7. Rotate the steering wheel back to center
and then an additional slightly more than
one-half turn to the right.
8. Place 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.
Rain Brake Support (RBS)
Rain Brake Support (RBS) may improve braking
performance in wet conditions. It will
periodically apply a small amount of brake
pressure to remove any water buildup on the
front brake rotors. It functions when the
windshield wipers are in LO or HI speed. When
RBS is active, there is no notification to the
driver and no driver interaction is required.
Ready Alert Braking (RAB)
Ready Alert Braking (RAB) may reduce the time
required to reach full braking during emergency
braking situations. It anticipates when an
emergency braking situation may occur by monitoring how fast the throttle is released by
the driver. The Electronic Brake Controller (EBC)
will prepare the brake system for a panic stop.
Traction Control System (TCS)
The Traction Control System (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 engine power to provide
enhanced acceleration and stability. A feature
of the TCS, Brake Limited Differential (BLD),
functions 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 reduced modes.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BS M) — IF
E
QUIPPED
The Blind Spot Monitoring (BSM) system uses
two radar sensors, located inside the rear
bumper fascia, 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.
Automatic Transmission Vehicles
The BSM system sensors operate when the
vehicle is in any forward gear or REVERSE.

20_LA_OM_EN_USC_t.book Page 100

SAFETY101
Manual Transmission Vehicles
The BSM system sensors operate when the
vehicle is in any gear.

BSM Warning Light

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
rearview 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 rapidly approaching vehicles that are
outside the detection zones.
The BSM system detection zone DOES NOT
change if your vehicle is towing a trailer.
Therefore, visually verify the adjacent lane is
clear for both your vehicle and trailer before
making a lane change. If the trailer or other
object (i.e., bicycle, sports equipment)
extends beyond the side of your vehicle, this
may result in the BSM warning light
remaining illuminated the entire time the
vehicle is in a forward gear.
The 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 area on the rear fascia 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 area of the rear fascia where the radar
sensors are located with foreign objects
(bumper stickers, bicycle racks, etc.).
Sensor Location

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” for further information.
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.

102SAFETY
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

Overtaking Traffic
If you pass another vehicle slowly (with a
relative speed of less than 15 mph (24 km/h))
and the vehicle remains in the blind spot for
approximately 1.5 seconds, the warning light
will be illuminated. If the difference in speed
between the two vehicles is greater than
15 mph (24 km/h), the warning light will not
illuminate.
Overtaking/Approaching

The BSM system is designed not to issue an
alert on stationary objects such as guardrails,
posts, walls, foliage, berms, etc. However,
occasionally the system may alert on such
objects. This is normal operation and your
vehicle does not require service.

Overtaking/Passing

20_LA_OM_EN_USC_t.book Page 102

SAFETY103
The BSM system will not alert you of objects that
are traveling in the opposite direction of the
vehicle in adjacent lanes.

Opposing Traffic
Rear Cross Path — If Equipped
The Rear Cross Path (RCP) feature 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 3 mph (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 alerts, including reducing the radio
volume so that the alert can be better heard.
WARNING!
The Blind Spot Monitoring system is only an
aid to help detect objects in the blind spot
zones. The BSM system is not designed to
detect pedestrians, bicyclists, or animals.
Even if your vehicle is equipped with the BSM
system, always check your vehicle’s mirrors,
glance over your shoulder, and use your turn
signal before changing lanes. Failure to do so
can result in serious injury or death.
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.

FORWARD COLLISION WARNING (FCW)
O
PERATION - IF EQUIPPED
The Forward Collision Warning (FCW) system
provides the driver with audible warnings, visual
warnings (within the instrument cluster display),
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 the Electronic
Stability Control (ESC) System, 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.
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.
NOTE:
The minimum speed for FCW activation is
5 mph (10 km/h).
The FCW alerts may be triggered on objects
other than vehicles such as guard rails or
sign posts based on the course prediction.
This is expected and is a part of normal FCW
activation and functionality.
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
unnecessary warnings to the surroundings.
Turning FCW On Or Off
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.
The Forward Collision activation/deactivation is
located in "Uconnect Settings" under "Safety
And Driving Assistance". Forward Collision can
be checked or unchecked.
When FCW is selected off, there will be an "FCW
OFF" icon that appears in the instrument cluster
display.
Changing the FCW status to off prevents the
system from warning you of a possible collision
with the vehicle in front of you.
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.

20_LA_OM_EN_USC_t.book Page 105

106SAFETY
NOTE:
The FCW system’s default state is on. The FCW
system state is kept in memory from one igni -
tion cycle to the next. If the system is turned off,
it will remain off when the vehicle is restarted.
NOTE:
FCW system is temporarily turned off when ESC
“Full Off” mode is active.
Changing FCW Status
The FCW Sensitivity settings are programmable
through the Uconnect System. Refer to
“Uconnect Settings” in “Multimedia” for further
information.
The default status of FCW is the “Far” setting in
the “On” setting. This allows the system to warn
you of a possible collision with the vehicle in
front of you when you are farther away and it
applies limited braking. This gives you the most
reaction time to avoid a possible collision.
Changing the FCW status to the “Near” setting,
allows the system to warn you of a possible
collision with the vehicle in front of you when
you are much closer. This setting provides less
reaction time than the “Far” setting, which
allows for a more dynamic driving experience. NOTE:
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 rate of speed.
FCW will be disabled like ACC, with the
unavailable screens.
Service FCW Warning
If the system turns off, and the instrument
cluster display reads:
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.

