SAFETY245
It is unsafe to test the FCW system. To prevent
such misuse of the system, after four Active
Braking events within a key cycle, the Active
Braking portion of FCW will be deactivated until
the next key cycle.
The FCW system is intended for on-road use
only. If the vehicle is taken off-road, the FCW
system should be deactivated to prevent unnec -
essary warnings to the surroundings.
Turning FCW On Or Off
The Forward Collision menu setting is located in
the Uconnect settings.
NOTE:The default status of FCW is “on”, this allows the
system to warn you of a possible collision with the
vehicle in front of you. Changing the FCW status to “off” deactivates the
system, so no warning or active braking will be
available in case of a possible collision.
NOTE:
The FCW system state is kept in memory from
one key cycle to the next. If the system is turned
off, it will remain off when the vehicle is
restarted.
FCW can work in conjunction with the KeySense
function of the vehicle (if equipped)
Ú
page 115.
FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking status are
programmable through the Uconnect system
Úpage 189.
The default sensitivity of FCW is the “Medium”
setting and the system status is “Warning &
Braking”. This allows the system to warn the driver
of a possible collision with the vehicle in front using
audible/visual warnings and it applies
autonomous braking.
By changing the FCW status setting to "Far", the
system provides possible collision warnings on
objects farther away. This results in earlier
warnings and provides the most reaction time to
avoid possible collisions By changing the FCW status setting to "Near", the
system provides possible collision warnings on
objects closer to the vehicle. This results in later
warnings and provides less reaction time than the
"Far" and "Medium" settings, which allows for a
more dynamic driving experience.
NOTE:
Changing the FCW status to “Only Warning”
prevents the system from providing limited
active braking, or additional brake support if the
driver is not braking adequately in the event of
a potential frontal collision, but maintains the
audible and visual warnings.
Changing the FCW status to “Off” prevents the
system from providing autonomous braking, or
additional brake support if the driver is not
braking adequately in the event of a potential
frontal collision.
The system will retain the last setting selected
by the driver after ignition shut down.
FCW may not react to irrelevant objects such as
overhead objects, ground reflections, objects
not in the path of the vehicle, stationary objects
that are far away, oncoming traffic, or leading
vehicles with the same or higher rates of speed.
FCW will be disabled like ACC, with the
unavailable screens.
WARNING!
Forward Collision Warning (FCW) is not intended
to avoid a collision on its own, nor can FCW
detect every type of potential collision. The driver
has the responsibility to avoid a collision by
controlling the vehicle via braking and steering.
Failure to follow this warning could lead to
serious injury or death.

FCW Limited Warning
If the instrument cluster displays “ACC/FCW
Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield”
momentarily, there may be a condition that limits
FCW functionality. Although the vehicle is still
drivable under normal conditions, the active
braking may not be fully available. Once the
condition that limited the system performance is
no longer present, the system will return to its full
performance state. If the problem persists, see an
authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster
displays:
ACC/FCW Unavailable Service Required
Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault.
Although the vehicle is still drivable under normal
conditions, have the system checked by an
authorized dealer.
Pedestrian Emergency Braking (PEB) — If
Equipped
The Pedestrian Emergency Braking (PEB) is a
subsystem of the FCW system which provides the
driver with audible and visual warnings in the
instrument cluster display, and may apply
automatic braking when it detects a potential
frontal collision with a pedestrian.
If a PEB event begins at a speed below 37 mph
(60 km/h), the system may provide braking to
mitigate the potential collision with a pedestrian. If
the PEB event stops the vehicle completely, the
system will hold the vehicle at a standstill for two
seconds and then release the brakes. When the
system determines a collision with the pedestrian
in front of you is no longer probable, the warning
message will be deactivated.
The minimum speed for PEB activation is 3 mph
(5 km/h). Turning PEB On Or Off
NOTE:The default status of PEB is “On.” This allows the
system to warn you of a possible frontal collision
with the pedestrian.
The PEB button is located in the Uconnect display
in the Controls settings Ú
page 189.
To turn the PEB system off, push the Pedestrian
Emergency Braking OFF button.
To turn the PEB system back on, push the Warning
Active Braking button.
Changing the PEB status to “Off” deactivates the
system, so no warning or active braking will be
available in case of a possible frontal collision with
the pedestrian.
NOTE:The PEB system will NOT retain the last setting
selected by the driver after ignition shut down. The
system will reset to the default setting when the
vehicle is restarted.
WARNING!
Pedestrian Emergency Braking (PEB) is not
intended to avoid a collision on its own, nor can
PEB detect every type of potential collision with
a pedestrian. The driver has the responsibility to
avoid a collision by controlling the vehicle via
braking and steering. Failure to follow this
warning could lead to serious injury or death.

