5Driving 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 same
size. Never drive the vehicle with
different sized wheels and tires
installed.
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.
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 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.
Information
The VSM does not operate when:
• Driving on a banked road such as a
gradient or incline.
• Driving in reverse.
• The ESC OFF indicator light is on.
• The EPS (Electric power steering)
warning light ( ) is on or blinks.
i
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.

VSM OFF condition
To cancel VSM operation, press the
ESC OFF button. ESC OFF indicator
light ( ) will illuminate.
To turn on VSM, press the ESC OFF
button again. The ESC OFF indicator
light will go out.Driving with wheels and tires with
different sizes may cause the VSM
system to malfunction. Before
replacing tires, make sure all four
tires and wheels are the same
size. Never drive the vehicle with
different sized tires and wheels
installed.
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 after 2 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.
i
NOTICE
If the ESC indicator light ( ) or
EPS warning light ( ) stays
on or blinks, your vehicle may
have a malfunction with the
VSM system. When the warning
light illuminates, have the vehi-
cle checked by an authorized
HYUNDAI dealer as soon as
possible.
WARNING
Always be ready to depress the
accelerator pedal when starting
off an incline. The HAC activates
only for approximately 2 sec-
onds.

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. 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.

- If you select 'Warning Only', FCA
system activates and produces
only warning alarms in accor-
dance with the collision risk lev-
els. Braking assist will not be
applied in this setting.
- If you select 'Off', FCA system
deactivates,
The warning light illumi-
nates on the instrument
cluster, when you cancel
FCA system. The driver
can monitor the FCA ON/OFF status
on the LCD display. Also, the warning
light illuminates when the ESC
(Electronic Stability Control) is
turned off.
- If the warning light remains ON
when FCA is activated, we recom-
mend that you have the system
checked by an authorized
HYUNDAI dealer. Selecting Warning Timing
The driver can select the initial
warning activation time from the
User Settings in the cluster LCD
display by selecting 'User Settings
→Driver Assistance →Warning
Timing →Normal/Late'.
The options for the initial Forward
Collision Warning includes the fol-
lowing:
- Normal:
When this option is selected, the
initial Forward Collision Warning is
activated sensitively. If you feel the
warning activates too early, set
Forward Collision Warning to
'Late'.Even though, 'Normal' is selected if
the front vehicle suddenly stops
the initial warning activation time
may not seem fast.
- Late:
When this option is selected, the
initial Forward Collision Warning is
activated later than normal. This
setting reduces the amount of dis-
tance between the vehicle, pedes-
trian or cyclist ahead before the ini-
tial warning occurs.
Select 'Late' when traffic is light
and when driving speed is slow.
When you accelerate suddenly to
the vehicle ahead, the warning
may seem to activate earlier even if
'Late' is selected.
Information
If you change the warning timing, the
warning timing of other systems may
change. Always be aware before
changing the warning timing.

Prerequisite for activation
FCA gets ready to be activated,
when 'Active Assist' or 'Warning
Only' under Forward Safety is select-
ed in the cluster LCD display, and
when the following prerequisites are
satisfied.
- ESC (Electronic Stability Control)
is on.
- Vehicle speed is over 5 mph (8
km/h). (The FCA is only activated
within a certain speed range.)
- The system detects a pedestrian,
cyclist (if equipped) or a vehicle in
front, which may collide with your
vehicle. However, FCA may not be
activated or may only sound a
warning alarm depending on the
driving or vehicle conditions.
The FCA may not operate properly
according to the frontal situation,
the direction of pedestrian or
cyclist (if equipped) and speed.
FCA warning message and
brake control
FCA produces warning messages,
warning alarms, and emergency
braking based on the level of risk of
a frontal collision, such as when a
vehicle ahead suddenly brakes, or
the system detects that a collision
with a pedestrian or cyclist (if
equipped) is imminent.To avoid driver distractions,
do not attempt to set or can-
cel FCA while driving the vehi-
cle. Always completely stop
the vehicle at a safe place
before setting or canceling
the system.
FCA automatically activates
when the POWER button is in
the ON position. The driver
can deactivate FCA by cancel-
ing the system setting on the
LCD display.
FCA automatically deactivates
upon canceling the ESC
(Electronic Stability Control).
When the ESC is canceled,
FCA cannot be activated on
the LCD display. In this situa-
tion, the FCA warning light will
illuminate which is normal.
