5. Repeat Steps 1 to 4 to shift out of NEUTRAL.
NOTE:If shift conditions/interlocks are not met, a
“CHECK SHIFT PROCEDURES” message will flash from
the Electronic Vehicle Information Center (EVIC). Refer
to “Electronic Vehicle Information Center (EVIC)” in
Section 4 of this manual.
Quadra-Drive II System — If Equipped
The optional Quadra-Drive II System features three
torque transfer couplings. The couplings include Elec-
tronic Limited-Slip Differential (ELSD) front and rear
axles and Quadra-Trac II transfer case. The optional
ELSD axles are fully automatic and require no driver
input to operate. Under normal driving conditions, the
units function as standard axles, 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 couplings differ in
design, their operation is similar. Follow the Quadra-Trac
II transfer case shifting information, preceding this
section, for shifting this system.
Neutral Switch
260 STARTING AND OPERATING

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 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 TCS and ESP are in
either the “Partial Off” or “Full Off” modes. Refer to
“Electronic Stability Program (ESP)” in this section for
more 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
quickly results in the best BAS assistance. To receive the
benefit of the system, you must applycontinuousbrak-
ing pressure during the stopping sequence (do not
“pump” the brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
