6. Using a ballpoint pen or similar object, push and hold
the recessed transfer case “N” button (located by the
selector switch) for one second.
7. When the NEUTRAL (N) indicator light turns off,
release the NEUTRAL (N) button.
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 Differential (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 func-
tions 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

CAUTION!
Do not drive in 4WD-LOW Range on dry pavement;
driveline damage may result. 4WD-LOW Range
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.
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.
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. Driv-
ing through water may cause damage that may not be
covered by the new vehicle limited warranty.
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
462 STARTING AND OPERATING

CAUTION!
The Anti-Lock Brake System is subject to possible
detrimental effects of electronic interference caused
by improperly installed aftermarket radios or tele-
phones.
NOTE:During severe braking conditions, a pulsing sen-
sation may occur and a clicking noise will be heard. This
is normal, indicating that the Anti-Lock Brake System is
functioning.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability.
A feature of the TCS system, Brake Limited Differential
(BLD), functions similar 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 torque to be applied to the wheel
that is not spinning. This feature remains active even if
ESC system is in the “Partial Off” mode. Refer to “Elec-
tronic Stability Control (ESC)” in this section for further
information.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very
