What are the reasons why a Lexus suddenly won't start?

Lexus suddenly won't start for the following reasons: Gear in P position: Check if the gear is in P position. Some models won't start if the gear is not in P position, so you need to shift it back to P. Dead battery: Check if it's caused by a dead battery, such as turning on the headlights to see if they light up, or pressing the horn to hear if there's any sound. If it's due to a dead battery, you'll need to jump-start it with another car. If you're not familiar with the operation, it's best to call for roadside assistance for a jump-start, such as from a 4S shop, gas station, or even a car wash. Additionally, you can contact your insurance company, as they usually offer free jump-start rescue services during the car insurance coverage period. Spark plug failure: Check if the spark plugs are blackened or oxidized. If so, wipe off the oxidation layer with a dry cloth or sandpaper. If they have exceeded their service life, the spark plugs need to be replaced.

Is the Sagitar very noisy?

How to Determine the Depth of Car Paint Scratches?

Depending on the condition of the car, this process usually takes only 30 to 40 minutes. With the naked eye, white cars typically have black or gray primer, while dark-colored cars show the opposite. Below is some information about vehicle painting: 1. Causes: Rainwater generally contains acidity, and acid rain can significantly damage car paint, leading to oxidation of the paint surface and loss of gloss. 2. Consequences: After rain, the increased humidity affects the drying speed of freshly painted surfaces, but the moisture also reduces dust in the air, which is beneficial for painting. 3. Precautions: (1) If the car has just been painted, avoid exposing the newly painted areas to water and dust; (2) It's best not to drive the car out on rainy days, as the fresh paint is still delicate and can be marked by rainwater, leaving unsightly traces that may not be removable even with polishing. Parking in a garage at night is recommended; (3) Sunlight is not a concern—it only speeds up the drying process and is beneficial; (4) Avoid exposing the newly painted areas to chemicals and oil stains.

What are the usage and precautions for seat belts?

1. Regularly inspect the seat belt to check if it is malfunctioning: When slowly pulling the seat belt downward by hand, it should smoothly extend from the retractor. If you pull the seat belt abruptly, it should not move. 2. Wear the seat belt correctly: The three-point lap belt should be worn as low as possible, positioned across the hips, not the waist; the shoulder belt should not be placed under the arm but should cross the chest diagonally. Seat belts are for individual use only and should not be twisted. 3. Do not remove or install seat belts arbitrarily: If a seat belt has been subjected to a strong stretching load during use, it should be replaced even if it appears undamaged and should not continue to be used. 4. Clean the seat belt with great care: When the seat belt is dirty, use mild soap and water as a cleaning solution, and scrub with a cloth or sponge. Avoid using dyes and bleach.
