different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all fourtires and wheels are the same
size. Never drive the vehicle with
different sized wheels and tiresinstalled.
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. Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and parking brake
warning lights are displayed.

Hill-Start Assist Control (HAC) (if equipped)
A vehicle has the tendency to slide
backwards on a steep slope, before
depressing the accelerator after a
stop. The HAC prevents the vehicle
from sliding backwards by automati-
cally operating the brake systems for
about 2 seconds. The brake systemsare automatically released, when the
accelerator pedal is depressed.
Information
 The HAC does not operate when the gear is in P (Park) or N (Neutral).
 The HAC activates even when the ESC (Electronic Stability Control) is
off. However, it does not activate,
when the ESC does not normally
operate.
i
NOTICE
If ESC indicator light ( ) or
EPS warning light ( ) stays
on or blinks, your vehicle may
have a malfunction with the
VSM system. When the warninglight illuminates we recommend
that the vehicle be checked by
an authorized HYUNDAI dealer
as soon as possible.
WARNING
The HAC is activated only for
about 2 seconds, so alwaysdepress the accelerator pedal
to begin driving upwards after astop.

Prerequisite for activation
The AEB gets ready to be activated, when the AEB is selected on the
LCD display, and when the followingprerequisites are satisfied.
- The ESC (Electronic StabilityControl) is activated.
- To enable the system to detect pedestrians ahead, the vehicle
driving speed must be between 8km/h – 70 km/h (5 mph – 45 mph).
- To enable the system to detect a vehicle ahead, the vehicle driving
speed must be between 8 km/h –180 km/h (5 mph – 110 mph).
When traveling above 80 km/h (50mph), 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.
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.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
POWER button to the ON
position. The driver can deac-
tivate the AEB by cancelingthe 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

5-52
Driving your vehicle
- If your vehicle drives slower than70 km/h (45 mph) with a pedestri-
an in front, the driving speed may
abruptly decrease. When your
vehicle drives faster than 70 km/h
(45 mph) with a pedestrian in
front, the AEB does not operate.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
pedal, or when the driver abruptly
operates 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 drivershould hold the responsibility
to safely drive and control the
vehicle.

Detecting pedestrians (if equipped)
The sensor may be limited when:
The pedestrian is not fully detected by the camera recognition system,
for example, if the pedestrian is
leaning over or is not fully walking
upright
The pedestrian is moving very quickly or appears abruptly in the
camera detection area
The pedestrian is wearing clothing that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-tion system
The outside lighting is too bright (e.g. when driving in bright sunlight
or in sun glare) or too dark (e.g.
when driving on a dark rural roadat night)
It is difficult to detect and distin- guish the pedestrian from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd
There is an item similar to a per- son’s body structure The pedestrian is small
The pedestrian has impaired
mobility
The sensor recognition is limited
It is difficult to detect and distin- guish the pedestrian from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd
Information
In some instances, the AEB system
may be cancelled when subjected to
electromagnetic interference.
i
Do not use the Autonomous
Emergency Braking system
when towing a vehicle.Application of the AEB sys-
tem while towing may
adversely affect the safety of
your vehicle or the towing
vehicle.
Use extreme caution when 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. (Continued)
(Continued)
The AEB system is designed to detect and monitor the
vehicle ahead or detect a
pedestrian in the roadway
through radar signals and
camera recognition. It is not
designed to detect bicycles,
motorcycles, or smaller
wheeled objects such as lug-
gage bags, shopping carts, or
strollers.
Never try to test the operation
of the AEB system. Doing so
may cause severe injury ordeath.

Driving your vehicle
The Lane Keeping Assist System
detects lane markers on the road,
and assists the driver's steering 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 acoustic
warning, while applying a slight
counter-steering torque, trying to
prevent the vehicle from moving out
of its lane.

OAEE056013L The Lane Keeping Assist
System is not a substitute for
safe driving practices, but a
convenience function only. It isthe 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 KeepingAssist System (LKAS):
The steering wheel is not con-
tinuously controlled so if the
vehicle speed is at a higher
rate when leaving a lane the
vehicle may not be controlled
by the system.
Do not steer the steering
wheel suddenly when thesteering wheel is being assist-
ed by the system.
(Continued)
(Continued)
LKAS prevents 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 becautious when the system
cancels, does not operate ormalfunctions.
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 that
reflect light on the dashboardwhile driving.

(Continued)
Do not place any accessories
near the rearview mirror.
Do not tint the windshield glass.
The operation of the LKAS
may be affected by several
factors including environmen-
tal conditions that affect theability of the camera to detect
the lanes in front of you. It isthe responsibility of the driver
to pay careful attention to the
roadway and to maintain the
vehicle in its intended lane atall times.
Always have your hands on the steering wheel while the
LKAS system is activated. If
you continue to drive with
your hands off the steering
wheel after the "Keep handson steering wheel" warning
message appears, the system
will will stop controlling thesteering wheel.
Always be cautious when using the system.
