90GETTING TO KNOW YOUR INSTRUMENT PANEL
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction warning light after replacing
one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to
function properly.Low Fuel Warning Light
When the fuel level reaches
approximately 1.9 gal (7.13 L), this
light will turn on and a single chime
will sound.
Anti-Lock Brake (ABS) Warning Light
This warning light monitors the
Anti-Lock Brake System (ABS). The
light will turn on when the ignition is
placed in the ON/RUN or ACC/ON/
RUN position and may stay on for as long as four
seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the brake
system is not functioning and service is
required as soon as possible. However, the
conventional brake system will continue to
operate normally, assuming the Brake Warning
Light is not also on.
If the ABS light does not turn on when the
ignition is placed in the ON/RUN or ACC/ON/
RUN position, have the brake system inspected
by an authorized dealer.
Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to
indicate a fault in the Forward
Collision Warning System. Contact an
authorized dealer for service.
Refer to "Forward Collision Warning (FCW)" in
"Safety" for further information.
Service AWD Warning Light — If Equipped
This warning light will turn on to
indicate the All Wheel Drive (AWD)
system is not functioning properly and
that service is required. Contact an
authorized dealer.
LaneSense Warning Light — If Equipped
The LaneSense system provides the
driver with visual and steering torque
warnings when the vehicle starts to
drift out of its lane unintentionally
without the use of a turn signal.
When the LaneSense system senses a lane
drift situation, the LaneSense indicator
changes from solid green to solid yellow.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established 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. 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 recommended that you take your
vehicle to an authorized dealer to have your
sensor function checked.

SAFETY97
Electronic Brake Force Distribution (EBD)
The Electronic Brake Force Distribution (EBD)
function manages the distribution of the
braking torque between the front and rear axles
by limiting braking pressure to the rear axle.
This is done to prevent overslip of the rear
wheels to avoid vehicle instability, and to
prevent the rear axle from entering the
Anti-Lock Brake System (ABS) before the front
axle.
Electronic Roll Mitigation (ERM)
The Electronic Roll Mitigation (ERM) system
anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and
the speed of the vehicle. When ERM determines
that the rate of change of the steering wheel
angle and vehicle’s speed are sufficient to
potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine
power to lessen the chance that wheel lift will
occur. ERM can only reduce the chance of
wheel lift occurring during severe or evasive
driving maneuvers; 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.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) 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 appropriate for the steering wheel posi
-
tion.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel posi -
tion.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will start
to flash as soon as the ESC system becomes
active. The “ESC Activation/Malfunction
Indicator Light” also flashes when the TCS is
active. If the “ESC Activation/Malfunction
Indicator Light” begins to flash during
acceleration, ease up on the accelerator and
apply as little throttle as possible. Be sure to
adapt your speed and driving to the prevailing
road conditions.
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.

102SAFETY
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 torque to be applied to the wheel that is
not spinning. BLD may remain enabled even if
TCS and ESC are in a reduced mode.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. The BSM system sensors
operate when the vehicle is in any forward gear
or REVERSE.
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 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 rapidly approaching vehicles that are
outside the detection zones.

20_LX_OM_EN_USC_t.book Page 102

SAFETY107
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:
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 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 miti -
gate the potential forward collision. If the driver
reacts to the warnings 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 Forward Collision Warning with
Mitigation event begins at a speed below
20 mph (32 km/h), the system may provide the
maximum or partial braking to mitigate the potential forward collision. If the Forward Colli
-
sion 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.
NOTE:
The minimum speed for FCW activation is
1 mph (2 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.
It is unsafe to test the FCW system. To
prevent such misuse of the system, after four
Active Braking events within an ignition cycle,
the Active Braking portion of FCW will be
deactivated until the next ignition 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
unnecessary warnings to the surroundings.
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.

STARTING AND OPERATING163
(Continued)
The following conditions will also deactivate the
Speed Control without erasing the set speed
from memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs
ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the
driving convenience provided by cruise control
while traveling on highways and major
roadways. However, it is not a safety system
and not designed to prevent collisions. Speed
Control function performs differently. Please
refer to the proper section within this chapter.
ACC will allow you to keep cruise control
engaged in light to moderate traffic conditions
without the constant need to reset your cruise
control. ACC utilizes a radar sensor and a
forward facing camera designed to detect a
vehicle directly ahead of you. NOTE:
If the sensor does not detect a vehicle ahead
of you, ACC will maintain a fixed set speed.
If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or accelerate
(not to exceed the original set speed) auto
-
matically to maintain a preset following
distance, while matching the speed of the
vehicle ahead.
The Cruise Control system has two control
modes:

Adaptive Cruise Control mode for maintaining
an appropriate distance between vehicles.
Normal (Fixed Speed) Cruise Control mode for
cruising at a constant preset speed. For addi -
tional information, refer to “Normal (Fixed
Speed) Cruise Control Mode” in this section.

NOTE:
Normal (Fixed Speed) Cruise Control will not
react to preceding vehicles. Always be aware of
the mode selected. You can change the mode by using the Cruise
Control buttons. The two control modes
function differently. Always confirm which mode
is selected.
WARNING!
Adaptive Cruise Control (ACC) is a conve
-
nience system. It is not a substitute for
active driver involvement. It is always the
driver’s responsibility to be attentive of
road, traffic, and weather conditions,
vehicle speed, distance to the vehicle
ahead; and, most importantly, brake opera -
tion 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 and death or serious personal
injury.

STARTING AND OPERATING169
instrument cluster displays the “Sensed Vehicle
Indicator” icon, and the system adjusts vehicle
speed automatically to maintain the distance
setting, regardless of the set speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed
above the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages. (Refer to the infor -
mation on ACC Activation).
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:
The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE” will flash in the instrument cluster display and a chime will
sound while ACC continues to apply its
maximum braking capacity.

Brake Alert

NOTE:
The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the
Forward Collision Warning system is applying
the brakes autonomously.
OVERTAKE AID
When driving with ACC engaged and following a
vehicle, the system will provide an additional
acceleration up to the ACC set speed to assist in
passing the vehicle. This additional acceleration
is triggered when the driver utilizes the left turn
signal (Lane Change Assist feature included) and will only be active when passing on the left
hand side. Switching lanes will not impact the
ACC system if the driver is already traveling at
the set speed.
ACC OPERATION AT STOP
If the ACC system brings your vehicle to a
standstill while following a target vehicle, if the
target vehicle starts moving within two seconds
of your vehicle coming to a standstill, your
vehicle will resume motion without the need for
any driver action.
If the target vehicle does not start moving within
two seconds of your vehicle coming to a
standstill, the ACC with Stop system will cancel
and the brakes will release. A cancel message
will display on the instrument cluster display
and produce a warning chime. Driver
intervention will be required at this moment.
While ACC with Stop is holding your vehicle at a
standstill, if the driver seat belt is unbuckled or
the driver door is opened, the ACC with Stop
system will cancel and the brakes will release. A
cancel message will display on the instrument
cluster display and produce a warning chime.
Driver intervention will be required at this
moment.
