Seats and Restraints 63
Infants and Young Children
Everyone in a vehicle needs protection! This
includes infants and all other children.
Neither the distance traveled nor the age
and size of the traveler changes the need,
for everyone, to use safety restraints. In
fact, the law in every state in the United
States and in every Canadian province says
children up to some age must be restrained
while in a vehicle.
{Warning
Children can be seriously injured or killed
if the shoulder belt is worn behind their
back, under their legs, or wrapped around
their neck. The shoulder belt can tighten
but cannot be loosened if it is locked. The
shoulder belt locks when it is pulled all
the way out of the retractor. It unlocks
when the shoulder belt is allowed to go
all the way back into the retractor, but it
cannot do this if it is wrapped around the
child. Never leave children unattended in
a vehicle and never allow children to
improperly wear, or play with, the seat
belts.
Every time infants and young children ride
in vehicles, they should have the protection
provided by appropriate child restraints.
Neither the vehicle's seat belt system nor its
airbag system is designed for them.
Children who are not restrained properly can
strike other people, or can be thrown out of
the vehicle.
{Warning
Never hold an infant or a child while
riding in a vehicle. Due to crash forces, an
infant or a child will become so heavy it
is not possible to hold it during a crash.
For example, in a crash at only
40 km/h (25 mph), a 5.5 kg (12 lb) infant
will suddenly become a 110 kg (240 lb)
force on a person's arms. An infant or
child should be secured in an appropriate
child restraint.

72 Seats and Restraints
{Warning
To reduce the risk of serious or fatal
injuries during a crash, do not attach
more than one child restraint to a single
anchor. Attaching more than one child
restraint to a single anchor could cause
the anchor or attachment to come loose
or even break during a crash. A child or
others could be injured.
{Warning
Children can be seriously injured or
strangled if a shoulder belt is wrapped
around their neck. The shoulder belt can
tighten but cannot be loosened if it is
locked. The shoulder belt locks when it is
pulled all the way out of the retractor.
It unlocks when the shoulder belt is
allowed to go all the way back into the
retractor, but it cannot do this if it is
wrapped around a child’s neck. If the
shoulder belt is locked and tightened
around a child’s neck, the only way to
loosen the belt is to cut it.(Continued)
Warning (Continued)
Buckle any unused seat belts behind the
child restraint so children cannot reach
them. Pull the shoulder belt all the way
out of the retractor to set the lock, and
tighten the belt behind the child restraint
after the child restraint has been
installed.
Caution
Do not let the LATCH attachments rub
against the vehicle’s seat belts. This may
damage these parts. If necessary, move
buckled seat belts to avoid rubbing the
LATCH attachments.
Do not fold the rear seatback when the
seat is occupied. Do not fold the empty
rear seat with a seat belt buckled. This
could damage the seat belt or the seat.
Unbuckle and return the seat belt to its
stowed position, before folding the seat.
If you need to secure more than one child
restraint in the rear seat, see Where to Put
the Restraint 066. 1. Attach and tighten the lower
attachments to the lower anchors. If the
child restraint does not have lower
attachments or the desired seating
position does not have lower anchors,
secure the child restraint with the top
tether and the seat belt. Refer to the
child restraint manufacturer instructions
and the instructions in this manual.
1.1. Find the lower anchors for the desired seating position.
1.2. Put the child restraint on the seat.
1.3. Attach and tighten the lower attachments on the child restraint
to the lower anchors.
2. If the child restraint manufacturer recommends that the top tether be
attached, adjust the top tether to its full
length and attach it to the anchor. Refer
to the child restraint instructions and the
following steps:
2.1. Find the top tether anchor.
2.2. Route, attach and tighten the top tether according to your child
restraint instructions and the
following instructions:

instructions regarding the use of the top
tether. See Lower Anchors and Tethers
for Children (LATCH System) 067.
7. Before placing a child in the child restraint, make sure it is securely held in
place. To check, grasp the child restraint
at the seat belt path and attempt to
move it side to side and back and forth.
When the child restraint is properly
installed, there should be no more than
2.5 cm (1 in) of movement.
To remove the child restraint, unbuckle the
vehicle seat belt and let it return to the
stowed position. If the top tether is attached
to a top tether anchor, disconnect it.
If the head restraint was removed, reinstall
it before the seating position is used. See

Driving and Operating 211
Adaptive Cruise Control
(Advanced)
If equipped, Adaptive Cruise Control (ACC)
allows the cruise control set speed and a
following gap to be selected. Read this
entire section before using the system. The
following gap is the following time (or
distance) 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 a camera
and radar sensor(s) to detect other vehicles.
SeeRadio Frequency Statement 0331.
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 0204. 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 0182.
{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 camera sensor is blocked by snow,
ice, or dirt. The system may not
detect a vehicle ahead. Keep the
windshield and headlamps clean.
.When visibility is poor due to rain,
snow, fog, dirt, insect residue, or dust;
when other foreign objects obscure
the camera’s view; 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
.With extremely heavy cargo loaded in
the cargo area or rear seat
.When towing a trailer

