#3 ... mine doesnt auto switch air cond to ON every time I start unless I didnit switch the air cond OFF before engine shutdown .. U probably did not switch the air cond off before you switch off the engine . To switch off the air cond , press the blower buttton to reduce the FAN strength to minimum . THEN lift your finger and press it again once to switch it OFF . Then the whole air cond display goes blank. It is OFF now. When u start the engine next(or turn the ignition key to ON) the air cond will be OFF. After engine start , u can just press AUTO or the FAN blower button to start the air cond lah . Hope that helps.
