The 2005 Chevrolet Malibu’s clock time doesn’t automatically adjust when you enter another time zone, nor does it automatically adjust for DST (Daylight Savings Time).
For these reasons, you may need to change the clock’s time every now and then. The clock may also require re-setting after the car’s battery is replaced. You can set the 2005 Chevy Malibu’s clock using the radio buttons.
Push the “Clock” button in the bottom-right corner of the Malibu’s radio. The clock’s hour digit will start to flash.
