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, extremely hot or cold ambient
temperatures, and E85 fuel usage 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.
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 the tire pressure and look for unusual
wear or damage
Check the fluid levels of the coolant reservoir,
brake master cylinder and fill as needed
Check function of all interior and exterior lights

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 competent 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.

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 instrument cluster display will indicate when
the washer fluid level is low. When the sensor
detects a low fluid level, the Low Washer Fluid
Warning Light will illuminate and the "Washer Fluid
Low" message will display.
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 solution or mixture that meets or
exceeds the temperature range of your climate.
This rating information can be found on most
washer fluid containers.MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a maintenance-free
battery. Water will never have to be added, and
periodic maintenance is not required.
CAUTION!
Overfilling or underfilling the crankcase will
cause 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.
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 Ú page 246. If acid
splashes in eyes or on skin, flush the area
immediately with large amounts of water.
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.

PRESSURE WASHING
Cleaning the engine compartment with a high
pressure washer is not recommended.
VEHICLE MAINTENANCE
An authorized dealer has the qualified service
personnel, special tools, and equipment to
perform all service operations in an expert
manner. Service Manuals are available which
include detailed service information for your
vehicle. Refer to these Service Manuals before
attempting any procedure yourself.
NOTE:Intentional tampering with emissions control
systems may void your warranty and could result in
civil penalties being assessed against you.
ENGINE OIL
Engine Oil Selection
Use only the manufacturer's recommended fluid
Úpage 312.
NOTE:Hemi engines at times can tick right after startup
and then quiet down after approximately 30
seconds. This is normal and will not harm the
engine. This characteristic can be caused by short
drive cycles. For example, if the vehicle is started
then shut off after driving a short distance. Upon
restarting, you may experience a ticking sound.
Other causes could be if the vehicle is unused for
an extended period of time, incorrect oil, extended
oil changes or extended idling. If the engine
continues to tick or if the Malfunction Indicator
Battery posts, terminals, and related accesso -
ries contain 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.
WARNING!
CAUTION!
Precautions have been taken to safeguard all
parts and connections however, the pressures
generated by these machines is such that
complete protection against water ingress
cannot be guaranteed.
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.
