9-40 Driving and Operating
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
lights will come on. The automatic
braking may feel or sound different
than if the brakes were applied
manually. This is normal.
Stationary or Very Slow-Moving
Objects
{Warning
Adaptive Cruise Control (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 that it has never detected
moving. This can occur in
stop-and-go traffic or when a(Continued)
Warning (Continued)
vehicle suddenly appears due to
a vehicle ahead changing lanes.
Your vehicle may not stop and
could cause a crash. Use caution
when using ACC. Your complete
attention is always required while
driving and you should be ready
to take action and apply the
brakes.
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 electronic stability
control system has activated or
been disabled.
.No traffic or other objects are
being detected.
.There is a fault in the system. The ACC active symbol will not be
displayed when ACC is no longer
active.
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 symbol
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.
See
”Alert Type” and“Go Notifier” in
“Collision/Detection Systems” under
Vehicle Personalization on
page 5-48.
When the vehicle ahead drives
away, press RES+ or the
accelerator pedal to resume cruise
control. If stopped for more than
two minutes or if the driver door is
opened and the driver safety belt is
unbuckled, the ACC automatically

applies the electric parking brake to
hold the vehicle. The electric
parking brake status light will turn
on. SeeElectric Parking Brake on
page 9-27. To resume ACC and
release the electric parking brake,
press the accelerator pedal.
A DIC warning message may
display indicating to shift to P (Park)
before exiting the vehicle. See
Vehicle Messages on page 5-36.
{Warning
If ACC has stopped the vehicle,
and if ACC is disengaged, turned
off, or canceled, the vehicle will
no longer be held at a stop. The
vehicle can move. When ACC is
holding the vehicle at a stop,
always be prepared to manually
apply the brakes.
{Warning
Leaving the vehicle without
placing it in P (Park) can be
dangerous. Do not leave the
vehicle while it is being held at a
stop by ACC. Always place the
vehicle in P (Park) and turn off
the ignition before leaving the
vehicle.
ACC Override
If using the accelerator pedal while
ACC is active, a DIC warning
message will indicate that automatic
braking will not occur. See Vehicle
Messages on page 5-36. ACC will
resume operation when the
accelerator pedal is not being
pressed.
{Warning
The ACC will not automatically
apply the brakes if your foot is
resting on the accelerator pedal.
You could crash into a vehicle
ahead of you.
Curves in the Road
{Warning
On curves, ACC may not detect a
vehicle ahead in your lane. You
could be startled if the vehicle
accelerates up to the set speed,
especially when following a
vehicle exiting or entering exit
ramps. You could lose control of
the vehicle or crash. Do not use
ACC while driving on an entrance
or exit ramp. Always be ready to
use the brakes if necessary.

9-42 Driving and Operating
{Warning
On curves, ACC may respond to
a vehicle in another lane, or may
not have time to react to a vehicle
in your lane. You could crash into
a vehicle ahead of you, or lose
control of your vehicle. Give extra
attention in curves and be ready
to use the brakes if necessary.
Select an appropriate speed while
driving in curves.
ACC may operate differently in a
sharp curve. It may reduce the
vehicle speed if the curve is too
sharp.
When following a vehicle and
entering a curve, ACC may not
detect the vehicle ahead and
accelerate to the set speed. When
this happens, the vehicle ahead
symbol will not appear.
ACC may detect a vehicle that is
not in your lane and apply the
brakes. ACC may occasionally provide an
alert and/or braking that is
considered unnecessary. It could
respond to vehicles in different
lanes, signs, guardrails, and other
stationary objects when entering or
exiting a curve. This is normal
operation. The vehicle does not
need service.
Other Vehicle Lane Changes
ACC will not detect a vehicle ahead
until it is completely in the lane. The
brakes may need to be manually
applied.

Do Not Use ACC on Hills and
When Towing a Trailer
Do not use ACC when driving on
steep hills or when towing a trailer.
ACC will not detect a vehicle in the
lane while driving on steep hills. The
driver will often need to take over
acceleration and braking on steep
hills, especially when towing a
trailer. If the brakes are applied, the
ACC disengages.
Disengaging ACC
There are three ways to
disengage ACC:
.Step lightly on the brake pedal.
.Press*.
.Press].
Erasing Speed Memory
The cruise control set speed is
erased from memory if
]is
pressed or if the ignition is
turned off.
Cleaning the Sensing System
The camera sensor on the back of
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.
For cleaning instructions, see
“Washing the Vehicle” under
Exterior Care on page 10-82.
System operation may also be
limited under snow, heavy rain,
or road spray conditions.
Driver Assistance
Systems
This vehicle may have features that
work together to help avoid crashes
or reduce crash damage while
driving, backing, and parking. Read
this entire section before using
these systems.
{Warning
Do not rely on the Driver
Assistance Systems. These
systems do not replace the need
for paying attention and driving
safely. You may not hear or feel
alerts or warnings provided by
these systems. Failure to use
proper care when driving may
result in injury, death, or vehicle
damage. See Defensive Driving
on page 9-3.

