drag strip use. See “Custom Launch
Control ”in Track Events and
Competitive Driving (V-Series and
V-Series Blackwing) 0213.
Launch Control
If equipped, Launch Control is
available within Competitive Driving
Mode and PTM to allow high levels of
vehicle acceleration in a straight line.
Launch Control is a form of traction
control that manages tire spin while

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-15283641) -
2022 - CRC - 10/12/21
266 DRIVING AND OPERATING
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 is
selected or any of the PTM modes
are selected. The traction off light
comes on in the instrument cluster
and the appropriate DIC message
displays.
.The vehicle is not moving.
.The steering wheel is pointing
straight.
Automatic Transmissions
.The brake pedal is firmly pressed to
the floor, equivalent to a panic
brake event.
.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
reapply the accelerator to wide open
throttle.Launch Control will initially limit
engine speed as you rapidly apply the
accelerator pedal to wide open
throttle. Allow the engine rpm to
stabilize. A smooth, quick release of
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 0264 and
Maintenance Schedule 0408.
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.

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 following gap. The range of selectable
gaps may not be appropriate for all
drivers and driving conditions.
Changing the gap setting
automatically changes the alert timing
sensitivity (Far, Medium, or Near) for
the Forward Collision Alert (FCA)
feature. See
Forward Collision Alert
(FCA) System 0301.
Courtesy Gap (If Equipped with
Super Cruise)
Press and Hold
[on the steering
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.

ignition is turned off.
Weather Conditions Affecting ACC
System operation may be limited
under snow, heavy rain, or road spray
conditions.
Accessory Installations and Vehicle
Modifications
Do not install or place any object
around the front camera windshield
area that would obstruct the front
camera view.
Do not install objects on top of the
vehicle that overhang and obstruct the
front camera, such as a canoe, kayak,
or other items.
Do not modify the hood, headlamps,
or fog lamps, as this may limit the
camera’s ability to detect an object.
Cleaning the Sensing System
The camera sensor on the windshield
behind the rearview mirror and the
radar sensors on the front of the
vehicle can become blocked by snow, ice, dirt, or mud. These areas need to
be cleaned for ACC to operate
properly.
If ACC will not operate, regular Cruise
Control may be available. See
“Switching Between ACC and Regular
Cruise Control
”previously in this
section. Always consider driving
conditions before using either cruise
control system.
For cleaning instructions, see

System operation may also be limited
under snow, heavy rain, or road spray
conditions.
Super Cruise
If equipped, Super Cruise can steer to
maintain lane position under certain
conditions on Super Cruise-enabled
roads that are separated from
opposing traffic.
Super Cruise can also steer to perform
a lane change under certain
conditions on Super Cruise-enabled
roads. A lane change can be initiated by the
driver using the turn signal lever. The
Super Cruise System may initiate a
lane change maneuver in the
following scenarios:
.To pass slower traffic
.When the current lane is ending
ahead
.To return to the initial lane
See “Super Cruise Lane Change ”later
in this section and Turn and
Lane-Change Signals 0131.
{Warning
Super Cruise can only assist to
maintain lane position, or steer to
change lanes, when driving on
compatible roads. You must
supervise the driving task and
