About the Catalytic Converter
Exhaust gases passing through the catalytic
converter cause it to operate at very high tem- peratures. As a result, the introduction of largeamounts of unburned gasoline may cause it tooverheat and create a fire hazard. This can beavoided by observing the following:
o Use unleaded fuel only.
o Maintain your engine in good condition. Ex- tremely high converter temperatures can result from improper operation of the electri-cal, ignition or fuel injection systems.
o If your engine stalls, pings, knocks, or is hard to start, take your car to your Hyundaidealer as soon as possible and have thedifficulty corrected.
o Avoid driving with a very low fuel level. If your run out of gasoline, it could cause theengine to misfire and result in excessiveloading of the catalytic converter.
o Avoid idling the engine for periods longer than 10 minutes.
o Your Hyundai should not be either pushed or pulled to get it started. This can cause thecatalytic converter to overload.
o Take care not to stop your Hyundai over any combustible material such as grass, paper,leaves or rags. As these materials couldcome in contact with the catalytic converterand could cause a fire. o Do not touch the catalytic converter or any
other part of the exhaust system while theengine is running as it is very hot and couldresult in burns.
o Remember that your Hyundai dealer is your best source of assistance.

WARNING:
o Pre-tensioners are designed to operate only one time. After activation, pre-tensioner seat belts must be replaced.All seat belts, of any type, should al-ways be replaced after they have beenworn during a collision.
o The pre-tensioner seat belt assembly mechanisms become hot during activa-tion. Do not touch the pre-tensionerseat belt assemblies for several min-utes after they have been activated.
o Do not attempt to inspect or replace the pre-tensioner seat belts yourself. Thismust be done by an authorized Hyundaidealer.
o Do not strike the pre-tensioner seat belt assemblies.
o Do not attempt to service or repair the pre-tensioner seat belt system in anymanner.
o Improper handling of the pre-tensioner seat belt assemblies, and failure to heedthe warnings to not strike, modify, in-spect, replace, service or repair the pre-tensioner seat belt assemblies may leadto improper operation or inadvertentactivation and serious injury.

o When the pre-tensioner seat belts are activated, a loud noise may be heardand fine dust, which may appear to besmoke, may be visible in the passengercompartment. These are normal operat-ing conditions and are not hazardous.
o Although it is harmless, the fine dust may cause skin irritation and shouldnot be breathed for prolonged periods.Wash your hands and face thoroughlyafter an accident in which the pre-tensioner seat belts were activated.
CAUTION:
o Because the sensor that activates the SRS airbag is connected with the pre- tensioner seat belt, the SRS airbag warn-ing light on the instrument panel willblink for approximately 6 seconds afterthe ignition key has been turned to the
"ON" position and then it should turn off.
o If the pre-tensioner seat belt is not work- ing properly, this warning light will illu-minate even if there is no malfunctionof the SRS airbag system. If the SRS airbag warning light does not illuminate when the ignition key is turnedto "ON", or if it remains illuminatedafter blinking for approximately 6 sec-onds, or if it illuminates while the ve-hicle is being driven, please have anauthorized Hyundai dealer inspect the
