SERVICING AND MAINTENANCE
SCHEDULED SERVICING — GASOLINE
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 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, and extremely hot or cold ambient
temperatures will influence when the “Oil Change
Required” message is displayed. 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, the
message can be reset by referring to the steps
described under Instrument Cluster Display
Ú
page 114.
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. 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 irreg
-
ular wear, even if it occurs before the oil indi -
cator system turns on.
Check the fluid levels of the coolant reservoir,
brake master cylinder, and fill as needed.
Check function of all interior and exterior lights.

SERVICING AND MAINTENANCE407
CHECKING OIL LEVEL
To ensure proper engine lubrication, the engine oil
must be maintained at the correct level. Check the
oil level at regular intervals, such as every fuel
stop. The best time to check the engine oil level is
about five minutes after a fully warmed up engine
is shut off.
Checking the oil while the vehicle is on level ground
will improve the accuracy of the oil level readings.
There are four possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the low
end of the range and MAX at the high end of the
range.
Crosshatched zone marked with dimples at the
MIN and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 quart (1.0 liter) of oil when the reading is
at the low end of the dipstick range will raise the oil
level to the high end of the range marking.
ADDING WASHER FLUID
The fluid reservoir is located under the hood and
should be checked for fluid level at regular
intervals. Fill the reservoir with windshield washer
solvent only (not radiator antifreeze). When
refilling the washer fluid reservoir, take some
washer fluid and apply it to a cloth or towel and
wipe the wiper blades clean. This will help blade
performance.
To prevent freeze-up of your windshield washer
system in cold weather, select a solution or mixture
that meets or exceeds the temperature range of
your climate. This rating information can be found
on most washer fluid containers. After the engine has warmed up, operate the
defroster for a few minutes to reduce the
possibility of smearing or freezing the fluid on the
cold windshield. Windshield washer solution used
with water as directed on the container, aids
cleaning action, reduces the freezing point to avoid
line clogging, and is not harmful to paint or trim.
CAUTION!
Overfilling or underfilling the crankcase will
cause oil aeration or loss of oil pressure. This
could damage your engine.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling or
working around the washer solution.

ACCESSORY DRIVE BELT INSPECTION
When inspecting accessory drive belts, small
cracks that run across the ribbed surface of the
belt from rib to rib, are considered normal. This is
not a reason to replace the belt. However, cracks
running along a rib (not across) are not normal. Any
belt with cracks running along a rib must be
replaced. Also have the belt replaced if it has
excessive wear, frayed cords or severe glazing.
Accessory Belt (Serpentine Belt)
Conditions that would require replacement:
Rib chunking (one or more ribs has separated
from belt body)
Rib or belt wear
Longitudinal belt cracking (cracks between two
ribs)
Belt slips
“Groove jumping" (belt does not maintain
correct position on pulley)
Belt broken
Noise (objectionable squeal, squeak, or rumble
is heard or felt while drive belt is in operation)
NOTE:Identify and correct problem before new belt is
installed.
NOTE:If your vehicle is equipped with a Stop/Start, belt
must be replaced with an OEM grade Mopar® belt.
Some conditions can be caused by a faulty
component such as a belt pulley. Belt pulleys
should be carefully inspected for damage and
proper alignment.
Belt replacement on some models requires the
use of special tools, we recommend having your
vehicle serviced at an authorized dealer.
BODY LUBRICATION
Locks and all body pivot points, including such
items as seat tracks, door hinge pivot points and
rollers, liftgate, tailgate, decklid, sliding doors and
hood hinges, should be lubricated periodically. Use
a lithium-based grease, such as Mopar® Spray
White Lube to assure quiet, easy operation and to
protect against rust and wear. Prior to the
application of any lubricant, the parts concerned
should be wiped clean to remove dust and grit;
after lubricating excess oil and grease should be
removed. Particular attention should also be given
to hood latching components to ensure proper
function. When performing other underhood
services, the hood latch release mechanism, and
safety catch should be cleaned and lubricated.
WARNING!
Do not attempt to inspect an accessory drive
belt with vehicle running.
When working near the radiator cooling fan,
disconnect the fan motor lead. The fan is
temperature controlled and can start at any
time regardless of ignition mode. You could be
injured by the moving fan blades.
You can be badly injured working on or around
a motor vehicle. Only do service work for which
you have the knowledge and the proper equip -
ment. If you have any doubt about your ability
to perform a service job, take your vehicle to a
competent mechanic.

