needed. When reading this section, keep in mind the conditions under
which the vehicle is operated, and adjust the maintenance intervals
accordingly.
The maintenance schedules found in this manual are for vehicles that:
| • | Are driven on reasonable road surfaces within legal driving limits. |
| • | Are driven off-road in the recommended manner. |
| • | Use recommended unleaded fuel. |

Short Trip/City Maintenance Definition
Follow the Short Trip/City Scheduled Maintenance only if any one of
the following conditions is true for this vehicle:
| • | Most trips are less than 8-16 km (5-10 mi). |
| | This is particularly important when the outside temperature is
below freezing. |
| • | Most trips include extensive idling, such as frequent driving
