Do not install a Child Restraint
System on the Front Passenger’s
Seat
OHI039193N
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger’s seat.
An inflating air bag can forcefully strike a
child or child restraint resulting in serious
or fatal injury.
WARNING
NEVER use a rearward facing Child
Restraint on a seat protected by an
ACTIVE AIRBAG in front of it, DEATH
or SERIOUS INJURY to the CHILD can
occur.
Why didn’t my air bag go off in a
collision?
There are certain types of accidents in
which the air bag would not be expected
to provide additional protection. These
include rear impacts, second or third
collisions in multiple impact accidents,
as well as low speed impacts. Damage to
the vehicle indicates a collision energy
absorption, and is not an indicator of
whether or not an air bag should have
inflated.
Air bag collision sensors
WARNING
To reduce the risk of an air bag
deploying unexpectedly and causing
serious injury or death:
• Do not hit or allow any objects to
impact the locations where air bags
or sensors are installed.
• Do not perform maintenance on or
around the air bag sensors. If the
location or angle of the sensors is
altered, the air bags may deploy
when they should not or may not
deploy when they should.
• Installing bumper guards with non-
genuine Hyundai or non-equivalent
parts may adversely affect the
collision and airbag deployment
performance.
• Press the Engine Start/Stop button to
the OFF or ACC position and wait for
3 minutes when the vehicle is being
towed to prevent inadvertent air bag
deployment.
• We recommend that all air bag
repairs are conducted by an
authorized HYUNDAI dealer.

Air bag inflation conditions
ONX4030046
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on the
severity of impact of the front collision.
ONX4030050
OTM030033
Side and curtain air bags
Side and curtain air bags are designed
to inflate when an impact is detected
by side collision sensors depending on
the severity, speed or angles of impact
resulting from a side impact collision.
Although the driver’s and front
passenger’s air bags are designed to
inflate in frontal collisions, they also may
inflate in other types of collisions if the
front impact sensors detect a sufficient
impact. Side and curtain air bags are
designed to inflate in side impact
collisions, but they may inflate in other
collisions if the side impact sensors
detect a sufficient impact.
Also, the side and curtain air bags are
designed to inflate when a rollover
is detected by a rollover sensor. (if
equipped with rollover sensor)
If the vehicle chassis is impacted by
bumps or objects on unimproved roads,
the air bags may deploy. Drive carefully
on unimproved roads or on surfaces not
designed for vehicle traffic to prevent
unintended air bag deployment.

Air bag non-inflation conditions
ONX4030047
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.
ONX4030048
Front 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 provide any additional benefit.
ONX4030049
Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide additional
occupant protection.
However, side and curtain air bags
and front center air bag may inflate
depending on the severity of impact.
OTM030034
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 benefit, and thus
the sensors may not deploy any air bags.

03
3-65
ONX4030051
Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it
to “ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this “underride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.
ONX4030053
Front air bags may not inflate in
rollover accidents because front air bag
deployment would not provide additional
occupant protection.
However, the side and curtain air bags
and front center air bag may inflate in a
rollover situation, when it is detected by
the rollover sensor.
ONX4030052
Air bags may not inflate if the vehicle
collides with objects such as utility poles
or trees, where the point of impact is
concentrated and the collision energy is
absorbed by the vehicle structure.

Note that if you press the outside door
handle to lock the doors using the touch
sensor, the doors will not lock under the
following circumstances:
• The Smart Key is in the vehicle
• The Engine Start/Stop button is in the
ACC or ON position
• Any of the doors are open (except for
the liftgate)
If this occurs, then a chime will sound
for about 3 seconds. Check the vehicle
before attempting to lock the car again.
CAUTION
Before you leave your vehicle with the
Smart Key, verify that your vehicle is
locked. When using the touch sensor
on the front door handle, listen to hear
that the lock has actuated, and then
pull the handle within 3 seconds to
confirm the doors are locked.
(if it has been longer than 3 seconds,
verify the doors are locked by pressing
the lock button on the Smart Key. You
will hear a single beep.)
WARNING
Do not leave the Smart Key in
your vehicle with children that are
unattended or unsupervised.
Children could inadvertently press
the Engine Start/Stop button or could
operate the power windows or other
vehicle controls or even cause the
vehicle to move. This could result in
serious injury or death.
