hold lower gears when not using
paddles. The shifts are also firmer to
increase the quickness of shifting.
Steering (Assist Effort)
Adjusts from a lighter steering feel in
Tour Mode to reduced assist in Sport
and Track Mode for more
steering feel.
Magnetic Ride Control (if equipped)
Adjusts the shock dampening
firmness from a comfort tune in Tour
Mode to an optimized responsiveness
tune in Sport and Track.
Launch Control (V-Series Only)
Available only in Track Mode for
maximum“off–the–line ”acceleration
when in Competitive or PTM Modes.
Stability Control
. Competitive Mode allows less
computer control to permit some
slide and drift and is selected with
the button –only available in
Track Mode.
. StabiliTrak can be turned off by
pressing and holding the button
for five seconds.Driver Mode Customization
The Engine Sound Management,
steering, and suspension drive modes
can be set to the driver’s preference.
See “Driving Mode ”under Vehicle
Personalization 0144.
When in the Track main vehicle mode,
you cannot overwrite the Steering or
Suspension settings. These settings
are designed to interact with the
advanced functions in the Track Mode
and cannot be overwritten.
The selections made in the Driving
Mode menu overwrite the main
vehicle mode selection via the buttons
or switch on the center console. In
order to customize and overwrite,
select one of the three settings by
touching the infotainment display.
When in the customization screen for
each system, select one of the
available options:
. Auto (Follows the MODE switch)
. Tour
. Sport
. Track The default will be to follow the
vehicle MODE switch settings, but the
main vehicle mode selection for the
currently selected system can be
overwritten using this menu. The
settings selected in this menu will set
the vehicle behavior in all selected
vehicle modes, and will be retained
over each ignition cycle. They do not
have to be reset each time the vehicle
is started.
Competitive Driving Mode
(V-Sport Only)
To select this optional handling mode,
press
Yquickly two times and the
DIC will display COMPETITIVE MODE
ON. While in the Competitive Driving
Mode, the traction off light
iand
StabiliTrak OFF light
gwill come on
in the instrument cluster. TCS does
not limit wheel spin, the Electronic
Limited-Slip Differential (eLSD) allows
increased vehicle agility, and more
effort is required to turn the steering
wheel. See “Limited-Slip Differential

11349156) - 2018 - CRC - 9/29/17
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
