Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering maneuvers.
ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle's brakes
and intervenes in the engine man-
agement system to assist the driver
with keeping the vehicle on the
intended path. It is not a substitute
for safe driving practices. Always
adjust your speed and driving to the
road conditions.
ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately three seconds. After both
lights go off, the ESC is enabled.
When operating
When the ESC is in oper-
ation, the ESC indicator
light blinks:
When you apply your brakes under conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This
is normal and it means your ESC is
active.
When the ESC activates, the engine may not respond to the
accelerator as it does under rou-
tine conditions.
If the Smart Cruise Control was in use when the ESC activates, the
Smart Cruise Control automatically
disengages. The Smart Cruise
Control can be reengaged when
the road conditions allow. See
"Smart Cruise Control System"
later in this chapter. (if equipped)
When moving out of the mud or driving on a slippery road, the
engine RPM (revolutions per
minute) may not increase even if
you press the accelerator pedal
deeply. This is to maintain the sta-
bility and traction of the vehicle and
does not indicate a problem.
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will
not prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning
on wet surfaces can result in
severe accidents.

Vehicle Stability Management
(VSM)
The Vehicle Stability Management
(VSM) is a function of the Electronic
Stability Control (ESC) system. It
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tires can suddenly become uneven.
VSM operation
VSM ON condition
The VSM operates when:
The Electronic Stability Control(ESC) is on.
Vehicle speed is approximately above 9 mph (15 km/h) on curve
roads.
Vehicle speed is approximately above 12 mph (20 km/h) when the
vehicle is braking on rough roads.
When operating
When you apply your brakes under
conditions which may activate the
ESC, you may hear sounds from the
brakes, or feel a corresponding sen-
sation in the brake pedal. This is nor-
mal and it means your VSM is active.
The VSM does not operate when:
Driving on a banked road suchas gradient or incline.
Driving rearward.
ESC OFF indicator light is on.
MDPS (Motor-Driven Power Steering) warning light ( ) is
on or blinks.
NOTICE
Take the following precautions
when using the Vehicle Stability
Management (VSM):
ALWAYS check the speed andthe distance to the vehicle
ahead. The VSM is not a sub-
stitute for safe driving prac-
tices.
Never drive too fast for the road conditions. The VSM sys-
tem will not prevent acci-
dents. Excessive speed in bad
weather, slippery and uneven
roads can result in severe
accidents.
WARNING

Driving your vehicle
The driving mode automatically changes to SMART SPORT, when
you abruptly accelerate the vehicle
or repetitively operate the steering
wheel (Your driving is categorized
to be sporty.). In this mode, your
vehicle drives in a lower gear for
abrupt accelerating/decelerating
and increases the engine brake
performance.
You may still sense the engine braking performance, even when
you release the accelerator pedal
in SMART SPORT mode. It is
because your vehicle remains in
lower gear over a certain period of
time for next acceleration. Thus, it
is a normal driving situation, not
indicating any malfunction.
The driving mode automatically changes to SMART SPORT mode
only in harsh driving situations. In
most of the normal driving situa-
tions, the driving mode sets to be
either in SMART ECO mode or in
SMART NORMAL mode.
Limitation of SMART mode
The SMART mode may be limited in
following situations. (The OFF indica-
tor illuminates in those situations.)
The driver manually moves theshift lever :
It deactivates SMART mode. The
vehicle drives, as the driver manu-
ally moves the shift lever.
The cruise control is activated : The cruise control system may
deactivate the SMART mode when
the vehicle is controlled by the set
speed of the smart cruise control
system. (SMART mode is not
deactivated just by activating the
smart cruise control system.)
The transmission oil temperature is either extremely low or extremely
high :
The SMART mode can be active in
most of the normal driving situa-
tions. However, an extremely high/
low transmission oil temperature
may temporarily deactivate the
SMART mode, because the trans-
mission condition is out of normal
operation condition.

