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 ve-
hicle could result in a component malfunction and
effect vehicle handling and performance. This
could cause an accident.
Additional Maintenance — B6 To B20 Biodiesel
NOTE:
• Under no circumstances should oil change intervals
exceed 8,000 miles (12 875 km) or six months, which-
ever 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 indicator system
does not reflect the use of biofuels.

200 miles (322 km) of the fault being detected.
When the DEF system needs to be serviced the following
warnings will display:
•Service DEF System See Dealer — This message will
display when the fault is initially detected, each time
the vehicle is started, and periodically during driving.
The message will be accompanied by a single chime.
We recommend you drive to your nearest authorized
dealer and have your vehicle serviced as soon as
possible.
• 5 MPH Max Speed in 150 mi Service DEF System See
Dealer — This message will display if the DEF system
has not been serviced after the “Service DEF System –
See Dealer” message is displayed. This message will
continuously display until the mileage counter reaches
zero, and will be accompanied by a periodic chime.
The message will continue to countdown until it reaches zero unless the vehicle is serviced. We recom-
mend you drive to your nearest authorized dealer and
have your vehicle serviced immediately.
NOTE: Under some circumstances this mileage counter
may start with a value of less than 150 miles (241 km). For
example, if recurring faults are detected in a time interval
of less than 40 hours, the counter may restart at the value
where it stopped when a previous fault was temporarily
remedied, or at a minimum of 50 miles (80 km).
• 5 MPH Max Speed on Restart, Long Idle or Refuel

Diesel Exhaust Fluid (DEF) Warning Messages
Your vehicle will begin displaying warning messages
when the DEF level reaches a driving range of approxi-
mately 500 miles (800 km). If the following warning
message sequence is ignored, your vehicle may not
restart unless DEF is added with in the displayed mileage
shown in the Cluster message.
•Engine Will Not Restart in XXXX mi DEF Low Refill

range is less than 500 miles, DEF fluid top off is required
with in the displayed mileage. The message will be
displayed in the cluster during vehicle start up with the
current allowed mileage and accompanied by a single
chime. The remaining mileage can be pulled up anytime
by way of the “Messages” list within the DID
• Engine Will Not Restart in XXXX mi Refill DEF —
This message will display when DEF driving range is
less than 200 miles. It is also displayed at 150 miles and 100 miles. DEF fluid top off is required with in the
displayed mileage. The message will be displayed in
the DID during vehicle start up with an updated
distance mileage, and it will be accompanied by a
single chime. Starting at 100 miles, remaining range
will be continuously displayed while operating the
vehicle. Chimes will also accompany the 75, 50 and 25
mile remaining distances. The DEF Low telltale will be
on continuously until DEF fluid is topped off.
• Engine Will Not Restart Refill DEF — This message
will display when the DEF driving range is less than 1
mile, DEF fluid top off is required or the engine will
not restart. The message will be displayed in the DID

•Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant (anti-
freeze) needs to be added, the contents of the coolant
expansion bottle must also be protected against freez-
ing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
• Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion
protection of your engine which contains aluminum
components.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean. •
Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased emis-
sions.
Charge Air Cooler — Inter-Cooler
The charge air cooler is positioned below the radiator and
the air conditioner condenser. Air enters the engine
through the air cleaner and passes through the turbo-
charger, where it is pressurized. This pressurized air
rapidly reaches high temperature. The air is then directed
through a hose to the charge air cooler and through
another hose to the intake manifold of the engine. The air
entering the engine has been cooled by about 50° to 100°F
(10° to 38°C). This cooling process enables more efficient
burning of fuel resulting in fewer emissions.