Maintaining Your Air Bag System Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like
situations, such as an air bag deployment or hitting
a road obstacle, data that will assist in
understanding how a vehicle’s systems performed.
The EDR is designed to record data related to
vehicle dynamics and safety systems for a short
period of time, typically 30 seconds or less. The
EDR in this vehicle is designed to record such data
as:
How various systems in your vehicle were oper-
ating;
Whether or not the driver and passenger safety
belts were buckled/fastened;
How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
How fast the vehicle was traveling.
WARNING!
Modifications to any part of the air bag system
could cause it to fail when you need it. You could
be injured if the air bag system is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or
the upper passenger side of the instrument
panel. Do not modify the front fascia/bumper,
vehicle body structure, or add aftermarket side
steps or running boards.
It is dangerous to try to repair any part of the air
bag system yourself. Be sure to tell anyone who
works on your vehicle that it has an air bag
system.
Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or
may not function properly if modifications are
made. Take your vehicle to an authorized dealer
for any air bag system service. If your seat,
including your trim cover and cushion, needs to
be serviced in any way (including removal or
loosening/tightening of seat attachment bolts),
take the vehicle to an authorized dealer. Only
manufacturer approved seat accessories may
be used. If it is necessary to modify the air bag
system for persons with disabilities, contact an
authorized dealer.

Air Bag Warning Light
The Air Bag Warning Light will turn on for four to
eight seconds as a bulb check when the ignition
switch is first placed in the ON/RUN mode. If the
light is either not on during starting, stays on, or
turns on while driving, have the system inspected
at an authorized dealer as soon as possible. After
the bulb check, this light will illuminate with a
single chime when a fault with the Air Bag System
has been detected. It will stay on until the fault is
removed. If the light comes on intermittently or
remains on while driving, have an authorized
dealer service the vehicle immediately
Ú page 250.
Defroster
Check operation by selecting the defrost mode and
place the blower control on high speed. You should
be able to feel the air directed against the
windshield. See an authorized dealer for service if
your defroster is inoperable.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nut/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
ONLY use the driver’s side floor mat on the
driver’s side floor area. To check for interfer -
ence, with the vehicle properly parked with the
engine off, fully depress the accelerator, the
brake, and the clutch pedal (if present) to
check for interference. If your floor mat inter -
feres with the operation of any pedal, or is not
secure to the floor, remove the floor mat from
the vehicle and place the floor mat in your
trunk.
ONLY use the passenger’s side floor mat on
the passenger’s side floor area.
ALWAYS make sure objects cannot fall or slide
into the driver’s side floor area when the
vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
WARNING!
NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners are
secure to the vehicle carpet. Fully depress
each pedal to check for interference with the
accelerator, brake, or clutch pedals then
re-install the floor mats.
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,