Warning (Continued)
Under many conditions, these
systems will not:
.Detect children, pedestrians,
bicyclists, or animals.
.Detect vehicles or objects
outside the area monitored by
the system.
.Work at all driving speeds.
.Warn you or provide you with
enough time to avoid a crash.
.Work under poor visibility or
bad weather conditions.
.Work if the detection sensor
is not cleaned or is covered
by ice, snow, mud, or dirt.
Complete attention is always
required while driving, and you
should be ready to take action
and apply the brakes and/or steer
the vehicle to avoid crashes. Audible or Safety Alert Seat
Some driver assistance features
alert the driver of obstacles by
beeping. To change the volume of
the warning chime, see
“Comfort
and Convenience” underVehicle
Personalization on page 5-48.
If equipped with the Safety Alert
Seat, the driver seat cushion may
provide a vibrating pulse alert
instead of beeping. To change this,
see “Collision/Detection Systems”
under Vehicle Personalization on
page 5-48.
Assistance Systems for
Parking or Backing
When the vehicle is in R (Reverse),
the Rear Vision Camera (RVC) and
Rear Parking Assist may help the
driver to avoid a crash or to reduce
crash damage. Some models may
also have the Rear Automatic
Braking and Backing Warning
System, Rear Cross Traffic Alert
(RCTA), Automatic Parking Assist
(APA), and/or Front Parking Assist. When the vehicle is shifted into
R (Reverse), the RVC displays an
image of the area behind the vehicle
in the center stack display. The
previous screen displays when the
vehicle is shifted out of R (Reverse)
after a short delay. To return to the
previous screen sooner, press a
button on the infotainment system,
shift into P (Park), or reach a vehicle
speed of 8 km/h (5 mph).
{Warning
The RVC system does not display
children, pedestrians, bicyclists,
animals, or any other object
located outside the camera's field
of view, below the bumper,
or under the vehicle. Perceived
distances may be different from
actual distances. Do not back the
vehicle using only the RVC
screen, during longer, higher
speed backing maneuvers,
or where there could be cross

9-46 Driving and Operating
{Warning
The parking 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
parking assist, always check the
area around the vehicle and
check all mirrors before moving
forward or backing.
The instrument cluster may have a
parking assist display with bars that
show“distance to object” and object
location information for URPA, and
on some vehicles, for the Front
Parking Assist system. As the object
gets closer, more bars light up.
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 Front Parking Assist are
higher pitched than for Rear Parking
Assist. Vehicles with Adaptive Cruise
Control (ACC) have the Backing
Warning System, which is designed
to help avoid backing crashes. The
system can warn of rear objects
when backing up at speeds greater
than 8 km/h (5 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.

Driving and Operating 9-47
{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 system to occur. To prevent
injury, death, or vehicle damage,
even with the Backing Warning
System, always check the area
around the vehicle and check all
mirrors before backing.
Vehicles with Adaptive Cruise
Control (ACC) also have the Rear
Automatic Braking system, which is
designed to help avoid or reduce
the harm caused by backing
crashes. If the system detects the vehicle is backing too fast to avoid a
crash with a detected object, it may
automatically brake hard to a stop.
{Warning
Rear Automatic Braking may not
avoid many types of backing
crashes. Do not wait for the
automatic braking to apply. This
system is not designed to replace
driver braking, but only acts when
the vehicle may not stop in time.
The system, in some situations or
environments, may not brake or
may not brake in time to avoid a
crash. It does not detect children,
pedestrians, bicyclists, animals,
or objects below the bumper or
that are too close or too far from
the vehicle. To prevent injury,
death, or vehicle damage, even
with Rear Automatic Braking,
always check the area around the
vehicle before and while backing.
Pressing the brake pedal after the
vehicle comes to a stop will release
the Rear Automatic Braking. If the
brake pedal is not pressed within
two seconds after the stop, the
electric parking brake is set. When it
is safe, pressing the accelerator
pedal firmly at any time will override
the Rear Automatic Braking.
{Warning
There may be instances where
unexpected or undesired
automatic braking occurs. If this
happens, either press the brake
pedal or firmly press the
accelerator pedal to release the
brakes from the Rear Automatic
Braking system. Before releasing
the brakes, check the RVC
screen and check the area
around the vehicle to make sure it
is safe to proceed.

steers the vehicle into parallel
parking spots. When using APA,
you must still shift gears, and
control the brakes and accelerator.
The Driver information Center (DIC)
and audible beeps help to guide
parking maneuvers.
{Warning
APA does not apply the brakes.
APA may not detect objects in the
parking space, objects that are
soft or narrow, objects high off the
ground such as flatbed trucks,
or objects below ground level
such as large potholes. Always
verify that the parking space is
appropriate for parking a vehicle.
APA does not respond to changes
in the parking space, such as
movement of an adjacent vehicle,
or a person or object entering the
parking space. APA does not
detect or avoid traffic that is
behind or alongside of the
vehicle. Always be prepared to
stop the vehicle during the
parking maneuver.
