How to Fix Yellowed Car Headlight Covers?

If the car's headlight covers have turned yellow, they can be restored through sanding or polishing. If you prefer not to sand or polish, you can directly replace them with new covers. Car headlight covers are made of plastic, and plastic products tend to yellow over time. If the car is frequently parked in direct sunlight, the yellowing of the headlight covers will be more noticeable. Here are the detailed steps: 1. If the headlight covers have yellowed, you can take them to a professional service for polishing or sanding, or you can replace them with new covers. 2. When replacing the covers, note that some vehicles' headlight covers are not sold separately, while others are. If only the covers are being replaced, it's essential to find a professional shop, as the seal of the headlights may weaken after replacement, potentially allowing rainwater to enter during rain. Therefore, ensure a professional shop handles the sealing properly. 3. It's advised not to modify the headlights casually. Installing high-heat bulbs can accelerate the aging of the covers and pose safety risks. Unauthorized modifications may also affect the vehicle's annual inspection. 4. During regular use, avoid parking the car in direct sunlight, as this speeds up the aging of many rubber and plastic components, as well as the paint.

Is There Any Harm in Modifying a One-Button Start System?

Modifying a car to have a one-button start system does not affect the vehicle. It simply changes the key switch start to a button switch start. The biggest advantage is that you don't need to hold the key in your hand—just keep it in your pocket or bag, eliminating the hassle of searching for the key every time. Below is some relevant information: 1. One-Button Start: The one-button start device is part of a smart car system, serving as a button mechanism to simplify the starting process and also allowing the engine to be turned off. This device can be installed either in place of the original key ignition or as an independent panel modification. 2. Considerations: The system operates via software-based one-button start. There are three main points to note when installing a one-button start system: the wiring connections under the ignition switch, the positioning of the button, and the handling of the steering wheel lock.

Why is the car not getting power?

Introduction to the reasons why a car is not getting power: The entire car not getting power may be due to a blown main fuse, a dead battery, or circuit issues. Below are the specific details and solutions: 1. If the screen is completely black and does not turn on, check if the car's original fuse is blown. If the fuse is blown, replace it. 2. Check if the navigation buttons are stuck, including the RSET button. Stuck buttons can also prevent the system from turning on. If skilled, you can remove the navigation unit and check if the tail fuse of the navigation is blown. If it is blown, replace it. 3. If the screen is black and does not turn on, use a multimeter to measure whether the B+ and ACC voltages are normal (12V). If the voltage is normal, then the issue is an internal fault of the device and requires opening it for repair.

How to Handle Vehicle Skidding on Muddy Roads?

When a vehicle skids on a muddy road, correct the direction and gently apply the brakes. Here is more relevant information: 1. Do not slam on the brakes: Avoid slamming on the brakes to prevent the wheels from locking up, which would only support the vehicle but completely lose the ability to counteract the skid. Especially if the front wheels lock up, although they retain the function of changing direction, they cannot guide the vehicle's steering, leaving it in a completely out-of-control state. 2. Do not turn the steering wheel in the opposite direction of the skid: The correct method is to adjust the steering wheel appropriately in the direction the rear of the vehicle is sliding. The steering action should be quick and light. 3. Stay calm and operate correctly: If the vehicle skids, remain calm. If the skid is caused by braking, immediately stop braking. If the vehicle skids to the left, turn the steering wheel to the left, and vice versa, but the action should not be too large, otherwise, the vehicle may skid in the opposite direction. Do not use the handbrake, as most vehicle handbrakes act on the rear wheels, which can easily cause skidding.

Must downshifting be done gear by gear?

During the deceleration and downshifting process in the Subject 3 driving test, it is necessary to downshift gradually gear by gear, and direct gear-skipping downshifts are not allowed. Otherwise, there may be a mismatch between speed and gear. Key challenges in the Subject 3 test: 1. Speed and gear mismatch: Before shifting gears, it is essential to adjust the speed to match the target gear, and then proceed with the shift. 2. Deviation in straight-line driving: Many learners intentionally slow down due to concerns about not driving in a straight line, which is not advisable. Doing so actually increases the likelihood of the vehicle deviating from its intended path. Therefore, maintaining a reasonable and steady speed is recommended. 3. Parking more than 30cm from the curb: The Subject 3 test explicitly requires that the distance between the parked vehicle and the curb should not exceed 30cm. However, this distance is difficult for learners to judge, and many end up parking too far from the curb. Hence, special attention is needed for this aspect.
