OVERDRIVE SWITCH
The overdrive switch prevents the transaxle
upshifting higher than third gear when the switch is turned "OFF". The transaxle will startfrom rest in first gear and upshift to secondand third gear depending upon the roadspeedand throttle opening but will not upshift tofourth gear. When the overdrive switch isturned "ON", the transaxle will start from restin first gear and will upshift, depending uponroadspeed and throttle opening to second,third and fourth gear. Therefore, when theoverdrive switch is turned "OFF", the transaxleperforms as a three speed unit and the over-drive warning light located in the instrumentcluster will be illuminated. When the overdriveswitch is turned "ON", the transaxle functionsas a fully automatic four speed unit with themaximum fuel economy potential of the ve-hicle being realized. o Do not hold the vehicle on the upgrade
with the accelerator pedal. This can causethe transmission to overheat. Always usethe brake pedal or parking brake.
SC140A1-E EFFECTIVE BRAKING Braking system performance and friction ma- terial life are greatly affected by the drivingstyle adopted. The following suggestions aremade to assist in achieving the best resultsfrom the braking system.
o Anticipate the road and conditions ahead
in order that heavy braking may be avoided.
o When descending long gradients, use the engine to assist in retarding the vehicle to minimize the possibility of brake fade oc-curring.
o When trailer towing, ensure that the trailer brakes function correctly and use enginebraking to assist the vehicle braking system.
o Use only genuine Hyundai replacement brake pads and shoes to ensure consis-tent friction characteristics and wear rates.
o After driving through deep water (e.g. fording), the brakes may become wet andperformance reduced. Always check brakeefficiency after emerging from the waterand dry the brakes by lightly depressingthe brake pedal several times whilst driv-ing slowly.
o Apply the parking brake only when the vehicle is at rest.
o Since the power assistance provided by the brake servo is derived from the engine,coasting with the engine turned off or tow-ing of the vehicle with the engine turned offwill result in greatly increased pedal pres-sures being required to stop the vehicle. SC140B1-E
ANTI-LOCK BRAKE SYSTEM (Not all models)
The Anti-Lock Brake System (ABS) is de-
signed to prevent wheel lock-up during sud- den braking or on hazardous road surfaces.The ABS control module monitors the wheelspeed and controls the pressure applied toeach brake. Thus, in emergency situations oron slick roads, ABS will increase vehicle con-trol during braking.
NOTE: During ABS operation, a slight pulsation
may be felt in the brake pedal when the brakes are applied. Also, a noise may beheard in the engine compartment whilstbraking. These conditions are normal andindicate that the anti-lock brake system isfunctioning properly.
WARNING:ABS will not prevent accidents due to im-
proper or dangerous driving maneuvers.Even though vehicle control is improvedduring emergency braking, always maintaina safe distance between you and objectsahead. Vehicle speeds should always bereduced during extreme road conditions.

TCS ON Mode In the TCS ON mode, the indicator in the instrument cluster will not be illuminated. NOTE:
1) Turn off the engine. Then restart the engine, and the TCS mode will auto- matically turn "ON".
2) When the traction control is operating properly, you can feel a slight pulsationin the vehicle. This is only the effect ofbrake control and indicates nothingunusual. C300D02O-GAT
Indicator and Warning
The indicator should illuminate when the igni-tion key is turned to "ON" or "START", butshould go out after three seconds. If the indicator does not illuminate, have it checked by an authorized Hyundai dealer. Should there be any unusual conditions in the device, TCS illuminates as a warning.If TCS illuminates, pull your car to a safeplace and stop the engine. Then, start the engine again to check if the TCS indicator goes out. If the indicator remains lit even after the engine has been started, have your carchecked by an authorized Hyundai dealer. NOTE: When TCS illuminates, traction control is automatically deactivated for safety.
Driving hints
TCS does not actively apply brakes. Be sure
to decelerate the car sufficiently before enter-ing curves.
CAUTION: When the TCS indicator blinks, SLIP con-
trol has been activated. It also means that the road is slippery or your car is acceler-ating excessively. In this situation, releasefoot pressure from the accelerator pedaland maintain moderate speed.
WARNING: Traction control is only a driving aid; all
normal precautions for driving in inclem- ent weather and on slippery driving sur-faces should be observed. 3) When the engine starts, a click is heard
from the engine compartment; however,this is only the sound of traction controlbeing checked.
4) When moving out of the mud or fresh snow, pressing the accelerator pedalmay not cause the engine speed toincrease.
The braking distance for cars equippedwith an anti-lock braking system may belonger than for those without it in thefollowing road conditions.
o Driving on rough, gravel or snow-cov-
ered roads.
o Driving with tyre chains installed.
o Driving on roads where the road sur- face is pitted or has different surface height.
These roads should be driven at reducedspeeds. The safety features of an ABSequipped vehicle should not be tested byhigh speed driving or cornering. This couldendanger the safety of yourself or others.

