214 DRIVING AND OPERATING
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 Performance
Traction Management.
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
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 (V-Sport Only) 0211 and
Maintenance Schedule 0339.
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
0 206. If a collision alert occurs when

DRIVING AND OPERATING 217
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. See
Radio Frequency Statement
0367.
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 0206. 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. See Defensive
Driving 0178.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
