Using Electrolyte Specific Gravity Method [Without i-ELOOP]

WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.

Remove the battery filler caps and check the water level.
- If necessary, add water to the appropriate level.
Measure the electrolyte specific gravity using a hydrometer.
- If it is less than the specification, recharge the battery. (See BATTERY RECHARGING [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
