Heavy Duty Use Of Vehicle
Change the engine oil and engine oil filter at
every 4,500 miles (7,500 km) or 12 months
if using your vehicle under any of the
following severe duty conditions:
Stop and go driving.
Driving in dusty conditions.
Short trips of less than 10 miles (16 km).
Trailer towing.
Taxi, police, or delivery service (commer -
cial service).
Off-road or desert operation.
Scheduled Servicing — Diesel Engine
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 engine oil
replacement.
Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely
hot or cold ambient temperatures will influ -
ence when the “Oil Change Required”
message is displayed. Severe Operating
Conditions can cause the change oil
message to illuminate as earlier than speci -
fied. Have your vehicle serviced as soon as
possible, within the next 500 miles
(805 km).
To help you have the best driving experience
possible, the manufacturer has identified the
specific vehicle maintenance service inter -
vals that are required to keep your vehicle
operating properly and safely. The manufacturer recommends that these
maintenance intervals be performed at your
selling dealer. The technicians at your deal
-
ership know your vehicle best, and have
access to factory trained information,
genuine Mopar parts, and specially designed
electronic and mechanical tools that can
help prevent future costly repairs.
NOTE:
The actual interval for changing engine oil
and replacing the engine oil filter depends
on the vehicle usage conditions, and is
signaled by the warning light or message in
the instrument panel. In any case, it must
never exceed 12,500 miles (20,000 km) or
12 months.
Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)
whichever comes first.
The timing and accessory belts must be
changed every 37,500 miles (60,000 km) or
3 years for particularly demanding use
(dusty areas, severe weather conditions,
very low or very high temperatures for
extended periods, city driving, long periods
of idling). Under no circumstances should
these intervals be exceeded.

Once A Month Or Before A Long Trip
Check engine oil level.
Check windshield washer fluid level.
Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.
Check the fluid levels of the coolant reser-
voir and brake master cylinder, fill as
needed.
Check function of all interior and exterior
lights.
Control and recovery of additive level for
AdBlue® Diesel emissions (UREA) (if
equipped) At Each Oil Change
Change the engine oil filter.
Inspect the brake hoses and lines.
Inspect for the presence of water in the
fuel filter/water separator unit.
Inspect the CV/Universal joints.
Demanding Vehicle Use
Restore additive level for AdBlue® Diesel
emissions (UREA) (if equipped), when the
lamp is illuminated or the message on the
instrument panel.
