5. Repeat Steps 1 to 4 to shift out of NEUTRAL.
NOTE:
If shift conditions/interlocks are not met, a
“To Tow Vehicle Safely, Read Neutral ShiftProcedure in Owners Manual” message will
flash from the Electronic Vehicle Informa-
tion Center (EVIC). Refer to “Electronic Ve-
hicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further

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 trans-
fer case. The optional ELSD axle is fully auto-
matic 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 differ-
ence. 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.

•This light only shows that the parking
brake is applied. It does not show the
degree of brake application.
When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill
grade and away from the curb on an uphill
grade. Apply the parking brake before placing
the shift lever in PARK, otherwise the load on
the transmission locking mechanism may make
it difficult to move the shift lever out of PARK.
The parking brake should always be applied
whenever the driver is not in the vehicle.
WARNING!
• Never use the PARK position as a substi-
tute for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible
injury or damage.
•
Never leave children alone in a vehicle.
Leaving unattended children in a vehicle is
dangerous for a number of reasons. A child
or others could be seriously or fatally injured.
(Continued)
WARNING! (Continued)
• Do not leave the key fob in the ignition
switch. A child could operate power win-
dows, other controls, or move the vehicle.
• Be sure the parking brake is fully disen-
gaged before driving; failure to do so can
lead to brake failure and a collision.
• Always fully apply the parking brake when
leaving your vehicle, or it may roll and
cause damage or injury. Also be certain to
leave the transmission in PARK. Failure to
do so may allow the vehicle to roll and
cause damage or injury.
CAUTION!
If the “Brake Warning Light” remains on with
the parking brake released, a brake system
malfunction is indicated. Have the brake sys-
tem serviced by an authorized dealer imme-
diately.
ELECTRONIC BRAKE CONTROL
SYSTEM
Your vehicle is equipped with an advanced
electronic brake control system that includes
the Anti-Lock Brake System (ABS), Traction
Control System (TCS), Brake Assist System
(BAS), Electronic Roll Mitigation (ERM), and
Electronic Stability Control (ESC). All five of
these systems work together to enhance ve-
hicle stability and control in various driving
conditions.
Also, your vehicle is equipped with Trailer Sway
Control (TSC), Hill Start Assist (HSA), Brake
Lock Differential (BLD), Ready Alert Braking,
Rain Brake Support and, if it has four-wheel
drive with the MP 3023 two-speed transfer
case, Hill Descent Control (HDC).
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining ve-
hicle control under adverse braking conditions.
The system controls hydraulic brake pressure
to prevent wheel lock-up and help avoid skid-
ding on slippery surfaces during braking.
223

WARNING!
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase the traction afforded by prevailing
road conditions. The ABS cannot prevent ac-
cidents, including those resulting from exces-
sive speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of
an ABS-equipped vehicle must never be ex-
ploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the
safety of others.
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 sys-tem 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 “Electronic Stability
Control (ESC)” in this section for further infor-
mation.
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 sensing the rate and
amount of brake application and then applies
optimum pressure to the brakes. This can help
reduce braking distances. The BAS comple-
ments the anti-lock brake system (ABS). Apply-
ing the brakes very quickly results in the best
BAS assistance. To receive the benefit of the
system, you must apply
continuousbraking
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.
WARNING!
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase the traction afforded by prevailing
road conditions. The BAS cannot prevent
accidents, including those resulting from ex-
cessive speed in turns, driving on very slip-
pery surfaces, or hydroplaning. The capabili-
ties of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the
safety of others.
Electronic Roll Mitigation (ERM)This system anticipates the potential for wheel
lift by monitoring the driver’s steering wheel
input and the speed of the vehicle. When ERM
determines that the rate of change of the steer-
ing wheel angle and vehicle speed are suffi-
cient to potentially cause wheel lift, it then
applies the brake of the appropriate wheel and
may also reduce engine power to lessen the
chance that wheel lift will occur. ERM will only
intervene during very severe or evasive driving
maneuvers.
