266 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 0121.
{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 blind spot areas. When the
vehicle is in a forward gear, the left or

270 DRIVING AND OPERATING
How the System Works
LKA uses a camera sensor installed on
the windshield ahead of the rearview
mirror to detect lane markings. It may
provide brief steering assist if it
detects an unintended lane departure.
It may further provide an audible alert
or the driver seat may pulse indicating
that a lane marking has been crossed.
The system does not provide a Lane
Departure Warning (LDW) when
intentionally steering across a lane
marker.
To turn LKA on and off, press
Aon
the center stack. If equipped, the
indicator light on the button comes
on when LKA is on and turns off
when LKA is disabled. In some
vehicles a long press of over
three seconds is required to turn
LKA off.
When on,
Ais white, if equipped,
indicating that the system is not ready
to assist.
Ais green if LKA is ready
to assist. LKA may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane
marking.
Ais amber when assisting. It may also provide a Lane
Departure Warning (LDW) alert by
flashing
Aamber if the vehicle
crosses a detected lane marking.
Additionally, there may be three
beeps, or the driver seat may pulse
three times, on the right or left,
depending on the lane departure
direction.
Take Steering
The LKA system does not
continuously steer the vehicle. If LKA
does not detect active driver steering,
an alert and chime may be provided.
Steer the vehicle to dismiss. LKA may
become temporarily unavailable after
repeated take steering alerts.
When the System Does Not
Seem to Work Properly
The system performance may be
affected by:
.Close vehicles 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. 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.

DRIVING AND OPERATING 275
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 are
important 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 SeeManual Mode
0 231.
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:
.Automatic Emergency
Braking (AEB)
.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
when a trailer is towed. Use caution
while changing lanes when towing a
trailer.
If equipped with Rear Cross Traffic
Alert (RCTA), 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.
