Automatic Speed Limiter
Automatic Speed Limiter uses an on-board
camera and navigation data to identify
speed limit road signs and propose a new
set speed based on that data.
In Auto mode, you can adjust the set speed
with an offset above or below the identified
speed limit using the steering wheel
controls. See "Turning Speed Limiter On and
Off" later in this section.
{Warning
In Auto mode, Speed Limiter may not
prompt for set speed changes when
encountering conditional speed limit
signs, for example time frames or when
construction workers are present. To
avoid a crash, personal injury, or death,
always pay attention to posted signs and
follow applicable traffic laws. Manual Speed Limiter
Speed Limiter can also be used in Manual
mode. In Manual mode, all changes to the
set speed are controlled by the driver.
Selecting the Speed Limiter Mode
To enable Speed Limiter, select a Speed
Limiter mode. From the infotainment home
screen touch Controls > Drive (Drive & Park)

time between your vehicle and a vehicle
detected directly ahead in your path,
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. SeeRadio Frequency
Statement 0348.
If a vehicle is detected in your path, ACC can
apply acceleration or limited, moderate
braking to maintain the selected following
gap. To disengage ACC, apply the brake.
If ACC is controlling your vehicle speed
when the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control (ESC)
system activates, the ACC may automatically
disengage. See Traction Control/Electronic
Stability Control 0189. When road
conditions allow ACC to be safely used, the
ACC can be turned back on.
Disabling the TCS or StabiliTrak/ESC system
will disengage and prevent engagement
of ACC. 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.
ACC automatically slows the vehicle down
while navigating the curve and may increase
speed out of the curve, but will not exceed
the set speed.
{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 0164.
{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 may not detect a
vehicle ahead. Keep the entire front of
the vehicle clean.
.Visibility is poor due to rain, snow,
fog, dirt, insect residue, or dust; when
other foreign objects obscure the
camera and/or radar; or when the
vehicle in front or oncoming traffic
causes additional environmental
obstructions, such as road spray. ACC
performance is limited under these
conditions.
.On slippery roads where fast changes
in tire traction can cause excessive
wheel slip.

Near Gap Setting
If equipped, and a trailer is electrically
connected, the gap setting display will be as
follows:
Far Gap Setting with Trailer
Medium Gap Setting with Trailer
Near Gap Setting with Trailer
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 0233.

Alerting the Driver
With Head-Up Display
Without Head-Up Display
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 a list of available
options, on the infotainment home screen,
select Settings > Vehicle > Collision/
Detection Systems. See
Defensive Driving 0164.
Approaching and Following a Vehicle
The 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 for vehicles ahead.
ACC automatically slows the vehicle down
and adjusts vehicle speed to follow the
vehicle in front at the selected follow gap.
The vehicle speed increases or decreases to
follow the vehicle in front of you, but will
not exceed the set speed. It may apply
limited braking, if necessary. When braking
is active, the brake lamps will come on. The
automatic braking may feel or sound
different than if the brakes were applied
manually. This is normal. Passing a Vehicle While Using ACC
If the set speed is high enough, and the left
turn signal is used to pass a vehicle ahead
in the selected following gap, ACC may
assist by gradually accelerating the vehicle
prior to the lane change.
{Warning
When using ACC to pass a vehicle or
perform a lane change, the following
distance to the vehicle being passed may
be reduced. ACC may not apply sufficient
acceleration or braking when passing a
vehicle or performing a lane change.
Always be ready to manually accelerate
or brake to complete the pass or lane
change.
Stationary or Very Slow-Moving Objects
{Warning
ACC may not detect and react to stopped
or slow-moving vehicles ahead of you. For
example, the system may not brake for a
vehicle it has never detected moving. This
can occur in stop-and-go traffic or when a
vehicle suddenly appears due to a vehicle (Continued)
