208 DRIVING AND OPERATING
Warning (Continued)
on an entrance or exit ramp. Always
be ready to use the brakes if
necessary.
{Warning
On curves, ACC may respond to a
vehicle in another lane, or may not
have time to react to a vehicle in
your lane. You could crash into a
vehicle ahead of you, or lose control
of your vehicle. Give extra attention
in curves and be ready to use the
brakes if necessary. Select an
appropriate speed while driving in
curves.
ACC may operate differently in a
sharp curve. It may reduce the vehicle
speed if the curve is too sharp.
When following a vehicle and entering
a curve, ACC may not detect the
vehicle ahead and accelerate to the set
speed. When this happens, the vehicle
ahead indicator will not appear.
ACC may detect a vehicle that is not
in your lane and apply the brakes.
ACC may occasionally provide an alert
and/or braking that is considered
unnecessary. It could respond to vehicles in different lanes, signs,
guardrails, and other stationary
objects when entering or exiting a
curve. This is normal operation. The
vehicle does not need service.
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.

or on some vehicles, Off. The first
button press shows the current setting
on the DIC. Additional button presses
will change this setting. The chosen
setting will remain until it is changed
and will affect the timing of both the
Collision Alert and the Tailgating
Alert features. The timing of both
alerts will vary based on vehicle speed.
The faster the vehicle speed, the
farther away the alert will occur.
Consider traffic and weather
conditions when selecting the alert
timing. The range of selectable alert
timings may not be appropriate for all
drivers and driving conditions.
If your vehicle is equipped with
Adaptive Cruise Control (ACC),
changing the FCA timing setting
automatically changes the following
gap setting (Far, Medium, or Near).
Following Distance Indicator
The following distance to a moving
vehicle you are following is indicated
in following time in seconds on the
Driver Information Center (DIC). See
Driver Information Center (DIC)0139.
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 0217.
The system works when driving in a
forward gear between 8 km/h (5 mph)
and 60 km/h (37 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).

DRIVING AND OPERATING 223
LCA may not operate when the LCA
sensors in the left or right corners of
the rear bumper are covered with
mud, dirt, snow, ice, or slush, or in
heavy rainstorms. For cleaning
instructions, see "Washing the
Vehicle" underExterior Care0312.
If the DIC still displays the system
unavailable message after cleaning
both sides of the vehicle toward the
rear corners of the vehicle, see your
dealer.
If the LCA displays do not light up
when moving vehicles are in the side
blind zone or rapidly approaching this
zone and the system is clean, the
system may need service. Take the
vehicle to your dealer.
Radio Frequency Information
See Radio Frequency Statement 0349.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
crashes due to unintentional lane
departures. It may provide an alert if
the vehicle is crossing a lane without using a turn signal in that direction.
LDW uses a camera sensor to detect
the lane markings at speeds of 56
km/h (35 mph) or greater.
{Warning
The LDW system does not steer the
vehicle. The LDW system may not:
. Provide enough time to avoid
a 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.
If LDW only detects lane markings
on one side of the road, it will only
warn you when departing the lane (Continued)
Warning (Continued)
on the side where it has detected a
lane marking. 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 LDW in bad
weather conditions.
How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LDW on and off, press
@on
the center stack to the left of the
infotainment display. The control
indicator will light when LDW is on.

256 VEHICLE CARE
Washer Fluid
What to Use
When windshield washer fluid is
needed, be sure to read the
manufacturer's instructions before
use. If operating the vehicle in an area
where the temperature may fall below
freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
The appropriate message will appear
in the Driver Information Center (DIC)
when the fluid level is low.
Open the cap with the washer symbol
on it. Add washer fluid until the tank
is full. SeeEngine Compartment
Overview 0240 for reservoir location.
Caution
.
Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.
. Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
windshield washer system
and paint.
. Do not mix water with
ready-to-use washer fluid.
Water can cause the solution
to freeze and damage the
washer fluid tank and other
parts of the washer system.
. When using concentrated
washer fluid, follow the
manufacturer instructions for
adding water.
. Fill the washer fluid tank only
three-quarters full when it is
very cold. This allows for
fluid expansion if freezing
(Continued)
Caution (Continued)
occurs, which could damage
the tank if it is
completely full.
Brakes
Disc brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads 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. When the brake wear
warning sound is heard, have the
vehicle serviced.
