cluster, seeInstrument Cluster 079 >
Options > Display themes.
Throttle Progression
Adjusts throttle sensitivity by selecting how
quickly or slowly the throttle reacts to
input.
Throttle Progression is a preset of
Powertrain and cannot be modified or
changed independently.
Transmission Shift Operation
Basic:
.Transmission upshifts and downshifts are
selected based on vehicle speed and
accelerator position to optimize comfort
and fuel economy during mild driving
conditions.
Driver Influenced Gear Selection:
.Aggressive driving will influence both the
upshift and downshift points in all modes.
When engaged, the Performance
Transmission Active light displays. See
Performance Transmission Active 089. When Performance Transmission is
activated from a standstill, by selecting
PTM Race 1 or Race 2, the transmission
shift map is in the most aggressive state
where upshifts are only achieved at high
revolutions per minute (rpm), downshifts
happen early, and the lowest gear is
selected for cornering. Transmission
behavior will transition to a level
appropriate to the current driving
behavior after a short period of time.
If PTM Race 1 or Race 2 are not selected,
the Performance Transmission Active
behavior still activates automatically after
a sustained period of performance driving
is detected. See
“Performance Traction
Management (PTM)” later on in this
section.
.Criteria which have influence are: driving
mode, accelerator, brakes, lateral, and
longitudinal loading.
.Changes in gear selection behavior due to
aggressive driving can include:
‐ Downshifting early with higher rpm’s
during aggressive braking (i.e. entering
a corner)
‐ Altering upshifts while experiencing
lateral acceleration ‐
Not upshifting when the accelerator is
released to avoid unnecessary shifts if
the accelerator is re-applied
‐ Recognizing sporty driving and
anticipate upcoming corners with the
appropriate gear selection entering and
exiting
.Driver Modes
‐Driver influenced changes are effective
in all driving modes, however the
aggressiveness of the transmission
response will increase between Tour,
Sport, and Track Modes respectively.
Active Fuel Management (Engine Cylinder
Shuts Off)
.Normal with Dual Clutch Transmission:
The engine uses 8-cylinder mode when
accelerating, but changes to 4-cylinder
mode when coasting.
Active Fuel Management is a preset of
Powertrain and cannot be modified or
changed independently.

Engine Sound
Caution
Using a stealth engine sound setting
during spirited driving will cause the
exhaust system to overheat and damage
the variable exhaust valves. Do not use
this setting when auto-crossing or driving
on high speed tracks.
If available, engine sound settings change
when the variable exhaust valves open.
Steering (Assist Effort)
Adjusts from a lighter steering feel to
reduced assist for more steering feel.
Magnetic Ride Control
If equipped, this feature adjusts the shock
dampening firmness based on driving
conditions to improve comfort and
performance.
Drive Mode Customization
The vehicle is equipped to modify the
following vehicle settings base on vehicle
content. Through the infotainment home
screen, select Settings > Vehicle > “Drive
Mode Customization” to customize and
personalize My Mode and/or Z-Mode. Engine Sound
Engine Sound adjusts the volume of engine
noise. Setting range 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 Engine/Shift
This setting adjusts the throttle response,
gear shifting and engine performance. An
increased throttle response enhances the
acceleration feel as you move toward Track,
but with a comfort trade-off due to more
aggressive gear shifting.
.Weather, Tour, Sport, Track
Brake Feel
This setting adjusts the brake pedal
response. Settings range from a slower
response for more comfortable driving to
the quickest response for quicker
deceleration. Track allows for improved
pedal precision at higher decelerations for
high performance driving.

Front Lift System
A two-position lift actuator (one per damper)
with 35 mm (1.5 in) of stroke will
hydraulically raise the front of the vehicle to
provide approximately 50 mm (2 in) of
increased clearance in approximately
three seconds (height and time will vary by
vehicle). The Front Lift System will allow
you to lift the front of the vehicle to enter a
driveway, driving over curbs, speed bumps
or onto ramps or a trailer.
To use the Front Lift System, press the
button on the center console to raise or
lower the vehicle. This feature can be
operated at speeds up to 38 km/h (24 mph)
when the engine is running. The system
functions based on the vehicle’s state or
operating mode:
.The system will not raise up when the
doors or underhood storage compartment
is open.
.The system can be raised or lowered by
the pushbutton, when the vehicle is in
RUN or in accessory mode.
.If the vehicle is in the raised position and
is driven at speeds above 38 km/h
(24 mph), it will automatically lower.
.If the vehicle is turned off, it will
automatically lower.
.If a vehicle door is opened during
lowering, the movement will pause for
15 seconds then continue to lower, but at
a slower rate.
If equipped, the front height can be raised
automatically using GPS navigation in the
vehicle. The vehicle will automatically lift in
up to 1,000 programmable locations. Once
the button is pushed, a notification will
appear on the Driver Information Center
(DIC) and prompt the driver if they would
like to “Remember” the location. The driver
can select this function through the steering
wheel controls, see Steering Wheel Controls
0 111.
The driver can also delete stored locations
for the automatic lift.
If the vehicle is raised automatically using
GPS, it will automatically lower once the
vehicle is located about 60 meters (197 feet)
from the programmed location. To disable
this function, turn off the GPS location via
the vehicle Customization Settings. The Front
Lift System will now only operate using the
pushbutton command, and the “Auto Lift
Location Remembered” confirmation
message will not display.

Competitive Driving Mode
If equipped, Competitive Driving Mode,
Performance Traction Management (PTM),
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 a race track. Drivers
who prefer to allow the system to have
more control of the engine, brakes, and
suspension are advised to turn on the
normal traction control and StabiliTrak/
Electronic Stability Control (ESC) systems on.
Competitive Driving Mode
Competitive Driving Mode allows full engine
power while StabiliTrak/ESC helps maintain
directional control of the vehicle by selective
brake application. In this mode, the Traction
Control System (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.
These lights are on when the vehicle is in
the Competitive Driving Mode.
To select this optional handling mode, the
vehicle mode must be Sport or Track (if
equipped with PTM, then Competitive
Driving Mode is only available in Sport).
Then quickly press
@on the center console
