Door Ajar Warning Light
The door ajar warning light warns you that a dooris not completely closed.
B260H01GK-AAT Parking Brake/Low Brake Fluid Level Warning Light
CAUTION: If you suspect brake trouble, have your brakeschecked by a Hyundai dealer as soon aspossible. Driving your car with a problem ineither the brake electrical system or brakehydraulic system is dangerous, and couldresult in a serious injury or death. Warning Light Operation The parking brake/brake fluid level warning light should come on when the parking brake is ap-plied and the ignition switch is turned to "ON" or"START". After the engine is started, the lightshould go out in three seconds.If the parking brake is not applied, the warninglight should come on when the ignition switch isturned to "ON" or "START", then go out in threeseconds. If the light comes on at any other time,you should slow the vehicle and bring it to acomplete stop in a safe location off the roadway.The brake fluid level warning light indicates thatthe brake fluid level in the brake master cylinderis low and hydraulic brake fluid conforming toDOT 3 or DOT 4 specifications should be added.After adding fluid, if no other trouble is found, thecar should be immediately and carefully driven toa Hyundai dealer for inspection. If further troubleis experienced, the vehicle should not be drivenat all but taken to a dealer by a professionaltowing service or some other safe method. Your Hyundai is equipped with dual-diagonalbraking systems. This means you still have brak-ing on two wheels even if one of the dual systemsshould fail. With only one of the dual systemsworking, more than normal pedal travel andgreater pedal pressure are required to stop thecar. Also, the car will not stop in as short adistance with only half of the brake system work-ing. If the brakes fail while you are driving, shift toa lower gear for additional engine braking andstop the car as soon as it is safe to do so.
B260M01A-AAT
Low Fuel Level Warning Light
The low fuel level warning light comes on when the fuel tank is approaching empty. When itcomes on, you should add fuel as soon aspossible. Driving with the fuel level warning lighton or with the fuel level below "E" can cause theengine to misfire and damage the catalytic con-verter.

off your engine and restart only when you're ready to go.
o Remember, your Hyundai does not require extended warm-up. As soon as the engine isrunning smoothly, you can drive away. Invery cold weather, however, give your enginea slightly longer warm-up period.
o Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too high a gear result-ing in the engine bucking. If this happens, shiftto a lower gear. Over-revving is racing theengine beyond its safe limit. This can beavoided by shifting at the recommendedspeeds.
o Use your air conditioning sparingly. The air conditioning system is operated by enginepower so your fuel economy is reduced whenyou use it.
crease wear on these components. In addi-tion, driving with your foot resting on the brakepedal may cause the brakes to overheat,which reduces their effectiveness and maylead to more serious consequences.
o Take care of your tires. Keep them inflated to the recommended pressure. Incorrect infla-tion, either too much or too little, results inunnecessary tire wear. Check the tire pres-sures at least once a month.
o Be sure that the wheels are aligned correctly. Improper alignment can result from hittingcurbs or driving too fast over irregular surfac-es. Poor alignment causes faster tire wearand may also result in other problems as wellas greater fuel consumption.
o Keep your car in good condition. For better fuel economy and reduced maintenancecosts, maintain your car in accordance withthe maintenance schedule in Section 5. If youdrive your car in severe conditions, morefrequent maintenance is required (see Sec-tion 5 for details).
o Keep your car clean. For maximum service, your Hyundai should be kept clean and free ofcorrosive materials. It is especially importantthat mud, dirt, ice, etc. not be allowed toaccumulate on the underside of the car. Thisextra weight can result in increased fuel con-sumption and also contribute to corrosion.
o Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel economy.
o Don't let the engine idle longer than neces- sary. If you are waiting (and not in traffic), turn C150A01A-AAT
SMOOTH CORNERING
Avoid braking or gear changing in corners, espe-cially when roads are wet. Ideally, corners shouldalways be taken under gentle acceleration. If youfollow these suggestions, tire wear will be held toa minimum. C160A01A-AAT WINTER DRIVING The more severe weather conditions of winter result in greater wear and other problems. Tominimize the problems of winter driving, youshould follow these suggestions:
If the indicator remains lit even after the enginehas been started, have your car checked by anauthorized Hyundai dealer. NOTE:
1) When the TCS-OFF indicator illuminates,
traction control is automatically deacti-vated for safety.
2) This warning function is not provided when the driver selects the TCS-OFF mode.
C140A01A-GAT DRIVING FOR ECONOMY You can save fuel and get more kilometers from your car if you follow these suggestions:
o Drive smoothly. Accelerate at a moderate rate. Don't make "jack-rabbit" starts or full- throttle shifts and maintain a steady cruisingspeed. Don't race between stoplights. Try toadjust your speed to that of the other traffic soyou don't have to change speeds unneces-sarily. Avoid heavy traffic whenever possible.Always maintain a safe distance from othervehicles so you can avoid unnecessary brak-ing. This also reduces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel your car uses. Driving ata moderate speed, especially on the high-way, is one of the most effective ways toreduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This can increase fuel consumption and also in-

