The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in forward
gear; vehicle backing uphill is in REVERSE gear).
HSA will work in REVERSE gear and all forward
gears. The system will not activate if the trans -
mission is in PARK or NEUTRAL. For vehicles
equipped with a manual transmission, if the
clutch is pressed, HSA will remain active.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current settings in the instrument
cluster display see Ú page 64.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of
each of the driven wheels. If wheel spin is
detected, the TCS may apply brake pressure to the
spinning wheel(s) and/or reduce vehicle power to
provide enhanced acceleration and stability. A
feature of the TCS, Brake Limited Differential (BLD)
functions similarly to a limited slip differential and
controls the wheel spin across a driven axle. If one
wheel on a driven axle is spinning faster than the
other, the system will apply the brake of the
spinning wheel. This will allow more vehicle torque
to be applied to the wheel that is not spinning. BLD
may remain enabled even if TCS and ESC are in
reduced modes.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BS M) —
I
F EQUIPPED
BSM uses two radar sensors, located inside the
rear fascia/bumper, to detect highway licensable
vehicles (automobiles, trucks, motorcycles, etc.)
that enter the blind spot zones from the rear/front/
side of the vehicle.
Rear Detection Zones

When the vehicle is started, the BSM Warning Light
will momentarily illuminate in both outside
rearview mirrors to let the driver know that the
system is operational. The BSM system sensors
operate when the vehicle is in any forward gear
and enters standby mode when the vehicle is in
PARK.
The BSM detection zone covers approximately one
lane width on both sides of the vehicle, 10 ft (3 m).
The zone length starts at the outside mirror and
extends approximately 20 ft (6 m) beyond the rear
fascia/bumper of the vehicle. The BSM system
monitors the detection zones on both sides of the
vehicle when the vehicle speed reaches
approximately 6 mph (10 km/h) or higher and will
alert the driver of vehicles in these areas.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA is
not a substitute for active driving involvement. It
is always the driver’s responsibility to be
attentive to distance to other vehicles, people,
and objects, and most importantly brake
operation to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle. Failure to
follow these warnings can result in a collision or
serious personal injury.

22_FD_OM_EN_USC_t.book Page 178

SAFETY179
NOTE:
The BSM system DOES NOT alert the driver
about rapidly approaching vehicles that are
outside the detection zones.
If a trailer is connected to the vehicle, it is neces -
sary to deactivate BSM system manually by
settings menu to avoid a misdetection
Ú page 123.
The area on the rear fascia/bumper where the
radar sensors are located must remain free of
snow, ice, and dirt/road contamination so that the
BSM system can function properly. Do not block
the radar sensors located on the rear fascia/
bumper with foreign objects (bumper stickers,
bicycle racks, etc.).

Rear Sensor Locations
The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM warning
light located in the outside mirrors, in addition to
sounding an audible (chime) alert (whenever the
turn signal is activated) and reducing the radio
volume Ú
page 181.

BSM Warning Light

The BSM system monitors the detection zone from
three different entry points (side, rear, front) while
driving to see if an alert is necessary. The BSM
system will issue an alert during these types of
zone entries.
Entering From The Side
Vehicles that move into your adjacent lanes from
either side of the vehicle.
Side Monitoring

Entering From The Rear
Vehicles that come up from behind your vehicle on
either side and enter the rear detection zone with
a relative speed of less than 31 mph (50 km/h).

Rear Monitoring

22_FD_OM_EN_USC_t.book Page 179

SAFETY181
Rear Cross Path (RCP)
RCP is intended to aid the driver when backing out
of parking spaces where their vision of oncoming
vehicles may be blocked. Proceed slowly and
cautiously out of the parking space until the rear
end of the vehicle is exposed. The RCP system will
then have a clear view of the cross traffic and if an
oncoming vehicle is detected, alert the driver.

