The speedometer reading can
be displayed in either English
or metric units. See
Instrument Cluster (Base
Level)0106 or
Instrument Cluster (Uplevel)
0 108. 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.

310 Driving and Operating
Near Gap Setting
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
0342.
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. 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. To view available
settings for this feature, touch
the Settings icon on the
infotainment home page.
Select
“Vehicle” to display the
list of available options and
select “Collision/Detection
Systems”.

312 Driving and Operating
Warning (Continued)
complete attention is always
required while driving and
you should be ready to take
action and apply the brakes.
Irregular Objects
Affecting ACC
ACC may have difficulty
detecting the following
objects:
.Vehicles with cargo
extending from the back end.
.Non-standard shaped
vehicles, such as vehicle
transport, vehicles with a
side car fitted, or horse
carriages.
.Objects that are close to the
front of your vehicle.
ACC Automatically
Disengages
ACC may automatically
disengage and you will need to
manually apply the brakes to
slow the vehicle when:
.The sensors are blocked.
.The Traction Control System
(TCS) or StabiliTrak/ESC
system has activated or
been disabled.
.There is a fault in the
system.
.The radar falsely reports
blockage when driving in a
desert or remote area with
no other vehicles or
roadside objects.
.A DIC message may display
to indicate that ACC is
temporarily unavailable.
The ACC indicator will turn
white when ACC is no longer
active.
In some cases, when ACC will
not activate, regular Cruise
Control may be used. See
“Switching Between ACC and
Regular Cruise Control”
previously in this section.
Always consider driving
conditions before using either
cruise control system. Notification to Resume ACC
ACC will maintain a follow gap
behind a detected vehicle and
slow your vehicle to a stop
behind that vehicle.
If the stopped vehicle ahead
has driven away and ACC has
not resumed, the vehicle
ahead indicator will flash as a
reminder to check traffic
ahead before proceeding. In
addition, the left and right
sides of the Safety Alert Seat
will pulse three times, or three
beeps will sound. Touch the
Settings icon on the
infotainment home page.
Select
“Vehicle” to display the
list of available options and
select ”Alert Type” and

316 Driving and Operating
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
“Washing the Vehicle” under
Exterior Care 0455.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. If equipped with
Automatic Lane Change, 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 0149.
{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 monitor
the road conditions. You
may need to respond to
traffic events by steering,
braking, or accelerating. See
Defensive Driving.
Super Cruise is:
.Not a self-driving system
.Not a crash avoidance or
warning system
.Not a substitute for
proper supervision of the
driving task.

requested by the driver or
initiated by the Super Cruise
System.
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
0149.
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 with automatic
lane change, 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.
.Super Cruise System may
initiate a lane change to left
or right when current lane is
ending ahead.
.To cancel a Super Cruise
lane change, return the turn
signal lever to the neutral
position or move the turn
signal lever.
