STARTING AND DRIVING CAUTION When the tires whose ID code is registered at "MAIN" are used, the system does not work properly with the selector switch set at "2nd". If the tires whose ID code is registered at "2nd" are stored nearby, the system will detect their tire pressure (and vice versa). TYPES OF TIRES Determine what kind of tires your vehicle is originally equipped with. 1. Summer tires Summer tires are high-speed capability tires best suited to highway driving under dry conditions. Since summer tires do not have the same traction performance as snow tires, summer tires are inadequate for driving on snow-covered or icy roads. For driving on snow-covered or icy roads, we recommend using snow tires. If installing snow tires, be sure to replace all four tires. Liquid sealants for flat tires NOTICE Do not use liquid sealants for flat tires as the air pressure sensors will be damaged. 2. All season tires All season tires are designed to provide better traction in snow and to be adequate for driving in most winter conditions, as well as for use all year round. All season tires, however, do not have adequate traction performance compared with snow tires in heavy or loose snow. Also, all season tires fall short in acceleration and handling performance compared with summer tires in highway driving. 225
