Scheduled Maintenance
7-5
Short Trip/City Definition
Follow the Short Trip/City Scheduled Maintenance if
any one of these conditions is true for your vehicle:
D Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures are
below freezing.
D Most trips include extensive idling (such as frequent
driving in stop
-
and
-
go traffic).
D You frequently tow a trailer or use a carrier on top of
your vehicle.
D 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.
