SERVICING AND MAINTENANCE425
(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.

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.
