warms up. The blower will increase in speed
and transition into Auto mode.
Manual Operation Override
This system offers a full complement of
manual override features. The AUTO symbol
in the front ATC display will be turned off
when the system is being used in the manual
mode.
NOTE:
The system will not automatically sense the
presence of fog, mist or ice on the wind-
shield. DEFROST mode must be manually
selected to clear the windshield and side
glass.
Operating Tips
NOTE:
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 pro-
vide proper corrosion protection and to pro-
tect against engine overheating. OAT coolant
(conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and de-
froster 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 Recircula-
tion mode during Winter months is not rec-
ommended, because it may cause window
fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for
about five minutes, in fresh air with the
blower setting on high. This will ensure ad-
equate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
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 plenum, 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 your autho-
rized dealer to service your cabin air filter,
and to have it replaced when needed.

Diesel Particulate Filter (DPF) Messages
This engine meets all required diesel engine
emissions standards. To achieve these emis-
sions standards, your vehicle is equipped
with a state-of-the-art engine and exhaust
system. These systems are seamlessly inte-
grated into your vehicle and managed by theSRT Performance Features Controls

Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the ex-
haust system’s catalyst to trap and burn Par-
ticulate Matter (PM) pollutants, with no input
or interaction on your part.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
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.
Your vehicle has the ability to alert you to
additional maintenance required on your ve-
hicle or engine. Refer to the following mes-
sages that may be displayed on your Instru-
ment Cluster Display:
• Exhaust Filter Nearing Full Safely Drive at
Highway Speeds to Clear — This message
will be displayed on the instrument cluster
display if the exhaust particulate filter
reaches 80% of its maximum storage ca-
pacity. 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 condition
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
Continue Driving — This message indicates
that the Diesel Particulate Filter (DPF) is
self-cleaning. Maintain your current driv-
ing condition until regeneration is com-
pleted. •
Exhaust System — Regeneration Completed
— This message indicates that the Diesel
Particulate Filter (DPF) self-cleaning is
completed. If this message is displayed,
you will hear one chime to assist in alert-
ing you of this condition.
• Exhaust System Service Required - See
Dealer — This messages indicates regen-
eration has been disabled due to a system
malfunction. At this point the engine Pow-
ertrain Control Module (PCM) will register
a fault code, the instrument panel will
display a MIL light.
CAUTION!
See your authorized dealer, as damage to
the exhaust system could occur soon with
continued operation.
• Exhaust Filter Full — Power Reduced See
Dealer — This message indicates the PCM
has derated the engine to limit the likeli-
hood of permanent damage to the after-
treatment system. If this condition is not
corrected and a dealer service is not per-
formed, extensive exhaust after-treatment

damage can occur. To correct this condi-
tion it will be necessary to have your ve-
hicle serviced by your local 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 re-
duced engine power. Only an authorized
dealer will be able to correct this condition.
