NOTE:
Under no circumstances should oil change inter -
vals exceed 8,000 miles (12,875 km) or six  months, whichever comes first when using 
biodiesel blends greater than 5% (B5).
The owner is required to monitor mileage for 
B6-B20 biodiesel, the automatic oil change indi -
cator system does not reflect the use of 
biofuels.
Fuel filter change interval is maintained at every 
second oil change. This is especially important 
with biodiesel usage.

1. Under normal conditions the diesel fuel filter should be replaced every 20,000 miles (32,000 km) (every other oil change). If the vehicle is being used in severe operating conditions, 
or In certain geographical areas of the country (Pennsylvania, New York, Ohio, Maryland, West Virginia, Arkansas, Oklahoma, Kansas, Iowa, Missouri and Nebraska) due to fuel 
cleanliness issues, it’s recommended to replace the fuel filter every 10,000 miles (16,000 km).

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 malfunc -
tion and effect vehicle handling and perfor -
mance. 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 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.

408SERVICING AND MAINTENANCE  
MAINTENANCE-FREE BATTERY  
Your vehicle is equipped with a maintenance-free 
battery. You will never have to add water, and 
periodic maintenance is not required.
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.
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  Úpage 384.
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 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.
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.
