Negative Battery Cable Disconnection/Connection: Notes

WARNING: This page is about a different car, the 2016 Mazda CX-3. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

Before removing the SRS air bag system-related parts, always disconnect the negative battery cable terminal and wait for 1 min. or more to allow the back-up power supply to deplete its stored power. (See AIR BAG SYSTEM SERVICE WARNINGS [TWO-STEP DEPLOYMENT CONTROL SYSTEM] .) (See AIR BAG SYSTEM SERVICE WARNINGS [STANDARD DEPLOYMENT CONTROL SYSTEM] .)

CAUTION:

With the battery connected and the ignition switched ON, or if servicing is performed for a long period (10 min or more) with the ignition switched off.