(Continued)
To guarantee optimum performance of the system,
keep the surfaces of the charge air cooler,
condenser and radiator clean and free of debris.
Periodically check the hoses leading to and from
the charge air cooler for cracks or loose clamps
resulting in loss of pressure and reduced engine
performance.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically Ú
page 394.
Fluid Level Check — Brake Master Cylinder
The fluid level of the brake master cylinder should
be checked whenever the vehicle is serviced, or
immediately if the Brake System Warning Light is
on. If necessary, add fluid to bring level within the
designated marks on the side of the reservoir of
the brake master cylinder. Be sure to clean the top
of the master cylinder area before removing cap.
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. If the brake fluid
is abnormally low, check the system for leaks
Úpage 476.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in
abnormally high brake temperatures, excessive
lining wear, and possible brake damage. You
would not have your full braking capacity in an
emergency.WARNING!
Use only manufacturer's recommended brake
fluid Ú page 476. 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 reservoir.
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 reservoir 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 contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
WARNING!

TECHNICAL SPECIFICATIONS471
Biodiesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient
temperatures, which may pose problems for both
storage and operation. Precautions can be
necessary at low ambient temperatures, such as
storing the fuel in a heated building or a heated
storage tank, or using cold temperature additives.
Fuel Quality — Must Comply With ASTM
Standards
The quality of Biodiesel fuel may vary widely. Only
fuel produced by a BQ9000 supplier to the
following specifications may be blended to meet
Biodiesel blend B6 – B20 fuel meeting ASTM
specification D-7467: Petrodiesel fuel meeting ASTM specification D-975
and Biodiesel fuel (B100) meeting ASTM
specification D-6751
Fuel Oxidation Stability — Must Use Fuel
Within Six Months Of Manufacture
Biodiesel fuel has poor oxidation stability which
can result in long term storage problems. Fuel
produced to approved ASTM standards, if stored
properly, provides for protection against fuel
oxidation for up to six months.
Fuel Water Separation — Must Use
Mopar® Approved Fuel Filter Elements
Biodiesel fuel has a natural affinity to water and
water accelerates microbial growth. Your Mopar®
filtration system is designed to provide adequate
fuel water separation capabilities.
Fuel In Oil Dilution — Must Adhere To
Required Oil Change Interval
Fuel dilution of lubricating oil has been observed
with the use of Biodiesel fuel. Fuel in oil must not
exceed 5%. To ensure this limit is met your oil
change interval must be maintained with in the
suggested schedule. The regular use of biodiesel
between 6% and 20% requires intervals shorter
than the outlined 10,000 miles (16,100 km) and
must not exceed the suggested schedule. When
routinely operating on biodiesel between 6% and
20%, oil and filter replacement intervals must not
exceed 8,000 Miles (12,900 km) or six months,
which ever comes first.
Biodiesel Fuel Filter Change Intervals
The use of biodiesel requires more frequent fuel
filter change intervals. When operating on
biodiesel between 6% and 20%, fuel filter
replacement intervals should be every second oil
change, and must not exceed 16,000 miles
(25,750 km).
NOTE:Under no circumstances should oil change
intervals exceed 8,000 miles (12,875 km) or six
months, if regular operation occurs with 6% - 20%
biodiesel blends. Under no circumstances should
fuel filter replacement intervals exceed every
second oil change and must not exceed
16,000 miles (25,750 km), if regular operation
occurs with 6% - 20% biodiesel blends. Failure to
comply with these oil change and fuel filter require
-
ments for vehicles operating on biodiesel blends
up to B20 may result in premature engine wear.
Such wear is not covered by the New Vehicle
Limited Warranty. The engine may suffer severe
damage if operated with concentrations of
biodiesel higher than 20%.
CAUTION!
In the event that the vehicle is filled with
biodiesel and not used for more than a month,
the fuel should either be used up by driving (up
to quarter tank) and filled with standard diesel
blends with less than 5% that is normally
available. This will help prevent the fuel filter
clogging and potential damage to the fuel
injection system due to degraded biodiesel,
which is not covered by the New Vehicle Limited
Warranty.
