Selecting the Right Schedule

First you will need to decide which of the two schedules is right for your vehicle. Here is how to decide which schedule to follow:

Short Trip/City Deﬁnition

Follow the Short Trip/City Scheduled Maintenance if any one of these conditions is true for your vehicle:

•Most trips are less than 5 miles (8 km). This is particularly important when outside temperatures are below freezing.

•Most trips include extensive idling (such as frequent driving in stop-and-go traffic).

•You frequently tow a trailer or use a carrier on top of your vehicle.

•If the vehicle is used for delivery service, police, taxi or other commercial application.

One of the reasons you should follow this schedule if you operate your vehicle under any of these conditions is that these conditions cause engine oil to break down sooner.

Short Trip/City Intervals

Every 3,000 Miles (5 000 km): Engine Oil and Filter Change (or 3 months, whichever occurs ﬁrst). Chassis Lubrication (or 3 months, whichever occurs ﬁrst). Drive Axle Service.

Every 6,000 Miles (10 000 km): Tire Rotation.

Every 15,000 Miles (25 000 km): Engine Air Cleaner Filter Inspection. Automatic Transmission Service (severe conditions only).