Sealing A Tire With Tire Service Kit
Whenever You Stop To Use Tire Service Kit:
1. Pull over to a safe location and turn on the vehicle’s Hazard Warning Flashers.
2. Verify that the valve stem (on the wheel with the deflated tire) is in a position that is near to
the ground. This will allow the Tire Service Kit
Hose to reach the valve stem and keep the Tire
Service Kit flat on the ground. This will provide
the best positioning of the kit when injecting
the sealant into the deflated tire and running
the air pump. Move the vehicle as necessary to
place the valve stem in this position before
proceeding.
3. Place the transmission in PARK (P) and cycle the ignition in the OFF position.
4. Apply the parking brake.
Setting Up To Use Tire Service Kit:
1. Uncoil the Sealant Hose and then remove the cap from the fitting at the end of the hose.
2. Place the Tire Service Kit flat on
the ground next to the deflated tire. 3. Remove the cap from the valve stem and then
screw the fitting at the end of the Sealant Hose
onto the valve stem.
4. Uncoil the Power Plug and insert
the plug into the vehicle’s 12 Volt
power outlet.
NOTE:Do not remove foreign objects (e.g., screws or
nails) from the tire.
Injecting Tire Service Kit Sealant Into The
Deflated Tire:
1. Always start the vehicle before
turning the Tire Service Kit on.
2. Ensure the Mode Select Knob is to
the Sealant Mode position.
3. After pushing the Power Button,
the sealant (white fluid) will flow from
the Sealant Bottle through the
Sealant Hose and into the tire.
NOTE:Sealant may leak out through the puncture in the
tire. If the sealant (white fluid) does not flow within
0 – 10 seconds through the Sealant Hose:
1. Push the Power Button to turn the Tire Service
Kit off. Disconnect the Sealant Hose from the
valve stem. Make sure the valve stem is free
of debris. Reconnect the Sealant Hose to the
valve stem. Check that the Mode Select Knob
is in the Sealant Mode position and not Air
Mode. Push the Power Button to turn the Tire
Service Kit on.
2. Connect the Power Plug to a different 12 Volt power outlet in your vehicle or another vehicle,
if available. Make sure the vehicle is running
before turning the Tire Service Kit on.
3. The Sealant Bottle may be empty due to previous use. Call for assistance.
If the sealant (white fluid) does flow through the
Sealant Hose:
1. Continue to operate the pump
until sealant is no longer flowing
through hose (typically takes
30 - 70 seconds). As the sealant
flows through the Sealant Hose, the Pressure
Gauge can read as high as 70 psi (4.8 Bar).
The Pressure Gauge will decrease quickly
from approximately 70 psi (4.8 Bar) to the
actual tire pressure when the Sealant Bottle
is empty.

2. The pump will start to inject air into
the tire immediately after the
Sealant Bottle is empty. Continue to
operate the pump and inflate the tire
to the cold tire inflation pressure found on the
tire and loading information label located in
the driver-side door opening. Check the tire
pressure by looking at the Pressure Gauge.
If the tire does not inflate to at least 26 psi
(1.8 Bar) pressure within 15 minutes:
The tire is too badly damaged. Do not attempt to
drive the vehicle further. Call for assistance.
If the tire inflates to the recommended pressure
or is at least 26 psi (1.8 Bar) pressure within
15 minutes:
NOTE:If the tire becomes overinflated, push the Deflation
Button to reduce the tire pressure to the recom -
mended inflation pressure before continuing.
1. Push the Power Button to turn the
Tire Service Kit off.
2. Remove the speed limit label from
the Tire Service Kit and place sticker
on the steering wheel. 3. Immediately disconnect the Sealant Hose
from the valve stem, reinstall the cap on the
fitting at the end of the hose, and place the Tire
Service Kit in the vehicle storage location.
Drive Vehicle: Immediately after injecting sealant and
inflating the tire, drive the vehicle 5 miles
(8 km) or 10 minutes to ensure distribution of the Tire Service Kit Sealant
within the tire. Do not exceed 50 mph (80 km/h). After Driving:
Pull over to a safe location and turn on the
vehicle’s Hazard Warning Flashers.
Verify that the valve stem (on the wheel with the
deflated tire) is in a position that is near to the
ground. This will allow the Tire Service Kit Hose
to reach the valve stem and keep the Tire
Service Kit flat on the ground. This will provide
the best positioning of the kit when injecting the
sealant into the deflated tire and running the air
pump. Move the vehicle as necessary to place
the valve stem in this position before
proceeding.
Place the transmission in PARK (P) and cycle the
ignition in the OFF position.
Apply the parking brake.
NOTE:If tire has improper inflation follow the steps below
1. Uncoil the Sealant Hose, and then remove the
cap from the fitting at the end of the hose.
2. Place the Tire Service Kit flat on
the ground next to the deflated tire.
3. Remove the cap from the valve stem, and then screw the fitting at the end of the Sealant Hose
onto the valve stem.
WARNING!
The Tire Service Kit is not a permanent flat tire
repair. Have the tire inspected and repaired or
replaced after using the Tire Service Kit. Do not
exceed 50 mph (80 km/h) until the tire is
repaired or replaced. Failure to follow this
warning can result in injuries that are serious or
fatal to you, your passengers, and others around
you. Have the tire checked as soon as possible
at an authorized dealer.
