!WARNING:
o Avoid high cornering speeds.
o Do not make quick steering wheel movements, such as sharp lanechanges or fast, sharp turns.
o Exercise extreme caution when driv-
ing on a slippery surface. Be espe-cially careful when braking, acceler- ating or shifting gears. On a slippery surface, an abrupt change in ve-hicle speed can cause the drive wheels to lose traction and the ve- hicle to go out of control.
o Optimum vehicle performance and economy is obtained by smoothlydepressing and releasing the accel-erator pedal.
o Turn the overdrive switch on for good
fuel economy and smooth driving. Ifengine braking is needed in the "D" range or if repeated upshifting and downshifting between 3rd and 4thgear is needed when climbing a gentle slope, it is recommended that the overdrive switch be turned off. Turnthe overdrive switch back on imme- diately afterward.
C090N05A-AAT Good Driving Practices
o Never move the gear selector lever
from "P" or "N" to any other position with the accelerator pedal de- pressed.
o Never move the gear selector lever into "P" when the vehicle is in mo-tion.
o Be sure the car is completely stopped before you attempt to shift into "R".
o Never take the car out of gear and
coast down a hill. This may be ex- tremely hazardous. Always leave the car in gear when moving.
o Do not "ride" the brakes. This can cause them to overheat and mal-function. Instead, when you are driv- ing down a long hill, slow down andshift to a lower gear. When you do this, engine braking will help slow the car.
o Slow down before shifting to a lower gear. Otherwise, the lower gear maynot be engaged.
o Always use the parking brake. Do not depend on placing the transaxlein "P" to keep the car from moving. o Always wear your seat belts.
In a collision crash, an unbeltedperson is significantly more likelyto die than a person wearing a seatbelt.
o The risk of rollover is greatly in- creased if you lose control ofyour vehicle at highway speeds.
o Loss of control often occurs if two or more wheels drop off theroadway and the driver oversteers to reenter the roadway.
o In the event your vehicle leaves the roadway, do not steer sharply.Instead, slow down before pull- ing back into the travel lanes.
o Never exceed posted speed limits.
o If your vehicle becomes stuck in snow, mud, sand, etc., then youmay attempt to rock the vehiclefree by moving it forward and back- ward. Do not attempt this proce- dure if people or objects are any-where near the vehicle. During the rocking operation the vehicle may suddenly move forward of back-ward as it becomes unstuck, caus- ing injury or damage to nearby people or objects.

!WARNING:
ABS (ESP) will not prevent accidents due to improper or dangerous driv- ing maneuvers. Even though vehiclecontrol is improved during emer- gency braking, always maintain a safe distance between you and ob-jects ahead. Vehicle speeds should always be reduced during extreme road conditions. The braking distance for cars equipped with an anti-lock braking system (Electronic Stability Program)may be longer than for those without it in the following road conditions. During these conditions, the ve-hicle should be driven at reduced speeds.
o Rough, gravel or snow-covered roads.
o With tire chains installed.
o On roads where the road surface
is pitted or has different surface height. The safety features of an ABS (ESP) equipped vehicle should not be testedby high speed driving or cornering. This could endanger the safety of yourself or others.
ANTI-LOCK BRAKE SYSTEM
C120A01FC-GAT (If Installed) The Anti-Lock Brake System (ABS) is designed to prevent wheel lock-upduring sudden braking or on hazard- ous road surfaces. The ABS control module monitors the wheel speed andcontrols the pressure applied to each brake. Thus, in emergency situations or on slick roads, ABS will increasevehicle control during braking. NOTE:
o A click sound may be heard in the engine compartment when the ve- hicle begins to move after the en- gine is started. These conditionsare normal and indicate that the anti-lock brake system (Electronic Stability Program) is functioningproperly.
o During ABS (ESP) operation, a
slight pulsation may be felt in thebrake pedal when the brakes are applied. Also, a noise may be heard in the engine compartment whilebraking. These conditions are normal and indicate that the anti- lock brake system (Electronic Sta-bility Program) is functioning prop- erly.

