Maintenance Schedule
Short TripKity Definition
Follow the Short TripKity Maintenance Schedule if any
one
of these conditions is true for your vehicle:
0
0
0
0
0
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.
One of the reasons yo~l should follow this schedule if
you operate your vehicle under any of these conditions
is
that these conditions cause engine oil to break
down soonex
