SERVICING AND MAINTENANCE
SCHEDULED SERVICING
6.2L AND 6.4L ENGINES
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 performance 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.
An “Oil Change Required” message will be
displayed in the instrument cluster 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:
The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicle's oil if it has been six
months since your last oil change, even if the oil
change indicator message is NOT illuminated.
Change your engine oil more often if you drive
your vehicle off-road/track usage for an
extended period of time.
Under no circumstances should oil change
intervals exceed 6,000 miles (10,000 km) or
six months, whichever comes first.
An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change.