!
CAUTION:
Driving with varying tire or wheel size may cause the ESP system to malfunction. When replacing tires,make sure they are the same size as your original tires.!
ELECTRONIC STABILITY PROGRAM (ESP)
C310A01JM-AAT (If Installed) It is not a substitute for safe driving practices. Factors including speed, roadconditions and driver steering input can all affect whether ESP will be effective in preventing a loss of control. It is stillyour responsibility to drive and corner at reasonable speeds and to leave a sufficient margin of safety.
B310A01MC C310B01JM-AAT ESP ON/OFF Mode When the ESP is operating, the ESP indicator in the instrument cluster willblink. If you turn the system off by pressing the ESP switch, the ESP-OFF indica-tor will come on and stay on. In the ESP-OFF mode, the stability control will be deactivated. Adjust your drivingaccordingly. To turn the system back on, press the switch again. The ESP- OFF indicator should go off. NOTE: The ESP mode will automatically be turned ON after the engine is turnedoff and restarted.
The Electronic Stability Program (ESP)system is designed to stabilize thevehicle during cornering maneuvers. ESP checks where you are steering and where the vehicle is actually going.ESP applies the brakes at individual wheels and intervenes in the engine management system to stabilize thevehicle. The Electronic Stability Program (ESP) system is an electronic system de- signed to help the driver maintain ve- hicle control under adverse conditions. WARNING:
Electronic stability program is onlya driving aid; all normal precautionsfor driving in inclement weather and on slippery road surfaces should be observed.

C310D01JM-AAT Indicators and Warning The indicators should illuminate when the ignition key is turned to ON orSTART but should go out after three seconds. If the indicators do not illuminate, or theESP or ESP-OFF indicator does not go out after 3 seconds, have the vehicle checked by an authorized dealer. Should there be any unusual conditions in the device while driving, ESP-OFFindicator illuminates as a warning. If ESP-OFF indicator illuminates, pull your car to a safe place and stop theengine. Then, start the engine again to check if the ESP-OFF indicator goes out. If the indicator remains lit even after the engine has been started, have your carchecked by an authorized Hyundai dealer.
BACK WARNING SYSTEM
C400A02P-GAT (If Installed) The back warning system assists the driver during backward movement ofthe vehicle by chiming if any object is sensed within a distance of 120 cm (47 in.) behind the vehicle. This system isa supplemental system and it is not intended to nor does it replace the need for extreme care and attention of thedriver. The sensing range and objects detectable by the back sensors are limited. Whenever backing-up, pay asmuch attention to what is behind you as you would in a vehicle without a back warning system. OMC025109
WARNING:
The Back Warning System is a supple-mentary function only. The opera-tion of the Back Warning System can be affected by several factors (in- cluding environmental conditions).It is the responsibility of the driver to always check the area behind the vehicle before backing up.
Sensor Operation of the back warning system Operating condition
o This system will activate when back-ing up with the ignition key ON.If the vehicle is moving at a speedover 5 km/h (3 mph), the system may not be activated correctly.
o The sensing distance while the Back
Warning System is in operation isapproximately 120 cm (47 in.).
o When more than two objects are
sensed at the same time, the closestone will be recognized first.

o Don't coast down hills with the carout of gear. This is extremely haz- ardous. Keep the car in gear at all times, use the brakes to slow down, then shift to a lower gear so thatengine braking will help you main- tain a safe speed.
o Don't "ride" the brake pedal. Rest- ing your foot on the brake pedalwhile driving can be dangerous be- cause it can result in the brakesoverheating and losing their effec- tiveness. It also increases the wear of the brake components.
o If a tire goes flat while you are driving, apply the brakes gently and
keep the car pointed straight aheadwhile you slow down. When you are moving slowly enough for it to be safe to do so, pull off the road andstop in a safe place.
o If your car is equipped with an auto-
matic transaxle, don't let your carcreep forward. To avoid creeping forward, keep your foot firmly on the
brake pedal when the car is stopped.
o Use caution when parking on a hill. Engage the parking brake and placethe gear selector lever in "P" (auto-matic transaxle) or in first or reverse gear (manual transaxle). If your caris facing downhill, turn the frontwheels into the curb to help keep the car from rolling. If your car is facing
uphill, turn the front wheels awayfrom the curb to help keep the car from rolling. If there is no curb or if it is requiredby other conditions to keep the car from rolling, block the wheels.
o Under some conditions your park- ing brake can freeze in the engagedposition. This is most likely to hap- pen when there is an accumulationof snow or ice around or near the rear brakes or if the brakes are wet. If there is a risk that the parkingbrake may freeze, apply it only tem- porarily while you put the gear se- lector lever in "P" (automatic) or infirst or reverse gear (manual transaxle) and block the rear wheels so the car cannot roll. Then releasethe parking brake.
o Do not hold the vehicle on the up-
grade with the accelerator pedal.This can cause the transmission to overheat. Always use the brake pedal or parking brake.DRIVING FOR ECONOMY
C140A01A-GAT You can save fuel and get more kilo- meters 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 shiftsand maintain a steady cruising speed. Don't race between stop- lights. Try to adjust your speed tothat of the other traffic so you don't have to change speeds unneces- sarily. Avoid heavy traffic wheneverpossible. Always maintain a safe distance from other vehicles so you can avoidunnecessary braking. This also re- duces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel yourcar uses. Driving at a moderate speed, especially on the highway, isone of the most effective ways to reduce fuel consumption.

o Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too high a gear resulting in the engine bucking. If this happens, shift to a lower gear. Over-revving is racingthe engine beyond its safe limit. This can be avoided by shifting at the recommended speeds.
o Use your air conditioning sparingly. The air conditioning system is oper-ated by engine power so your fueleconomy is reduced when you use it.
more frequent maintenance is re- quired (see Section 5 for details).
o Keep your car clean. For maximum service, your Hyundai should bekept clean and free of corrosivematerials. It is especially important that mud, dirt, ice, etc. not be al- lowed to accumulate on the under-side of the car. This extra weight can result in increased fuel con- sumption and also contribute to cor-rosion.
o Travel lightly. Don't carry unneces-
sary weight in your car. Weight re-duces fuel economy.
o Don't let the engine idle longer than
necessary. If you are waiting (andnot in traffic), turn off your engine and restart only when you're ready to go.
o Remember, your Hyundai does not require extended warm-up. As soonas the engine is running smoothly,you can drive away. In very cold weather, however, give your engine a slightly longer warm-up period.
o Don't "ride" the brake or clutch pedal.
This can increase fuel consumptionand also increase wear on these components. In addition, driving with your foot resting on the brake pedalmay cause the brakes to overheat, which reduces their effectiveness and may lead to more serious con-sequences.
o Take care of your tires. Keep them
inflated to the recommended pres-sure. Incorrect inflation, either too much or too little, results in unnec- essary tire wear. Check the tire pres-sures at least once a month.
o Be sure that the wheels are aligned
correctly. Improper alignment canresult from hitting curbs or driving too fast over irregular surfaces. Poor alignment causes faster tire wearand may also result in other prob- lems as well as greater fuel con- sumption.
o Keep your car in good condition. For better fuel economy and reducedmaintenance costs, maintain yourcar in accordance with the mainte- nance schedule in Section 5. If you drive your car in severe conditions,

20WINTER DRIVINGSMOOTH CORNERING
C150A01A-AAT Avoid braking or gear changing in cor- ners, especially when roads are wet. Ideally, corners should always be taken under gentle acceleration. If you followthese suggestions, tire wear will be held to a minimum. C160A01A-AAT The more severe weather conditions of winter result in greater wear and other problems. To minimize the prob- lems of winter driving, you should fol-low these suggestions: C160B01A-GAT Snowy or Icy Conditions To drive your vehicle in deep snow, it may be necessary to use snow tires orto install tire chains on your tires. If snow tires are needed, it is necessary to select tires equivalent in size andtype to the original equipment tires. Failure to do so may adversely affect the safety and handling of your car.Speeding, rapid acceleration, sudden brake applications, and sharp turns are potentially very hazardous prac-tices. During deceleration, use engine braking to the fullest extent. Sudden brake applications on snowy or icyroads may cause skids to occur. You need to keep sufficient distance be- tween the vehicle in front and yourvehicle. Also, apply the brake gently. It should be noted that installing tire chains on the tire will provide a greater driving force, but will not prevent sideskids. NOTE: Tire chains are not legal in all prov- inces. Check province laws beforefitting tire chains. C160C01A-AAT Use High Quality Ethylene Glycol Coolant Your Hyundai is delivered with high quality ethylene glycol coolant in the cooling system. It is the only type of coolant that should be used because ithelps prevent corrosion in the cooling system, lubricates the water pump and prevents freezing. Be sure to replaceor replenish your coolant in accor- dance with the maintenance schedule in Section 5. Before winter, have yourcoolant tested to assure that its freez- ing point is sufficient for the tempera- tures anticipated during the winter.

