Footnotes

[Dagger] The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle's useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded.

# Lubricate the grease fittings in the suspension and steering linkage, the transaxle shift linkage, parking brake cable guides and underbody contact points and linkage.

* If this vehicle is equipped with an Oil Life Indicator. This feature will let you know when to change the oil and filter -- usually between 3,000 miles (5 000 km) and 7,500 miles (12 500 km) since your last oil change. Under severe conditions, the indicator may come on before 3,000 miles (5 000 km). For description and resetting information, refer to Oil Life Indicator.

+ A good time to check your brakes is during tire rotation. Refer to Brake System Inspection.
