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.
