Anti-lock Brake System (ABS)
ABS is an electronic braking system
that helps prevent a braking skid.
ABS allows the driver to steer and
brake at the same time.
Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your
brake pressure and do not try to
pump your brakes. Depress your
brake pedal as hard as possible.
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 ABS is
active.
ABS does not reduce the time or dis-
tance it takes to stop the vehicle.
Always maintain a safe distance from
the vehicle in front of you.
ABS will not prevent a skid that
results from sudden changes in
direction, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather con-
ditions.

An Anti-Lock Braking System
(ABS) or an Electronic Stability
Control (ESC) system will not
prevent accidents due to
improper or dangerous driving
maneuvers. Even though vehi-
cle control is improved during
emergency braking, always
maintain a safe distance
between you and objects ahead
of you. Vehicle speeds should
always be reduced during
extreme road conditions. The
braking distance for cars
equipped with ABS or ESC may
be longer than for those without
these systems in the following
road conditions.
Drive your vehicle at reduced
speeds during the following
conditions:
Rough, gravel or snow-cov-
ered roads.
WARNING
On roads where the road sur-
face is pitted or has different
surface height.
Tire chains are installed on
your vehicle.
The safety features of an ABS
or ESC equipped vehicle should
not be tested by high speed
driving or cornering. This could
endanger the safety of yourself
or others.

5-30
ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing wheel movement can still cause
your vehicle to veer into oncoming
traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake sys-
tem may result in a longer stopping
distance than for vehicles equipped
with a conventional brake system.
The ABS warning light ( ) will stay
on for several seconds after the
POWER button is in the ON position.
During that time, the ABS will go
through self-diagnosis and the light
will go off if everything is normal. If
the light stays on, you may have a
problem with your ABS. Contact an
authorized HYUNDAI dealer as soon
as possible.When you drive on a road having
poor traction, such as an icy road,
and apply your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light ( ) may illuminate. Pull
your car over to a safe place and
turn the vehicle off.
Restart the vehicle. If the ABS
warning light is off, then your ABS
system is normal.
Otherwise, you may have a prob-
lem with your ABS system.
Contact an authorized HYUNDAI
dealer as soon as possible.
Information
When you jump start your vehicle
because of a drained battery, the ABS
warning light ( ) may turn on at the
same time. This happens because of
the low battery voltage. It does not
mean your ABS is malfunctioning.
Have the battery recharged before
driving the vehicle.
i
NOTICE
Driving your vehicle
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, contact your
HYUNDAI dealer as soon as
possible.

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 electric vehicle
control 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 POWER button is in the
ON position, the ESC and the ESC
OFF indicator lights illuminate for
approximately three seconds. After
both lights go off, the ESC is
enabled.
OFE058030
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.
WARNING

Driving your vehicle
When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:

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.

cle may not respond to the acceler-
ator as it does under routine condi-
tions.

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 with stop & go sys-
tem" later in this chapter.
ESC OFF condition
To cancel ESC operation :

Press the ESC OFF button briefly.
The ESC OFF indicator light and
message "Traction Control disabled"
will illuminate. In this state, the trac-
tion control function of ESC is dis-
abled, but the brake control function
of ESC still operates.
Press and hold the ESC OFF button
continuously for more than 3 sec-
onds. The ESC OFF indicator light
and message "Traction & Stability
Control disabled" illuminates and a
warning chime sounds. In this state,
both the traction control function of
ESC and the brake control function
of ESC are disabled.
If the POWER button is placed to the
OFF position when ESC is off, ESC
remains off. Upon restarting the vehi-
cle, the ESC will automatically turn
on again.

Driving your vehicle
Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and parking brake
warning lights are displayed.
The repairs would not be cov-
ered by the vehicle warranty.
Reduce vehicle power and do
not spin the wheel(s) excessive-
ly while these lights are dis-
played.
When operating the vehicle on a
dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
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 18 mph (30 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.
i
NOTICE
Take 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 substi-
tute for safe driving practices.
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.

Driving your vehicle
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 5 seconds and releas-
es the brake after 5 seconds or 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 operate nor-
mally.
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. If the braking action does
not return to normal, stop as soon as
it is safe to do so and call an author-
ized HYUNDAI dealer 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.
i
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Shift
to the P (Park) position, then
apply the parking brake, and
place the POWER button in the
OFF position.
Vehicles parked with the park-
ing brake not applied or not
fully engaged may roll inadver-
tently and may cause injury to
the driver and others. ALWAYS
apply the parking brake before
exiting the vehicle.
WARNING
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC acti-
vates only for approximately 5
seconds.

The Forward Collision-Avoidance
Assist (FCA) system is designed to
help detect and monitor the vehicle
ahead or detect a pedestrian or
cyclists in the roadway through radar
signals and camera recognition to
warn the driver that a collision is
imminent, and if necessary, apply
emergency braking.System Setting and Activation
System setting
The driver can activate the FCA by
placing the power button to the ON
position and by selecting on the
AVN screen :
"Vehicle settings →Driver assis-
tance →Forward safety"
- If you select "Active assistance",
the FCA system activates. The
FCA produces warning mes-
sages and warning alarms in
accordance with the collision risk
levels. Also, it controls the brakes
in accordance with the collision
risk levels.
- If you select "Warning Only", the
FCA system activates and pro-
duces only warning alarms in
accordance with the collision risk
levels. You should control the
brake directly because the FCA
system do not control the brake.
- If you select "Off", the FCA sys-
tem deactivates,

Take the following precautions
when using the Forward Collision-
Avoidance Assist (FCA) system:
This system is only a supple-
mental system and it is not
intended to, nor does it replace
the need for extreme care and
attention of the driver. The
sensing range and objects
detectable by the sensors are
limited. Pay attention to the
road conditions at all times.
NEVER drive too fast in accor-
dance with the road condi-
tions or while cornering.
Always drive cautiously to
prevent accidents from any
unexpected and sudden situa-
tions. The Forward Collision-
Avoidance system may not
always stop the vehicle com-
pletely and is only intended to
help mitigate a collision that
is imminent.

Prerequisite for activation
The FCA system is on and ready
when FCA is selected on the AVN
vehicle settings and when the follow-
ing prerequisites are satisfied:
- The ESC (Electronic Stability
Control) is on.
- Driving speed exceeds approxi-
mately 5 mph (8 km/h) (The FCA
is only activated within a certain
speed range.).
- The system detects a pedestrian,
cyclists or a vehicle in front, which
may collide with your vehicle. (The
FCA may not be activated or may
sound a warning alarm in accor-
dance with the driving situation or
vehicle condition.)
If you select "Warning only", the
FCA system activates and pro-
duces only warning alarms in
accordance with the collision risk
levels.
❈The FCA may not operate proper-
ly according to the frontal situa-
tion, the direction of pedestrian or
cyclist and speed.
FCA Warning Message and
System Control
The FCA 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 or cyclists
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 Vehicle set-
tings in the AVN screen. The options
for the initial Forward Collision
Warning include Early or Later initial
warning time.Completely stop the vehicle
on a safe location before
operating the switch on the
steering wheel to activate/
deactivate the FCA system.
The FCA automatically acti-
vates upon placing the
POWER button to the ON
position. The driver can deac-
tivate the FCA by canceling
the system setting on the AVN
screen.
The FCA automatically deacti-
vates upon canceling the ESC
(Electronic Stability Control).
When the ESC is canceled,
the FCA cannot be activated
on the AVN screen. The FCA
warning light will illuminate
which is normal.
