200 SAFETY
6. Push the “ESC Off” button located in the lower switchbank below the climate control four times within 20
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an addi -
tional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was completed properly, the “ESC Off
Indicator Light” will blink several times to confirm HSA
is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Traction Control System (TCS)
This system 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
engine power to provide enhanced acceleration and stability.
A feature of the TCS, Brake Limited Differential (BLD), func -
tions similar 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 engine
power to be applied to the wheel that is not spinning. BLD
may remain enabled even if TCS and ESC are in a reduced
mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of the
vehicle under various driving conditions. ESC corrects for
oversteering or understeering of the vehicle by applying the
brake of the appropriate wheel(s) to assist in counteracting
the oversteer or understeer condition. Engine power may
also be reduced to help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle path
intended by the driver and compares it to the actual path of
the vehicle. When the actual path does not match the
intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or understeer
condition.
• Oversteer — when the vehicle is turning more than appro
-
priate for the steering wheel position.
• Understeer — when the vehicle is turning less than appro -
priate for the steering wheel position.

SAFETY 205
wheel lift occurring during severe or evasive driving maneu-
vers; it cannot prevent wheel lift due to other factors, such as
road conditions, leaving the roadway, or striking objects or
other vehicles.
NOTE:
ERM is disabled anytime the ESC is in “Full Off” mode (if
equipped). Refer to “Electronic Stability Control (ESC)” in
this section for a complete explanation of the available ESC
modes.Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an excessively
swaying trailer and will take the appropriate actions to
attempt to stop the sway. TSC will become active automati
-
cally once an excessively swaying trailer is recognized.
NOTE:
TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer Towing” in
“Starting And Operating” for further information.
When TSC is functioning, the “ESC Activation/Malfunction
Indicator Light” will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” or “Full
Off” modes.
WARNING!
Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or roll overs, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.
WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

208 SAFETY
Feedback To The Driver
The instrument cluster has an HDC icon and the HDC switch
has an LED icon, which offers feedback to the driver about
the state HDC is in.
• The cluster icon and switch lamp will illuminate andremain on solid when HDC is enabled or activated. This is
the normal operating condition for HDC.
• The cluster icon and switch lamp will flash for several seconds then extinguish when the driver pushes the HDC
switch but enable conditions are not met.
• The cluster icon and switch lamp will flash for several seconds then extinguish when HDC disables due to excess
speed.
• The cluster icon and switch lamp will flash when HDC deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.AUXILIARY DRIVING SYSTEMS
Blind Spot Monitoring (BSM) — If Equipped
The Blind Spot Monitoring (BSM) system uses two
radar-based sensors, located inside the taillights, to detect
highway licensable vehicles (automobiles, trucks, motorcy -
cles, etc.) that enter the blind spot zones from the rear/front/
side of the vehicle.
Rear Detection Zones
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is
responsible for maintaining a safe vehicle speed.

SAFETY 209
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 or REVERSE and enters stand-by mode when the
vehicle is in PARK.
The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the outside rear view mirror and extends
approximately 10 ft (3 m) beyond the rear 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.
NOTE:
• The BSM system DOES NOT alert the driver about rapidlyapproaching vehicles that are outside the detection zones.
• The Blind Spot Monitoring (BSM) system may experience drop outs (blinking on and off) of the side mirror Warning
Indicator lamps when a motorcycle or any small object
remains at the side of the vehicle for extended periods of
time (more than a couple of seconds). The vehicle’s taillights, 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 taillights with foreign objects (bumper stickers, bicycle
racks, etc.).
Radar Sensor Locations
If the system detects degraded performance due to contami -
nation or foreign objects, a message will warn you of a
blocked sensor and the warning indicators in side view
mirrors will be on. The warning indicators will remain illu-
minated until blockage clearing conditions are met. First

210 SAFETY
clear the taillights around the sensors of the blockage. After
removing the blockage, the following procedure can be used
to reset the system:
• Cycle the ignition from ON to OFF and then back ON.
If the blockage message is still present after cycling the igni-
tion and driving in traffic, check again for a blockage.
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 and reducing the radio volume. Refer to “Modes Of
Operation” in this section for further information.
Warning Light Location 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

214 SAFETY
(5 km/h), to objects moving a maximum of approximately
20 mph (32 km/h), such as in parking lot situations.
NOTE:
In a parking lot situation, oncoming vehicles can be obscured
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.
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.Modes Of Operation
Three selectable modes of operation are available in the
Uconnect System.
Refer to “Uconnect Settings” in “Multimedia” for further
information.
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
WARNING!
Rear Cross Path Detection (RCP) is not a back up 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.

216 SAFETY
Forward Collision Warning (FCW) With Mitigation — If
Equipped
The Forward Collision Warning (FCW) system provides the
driver with audible, visual warnings (within the instrument
cluster display), and may apply a haptic warning in the form
of a brake jerk, to warn the driver when it detects a potential
frontal collision. The warnings are intended to provide the
driver with enough time to react, avoid or mitigate the
potential collision.
NOTE:
FCW monitors the information from the forward looking
sensors as well as Electronic Brake Controller (EBC), to calcu-
late 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 as well as
a possible haptic warning in the form of a brake jerk.
If the driver does not take action based upon these progres-
sive 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. If a FCW with Mitigation event begins at a speed below
32 mph (52 km/h), the system may provide the maximum
braking possible to mitigate the potential forward collision.
If the Forward Collision Warning with Mitigation event
stops the vehicle completely, the system will hold the vehicle
at standstill for two seconds and then release the brakes.
FCW Message
When the system determines a collision with the vehicle in
front of you is no longer probable, the warning message will
be deactivated.

222 SAFETY
• The TPMS is not a substitute for proper tire maintenance,and it is the driver’s responsibility to maintain correct tire
pressure using an accurate tire pressure gauge, even if
under-inflation has not reached the level to trigger illumi -
nation of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.
Example: Tire Pressure Monitor Display
The Tire Pressure Monitor System (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 monthly and to maintain the
proper pressure.
The TPMS consists of the following components:
• Receiver module
• Four tire pressure monitoring sensors
• Various tire pressure monitoring system messages, which
display in the instrument cluster
• Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime will
sound when tire pressure is low in one or more of the
four active road tires. In addition, the instrument cluster will
display a graphic showing the pressure values of each tire
with the low tire pressure values in a different color. An
"Inflate to XX" message will also be displayed.
