SOME CUSTOMERS MAY COMPLAIN THAT THE DOORS DO NOT LOCK / UNLOCK WHEN PRESSING THE REQUEST SWITCH. THIS MAY BE CAUSED BY A TORN OR CRACKED REQUEST SWITCH RUBBER BUTTON (A). THE RUBBER SURFACE OF THE REQUEST SWITCH MAY BECOME GRADUALLY WORN OUT BY REPEATED USE. WATER MAY ENTER THE REQUEST SWITCH AND CAUSE A SHORT-CIRCUIT OF THE ELECTRICAL SYSTEM. TO ELIMINATE THIS CONCERN, THE THICKNESS OF THE RUBBER BUTTON HAS BEEN INCREASED FROM 0.6 MM TO 1.8 MM TO IMPROVE WEAR RESISTANCE.