BRAKE TRACTION CONTROL SYSTEM (BTCS) (Not all models)
On slippery road surfaces, the traction control
system (TCS) limits the drive wheels from spinning excessively, thus helping the car toaccelerate. It also provides sufficient drivingforce and steering performance as the carturns at accelerated speeds. SLIP Control
Limits the drive wheels from spinning exces-
sively during starting or while making acceler- ated turns on slippery roads to avoid losingthe driving force of the front wheels.

o Don't "lug" or "over-rev" the engine. Lug-
ging is driving too slowly in too high a gear resulting in the engine bucking. If thishappens to you, shift to a lower gear. Over-revving is racing the engine beyond its safe limit. This can be avoided byshifting at the recommended speeds.
o Use your air conditioning sparingly. The air conditioning system is operated by theengine power so your fuel economy isreduced when you use it.
SC150A1-F
DRIVING FOR ECONOMY
You can save fuel and get more miles fromyour 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 cruis-ing speed. Don't race between stoplights.Try to adjust your speed to that of the othertraffic so you don't have to change speedsunnecessarily. Avoid heavy traffic whenever possible. Al- ways maintain a safe distance from othervehicles so you can avoid unnecessarybraking. This also reduces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel your car uses. Drivingat a moderate speed, especially on thehighway, is one of the most effective waysto reduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This can increase fuel consumption and alsoincrease wear on these components. Inaddition, driving with your foot resting onthe brake pedal may cause the brakes tooverheat, which reduces their effective-ness and may lead to more serious con-
sequences.
o Take care of your tyres. Keep them inflated to the recommended pressure. Incorrectinfla-tion, either too much or too little, re-sults in unnecessary tyre wear. Check thetyre pres-sures at least once a month. o Be sure that the wheels are aligned cor-
rectly. Improper alignment can result fromhitting curbs or driving too fast over irregu-lar surfaces. Poor alignment causes fastertyre wear and may also result in otherproblems as well as greater fuel consump-tion.
o Keep your car in good condition. For better fuel economy and reduced maintenancecosts, maintain your car in accordancewith the maintenance schedule in Section5. If you drive your car in severe condi-tions, more frequent maintenance is re-quired (see Section 5 for details).
o Keep your car clean. For maximum ser- vice, your car should be kept clean andfree of corrosive materials. It is especiallyimportant that mud, dirt, ice, etc. not beallowed to accumulate on the underside ofthe car. This extra weight can result inincreased fuel consumption and also con-tribute to corrosion.
o Travel lightly. Don't carry unnecessary weight in your car. Weight is an enemy ofgood fuel economy.
o Don't let the engine idle longer than neces- sary. If you are waiting (and not in traffic),turn off your engine and restart only whenyou're ready to go.
o Remember, your car does not require extended warm-up. As soon as the engineis running smoothly, you can drive away.In very cold weather, however, give yourengine a slightly longer warm-up period. SC160A1-F SMOOTH CORNERING Avoid braking or gear changing in corners, especially when roads are wet. Ideally, cor-ners should always be taken under gentleacceleration. If you follow these suggestions,tyre wear will be held to a minimum. SC170A1-E WINTER MOTORING The onset of winter conditions subject motor vehicles to greater operating demands. There-fore, the following suggestions will assist inmaintaining peak performance and reliabilityduring these periods:

5. Always secure items in the trailer to pre-
vent load shift while driving.
6. Check the condition and air pressure of all tyres on the trailer and your car. Low tyre pressure can seriously affect the handling.Also check the spare tyre.
7. The vehicle/trailer combination is more af- fected by crosswind and buffeting. When being passed by a large vehicle, keep a constant speed and steer straightahead. If there is too much wind buffetingslow down to get out of the other vehicle'sair turbulence.
8. When parking your car and trailer, espe- cially on a hill, be sure to follow all thenormal precautions. Turn your front wheelinto the curb, set the parking brake firmly,and put the transaxle in 1st or Reverse(manual) or Park (automatic). In addition,place wheel chocks at each of the trailer'styres.
9. If the trailer has electric brakes, start your vehicle and trailer moving, and then applythe trailer brake controller by hand to besure the brakes are working. This lets youcheck your electrical connection at thesame time.
10.During your trip, check occasionally to be sure that the load is secure, and that thelights and any trailer brakes are still work-ing. 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 brakes to overheat, resulting in re-duced braking efficiency.
14.When going down a hill, shift into a lower gear and use the engine braking effect. When ascending a long grade, downshift the transaxle to a lower gear and reducespeed to reduce chances of engine over-loading and/or overheating.
15.If you have to stop while going uphill, do not hold the vehicle in place by pressing onthe accelerator. This can cause the auto-matic transaxle to overheat. Use the park-ing brake or footbrake.
NOTE: When towing check transaxle fluid more frequently. 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 selection in park or neutral and idle the engine at a higher speed.
