4-3. Do-it-yourself maintenance

Maintenance and care

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 dis-

play.

After driving for a certain period of time since the initialization has been com-

pleted, the warning light flashes.

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.

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.

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. (

Tire types

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 perfor-

mance 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 ade-

quate for driving in most winter conditions, as well as for use year round. All sea-

son 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.
