This system relies on four microphones embedded in the
headliner to detect the exhaust drone and prompt an
onboard frequency generator to create counteracting
sound waves through the audio system’s speakers and
sub-woofer. This helps keep the vehicle quiet at highway
speeds.
Eight–Speed Automatic Transmission
The electronic shift lever in this vehicle does not slide like
a conventional shifter. Instead, the shift lever is spring
loaded and moves forward and rearward, always return-
ing to the center position after each gear is selected. The
transmission gear (PRND) is displayed both on the shift
lever and in the Driver Information Display (DID). To
select a gear range, press the lock button on the shift lever
and move the lever rearward or forward. You must also
press the brake pedal to shift the transmission out of
PARK, or to shift from NEUTRAL into DRIVE or RE-
VERSE when the vehicle is stopped or moving at lowspeeds (refer to “Brake/Transmission Shift Interlock Sys-
tem” in this section). To shift past multiple gear ranges at
once (such as PARK to DRIVE), move the lever past the
first (or second) detent. Select the DRIVE range for
normal driving.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when
shifting between these gears.
The transmission shift lever provides PARK, REVERSE,
NEUTRAL, DRIVE and SPORT shift positions. Once in
the DRIVE range, tapping the shift lever rearward will5

CAUTION!
•DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as this
can damage the drivetrain.
•Before moving the shift lever out of PARK, you
must start the engine, and also press the brake
pedal. Otherwise, damage to the shift lever could
result.
The following indicators should be used to ensure that
you have engaged the transmission into the PARK posi-
tion:
•When shifting into PARK, press the lock button on the
shift lever and push the lever all the way forward until
it stops. When released, the lever will return to the
center position.•With brake pedal released, look at the transmission
gear position display and verify that it indicates the
PARK position (P).
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking
brake and shift the transmission into PARK if you must
leave the vehicle.

•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.

audible chime will sound when the shift lever is moved
into the PARK position from any position other than
PARK and then moved out of the PARK position. This
will occur when the message was previously cleared.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled. There-
fore, the enhanced vehicle stability offered by ESC is
unavailable. In an emergency evasive maneuver, the
ESC system will not engage to assist in maintaining
