Tire Inflation Check

Inspect your vehicle's tires and make sure they are inflated to the correct pressures. Do not forget to check your spare tire. See "Inflation - Tire Pressure" in your owner manual. Check to make sure the spare tire is stored securely. See "Changing a Flat Tire" in your owner manual.

Tire Wear Inspection

Tire rotation may be required for high mileage highway drivers prior to the Engine Oil Life System service notification. Check the tires for wear and, if necessary, rotate the tires. See "Tire Inspection and Rotation" in your owner manual.
