Scheduled Maintenance

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 to 10 miles (8 to 16 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 operate your vehicle in dusty areas or
-
off road frequently.
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.
