Performance Traction
Management (V-Series Only)
Performance Traction Management
(PTM) integrates the Traction Control,
StabiliTrak, and Selective Ride Control
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 the radius of each corner.
This light is on when the vehicle is in
the PTM mode.
To select this optional handling mode,
the vehicle mode must be Track. Then
quickly press
Yon the center
console two times. PERF TRAC 1 -

modes.
To select a mode while in PTM, press
the Driver Mode Control/PTM buttons
on the center console.
To experience the performance benefit
of this system, after entering a curve
and at the point where normal acceleration occurs, fully push the
accelerator pedal. The PTM system
will modify the level of engine power
for a smooth and consistent
corner exit.
The PTM system contains five modes.
These modes are selected by pressing
the Driver Mode Control/PTM buttons
on the center console. Scroll up or

Launch Control (V-Series Only)
A Launch Control feature is available,
within Competitive Driving Mode or
Performance Traction Management
(V-Series), to allow the driver to
achieve 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 (V-Series). The TCS light
comes on the instrument panel
and the appropriate DIC message
displays.
. The vehicle is not moving.
. The steering wheel is pointing
straight.
. The brake pedal must be 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.)

DRIVING AND OPERATING 217
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow the
engine rpm to stabilize. A smooth,
quick release of the brake pedal, while
maintaining the fully pressed
accelerator pedal, will manage
wheel slip.
After the vehicle is launched, the
system continues in Competitive
Driving Mode or Performance Traction
Management (V-Series).
Competitive Driving Mode, PTM, and
Launch Control are systems designed
for a closed course race track and not
intended for use on public roads. The
systems are not intended to
compensate for lack of driver
experience or familiarity with the race
track.Limited-Slip Differential
(Except V-Series)
If equipped, the mechanical
limited-slip differential can give more
traction on snow, mud, ice, sand,
or gravel. It works like a standard axle
most of the time, but when traction is
low, this feature allows the drive
wheel with the most traction to move
the vehicle. For vehicles with
limited-slip differential, driven under
severe conditions, the rear axle fluid
should be changed. SeeCompetitive
Driving Mode 0214 and Maintenance
Schedule 0324.
Limited-Slip Differential
(V-Series Only)
If equipped, the Electronic
Limited-Slip Differential (eLSD) is
automatically activated. eLSD actively
monitors vehicle sensors and driver
inputs to determine the amount of
change for the conditions. With eLSD,
the vehicle has:
.
Enhanced high-speed control. .
Improved traction through
corners, allowing more
acceleration.
. More precise steering.
. Increased vehicle agility.
. Integration with StabiliTrak.
For vehicles with eLSD, driven under
severe conditions, the rear axle fluid
should be changed. See Competitive
Driving Mode 0214 and Maintenance
Schedule 0324.

218 DRIVING AND OPERATING
Cruise Control
{Warning
Cruise control can be dangerous
where you cannot drive safely at a
steady speed. Do not use cruise
control on winding roads or in
heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could
lose control. Do not use cruise
control on slippery roads.
With cruise control, a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your foot
on the accelerator. Cruise control does
not work at speeds below about
40 km/h (25 mph).
If the StabiliTrak
®system begins to
limit wheel spin while using cruise
control, the cruise control
automatically disengages. See Traction
Control/Electronic Stability Control
0 209. If a collision alert occurs when cruise control is activated, cruise
control is disengaged. See
Forward
Collision Alert (FCA) System 0235.
When road conditions allow the cruise
control to be safely used, cruise
control can be turned back on.
If the brakes are applied, the cruise
control disengages.
J: Press to turn the system on and
off. A white indicator appears in the
instrument cluster when cruise is
turned on. +RES :
If there is a set speed in
memory, press the control up briefly
to resume to that speed or press and
hold to accelerate. If the cruise control
is already active, use to increase
vehicle speed. To increase speed by
1 km/h (1 mph), press +RES up to the
first detent. To increase speed to the
next 5 km/h (5 mph) mark on the
speedometer, press +RES up to the
second detent.
SET− :Press the control down briefly
to SET− to set the speed and activate
cruise control. If cruise control is
already active, use to decrease vehicle
speed. To decrease speed by 1 km/h
(1 mph), press SET− down to the first
detent. To decrease speed to the next
5 km/h (5 mph) mark on the
speedometer, press SET− down to the
second detent.*: Press to disengage cruise control
without erasing the set speed from
memory.

