C090F02GK-GAT Sports Mode
HGK175
Whether the vehicle is stationary or in motion, sports mode is selected by pushing the selectorlever from the "D" position into the manual gate.To return to "D" range operation, push the selec-tor lever back into the main gate.In sports mode, moving the selector lever back-wards and forwards can make rapid gearshiftssimple. In contrast to a manual transaxle, thesports mode allows gearshifts with the accelera-tor pedal depressed.UP (+) : Push the lever forward once to shift up
one gear.DOWN (-) : Pull the lever backwards once to shift
down one gear.
C090E01O-AAT
o D(Drive):Use for normal driving. The transaxle will auto- matically shift through a four gear sequence.
CAUTION:
o In sports mode, the driver must execute
shifts in accordance with prevailing roadconditions, taking care to keep the enginespeed below the red zone.
o For engine protection, upward shifts are made automatically when the engine rpmreaches the red zone.
o By rapidly moving the selector lever back- wards (-) twice it is possible to skip onegear by using the sports mode. Sincesudden engine braking and/or rapid ac-celeration can cause a loss of traction,however, downshifts must be made care-fully in accordance with the vehicle'sspeed.
NOTE:
o In sports mode, only the four forward gears can be selected. To reverse or parkthe vehicle, move the selector lever to the"R" or "P" position as required.
o In sports mode, downward shifts are made automatically when the vehicle slowsdown. When the vehicle stops, 1st gear isautomatically selected.
o To maintain the required levels of vehicle performance and safety, the system maynot execute certain gearshifts when theselector lever is operated.
C090H01L-GAT NOTE:
o For smooth and safe operation, depressthe brake pedal when shifting from "Neu- tral" position or "Park" position to a for-ward or reverse gear.
o The ignition key must be in the "ON" position and the brake pedal fully de-pressed in order to move the shift leverfrom the "P" (Park) position to any of theother positions.
o It is always possible to shift from "R", "N", "D" position to "P" position. The vehiclemust be fully stopped to avoid transaxledamage.
o Before driving away from a stop on a
slippery road, push the selector lever for-ward into the +(UP) position. This causesthe transaxle to shift into 2nd gear whichis better for smooth driving away on aslippery road. Push the selector lever tothe -(DOWN) side to shift back to 1st gear.

also increases the wear of the brake compo- nents.
o If a tire goes flat while you are driving, apply the brakes gently and keep the car pointedstraight ahead while you slow down. When
you are moving slowly enough for it to be safeto do so, pull off the road and stop in a safeplace.
o If your car is equipped with an automatic transaxle, don't let your car creep forward. Toavoid creeping forward, keep your foot on thebrake pedal when the car is stopped.
o Use caution when parking on a hill. Engage the parking brake and place the gear selectorlever in "P" (automatic transaxle) or in first or
reverse gear (manual transaxle). If your car isfacing downhill, turn the front wheels into thecurb to help keep the car from rolling. If yourcar 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 required by otherconditions to keep the car from rolling, blockthe wheels.
o Under some conditions your parking brake can freeze in the engaged position. This ismost likely to happen when there is an accu-mulation of snow or ice around or near therear brakes or if the brakes are wet. If there isa risk that the parking brake may freeze,apply it only temporarily while you put thegear selector lever in "P" (automatic) or in firstor reverse gear (manual transaxle) and blockthe rear wheels so the car cannot roll. Thenrelease the parking brake. o Do not hold the vehicle on the upgrade with
the accelerator pedal. This can cause thetransmission to overheat. Always use thebrake pedal or parking brake.
C120A02A-AAT ANTI-LOCK BRAKE SYSTEM (If Installed) The Anti-Lock Brake System (ABS) is designed to prevent wheel lock-up during sudden brakingor on hazardous road surfaces. The ABS controlmodule monitors the wheel speed and controlsthe pressure applied to each brake. Thus, inemergency situations or on slick roads, ABS willincrease vehicle control during braking. NOTE: During ABS operation, a slight pulsation maybe felt in the brake pedal when the brakes areapplied. Also, a noise may be heard in theengine compartment while braking. Theseconditions are normal and indicate that theanti-lock brake system is functioning proper-ly. WARNING:Your ABS will not prevent accidents due toimproper or dangerous driving maneuvers.Even though vehicle control is improved dur-ing emergency braking, always maintain asafe distance between you and objects ahead.Vehicle speeds should always be reducedduring extreme road conditions.The braking distance for cars equipped withan anti-lock braking system may be longerthan for those without it in the following roadconditions.During these conditions the vehicle shouldbe driven at reduced speeds.
o Driving on rough, gravel or snow-covered
roads.
o Driving on with tire chains installed.
o Driving on roads where the road surface is pitted or has different surface height.
The safety features of an ABS equipped ve-hicle should not be tested by high speeddriving or cornering. This could endanger thesafety of yourself or others.

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.

9. If the trailer has electric brakes, start your
vehicle and trailer moving, and then apply the trailer brake controller by hand to be sure thebrakes are working. This lets you check yourelectrical connection at the same time.
10. During your trip, check occasionally to be sure that the load is secure, and that thelights and any trailer brakes are still working.
11. Avoid jerky starts, sudden acceleration or sudden stops.
12. Avoid sharp turns and rapid lane changes.
13. Avoid holding the brake pedal down too long or too frequently. This could cause the brakesto overheat, resulting in reduced braking effi-ciency.
14. When going down a hill, shift into a lower gear and use the engine braking effect.When ascending a long grade, downshift thetransmission to a lower gear and reducespeed to reduce chances of engine overload-ing and/or overheating.
15. If you have to stop while going uphill, do not hold the vehicle in place by pressing on theaccelerator. This can cause the automatictransmission to overheat. Use the parkingbrake or footbrake. NOTE:When towing check transaxle fluid more fre-quently. CAUTION: If overheating should occur when towing,(temperature gauge reads near red zone),taking the following action may reduce oreliminate the problem.
1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going uphill.
4. While in stop and go traffic, place the gear
selector in park or neutral and idle theengine at a higher speed.
