WARNING (CONTINUED)
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.
.There is no traffic or other
objects to detect.
.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displayed when ACC is no longer
active.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 vehicle ahead has driven
away and ACC has not resumed,
the vehicle ahead symbol will flash
as a reminder. 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” underVehicle
Personalization on page 5‑44.
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. See Electric Parking Brake on
page 9‑26. To resume ACC and release the electric parking brake,
press the accelerator pedal and
then RES+.
{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.

9-40 Driving and Operating
ACC Override
If using the accelerator pedal while
ACC is active, a DIC warning
message will indicate that automatic
braking will not occur. SeeVehicle
Messages on page 5‑34. 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 (Continued)
WARNING (CONTINUED)
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.
{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.

Driving and Operating 9-41
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.
Using ACC on Hills and When
Towing a Trailer
Do not use ACC when driving on
steep hills or when towing a trailer.
The performance of ACC when
driving on hills and when towing a
trailer depends on the vehicle
speed, vehicle load, traffic
conditions, and steepness of the
hills. It may not detect a vehicle in
the lane while driving on hills. When
going up steep hills, the accelerator
pedal may need to be pressed to
maintain the vehicle speed. When
going downhill, especially when
towing a trailer, the brakes may
need to be applied by the driver to
slow the vehicle down. If the brakes
are applied, ACC disengages.
Disengaging ACC
There are three ways to
disengage ACC:
.Step lightly on the brake pedal.
.Press*.
.Press].

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 10‑76.
System operation may also be
limited under 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 this
system.
{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.
(Continued)
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.

Driving and Operating 9-45
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.{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.

9-46 Driving and Operating
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. Check the RVC
screen and check the area
around the vehicle before
proceeding.

Driving and Operating 9-47
(SBZA), and/or the Active
Emergency Braking System can
help to avoid a crash or reduce
crash damage.
Forward Collision Alert
(FCA) System
The FCA system may help to avoid
or reduce the harm caused by
front-end crashes. FCA provides a
flashing alert on the windshield, and
beeps or pulses the Safety Alert
Seat when approaching a vehicle
directly ahead too quickly. FCA also
provides a 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 40 km/h (25 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 on
page 9‑34.
{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. FCA does not warn
of pedestrians, animals, signs,
guardrails, bridges, construction
barrels, or other objects. Be ready
to take action and apply the
brakes. For more information, see
Defensive Driving on page 9‑3.
FCA can be disabled through
vehicle personalization. See the
“Auto Collision Preparation” portion
of “Collision/Detection Systems”
under Vehicle Personalization on
page 5‑44.
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. The vehicle-ahead indicator
will display green when a vehicle is
detected in front. Vehicles may not
be detected on curves, highway exit
ramps, or hills; or due to poor
visibility. 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,

Selecting the Alert Timing
With Adaptive Cruise Control
Without Adaptive Cruise ControlPress the collision alert/following
distance button on the steering
wheel to set the FCA timing to Far,
Medium, Near, or on some vehicles,
Off. 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
timing may not be appropriate for all
drivers and driving conditions.
Changing the FCA timing setting
automatically changes the follow
distance setting (Far, Medium,
or Near) for the Adaptive Cruise
Control (ACC) feature.
Unnecessary Alerts
FCA may provide unnecessary
alerts for turning vehicles, vehicles
in other lanes, objects that are not
vehicles, or shadows. These alerts
are normal operation and the
vehicle does not need service.
Cleaning the System
If the FCA system does not seem to
operate properly, cleaning the
outside of the windshield in front of
the camera sensor and the front of
the vehicle may correct the issue.
Active Emergency
Braking System
If the vehicle has Adaptive Cruise
Control (ACC) it also has the Active
Emergency Braking System, which
includes Intelligent Brake
Assist (IBA) and the Automatic
Collision Preparation (ACP) System.
