Airbag collision sensors  
Why didn’t my airbag go off in  
a collision?  
There are certain types of accidents in  
which the airbag 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 ener-  
gy absorption, and is not an indicator of  
whether or not an airbag should have  
inflated.  
WARNING  
To reduce the risk of an airbag  
deploying unexpectedly and caus-  
ing 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 airbag sensors. If the  
location or angle of the sensors is  
altered, the airbags 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.  
To ensure correct function of the  
airbag system, we recommend to  
replace the bumper with genuine  
HYUNDAI part or the equivalent (of  
the genuine part) specified for  
your vehicle.  
• Place the ignition switch to the  
LOCK/OFF or ACC position, when  
the vehicle is being towed to pre-  
vent inadvertent airbag deploy-  
ment.  
• We recommend that all airbag  
repairs are performed by a HYUN-  
DAI authorised repairer.

Airbag inflation conditions  
OAC3039028R  
OAC3039027TU  
Front airbags  
Front airbags are designed to inflate in  
a frontal collision depending on the  
severity of impact of the front collision.  
OAC3039029R  
Side and curtain airbags  
Side and curtain airbags are designed  
to inflate when an impact is detected by  
side collision sensors depending on the  
severity of impact resulting from a side  
impact collision. Although the driver’s  
and front passenger’s airbags are  
designed to inflate only in frontal colli-  
sions, they also may inflate in other  
types of collisions if the front impact  
sensors detect a sufficient impact. Side  
and curtain airbags are designed to  
inflate only in side impact collisions or  
rollover situations (if equipped with roll-  
over sensor), but they may inflate in  
other collisions if the side impact sen-  
sors detect a sufficient impact. If the  
vehicle chassis is impacted by bumps or  
objects on unimproved roads, the airbags  
may deploy. Drive carefully on unim-  
proved roads or on surfaces not designed  
for vehicle traffic to prevent unintended  
airbag deployment.

Airbag non-inflation conditions  
OAC3033028R  
OAC3039030TU  
Front airbags may not inflate in side  
impact collisions, because occupants  
move in the direction of the collision,  
and thus in side impacts, front airbag  
deployment would not provide addition-  
al occupant protection.  
In certain low-speed collisions the air-  
bags may not deploy. The airbags are  
designed not to deploy in such cases  
because they may not provide benefits  
beyond the protection of the seat belts.  
However, side and curtain airbags may  
inflate depending on the severity of  
impact.  
OAC3039031TU  
Front airbags are not designed to inflate  
in rear collisions, because occupants  
are moved backward by the force of the  
impact. In this case, inflated airbags  
would not provide any additional bene-  
fit.  
OBH038060  
In an angled collision, the force of  
impact may direct the occupants in a  
direction where the airbags would not  
be able to provide any additional bene-  
fit, and thus the sensors may not deploy  
any airbags.

Information  
i
Vehicles equipped with rollover sen-  
sor  
The side and curtain airbags may  
inflate in a rollover situation, when it  
is detected by the rollover sensor.  
Vehicles not equipped with rollover  
sensor  
OAC3039033TU  
The side and/or curtain airbags may  
inflate when the vehicle is rolled over  
by a side impact collision, if the vehi-  
cle is equipped with side and/or cur-  
tain airbags.  
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. Airbags may not  
inflate in this “under-ride” situation  
because deceleration forces that are  
detected by sensors may be significant-  
ly reduced by such “underride” colli-  
sions.  
OAC3033034TU  
Airbags 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.  
OHI038166  
Front airbags may not inflate in rollover  
accidents because front airbag deploy-  
ment would not provide additional  
occupant protection.
