Curtain air bags (if equipped)
Curtain air bags are located along
both sides of the roof rails above the
front and rear doors.They are designed to help protect the
heads of the front seat occupants
and the rear outboard seat occupants
in certain side impact collisions.
The curtain air bags are designed to
deploy during certain side impact
collisions, depending on the crash
severity, angle, speed and impact.
The curtain air bags are not designed
to deploy in all side impact situations. (Continued)
•Do not install any accessories
on the side or near the side air
bags.
•Do not put any objects
between the side air bag label
and seat cushion. It could
cause harm if the vehicle is in
a crash severe enough to
cause the air bags to deploy.
•Do not cause impact to the
doors when the ignition switch
is in the ON position or this
may cause the side air bags to
inflate.
•If the seat or seat cover is
damaged, we recommend that
the system be serviced by an
authorized HYUNDAI dealer.

To reduce the risk of serious
injury or death from an inflating
curtain air bag, take the follow-
ing precautions:
•All seat occupants must wear
seat belts at all times to help
keep occupants positioned
properly.
•Properly secure Child Restraint
System as far away from the
door as possible.

WARNING

2-70
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 is in the
ON position, or continuously remains
on, we recommend that the system
be immediately inspected by an
authorized HYUNDAI dealer.
We recommend 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 be performed
by an authorized HYUNDAI dealer.
Improper handling of the SRS system
may result in serious personal injury.
OAE036056
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, and the front passenger'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 system.
•We recommend that inflated
air bags be replaced by an
authorized HYUNDAI dealer.

If you suspect your smart key might
have sustained some damage, or
you feel your smart key is not work-
ing correctly, it is recommended that
you contact an authorized HYUNDAI
dealer.
Information
An inappropriately disposed
battery can be harmful to the
environment and human
health. Dispose of the battery
according to your local law(s)
or regulations.
Immobilizer system
(if equipped)
The immobilizer system protects your
vehicle from theft. If an improperly
coded key (or other device) is used,
the engine’s fuel system is disabled.
When the ignition switch is placed in
the ON position, the immobilizer sys-
tem indicator should come on briefly,
then go off. If the indicator starts to
blink, the system does not recognize
the coding of the key.
Place the ignition switch to the
LOCK/OFF position, then place the
ignition switch to the ON position
again.
The system may not recognize your
key’s coding if another immobilizer
key or other metal object (i.e., key
chain) is near the key. The engine
may not start because the metal may
interrupt the transponder signal from
transmitting normally.
If the system repeatedly does not
recognize the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.Do not attempt to alter this system or
add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.
The transponder in your key is an
important part of the immobilizer
system. It is designed to give
years of trouble-free service, how-
ever you should avoid exposure to
moisture, static electricity and
rough handling. Immobilizer sys-
tem malfunction could occur.
NOTICE
iIn order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
immobilizer password is a cus-
tomer unique password and
should be kept confidential.
WARNING

Convenient features of your vehicle
Avoid driving with an extremely
low fuel level. Running out of fuel
could cause the engine to misfire
damaging the catalytic converter.
Hybrid battery SOC
(State of Charge) gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the "0 or L (Low)" level, the
vehicle automatically operates the
engine to charge the battery.However, if the Service Indicator
( ) and Malfunction Indicator
Lamp (MIL) ( ) turn on when the
SOC gauge is near the "0 or L (Low)"
level, we recommend the vehicle be
checked by an authorized HYUNDAI
dealer.
Never try to start the vehicle if the
fuel tank is empty. In this condi-
tion, the engine cannot charge the
high voltage battery of the hybrid
system. If you try to start the vehi-
cle when the fuel is empty, the
high voltage battery will become
discharged and be damaged.
NOTICE
NOTICE
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addi-
tional fuel as soon as possible
after the warning light comes
on or when the gauge indicator
comes close to the "0 or E
(Empty)" level.
