provide improved throttle response and modi-
fied shifting for an enhanced driving experi-
ence, as well the greatest amount of steeringfeel. This mode may be activated and deac-
tivated by pushing the Sport button on the
instrument panel switch bank.
FOUR WHEEL DRIVE
OPERATION
Quadra-Trac I Operating Instructions/
Precautions — If Equipped
The Quadra-Trac I is a single-speed (HI range
only) transfer case, which provides conve-
nient full-time four-wheel drive. No driver
interaction is required. The Brake Traction
Control (BTC) System, which combines stan-
dard ABS and Traction Control, provides re-
sistance to any wheel that is slipping to allow
additional torque transfer to wheels with trac-
tion.
NOTE:
The Quadra-Trac I system is not appropriate
for conditions where 4WD LOW range is rec-
ommended. Refer to “Off-Road Driving Tips”
in “Starting And Operating” in the Owner’s
Manual.

WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL position
without first fully engaging the parking
brake. The transfer case NEUTRAL posi-
tion disengages both the front and rear
drive shafts from the powertrain and will
allow the vehicle to roll, even if the trans-
mission is in PARK. The parking brake
should always be applied when the driver
is not in the vehicle.
4WD LOW
This range is for low speed four-wheel drive. It
provides an additional gear reduction which
allows for increased torque to be delivered to
both the front and rear wheels while providing
maximum pulling power for loose, slippery
road surfaces only. Do not exceed 25 mph
(40 km/h).
NOTE:
Refer to “Selec-Terrain — If Equipped” for
further information on the various positions
and their intended usages.
Shifting Procedures

8. After the NEUTRAL (N) button has been
released, the transfer case will shift to the
position indicated by the selector switch.
Quadra-Drive II System — If Equipped
The optional Quadra-Drive II System features
two torque transfer couplings. The couplings
include an Electronic Limited-Slip Differen-
tial (ELSD) rear axle and the Quadra-Trac II
transfer case. The optional ELSD axle is fully
automatic and requires no driver input to
operate. Under normal driving conditions,
the unit functions as a standard axle, balanc-
ing torque evenly between left and right
wheels. With a traction difference between
left and right wheels, the coupling will sense
a speed difference. As one wheel begins to
spin faster than the other, torque will auto-
matically transfer from the wheel that has
less traction, to the wheel that has traction.
While the transfer case and axle coupling

When the ParkSense Active Park Assist sys-
tem is enabled the “Active ParkSense
Searching - Push OK to Switch to Perpen-
dicular” message will appear in the instru-
ment cluster display. You may switch to per-
pendicular parking if you desire. Push the OK
button on the left side steering wheel switch
to change your parking space setting. You
may switch back to parallel parking if you
desire.
When searching for a parking space, use the
turn signal indicator to select which side of
the vehicle you want to perform the parking
maneuver.
NOTE:
If the turn signal is not activated, the
ParkSense Active Park Assist system will au-
tomatically search for a parking space on the
passenger's side of the vehicle.
Refer to your Owner's Manual for further
information.LANESENSE
LaneSense Operation
The LaneSense system is operational at
speeds above 37 mph (60 km/h) and below
112 mph (180 km/h). The LaneSense system
uses a forward looking camera to detect lane
markings and measure vehicle position
within the lane boundaries.
When both lane markings are detected and
the driver unintentionally drifts out of the
lane (no turn signal applied), the LaneSense
system provides a haptic warning in the form
of torque applied to the steering wheel to
prompt the driver to remain within the lane
boundaries. If the driver continues to unin-
tentionally drift out of the lane, the Lane-
Sense system provides a visual warning
through the instrument cluster display to
prompt the driver to remain within the lane
boundaries.The driver may manually override the haptic
warning by applying torque into the steering
wheel at any time.
When only a single lane marking is detected
and the driver unintentionally drifts across
the lane marking (no turn signal applied), the
LaneSense system provides visual and haptic
warnings through the instrument cluster dis-
play to prompt the driver to remain within the
lane. When only a single lane marking is
detected, a haptic (torque) warning will not
be provided.
NOTE:
When operating conditions have been met,
the LaneSense system will monitor if the
driver’s hands are on the steering wheel and
provides an audible warning to the driver
when the driver’s hands are not detected on
the steering wheel. The system will cancel if
the driver does not return their hands to the
wheel.

System Overview
This vehicle is equipped with a Diesel Ex-
haust 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.Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
system messages and warnings.
NOTE:
• Your vehicle is equipped with a DEF injec-
tion system. You may occasionally hear an
audible clicking noise from under the ve-
hicle at a stop. 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 and may
be audible from the rear of the vehicle.
Diesel Exhaust Fluid Storage
Diesel Exhaust Fluid (DEF) is considered a
very stable product with a long shelf life. If
DEF is kept in temperatures between 10° and
90°F (-12° and 32°C), it will last a minimum
of one year.
DEF is subject to freezing at the lowest tem-
peratures. For example, DEF may freeze at
temperatures at or below 12° F (-11° C). The
system has been designed to operate in this
environment.
NOTE:
When working with DEF, it is important to
know that:
• Any containers or parts that come into con-
tact with DEF must be DEF compatible
(plastic or stainless steel). Copper, brass,
aluminum, iron or non-stainless steel
should be avoided as they are subject to
corrosion by DEF.
• If DEF is spilled, it should be wiped up
completely.
