The 4WD LOW light will remain on solid when the shift is
complete.

4WD LOW Button

NOTE:If shift conditions/interlocks are not met a message will
show on the instrument cluster display with instructions
required to complete the shift
Úpage 99.
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 position or the engine running,
shift the transmission into NEUTRAL (N), and push the
4WD LOW button once on the transfer case switch until
the 4WD LOW indicator light begins to flash in the
instrument cluster. The 4WD LOW light will go out when
the shift is complete.
NOTE:
If shift conditions/interlocks are not met a message
will show on the instrument cluster display with instruc -
tions required to complete the shift
Úpage 99.
 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.
QUADRA-DRIVE II SYSTEM —
I
F EQUIPPED
The Quadra-Drive II System features two torque transfer
couplings. The couplings include an Electronic
Limited-Slip Differential (ELSD) rear axle and the
Quadra-Trac II transfer case. The ELSD axle is fully
automatic and requires no driver input to operate. Under
normal driving conditions, the unit functions as a standard
axle, balancing 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
automatically transfer from the wheel that has less
traction, to the wheel that has traction. While the transfer
case and axle coupling differ in design, their operation is
similar. Follow the Quadra-Trac II transfer case shifting
information, preceding this section, for shifting this
system.
SELEC-TERRAIN — IF EQUIPPED
SELEC-TERRAIN MODE SELECTION
Selec-Terrain combines the capabilities of the vehicle
control systems, along with driver input, to provide the
best performance for all terrains. Tap the toggle up or
down to cycle through the positions.

194STARTING AND OPERATING
When To Use 4WD LOW — If Equipped
When off-road driving, shift to 4WD LOW for additional
traction. This range should be limited to extreme
situations such as deep snow, mud, or sand where
additional low speed pulling power is needed. Vehicle
speeds in excess of 25 mph (40 km/h) should be avoided
when in 4WD LOW.
Driving Through Water
Although your vehicle is capable of driving through water,
there are a number of precautions that must be
considered before entering the water.
NOTE:Your vehicle is capable of water fording in up to 20 inches
(51 cm) of water, while crossing small rivers or streams. To
maintain optimal performance of your vehicle's heating
and ventilation system it is recommended to switch the
system into recirculation mode during water fording. Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle. If you must
drive through water, try to determine the depth and the
bottom condition (and location of any obstacles) prior to
entering. Proceed with caution and maintain a steady
controlled speed less than 5 mph (8 km/h) in deep water
to minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm run-off),
avoid crossing until the water level recedes and/or the
flow rate is reduced. If you must cross flowing water avoid
depths in excess of 9 inches (23 cm). The flowing water
can erode the streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are
downstream of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than 24 inches
(60 cm), and reduce speed appropriately to minimize
wave effects. Maximum speed is 5 mph (8 km/h).Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to ensure the fluids have not been
contaminated. Contaminated fluid (milky, foamy in
appearance) should be flushed/changed as soon as
possible to prevent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4WD LOW if necessary
Úpage 129. Only shift into a lower gear to maintain
forward motion. Over-revving the engine can spin the
wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads, because
engine braking may cause skidding and loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the conditions
at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to 4WD LOW. Use
FIRST gear and 4WD LOW for very steep hills.
WARNING!
Do not drive in 4WD LOW on dry pavement; driveline
damage may result. 4WD LOW locks front and rear
drivelines together and does not allow for differential
action between the front to rear driveshafts. Driving in
4WD LOW on pavement will cause driveline binding;
use only on wet or slippery surfaces.
CAUTION!
When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering as
a precaution, and check all fluids afterward. Driving
through water may cause damage that may not be
covered by the New Vehicle Limited Warranty.

246SAFETY
The set speed for SSC is selectable by the driver, and can
be adjusted by using the gear shift +/-. Additionally, the
SSC set speed may be reduced when climbing a grade and
the level of set speed reduction depends on the
magnitude of grade. The following summarizes the SSC
set speeds:
SSC Target Set Speeds
1st = .6 mph (1 km/h)
 2nd = 1.2 mph (2 km/h)
 3rd = 1.8 mph (3 km/h)
 4th = 2.5 mph (4 km/h)
 5th = 3.1 mph (5 km/h)
 6th = 3.7 mph (6 km/h)
 7th = 4.3 mph (7 km/h)
 8th = 5 mph (8 km/h)
 9th = 5.6 mph (9 km/h) – If Equipped
 REVERSE = .6 mph (1 km/h)
 NEUTRAL = 1.2 mph (2 km/h)
 PARK = SSC remains enabled but not active
NOTE:
During SSC the +/- shifter input is used for SSC target
speed selection but will not affect the gear chosen by
the transmission. While actively controlling SSC the
transmission will shift appropriately for the
driver-selected set speed and corresponding driving
conditions.
 SSC performance is influenced by the Select-Terrain
mode. This difference may be notable to the driver and
may be perceived as a varying level of aggressiveness. Driver Override:
The driver may override SSC activation with throttle or
brake application at any time.
Deactivating SSC
SSC will be deactivated but remain available if any of the
following conditions occur:

Driver overrides SSC set speed with throttle or brake
application
 Vehicle speed exceeds 20 mph (32 km/h) but remains
below 40 mph (64 km/h)
 Vehicle is shifted to PARK
Disabling SSC
SSC will deactivate and be disabled if any of the following
conditions occur:
 The driver pushes the SSC switch.
 The driveline is shifted out of 4WD Low.
 The parking brake is applied.
 The driver door opens.
 The vehicle is driven greater than 20 mph (32 km/h)
for greater than 70 seconds.
 The vehicle is driven greater than 40 mph (64 km/h)
(SSC exits immediately).
Feedback To The Driver:
The instrument cluster has an SSC icon and the SSC
switch has an LED which offers feedback to the driver
about the state SSC is in.
 The cluster icon and switch light will illuminate and
remain on solid when SSC is enabled or activated. This
is the normal operating condition for SSC. 
The cluster icon and switch light will flash for several
seconds then extinguish when the driver pushes the
SSC switch but enable conditions are not met.
 The cluster icon and switch light will flash for several
seconds then extinguish when SSC disables due to
excess speed.
 The cluster icon and switch light will flash then extin -
guish when SSC deactivates due to overheated brakes.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce
engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD) functions similarly to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will
allow more engine power to be applied to the wheel that is
not spinning. BLD may remain enabled even if the TCS and
Electronic Stability Control (ESC) are in reduced modes.
WARNING!
SSC is only intended to assist the driver in controlling
vehicle speed when driving in off-road conditions. The
driver must remain attentive to the driving conditions
and is responsible for maintaining a safe vehicle speed.
