Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured or killed if you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position without first fully engaging the parking
brake. The transfer case NEUTRAL (N) position disengages both the front and rear
driveshafts from the powertrain and will allow the vehicle to move, even if the
transmission is in PARK. The parking brake should always be applied when the
driver is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain that the transfer case is fully in
NEUTRAL (N) before recreational towing to prevent damage to internal parts.
Use the following procedure to prepare your vehicle for recreational towing:
1. Bring the vehicle to a complete stop, with the engine running.
2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL.
4. If vehicle is equipped with Quadra-Lift air suspension, ensure the vehicle is set to Normal Ride Height.
5. Using a ballpoint pen or similar object, press and hold the recessed transfer case NEUTRAL (N) button (located by the selector switch) for four seconds. The light
behind the N symbol will blink, indicating shift in progress. The light will stop
blinking (stay on solid) when the shift to NEUTRAL (N) is complete. A “FOUR
WHEEL DRIVE SYSTEM IN NEUTRAL” message will display on the Driver
Information Display (DID).
6. After the shift is completed and the NEUTRAL (N) light stays on, release the NEUTRAL (N) button.
7. Shift the transmission into REVERSE.
8. Release the brake pedal for five seconds and ensure that there is no vehicle movement.

CAUTION!
• Diesel fuel will damage blacktop paving surfaces. Drain the filter into anappropriate container.
• Do not prefill the fuel filter when installing a new fuel filter. There is a
possibility debris could be introduced into the fuel filter during this action. It
is best to install the filter dry and allow the in-tank lift pump to prime the fuel
system.
• If the “Water In Fuel Indicator Light” remains on, DO NOT START the engine
before you drain water from the fuel filter to avoid engine damage.
EXHAUST REGENERATION
This engine meets all required EPA 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). Additionally, 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 Driver Information
Display (DID).
Exhaust System — Regeneration Required Now
This message Indicates that the Diesel Particulate Filter (DPF) reached 80% of its
maximum storage capacity.
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 Exhaust Filter XX% Full
Indicates that the Diesel Particulate Filter (DPF) is self-cleaning. Maintain your
current driving condition until regeneration is completed.
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 alerting
you of this condition.

Exhaust Service Required — See Dealer Now
This message indicates regeneration has been disabled due to a system malfunction.
The Powertrain control Module (PCM) will register a fault code and the instrument
panel will display the Malfunction Indicator Light (MIL).
CAUTION!
See your authorized dealer, as damage to the exhaust system could occur soon
with continued operation.
Exhaust Filter Full — Power Reduced See Dealer
The PCM derates the engine in order 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. Have your
vehicle 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 reduced engine power. Only an authorized dealer will be able to
correct this condition.
CAUTION!
See your authorized dealer, as damage to the exhaust system could occur with the
exhaust filter full.
DIESEL EXHAUST FLUID
Diesel Exhaust Fluid (DEF) sometimes known simply by the name of its active
component, UREA – is a key component of selective catalytic reduction (SCR)
systems, which help diesel vehicles meet stringent emission regulations. DEF is a
liquid reducing agent that reacts with engine exhaust in the presence of a catalyst to
convert smog-forming nitrogen oxides (NOx) into harmless nitrogen and water vapor.
Your vehicle is equipped with a Selective Catalytic Reduction system in order to meet
the very stringent diesel emissions standards required by the Environmental Protec-
tion Agency. Selective Catalytic Reduction (SCR) is the first and only technology in
decades to be as good for the environment as it is good for business and vehicle
performance.
DIESEL

Adding Diesel Exhaust Fluid
The DEF gauge (located in the DID) will display the level of DEF remaining in the
tank.
Completely fill the DEF tank through the diesel exhaust fluid fill location (located
behind the fuel door) at every maintenance interval or before if prompted by the
Driver Information Display (DID).
NOTE:
• The gauge may take up to five seconds to update after adding a gallon or more ofDiesel Exhaust Fluid (DEF) to the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See your authorized dealer for
service.
• The DEF gauge may also not immediately update after a refill if the temperature of the DEF fluid is below 12F (-11C). The DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update after a period of run time. Under very cold
conditions, it is possible that the gauge may not reflect the new fill level for several
drives.
NOTE:
• Driving conditions (altitude, vehicle speed, load, etc.) will effect the
amount of DEF that is used in your
vehicle.
• Since DEF will begin to freeze at 12°F (-11°C), your vehicle is equipped with
an automatic DEF heating system.
This allows the DEF injection system to
operate properly at temperatures be-
low 12°F (-11°C).