RCP Detection Zones

RCP monitors the rear detection zones on both
sides of the vehicle, for objects that are moving
toward the side of the vehicle with a minimum
speed of approximately 1 mph (2 km/h), to objects
moving a maximum of approximately 22 mph
(35 km/h), such as in parking lot situations.
When RCP is on and the vehicle is in REVERSE, the
driver is alerted using both the visual and audible
alarms, including reducing the radio volume.
NOTE:In a parking lot situation, oncoming vehicles can be
blocked by vehicles parked on either side. If the
sensors are blocked by other structures or
vehicles, the system will not be able to alert the
driver.
Blind Spot Modes
Blind Spot has three selectable modes of
operation that are available in the Uconnect
system.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the BSM
system will provide a visual alert in the appropriate
side view mirror based on a detected object.
However, when the system is operating in Rear
Cross Path (RCP) mode, the system will respond with both visual and audible alerts when a
detected object is present. Whenever an audible
alert is requested, the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime
mode, the BSM system will provide a visual alert in
the appropriate side view mirror based on a
detected object. If the turn signal is then activated,
and it corresponds to an alert present on that side
of the vehicle, an audible chime will also be
sounded. Whenever a turn signal and detected
object are present on the same side at the same
time, both the visual and audible alerts will be
issued. In addition to the audible alert, the radio (if
on) will also be muted.
NOTE:Whenever an audible alert is requested by the
BSM system, the radio is also muted.
When the system is in RCP, the system will respond
with both visual and audible alerts when a
detected object is present. Whenever an audible
alert is requested, the radio is also muted. Turn/
hazard signal status is ignored; the RCP state
always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off, there will be
no visual or audible alerts from either the BSM or
RCP systems.
WARNING!
RCP is not a backup aid system. It is intended to
be used to help a driver detect an oncoming
vehicle in a parking lot situation. Drivers must be
careful when backing up, even when using RCP.
Always check carefully behind your vehicle, look
behind you, and be sure to check for
pedestrians, animals, other vehicles,
obstructions, and blind spots before backing up.
Failure to do so can result in serious injury or
death.

NOTE:The BSM system will store the current operating
mode when the vehicle is shut off. Each time the
vehicle is started the previously stored mode will
be recalled and used.
Blind Spot Monitoring Fault Warnings
Blinded Sensor
In the case of a blinded sensor:
BSM Mirror Warning Lights are turned on contin -
uously.
An instrument cluster message will display
“Blind Spot Monitoring Unavailable - Wipe Rear
Bumper Corners.”
NOTE:The rear fascia/bumper must be clean and free of
any obstructing debris.
System Not Available
In the case of the system being temporarily
unavailable:
BSM Mirror Warning Lights are turned on contin -
uously.
An instrument cluster message will display
“Blind Spot Monitoring Temporarily Unavail -
able.” In the case of the system being completely
unavailable:
A chime will turn on.
An instrument cluster message will display
“Blind Spot Monitoring Unavailable - Service
Required.”
NOTE:The vehicle must be taken to the nearest autho
-
rized dealer for service.
FULL BRAKE CONTROL SYSTEM WITH
M
ITIGATION
The Full Brake Control system with Mitigation
provides the driver with audible warnings (through
the radio), visual warnings (within the instrument
cluster display), and may apply a brake jerk to warn
the driver when it detects a potential frontal
collision. The warnings and limited braking are
intended to provide the driver with enough time to
react, avoid or mitigate the potential collision.
NOTE:
The Full Brake Control system monitors the
information from the forward looking sensors as
well as the Electronic Brake Controller (EBC), to
calculate the probability of a forward collision.
When the system determines that a forward
collision is probable, the driver will be provided with audible and visual warnings and may
provide a brake jerk warning.
If the driver does not take action based upon
these progressive warnings, then the system
will provide a limited level of active braking to
help slow the vehicle and mitigate the potential
forward collision. If the driver reacts to the warn
-
ings by braking and the system determines that
the driver intends to avoid the collision by
braking but has not applied sufficient brake
force, the system will compensate and provide
additional brake force as required.
After the end of the intervention of automatic
braking, the transmission may remain in last gear
stored; therefore the car could lurch forward, once
the brakes release a few seconds later. If the Full
Brake Control system event stops the vehicle
completely, the system will hold the vehicle at
standstill for two seconds and then release the
brakes.
If a Full Brake Control system event begins at a
speed below 26 mph (42 km/h), the system may
provide the maximum braking possible to mitigate
the potential forward collision. If the Full Brake
Control system event stops the vehicle completely,
the system will hold the vehicle at standstill for two
seconds and then release the brakes.