Driving and Operating 219
Do Not Use ACC When Towing a Trailer
ACC should not be used when towing a
trailer.
Disengaging ACC
There are three ways to disengage ACC:
.Step lightly on the brake pedal.
.Press*.
.PressJ.
Erasing Speed Memory
The ACC set speed is erased from memory if
Jis pressed or if the ignition is turned off.
Weather Conditions Affecting ACC
System operation may be limited under
snow, heavy rain, or road spray conditions.
Accessory Installations and Vehicle
Modifications
Do not install or place any object around
the front camera windshield area that would
obstruct the front camera view.
Do not install objects on top of the vehicle
that overhang and obstruct the front
camera, such as a canoe, kayak, or other
items that can be transported on a roof rack
system. See Roof Rack System 082. Do not modify the hood, headlamps, or fog
lamps, as this may limit the camera’s ability
to detect an object.
Cleaning the Sensing System
The camera sensor on the windshield ahead
of the rearview mirror and the radar sensors
on the front of the vehicle can become
blocked by snow, ice, dirt, mud, or debis.
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” in this
section. Always consider driving conditions
before using either cruise control system.
For cleaning instructions, see “Washing the
Vehicle” underExterior Care 0304.
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 0182.
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. (Continued)

16060855) - 2023 - CRC - 2/9/22
Driving and Operating 227
Certain vehicle conditions and driver
interferences may also cancel automatic
parking:
.The driver manually steers the vehicle.
.The maximum allowed speed is exceeded.
.There is a failure with the APA system.
.Electronic stability control or antilock
brakes are activated.
.The parking brake is applied or vehicle is
shifted into Park (P).
.Driver unbuckles seat belt and
opens door.
System Limitations
Automatic Parking Assist has certain
limitations. The system cannot:
.The system cannot continue to operate if
the maneuver speed exceeds
5 km/h (3 mph).
.Detect whether a parking space is legal or
restricted.
.Detect pavement markings or lines
.Park the vehicle closely lined up with the
vehicle next to it, particularly if the spot
is approached at an angle or if the
parking space is angled.
.Park exactly centered in a very large spot.
.Always detect short curbs.
.Operate while towing any trailer.
.Function the vehicle is raised or lowered
by air suspension (if equipped).
.Detect or automatically react to
approaching traffic when exiting a
parallel spot
When the System Does Not Seem to Work
Properly
If the vehicle does not reverse into the
expected parking space, the system could be
maneuvering the vehicle into a previously
detected space.
Reverse Automatic Braking (RAB)
Backing Warning and RAB
Vehicles with Adaptive Cruise Control (ACC)
have the Backing Warning System and 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 sound from the rear, or five pulses will occur 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 crash.

The AEB system does not need service.
Front Pedestrian Braking (FPB)
System
If equipped, the FPB system may help avoid
or reduce the harm caused by front-end
crashes with nearby pedestrians when
driving in a forward gear. FPB displays an
amber indicator,
~, when a nearby
pedestrian is detected ahead. When
approaching a detected pedestrian too
quickly, FPB provides a red flashing alert on
the windshield and rapidly beeps or pulses
the driver seat. FPB can provide a boost to
braking or automatically brake the vehicle.
This system includes Intelligent Brake Assist
(IBA), and the Automatic Emergency Braking
(AEB) system may also respond to
pedestrians. See Automatic Emergency
Braking (AEB) 0231.
The FPB system can detect and alert to
pedestrians in a forward gear at speeds
between 8 km/h (5 mph) and 80 km/h
(50 mph). During daytime driving, the
system detects pedestrians up to a distance
of approximately 40 m (131 ft). During
nighttime driving, system performance is
very limited.
{Warning
FPB does not provide an alert or
automatically brake the vehicle, unless it
detects a pedestrian. FPB may not detect
pedestrians, including children:
.When the pedestrian is not directly
ahead, fully visible, or standing
upright, or when part of a group.
.Due to poor visibility, including
nighttime conditions, fog, rain,
or snow.
.If the FPB sensor is blocked by dirt,
snow, or ice.
.If the headlamps or windshield are not
cleaned or in proper condition.
Be ready to take action and apply the
brakes. For more information, see
Defensive Driving 0182. Keep the
windshield, headlamps, and FPB sensor
clean and in good repair.
FPB can be set to Off, Alert, or Alert and
Brake through vehicle settings. To view
available settings from the infotainment
screen, touch Settings > Vehicle > Collision/
Detection Systems.
