Driving your vehicle
Good Braking Practices
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop
as quickly if the brakes are wet. Wet
brakes may cause the vehicle to pull
to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns
to normal, taking care to keep the
vehicle under control at all times. If
the braking action does not return to
normal, stop as soon as it is safe to
do so and call an authorized Dealer
of Genesis Brand Products for assis-
tance.
DO NOT drive with your foot resting
on the brake pedal. Even light, but
constant pedal pressure can result in
the brakes overheating, brake wear,
and possibly even brake failure.If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe location.
Keep your foot firmly on the brake
pedal when the vehicle is stopped to
prevent the vehicle from rolling for-
ward.
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Move
the shift lever into the P (Park)
position, then apply the parking
brake, and place the Engine
Start/Stop button in the OFF
position.
Vehicles with the parking brake
not fully engaged are at risk for
moving inadvertently and caus-
ing injury to yourself or others.

SMART mode
SMART mode selects the
proper driving mode
among ECO, NORMAL,
and SPORT by judging
the driver’s driving habits
(i.e. mild or dynamic)
from the brake pedal
depression or the steer-
ing wheel operation.
Press the DRIVE MODE button to activate SMART mode. When
SMART mode is activated, the indi-
cator illuminates on the instrument
cluster.
The indicator illuminates in green, when the driver's driving is catego-
rized to be mild. It illuminates in
white, when the driver's driving is
categorized to be normal. It illumi-
nates in yellow, when the driver's
driving is categorized to be dynam-
ic during abrupt braking or sharp
curving.
The vehicle starts in SMART mode again, when the engine was turned
OFF in SMART mode.
SMART mode automatically con- trols the vehicle driving, such as
gear shifting patterns, engine
torque, riding quality (if equipped
with the electronic suspension sys-
tem), and power distribution (if
equipped with the All-Wheel Drive
(AWD) system), in accordance with
the driver’s driving habits.Information
• When you mildly drive the vehiclein SMART mode, the driving mode
changes to ECO mode to improve
fuel efficiency. However, the actual
fuel efficiency may differ in accor-
dance with your driving situations
(i.e. upward/downward slope, vehi-
cle deceleration/acceleration).
• When you dynamically drive the vehicle in SMART mode by abrupt-
ly decelerating or sharply turning,
the driving mode changes to
SPORT mode. However, it may
adversely affect fuel economy.
Various driving situations, which
you may encounter in SMART
mode
The driving mode automaticallychanges to ECO mode after a cer-
tain period of time, when you gen-
tly depress the accelerator pedal
(Your driving is categorized to be
mild.).
The driving mode automatically changes from SMART ECO mode
to SMART NORMAL mode after a
certain period of time, when you
sharply or repetitively depress the
accelerator pedal.
The driving mode automatically changes to SMART NORMAL
mode with the same driving pat-
terns, when the vehicle starts to
drive on an upward slope of a cer-
tain angle. The driving mode auto-
matically returns to SMART ECO
mode, when the vehicle enters a
leveled road.
i

5-46
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.

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)
or TCS (Traction Control
System). 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 brake pedal,
or when the driver abruptly oper-
ates the steering wheel.
The AEB braking control is auto- matically canceled, when risk fac-
tors disappear.

The AEB is only a supplemen-tal system for the driver's con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on the AEB
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed.
In certain instances and under certain driving condi-
tions, the AEB system may
activate prematurely. This ini-
tial warning message appears
on the LCD display with a
warning chime.
Also, in certain instances the
front radar sensor or camera
recognition system may not
detect the vehicle or pedestri-
an ahead. The AEB system
may not activate and the
warning message will not be
displayed.
If there is a malfunction with the AEB system, the automat-
ic emergency braking is not
applied even though the brak-
ing system is operating nor-
mally.
(Continued)
(Continued)
The AEB system operatesonly to detect vehicles or
pedestrians in front of the
vehicle.
The AEB system does not
operate when the vehicle is in
reverse.
The AEB system is not
designed to detect other
objects on the road such as
animals.
The AEB system does not
detect cross traffic vehicles
that are approaching.
The AEB system cannot
detect the driver approaching
the side view of a parked vehi-
cle (for example on a dead
end street.)
In these cases, you must
maintain a safe braking dis-
tance, and if necessary,
depress the brake pedal to
reduce the driving speed in
order to maintain a safe dis-
tance.WARNING

Driving on a curve
The performance of the AEB system
may be limited when driving on a
curved road.
In certain instances on a curved
road, the AEB system may activate
prematurely.
Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
traveling on a curved road.
In these cases, the driver must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
The AEB system may recognize a
vehicle in the next lane when driving
on a curved road.In this case, the system may unnec-
essarily alarm the driver and apply
the brake.
Always pay attention to road and
driving conditions, while driving. If
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
Also, when necessary depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
Driving on a slope
The performance of the AEB
decreases while driving upward or
downward on a slope, not recogniz-
ing the vehicle in front in the same
lane.
It may unnecessarily produce the
warning message and the warning
alarm, or it may not produce the
warning message and the warning
alarm at all.
When the AEB suddenly recognizes
the vehicle in front while passing
over a slope, you may experience
sharp deceleration.
Always keep your eyes forward while
driving upward or downward on a
slope, and, if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain distance.

Driving your vehicle
Changing lanes
When a vehicle changes lanes in
front of you, the AEB system may not
immediately detect the vehicle, espe-
cially if the vehicle changes lanes
abruptly. In this case, you must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
When driving in stop-and-go traffic,
and a stopped vehicle in front of you
merges out of the lane, the AEB sys-
tem may not immediately detect the
new vehicle that is now in front of
you. In this case, you must maintain
a safe braking distance, and if neces-
sary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance. Detecting the vehicle in front of you
If the vehicle in front of you has cargo
that extends rearward from the cab,
or when the vehicle in front of you
has higher ground clearance, addi-
tional special attention is required.
The AEB system may not be able to
detect the cargo extending from the
vehicle.
In these instances, you must main-
tain a safe braking distance from the
rearmost object, and if necessary,
depress the brake pedal to reduce
your driving speed in order to main-
tain distance.
