C090F01L-GAT Sports mode Whether the vehicle is stationary or in motion, sports mode is selected bypushing the selector lever from the "D"position into the manual gate. To re-
turn to "D" range operation, push the selector lever back into the main gate.In sports mode, moving the selectorlever backwards and forwards canmake gearshifts rapidly simply. In con-trast to a manual transaxle, the sports mode allows gearshifts with the acceleator pedal depressed. HXG200
+ (UP)
- (DOWN) UP (+)
: Push the lever forward
once to shift up one gear.
DOWN (-) : Pull the lever backwards
once to shift down onegear.
SKIP : By rapidly moving the se-
lector forward or backwardtwice, it is possible to skipone gear, i.e. 1st to 3rd or3rd to 1st . NOTE:
o In sports mode, only the four/five
forward gears can be selected. To reverse or park the vehicle,move the selector lever to the "R"or "P" position as required.
o In sports mode, downward shifts are made automatically when thevehicle slows down. When thevehicle stops, 1st gear is auto-matically selected.
o To maintain the required levels
of vehicle performance and safety, the system may not ex- ecute certain gearshifts when theselector lever is operated.
o When driving away on a slippery road, push the selector lever to-ward into the +(UP) position. This cause the transaxle to shift into the 2nd gear which is better forsmooth driving away on a slip-pery road. Push the selector le-ver to the -(DOWN) side to shiftback to the 1st gear.
! CAUTION:
o Upward shifts do not take place automatically in sports mode. The driver must execute upward shifts in accordance with prevailing road conditions, taking care tokeep the engine speed below thered zone.
o By rapidly moving the selector lever backwards (-) twice, it is possible to skip one gear, i.e., 3rd to 1st, 4th to 2nd or 5th to 3rd.Since sudden engine brakingand/or rapid acceleration can
cause a loss of traction, how-ever, downshifts must be made carefully in accordance with the vehicle's speed.

C190C01Y-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 SevereUsage Conditions" on page 5-6.
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 12%) pay
close attention to the engine cool- ant temperature gauge to ensure
the engine does not overheat. Ifthe needle of the coolant tem-
perature gauge moves across thedial towards "H" (HOT), pull over and stop as soon as it is safe to
C190B01S-AATTrailer Hitches Select the proper hitch and ball combi- nation, making sure that it's location is compatible with that of the trailer or vehicle being towed.Use a quality non-equalizing hitch whichdistributes the tongue load uniformlythroughout the chassis. The hitch should be bolted securely to the car and installed by a qualifiedtechnician. DO NOT USE A HITCHDESIGNED FOR TEMPORARY IN-STALLATION AND NEVER USE ONETHAT ATTACHES ONLY TO THE BUMPER.
C180A01A-AAT USE OF LIGHTS 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. C190A01A-GAT TRAILER OR VEHICLE TOWING If you are considering towing with your car, you should first check with your Province Department of Motor Vehiclesto determine their legal requirements.Since laws vary from province to prov-ince the requirements for towing trail- ers, cars, or other types of vehicles or apparatus may differ. Ask your Hyundaidealer for further details before towing.
CAUTION:
Do not do any towing with your carduring its first 2,000 km (1,200 miles)in order to allow the engine to prop-erly break in. Failure to heed thiscaution may result in serious en- gine or transaxle damage.

WARNING:
Improperly loading your car and trailer can seriously affect its steer-ing and braking performance caus- ing a crash which could cause seri- ous injury or death. C190F01Y-GAT Trailer or Vehicle Towing Tips
1. Before towing, check hitch and
safety chain connections as well as proper operation of the trailer run-ning lights, brake lights, and turnsignals.
2. Always drive your vehicle at a mod-
erate speed (Less than 100 km/h)
3. Trailer towing requires more fuel
than normal conditions.
4. To maintain engine braking effi-
ciency and electrical charging per- formance, do not use fifth gear (manual transaxle).
5. Always secure items in the trailer to prevent load shift while driving.
6. Check the condition and air pres-
sure of all tires on the trailer and your car. Low tire pressure can seriously affect the handling. Alsocheck the spare tire.
7. The vehicle/trailer combination is more affected by crosswind andbuffeting. When being passed by a large ve- hicle, keep a constant speed andsteer straight ahead. If there is toomuch wind buffeting slow down to

GAWR. Improper trailer loadingand/or too much luggage in thetrunk can overload the rear axle.Redistribute the load and checkthe axle weight again.
4. The maximum permissible static
vertical load on the coupling de-vice is 75 kg. CAUTION:
The following specifications are rec-ommended when towing a trailer.The loaded trailer weight cannotsafely exceed the values in the chartbelow.

