Driving your vehicle
The ESC OFF indicator light comes
on when the ESC is turned off from
the User Settings Mode.
ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud by temporarily
stopping operation of the ESC to
maintain wheel torque.
To turn ESC off while driving, press
the ESC OFF button while driving on
a flat road surface.
✽ ✽
NOTICE
Turning the ESC off does not affect
ABS or standard brake system oper-
ation.
When the ESC is blinking, this
indicates the ESC is active:
Drive slowly and NEVER
attempt to accelerate. NEVER
turn the ESC off while the ESC
indicator light is blinking or you
may lose control of the vehicle
resulting in an accident.
WARNING
Driving with varying tire or
wheel sizes may cause the ESC
system to malfunction. When
replacing tires, make sure they
are the same size as your origi-
nal tires for this vehicle.
CAUTION
To prevent damage to the trans-
mission:
Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and brake
warning lights are displayed.
The repairs would not be cov-
ered by the vehicle warranty.
Reduce engine power and do
not spin the wheel(s) exces-
sively while these lights are
displayed.
When operating the vehicle
on a dynamometer, ensure the
ESC is turned off (ESC OFF
light illuminated).

Vehicle Stability Management
(VSM) (if equipped)
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.
✽ ✽
NOTICE
The VSM does not operate when:
• Driving on a banked road such as
gradient or incline
• Driving rearward.
• ESC OFF indicator light is on.
• EPS (Electric Power Steering)
warning light ( ) is on or blinks.
5Take the following precautions
when using the Vehicle Stability
Management (VSM):
ALWAYS check the speed and
the 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 with wheels and tires
with different sizes may cause
the ESC system to malfunction.
Before replacing tires, make
sure all four tires and wheels
are the original size. Never drive
the vehicle with different sized
tires and wheels than what is
recommended.
CAUTION
If ESC indicator light ( ) or
EPS warning light ( ) stays on
or blinks, your vehicle may have
a malfunction with the VSM sys-
tem. When the warning light illu-
minates we recommend that the
vehicle be checked by an
authorized retailer of Genesis
Branded products as soon as
possible.

Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
backwards when starting a vehicle
from a stop on a hill. The system
operates the brakes automatically for
approximately 2 seconds and releas-
es the brake when the accelerator
pedal is depressed or after 2 sec-
onds.
✽ ✽
NOTICE
• The HAC does not operate when
the shift lever is in P (Park) or N
(Neutral)
• The HAC activates even though
the ESC (Electronic Stability
Control) is off but does not acti-
vate when the ESC has malfunc-
tioned.
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 retailer
of Genesis Branded products for
assistance.
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. Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC acti-
vates only for approximately 2
seconds.
WARNING
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.

Prerequisite for activation
The AEB gets ready to be activated,
when the AEB is selected on the
LCD display, and when the following
prerequisites are satisfied.
- The ESC (Electronic Stability
Control ) is on.
- To enable the system to detect
pedestrians ahead, the vehicle
driving speed must be between 5
mph – 45 mph (8 km/h – 70 km/h).
- To enable the system to detect a
vehicle ahead, the vehicle driving
speed must be between 5 mph –
110 mph (8 km/h – 180 km/h).
When traveling above 50 mph (80
km/h), the AEB system only initiates
partial braking. This is to prevent
unintended full braking to stop in the
middle of the highway.
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.Completely stop the vehicle
on 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.
WARNING

Additionally, some vehicle system
intervention occurs by the engine
management system to help decel-
erate the vehicle.
- Your vehicle speed may decelerate
moderately.
- The AEB system limitedly controls
the brakes to preemptively mitigate
impact in a collision.
Emergency braking (3rdwarning)
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.

Brake operation
In an urgent situation, the braking
system 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 accelerator,
or when the driver abruptly oper-
ates the steering wheel.
The AEB brake control is automat-
ically canceled, when risk factors
disappear.The driver should always use
extreme caution while operating
the vehicle, whether or not there
is a warning message or alarm
from the AEB system.CAUTION
The braking control cannot
completely stop the vehicle nor
avoid all collisions. The driver
should hold the responsibility
to safely drive and control the
vehicle.
WARNING
The AEB system logic operates
within certain parameters, such
as the distance from the vehicle
or pedestrian ahead, the speed
of the vehicle ahead, and the
driver's vehicle speed. Certain
conditions such as inclement
weather and road conditions
may affect the operation of the
AEB system.
WARNING
Never deliberately drive danger-
ously to activate the system.
WARNING

System malfunction
Check AEB system
When the AEB is not working prop-
erly, the AEB warning light ( )
will illuminate and the warning
message will appear for a few sec-
onds. After the message disap-
pears, the master warning light
( ) will illuminate. In this case,
we recommend you to have the
vehicle inspected by an authorized
retailer of Genesis Branded prod-
ucts.
The AEB warning message may
appear along with the illumination
of the ESC (Electronic Stability
Control) warning light.

(Continued)
If the front bumper becomes
damaged in the area around
the radar sensor, the AEB sys-
tem may not operate properly.
We recommend you to have
the vehicle inspected by an
authorized retailer of Genesis
Branded products.
Use only Genesis/Hyundai
Part to repair or replace a
damaged sensor or sensor
cover. Do not apply paint to
the sensor cover.
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.

Limitations of the system
The Autonomous Emergency
Braking (AEB) system is designed to
monitor the vehicle ahead or a
pedestrian in the roadway through
radar signals and camera recogni-
tion to warn the driver that a collision
is imminent, and if necessary, apply
emergency braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle or pedestrian
ahead. In these cases, the AEB sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
AEB operation may be limited.
Driving your vehicle
(Continued)
If there is a malfunction with
the AEB system, the
autonomous emergency brak-
ing is not applied even though
the braking system is operat-
ing normally.
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
The AEB system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
The AEB system may not acti-
vate if the driver applies the
brake pedal to avoid a colli-
sion.
The AEB system operates
only 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 main-
tain a safe braking distance,
and if necessary depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance.

Detecting vehicles
The sensor may be limited when:
The radar sensor or camera is
blocked with a foreign object or
debris
Inclement weather such as heavy
rain or snow obscures the field of
view of the radar sensor or camera
There is interference by electro-
magnetic waves
There is severe irregular reflection
from the radar sensor
The vehicle in front is too small to
be detected by the camera recog-
nition system (for example a motor-
cycle or a bicycle, etc.)
The vehicle in front is an oversize
vehicle or trailer that is too big to
be detected by the camera recog-
nition system (for example a tractor
trailer, etc.)
The driver's field of view is not well
illuminated (either too dark or too
much reflection or too much back-
light that obscures the field of view)
The vehicle in front does not have
their rear lights properly turned ON The outside brightness changes
suddenly, for example when enter-
ing or exiting a tunnel
The vehicle in front is driving errat-
ically
The vehicle is on unpaved or
uneven rough surfaces, or roads
with sudden gradient changes
The vehicle is moving under
ground level or inside a building
The vehicle is driven near areas
containing metal substances such
as a construction zone, railroad,
etc.- 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 warn-
ing 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.
