CHECKING AND CHANGING THE EN- GINE COOLANT
WARNING: Do not remove the radiator cap when the
engine is hot. When the engine is hot, the engine coolant is under pressure and mayerupt through the opening if the cap isremoved. You could be seriously burned ifyou do not observe this precaution. Do notremove the radiator cap until the radiator iscool to the touch. G050B01A-AAT
Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant shouldbe compatible with aluminum engine parts.Additional corrosion inhibitors or additives shouldnot be used. The cooling system must be main-tained with the correct concentration and typeof engine coolant to prevent freezing and corro-sion. Never allow the concentration of anti-freeze to exceed the 60% level or go below the35% level, or damage to the cooling systemmay result. For proper concentration when add-ing or replacing the engine coolant, refer to thefollowing table.

G050C01A-AAT
To Check the Coolant Level The coolant level can be seen on the side of the plastic coolant reservoir. The level of the cool-ant should be between the "LOW" and "FULL"lines on the reservoir when the engine is cool.If the level is below the "LOW" mark, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect forcoolant leaks and recheck the fluid level fre-quently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason.
7. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-ter 9 for engine oil capacity.
8. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It is sug-gested that it be placed in a sealed containerand taken to a service station for maybereclaimation. Do not pour the oil on theground or put it in with the household trash.
WARNING: Used motor oil may cause irritation or can-
cer of the skin if left in contact with the skin for prolonged periods of time. Wash yourhands thoroughly with soap and warm wa-ter as soon as possible after handling usedoil.

Driver's Airbag
B240A01GK-GAT SUPPLEMENTAL RESTRAINT (AIRBAG) SYSTEM (SRS)(Not all models) Your Hyundai is equipped with a Supplemental Restraint (Airbag) System. The indications of thesystem's presence are the letters "SRS AIRBAG" embossed on the ornament in the steeringwheel and the passenger's side front panel padabove the glove box. The Hyundai SRS consists of airbags installed under the pad covers in the center of the steeringwheel and the passenger's side front panel abovethe glove box. The purpose of the SRS is toprovide the vehicle's driver and/or the front pas-senger with additional protection than that of-fered by the seat belt system alone, in case of afrontal impact of sufficient severity.
NOTE:
o Both the driver's and front passenger's
pre-tensioner seat belts will be activatedin certain frontal collisions. The pre-tensioner seat belts can be activated aloneor, where the frontal collision is severeenough, together with the airbags.
o When the pre-tensioner seat belts are ac- tivated, a loud noise may be heard and finedust, which may appear to be smoke, maybe visible in the passenger compartment.These are normal operating conditionsand are not hazardous.
o Although it is harmless, the fine dust may cause skin irritation and should not bebreathed for prolonged periods. Wash yourhands and face thoroughly after an acci-dent in which the pre-tensioner seat beltswere activated.
CAUTION:
o The control module that activates the SRS airbag controls the pre-tensioner seat beltalso.
o If there is some function in the pre- tensioner seat belt circuit, the warninglight will illuminate even if there is nomalfunction in the SRS airbag system. Ifthe SRS airbag warning light does notilluminate or illuminates continuouslywhen the ignition key is turned to "ON", orif it remains illuminated after blinking forapproximately 6 seconds, or if it illumi-nates while the vehicle is being driven, please have an authorized Hyundai dealerinspect the pre-tensioner seat belts and orSRS airbag system as soon as possible.
WARNING:
o Pre-tensioners are designed to operate only one time. After activation, pre-tensioner seat belts must be replaced. Allseat belts, of any type, should always bereplaced after they have been worn duringa collision.
o The pre-tensioner seat belt assembly mechanisms become hot during activa-tion. Do not touch the pre-tensioner seatbelt assemblies for several minutes afterthey 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 any manner.
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 inadvertent acti-vation and serious injury.
o Always wear seat belts when driving or riding in a motor vehicle.

