178SAFETY
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.

182SAFETY
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.

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.
