Asked by for the 2007 Chevrolet Equinox
it is an indication that the abs is not functioning. take and have it checked so that you will not loose your brakes completely.

My 2007 equinox has the same warning, the brake fluid level was low. I refilled it three times, working with the dealer on finding the leak. please post your resolve.
