Shifting Procedures
4WD HI To 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the
ON/RUN position or the engine running, shift the transmission into NEUTRAL and
press the “4WD LOW” button once on the transfer case switch. The “4WD LOW”
indicator light in the instrument cluster will begin to flash and remain on solid when
the shift is complete.
4WD LOW To 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the
ON/RUN position or the engine running, shift the transmission into NEUTRAL, and
press the “4WD LOW” button once on the transfer case switch. The “4WD LOW”
indicator light in the instrument cluster will flash and turn off when the shift is
complete.
NOTE:
• If the shift conditions/interlocks are not met, or a transfer case motor temperature
protection exists, a “For 4x4 Low Slow Below 5 mph (8 km/h) Put Trans in N Press
4 Low” message will flash on the Electronic Vehicle Information Center (EVIC).
• Shifting into or out of 4WD LOW is possible with the vehicle completely stopped;
however, difficulty may occur due to the mating clutch teeth not being properly
aligned. Several attempts may be required for clutch teeth alignment and shift
completion to occur. The preferred method is with the vehicle rolling 0 to 3 mph
(0 to 5 km/h). If the vehicle is moving faster than 3 mph (5 km/h), the transfer case
will not allow the shift.

PADDLE SHIFT MODE
Paddle Shift Mode is a driver-interactive transmission feature that offers manual gear
shifting to provide you with more control of the vehicle. Paddle Shift Mode allows you
to maximize engine braking, eliminate undesirable upshifts and downshifts, and
improve overall vehicle performance.
This system can also provide you with more control during passing, city driving, cold
slippery conditions, mountain driving, trailer towing, and many other situations.
Refer to the “Starting And Operating” section of your vehicle’s Owner’s Manual on
the DVD for further details.
Paddle Shift Mode Operation
When the shift lever is in the DRIVE position, the transmission will operate
automatically, shifting between the five available gears. To engage Paddle Shift
Mode, simply tap the shift lever to the right or left (+/-) while in the DRIVE position,
or tap one of the steering wheel-mounted shift paddles (+/-). Tapping (-) to enter
Paddle Shift Mode will downshift the transmission to the next lower gear, while using
(+) to enter Paddle Shift Mode will retain the current gear.
When Paddle Shift mode is active, the current transmission gear is displayed in the
instrument cluster. In Paddle Shift Mode, the transmission will shift up or down when
(+/-) is manually selected by the driver (using the shift lever, or the shift paddles),
unless an engine lugging or overspeed condition would result. It will remain in the
selected gear until another upshift or downshift is chosen, except as described
below:
• Normally, in Paddle Shift Mode, the transmission will automatically shift up when
maximum engine speed is reached. If, however, Paddle Shift Mode is engaged
while in SPORT mode, the transmission will remain in the selected gear even when
maximum engine speed is reached. The transmission will upshift only when
commanded by the driver.
• The transmission will automatically downshift as the vehicle slows (to prevent
engine lugging) and will display the current gear.
• The transmission will automatically downshift to first gear when coming to a stop.
After a stop, the driver should manually upshift (+) the transmission as the vehicle
is accelerated.
• You can start out in first or second gear. Tapping (+) (at a stop) will allow starting
in second gear. Starting out in second gear is helpful in snowy or icy conditions.
• If a requested downshift would cause the engine to over-speed, that shift will not
occur.
• The system will ignore attempts to upshift at too low of a vehicle speed.

• Avoid using speed control when Paddle Shift mode is engaged.
• Transmission shifting will be more noticeable when Paddle Shift Mode is engaged.
• To disengage Paddle Shift Mode, hold the shift lever to the right or press and hold
the (+) shift paddle until “D” is once again displayed in the instrument cluster. You
can shift in or out of the Paddle Shift Mode at any time without taking your foot off
the accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a slippery surface. The drive
wheels could lose their grip and the vehicle could skid, causing a collision or
personal injury.

CAUTION!
• Diesel fuel will damage blacktop paving surfaces. Drain the filter into an
appropriate 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 Electronic Vehicle
Information Center (EVIC).
Perform Service
Your vehicle will require emissions maintenance at a set interval. To help remind you
when this maintenance is due, the Electronic Vehicle Information Center (EVIC) will
display “Perform Service”.
When the “Perform Service” message is displayed on the EVIC it is necessary to have
the emissions maintenance performed.

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.
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.
The purpose of the SCR system is to reduce levels of NOx (oxides of nitrogen emitted
from engines) that are harmful to our health and the environment to an almost
near-zero level. Small quantities of Diesel Exhaust Fluid (DEF) are injected into the
exhaust upstream of a catalyst where, when vaporized, convert smog-forming
nitrogen oxides (NOx) into harmless nitrogen (N2) and water vapor (H2O), two
natural components of the air we breathe. You can operate with the comfort that your
vehicle is contributing to a cleaner, healthier world environment for this and
generations to come.
DIESEL

System Overview
This vehicle is equipped with a Diesel Exhaust Fluid (DEF) injection system and a
Selective Catalytic Reduction (SCR) catalyst to meet the emission requirements.
The DEF injection system consists of the following components:
• DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines• NOx sensors
• Temperature sensors
• SCR catalyst
The DEF injection system and SCR catalyst enable the achievement of diesel
emissions requirements; while maintaining outstanding fuel economy, drivability,
torque and power ratings.
NOTE:
• Your vehicle is equipped with a DEF injection system. You may occasionally hear
an audible clicking noise. This is normal operation.
• The DEF pump will run for a period of time after engine shutdown to purge the DEF
system. This is normal operation.
Adding Diesel Exhaust Fluid
The DEF gauge (located in the EVIC) 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
Electronic Vehicle Information Center (EVIC).
NOTE:
• The gauge may take up to five seconds
to update after adding a gallon or more
of Diesel 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 au-
thorized dealer for service.
• The DEF gauge may also not immedi-
ately update after a refill if the tem-
perature of the DEF fluid is below 12°F
(-11°C). The DEF line heater will pos-
sibly 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.
