deflectors, if equipped, provide additional
cooling to the power steering gear during
track events. Remove the noise shields and
install the deflectors as directed by the
enclosed instruction sheet. Remove the
deflectors and reinstall the noise shields
immediately after track use to protect the
engine compartment from additional water
intrusion.

20 Driving and Operating
P :This position locks the drive wheels. It is
the best position to use when starting the
engine because the vehicle cannot move
easily.
{Warning
It is dangerous to get out of the vehicle
if the shift lever is not fully in P (Park)
with the parking brake firmly set. The
vehicle can roll.
Do not leave the vehicle when the engine
is running. If you have left the engine
running, the vehicle can move suddenly.
You or others could be injured. To be
sure the vehicle will not move, even
(Continued)
Warning (Continued)
when you are on fairly level ground,
always set the parking brake and move
the shift lever to P (Park).
Make sure the shift lever is fully in P (Park)
before starting the engine. The vehicle has
an automatic transmission shift lock control
system. The regular brake must be fully
applied first and then the shift lever button
must be pressed before shifting from
P (Park) when the ignition is on. If you
cannot shift out of P (Park), ease pressure on
the shift lever, then push the shift lever all
the way into P (Park) as you maintain brake
application. Then press the shift lever button
and move the shift lever into another gear.
R : Use this gear to back up.
Caution
Shifting to R (Reverse) while the vehicle is
moving forward could damage the
transmission. The repairs would not be
covered by the vehicle warranty. Shift to
R (Reverse) only after the vehicle is
stopped. N :
In this position, the engine does not
connect with the wheels. To restart the
engine when the vehicle is already moving,
use N (Neutral) only.
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is firmly on
the brake pedal, the vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while the engine is running at
high speed.
Caution
Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may
damage the transmission. The repairs
would not be covered by the vehicle
warranty. Be sure the engine is not
running at high speed when shifting the
vehicle.
D : This position is for normal driving.
If more power is needed for passing, press
the accelerator pedal down.

Caution
If the vehicle does not shift gears, the
transmission could be damaged. Have the
vehicle serviced right away.
Performance Shifting
While driving in Sport Mode and Track
Mode, if Tap Shift has not been activated,
the transmission determines when the
vehicle is being driven in a competitive
manner. The transmission may remain in a
gear longer than it would in the normal
driving mode based on throttle input and
vehicle lateral acceleration. If there is a rapid
reduction in throttle from a heavy throttle
position at high rpm, the transmission will
maintain the current gear up to near redline
rpm. While braking, the transmission will
automatically downshift to the next lower
gear keeping engine speed above
approximately 3000 rpm. If the vehicle is
then driven for a short time at a steady
speed, and without high cornering loads, the
transmission will upshift one gear at a time,
until 10 (Tenth) gear. After shifting to
10 (Tenth) gear, or coming to a complete
stop, the transmission will return to normal
Sport Mode shifting.
Ride Control Systems
Competitive Driving Mode
Competitive Driving Mode, Performance
Traction Management, and Launch Control
are systems designed to allow increased
performance while accelerating and/or
cornering. This is accomplished by regulating
and optimizing the engine, brakes, and
suspension performance. These modes are
for use at a closed course race track and are
not intended for use on public roads. They
will not compensate for driver inexperience
or lack of familiarity with the race track.
Drivers who prefer to allow the system to
have more control of the engine, brakes,
and suspension are advised to turn the
normal Traction Control System (TCS) and
StabiliTrak/Electronic Stability Control
(ESC) on.
Caution
Attempting to shift when the drive
wheels are spinning and do not have
traction may cause damage to the
transmission. Damage caused by misuse
of the vehicle is not covered by the
(Continued)
Caution (Continued)
vehicle warranty. Do not attempt to shift
when the drive wheels do not have
traction.
Competitive Driving Mode allows full engine
power while StabiliTrak/ESC helps maintain
directional control of the vehicle by selective
brake application. In this mode, TCS is off
and Launch Control is available. Adjust your
driving style to account for the available
engine power. See “Launch Control”later in
this section.
Do not use cruise control in performance
driving situations.
When StabiliTrak/ESC is in a performance
driving state by pressing
Ytwice for
Competitive Driving Mode or Performance
Traction Management Mode, or by pressing
and holding
Yfor five seconds to turn
StabiliTrak/ESC off, the cruise control
buttons on the left side of the steering
wheel will be inoperative.
To regain cruise control capability, press
Y
once to return to regular StabiliTrak/ESC
operation.

Performance Traction Management
(PTM) (ZL1 and SS 1LE)
PTM is not available on convertibles.
Convertibles have Competitive Driving Mode
instead. See“Competitive Driving Mode”
previously in this section.
PTM integrates the TCS, StabiliTrak/ESC, and
Competitive Driving Mode systems to
provide improved and consistent
performance when cornering. The amount of
available engine power is based on the
mode selected, track conditions, driver skill,
and radius of each corner.
These lights are on when the vehicle is in
PTM Mode.

gwill go out.
Launch Control
If equipped, Launch Control is available
within Competitive Driving Mode and
Performance Traction Management (PTM) to
allow high levels of vehicle acceleration in a
straight line. Launch Control is a form of
traction control that manages tire spin while
launching the vehicle. This feature is
intended for use during closed course race
events where consistent zero to
60 and quarter mile times are desirable.
Launch Control is only available when the
following criteria are met:
.Competitive Driving Mode is selected or
any of the Performance Traction
Management modes are selected. The
traction off light comes on in the
instrument cluster and the appropriate
Driver Information Center (DIC) message
displays.
.The vehicle is not moving.
.The steering wheel is pointing straight.
Manual Transmissions
.The clutch is fully pressed and the
transmission is in 1 (First) gear.
.The accelerator pedal is rapidly applied
and held to wide open throttle. Launch Control will initially limit engine
speed as you rapidly apply the accelerator
pedal to wide open throttle. Allow the
engine rpm to stabilize. A smooth, quick
release of the clutch, while maintaining the
fully pressed accelerator pedal, will manage
wheel slip.
Automatic Transmissions
.The brake pedal is firmly pressed to the
floor, equivalent to a panic brake event.
.The accelerator pedal is rapidly applied to
wide open throttle. If the vehicle rolls due
to wide open throttle, release the
throttle, press the brake pedal more
firmly, and re-apply the accelerator to
wide open throttle.
Launch Control will initially limit engine
speed as you rapidly apply the accelerator
pedal to wide open throttle. Allow the
