Reasons for abnormal noises after a vehicle drives through water: water entering the brake pads, foreign objects trapped between the brake pads and calipers, water ingestion in the exhaust pipe, debris stuck in the chassis, etc. The car should be driven out and parked in a dry area, followed by inspection of the relevant components. Below are the detailed explanations: Water entering the brake pads: If the vehicle drives through shallow water and water splashes onto the brake pads, abnormal noises during braking are normal. In this case, simply continue driving normally, and the noise will disappear once the water on the brake pads dries. Foreign objects trapped between the brake pads and calipers: If the vehicle drives through shallow water and plastic bags, mud, or other debris get stuck between the brake pads and calipers, it can also cause abnormal noises during braking. Cleaning the brake pads will resolve this issue. Water ingestion in the exhaust pipe: If the vehicle drives through deep water and water enters the engine through the exhaust pipe, it can prevent the fuel and air mixture from burning properly, resulting in abnormal noises. In this situation, the vehicle should be driven out immediately, and the engine should be cleaned to avoid engine failure or even complete engine damage. If the vehicle stalls in a waterlogged area, do not attempt to restart it. Instead, arrange for a tow truck to pull it out immediately to prevent further damage. Debris stuck in the chassis: If foreign objects get stuck in the chassis after driving through water, abnormal noises may occur while driving. Cleaning the chassis will resolve this issue.

How to Check Tire Pressure in Octavia?

Octavia can check tire pressure through a tire pressure monitor. It is recommended to measure the tire pressure when the tires are cool. The standard tire pressure values for Octavia can be found in the vehicle's user manual, on the label near the B-pillar of the driver's door, or in the drawer beside the driver's seat. Additional Information: 1. Most Octavia models are equipped with a tire pressure warning system. When the tire pressure is abnormal, the vehicle will alert the driver. Octavia's tire pressure monitoring system is always active. When the tire pressure warning light comes on, check the pressure of all four tires. 2. If the pressure is abnormal, after identifying the cause, you need to reset the system. The reset button is located in front of the gear lever (set). With the ignition on or in idle mode, press and hold the button for 3 seconds. The dashboard indicator will flash once, accompanied by a "ding" sound, indicating that the initialization is complete.

Is the Envision's dual-clutch transmission dry or wet?

The Envision's dual-clutch transmission is dry-type. In a dry dual-clutch system, the clutch plates are in direct contact with the engine flywheel, whereas in a wet dual-clutch system, the clutch plates are immersed in transmission fluid. The clutch, located between the engine and the transmission, acts as a switch for power transfer between the two. Its primary functions are to ensure smooth vehicle starts, reduce impact loads on transmission gears during gear shifts, and prevent drivetrain overload. The Envision is positioned as a midsize SUV. In terms of exterior features, it comes equipped with an intelligent air shutter grille, aluminum roof rails, chrome dual exhaust pipes, and multi-function exterior mirrors. Regarding body dimensions, the Envision measures 4686mm in length, 1839mm in width, and 1660mm in height, with a wheelbase of 2750mm.

How to Reset Tire Pressure on Cadillac XTS?

To reset the tire pressure on a Cadillac XTS, simply press the unlock button on the remote three times, then simultaneously hold the unlock and lock buttons. After a while, a prompt will sound twice—release the buttons. Then, release air from the tires until a single prompt sound is heard, followed by the right tire. After that, for the left rear and right rear tires, wait for four prompt sounds. Finally, refill the tires to the normal pressure. Additional Information: 1. Direct tire pressure monitoring systems use pressure sensors installed in each tire to directly measure tire pressure. The data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure readings. If the tire pressure is too low or there is a leak, the system will automatically alert the driver. 2. Indirect tire pressure monitoring works by detecting when a tire's pressure drops, causing the vehicle's weight to reduce the rolling radius of that tire, making it rotate faster than the others. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect tire pressure warning systems essentially rely on calculating the rolling radius of the tires to monitor pressure.

Why is the brake sound screeching?

Screeching brake sounds may be caused by worn brake pads, foreign objects in the brake pads, or the break-in period of newly replaced brake pads. Worn brake pads: When a car has been used for many years or has high mileage, the brake pads may age and wear out, leading to abnormal noises. In this case, the brake pads should be replaced at a 4S shop. Foreign objects in the brake pads: If the car has traveled through muddy or bumpy roads, small stones or other debris may become lodged in the brake pads, causing friction and noise. This situation can be resolved by cleaning the brake pads. Break-in period of new brake pads: When new brake pads are installed, there may be some noise initially. This usually resolves after driving for a while to allow the pads to break in. If the noise persists after some time, it is advisable to visit a 4S shop or repair shop for professional inspection.
