I Short TriplCity Maintenance Schedule I * If your vehicle has an Engine Oil Life Monitor, the monitor will show you when to change the oil -- usually between 3,000 miles (5 000 km) 7,500 miles and (12 500 km) since your last oil change. Under severe conditions the indicator may come on before 3,000 miles (5 000 km). Never drive your vehicle more than 7,500 miles (12 500 km) or 12 months (whichever occurs first) without an oil change. The system won't detect dustin the oil. So if you drive in a dusty area be sure to change your oil every 3,000 miles (5 000 km) or sooner if the CHANGE OIL light comes on. Remember to reset the Oil Life Monitor when the oil has been changed. For more information, see "Engine Oil Life Monitor'' in the Index. The services shown in this schedule up to 100,000miles (166 000 km) should be performed after 100,000miles (166 000 km) at the same intervals. Footnotes 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 limitrecall 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.
