the brake pedal, while maintaining the
fully pressed accelerator pedal, will
manage wheel slip.
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 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/
Electronic Stability Control (ESC).
For vehicles with eLSD, driven under
severe conditions, the rear axle fluid
should be changed. See Competitive
Driving Mode 0247 and
Maintenance Schedule 0383.
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 Traction Control/StabiliTrak/
Electronic Stability Control (ESC)
system begins to limit wheel spin
while using cruise control, the cruise
control automatically disengages. See
Traction Control/Electronic Stability
Control
0240. If a collision alert
occurs when cruise control is
activated, cruise control is disengaged.
See Forward Collision Alert (FCA)
System 0285. When road conditions
allow cruise control to be safely used,
it can be turned back on.
Cruise control will disengage if either
TCS or StabiliTrak/ESC is turned off.
If the brakes are applied, cruise
control disengages.

moving in the same direction. If no
vehicle is detected in your path, ACC
works like regular cruise control. ACC
uses camera and radar sensors. See
Radio Frequency Statement0410.
If a vehicle is detected in your path,
ACC can speed up the vehicle or apply
limited, moderate braking to maintain
the selected following gap. To
disengage ACC, apply the brake. If the
Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) system activates while ACC is
engaged, ACC may automatically
disengage. See Traction Control/
Electronic Stability Control 0240. When
road conditions allow ACC to be safely
used, ACC can be turned back on. ACC
will not engage if the TCS or
StabiliTrak/ESC electronic stability
control system is disabled.
ACC can reduce the need for you to
frequently brake and accelerate,
especially when used on expressways,
freeways, and interstate highways.
When used on other roads, you may
need to take over the control of
braking or acceleration more often.{Warning
ACC has limited braking ability and
may not have time to slow the
vehicle down enough to avoid a
collision with another vehicle you
are following. This can occur when
vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver” in this section.
Complete attention is always
required while driving and you
should be ready to take action and
apply the brakes. See Defensive
Driving 0210.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
.On winding and hilly roads or
when the sensors are blocked by
snow, ice, or dirt. The system
(Continued)
Warning (Continued)
may not detect a vehicle ahead.
Keep the entire front of the
vehicle clean.
.Visibility is low, such as in fog,
rain, or snow conditions. ACC
performance is limited under
these conditions.
.On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.
J:Press to turn the system on or
off. The indicator turns white on the
instrument cluster when ACC is
turned on.

The set speed can also be increased
while the vehicle is stopped.
.If stopped with the brake applied,
press RES+ until the desired set
speed is displayed.
.If ACC is holding the vehicle at a
stop and there is another vehicle
directly ahead, pressing RES+ will
increase the set speed.
.Pressing RES+ when there is no
longer a vehicle ahead or the vehicle
ahead is pulling away and the brake
is not applied will cause the ACC to
resume.
When it is determined there is no
vehicle ahead or the vehicle ahead is
beyond the selected following gap,
then the vehicle speed will increase to
the set speed.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster (Base
Level) 094 or
Instrument Cluster (Uplevel) 096. The
increment value used depends on the
units displayed. Reducing Speed While ACC Is at a
Set Speed
If ACC is already activated, do one of
the following:
.Use the brake to get to the desired
lower speed. Release the brake and
press SET−. The vehicle will now
cruise at the lower speed.
.Press and hold SET−
until the
desired lower speed is displayed,
then release it.
.To decrease speed in smaller
increments, press SET− to the first
detent. For each press, the vehicle
goes about 1 km/h (1 mph) slower.
.To decrease speed in larger
increments, press or hold SET− to
the second detent. For each press,
the vehicle speed decreases to the
next 5 km/h (5 mph) mark on the
speedometer.
The set speed can also be decreased
while the vehicle is stopped.
.To decrease speed while the vehicle
is stopped, press SET− until the
desired set speed is displayed. Selecting the Follow Distance Gap
When a slower moving vehicle is
detected ahead within the selected
following gap, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected.
Press
[on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap setting
displays briefly on the instrument
cluster and the HUD (if equipped).
Subsequent presses cycle the gap
button through three settings: Far,
Medium, or Near. The gap setting will
be maintained until it is changed.
Since each gap setting corresponds to
a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further
back your vehicle will follow a vehicle
detected ahead. Consider traffic and
weather conditions when selecting the

wheel when vehicle is moving to
temporarily increase the gap with the
vehicle ahead to allow for merging
traffic.
Press and Hold
[when stopped to
cancel ACC from resuming
automatically (if the stop is brief) and
remain stationary. This can be used to
allow traffic to merge between you
and the vehicle ahead.
Press RES+ or the accelerator pedal to
resume ACC. Following distance gap
will return to the original selection
after hold. Alerting the Driver
If ACC is engaged, driver action may
be required when ACC cannot apply
sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, the
collision alert symbol will flash on the
windshield. Either eight beeps will
sound from the front, or both sides of
the Safety Alert Seat will pulse five
times. See
“Collision/Detection
Systems” underVehicle Personalization
0 123.
See Defensive Driving 0210. Approaching and Following a
VehicleThe vehicle ahead indicator is in the
instrument cluster and HUD display,
if equipped.
The vehicle ahead indicator only
displays when a vehicle is detected in
your vehicle’s path moving in the
same direction.
If this symbol is not displaying, ACC
will not respond to or brake to
vehicles ahead.
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow a detected vehicle ahead at the
selected follow gap. The vehicle speed
increases or decreases to follow a
detected vehicle in front of your
vehicle when that vehicle is traveling
slower than your vehicle set speed.
It may apply limited braking,
if necessary. When braking is active,

so, your hands can be taken off the
steering wheel.
Always pay attention to the road and
the operation of the vehicle. Always
monitor and be attentive of
surrounding traffic, including vehicles
that may cross the road in front of
your vehicle.
Super Cruise steering can be
overridden with manual steering at
any time. When Super Cruise is
engaged, always be prepared to take
immediate action
—including
steering, accelerating, and braking
quickly, if necessary.
Steering Manually and Changing
Lanes
The vehicle can always be manually
steered, even with Super Cruise
engaged; for example, when changing
lanes. When the steering wheel is moved
manually, the steering wheel light bar
pulses blue and
^on the instrument
cluster turns blue to indicate Super
Cruise is not steering the vehicle.
