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.
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
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 if:
.
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 a
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when ACC is no longer active.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 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 “Adaptive Cruise Go
Notifier” in“Collision/Detection
Systems” underVehicle Personalization
0 145.
When the vehicle ahead drives away,
press +RES or the accelerator pedal to
resume ACC. If stopped for more than
two minutes or if the driver door is
opened and the driver seat belt is
unbuckled, the ACC automatically
applies the Electric Parking Brake
(EPB) to hold the vehicle. The EPB
status light will turn on. See Electric
Parking Brake 0205. To release the
EPB, press the accelerator pedal.

226 DRIVING AND OPERATING
Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if
the ignition is turned off.
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 0335.
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 0179.
Under many conditions, these
systems will not: . Detect children, pedestrians,
bicyclists, or animals.
(Continued)
Warning (Continued)
.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.
. Work if the detection sensor
is covered up, such as with a
sticker, magnet, or metal
plate.
. Work if the area surrounding
the detection sensor is
damaged or not properly
repaired.
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.

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
where the object is detected, 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
Vehicles with Adaptive Cruise Control
(ACC) have the Backing Warning and
Reverse Automatic Braking (RAB)
system. The Backing Warning part of
this 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.
When the vehicle is in R (Reverse),
if the system detects the vehicle is
backing too fast to avoid a crash with
a detected object behind your vehicle
in your path, it may automatically
brake hard to a stop to help avoid or
reduce the harm caused by a backing
crash.
{Warning
RAB 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 and only works in
R (Reverse) when an object is
detected directly behind the vehicle.
It may not brake or stop in time to
avoid a crash. It will not brake for
objects when the vehicle is moving
at very low speeds. 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 RAB, 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 Reverse Automatic Braking. If the
brake pedal is not pressed soon after
the stop, the electric parking brake
may be set. When it is safe, press the

accelerator pedal firmly at any time to
override the Reverse 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 RAB
system. Before releasing the brakes,
check the RVC and check the area
around the vehicle to make sure it
is safe to proceed.
Rear Cross Traffic Alert (RCTA)
If equipped, RCTA displays a red
warning triangle with a left or right
pointing arrow on the infotainment
display to warn of traffic coming from
the left or right. This system detects
objects coming from up to 20 m (65 ft)
from the left or right side of the
vehicle. When an object is detected,
either three beeps sound from the left
or right or three Safety Alert Seat pulses occur on the left or right side,
depending on the direction of the
detected vehicle.
Use caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out from
the back of the vehicle do not move
further back when a trailer is towed.
Turning the Features On or Off
TheXbutton on the center stack is
used to turn on or off the Front and
Rear Park Assist, Rear Cross Traffic
Alert, Backing Warning, and Reverse
Automatic Braking system at the same
time. The indicator light next to the
button comes on when the features
are on and turns off when the features
have been disabled.
Turn off Park Assist and Reverse
Automatic Braking when towing a
trailer. RCTA can also be turned on or off
through vehicle personalization. See
“Collision/Detection Systems”
under
Vehicle Personalization 0145.
Automatic Parking Assist (APA)
If equipped, APA searches for and
steers the vehicle into parallel and
perpendicular parking spots. When
using APA, you must still shift gears,
and control the brakes and
accelerator. A display 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

the status of the parking maneuver.
Depending on the space size,
additional maneuvers may be
required, and there will be additional
instructions. When changing gears,
allow the automatic steering to
complete before continuing the
parking maneuver. Upon successful
completion of a maneuver, APA will
beep and display a PARKING
COMPLETE message. Place the vehicle
in P (Park).
APA may automatically disengage if:
.The steering wheel is used by the
driver.
. The maximum allowed speed is
exceeded.
. There is a failure with the APA
system.
. Electronic stability control or
antilock brakes are activated.
. A high priority vehicle message is
displayed in the DIC.
To cancel APA, press
Oagain. When the System Does Not Seem to
Work Properly
The APA system may require a short
period of driving along curves to
calibrate.
Assistance Systems for
Driving
If equipped, when driving the vehicle
in a forward gear, Forward Collision
Alert (FCA), Lane Departure Warning
(LDW), Lane Keep Assist (LKA), Side
Blind Zone Alert (SBZA), Lane Change
Alert (LCA), and/or Forward
Automatic Braking (FAB) can help to
avoid a crash or reduce crash damage.
Forward Collision Alert
(FCA) System
If equipped, the FCA system may help
to avoid or reduce the harm caused by
front-end crashes. When approaching
a vehicle ahead too quickly, FCA
provides a flashing red alert on the
windshield and rapidly beeps or pulses
the Safety Alert 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 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. See
Adaptive Cruise Control
0 218.
{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
objects. Be ready to take action and
apply the brakes. See Defensive
Driving 0179.