CONTROLS AND EQUIPMENT1- 21
A fully inflated airbag in combination with a prop- erly worn seat belt slows the driver's or thepassenger's forward motion, thus reducing therisk of head and chest injury.After complete inflation, the airbag immediatelystarts deflating, enabling the driver to maintainforward visibility.
Passanger's Airbag
B240B01GK-D
CAUTION: Do not install or place any accessories (drinkholder, cassette holder, sticker, etc) on thefront passenger's panel above the glove boxin the vehicle with passenger's side air bag.Such objects may become dangerous pro-jectiles and cause injury if the passenger'sside air bag inflates. Upon deployment, tear seams molded directly into the pad covers will separate under pressurefrom the expansion of the airbags. Further open-ing of the covers then allows full inflation of theairbags.
The airbag modules are located both in thecentre of the steering wheel and in the frontpassenger's panel above the glove box. Whenthe SRSCM detects a considerable impact to thefront of the vehicle, it will automatically deploy theairbags.
B240B01GK-AAT SRS Components and Functions The SRS consists of the following components: - Driver's Side Airbag Module - Passenger's Side Airbag Module- SRS Service Reminder Indicator (SRI)- SRS Control Module (SRSCM) The SRSCM continually monitors all elements while the ignition is "ON" to determine if a frontalor near-frontal impact is severe enough to re-quire airbag deployment. The SRS service reminder indicator (SRI) on the instrument panel will blink for about 6 secondsafter the ignition key is turned to the "ON" positionor after the engine is started, after which the SRIshould go out.

CONTROLS AND EQUIPMENT1- 23
WARNING:
o Do not install a child restraint system in
the front passenger seat position.A child restraint system must never beplaced in the front seat. The infant or childcould be severely injured by an airbagdeployment in case of an accident.
o Extreme Hazard! Do not use a rearward facing child restraint on a seat protectedby an airbag in front of it!
o Modification to SRS components or wir-ing, including the addition of any kind of badgesto the pad cover or modifications to thebody structure, can adversely affect SRSperformance and lead to possible injury.
o For cleaning the horn pad, use only a soft, dry cloth or one which has been moist-ened with plain water. Solvents or clean-ers could adversely affect the airbag coverand proper deployment of the system.
o No objects should be placed over or near the airbag module on the steering wheel,because any such object could cause harmif the vehicle is in a crash severe enoughto cause the airbag to inflate.
o If the airbag inflates, it must be replaced by an authorized Hyundai dealer.
o Do not tamper with or disconnect SRS wiring, or other components of the SRSsystem. Doing so could result in injury,due to accidental firing of the airbag or byrendering the SRS inoperative.
o For best protection from the side airbag
system and to avoid being injured by thedeploying side airbag, both front seat oc-cupants should sit in an upright positionwith the seat belt properly fastened. Thedriver's hands should be placed on thesteering wheel at the 9:00 and 3:00 o'clockpositions. The passenger's arms andhands should be placed on their laps.
o Do not use any accessory seat covers.
o Use of seat covers could prevent or re- duce the effectiveness of the system.
o Do not install any accessories on the side or near the side airbag.
o Do not use excessive force on the side of the seat.
o Do not place any objects over the airbag or between the airbag and yourself.
o Do not place any objects (an umbrella, bag, etc.) between the front door and thefront seat. Such objects may become dan-gerous projectiles and cause injury if thesupplemental side air bag inflates.
o To prevent unexpected deployment of the side air bag that may result in personalinjury,avoid impact to the side airbag sen-sor when the ignition key is on. FB110C2-F SRS Care
YT10355A
The SRS is virtually maintenance-free and so there are no parts you can safely service byyourself. The entire SRS system must be in-spected by an authorized Hyundai dealer 10years after the date that the vehicle was manu-factured. Any work on the SRS system, such as removing, installing, repairing, or any work on the steeringwheel must be performed by a qualified Hyundaitechnician.Improper handling of the SRS system may resultin serious personal injury.