SPORT mode
SPORT mode manages
the driving dynamics by
automatically adjusting
the steering effort, and
the engine and transmission control
logic for enhanced driver perform-
ance.
When SPORT mode is selected by pressing the DRIVE MODE button,
the SPORT indicator (yellow color)
will illuminate.
Whenever the engine is restarted, the Drive Mode will revert back to
SMART mode. If SPORT mode is
desired, re-select SPORT mode
from the DRIVE MODE button.
When SPORT mode is activated: - The engine rpm will tend toremain raised over a certain
length of time even after releas-
ing the accelerator
- Upshifts are delayed when accel- erating
Information
In SPORT mode, the fuel efficiency
may decrease.
Virtual engine sounds are gener-
ated from the exterior amplifiers.
Pay extreme caution while replac-
ing amplifier components. The
use of any after-market compo-
nents or speakers may damage
the exterior amplifiers causing the
virtual engine sounds not to prop-
erly operate.
ECO mode
When the Drive Mode is
set to ECO mode, the
engine and transmission
control logic are changed
to maximize fuel efficiency.
When ECO mode is selected by pressing the DRIVE MODE button,
the ECO indicator (green color) will
illuminate.
If the vehicle is set to ECO mode, when the engine is turned OFF
and restarted the Drive Mode set-
ting will remain in ECO mode.
Information
Fuel efficiency depends on the driver's
driving habit and road condition.

5-48
Driving your vehicle
When ECO mode is activated:
The acceleration response may beslightly reduced if the accelerator
pedal is depressed moderately.
The air conditioner performance may be limited.
The shift pattern of the automatic transmission may change.
The engine noise may be louder at some automatic transmission
shifts as down-shift requires press-
ing down more on the accelerator.
The above situations are normal
conditions when ECO mode is acti-
vated to improve fuel efficiency.
Limitation of ECO mode operation:
If the following conditions occur while
ECO mode is operating, the system
operation is limited even though
there is no change in the ECO indi-
cator.
When the coolant temperature is low:
The system will be limited until
engine performance becomes nor-
mal.
When driving up a hill: The system will be limited to gain
power when driving uphill because
engine torque is restricted.
When driving the vehicle with the automatic transmission gear shift
lever in manual mode.
The system will be limited accord-
ing to the shift location.
INDIVIDUAL mode
In INDIVIDUAL mode, thedriver can select separate
modes and combine them
on the DIS Navigation
System screen.
- Engine/Transmission:
ECO/SMART
- Steering wheel:COMFORT/SPORT
- Suspension:COMFORT +/
COMFORT/SPORT
- All-Wheel Drive (AWD) system:
ECO/COMFORT/SPORT
For more information, refer to the
separately supplied DIS Navigation
System manual.
When INDIVIDUAL mode is select- ed by pressing the DRIVE MODE
button, the INDIVIDUAL mode indi-
cator (blue color) will illuminate.

The Smart Blind Spot Detection
System detects the front area
through the camera installed on the
upper front windshield and detects
the side/rear areas through radar
sensors.
The Smart Blind Spot Detection
System may activate the Electronic
Stability Control (ESC) in accor-
dance with a colliding possibility with
an approaching vehicle while chang-
ing lanes. It is to lower the colliding
risk or mitigate the colliding damage.
Operating conditions
The system enters the ready status,
when the following conditions are
satisfied with the smart blind system
in the ON position:
- Vehicle speed is between 40 mph
and 110 mph (60 km/h and 180
km/h).
- The system detects both of the lane lines.
- An approaching vehicle is detected next to/behind your vehicle.
Activation (with braking per-formance)
The Smart Blind Spot Detection
System may apply braking power,
when an approaching vehicle is
detected within a certain distance
next to/behind your vehicle.
It gently applies braking power on
the tire, which is located in the oppo-
site side of the possibly-colliding
point. The instrument cluster will
inform the driver of the system acti-
vation.
The Smart Blind Spot Detection
System is automatically deactivated,
when the vehicle drives a certain dis-
tance away, when the vehicle direc-
tion is changed against the possible-
colliding point, when the steering
wheel is abruptly moved, or when the
brake pedal is depressed.