C160H01A-AAT Use Approved Anti-Freeze in Window Washer System To keep the water in the window washer system from freezing, add an approvedanti-freeze solution in accordance with instructions on the container. Window washer anti-freeze is available fromHyundai dealers and most auto parts outlets. Do not use engine coolant or other types of anti-freeze as thesemay damage the finish. C160I01A-AAT Don't Let Your Parking Brake Freeze Under some conditions your parking brake can freeze in the engaged posi- tion. This is most likely to happen when there is an accumulation of snowor ice around or near the rear brakes or if the brakes are wet. If there is a risk the parking brake may freeze, apply itonly temporarily while you put the gear selector lever in "P" (automatic) or in first or reverse gear (manual transaxle)and block the rear wheels so the car cannot roll. Then release the parking brake.
C160G01A-GAT To Keep Locks from Freezing To keep the locks from freezing, squirt an approved de-icer fluid or glycerine into the key opening. If a lock is cov- ered with ice, squirt it with an approvedde-icing fluid to remove the ice. If the lock is frozen internally, you may be able to thaw it out by using a heatedkey. Handle the heated key with care to avoid injury. NOTE: The proper temperature for using the immobilizer key is from -40°C (-40°F) to 80°C(176°F). If you heat the immobilizer key over 80°C(176°F) to open the frozen lock, it may cause damage to the transpon- der in its head.
C160F01A-AAT Check Spark Plugs and Ignition System Inspect your spark plugs as described in Section 6 and replace them if neces-sary. Also check all ignition wiring and components to be sure they are not cracked, worn or damaged in any way.
C160D01A-AAT Check Battery and Cables Winter puts additional burdens on the battery system. Visually inspect thebattery and cables as described in Section 6. The level of charge in your battery can be checked by your Hyun-dai dealer or a service station. C160E01A-AAT Change to "Winter Weight" Oil if Necessary In some climates it is recommended that a lower viscosity "winter weight"oil be used during cold weather. See Section 9 for recommendations. If you aren't sure what weight oil you shoulduse, consult your Hyundai dealer.

22HIGHER SPEED MOTORING
C160K01A-AAT Carry Emergency Equipment Depending on the severity of the weather where you drive your car, you should carry appropriate emergencyequipment. Some of the items you may want to carry include tire chains, tow straps or chains, flashlight, emer-gency flares, sand, a shovel, jumper cables, a window scraper, gloves, ground cloth, coveralls, a blanket, etc.
C160J01A-AAT Don't Let Ice and Snow Accumu- late Underneath Under some conditions, snow and ice can build up under the fenders andinterfere with the steering. When driv- ing in severe winter conditions where this may happen, you should periodi-cally check underneath the car to be sure the movement of the front wheels and the steering components is notobstructed.
C170A01A-AAT Pre-Trip Inspections 1. Tires: Adjust the tire inflation pressures to specification. Low tire inflation pres-sures will result in overheating and possible failure of the tires. Avoid using worn or damaged tireswhich may result in reduced traction or tire failure. NOTE: Never exceed the maximum tire in- flation pressure shown on the tires.
2. Fuel, engine coolant and
engine oil:
High speed travel consumes more fuel than urban motoring. Do not forget tocheck both engine coolant and engine oil. 3. Drive belt: A loose or damaged drive belt may result in overheating of the engine.USE OF LIGHTS
C180A01A-AAT Check your lights regularly for correct operation and always keep them clean. When driving during the day in condi- tions of poor visibility, it is helpful todrive with headlights on low beam. This enables you to be seen as well as to see.

C190C03S-GAT Trailer Brakes If your trailer is equipped with a braking system, make sure it conforms to fed-eral and/or local regulations and that it is properly installed and operating cor- rectly. NOTE: If you tow a trailer or vehicle, your car will require more frequent main-tenance due to the additional load. See "Maintenance Under Severe Usage Conditions" on page 5-7.
CAUTION:
o Never connect a trailer brake sys- tem directly to the vehicle brakesystem.
o When towing a trailer on steep
grades (in excess of 6%) pay closeattention to the engine coolant temperature gauge to ensure the engine does not overheat. If theneedle of the coolant temperature gauge moves across the dial to- wards "H" (HOT), pull over andstop as soon as it is safe to do so,

TRAILER OR VEHICLE TOWING
C190A02A-GAT If you are considering towing with your car, you should first check with your Province Department of Motor Vehicles to determine their legal requirements.Since laws vary from province to prov- ince, the requirements for towing trail- ers, cars, other types of vehicles, orapparatus may differ. Ask your Hyundai dealer for further details before towing. C190B01S-AAT Trailer Hitches Select the proper hitch and ball combi- nation, making sure that it's location iscompatible with that of the trailer or vehicle being towed. Use a quality non-equalizing hitch whichdistributes the tongue load uniformly throughout the chassis. The hitch should be bolted securely to the car and installed by a qualified technician. DO NOT USE A HITCHDESIGNED FOR TEMPORARY IN- STALLATION AND NEVER USE ONE THAT ATTACHES ONLY TO THEBUMPER.
!
CAUTION
Do not do any towing with your car during its first 2,000 km (1,200 miles)in order to allow the engine to prop- erly break in. Failure to heed this caution may result in serious en-gine or transaxle damage.
