* The brake fluid change interval is time
based only, mileage intervals do not apply.
** To guarantee correct operation and
prevent serious damage to the engine, it is
essential to proceed as follows: only use

engines; all spark plugs should be of the
same type and brand; strictly comply with
the spark plugs replacement intervals in the
Scheduled Servicing Plan. It is advised to

replacement.
*** Areas that are not dusty: recommended
maximum distance 75,000 mi
(120,000 km). The belt must be replacedevery 6 years, regardless of distance trav

(severe weather conditions, very low or very
high temperatures for extended periods,
urban driving, long periods of idling): the
recommended maximum distance is
37,500 mi (60,000 km). The belt must be
replaced every 4 years, regardless of
distance traveled.
(°) If the vehicle is used in dusty areas, this
air cleaner filter must be replaced every

WARNING!
You can be badly injured working on or
around a motor vehicle. Do only service
work for which you have the knowledge
and the right equipment. If you have any
doubt about your ability to perform a
service job, take your vehicle to a compe-
tent mechanic.
Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an
accident.

Heavy Duty Use Of Vehicle
**** Change the engine oil and engine oil
filter at every 4500 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.
Diesel Engines
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.
The maintenance intervals shown should be
performed as indicated in this section. 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 12,000 miles (20,000km) or 1
year.
Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)
whichever comes first.
Areas that are not dusty: recommended
maximum distance 75,000 mi
(120,000 km). The belt must be replaced
every 6 years, regardless of distance trav-
elled. Dusty areas and/or heavy conditions
(severe weather conditions, very low or very
high temperatures for extended periods,
urban driving, long periods of idling): the
recommended maximum distance is
37,500 mi (60,000 km). The belt must be
replaced every 4 years, regardless of
distance travelled.

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 air cleaner filter if using in dusty
or off-road conditions. Replace air cleaner
filter, if necessary.
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.
Maintenance Plan — Diesel Engines
NOTE:
Once you have carried out the last interven -
tion in the table, continue with the sched -
uled servicing, maintaining the frequency
indicated in the plan by marking each oper -
ation with a dot or dedicated note. Simply
restarting the maintenance from the start of
the plan may cause the allowed interval to be
exceeded for some operations.
CAUTION!
Failure to perform the required
maintenance items may result in damage
to the vehicle.
