Follow the Short Trip/City Maintenance Schedule if any one of these conditions is true for your vehicle: Most trips are less than 5 to 10 miles (8 to 16 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). Most trips are through dusty areas. 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.
