Super Cruise Lane Change
Super Cruise can steer to perform a single
lane change under certain conditions when
requested by the driver or initiated by the
Super Cruise System.
On Demand Lane Changes
To request a lane change:1. Verify the lane next to your vehicle is clear and conditions are safe to make a
lane change.
2. Use the turn signal lever to activate the turn signal in the direction of the desired
lane change.
3. Return the turn signal lever to the neutral position after the lane change.
See Turn and Lane-Change Signals 0143.
4. To cancel a lane change, return the turn signal lever to the neutral position, move
the lever in the opposite direction of the
lane change, or steer manually at
any time. Automatic Lane Changes
If equipped, the Super Cruise System may
initiate a single lane change when enabled
through vehicle settings under following
conditions:
.The Super Cruise System may initiate a
lane change to the left to pass a slower
moving vehicle ahead and a subsequent
lane change to right to return to your
original lane.
.The Super Cruise System may initiate an
automatic lane change to left or right
when the current lane is ending ahead.
.To cancel a Super Cruise automatic lane
change, move the turn signal lever or
steer manually at any time.
.Super Cruise may initiate an automatic
lane change to left or right when a
slower moving vehicle is detected in the
adjacent ending lane to provide space for
merging vehicle.
If Super Cruise detects that traffic is clear,
Super Cruise will steer the vehicle to
perform the lane change. A message appears
on the Driver Information Center (DIC)
during the lane change to provide more
information on the status of the lane
change.
Super Cruise Lane Change functionality is
only available on Super Cruise capable
Divided Roads.
Super Cruise Lane Change functionality is
not available when a construction zone is
detected.
Super Cruise Lane Change may be disabled
when a trailer or other accessories (e.g. bike
rack, cargo tray, etc.) are detected. Do not
use Super Cruise Lane Change when towing
a trailer.
The Super Cruise Lane Change feature can
be customized to be Off, On Demand Lane
Change, or On Demand Lane Change &

{Warning
Super Cruise Lane Change may not detect
a vehicle in an adjacent lane. Always
supervise the driving task and monitor
traffic conditions when using the Super
Cruise Lane Change feature. Only request
a lane change when traffic conditions are
safe for a lane change, and always be
ready to manually steer the vehicle. See
“Steering Manually and Changing Lanes”
listed previously in this section.
Super Cruise Navigation Route Follow Using
In-Vehicle Google Maps
If equipped, when an active route is selected
using in-vehicle Google Maps, on Super
Cruise-enabled roads when Super Cruise is
active, Super Cruise may take the following
actions to follow the route:
.Initiate an automatic lane change to left
or right.
.Select the direction of travel at a lane
split.
.Maintain the current lane of travel when
following a slower moving vehicle. The driver must always remain prepared to
take control of the vehicle to follow the
route. In some scenarios Super Cruise may
not perform the required lane change.
Super Cruise will not perform the required
lane change if Automatic Lane Change is
unavailable or disabled.
Take Over Alert
{Warning
Super Cruise will not maintain the
vehicle’s speed while the steering wheel
light bar is flashing red. If the steering
wheel light bar flashes red, immediately
resume manual steering to prevent
serious injury or death. If you do not

Super Cruise is a driver assistance system
and cannot accurately detect or predict
all situations. Super Cruise is not a crash
avoidance system. To prevent serious
injury or death, you must supervise the
driving task and monitor the road
conditions. You may need to respond to
traffic events by steering, braking,
or accelerating. See
Defensive Driving
0 183. Super Cruise also cannot determine
whether you are awake, asleep, impaired,
or properly focused on safe driving. The
vehicle could crash into other vehicles,
drive out of the lane, or drive off the
road. Complete attention is always
required while driving, even while using
Super Cruise. Be prepared to take over
steering or apply the brakes at any time.

of the trailer.
.The Trailer Length Indicator Overlays
will appear closer and possibly overlap
with the trailer.
Park Assist
With Front and Rear Park Assist, as the
vehicle moves at speeds of less than 8 km/h
(5 mph) the sensors on the bumpers may
detect objects up to 1.2 m (4 ft) in front and
1.8 m (6 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 the Front and Rear Park Assist system.
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,
or both sides of the Safety Alert Seat will
pulse two times. When an object is very
close —<0.4 m (1.5 ft) in the vehicle rear or
<0.3 m (1 ft) in the vehicle front —a
continuous beep will sound from the rear or
front depending on object location, or both
sides of the Safety Alert Seat will pulse five
times. Beeps for FPA are higher pitched than
for RPA.