14.When going down a hill, shift into a
lower gear and use the engine brak- ing effect.When ascending a long grade,downshift the transaxle to a lower gear and reduce speed to reduce chances of engine overloading and/or overheating.
15.If you have to stop while going uphill, do not hold the vehicle inplace by pressing on the accelera- tor. This can cause the automatic transaxle to overheat. Use the park-ing brake or footbrake.
NOTE: When towing, check transaxle fluid more frequently.
CAUTION:
If overheating should occur whentowing, (temperature gauge readsnear red zone), taking the followingaction may reduce or eliminate theproblem.
get out of the other vehicle's airturbulence.
8. When parking your car and trailer,
especially on a hill, be sure to followall the normal precautions. Turn your front wheel into the curb, set the parking brake firmly, and putthe transaxle in 1st or Reverse(manual) or Park (automatic). Inaddition, place wheel chocks ateach of the trailer's tires.
9. If the trailer has electric brakes,
start your vehicle and trailer mov-ing, and then apply the trailer brakecontroller by hand to be sure thebrakes are working. This lets youcheck your electrical connection at the same time.
10.During your trip, check occasion- ally to be sure that the load is secure, and that the lights and anytrailer brakes are still working.
11.Avoid jerky starts, sudden accel- eration or sudden stops.
12.Avoid sharp turns and rapid lane changes.
13.Avoid holding the brake pedal down too long or too frequently. This couldcause the brakes to overheat, re- sulting in reduced braking efficien- cy. 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 neutraland idle the engine at a higher speed.

VEHICLE MAINTENANCE REQUIREMENTS 5- 7
F060A01A-AAT EXPLANATION OF SCHEDULED MAINTENANCE ITEMS F060M01A-AAT
o Engine Oil and Filter The engine oil and filter should be changed at the intervals specified in the maintenance schedule. If the caris being driven in severe conditions,more frequent oil and filter changesare required. F060B01A-AAT
o Drive Belts Inspect all drive belts for evidence of cuts, cracks, excessive wear or oil and replace if necessary. Drive belts should be checked periodically forproper tension and adjusted as nec-essary. After installing a new filter, run theengine for several minutes, and checkfor leaks at the connections. Fuelfilters should be installed by trainedtechnicians. F060D01A-AAT
o Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and connections for leakage and damage. Have a trained technician replace anydamaged or leaking parts immedi-ately. F060E01A-AAT
o Timing Belt Inspect all parts related to the timing belt for damage and deformation.Replace any damaged parts immedi-ately. F060G01A-AAT
o Vapor Hose and Fuel Filler Cap The vapor hose and fuel filler cap should be inspected at those inter-vals specified in the maintenanceschedule. Make sure that a new va-por hose or fuel filler cap is correctlyreplaced. F060F01A-AAT
o Vacuum, Crankcase Ventila-
tion Hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical dam-age. Hard and brittle rubber, crack-ing, tears, cuts, abrasions, and ex- cessive swelling indicate deteriora- tion. Particular attention should bepaid to examine those hose surfacesnearest to high heat sources, such asthe exhaust manifold. Inspect the hose routing to assure
that the hoses do not come in contactwith any heat source, sharp edges ormoving component which might cause heat damage or mechanical wear. Inspect all hose connections, such asclamps and couplings, to make surethey are secure, and that no leaks arepresent. Hoses should be replacedimmediately if there is any evidence of deterioration or damage.
F060C01A-AAT
o Fuel Filter A clogged filter can limit the speed at which the vehicle may be driven, dam-age the emission system and causehard starting. If an excessive amountof foreign matter accumulates in thefuel tank, the filter may require re- placement more frequently.

DO-IT-YOURSELF MAINTENANCE 6- 9
G050D02A-AAT To Change the Engine Coolant The engine coolant should be changed at those intervals specified in the ve- hicle maintenance schedule in Sec-tion 5.
CAUTION:
Engine coolant can damage thefinish of your car. If you spill en- gine coolant on the car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking brake and remove the radiator cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on theradiator. Allow all the engine coolant to drain from the cooling system,then securely close the drain cock.
Use a high quality ethylene-glycol
coolant in a 50/50 mix with water. The engine coolant should be compatible with aluminum engine parts. Addi-tional corrosion inhibitors or additives should not be used. The cooling sys- tem must be maintained with the cor-rect concentration and type of engine coolant to prevent freezing and corro- sion.
Never allow the concentration of an-
tifreeze to exceed the 60% level or gobelow the 35% level or damage to thecoolant system may result. For proper concentration when adding or replac- ing the engine coolant, refer to thefollowing table.
