4-3. Do-it-yourself maintenance l When operating the tire pressure warning reset switch, the warning light does not flash and the setting message does not appear on the multi-information display. l After driving for a certain period of time since the initialization has been com- pleted, the warning light flashes. n When the tire pressure warning valves and transmitter are removed from the wheel on occasions such as when replacing tires The tire inflation pressure data updated before servicing is retained. n Routine tire inflation pressure checks The tire pressure warning system does not replace routine tire inflation pressure checks. Make sure to check tire inflation pressure as part of your routine of daily vehicle checks. n Maximum load of tire Check that the maximum load of the replaced tire is greater than 1/2 of the Gross Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever is greater. As for the maximum load of the tire, see the load limit at maximum cold tire inflation pressure mentioned on the sidewall of the tire, and as for the Gross Axle Weight Ratings (GAWR), see the Certification Label. (→P. 519, 619). n Tire types 4 Maintenance and care 1 Summer tires Summer tires are high-speed performance 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 roads or icy roads, the use of snow tires is recommended. When installing snow tires, be sure to replace all four tires. 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 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. 515
