To activate the horn sound when locking the car with the remote key, simultaneously press the unlock and lock buttons for 3 seconds until the light flashes. Settings - Sound - Screen Lock Sound - Play sound when locking and unlocking the screen. To ensure the horn sounds properly, it should not be rigidly mounted. A leaf spring or rubber pad must be installed between the horn and the fixed bracket.

What Causes Leakage at the Roof Light?

Roof leakage can be caused by the following reasons: 1. Sunroof leakage: There are generally two scenarios for sunroof leakage. One is that small sand particles or dust in the sunroof drainage channel cause blockages. The other is that the sunroof sealing strip has been "lifted" or displaced. Therefore, it is advisable to regularly clean the sunroof to maintain the cleanliness around the drainage channel. Additionally, during routine car washes, use high-pressure air jet equipment to blow air in the direction of the drainage pipes to remove any accumulated dirt. 2. Failure of automotive waterproof adhesive causing leakage: Leakage often occurs at the openings of doors and the trunk. This is mostly due to issues with the waterproof strips, such as deterioration, aging, or cracking of the rubber waterproof strips, allowing rainwater to seep in. Reapplying adhesive specifically designed for waterproof strips can completely prevent leakage. 3. Blocked drainage pipes causing interior leakage: The most common cause of interior leakage is the blockage of the drainage pipes beneath the front windshield. Infrequent car washing or prolonged parking under trees can lead to the accumulation of dust, leaves, mud, and other debris in the drainage pipes. Over time, these blockages can obstruct the pipes, preventing proper drainage. During heavy rain, water may backflow into the car, causing leakage. 4. Failure of floor plug seals causing leakage: While rainwater usually leaks from above, it can also seep in from below due to issues with the floor plug seals. The floor has several holes where plug seals are embedded from above. If these seals become misaligned, the interior becomes directly connected to the ground, allowing rainwater to seep in during heavy rain. If the floor gets wet, this should be the first area to suspect.

How to Quickly Ventilate When Smoking in the Car?

You can slightly crack open the window on the side where you are sitting. The positive pressure inside the car will help push the smoke out efficiently, but avoid opening it too wide. This method of opening the window is highly practical as it allows for rapid air circulation inside the car, effectively eliminating odors. When driving at high speeds on the highway, it's best not to open the windows too much. If you need to ventilate, it's advisable to only open the window on the side where the odor is present.
