SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change indi-
cator system. The oil change indicator system will remind
you that it is time to take your vehicle in for scheduled main -
tenance.
Based on engine operation conditions, the oil change indi -
cator message will illuminate. This means that service is
required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, and extremely hot or cold
ambient temperatures will influence when the “Oil Change
Required” message is displayed. Severe Operating Condi -
tions can cause the change oil message to illuminate as early
as 3,500 miles (5,600 km) since last reset. Have your vehicle
serviced as soon as possible, within the next 500 miles
(805 km).
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 your authorized dealer, the message can be reset by referring
to the steps described under “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel”.
NOTE:
Under no circumstances should oil change intervals exceed
10,000 miles (16,000 km), 12 months or 350 hours of engine
run time, whichever comes first. The 350 hours of engine run
or idle time is generally only a concern for fleet customers.
Severe Duty All Models
NOTE:
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 predominantly at idle, or
only very low engine RPM. This type of vehicle use is consid
-
ered Severe Duty.

The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance. Refer
to the “Maintenance Plan” for further information.
NOTE:
Under no circumstances should oil change intervals exceed
10,000 miles (16,000 km), 12 months or 350 hours of engine
run time, whichever comes first. The 350 hours of engine run
or idle time is generally only a concern for fleet customers.
Gasoline Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only recom -
mends engine oils that are API Certified and meet the
requirements of FCA Material Standard MS-6395.

vehicle. Only do service work for which you have the
knowledge and the proper equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.

Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be replaced.Tire Tread These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes a 1/16 of an inch (1.6 mm). When the tread is worn
to the tread wear indicators, the tire should be replaced.
Refer to “Replacement Tires” in this section for further infor
-
mation.
Life Of Tire
The service life of a tire is dependent upon varying factors
including, but not limited to:
• Driving style
• Tire pressure - Improper cold tire inflation pressures can cause uneven wear patterns to develop across the tire
tread. These abnormal wear patterns will reduce tread life,
resulting in the need for earlier tire replacement
• Distance driven
• Performance tires, tires with a speed rating of V or higher, and Summer tires typically have a reduced tread life. Rota -
tion of these tires per the vehicle scheduled maintenance is
highly recommended