Assist (LKA), Blind Zone Steering Assist
(BZSA), Lane Change Alert (LCA), Automatic
Emergency Braking (AEB), Intersection
Automatic Emergency Braking (I-AEB), and/or
the Front Pedestrian Braking (FPB) System
can help to avoid a crash or reduce crash
damage.
Forward Collision Alert (FCA)
System
If equipped, the FCA system may help to
avoid or reduce the harm caused by
front-end crashes. When approaching a
vehicle ahead too quickly, FCA provides a
red flashing alert on the windshield and
rapidly beeps or pulses the drivers seat. FCA
also lights an amber visual alert if following
another vehicle much too closely.
FCA detects vehicles within a distance of
approximately 60 m (197 ft) and operates at
speeds above 8 km/h (5 mph).
{Warning
FCA is a warning system and does not
apply the brakes. When approaching a
slower-moving or stopped vehicle ahead
too rapidly, or when following a vehicle
too closely, FCA may not provide a
warning with enough time to help avoid
a crash. It also may not provide any
warning at all. FCA does not warn of
pedestrians, animals, signs, guardrails,
bridges, construction barrels, or other

0 183.
FCA can be disabled. To view available
settings from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems.
Detecting the Vehicle Ahead
FCA warnings will not occur unless the FCA
system detects a vehicle ahead. When a
vehicle is detected, the vehicle ahead
indicator will display green. Vehicles may
not be detected on curves, highway exit
ramps, or hills, due to poor visibility; or if a
vehicle ahead is partially blocked by
pedestrians or other objects. FCA will not
detect another vehicle ahead until it is
completely in the driving lane.

262 Driving and Operating
{Warning
FCA does not provide a warning to help
avoid a crash, unless it detects a vehicle.
FCA may not detect a vehicle ahead if
the FCA sensor is blocked by dirt, snow,
or ice, or if the windshield is damaged.
It may also not detect a vehicle on
winding or hilly roads, or in conditions
that can limit visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in proper
condition. Keep the windshield,
headlamps, and FCA sensors clean and in
good repair.
Collision Alert
With Head-Up Display
Without Head-Up Display
When your vehicle approaches another
detected vehicle too rapidly, the red FCA
display will flash on the windshield. Also,
eight rapid high-pitched beeps will sound
from the front, or both sides of the Safety
Alert Seat will pulse five times. When this
Collision Alert occurs, the brake system may
prepare for driver braking to occur more
rapidly which can cause a brief, mild
deceleration. Continue to apply the brake
pedal as needed.
Tailgating Alert
The vehicle ahead indicator will display
amber when you are following a vehicle
ahead much too closely.
Selecting the Alert Timing
The Collision Alert control is on the steering
wheel. Press
[to set the FCA timing to
Far, Medium, or Near. The first button press
shows the current setting on the DIC.
Additional button presses will change this
setting. The chosen setting will remain until
it is changed and will affect the timing of
both the Collision Alert and the Tailgating
Alert features. The timing of both alerts will
vary based on vehicle speed. The faster the
vehicle speed, the farther away the alert will
occur. Consider traffic and weather
conditions when selecting the alert timing.
The range of selectable alert timings may
not be appropriate for all drivers and driving
conditions.
If your vehicle is equipped with Adaptive
Cruise Control (ACC), changing the FCA
timing setting automatically changes the
following gap setting (Far, Medium,
or Near).