220 DRIVING AND OPERATING
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to increase
the vehicle speed. When you take your
foot off the pedal, the vehicle will slow
down to the previously set cruise
speed. While pressing the accelerator
pedal or shortly following the release
to override cruise control, briefly
applying the SET–switch will result in
cruise control set to the current
vehicle speed.
Using Cruise Control on Hills
How well the cruise control will work
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 the vehicle speed.
When going downhill, the cruise
control system may automatically
brake to slow the vehicle down (CTS
model only). Also, you may have to
brake or shift to a lower gear to keep
the vehicle speed down. If the brake
pedal is applied, cruise control
disengages. Ending Cruise Control
There are four ways to end cruise
control:
.
Step lightly on the brake pedal.
. Press
*.
. Shift the transmission to
N (Neutral).
. Press
J.
Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if
the ignition is turned off.
Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed and
following gap. Read this entire section
before using this system. The
following gap is the following time
between your vehicle and a vehicle
detected directly ahead in your path
moving in the same direction. If no
vehicle is detected in your path, ACC
works like regular cruise control. ACC
uses camera and radar sensors. If a vehicle is detected in your path,
ACC can apply acceleration or limited,
moderate braking to maintain the
selected following gap. To disengage
ACC, apply the brake. If ACC is
controlling your vehicle speed when
the Traction Control System (TCS) or
electronic stability control system
activates, the ACC may automatically
disengage. See
Traction Control/
Electronic Stability Control 0209. When
road conditions allow ACC to be safely
used, the ACC can be turned back on.
ACC will not engage if the TCS or
electronic stability control system is
disabled.{Warning
ACC has limited braking ability and
may not have time to slow the
vehicle down enough to avoid a
collision with another vehicle you
are following. This can occur when
vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver” in this section.
Complete attention is always

required while driving and you
should be ready to take action and
apply the brakes. SeeDefensive
Driving 0182.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
. On winding and hilly roads or
when the sensors are blocked
by snow, ice, or dirt. The
system may not detect a
vehicle ahead. Keep the entire
front of the vehicle clean.
. Visibility is low, such as in
fog, rain, or snow conditions.
ACC performance is limited
under these conditions.
. On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.
J:Press to turn the system on or
off. A white cruise control indicator
comes on.
+RES : Press the control up briefly to
resume the previous set speed or to
increase vehicle speed if ACC is
already activated. To increase speed
by 1 km/h (1 mph), press +RES up to
the first detent. To increase speed to
the next 5 km/h (5 mph) mark on the
speedometer, press +RES up to the
second detent.
SET– :Press the control down briefly
to set the speed and activate ACC or
to decrease vehicle speed if ACC is
already activated. To decrease speed by 1 km/h (1 mph), press SET−
down
to the first detent. To decrease speed
to the next 5 km/h (5 mph) mark on
the speedometer, press SET− down to
the second detent.
*: Press to disengage ACC without
erasing the set speed from memory.
[: Press to select a following gap
time (or distance) setting for ACC of
Far, Medium, or Near.
Setting Adaptive Cruise Control
If the cruise control is on when not in
use, the cruise on/off control could get
pressed and cruise control could
become active when not desired. Keep
cruise control button off when cruise
is not being used.
Select the set speed desired for cruise.
This is the vehicle speed when no
vehicle is detected in its path.
ACC will not set at a speed less than
25 km/h (16 mph), although it can be
resumed when driving at lower
speeds.
To set ACC:

flash on the windshield. Either eight
beeps will sound from the front,
or both sides of the Safety Alert Seat
will pulse five times. See“Collision/
Detection Systems” underVehicle
Personalization 0149.
See Defensive Driving 0182.
Approaching and Following a
Vehicle
The vehicle ahead symbol is in the
instrument cluster and HUD display,
if equipped.
The vehicle ahead symbol only
displays when a vehicle is detected in
your vehicle’s path moving in the
same direction.
If this symbol is not displaying, ACC
will not respond to or brake to
vehicles ahead. ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow the vehicle in front at the
selected follow gap. The vehicle speed
increases or decreases to follow the
vehicle in front of you, but will not
exceed the set speed. It may apply
limited braking, if necessary. When
braking is active, the brake lamps will
come on. The automatic braking may
feel or sound different than if the
brakes were applied manually. This is
normal.
Stationary or Very Slow-Moving
Objects{Warning
ACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a vehicle
it has never detected moving. This
can occur in stop-and-go traffic or
when a vehicle suddenly appears
due to a vehicle ahead changing
lanes. Your vehicle may not stop
and could cause a crash. Use
(Continued)
Warning (Continued)
caution when using ACC. Your
complete attention is always
required while driving and you
should be ready to take action and
apply the brakes.
ACC Automatically Disengages
ACC may automatically disengage and
the driver will need to manually apply
the brakes to slow the vehicle when:
. The sensors are blocked.
. The Traction Control System (TCS)
or electronic stability control
system has activated or been
disabled.
. No traffic or other objects are
being detected.
. There is a fault in the system.
The ACC active symbol will not be
displayed when ACC is no longer
active.
