Driver Influenced Gear Selection:
.Aggressive driving will influence both the
upshift and downshift points in all modes.
.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)
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 center stack, under
Vehicle Settings, select
“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.

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 toward Track,
but with a comfort trade-off due to more
aggressive gear shifting.
.Weather, Tour, Sport, Track
Brake Response:
This setting adjusts the brake pedal
response. Settings range from a slower
response for more comfortable driving to
the quickest response for quicker
deceleration. Brake pedal travel decreases
and caliper pressure increases as you move
from Tour to Sport. Track allows for
improved pedal precision at higher
decelerations for high performance driving.
.Tour, Sport, Track Performance Traction Management (PTM):
To activate PTM through Z-Mode, configure
Z-Mode to the desired PTM state in the
center stack (Vehicle>Settings>Drive Mode
Customization>Z-Mode). Press the Z-Mode
button once to activate Z-Mode. When PTM
is configured on, a message will appear in
the Driver Information Center (DIC)
“Z-Mode
Active —Press Again for PTM On —ESC
May be Disabled”.
To confirm, and enter PTM, press the
Z-Mode button again. The PTM state can
now be modified using the mode knob or
changing the Z Mode setting in the center
stack. Both the Z Mode and PTM indicators
will be displayed.
To cancel, press the center dismiss button
on the steering wheel (Z Mode remains
active). Selecting PTM states may modify
other Z Mode customization options.

Display:
This setting adjusts the cluster display
theme (this setting is only configured
through the cluster using the steering wheel
controls).
.Tour, Sport, Track, Weather (and any
informational tiles set-up).
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)

Launch Control (Sport and Track
Mode Only)
A Launch Control feature is available, within
Competitive Driving Mode or PTM, on all
vehicles to allow the driver to achieve high
levels of vehicle acceleration in a straight
line. Launch Control is a form of TCS that
manages tire spin, and transmissions clutch,
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 or any of the
PTM Modes are selected (if equipped).
.The vehicle is not moving.
.The wheels and steering wheel are
pointing straight.
Launching the Vehicle
.Ensure the vehicle is in Competitive
Driving Mode or any of the PTM modes.
.The brake pedal must be firmly pressed
to the floor, equivalent to a panic brake
event.
.While maintaining the brake pedal, 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.)
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’s to stabilize.
A smooth, quick release of the brake pedal,
while maintaining the fully pressed
accelerator pedal, will manage tire slip and
transmissions clutch. After the vehicle is
launched, the system continues in
Competitive Driving Mode or PTM.
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.
Caution
The new vehicle break-in period should be
completed before using the launch
control feature, otherwise performance
will be limited and damage may occur to
the powertrain/engine. See New Vehicle
Break-In 0192.

218 Driving and Operating
Limited-Slip Differential
(Without Z51)
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. See
Competitive Driving Mode0215 and
Maintenance Schedule 0293.
Limited-Slip Differential (With Z51)
The Electronic Limited-Slip Differential (eLSD)
is a hydraulically actuated clutch system
inside the transaxle. It can infinitely vary
the clutch engagement between 0 and
2250 N*m (1659 lb-ft) of breakaway torque
between the rear wheels. When necessary it
responds from open to full engagement in
fractions of a second. Smaller clutch
adjustments happen even faster.
The eLSD:
.Uses the vehicle sensors and driver inputs
to determine the optimum amount of
clutch engagement for the conditions.
.Improves traction while cornering by
changing the engagement to achieve a
balance between directional control and
acceleration.
.Provides optimal engagement for
high-speed control and stability without
affecting precise steering and turn-in.
.Improves vehicle stability during spirited
driving and evasive maneuvers. It is fully
integrated with the Active Handling and
Performance Traction Management (PTM)
systems (if equipped).
There are unique calibrations based on the
Traction Control System (TCS) setting. eLSD
modes change automatically when the
traction control button is pressed. No unique
input from the driver is required.
.Mode 1 is the standard mode when the
vehicle is started. It provides a touring
calibration with an emphasis on vehicle
stability. Mode 1 is also used in PTM
Wet mode.
.Mode 2 is engaged when both TCS and
StabiliTrak are turned off. This calibration
provides more nimble corner turn-in, and
is biased for better traction out of
corners.
.Mode 3 is engaged when PTM is engaged
in Dry, Sport 1 & 2, and Race modes. This
is a nimble calibration with similar
functionality as eLSD Mode 2, however, it
is integrated to work with PTM.
.Mode 4 is engaged when TCS is selected
off, but StabiliTrak remains on. Vehicle
stability is still the priority, while allowing
for optimized traction out of corners.
Cruise Control
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).
{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 (Continued)
