For more information on the display themes
of the Drive modes on the instrument
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.

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

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.

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
two times. ESC COMPETITIVE MODE displays
in the Driver Information Center (DIC).

Passing Another Vehicle While Using Cruise
Control
Use the accelerator pedal to increase the
vehicle speed. When you take your foot off
the pedal, the vehicle will slow down to the
previously set cruise speed.
While pressing the accelerator pedal or
shortly following the release to override
cruise control, briefly pressing SET–will
result in cruise set to the current vehicle
speed.
Using Cruise Control on Hills
How well the cruise control works on hills
depends upon the vehicle speed, load, and
the steepness of the hills. When going up
steep hills, you may have to step on the
accelerator pedal to maintain your speed.
When going downhill, you may have to
brake or shift to a lower gear to keep your
speed down. If the brake pedal is applied,
cruise control will disengage.
Cruise Control in Manual Paddle Shift Gear
Selection
When the vehicle is in M (Manual Mode)
and the manual paddle shift controls are not
being used, cruise control operates in the
same manner as D (Drive). When the vehicle is in M (Manual Mode)
and the manual paddle shift controls are
being used, cruise control operates as
follows:
.If cruise control is active and a gear is
selected with the manual paddle shift
controls, the vehicle speed is maintained
in the driver selected gear and will not
automatically upshift or downshift the
transmission while the driver gear
selection is active.
.If driving in hilly terrain, cruise control
may not be able to maintain vehicle
speed if an upshift or downshift is not
selected by the driver. While driving on
hilly terrain and cruise control is active
with a manual paddle shift gear selection,
the driver must select the proper gear for
the terrain or select D (Drive) on the
shifter for full automatic transmission
operation.
Ending Cruise Control
.Step lightly on the brake pedal.
.Shift the transmission to N (Neutral).
.Press*.
.To turn off cruise control, press1. Erasing Speed Memory
The cruise control set speed is erased from
memory if
1is pressed or if the ignition is
turned off.
Driver Assistance Systems
This vehicle may have features that work
together to help avoid crashes or reduce
crash damage while driving, backing, and
parking. Read this entire section before
using these systems.
{Warning
Do not rely on the Driver Assistance
Systems. These systems do not replace
the need for paying attention and driving
safely. You may not hear or see alerts or
warnings provided by these systems.
Failure to use proper care when driving
may result in injury, death, or vehicle
damage. See Defensive Driving 0170.
Under many conditions, these systems
will not:
.Detect children, pedestrians, bicyclists,
or animals. (Continued)

Driving and Operating 225
Park Assist
With RPA, as the vehicle backs up at speeds
of less than 8 km/h (5 mph), the sensors on
the rear bumper may detect objects up to
2.5 m (8 ft) behind the vehicle within a zone
25 cm (10 in) high off the ground and below
bumper level. These detection distances may
be shorter during warmer or humid weather.
Blocked sensors will not detect objects and
can also cause false detections. Keep the
sensors clean of mud, dirt, snow, ice, and
slush; and clean sensors after a car wash in
freezing temperatures.
{Warning
The Park Assist system does not detect
children, pedestrians, bicyclists, animals,
or objects located below the bumper or
that are too close or too far from the
vehicle. It is not available at speeds
greater than 8 km/h (5 mph). To prevent
injury, death, or vehicle damage, even
with Park Assist, always check the area
around the vehicle and check all mirrors
before moving forward or backing.
The instrument cluster may have a Park
Assist display with bars that show“distance
to object” and object location information
for RPA. As the object gets closer, more bars
light up and the bars change color from
yellow to amber to red.
When an object is first detected in the rear,
one beep will be heard from the rear. When
an object is very close (<0.6 m (2 ft) in the
vehicle rear), five beeps will sound from
the rear.
Rear Cross Traffic Alert (RCTA)
System
If equipped, RCTA displays a red warning
triangle with a left or right pointing arrow
on the RVC screen to warn of traffic coming
from the left or right. This system detects
objects coming from up to 20 m (65 ft) from
the left or right side of the rear of the vehicle. When an object is detected, three
beeps sound from the left or right,
depending on the direction of the detected
vehicle.
RCTA can be turned on or off through
vehicle settings. To view available settings
from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems.
Side Blind Zone Alert (SBZA)
If equipped, the Side Blind Zone Alert (SBZA)
system is a lane-changing aid that assists
drivers with avoiding crashes that occur with
moving vehicles in the side blind zone,
or blind spot areas. The SBZA warning
display will light up in the corresponding
outside side mirror and will flash if the turn
signal in corresponding side is on.
{Warning
SBZA does not alert the driver to vehicles
rapidly approaching outside of the side
blind zones, pedestrians, bicyclists,
or animals. It may not provide alerts
when changing lanes under all driving
conditions. Failure to use proper care
when changing lanes may result in injury,

Warning (Continued)
death, or vehicle damage. Before making
a lane change, always check mirrors,
glance over your shoulder, and use the
turn signals.
SBZA Detection Zones
The SBZA sensor covers a zone
approximately one lane over from both
sides of the vehicle, or approximately
3.5 m (11 ft). The height of the zone is
approximately between 0.5 m (1.5 ft) and
2 m (6 ft) off the ground. This zone starts at
approximately the middle of the vehicle and
goes back 5 m (16 ft).
How the System Works
The SBZA symbol lights up in the side
mirrors when the system detects a moving
vehicle in the next lane over that is in the
side blind zone. This indicates it may be
unsafe to change lanes. Before making a
lane change, check the SBZA display, check
mirrors, glance over your shoulder, and use
the turn signals.
Left Side Mirror DisplayRight Side Mirror Display
When the vehicle is started, both outside
mirror SBZA displays will briefly come on to
indicate the system is operating. When the
vehicle is in a forward gear, the left- or
right-side mirror display will light up if a
moving vehicle is detected in that blind
zone. If the turn signal is activated in the
same direction as a detected vehicle, this
display will flash as an extra warning not to
change lanes. SBZA can be disabled through vehicle
personalization. To view available settings
from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems. If SBZA is disabled by the driver,
the SBZA mirror displays will not light up.
When the System Does Not Seem to
Work Properly
SBZA displays may not come on when
passing a vehicle quickly, for a stopped
vehicle. SBZA may alert to objects attached
to the vehicle, such as a bicycle, or object
extending out to either side of the vehicle.
This is normal system operation; the vehicle
does not need service.
SBZA may not always alert the driver to
vehicles in the side blind zone, especially in
wet conditions. The system does not need
to be serviced. The system may light up due
to guardrails, signs, trees, shrubs, and other
non-moving objects. This is normal system
operation; the vehicle does not need service.
SBZA may not operate when the SBZA
sensors in the left or right corners of the
rear bumper are covered with mud, dirt,
snow, ice, or slush, or in heavy rainstorms.

DIC still displays the system unavailable
message after cleaning both sides of the
vehicle toward the rear corners of the
vehicle, see your dealer.
If the SBZA displays do not light up when
vehicles are in the blind zone and the
system is clean, the system may need
service. Take the vehicle to your dealer.
When SBZA is disabled for any reason other
than the driver turning it off, the Side Blind
Zone Alert On option will not be available
on the personalization menu.