C170A01A-AAT HIGHER SPEED MOTORING Pre-Trip Inspections 1. Tires: Adjust the tire inflation pressures to specifica-tion. Low tire inflation pressures will result inoverheating and possible failure of the tires.Avoid using worn or damaged tires which mayresult in reduced traction or tire failure. NOTE: Never exceed the maximum tire inflation pres-sure shown on the tires. 2. Fuel, engine coolant and engine oil: High speed travel consumes more fuel thanurban motoring. Do not forget to check bothengine coolant and engine oil. 3. Drive belt: A loose or damaged drive belt may result inoverheating of the engine. C180A01A-AAT USE OF LIGHTS Check your lights regularly for correct operation and always keep them clean. When driving dur-ing the day in conditions of poor visibility, it ishelpful to drive with headlights on low beam. Thisenables you to be seen as well as to see.
C160I01A-AAT Don't Let Your Parking Brake FreezeUnder some conditions your parking brake can freeze in the engaged position. This is most likelyto happen when there is an accumulation of snowor ice around or near the rear brakes or if thebrakes are wet. If there is a risk the parking brakemay freeze, apply it only temporarily while youput the gear selector lever in "P" (automatic) or infirst or reverse gear (manual transaxle) andblock the rear wheels so the car cannot roll. Thenrelease the parking brake. C160K01A-AAT Carry Emergency Equipment Depending on the severity of the weather where you drive your car, you should carry appropriateemergency equipment. Some of the items youmay want to carry include tire chains, tow strapsor chains, flashlight, emergency flares, sand, ashovel, jumper cables, a window scraper, gloves,ground cloth, coveralls, a blanket, etc.
C160J01A-AAT Don't Let Ice and Snow Accumulate Underneath Under some conditions, snow and ice can build up under the fenders and interfere with the steer-ing. When driving in severe winter conditionswhere this may happen, you should periodicallycheck underneath the car to be sure the move-ment of the front wheels and the steering compo-nents is not obstructed.
C190B01S-AAT Trailer Hitches Select the proper hitch and ball combination, making sure that it's location is compatible withthat of the trailer or vehicle being towed.Use a quality non-equalizing hitch which distrib-utes the tongue load uniformly throughout thechassis. The hitch should be bolted securely to the car and installed by a qualified technician. DO NOTUSE A HITCH DESIGNED FOR TEMPORARYINSTALLATION AND NEVER USE ONE THATATTACHES ONLY TO THE BUMPER.
C190A01A-GAT TRAILER OR VEHICLE TOWINGIf you are considering towing with your car, you should first check with your Province Depart-ment of Motor Vehicles to determine their legalrequirements.Since laws vary from province to province, therequirements for towing trailers, cars, other typesof vehicles, or apparatus may differ. Ask yourHyundai dealer for further details before towing. CAUTION Do not do any towing with your car during itsfirst 2,000 km (1,200 miles) in order to allowthe engine to properly break in. Failure toheed this caution may result in serious en-gine or transaxle damage.

C190F01A-GAT Trailer or Vehicle Towing Tips
1. Before towing, check hitch and safety chainconnections as well as proper operation of the trailer running lights, brake lights, and turnsignals.
2. Always drive your vehicle at a moderate speed (Less than 100 km/H).
3. Trailer towing requires more fuel than normal conditions.
4. To maintain engine braking efficiency and electrical charging performance, do not usefifth gear (manual transaxle) or overdrive(automatic transaxle).
5. Always secure items in the trailer to prevent load shift while driving.
6. Check the condition and air pressure of all tires on the trailer and your car. Low tirepressure can seriously affect the handling.Also check the spare tire.
7. The vehicle/trailer combination is more af- fected by crosswind and buffeting.When being passed by a large vehicle, keepa constant speed and steer straight ahead. Ifthere is too much wind buffeting, slow down toget out of the other vehicle's air turbulence.
8. When parking your car and trailer, especially on a hill, be sure to follow all the normalprecautions. Turn your front wheel into thecurb, set the parking brake firmly, and put thetransmission in 1st or Reverse (manual) orPark (automatic). In addition, place wheelchocks at each of the trailer's tires.

To Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenance schedule in Section 5.
NOTE: Engine coolant can damage the finish of
your car. If you spill engine coolant on the car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park- ing brake and remove the radiator cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the engine coolant to drain from thecooling system, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer's directions on the enginecoolant container, add the appropriate quan-tity of engine coolant to the radiator.
4. Turn the radiator cap counterclockwise with- out pressing down on it, until it stops. Thisrelieves any pressure remaining in the cool-ing system. And remove the radiator cap bypushing down and turning counterclockwise. Now fill the radiator with clean demineral- ized or distilled water. Continue to add cleandemineralized or distilled water in small quan-tities until the fluid level stays up in theradiator neck. DOHC1.0~1.1 mm (0.039 ~ 0.043 in.)
