These steps are necessary to allow the brake system pressure relief procedure to occur. Failure to follow these steps may result in warning lamps and/or DTC-s being set pertaining to interruption of the pressure relief procedure. Other vehicle systems may also be affected by not allowing a one minute duration for vehicle power down.

To disconnect the negative battery cable, proceed as follows. Turn off all lamps and accessories. Turn the ignition OFF without pausing at ACC, remove the ignition key. Wait at least one minute before disconnecting the negative battery cable from the battery. Reposition the negative battery cable cover from the terminal. Rotate the lock lever counterclockwise in order to disconnect the cable from the battery.