AEB Warning Message and
System Control
The AEB produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, insufficient braking dis-
tance, or pedestrian detection. Also,
it controls the brakes in accordance
with the collision risk levels.
Forward Warning (1st warning)
This initial warning message
appears on the LCD display and the
head up display (if equipped) with a
warning chime.
The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward
Collision Warning include Early,
Normal or Late initial warning time.
OHI056048L
Completely stop the vehicleon a safe location before
operating the switch on the
steering wheel to activate/
deactivate the AEB system.
The AEB automatically acti- vates upon placing the Engine
Start/Stop button to the ON
position. The driver can deac-
tivate the AEB by canceling
the system setting on the LCD
display.
The AEB automatically deacti- vates upon canceling the ESC
(Electronic Stability Control).
When the ESC is canceled,
the AEB cannot be activated
on the LCD display.

Driving your vehicle
Collision Warning (2ndwarning)
This warning message appears on
the LCD display and the head up dis-
play (if equipped) with a warning
chime.
Additionally, some vehicle system
intervention occurs by the engine
management system to help decel-
erate the vehicle.
- If a vehicle is detected, your vehiclespeed may decelerate moderately.
Emergency braking (3rdwarning)
This warning message appears on
the LCD display and the head up dis-
play (if equipped) with a warning
alarm. Additionally, some vehicle system
intervention occurs by the engine
management system to help decel-
erate the vehicle.
- If the detected vehicle in front is
driving slower than 50 mph (80
km/h) your vehicle speed may
decelerate sharply to avoid a colli-
sion. If the detected vehicle in front
is driving faster than 50 mph (80
km/h), your vehicle speed may
decelerate moderately.
- If your vehicle drives slower than 45 mph (70 km/h) with a pedestri-
an in front, the driving speed may
abruptly decrease. When your
vehicle drives faster than 45 mph
(70 km/h) with a pedestrian in
front, the AEB does not operate.
Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
The AEB provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the acceleraor
pedal, or when the driver abruptly
operates the steering wheel.
The AEB braking control is auto- matically canceled, when risk fac-
tors disappear.

Driving your vehicle
The Lane Keeping Assist System
helps detect lane markers on the
road, and assists the driver's steer-
ing to help keep the vehicle between
lanes.
When the system detects the vehicle
straying from its lane, it alerts the
driver with a visual and steering
wheel vibration warning, while apply-
ing a slight counter-steering torque,
to try to prevent the vehicle from
moving out of its lane.

The lane keeping assist system
is not a substitute for safe driv-
ing practices, but a conven-
ience function only. It is the
responsibility of the driver to
always be aware of the sur-
rounding and steer the vehicle.
WARNING
Take the following precautions
when using the Lane Keeping
Assist System (LKAS):
The steering wheel is not con-
tinuously controlled so if the
vehicle speed is at a higher
speed when leaving a lane the
vehicle may not be able to be
controlled by the system.
Do not steer the steering wheel suddenly when the
steering wheel is being assist-
ed by the system.
LKAS helps prevent the driver from moving out of the lane
unintentionally by assisting
the driver's steering. However,
the driver should not solely
rely on the system but always
pay attention on the steering
wheel to stay in the lane.
Always check the road condi- tion and surroundings and be
cautious when the system
cancels, does not operate or
malfunctions.
The system detects lane lines and controls the steering
wheel by a camera, therefore,
if the lane lines are hard to
detect, the system may not
work properly.
Please refer to "Limitations of
the system".
Do not attempt to repair the LKAS camera and do not
remove any parts.
Do not place objects on the dashboard that reflect light
such as mirrors, white paper,
etc. The system may malfunc-
tion if the sunlight is reflected.
