Why Didn't My Air Bag Go Off
in a Collision?
Air bags are not designed to inflate in
every 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 colli-
sions in multiple impact accidents, as
well as low speed impacts. Damage
to the vehicle indicates a collision
energy absorption, and is not an indi-
cator of whether or not an air bag
should have inflated.
Air bag collision sensors
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 sen-
sors. 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.
Do not install bumper guards
or replace the bumper with a
non-genuine HYUNDAI parts.
This may adversely affect the
collision and air bag deploy-
ment performance.
(Continued)
(Continued)
Place the ignition switch in
the LOCK/OFF or ACC posi-
tion when the vehicle is being
towed to prevent inadvertent
air bag deployment.
Have all air bag repairs conduct-
ed by an authorized HYUNDAI
dealer.
WARNING

2-68
Safety system of your vehicle
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 colli-
sion energy is absorbed by the vehi-
cle structure.
SRS Care
The SRS is virtually maintenance-
free and there are no parts you can
safely service by yourself. If the SRS
air bag warning light does not illumi-
nate when the ignition switch or the
engine Start/Stop button is in the ON
position, or continuously remains on,
have your vehicle immediately
inspected by an authorized HYUNDAI
dealer.
Any work on the SRS system, such
as removing, installing, repairing, or
any work on the steering wheel, the
front passenger’s panel, front seats
and roof rails must be performed by
an authorized HYUNDAI dealer.
Improper handling of the SRS system
may result in serious personal injury. To reduce the risk of serious
injury or death, take the follow-
ing precautions:
Do not attempt to modify or
disconnect the SRS compo-
nents or wiring, including the
addition of any kind of badges
to the pad covers or modifica-
tions to the body structure.
Do not place objects over or
near the air bag modules on
the steering wheel, instrument
panel, or the front passen-
ger’s panel above the glove
box.
Clean the air bag pad covers
with a soft cloth moistened
with plain water. Solvents or
cleaners could adversely
affect the air bag covers and
proper deployment of the sys-
tem.
Always have inflated air bags
replaced by an authorized
HYUNDAI dealer.

Driving your vehicle
Anti-lock Brake System (ABS)
ABS is an electronic braking system
that helps prevent a braking skid.
ABS allows the driver to steer and
brake at the same time.
Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your
brake pressure and do not try to
pump your brakes. Depress your
brake pedal as hard as possible.
When you apply your brakes under
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This is
normal and it means your ABS is
active.
ABS does not reduce the time or dis-
tance it takes to stop the vehicle.
Always maintain a safe distance from
the vehicle in front of you.
ABS will not prevent a skid that
results from sudden changes in
direction, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather con-
ditions.
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 vehi-
cle 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-cov-
ered roads.
(Continued)
WARNING
(Continued)
On roads where the road sur-
face 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.
