Seat belt warning
(1) Driver’s seat belt warning light
(2) Front passenger’s seat belt warning
light
As a reminder to the driver and front pas-
senger, the driver’s and front passenger’s
seat belt warning lights will illuminate for
approximately 6 seconds each time you
turn the ignition switch ON regardless of
belt fastening.
If the driver’s or front passenger’s seat
belt is not fastened when the ignition
switch is turned ON or if it is disconnect-
ed after the ignition switch is turned ON,
the corresponding seat belt warning light
will illuminate until the belt is fastened.
(Continued)
Care should be taken to avoid con- tamination of the webbing with pol-
ishes, oils and chemicals, and par-
ticularly battery acid. Cleaning may
safely be carried out using mild
soap and water. The belt should bereplaced if webbing becomes
frayed, contaminated or damaged. It is essential to replace the entire
assembly after it has been worn in
a severe impact even if damage to
the assembly is not obvious. Belts
should not be worn with straps
twisted. Each belt assembly must
only be used by one occupant; it is
dangerous to put a belt around a
child being carried on the occu-pant's lap.
OYF039066R
WARNING
No modifications or additions should be made by the user
which will either prevent the seat
belt adjusting devices from oper-
ating to remove slack, or prevent
the seat belt assembly from being
adjusted to remove slack.
When you fasten the seat belt, be careful not to latch the seat belt in
buckles of other seat. It's very dan-
gerous and you may not be pro-
tected by the seat belt properly.
Do not unfasten the seat belt and do not fasten and unfasten the
seat belt repeatedly while driving.This could result in loss of con-
trol, and an accident causing
death, serious injury, or property
damage.
When fastening the seat belt, make sure that the seat belt does
not pass over objects that are
hard or can break easily.
Make sure there is nothing in the buckle. The seat belt may not be
fastened securely.

Driver's and passenger's front air
bag
Your vehicle is equipped with a
Supplemental Restraint (Air Bag) Systemand the lap/shoulder belts at both the
driver and passenger seating positions.The indications of the system's presence
are the letters "SRS AIR BAG" or "AIR
BAG" embossed on the air bag pad cover
in the steering wheel and the passen-
ger's side front panel pad above the
glove box. The SRS consists of air bags installed
under the pad covers in the centre of the
steering wheel and the passenger's side
front panel above the glove box.
WARNING
If an air bag deploys, there may be a loud noise followed by a fine
dust released in the vehicle.These conditions are normal and
are not hazardous - the air bags
are packed in this fine powder.
The dust generated during air
bag deployment may cause skin
or eye irritation as well as aggra-
vate asthma for some persons.
Always wash all exposed skin
areas thoroughly with lukewarmwater and a mild soap after an
accident in which the air bags
were deployed.
The SRS can function only when the ignition switch is in the ON
position. If the SRS " " warning
light does not illuminate, or con-
tinuously remains on after illumi-
nating for about 6 seconds when
the ignition switch is turned to
the ON position, or after the
engine is started, comes on
whilst driving, the SRS is not
working properly. If this occurs,
have your vehicle immediately
inspected by an authorised
HYUNDAI dealer.
(Continued)(Continued)
Before you replace a fuse or dis-connect a battery terminal, turn
the ignition switch to the LOCK
position and remove the ignition
key. Never remove or replace the
air bag related fuse(s) when the
ignition switch is in the ON posi-
tion. Failure to heed this warning
will cause the SRS “ ” warning
light to illuminate.
