How does the air bag system
operate
Air bags are activated (able to inflate ifnecessary) only when the ignition
switch is turned to the ON or START
position.
Air bags inflate instantly in the event of serious frontal or side collision in order
to help protect the occupants from seri-
ous physical injury.
There is no single speed at which the air bags will inflate.
Generally, air bags are designed to
inflate by the severity of a collision and
its direction. These two factors deter-
mine whether the sensors send out an
electronic deployment/ inflation signal.
Air bag deployment depends on a number of factors including vehicle
speed, angles of impact and the densi-
ty and stiffness of the vehicles or
objects which your vehicle hits in the
collision. Though, factors are not limit-
ed to those mentioned above.
The front air bags will completely inflate and deflate in an instant.
It is virtually impossible for you to see
the air bags inflate during an accident. It is much more likely that you will sim-
ply see the deflated air bags hanging
out of their storage compartments after
the collision.
In order to help provide protection in a severe collision, the air bags must
inflate rapidly. The speed of air bag
inflation is a consequence of the
extremely short time in which a collision
occurs and the need to get the air bag
between the occupant and the vehicle
structures before the occupant impacts
those structures. This speed of inflation
reduces the risk of serious or life-
threatening injuries in a severe collision
and is thus a necessary part of air bag
design.
However, air bag inflation can also
cause injuries which normally can
include facial abrasions, bruises and
broken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
There are even circumstances under which contact with the air bag
can cause fatal injuries, especially if
the occupant is positioned exces-
sively close to the air bag.
WARNING
To avoid severe personal injuryor death caused by deploying air
bags in a collision, the driver
should sit as far back from the
steering wheel air bag as possi-
ble (at least 10 inches (250 mm)
away). The front passengers
should always move their seats
as far back as possible and sit
back in their seat.
Air bags inflate instantly in the event of collision, and passen-
gers may be injured by the air bag
expansion force if they are not in
proper position.
Air bag inflation may cause injuries which normally include
facial or bodily abrasions,
injuries from broken glasses or
burns by the air bag inflation
gasses.

Why didn’t my air bag go off in a
collision? (Inflation and non-infla-
tion conditions of the air bag)
There are many types of accidents in
which the air bag would not be expect-
ed to provide additional protection.
These include rear impacts, second or
third collisions in multiple impact
accidents, as well as low speed
impacts. In other words, just because
your vehicle is damaged and even if it
is totally unusable, don’t be surprised
that the air bags did not inflate.

Air bag inflation conditions
Front air bags
Front air bags are designed to inflate in a
frontal collision depending on the intensi-
ty, speed or angles of impact of the front
collision.
WARNING
Do not hit or allow any objects to
impact the locations where air
bags or sensors are installed.
This may cause unexpected air
bag deployment, which could
result in serious personal injury
or death.
If the installation location or angle of the sensors is altered in
any way, the air bags may deploy
when they should not or they may
not deploy when they should,
causing severe injury or death.
Therefore, do not try to perform
maintenance on or around the air
bag sensors. Have the vehicle
checked and repaired by an
authorized HYUNDAI dealer.
(Continued)
(Continued)
Problems may arise if the sensorinstallation angles are changed
due to the deformation of the
front bumper, body or B pillars or
front door where side collision
sensors are installed. Have the
vehicle checked and repaired by
an authorized HYUNDAI dealer.
Your vehicle has been designed to absorb impact and deploy the
air bag(s) in certain collisions.
Installing bumper guards or
replacing a bumper with non-gen-
uine parts may adversely affect
your vehicle’s collision and air
bag deployment performance.

Side impact and curtain air bags
(if equipped)
Side impact and curtain air bags are
designed to inflate when an impact is
detected by side collision sensors
depending on the strength, speed or
angles of impact resulting from a side
impact collision.Although the front air bags (driver’s and
front passenger’s air bags) are designed
to inflate only in frontal collisions, they
also may inflate in other types of colli-
sions if the front impact sensors detect a
sufficient impact. Side impact and curtain
air bags are designed to inflate only in
side impact collisions, but they may
inflate in other collisions if the side
impact sensors detect a sufficient
impact.
If the vehicle chassis is impacted by
bumps or objects on unpaved roads, the
air bags may deploy. Drive carefully on
unpaved roads or on surfaces not
designed for vehicle traffic to prevent
unintended air bag deployment.
Air bag non-inflation conditions
In certain low-speed collisions the air
bags may not deploy. The air bags are
designed not to deploy in such cases
because they may not provide benefits
beyond the protection of the seat belts
in such collisions.

Air bags are not designed to inflate in
rear collisions, because occupants are
moved backward by the force of the
impact. In this case, inflated air bags
would not be able to provide any addi-
tional benefit. Front air bags may not inflate in side
impact collisions, because occupants
move to the direction of the collision,
and thus in side impacts, frontal air bag
deployment would not provide addi-
tional occupant protection.
However, side impact and curtain air
bags may inflate depending on the
intensity, vehicle speed and angles of
impact. In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would not
be able to provide any additional bene-
fit, and thus the sensors may not
deploy any air bags.

Impact sensing door unlock system
(if equipped)
All doors will be automatically unlocked
when the impact is delivered to impact
sensors while the ignition switch is ON.
However, the doors may not be unlocked
if mechanical problems occur with the
door lock system or battery.
Speed sensing door lock system
(if equipped)
All doors will be automatically locked
after the vehicle speed exceeds 9 mph
(15 km/h). And all doors will be automat-
ically unlocked when you turn the engine
off or when you remove the ignition key.
(if equipped)
WARNING- Unattended
children
An enclosed vehicle can become
extremely hot, causing death or
severe injury to unattended chil-
dren or animals who cannot escape
the vehicle. Furthermore, children
might operate features of the vehi-
cle that could injure them, or they
could encounter other harm, possi-
bly from someone gaining entry to
the vehicle. Never leave children or
animals unattended in your vehicle.

Automatic heating and air condi-
tioning
The automatic climate control system is
controlled by simply setting the desired
temperature.
The Full Automatic Temperature Control
(FATC) system automatically controls the
heating and cooling system as follows;
1. Push the AUTO button. The modes,fan speeds, air intake and air-condi-
tioning will be controlled automatically
by temperature setting. 2. Turn the temperature control knob to
set the desired temperature.
If the temperature is set to the lowest
setting (LO), the air conditioning sys-
tem will operate continuously.
3. To turn the automatic operation off, press any button except the tempera-
ture control knob. If you press the
mode selection button, air conditioning
button, defrost button, air intake con-
trol button, or the fan speed knob, the
selected function will be controlled
manually while other functions operate
automatically.
For your convenience and to improve the
effectiveness of the climate control, use
the AUTO button and set the temperature
to 73°F (23°C).
✽ ✽ NOTICE
Never place anything over the sensor
located on the instrument panel to
ensure better control of the heating and
cooling system.
