254 DRIVING AND OPERATING
Ending Cruise Control
There are four ways to end cruise
control:
.Step lightly on the brake pedal.
.Press*.
.Shift the transmission to
N (Neutral).
.PressJ.
Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if the
ignition is turned off.
Adaptive Cruise Control
(Advanced)
If equipped, Adaptive Cruise Control
(ACC) allows the cruise control set
speed and following gap to be
selected. Read this entire section
before using this system. The
following gap is the following 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. See
Radio Frequency Statement
0406.
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 ACC is controlling your vehicle
speed when the traction control
system (TCS) or StabiliTrak electronic
stability control system activates, ACC
may automatically disengage. See
Traction Control/Electronic Stability
Control 0248. When road conditions
allow ACC to be safely used, 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.
{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 0219.
{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)

DRIVING AND OPERATING 259
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,
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 ahead changing
lanes. Your vehicle may not stop
and could cause a crash. Use (Continued)
Warning (Continued)
caution when using ACC. Your
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
the driver will need to manually apply
the brakes to slow the vehicle when:
.The sensors are blocked.
.The Traction Control System (TCS)
or StabiliTrak/ESC has activated or
been disabled.
.There is a fault in the system.

DRIVING AND OPERATING 263
Cleaning the Sensing System
The camera sensor on the windshield
behind the rearview mirror can
become blocked by snow, ice, dirt,
mud, or debris. This area needs to be
cleaned for ACC to operate properly.
The vehicle headlamps may need to
be cleaned due to dirt, snow, or ice.
Objects that are not illuminated
correctly may be difficult to detect.
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.

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 Park
Assist system. As the object gets
closer, more bars light up and the bars
change color from yellow to amber to
red. An obstacle is also indicated by
audible beeps. The interval between
the beeps becomes shorter as the
vehicle gets closer to the obstacle.
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 (<0.6 m (2 ft) in the
vehicle rear, or <0.3 m (1 ft) in the
vehicle front), five beeps will sound
from the front or rear 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.
Backing Warning and Reverse
Automatic Braking (RAB)
Vehicles with Adaptive Cruise Control
(ACC) have the Backing Warning
System and Reverse Automatic
Braking (RAB) system. When in R (Reverse), Backing Warning alerts of
rear objects at vehicle speeds greater
than 8 km/h (5 mph), and RAB may
automatically brake hard at speeds
between 1–32 km/h (0.5–20 mph).
The Backing Warning System will
beep once from the rear when an
object is first detected, or pulse twice
on both sides of the Safety Alert Seat.
When the system detects a potential
crash, beeps will be heard from the
rear, or five pulses will be felt on both
sides of the Safety Alert Seat. There
may also be a brief, sharp application
of the brakes.
{Warning
The Backing Warning System only
operates at speeds greater than
8 km/h (5 mph). It does not detect
children, pedestrians, bicyclists,
animals, or objects below the
bumper or that are too close or too
far from the vehicle. In some
situations, such as at higher
backing speeds, there may not be
enough time for the short, sharp
application of the vehicle brake

windshield and rapidly beeps or pulses
the driver 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). If the vehicle has Adaptive
Cruise Control (ACC), it can detect
vehicles to distances of approximately
110 m (360 ft) and operates at all
speeds. SeeAdaptive Cruise Control
(Advanced) 0254.
{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
(Continued)
Warning (Continued)
objects. Be ready to take action and
apply the brakes. SeeDefensive
Driving 0219.
FCA can be disabled. See “Collision/
Detection Systems” underVehicle
Personalization 0130.
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.
{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.
