SCHEDULED SERVICING
The Scheduled Maintenance services listed in this manual
must be done at the times or mileages specified to protect
your vehicle warranty and ensure the best vehicle perfor-
mance and reliability. More frequent maintenance may be
needed for vehicles in severe operating conditions, such as
dusty areas and very short trip driving. Inspection and
service should also be done anytime a malfunction is
suspected.
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
The instrument cluster display will display an “Oil Change
Required” message and a single chime will sound, indicat-
ing that an oil change is necessary.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Have your vehicle serviced as
soon as possible, within the next 500 miles (800 km).NOTE:
•
The oil change indicator message will not monitor the
time since the last oil change. Change your vehicle’s oil
if it has been six months since your last oil change, even
if the oil change indicator message is NOT illuminated.
• Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
• Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or six months, whichever
comes first.
Your 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” for
further information.
At Each Stop For Fuel
• Check the engine oil level. Refer to “Engine Compart-
ment” in this section for further information.
• Check the windshield washer solvent and add if re-
quired.

Checking Oil Level
To assure proper lubrication of your vehicle’s engine, 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. Always
maintain the oil level within the SAFE zone on the dipstick.
Adding one quart of oil when the reading is at the bottom
of the SAFE zone will result in a reading at the top of the
safe zone on these engines.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
Adding Washer Fluid
The instrument cluster display will indicate when the
washer fluid level is low. When the sensor detects a low
fluid level, the windshield will light on the vehicle graphic
outline and the “WASHER FLUID LOW” message will be
displayed.The fluid reservoir for the windshield washers and the rear
window washer is shared. The fluid reservoir is located in
the engine compartment, be sure to check the 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 clean the wiper blades, this
will help blade performance. To prevent freeze-up of your
windshield washer system in cold weather, select a solu-
tion or mixture that meets or exceeds the temperature
range of your climate. This rating information can be found
on most washer fluid containers.
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.

Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic mainte-
nance required.
WARNING!
•Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery fluid to
contact your eyes, skin, or clothing. Do not lean over
a battery when attaching clamps. If acid splashes in
eyes or on skin, flush the area immediately with
large amounts of water. Refer to “Jump Starting
Procedure” in “In Case Of Emergency” for further
information.
• Battery gas is flammable and explosive. Keep flame
or sparks away from the battery. Do not use a booster
battery or any other booster source with an output
greater than 12 Volts. Do not allow cable clamps to
touch each other.
• Battery posts, terminals, and related accessories con-
tain lead and lead compounds. Wash hands after
handling.
CAUTION!
•It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
negative post. Battery posts are marked positive (+)
and negative (-) and are identified on the battery
case. Cable clamps should be tight on the terminal
posts and free of corrosion.
• If a “fast charger” is used while the battery is in the
vehicle, disconnect both vehicle battery cables before
connecting the charger to the battery. Do not use a
“fast charger” to provide starting voltage.
DEALER SERVICE
An authorized dealer has the qualified service personnel,
special tools, and equipment to perform all service opera-
tions in an expert manner. Service Manuals are available
which include detailed service information for your ve-
hicle. Refer to these Service Manuals before attempting any
procedure yourself.
NOTE: Intentional tampering with emissions control sys-
tems may void your warranty and could result in civil
penalties being assessed against you.

WARNING!
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 equipment. If you
have any doubt about your ability to perform a service
job, take your vehicle to a competent mechanic.
Engine Oil
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to “Scheduled Servicing” for further information.
NOTE:Under no circumstances should oil change inter-
vals exceed 6,000 miles (10,000 km) or six months, which-
ever occurs first.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only rec-
ommends full synthetic engine oils that meet the American
Petroleum Institute (API) categories of SN.
The manufacturer recommends the use of Pennzoil Ultra
0W-40 engine or equivalent Mopar oil meeting the FCA
Material Standard MS-12633 for use in all operating tem-
peratures.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to “Engine Compart-
ment” in this section for further information.
CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is not
covered by the New Vehicle Limited Warranty.
