported cars come with complete configurations; joint-venture cars may omit features such as bumpers, anti-collision beams, daytime running lights, and ESP, which can affect vehicle safety. Additional information: Imported cars refer to vehicles purchased by traders from overseas markets and introduced into the Chinese market for sale without authorization from the brand manufacturers. Joint-venture cars are produced by Chinese and foreign investors jointly, where the Chinese side provides land, factory usage rights, and capital, while the foreign investors contribute the brand, technology, capital, talent, etc., for domestic assembly and sales.

How to Deactivate the Anti-lock Braking System?

ABS (Anti-lock Braking System) remains in a constant standby state, so it cannot be deactivated in regular civilian vehicles. However, on some high-performance models, the ABS can be deactivated by switching the driving mode to drift mode. Below are the usage instructions for the ABS Anti-lock Braking System: 1. Always keep the brake pedal firmly pressed without releasing it to ensure sufficient and continuous braking force, allowing the ABS to function effectively. 2. Maintain a safe following distance. Under normal circumstances, the minimum following distance should not be less than 50 meters. When the speed exceeds 50 km/h, the minimum following distance should match the speed value. For example, at 100 km/h, the minimum following distance is 100 meters, and at 120 km/h, it should be 120 meters. 3. Familiarize yourself with the ABS in advance to prepare for and adapt to the brake pedal vibrations when the ABS is active. 4. Read the vehicle owner's manual beforehand to better understand the various operational instructions provided by the manufacturer for vehicles equipped with ABS.
