SERVICING AND MAINTENANCE
SCHEDULED SERVICING
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 scheduled maintenance.
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, extended engine idle
time, extremely hot or cold ambient
temperatures will influence when the “Oil
Change Required” message is displayed.
Severe Operating Conditions 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 an
authorized dealer, to reset the message
Úpage 46. NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
350 hours of engine run time or 12 months,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Severe Duty All Models
Vehicles that are operated in a dusty and
off-road environment, or predominately at idle
or very low engine RPM are known as Severe
Duty vehicles. It is recommended that you
change Engine Oil at 4,000 miles (6,500 km) or
350 hours of engine run time.
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 reservoir
and brake master cylinder, fill as needed.
Check function of all interior and exterior
lights.
Maintenance Plan
Refer to the maintenance schedule for the
required maintenance intervals. More frequent
maintenance may be needed in severe
conditions, such as dusty areas and very short
trip driving. In some extreme conditions,
additional maintenance not specified in the
maintenance schedule may be required.

(Continued)
Brake Master Cylinder
The fluid in the master cylinder should be
checked when performing under hood services
or immediately if the “Brake Warning Light” is
illuminated.
Be sure to clean the top of the master cylinder
area before removing the cap. If necessary, add
fluid to bring the fluid level up to the
requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. Brake
fluid level should be checked when pads are
replaced. However, low fluid level may be
caused by a leak and a checkup may be
needed. Use only FCA recommended brake fluid
Ú page 261.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission
fluid to ensure optimum transmission
performance and life. Use only FCA specified
transmission fluid Ú page 261. It is important
to maintain the transmission fluid at the correct
level using the recommended fluid.
NOTE:
No chemical flushes should be used in any
transmission; only the approved lubricant
should be used.
WARNING!
Use only FCA recommended brake fluid
Ú page 261. Using the wrong type of brake
fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory
installed hydraulic master cylinder reser -
voir.
To avoid contamination from foreign matter
or moisture, use only new brake fluid or
fluid that has been in a tightly closed
container. Keep the master cylinder reser -
voir cap secured at all times. Brake fluid in
an open container absorbs moisture from
the air resulting in a lower boiling point. This
may cause it to boil unexpectedly during
hard or prolonged braking, resulting in
sudden brake failure. This could result in a
collision.
Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces; care should be taken to
avoid its contact with these surfaces.
Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
WARNING! (Continued)
CAUTION!
Using a transmission fluid other than FCA
recommended fluid may cause deterioration
in transmission shift quality and/or torque
converter shudder Ú page 261.

P (Passenger) — Metric tire sizing is based on
US design standards. P-Metric tires have the
letter “P” molded into the sidewall preceding
the size designation. Example: P215/65R15
95H.
European — Metric tire sizing is based on
European design standards. Tires designed
to this standard have the tire size molded
into the sidewall beginning with the section
width. The letter "P" is absent from this tire
size designation. Example: 215/65R15 96H.
LT (Light Truck) — Metric tire sizing is based
on US design standards. The size designation
for LT-Metric tires is the same as for P-Metric
tires except for the letters “LT” that are
molded into the sidewall preceding the size
designation. Example: LT235/85R16.
Temporary spare tires are designed for
temporary emergency use only. Temporary
high pressure compact spare tires have the
letter “T” or “S” molded into the sidewall
preceding the size designation. Example:

SERVICING AND MAINTENANCE245
(Continued)
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 replace -
ment.
Distance driven.
Performance tires, tires with a speed rating of
V or higher, and Summer tires typically have
a reduced tread life. Rotation of these tires
per the vehicle scheduled maintenance is
highly recommended. NOTE:
Wheel valve stem must be replaced as well
when installing new tires due to wear and tear
in existing tires.
Keep dismounted tires in a cool, dry place with
as little exposure to light as possible. Protect
tires from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance
of many characteristics. They should be
inspected regularly for wear and correct cold
tire inflation pressures. FCA strongly
recommends that you use tires equivalent to
the originals in size, quality and performance
when replacement is needed Ú
page 244.
Refer to the Tire and Loading Information
placard or the Vehicle Certification Label for the
size designation of your tire. The Load Index and
Speed Symbol for your tire will be found on the
original equipment tire sidewall.
For more information relating to the Load Index
and Speed Symbol of a tire Ú page 235.
It is recommended to replace the two front tires
or two rear tires as a pair. Replacing just one tire
can seriously affect your vehicle’s handling. If you ever replace a wheel, make sure that the
wheel’s specifications match those of the
original wheels.
It is recommended you contact an authorized
tire dealer or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can result
in sudden tire failure. You could lose control
and have a collision resulting in serious injury
or death.
WARNING!
Do not use a tire, wheel size, load rating, or
speed rating other than that specified for
your vehicle. Some combinations of unap
-
proved tires and wheels may change
suspension dimensions and performance
characteristics, resulting in changes to
steering, handling, and braking of your
vehicle. This can cause unpredictable
handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire and
wheel sizes with load ratings approved for
your vehicle.