DRIVING AND OPERATING 237
.Clean the entire front of the
vehicle.
. Clean the headlamps.
Forward Automatic
Braking (FAB)
If the vehicle has Adaptive Cruise
Control (ACC), it also has FAB, which
includes Intelligent Brake Assist (IBA).
When the system detects a vehicle
ahead in your path that is traveling in
the same direction that you may be
about to crash into, it can provide a
boost to braking or automatically
brake the vehicle. This can help avoid
or lessen the severity of crashes when
driving in a forward gear. Depending
on the situation, the vehicle may
automatically brake moderately or
hard. This forward automatic braking
can only occur if a vehicle is detected.
This is shown by the FCA vehicle
ahead indicator being lit. See Forward
Collision Alert (FCA) System 0234.
The system works when driving in a
forward gear above 4 km/h (2 mph).
It can detect vehicles up to
approximately 60 m (197 ft).
{Warning
FAB is an emergency crash
preparation feature and is not
designed to avoid crashes. Do not
rely on FAB to brake the vehicle.
FAB will not brake outside of its
operating speed range and only
responds to detected vehicles.
FAB may not: . Detect a vehicle ahead on
winding or hilly roads.
. Detect all vehicles, especially
vehicles with a trailer,
tractors, muddy vehicles, etc.
. Detect a vehicle when
weather limits visibility, such
as in fog, rain, or snow.
. Detect a vehicle ahead if it is
partially blocked by
pedestrians or other objects.
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. FAB may slow the vehicle to a
complete stop to try to avoid a
potential crash. If this happens, FAB
may engage the Electric Parking Brake
(EPB) to hold the vehicle at a stop. To
release automatic braking, release the
EPB or firmly press the accelerator
pedal.
{Warning
FAB may automatically brake the
vehicle suddenly in situations
where it is unexpected and
undesired. It could respond to a
turning vehicle ahead, guardrails,
signs, and other non-moving
objects. To override FAB, firmly
press the accelerator pedal, if it is
safe to do so.
Intelligent Brake Assist (IBA)
IBA may activate when the brake
pedal is applied quickly by providing a
boost to braking based on the speed
of approach and distance to a vehicle
ahead.

.Sudden lighting changes, such as
when driving through tunnels.
. Banked roads.
. Roads with poor lane markings,
such as two-lane roads.
If the LKA system is not functioning
properly when lane markings are
clearly visible, cleaning the windshield
may help.
A camera blocked message may
display if the camera is blocked.
Cleaning the outside of the windshield
behind the rearview mirror may
correct the issue. Some driver
assistance systems may have reduced
performance or not work at all. An
LKA or LDW unavailable message may
display if the systems are temporarily
unavailable. This message could be
due to a blocked camera. The LKA
system does not need service. Clean
the outside of the windshield behind
the rearview mirror.
LKA assistance and/or LDW alerts
may occur due to tar marks, shadows,
cracks in the road, temporary or
construction lane markings, or other
road imperfections. This is normal system operation; the vehicle does not
need service. Turn LKA off if these
conditions continue.
Vehicle-to-Vehicle
If equipped and traveling in the U.S.
or Canada, Vehicle-to-Vehicle (V2V)
can communicate with other
V2V-equipped vehicles to send and
receive vehicle location, speed,
direction, and notices regarding
certain traffic situations from up to
approximately 300 m (980 ft) away.
Under certain conditions, V2V may
provide notice of certain traffic
situations, such as when other
V2V-equipped vehicles ahead may be
braking hard, disabled, on slippery
roads, or in a crash.
V2V does not automatically brake or
steer the vehicle.
{Warning
V2V features work only when other
nearby vehicles equipped with V2V
are detected and communications
(Continued)
Warning (Continued)
are received. V2V may not detect
other V2V-equipped vehicles or
receive communications under
certain conditions, including
around tall buildings; in parking
garages; around airports; in tunnels
and underpasses; in an area with
very dense trees; or where the roof
antenna is blocked by objects such
as roof carriers, snow or ice.
Communication failures or delays
can occur and may not provide
notice sufficiently in advance to
help avoid a crash, or may not
provide any notices at all. Pay
attention to the road and operation
of the vehicle at all times and be
ready to take action and apply the
brakes. SeeDefensive Driving 0179.

inadequate for the load, the vehicle
may not stop as expected. You and
others could be seriously injured.
The vehicle may also be damaged,
and the repairs would not be
covered by the vehicle warranty.
Pull a trailer only if all the steps in
this section have been followed. Ask
your dealer for advice and
information about towing a trailer
with the vehicle.
Driving with a Trailer
Trailering is different than just driving
the vehicle by itself. Trailering means
changes in handling, acceleration,
braking, durability, and fuel economy.
Successful, safe trailering takes correct
equipment, and it has to be used
properly.
The following information has many
time-tested, important trailering tips
and safety rules. Many of these areimportant for your safety and that of
your passengers. Read this section
carefully before pulling a trailer.
When towing a trailer:
.
Become familiar with and follow
all state and local laws that apply
to trailer towing. These
requirements vary from state to
state.
. State laws may require the use of
extended side view mirrors. Even if
not required, you should install
extended side view mirrors if your
visibility is limited or restricted
while towing.
. Do not tow a trailer during the
first 800 km (500 mi) of vehicle
use to prevent damage to the
engine, axle, or other parts.
. It is recommended to perform the
first oil change before heavy
towing.
. During the first 800 km (500 mi) of
trailer towing, do not drive over
80 km/h (50 mph) and do not
make starts at full throttle. .
Vehicles can tow in D (Drive).
If the transmission downshifts too
often, a lower gear may be
selected using Manual Mode See
Manual Mode 0203.
If equipped, the following driver
assistance features should be turned
off when towing a trailer:
. Adaptive Cruise Control (ACC)
. Super Cruise Control
. Lane Keep Assist (LKA)
. Park Assist
. Automatic Parking Assist (APA)
. Reverse Automatic Braking (RAB)
If equipped, the following driver
assistance features should be turned
to alert or off when towing a trailer:
. Forward Automatic Braking
System (FAB)
. Intelligent Brake Assist (IBA)
. Front Pedestrian Braking (FPB)
If equipped with Lane Change Alert
(LCA), the LCA detection zones that
extend back from the side of the
vehicle do not move further back