22_FD_OM_EN_USC_t.book Page 182

184SAFETY
By changing the option to "Near", the system will
warn the driver of a possible accident with the
vehicle ahead of it when the latter is a reduced
distance. This setting offers a reaction time to the
driver lower than the settings "Medium" and "Far",
in the case of a potential accident, which will
provide a more dynamic driving experience.
The setting of the sensitivity of the system is
maintained in memory when the engine is
switched off.
Full Brake Control System Limited Warning
If the instrument cluster display reads “Brake
Control Limited Functionality” or “Brake Control
Limited Functionality Clean Front Windshield”
momentarily, there may be a condition that limits
Full Brake Control system 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 Full Brake Control System Warning
If the system turns off, and the instrument cluster
display displays “Service Brake Control”.
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. “Brake Control Front Radar Sensor Temporarily
Blocked” Warning
The “Brake Control Front Radar Sensor
Temporarily Blocked” warning will display when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility,
such as in snow or heavy rain. The system may also
become temporarily blinded due to obstructions,
such as mud, dirt or ice. In these cases, the
instrument cluster display will display “Brake
Control Front Radar Sensor Temporarily Blocked”
and the system will deactivate.
The “Brake Control Front Radar Sensor
Temporarily Blocked” message can sometimes be
displayed while driving in highly reflective areas
(i.e. tunnels with reflective tiles, or ice and snow).
The system will recover after the vehicle has left
these areas. Under rare conditions, when the radar
is not tracking any vehicles or objects in its path
this warning may temporarily occur.
If weather conditions are not a factor, the driver
should examine the sensor. It may require cleaning
or removal of an obstruction. The sensor is located
behind the lower grille. In absence of visible
obstructions on the fascia/bumper, it could be
necessary to wipe off the radar directly on the
surface, after having the radar cover removed. It’s
recommended that an authorized dealer performs
this operation.
NOTE:
If the “Brake Control Front Radar Sensor Tempo
-
rarily Blocked” message occurs frequently (e.g.
more than once on every trip) without any snow,
rain, mud, or other obstruction, have the radar
sensor realigned at an authorized dealer.
Installing a snow plow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit Full Brake Control system operation.
Precautions While Driving With Full Brake
Control System
In certain driving conditions, such as:
Driving in the vicinity of a curve
Small vehicles and/or not aligned to the lane
Lane changing of other vehicles
Passing of vehicles in an oncoming intersection
The intervention of the system could be
unexpected or delayed. The driver must therefore
always pay particular attention, while maintaining
control of the car to drive in complete safety.

22_FD_OM_EN_USC_t.book Page 184

SAFETY185
Driving In The Vicinity Of A Curve
Entering or exiting a large curve, the system could
detect the presence of a vehicle that is in front of
the car, but that does not preside in the same lane.
In cases such as this, the system might respond.

Driving In The Vicinity Of A Curve

Small Vehicles And/Or Not Aligned To The Lane
The system is not able to detect the presence of
vehicles that are in front of the car but placed
outside the field of action of the radar sensor and
could therefore not react in the presence of small
vehicles such as bicycles or motorcycles.
Small Vehicles And/Or Not Aligned To The Lane

Lane Changing Of Other Vehicles
Vehicles that suddenly change lanes, while
standing in the traffic lane of their car and inside
the field of action of the radar sensor may cause
the intervention of the system.

Lane Changing Of Other Vehicles
Passing Of Vehicles In An Oncoming Intersection
The system could temporarily react to a vehicle
that crossed the range of the radar sensor, in an
oncoming intersection.

Passing Of Vehicles In An Oncoming Intersection

TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold tire pressure.
The tire pressure will vary with temperature by
about 1 psi (7 kPa) for every 12° F (6.5° C). This
means that when the outside temperature
decreases, the tire pressure will decrease. Tire
pressure should always be set based on cold
inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than
6