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 placard
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 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.
Refer to “Tires” in “Servicing And Maintenance”
for information on how to properly inflate the
vehicle’s tires. The tire pressure will also
increase as the vehicle is driven — this is normal
and there should be no adjustment for this
increased pressure.
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 and 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 placard
pressure. Once the low tire pressure warning
(TPMS Warning Light) illuminates, you must
increase the tire pressure to the recommended
cold placard pressure in order for the TPMS
Warning Light to turn off. The system will automatically update and the
TPMS 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.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off.

For example, your vehicle may have a
recommended cold (parked for more than three
hours) placard 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
(158 kPa). This tire pressure is sufficiently low
enough to turn on the TPMS Warning Light.
Driving the vehicle may cause the tire pressure
to rise to approximately 27 psi (186 kPa), but the
TPMS Warning Light will still be on. In this
situation, the TPMS Warning Light will turn off
only after the tires are inflated to the vehicle’s
recommended cold placard pressure value.

108SAFETY
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 pres -
sure gauge while adjusting your tire pressure.
Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency 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 responsi -
bility to maintain correct tire pressure using
an accurate tire pressure gauge, even if
under-inflation has not reached the level to
trigger illumination of the TPMS Warning
Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor the
actual tire pressure in the tire.
Premium System
The Tire Pressure Monitoring 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 TPMS Warning 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.
CAUTION!
The TPMS has been optimized for the orig -
inal equipment tires and wheels. TPMS
pressures and warning have been estab -
lished for the tire size equipped on your
vehicle. Undesirable system operation or
sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. The TPM
sensor is not designed for use on after -
market wheels and may contribute to a
poor overall system performance or sensor
damage. Customers are encouraged to use
OEM wheels to assure proper TPM feature
operation.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. After
using an aftermarket tire sealant it is
recommended that you take your vehicle to
your authorized dealer to have your sensor
function checked.
After inspecting or adjusting the tire pres -
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could
damage the TPMS sensor.

20_LA_OM_EN_USC_t.book Page 108

SAFETY109
In addition, the instrument cluster will display
an “Inflate to XX” message and a graphic
showing the pressure values of each tire with
the low tire pressure values shown in a different
color.

Tire Pressure Monitoring Display

Should this occur, you should stop as soon as
possible and inflate the tires with a low pressure
condition (those shown in a different color in the
instrument cluster graphic) to the vehicle’s
recommended cold placard pressure inflation
value as shown in the “Inflate to XX” message.
Once the system receives the updated tire
pressures, the system will automatically
update, the graphic display in the instrument
cluster will change color back to the original
color, and the TPMS Warning Light will turn off. 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.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off.

Low Tire Pressure Monitoring Display

Service Tire Pressure System Warning
If a system fault is detected, the Tire Pressure
Monitoring System (TPMS) Warning Light will
flash on and off for 75 seconds and then remain
on solid. The system fault will also sound a
chime. In addition, the instrument cluster will
display a "Service Tire Pressure System" message for a minimum of five seconds and
then display dashes (- -) in place of the pressure
value to indicate which sensor is not being
received.
If the ignition switch is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the TPMS
Warning Light will no longer flash, and the
"Service Tire Pressure System" message will no
longer display, and a pressure value will display
in place of the dashes. A system fault can occur
due to any of the following:
Signal interference due to electronic devices
or driving next to facilities emitting the same
radio frequencies as the TPM sensors
Accumulation of snow or ice around the
wheels or wheel housings
Using tire chains on the vehicle
Using wheels/tires not equipped with TPM
sensors

110SAFETY
Vehicles With Compact Spare

1. The compact spare tire or non-matching
full size does not have a Tire Pressure
Monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the
compact or non-matching full size spare
tire.

2. If you install the compact or non-matching full size spare tire in place of a road tire that
has a pressure below the low-pressure
warning limit, upon the next ignition key
cycle, the TPMS Warning Light will remain
on and a chime will sound. In addition, the
graphic in the instrument cluster will still
display a different color pressure value and
an "Inflate to XX" message.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the
TPMS Warning Light will flash on and off for
75 seconds and then remain on solid. In
addition, the instrument cluster will display
a “Service Tire Pressure System” message
for five seconds and then display dashes
(- -) in place of the pressure value. 4. For each subsequent ignition key cycle, a
chime will sound, the TPMS Warning Light
will flash on and off for 75 seconds and then
remain on solid, and the instrument cluster
will display a “Service Tire Pressure System”
message for five seconds and then display
dashes (- -) in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of
the compact spare or non-matching full
size, the TPMS will update automatically. In
addition, the TPMS Warning Light will turn
off and the graphic in the instrument cluster
will display a new pressure value instead of
dashes (- -), as long as no tire pressure is
below the low-pressure warning limit in any
of the four active road tires. 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.
TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (TPMS)
can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and
tire assemblies that do not have TPMS sensors,
such as when installing winter wheel and tire
assemblies on your vehicle. To deactivate the TPMS, first replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
(TPM) sensors. Then, drive the vehicle for
20 minutes above 15 mph (24 km/h). The
TPMS will chime, the TPMS Warning Light will
flash on and off for 75 seconds and then remain
on. The instrument cluster will display the
“Service Tire Pressure System” message and
then display dashes (--) in place of the pressure
values.
Beginning with the next ignition cycle, the TPMS
will no longer chime or display the “Service Tire
Pressure System” message in the instrument
cluster but dashes (--) will remain in place of the
pressure values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPM sensors. Then, drive the
vehicle for up to 20 minutes above 15 mph
(24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for
75 seconds and then turn off. The instrument
cluster will display the “Service Tire Pressure
System” message and then display pressure
values in place of the dashes.
