298SERVICING AND MAINTENANCE
HEAVY DUTY USE OF THE VEHICLE
Change engine oil at 4,000 miles (6,500 km) or
350 hours of engine run time if the vehicle is
operated in a dusty and off road environment or
is operated predominately at idle or only very
low engine RPM. This type of vehicle use is
considered Severe Duty.
SCHEDULED SERVICING – SRT
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.
The instrument cluster display will display an
“Oil Change Required” message 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 illumi-
nated.
Change your engine oil more often if you drive
your vehicle off-road for an extended period
of time.
Under no circumstances should oil change
intervals exceed 6,000 miles (10,000 km) or
6 months, whichever comes first.
An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change. If a scheduled oil change
is performed by someone other than an
authorized dealer, the message can be reset by
referring to the steps described under
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further
information.
