218 DRIVING AND OPERATING
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
J.
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.
For cleaning instructions, see
“Washing the Vehicle
”under Exterior
Care 0324.
System operation may also be limited
under snow, heavy rain, or road spray
conditions.

DRIVING AND OPERATING 223
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 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
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.

12146119) - 2019 - crc - 7/27/18
224 DRIVING AND OPERATING
{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
RAB. If the brake pedal is not pressed
soon after the stop, the Electric Parking Brake (EPB) may be set. When
it is safe, press the accelerator pedal
firmly at any time to override RAB.
{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.
See
Radio Frequency Statement 0359.
Turning the Features On or Off
TouchXon the center stack to turn
on or off the Front and Rear Park
Assist, Reverse Automatic Braking
(RAB), Rear Cross Traffic Alert
(RCTA), and the Backing Warning
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, RCTA, and RAB
when towing a trailer.
To turn the RPA symbols or guidance
lines (on some models) on or off, see
“Rear Camera ”under Vehicle
Personalization 0147.

Driver Information Center (DIC). See
Driver Information Center (DIC)0140.
The minimum following time is
0.5 seconds away. If there is no vehicle
detected ahead, or the vehicle ahead is
out of sensor range, dashes will be
displayed.
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, this may correct the
issue:
. Clean the outside of the
windshield in front of the rearview
mirror.
. Clean the entire front of the
vehicle.
. Clean the headlamps.
Forward Automatic
Braking (FAB)
If the vehicle has Forward Collision
Alert (FCA), 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 0226.
The system works when driving in a
forward gear between 8 km/h (5 mph)
and 80 km/h (50 mph), or on vehicles
with Adaptive Cruise Control (ACC),
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.

232 DRIVING AND OPERATING
Without Head-Up Display
When the vehicle approaches a
pedestrian ahead too rapidly, the red
FPB alert display will flash on the
windshield. Eight rapid high-pitched
beeps will sound from the front,
or both sides of the Safety Alert Seat
will pulse five times. When this
Pedestrian Alert occurs, the brake
system may prepare for driver braking
to occur more rapidly which can cause
a brief, mild deceleration. Continue to
apply the brake pedal as needed.
Cruise control may be disengaged
when the Front Pedestrian Alert
occurs.
Automatic Braking
If FPB detects it is about to crash into
a pedestrian directly ahead, and the
brakes have not been applied, FPB
may automatically brake moderately
or brake hard. This can help to avoid some very low speed pedestrian
crashes or reduce pedestrian injury.
FPB can automatically brake to
detected pedestrians between 8 km/h
(5 mph) and 80 km/h (50 mph).
Automatic braking levels may be
reduced under certain conditions,
such as higher speeds.
If this happens, Automatic Braking
may engage the Electric Parking Brake
(EPB) to hold the vehicle at a stop.
Release the EPB. A firm press of the
accelerator pedal will also release
Automatic Braking and the EPB.
{Warning
FPB may alert or automatically
brake the vehicle suddenly in
situations where it is unexpected
and undesired. It could falsely alert
or brake for objects similar in shape
or size to pedestrians, including
shadows. This is normal operation
and the vehicle does not need
service. To override Automatic
Braking, firmly press the accelerator
pedal, if it is safe to do so.
Automatic Braking can be disabled
through vehicle personalization. See
“Front Pedestrian Detection
”in
“Collision/Detection Systems” under
Vehicle Personalization 0147.
{Warning
Using the Front Pedestrian Braking
system while towing a trailer could
cause you to lose control of the
vehicle and crash. Turn the system
to Alert or Off when towing a
trailer.
Cleaning the System
If FPB does not seem to operate
properly, cleaning the outside of the
windshield in front of the rearview
mirror may correct the issue.
Side Blind Zone
Alert (SBZA)
If equipped, the SBZA system is a
lane-changing aid that assists drivers
with avoiding crashes that occur with
moving vehicles in the side blind zone
(or spot) areas. When the vehicle is in

12146119) - 2019 - crc - 7/27/18
DRIVING AND OPERATING 249
Tires
.Do not tow a trailer while using a
compact spare tire on the vehicle.
. Tires must be properly inflated to
support loads while towing a
trailer. See Tires0284 for
instructions on proper tire
inflation.
Safety Chains
Always attach chains between the
vehicle and the trailer, and attach the
chains to the holes on the trailer hitch
platform. Instructions about safety
chains may be provided by the hitch
manufacturer or by the trailer
manufacturer.
Cross the safety chains under the
tongue of the trailer to help prevent
the tongue from contacting the road if
it becomes separated from the hitch.
Always leave just enough slack so the
combination can turn. Never allow
safety chains to drag on the ground.
Trailer Brakes
Loaded trailers over 450 kg (1,000 lb)
must be equipped with brake systems
and with brakes for each axle. Trailer
braking equipment conforming to
Canadian Standards Association (CSA)
requirement CAN3-D313, or its
equivalent, is recommended.
State or local regulations may require
trailers to have their own braking
system if the loaded weight of the
trailer exceeds certain requirements
that can vary from state to state.
Read and follow the instructions for
the trailer brakes so they are installed,
adjusted, and maintained properly.
Never attempt to tap into your
vehicle's hydraulic brake system.
If you do, both the vehicle anti-lock
brakes and the trailer brakes may not
function and could result in a crash.
Trailer Wiring
The trailer wiring harness (if
equipped), with a 7-pin connector is
located at the rear of the vehicle, and
it is tied to the vehicle's frame.
If the vehicle is not equipped with a
7-pin trailer connector, the body
harness has provisions to connect a
trailer harness and a 7-pin trailer
connector which is available through
your dealer.
Use only a round, seven-wire
connector with flat blade terminals
meeting SAE J2863 specifications for
proper electrical connectivity.

304 VEHICLE CARE
Tire Chains
{Warning
If the vehicle has a tire size other
than 235/65R18, do not use tire
chains. There is not enough
clearance. Tire chains used on a
vehicle without the proper amount
of clearance can cause damage to
the brakes, suspension, or other
vehicle parts. The area damaged by
the tire chains could cause loss of
control and a crash. Use another
type of traction device only if its
manufacturer recommends it for
the vehicle's tire size combination
and road conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive slow
and readjust or remove the traction
device if it contacts the vehicle. Do
not spin the wheels. If traction
devices are used, install them on
the front tires.
Caution
If the vehicle is equipped with 235/
65R18 size tires, use tire chains
only where legal and only when
necessary. Use low profile chains
that add no more than 12 mm
thickness to the tire tread and inner
sidewall. Use chains that are the
proper size for the tires. Install
them on the tires of the front axle.
Do not use chains on the tires of
the rear axle. Tighten them as
tightly as possible with the ends
securely fastened. Drive slowly and
follow the chain manufacturer's
instructions. If the chains contact
the vehicle, stop and retighten
them. If the contact continues, slow
down until it stops. Driving too fast
or spinning the wheels with chains
on will damage the vehicle.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires are
maintained properly. SeeTires0284. If air goes out of a tire, it is much
more likely to leak out slowly. But if
there is ever a blowout, here are a few
tips about what to expect and what
to do:
If a front tire fails, the flat tire creates
a drag that pulls the vehicle toward
that side. Take your foot off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, and then gently brake to a
stop, well off the road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and may
require the same correction as used in
a skid. Stop pressing the accelerator
pedal and steer to straighten the
vehicle. It may be very bumpy and
noisy. Gently brake to a stop, well off
the road, if possible.
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
