MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the
change oil message to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Severe Duty All Models
Change Engine Oil at 4000 miles (6,500 km) if the vehicle
is operated in a dusty and off road environment. This
type of vehicle use is considered Severe Duty.

SUGGESTIONS FOR OBTAINING SERVICE FOR
YOUR VEHICLE
Prepare For The Appointment
If you are having warranty work done, be sure to have
the right papers with you. Take your warranty folder. All
work to be performed may not be covered by the
warranty. Discuss additional charges with the service
manager. Keep a maintenance log of your vehicle’s
service history. This can often provide a clue to the
current problem.
Prepare A List
Make a written list of your vehicle’s problems or the
specific work you want done. If you’ve had an accident
or work done that is not on your maintenance log, let the
service advisor know.
Be Reasonable With Requests
If you list a number of items and you must have your
vehicle by the end of the day, discuss the situation with
the service advisor and list the items in order of priority.
At many authorized dealers, you may obtain a rental
vehicle at a minimal daily charge. If you need a rental, it
is advisable to make these arrangements when you call
for an appointment.

interested in your satisfaction. We want you to be happy