same direction as a detected vehicle, this
display will flash as an extra warning not to
change lanes.
LCA can be disabled through vehicle
personalization.To view available settings
from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems. If LCA is disabled by the driver, the
LCA mirror displays will not light up.
When the System Does Not Seem to
Work Properly
The LCA system requires some driving for
the system to calibrate to maximum
performance. This calibration may occur
more quickly if the vehicle is driven on a
straight highway road with traffic and
roadside objects (e.g., guardrails, barriers).
LCA displays may not come on when
passing a vehicle quickly or for a stopped
vehicle. LCA may alert to objects attached to
the vehicle, such as a bicycle, or object
extending out to either side of the vehicle.
Attached objects may also interfere with the
detection of vehicles. This is normal system
operation; the vehicle does not need service.LCA may not always alert the driver to
vehicles in the next lane over, especially in
wet conditions or when driving on sharp
curves. 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.
LCA may not operate when the LCA sensors
in the left or right corners of the rear
bumper are covered with mud, dirt, snow,
ice, or slush, or in heavy rainstorms. For
cleaning instructions, see "Washing the
Vehicle" under
Exterior Care0379. If the 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 LCA displays do not light up when
moving vehicles are in the side blind zone or
rapidly approaching this zone and the
system is clean, the system may need
service. Take the vehicle to your dealer.
Driving with a Trailer
If equipped with Lane Change Alert (LCA),
the LCA detection zones that extend back
from the side of the vehicle do not move
further back when a trailer is towed. Use caution while changing lanes when
towing a trailer.
Bicycle Detection
If equipped, the system may detect a
bicyclist approaching from the side or rear
of the vehicle.
If this occurs, a chime will sound in the
direction of the detection, and the Safety
Alert Seat will pulse if enabled through
vehicle settings. To view available settings
from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems.
Bicyclist Detection is available when the
vehicle is in D (Drive), P (Park), and for a
short time after the vehicle is turned off.
If the vehicle detects a bicyclist when it is
off, a DIC message may display and alert to
the direction of the detection. In some
cases, an Unavailable message may display.
This is normal and does not mean that the
system is broken.
Detection Zones
When the vehicle is in P (Park) or is turned
off, a bicyclist can be detected 11 m (36 ft)
behind the vehicle or 10 m (33 ft) to the
side of the vehicle.

Navigation System Traffic Sign Detection
The currently displayed sign can either
originate from sign detection using the
camera, or from the navigation system map
data. If the currently displayed sign
originates from map data and the map
information changes, a new sign will be
displayed. This may lead to detection of a
new sign although no sign on the road may
have been passed. If the map data is
unavailable, Traffic Sign Assistant will turn
off automatically.
Limitations
Traffic sign memory may not operate
correctly if:
.The area of the windshield, where the
front camera is located, is not clean or is
affected by foreign objects, e.g. stickers,
window tinting, etc.
.Traffic signs are completely or partially
covered, are too low or high or difficult to
discern.
.Traffic signs are incorrectly mounted or
are damaged.
.Traffic signs do not comply with the
approved traffic sign standards.
.The speed limit is displayed by certain
types of electronic speed signs.
.There are adverse environmental
conditions, e.g. heavy rain, snow, direct
sunlight or shadows.
.The headlights are dirty or not correctly
aligned when driving at night.
.The navigation map data is out of date.
.The navigation map is unavailable.
Driver Attention Assist
If equipped, Driver Attention Assist alerts
the driver to pay closer attention to the
road ahead. Driver Attention Assist uses a
camera-based Driver Monitoring System. The
Driver Monitoring System on the steering
column continually monitors the driver's
head movements and eye gaze location to
determine if the driver is drowsy or
distracted. Depending on the level of the
driver’s distraction or drowsiness, Driver
Attention Assist will provide visual warnings,
chimes, and haptic movements to gently
guide the driver to look back at the road.
Sunglasses, hats, or other types of clothing
that change the shape of the head may
interfere with camera performance. To
improve camera performance, raise or lower
the steering wheel, or change the seat
position.
Driver Attention Assist does not record video
or audio. It is only active while driving with
the feature enabled.
How to Activate Driver Attention Assist
Driver Attention Assist turns on
automatically every time the vehicle is
started. The feature can be enabled or
disabled through vehicle settings. To view

Ais amber when
assisting. It may also provide a Lane
Departure Warning (LDW) alert by flashing
Aamber if the vehicle crosses a
detected lane marking. Additionally, there
may be three beeps, or the driver seat may
pulse three times, on the right or left,
depending on the lane departure direction. Take Steering
The LKA system does not continuously steer
the vehicle. If LKA does not detect active
driver steering, an alert and chime may be
provided. Steer the vehicle to dismiss. LKA
may become temporarily unavailable after
repeated take steering alerts.
When the System Does Not Seem to
Work Properly
The system performance may be
affected by:
.Close vehicles ahead.
.Sudden lighting changes, such as when
driving through tunnels.
.Banked roads.
.Roads with poor lane markings, such as
two-lane roads.
If the LKA system is not functioning
properly when lane markings are clearly
visible, cleaning the windshield may help.
A camera blocked message may display if
the camera is blocked. Some driver
assistance systems may have reduced
performance or not work at all. An LKA or
LDW unavailable message may display if the
systems are temporarily unavailable. This
message could be due to a blocked camera. The LKA system does not need service. Clean
the outside of the windshield behind the
rearview mirror.
LKA assistance and/or LDW alerts may occur
due to tar marks, shadows, cracks in the
road, temporary or construction lane
markings, or other road imperfections. This
is normal system operation; the vehicle does
not need service. Turn LKA off if these
conditions continue.