22_FD_OM_EN_USC_t.book Page 185

186SAFETY
1 mile (1.6 km) after a three hour period. The cold
tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire
sidewall. The tire pressure will also increase as the
vehicle is driven, this is normal and there should be
no adjustment for this increased pressure.
See Ú page 269 on how to properly inflate the
vehicle's tires.
The TPMS will warn the driver of a low tire pressure
if the tire pressure falls below the low pressure
warning limit for any reason, including low
temperature effects, or natural pressure loss
through the tire.
The TPMS will continue to warn the driver of low
tire pressure as long as the condition exists, and
will not turn off until the tire pressure is at or above
the recommended cold tire pressure on the
placard. Once the low tire pressure warning (Tire
Pressure Monitoring System Warning Light)
illuminates, you must increase the tire pressure to
the recommended cold tire pressure in order for
the Tire Pressure Monitoring System Warning Light
to turn off. The system will automatically update
and the Tire Pressure Monitoring System Warning
Light will turn off once the system receives the
updated tire pressures. The vehicle may need to be
driven for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive this
information. For example, your vehicle may have a
recommended cold (parked for more than three
hours) tire pressure of 30 psi (207 kPa). If the
ambient temperature is 68° F (20° C) and the
measured tire pressure is 27 psi (186 kPa), a
temperature drop to 20° F (-7° C) will decrease
the tire pressure to approximately 23 psi
(159 kPa). This tire pressure is sufficiently low
enough to turn on the Tire Pressure Monitoring
System Warning Light. Driving the vehicle may
cause the tire pressure to rise to approximately
27 psi (186 kPa), but the Tire Pressure Monitoring
System Warning Light will still be on. In this
situation, the Tire Pressure Monitoring System
Warning Light will turn off only after the tires are
inflated to the vehicle’s recommended cold tire
pressure value Ú
page 297.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warnings have been established for the
tire size equipped on your vehicle. Undesir -
able system operation or sensor damage may
result when using replacement equipment
that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor
damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. After
using an aftermarket tire sealant it is recom -
mended that you take your vehicle to an
authorized dealership to have your sensor
function checked.
After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the Tire Pres -
sure Monitoring System sensor.

22_FD_OM_EN_USC_t.book Page 186

SAFETY187
NOTE:
The TPMS is not intended to replace normal tire
care and maintenance, or to provide warning of
a tire failure or condition.
The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi -
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate tire gauge, even if underinflation has not
reached the level to trigger illumination of the
Tire Pressure Monitoring System Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
Base System
This is the TPMS Warning Light located in
the instrument cluster.
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle regularly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module.
Four Tire Pressure Monitoring System sensors.
Tire Pressure Monitoring System Warning Light.
TIRE PRESSURE MONITORING SYSTEM LOW
PRESSURE WARNINGS
The Tire Pressure Monitoring System Warning Light
will illuminate in the instrument cluster, an
acoustic signal will be activated, and the “Check
left or right front/rear tire” text message will
display when one or more of the four active road
tire pressures are low. Should this occur, you
should stop as soon as possible, check the
inflation pressure of each tire on your vehicle, and
inflate each tire to the vehicle’s recommended
cold placard pressure value. The system will
automatically update and the Tire Pressure
Monitoring Warning Light will extinguish once the
updated tire pressures have been received. The
vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this
information.
CHECK TPMS WARNINGS
The Tire Pressure Monitoring System Warning Light
will flash on and off for 75 seconds and remain on
solid when a system fault is detected, an audible
chime will be activated and the “Service Tire
Pressure Monitoring System” text message will
display. If the ignition is cycled, this sequence will
repeat providing the system fault still exists. The
Tire Pressure Monitoring System Warning Light will
turn off when the fault condition no longer exists. A
system fault can occur with any of the following
scenarios:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors.
Installing some form of aftermarket window
tinting that affects radio wave signals.
Snow or ice around the wheels or wheel hous
-
ings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors.
NOTE:Your vehicle may be equipped with a compact
spare wheel and tire assembly.
The compact spare tire does not have a Tire
Pressure Monitoring System sensor. Therefore,
the TPMS will not monitor the tire pressure in
the compact spare tire.

Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic
parts of the air bag system whenever the
ignition switch is in the AVV/START or
MAR/ACC/ON/RUN position. If the ignition switch
is in the STOP/OFF/LOCK position the air bag
system is not on and the air bags will not inflate.
The ORC contains a backup power supply system
that may deploy the air bag system even if the
battery loses power or it becomes disconnected
prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch is
in the MAR/ACC/ON/RUN position. After the
self-check, the Air Bag Warning Light will turn off. If
the ORC detects a malfunction in any part of the
system, it turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime will
sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could affect
the air bag system. The diagnostics also record the
nature of the malfunction. While the air bag system is designed to be maintenance free, if any of the
following occurs, have an authorized dealer
service the air bag system immediately.The Air Bag Warning Light does not come on
during the four to eight seconds when the igni
-
tion switch is first in the MAR/ACC/ON/RUN
position.
The Air Bag Warning Light remains on after the
four to eight-second interval.
The Air Bag Warning Light comes on intermit -
tently or remains on while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant
Restraint Controller (ORC) may also be disabled. In
this condition the air bags may not be ready to
inflate for your protection. Have an authorized
dealer service the air bag system immediately.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have the
air bag system to protect you in a collision. If the
light does not come on as a bulb check when the
ignition is first turned on, stays on after you start
the vehicle, or if it comes on as you drive, have
an authorized dealer service the air bag system
immediately.
