WARNING
To reduce the risk of serious injury or
death from an inflating side air bag,
take the following precautions:
• Seat belts must be worn at all times
to help keep occupants positioned
properly.
• Do not allow passengers to lean their
heads or bodies onto doors, put their
arms on the doors, stretch their arms
out of the window, or place objects
between the doors and seats.
• Hold the steering wheel at the 9
o’clock and 3 o’clock positions, to
minimize the risk of injuries to your
hands and arms.
• Do not use any accessory seat
covers. This could reduce or prevent
the effectiveness of the system.
• Do not place any objects over the
air bag or between the air bag and
yourself. Also, do not attach any
objects around the area the air bag
inflates such as the door, side door
glass, front and rear pillar.
• Do not place any objects between
the door and the seat. They may
become dangerous projectiles if the
side air bag inflates.
• Do not install any accessories on the
side or near the side air bags.
• Do not put any objects between the
side airbag label and seat cushion. It
could cause harm if the vehicle is in a
crash severe enough to cause the air
bags to deploy.
• Do not cause impact to the doors
when the ignition switch button is in
the ON position as this may cause the
side air bags to inflate.
• If the seat or seat cover is damaged,
have the vehicle checked and
repaired by an authorized HYUNDAI
dealer.
Curtain air bags
ODN8039042ODN8039042
ODN8039043ODN8039043
Curtain air bags are located along both
sides of the roof rails above the front and
rear doors.
They are designed to help protect the
heads of the front seat occupants and
the rear outboard seat occupants in
certain side impact collisions.
The curtain air bags are designed to
deploy during certain side impact
collisions, depending on the crash
severity.
The side and curtain air bags on both
sides of the vehicle may deploy if a
rollover or possible rollover is detected.
The curtain air bags are not designed
to deploy in all side impact or rollover
situations.

When the SRSCM detects a sufficiently
severe impact to the front of the vehicle,
it will automatically deploy the front air
bags.

Upon deployment, tear seams molded
directly into the pad covers will separate
under pressure from the expansion of the
air bags. Further opening of the covers
allows full inflation of the air bags.
A fully inflated air bag, in combination
with a properly worn seat belt, slows the
driver or the front passenger forward
motion, reducing the risk of head and
chest injury.

After complete inflation, the air bag
immediately starts deflating, enabling
the driver to maintain forward visibility
and the ability to steer or operate other
controls.
WARNING
To prevent objects from becoming
dangerous projectiles when the
passenger’s air bag inflates:
• Do not install or place any objects
(drink holder, CD holder, stickers,
etc.) on the front passenger’s panel
above the glove box where the
passenger’s air bag is located.
• Do not install a container of liquid
air freshener near the instrument
cluster or on the instrument panel
surface.

visibility (smog, smoke, dust, fog,
heavy rain, snow, etc.).
• When the windshield visibility is
poor. WARNING
• Do not attempt to disassemble
the front view camera without the
assistance of an authorized HYUNDAI
dealer technician. If the front camera
is removed for any reason, the

Anti-lock Brake System (ABS)
WARNING
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 vehicle
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-covered
roads.
• On roads where the road surface 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.
ABS is an electronic braking system that
helps prevent a braking skid. ABS allows
the driver to steer and brake at the same
time.

ESC OFF usage
When Driving
The ESC OFF mode should only be used
brie
fly to help free the vehicle if stuck in
snow 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
To prevent damage to the transmission:
• 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 covered by the vehicle warranty.
Reduce engine power and do not
spin the wheel(s) excessively while
these lights are displayed.
• 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 operation.
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 suddenly on wet, slippery and
rough roads where traction over the four
tires can suddenly become uneven.
WARNING
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 substitute for safe
driving practices.
• Never drive too fast for the road
conditions. The VSM system will not
prevent accidents. Excessive speed
in bad weather, slippery and uneven
roads can result in severe accidents.
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 ma
y activate the ESC,
you may hear sounds from the brakes,
or feel a corresponding sensation in the
brake pedal. This is normal 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.
