    2010-2013 Mazda 3 & Skyactiv Audio & Electronics
    I have a 2010 Mazda 3S, 2.5L, 6 speed manual with a stock battery. Last year was the first (Michigan) winter with the car and it was not a fun experience. Long story short, I had trouble starting my car more times than not and that's if it started at all. After a couple trips to the dealer, I...

However, to access that plug in the engine compartment one must remove the battery box. My question is, and...

    I've had my 3 since last August and have never had this problem. Over the last couple days I kept randomly seeing a red flash coming from my cluster. This morning was quite a bit cooler than it has been for about 2 weeks. I hit my brakes for a stoplight and my battery light came on for about 3...

  10. Battery maintenance

    2010-2013 Mazda 3 & Skyactiv Discussion
    I just checked the water level in my battery and it's about 1/4" low from the full line. Do you think it's worth adding distilled water. Wouldn't adding water dilute the acid ratio? Has anyone had to add to their battery yet?

    So I was installing an additional horn today (went swimmingly and sounds awesome btw), and I also just so happen to have a slight fear of putting my hands in small, dark, confined spaces in which there may be electrical arcing or shock risk. The only way I could do it was to blindly put my...
