184 DRIVING AND OPERATING
If cruise control is being used and TCS
or StabiliTrak/ESC begins to limit
wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road conditions
allow.
Both systems come on automatically
when the vehicle is started and begins
to move. The systems may be heard or
felt while they are operating or while
performing diagnostic checks. This is
normal and does not mean there is a
problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary to
turn TCS off if the vehicle gets stuck
in sand, mud, ice, or snow. SeeIf the
Vehicle Is Stuck 0159 and “Turning
the Systems Off and On ”later in this
section.The indicator light for both systems is
in the instrument cluster. This
light will:
. Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak/ESC is
activated.
. Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message may display in the
Driver Information Center (DIC), and
dcomes on and stays on to indicate
that the system is inactive and is not
assisting the driver in maintaining
control. The vehicle is safe to drive,
but driving should be adjusted
accordingly.
If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine. Drive the vehicle. if
dcomes on and
stays on, the vehicle may need more
time to diagnose the problem. If the
condition persists, see your dealer.
Turning the Systems Off and On
Caution
Do not repeatedly brake or
accelerate heavily when TCS is off.
The vehicle driveline could be
damaged.

switch on the center console to make
a mode selection. Every press will
scroll to the next available mode.
When a mode is selected, a unique
and persistent indicator will be
displayed in the driver information
center (DIC).
V-Mode Button
To activate V-Mode, press the V-Mode
button on the steering wheel. To
deactivate, the driver can either select
a different mode through the DMC
switch or press the V-Mode button on
the steering wheel. When V-Mode is
deactivated through the V-Mode
button, DMC is always set back to
Tour Mode.
Mode Description
Tour Mode
Use for normal city and highway
driving to provide a smooth, soft ride.
This setting provides a balanced
setting between comfort and handling.
This is the standard mode. For further
details on Tour Mode see “Driver
Mode Selector Attributes Affected ”.
When Tour Mode is selected, no
indicator will display.
Sport Mode
Use where road conditions or personal
preference demand a more controlled
response.
When selected, the Sport Mode
indicator will display.
In this mode, the vehicle monitors
driving behaviors and automatically
enables Performance Shift Features
when spirited driving is detected.
These features maintain lower
transmission gears to increase
available engine braking and improve
acceleration response. The vehicle will
exit this feature and return to normal
operation after a short period when no spirited driving is detected. The
steering will change to provide more
precise control. If the vehicle has
Magnetic Ride Control, the suspension
will change to provide better
cornering performance. Competitive
Driving Mode (Only available on FE3
suspensions) can be accessed through
this mode. See
Competitive Driving
Mode 0191.
For further details on Sport Mode, see
“Driver Mode Selector Attributes
Affected”.
The Performance Algorithm Liftfoot
(PAL) feature is enabled in Sport
Mode. PAL allows the transmission to
hold the current gear after a quick
release of a heavily applied accelerator
pedal. This provides greater engine
braking and enhanced vehicle control.
When PAL is activated, there may be
an additional green gear symbol which
appears in the instrument cluster
display. See Performance Shifting Light
0 111.

Snow/Ice Mode
Snow/Ice Mode is used for slippery
surfaces to help control wheel speed.
This can compromise the acceleration
on dry asphalt.
Snow/Ice Mode will use a different
accelerator pedal map to optimize
traction on a slippery surface. The
accelerator pedal will reduce engine
torque at small pedal inputs.
When selected, the Snow/Ice Mode
indicator will display.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow, or gravel. If the
vehicle becomes stuck, seeIf the
Vehicle Is Stuck 0159.
For further details on Snow/Ice Mode
see “Driver Mode Selector Attributes
Affected”. Track Mode (V-Series Only)
Use when maximum vehicle handling
is desired. For use when driving on a
closed race course or drag strip.
When selected, the Track Mode
indicator will display.
When in Track Mode, the automatic
transmission and steering will
function similar to Sport Mode. The
accelerator pedal is adjusted to give
maximum control during the highest
level of spirited driving. The Magnetic
Ride Control will be set to the
optimum level for vehicle
responsiveness. Performance Traction
Management (PTM) can be accessed
through this mode. See
“Performance
Traction Management ”in Competitive
Driving Mode 0191.
For further details on Track Mode, see
“Driver Mode Selector Attributes
Affected”. My Mode
My Mode is used to personalize
everyday driving. This mode is
designed to allow the driver to
configure vehicle sub-systems to their
own preference for city or normal
driving.
Through the center display, the
following vehicle sub-systems may be
available for customization in
this mode.

Driver Mode Customization
The vehicle is equipped to modify
following vehicle settings based on
vehicle content. Through the
center-stack, see “Driving Mode”under
Vehicle Personalization 0124 to
customize and personalize My Mode
and/or V-Mode.
Engine Sound
Engine sound adjusts the volume of
engine noise. Setting ranges from
quietest to loudest volume as you
move from stealth through Track.
–Stealth, Tour, Sport, Track Steering
This setting adjusts the effort required
to turn the steering wheel. The
steering wheel offers better feedback
but requires more effort as you move
from Tour to Track.
–Tour, Sport, Track
Suspension
This setting adjusts the firmness of
the suspension in the vehicle.
Suspension adjust stiffness of the
shocks and / or springs. The ride is
more comfortable at lower settings
and is stiffer at higher settings for
better control.
–Tour, Sport, Track
Powertrain
This setting adjusts the throttle
response, gear shifting and engine
performance. An increased throttle
response enhances the acceleration
feel as you move towards track, but
with a comfort trade-off due to more
aggressive gear shifting.

Competitive Driving Mode
To select this optional handling mode,
press
gquickly two times and the DIC
will display COMPETITIVE MODE ON.
While in the Competitive Driving
Mode, the traction off light
iand
StabiliTrak/ESC 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
(V-Series Only)” later in this section.
Adjust your driving accordingly. Press
gagain, or turn the ignition to
ACC/ACCESSORY and restart the
vehicle, to turn TCS back on. The
traction off light
iand StabiliTrak/
ESC OFF light
gwill go out in the
instrument cluster.
Caution
When traction control is turned off,
or Competitive Driving Mode is
active, it is possible to lose traction.
Performance Traction
Management (PTM) (if equipped)
PTM integrates the TCS, StabiliTrak/
ESC, and Magnetic 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 in Track. Then quickly press
gon the center console two times.
PERF TRAC 1 —WET ACTIVE
HANDLING ON displays in the DIC.
To experience the performance benefit
of this system, after entering a curve
and at the point where normal
acceleration occurs, fully press the
accelerator pedal. The PTM system
will modify the level of engine power
for a smooth and consistent
corner exit.
