Intelligent Brake Assist (IBA),
and the Automatic Emergency
Braking (AEB) system may also
respond to pedestrians. See
Automatic Emergency Braking
(AEB)0328.
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. If the vehicle is
equipped with the Night Vision
system, during night time
driving, the vehicle can detect
and alert pedestrians when
driving in a forward gear.
{Warning
FPB does not provide an
alert or automatically brake
the vehicle, unless it detects (Continued)
Warning (Continued)
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 0240. Keep the
windshield, headlamps, and

.If the sensor is blocked by
dirt, snow, rain, or ice.
Be ready to take action and
apply the brakes. For more
information, see Defensive
Driving 0240. Keep the
Night Vision sensor clean
and in good repair. Pedestrian detection may not
be available in high outside
temperatures. An amber icon,
*, displays. The system does
not need service.
In rain, snow, or fog the image
may not be clear and the
direction of the road ahead
may not be seen. In more
severe weather conditions,
the image may be unclear and
unusable. The system does
not need service.
Keep the system sensor clean
by activating the rear window
washer when it is dark enough
for the system to operate.
If the Night Vision image still
looks blurry, use a soft wet
cloth to gently clean the
sensor camera lens and dry
thoroughly. The sensor is
behind the lower front grille
below the driver side
headlamp.
The camera must also be
aligned to work correctly.

{Warning
The LKA system does not
continuously steer the
vehicle. It may not keep the
vehicle in the lane or give a
Lane Departure Warning
(LDW) alert, even if a lane
marking is detected.
The LKA and LDW systems
may not:
.Provide an alert or enough
steering assist to avoid a
lane departure or crash.
.Detect lane markings
under poor weather or
visibility conditions. This
can occur if the windshield
or headlamps are blocked
by dirt, snow, or ice; if they
are not in proper
condition; or if the sun
shines directly into the
camera.
.Detect road edges.
.Detect lanes on winding or
hilly roads.(Continued)
Warning (Continued)
If LKA only detects lane
markings on one side of the
road, it will only assist or
provide an LDW alert when
approaching the lane on the
side where it has detected a
lane marking. Even with LKA
and LDW, you must steer
the vehicle. Always keep
your attention on the road
and maintain proper vehicle
position within the lane,
or vehicle damage, injury,
or death could occur. Always
keep the windshield,
headlamps, and camera
sensors clean and in good
repair. Do not use LKA in
bad weather conditions or
on roads with unclear lane
markings, such as
construction zones.
{Warning
Using LKA on slippery roads
could cause loss of control
of the vehicle and a crash.
Turn the system off.
{Warning
LKA will not alert the driver
if a towed trailer crosses
into an adjacent lane of
travel. Serious injury or
property damage may occur
if the trailer moves into
another lane. Always
monitor the trailer position
while towing to make sure it
is within the same lane as
the tow vehicle.
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

Engine Overheating
The vehicle has several
indicators to warn of the
engine overheating.
There is an engine coolant
temperature gauge on the
instrument cluster. See Engine
Coolant Temperature Gauge
0131. The vehicle may also
display a message on the
Driver Information
Center (DIC).
If the decision is made not to
lift the hood when this
warning appears, get service
help right away. See Roadside
Assistance Program 0470.
If the decision is made to lift
the hood, make sure the
vehicle is parked on a level
surface. Then check to see if
the engine cooling fan is
running. If the engine is
overheating, the fan should be
running. If it is not, do not
continue to run the engine.
Have the vehicle serviced.
Caution
Do not run the engine if
there is a leak in the engine
cooling system. This can
cause a loss of all coolant
and can damage the system
and vehicle. Have any leaks
fixed right away.
If Steam Is Coming from
the Engine Compartment
{Warning
Steam and scalding liquids
from a hot cooling system
are under pressure. Turning
the pressure cap, even a
little, can cause them to
come out at high speed and
you could be burned. Never
turn the cap when the
cooling system, including the
pressure cap, is hot. Wait for
the cooling system and
pressure cap to cool.
If No Steam Is Coming
from the Engine
Compartment
If an engine overheat warning
is displayed but no steam can
be seen or heard, the problem
may not be too serious.
Sometimes the engine can get
a little too hot when the
vehicle:
.Climbs a long hill on a
hot day.
.Stops after high-speed
driving.
.Idles for long periods in
traffic.
If the overheat warning is
displayed with no sign of
steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and
to the highest fan speed.
Open the windows as
necessary.

Caution (Continued)
.Fill the washer fluid tank
only three-quarters full
when it is very cold. This
allows for fluid expansion
if freezing occurs, which
could damage the tank if it
is completely full.
Brakes
Disc brake linings have built-in
wear indicators that make a
high-pitched warning sound
when the brake linings are
worn and new linings are
needed. The sound can come
and go or can be heard all the
time when the vehicle is
moving, except when applying
the brake pedal firmly.
{Warning
The brake wear warning
sound means that soon the
brakes will not work well.
That could lead to a crash.(Continued)
Warning (Continued)
When the brake wear
warning sound is heard,
have the vehicle serviced.
Caution
Continuing to drive with
worn-out brake linings could
result in costly brake repairs.
Some driving conditions or
climates can cause a brake
squeal when the brakes are
first applied, clearing up
following several applications.
This does not mean something
is wrong with the brakes.
Properly torqued wheel nuts
are necessary to help prevent
brake pulsation. When tires
are rotated, inspect brake
linings for wear and evenly
tighten wheel nuts in the
proper sequence to torque
specifications. See Capacities
and Specifications 0463. Brake pads should be replaced
as complete axle sets.
Brake Pedal Travel
See your dealer if the brake
pedal does not return to
normal height, or if there is a
rapid increase in pedal travel.
This could be a sign that brake
service may be required.
Replacing Brake System
Parts
Always replace brake system
parts with new, approved
replacement parts. If this is
not done, the brakes may not
work properly. The braking
performance can change in
many ways if the wrong brake
parts are installed or if parts
are improperly installed.
