Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.
WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
•Your vehicle could move and injure you and others
if it is not in PARK. Check by trying to move the
shift lever out of PARK with the brake pedal
released. Make sure the transmission is in PARK
before leaving the vehicle.
•It is dangerous to shift out of PARK or NEUTRAL
if the engine speed is higher than idle speed. If

during passing, city driving, cold slippery conditions,
mountain driving, trailer towing, and many other situa-
tions.
Operation
When the transmission is in DRIVE or SPORT mode, it
will operate automatically, shifting between the eight
available gears. To activate Paddle Shift mode, simply tap
one of the steering wheel-mounted shift paddles (+/-)
while in DRIVE or SPORT mode. Tapping (-) to enter
Paddle Shift mode will downshift the transmission to the
next lower gear, while using (+) to enter Paddle Shift
mode will retain the current gear. When Paddle Shift
mode is active, the current transmission gear is displayed
in the instrument cluster.
In Paddle Shift mode, the transmission will shift up or
down when (+/-) is manually selected by the driver,
unless an engine lugging or overspeed condition wouldresult. It will remain in the selected gear until another
upshift or downshift is chosen, except as described
below.
•Normally, in Paddle Shift mode, the transmission will
automatically shift up when maximum engine speed is
reached. If, however, Paddle Shift is engaged while in
SPORT or TRACK mode, the transmission will remain
in the selected gear even when maximum engine
speed is reached. The transmission will upshift only
when commanded by the driver.
•The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
•The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.

STARTING AND OPERATING 415

•You can start out, from a stop, in first or second gear
(or third gear, in SNOW mode). Tapping (+) (at a stop)
will allow starting in second gear. Starting out in
second gear can be helpful in snowy or icy conditions.
•If a requested downshift would cause the engine to
over-speed, that shift will not occur.
•The system will ignore attempts to upshift at too low
of a vehicle speed.
•Holding the (-) paddle depressed will downshift the
transmission to the lowest gear possible at the current
speed.
•Transmission shifting will be more noticeable when
Paddle Shift mode is enabled.
•The system may revert to automatic shift mode if a
fault or overheat condition is detected.To disengage Paddle Shift mode, press and hold the (+)
shift paddle until “D” or “S” is once again indicated in
the instrument cluster. You can shift in or out of Paddle
Shift mode at any time without taking your foot off the
accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
SELEC-TRACK® — IF EQUIPPED
Description
Selec-Track™ combines the capabilities of the vehicle
control systems, along with driver input, to provide the
best performance for all terrains.
416 STARTING AND OPERATING

Selec-Track™ consists of the following positions:
•Sport– Dry weather, on-road calibration. Performance
based tuning that provides a rear wheel drive feel but
with improved handling and acceleration over a two-
wheel drive vehicle. The customer has the option of
going to partial ESC. The active suspension systemwill be in Firm mode and the transmission will be in
SPORT shift mode then and a green flag will light up
in the instrument cluster. The transmission will pro-
vide a more aggressive shifting pattern (Refer to
“Paddle Shift Mode” in “Starting And Operating” for
further information). This feature will reset to AUTO
on an ignition cycle.
•Snow– Tuning set for additional stability in inclement
weather. Use on and off road on loose traction surfaces
such as snow. When in Snow mode (depending on
certain operating conditions), the transmission may
use second gear (rather than first gear) during
launches, to minimize wheel slippage. This feature will
reset to AUTO upon an ignition cycle.
•Auto– Fully automatic full time four-wheel drive
operation can be used on and off road. Balances
Selec-Track™ Switch

traction with seamless steering feel to provide im-
proved handling and acceleration over two-wheel
drive vehicles. The active suspension system will be in
Touring Mode.
•Track– Track road calibration for use on high traction
surfaces. Driveline is maximized for traction. Some
binding may be felt on less forgiving surfaces. The
electronic brake controls are set to Partial OFF to limit
traction control management of throttle and wheel
spin.
•The transmission will be in SPORT shift mode and
provide a more aggressive shifting pattern. Refer to
“Paddle Shift Mode” in “Starting And Operating”
for further information.
•The customer has the option of going to FULL OFF
with no interaction from the ESC System. The active
suspension system will be in Full Firm mode.
•This feature will reset to AUTO on an ignition cycle.•To w– Use this mode for towing. Vehicle suspension
will go to Firm mode. Trailer sway control is enabled
in the ESC system. The terrain switch will remain in
this position through an ignition cycle until the cus-
tomer cycles into another position. This feature will
reset to AUTO upon an ignition cycle.
Active Damping System
This vehicle is equipped with an electronic controlled
damping system. This system reduces body roll and pitch
in many driving situations including cornering, accelera-
tion and braking. There are 3 modes:
•Touring Mode(Available in terrain positions AUTO
and SNOW) — Used during highway speeds where a
touring suspension feel is desired.
•Firm Mode(Available in terrain positions SPORT and
TOW) — Provides a firm suspension for better han-
dling.
418 STARTING AND OPERATING

•Full Firm(Available in TRACK mode) — Provides a
full firm suspension for an aggressive track experience.
Launch Mode — If Equipped
This system maximizes acceleration traction for straight
line racing. To use Launch Mode please follow the steps
below:
1. Bring vehicle to complete stop on a level track surface
with the engine running.
2. Set the steering wheel for straight ahead driving.
3. Fully press the brake pedal.
4. Press and release the “LAUNCH” Button.
5. Press the accelerator pedal to the floor.
NOTE:If the cluster launch DID message indicates all
conditions are correct for launch and the throttle is
pressed to the floor quickly (within approximately 1/2second) the system will hold the engine speed to a preset
speed (below the engine rev limiter speed).
6. Release the brake pedal.
Pressing the launch control button when launch control is
active will deactivate launch control.
NOTE:
•Launch Mode brings the engine to optimum RPM and
waits for the driver to release the brake. Launch Mode
then uses engine throttle only to achieve controlled
wheelslip for maximum acceleration through 62 mph
(100 km/h).
•Launch Mode can be initiated in any of the Select Trac
Modes.
•Launch Mode is not available until the 500 mile
(805 km) break-in has been achieved.

Warranty.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.NOTE:
•Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
•Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
422 STARTING AND OPERATING

NOTE:
•When the parking brake is applied and the transmis-
sion is placed in gear, the “Brake” Warning Light will
flash. If vehicle speed is detected, a chime will sound
to alert the driver. Fully release the parking brake
before attempting to move the vehicle.
•This light only shows that the parking brake is ap-
plied. 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 substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
•When leaving the vehicle, always remove the Key
Fob from the ignition and lock your vehicle.
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the shift lever.
•When leaving the vehicle, always make sure the
keyless ignition node is in the “OFF” mode, re-
move the Key Fob from the vehicle and lock the
vehicle.

424 STARTING AND OPERATING

brakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating.
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 vehicle stability and
control in various driving conditions.
Also, your vehicle is equipped with Trailer Sway Control
(TSC).
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controlshydraulic brake pressure to prevent wheel lock-up and
help avoid skidding on slippery surfaces during braking.
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 collisions, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. The capa-
bilities of an ABS-equipped vehicle must never be
exploited 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
426 STARTING AND OPERATING

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 thenapplies 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.
WARNING!
•The BAS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
the traction afforded by prevailing road conditions.
•The BAS cannot prevent collisions, including those
resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
