What is the reason for the Mazda 6 anti-theft alarm sounding for no reason?

[Max]

Mazda 6 anti-theft alarm sounding for no reason is most likely due to the excessive sensitivity of the alarm. Below is relevant information regarding Mazda maintenance: 1. Check the antifreeze: The amount of antifreeze must be appropriate. Maintenance stations recommend changing the antifreeze every two years, but mixed antifreeze (especially if water has been added in summer) must be replaced annually. Note that products of different brands and models should not be mixed. Next is the engine oil. In winter, the lubrication requirements for the car are higher. If summer-grade oil is being used, it must be replaced. Oil that has been used for a long time, turned black, or has reduced adhesion should be replaced to ensure smooth engine starts. 2. Switch to higher-grade gasoline: If you usually use 90-grade gasoline, you can switch to 93-grade. Because winter driving environments have lower temperatures, higher-grade gasoline has a higher ignition point and slightly better starting capability.
