downshift the transmission. The
right (+) plus paddle upshifts, and
the left (−) minus paddle downshifts
When using the Manual Paddle
Shift feature while in M (Manual
Mode), the current gear will be
displayed in the instrument cluster,
or the Head-Up Display (HUD),
if equipped. SeeHead-Up Display
(HUD) on page 5-29.
When accelerating the vehicle from
a stop in snowy and icy conditions,
shifting to 2 (Second) or 3 (Third)
gear allows the vehicle to gain more
traction.
The Manual Paddle Shift system
can be deactivated by moving the
shift lever from M (Manual Mode)
back to D (Drive). When the shift lever is in D (Drive),
press either the right (+) plus paddle
or the left (−) minus paddle to place
the transmission in Temporary
Manual Paddle Shift mode. The
gear indicator by the shift lever, in
the cluster, and in the HUD will
display an M, even though the shift
lever is still in D (Drive). To exit the
system, hold the (+) plus paddle for
more than one second. The system
will return to automatic shifting after
six seconds of cruising at a steady
speed, no manual shifts, no
aggressive cornering, or when the
vehicle comes to a stop.
While the Manual Paddle Shift gear
selection system is active, the
transmission will automatically
downshift through the gears as the
vehicle slows. The transmission will
select 1 (First) gear as the vehicle
stops. From a stop, the vehicle will
start from and hold 1 (First) gear
unless the manual paddle shifts are
used to shift into a different gear,
or D (Drive) is selected.If the left (−) minus paddle is held
down briefly, the transmission will
downshift to the lowest gear
possible for the vehicles speed.
If the paddle continues to be held as
the vehicle slows, downshifts will
continue to occur as vehicle speed
allows. This feature also works
while in Temporary Manual Paddle
Shift mode, but the driver must first
press and release the (−) minus
paddle to enter Temporary Manual
Paddle Shift mode, then press and
hold the (−) minus paddle briefly.
The Manual Paddle Shift system will
not allow either an upshift or a
downshift if the vehicle speed is too
fast or too slow, nor will it allow a
start from 4 (Fourth) or higher gear.
If upshifting does not occur when
needed, vehicle speed will be
limited to protect the engine.
When a requested shift is denied
due to the speed restrictions shown,
a DIC message will be displayed,
and the current gear remains
displayed in the cluster and HUD.

gbutton–only
available in Track mode.

Competitive Driving Mode
If equipped, 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, brake,
and suspension are advised to turn
the normal traction control and
StabiliTrak systems 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 vehicle
warranty. Do not attempt to shift
when the drive wheels do not
have traction.
Competitive Driving Mode
(Except Z51 and Z06 with
Magnetic Ride Control)
Competitive Driving Mode allows full
engine power while StabiliTrak
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.

9-50 Driving and Operating
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain your
speed. When going downhill, you
might have to brake or shift to a
lower gear to keep your speed
down. If the brake pedal is applied,
cruise control will disengage.
Cruise Control in Manual Paddle
Shift Gear Selection
When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are not being used, cruise
control operates in the same
manner as D (Drive).
When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are being used, cruise
control operates as follows:
.If cruise control is active and a
gear is selected with the manual
paddle shift controls, the vehiclespeed is maintained in the driver
selected gear and will not
automatically upshift or
downshift the transmission while
the driver
’s gear selection is
active.
.If driving in hilly terrain, cruise
control may not be able to
maintain vehicle speed if an
upshift or downshift is not
selected by the driver. While
driving on hilly terrain and cruise
control is active with a manual
paddle shift gear selection, the
driver must select the proper
gear for the terrain or select D
(Drive) on the gear range
selector for full automatic
transmission operation.
Ending Cruise Control
.Step lightly on the brake pedal.
.If equipped with a manual
transmission, press the clutch
pedal for several seconds or
shift to Neutral to disengage
cruise control.
.Press*.
.To turn off cruise control,
press
1.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
1is pressed
or if the ignition is turned off.
