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 addition to inflating in certain side
collisions, vehicles equipped with a
rollover sensor, side impact air bags
and curtain air bags will inflate if the
sensing system detects a rollover.
When a rollover is detected, side
impact air bags and curtain air bags
will remain inflated longer to help pro-
vide protection from ejection, especial-
ly when used in conjunction with the
seat belts.
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.

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)
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 a side impact of
sufficient severity is detected.Although the driver’s and front passen-
ger’s air bags are designed to inflate only
in frontal collisions, they also may inflate
in other types of collisions if the front
impact sensors detect a sufficient
impact. Side impact air bags and curtain
air bags are designed to inflate only in
side impact collisions or rollover situa-
tions, but they may inflate in other colli-
sions 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.

What to do in an emergency
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the TPMS
to continue to function properly.
✽ ✽NOTICE
If any of the below happens, we rec-
ommend that the system be checked
by an authorized HYUNDAI dealer.
1.The low tire pressure telltale/
TPMS malfunction indicator does
not illuminate for 3 seconds when
the ignition switch is turned to the
ON or engine is running.
2. The TPMS malfunction indicator remains illuminated after blinking
for approximately 1 minute.
3. The Low tire pressure position telltale remains illuminated.
Low tire pressure
telltale
Low tire pressure
position telltale
When the tire pressure monitoring
system warning indicator is illuminat-
ed and warning message displayed
on the cluster LCD display, one or
more of your tires is significantly
under-inflated. The low tire pressure
position telltale light will indicate
which tire is significantly under-inflat-
ed by illuminating the corresponding
position light.
If either telltale illuminates, immediate-
ly reduce your speed, avoid hard cor-
nering and anticipate increased stop-
ping distances. You should stop and
check your tires as soon as possible. Inflate the tires to the proper pres-
sure as indicated on the vehicle’s
placard or tire inflation pressure label
located on the driver’s side center pil-
lar outer panel.
If you cannot reach a service station
or if the tire cannot hold the newly
added air, replace the low pressure
tire with the spare tire.
The Low Tire Pressure Telltale will
remain on and the TPMS Malfunction
Indicator may blink for one minute
and then remain illuminated (when
the vehicle is driven approximately
20 minutes at speed above 15.5 mph
(25 km/h)) until you have the low
pressure tire repaired and replaced
on the vehicle.
✽ ✽
NOTICE
The spare tire is not equipped with a
tire pressure sensor (if equipped
with a spare tire).
