OPERATING TIPS
Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected with
a high-quality antifreeze coolant to provide proper
corrosion protection and to protect against engine
overheating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling
system is functioning properly and the proper
amount, type, and concentration of coolant is
used. Use of the Air Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Ú page 461.
Window Fogging
Vehicle windows tend to fog on the inside in mild,
rainy, and/or humid weather. To clear the
windows, select Defrost or Mix mode and increase
the front blower speed. Do not use the
Recirculation mode without A/C for long periods,
as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of
the windshield, is free of obstructions, such as
leaves. Leaves collected in the air intake may
reduce airflow, and if they enter the air distribution
box, they could plug the water drains. In Winter
months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized dealer to
service your cabin air filter, and to have it replaced
when needed.
Stop/Start System — If Equipped
While in an Autostop, the Climate Control system
may automatically adjust airflow to maintain cabin
comfort. Customer settings will be maintained
upon return to an engine running condition.

ESSAGES
This engine meets all required diesel engine
emissions standards. To achieve these emissions
standards, your vehicle is equipped with a
state-of-the-art engine and exhaust system. These
systems are seamlessly integrated into your
vehicle and managed by the Powertrain Control
Module (PCM). The PCM manages engine
combustion to allow the exhaust system’s catalyst
to trap and burn Particulate Matter (PM)
pollutants, with no input or interaction on your part. Your vehicle has the ability to alert you to
additional maintenance required on your vehicle or
engine. Refer to the following messages that may
be displayed on your instrument cluster:
Exhaust Filter XX% Full Safely Drive at Highway
Speeds to Remedy
— This message will be
displayed in the instrument cluster if the
exhaust particulate filter reaches 80% of its
maximum storage capacity. Under conditions of
exclusive short duration and low speed driving
cycles, your diesel engine and exhaust
after-treatment system may never reach the
conditions required to cleanse the filter to
remove the trapped PM. If this occurs, the
“Exhaust Filter XX% Full Safely Drive at Highway
Speeds to Remedy” message will be displayed
in the instrument cluster display. If this
message is displayed, you will hear one chime
to assist in alerting you of this condition. By
simply driving your vehicle at highway speeds
for up to 20 minutes, you can remedy the condi -tion in the particulate filter system and allow
your diesel engine and exhaust after-treatment
system to cleanse the filter to remove the
trapped PM and restore the system to normal
operating condition.
Exhaust System — Regeneration In Process
Exhaust Filter XX% Full
— This message indi-
cates that the DPF is self-cleaning. Maintain
your current driving condition until regeneration
is completed.
Exhaust System — Regeneration Completed —
This message indicates that the DPF
self-cleaning is completed. If this message is
displayed, you will hear one chime to assist in
alerting you of this condition.
Exhaust Service Required — See Dealer Now —
This messages indicates regeneration has been
disabled due to a system malfunction. At this
point the engine Powertrain Control Module
(PCM) will register a fault code, the instrument
panel will display a MIL light.
WARNING!

A hot exhaust system can start a fire if you park
over materials that can burn, such as grass or
leaves, and those items that come into contact
with your exhaust system. Do not park or operate
your vehicle in areas where your exhaust system
can contact anything that can burn.

CAUTION!
See an authorized dealer, as damage to the
exhaust system could occur soon with continued
operation.

22_DT_OM_EN_USC_t.book Page 124

GETTING TO KNOW YOUR INSTRUMENT PANEL125
Exhaust Filter Full — Power Reduced See
Dealer — This message indicates the PCM has
derated the engine to limit the likelihood of
permanent damage to the after-treatment
system. If this condition is not corrected and a
dealer service is not performed, extensive
exhaust after-treatment damage can occur. To
correct this condition it will be necessary to have
your vehicle serviced by an authorized dealer.
NOTE:Failing to follow the oil change indicator, changing
your oil and resetting the oil change indicator by
0 miles remaining will prevent the diesel exhaust
filter from performing it's cleaning routine. This will
shortly result in a Malfunction Indicator Light (MIL)
and reduced engine power. Only an authorized
dealer will be able to correct this condition.
