MAINTENANCE SCHEDULE — 6.2L SUPERCHARGED AND 6.4L
The Scheduled Maintenance services listed in this manual must be done at the times or
mileages specified to protect your vehicle warranty and ensure the best vehicle perfor-
mance and reliability. More frequent maintenance may be needed for vehicles in severe
operating conditions, such as dusty areas and very short trip driving. Inspection and
service should also be done anytime a malfunction is suspected.
The oil change indicator system will remind you that it is time to take your vehicle in for
scheduled maintenance.
The message “Oil Change Required” will be displayed in the DID and a single chime will
sound, indicating that an oil change is necessary.
Based on engine operation conditions, the oil change indicator message will illuminate.
This means that service is required for your vehicle. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).
NOTE:
