Maintenance schedule
The following maintenance intervals are based on the assumption that
the vehicle owner will be doing the maintenance or service work, as op-
posed to having a dealer service department do the work. Although the
time/mileage intervals are loosely based on factory recommendations,
most have been shortened to ensure, for example, that such items as lu-
bricants and fluids are checked/changed at intervals that promote maxi-
mum engine/driveline service life. Also, subject to the preference of the
individual owner interested in keeping his or her vehicle in peak condition

at all times, and with the vehicle’s ultimate resale in mind, many of the
maintenance procedures may be performed more often than recom-
mended in the following schedule..We encourage such owner initiative.
When the vehicle is new it should be serviced initially by a factory au-
thorized dealer service department to protect the factory warranty. In
many cases the initial maintenance check is done at no cost to the owner
(check with your dealer service department for more information).
