o When the air flow rate is suddenly de- creased, it must be checked at an autho-rized dealer.
B740D01A-AAT Operation Tips
o If the interior of the car is hot when you first get in, open the windows for a few minutes to expel the hot air.
o When you are using the air conditioning system, keep all windows closed to keep hotair out.
o When moving slowly, as in heavy traffic, shift to a lower gear. This increases enginespeed, which in turn increases the speed ofthe air conditioning compressor.
o On steep grades, turn the air conditioning off to avoid the possibility of the engine over-heating.
o During winter months or in periods when the air conditioning is not used regularly, run theair conditioning once every month for a fewminutes. This will help circulate the lubri-cants and keep your system in peak operat-ing condition.

WARNING: ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the windows immediately. o Do not inhale exhaust fumes. Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxiation. o Be sure the exhaust system does not leak. The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you hear a change in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, have the exhau st
system checked as soon as possible by your Hyundai dealer. o Do not run the engine in an enclosed area. Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine in your garage any longer than it takes to start the engine and back the car out. o Avoid idling the engine for prolonged periods with people inside the car. If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area with
the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior. If you must drive with the tail gate open because you are carrying objects that make this necessary:1. Close all windows. 2. Open side vents. 3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshield are kept clear of snow, ice, leaves or other obstructions.

C030A01A-GAT COMBINATION IGNITION SWITCH To Start the Engine Before starting the engine:
o If your Hyundai is equipped with a manual transaxle, place the shift lever in neutral and depress the clutch pedal fully.
o If your Hyundai has an automatic transaxle,
place the shift lever in "P" (park).
o To start the engine, insert the ignition key and
turn it to the "START" position. Release it as soon as the engine starts. Do not hold the key in the "START" position for more than 15 seconds.
NOTE: For safety, the engine will not start if the shift lever is not in "P" or "N" Position (automatic transaxle).

DRIVING YOUR HYUNDAI 2- 7
C090I02A-AAT CAUTION:
o Shift into "R" and "P" position only when
the vehicle has completely stopped.
o Do not accelerate the engine in reverse or
any of the forward positions with the brakes applied.
o Always apply the footbrake when shifting from "P" or "N", to "R", "D", "2" or "L" position.
o Do not use the "P" (Park) position in place
of the parking brake. Always set the park- ing brake, shift the transaxle into "P" (Park) position and turn off the ignition when you leave the vehicle, even momentarily. Never leave the vehicle unattended while the engine is running.
o Check the automatic transaxle fluid level regularly, and add fluid as necessary. See the maintenance schedule for the proper fluid recommendation.
C090N02A-AAT Good Driving Practices
o Never move the gear selector lever from "P" or "N" to any other position with the acceler- ator pedal depressed.
o Never move the gear selector lever into "P"
when the vehicle is in motion.
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 extremely hazardous. Always leave the car in gear when moving. o Do not "ride" the brakes. This can cause them
to overheat and malfunction. Instead, whenyou are driving down a long hill, slow down and shift 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 may not be en- gaged.
o Always use the parking brake. Do not depend
on placing the transaxle in "P" to keep the car from moving.
o Exercise extreme caution when driving on a slippery surface. Be especially careful when braking, accelerating or shifting gears. On a slippery surface, an abrupt change in vehicle speed can cause the drive wheels to lose traction and the vehicle to go out of control.
o Turn the overdrive switch on for good fuel economy and smooth driving. If engine brak- ing is needed in the "D" range or if repeated upshifting and downshifting between 3rd and 4th gear is needed when climbing a gentle slope, it is recommended that the overdrive switch be turned off. Turn the overdrive switch back on immediately afterward.
WARNING:
o The risk of rollover is greatly increased if you lose control of your vehicle at high-way speeds.
o Loss of control often occurs if two or more
wheels drop off the roadway and the driv- er oversteers to reenter the roadway. C090P01A-GAT Overdrive Switch
HFC3023
When the overdrive switch is turned on, the transaxle will automatically upshift to the second, third and overdrive gears. When the overdrive switch is turned off, the transaxle will not upshift to the overdrive gear. For normal driving, the selector lever should be left in the "D" position and the overdrive switch turned on. If you need to accelerate rapidly, press the accel- erator pedal all the way to the floor. The transaxle will automatically shift to a lower gear, depending on the vehicle speed and load.
o In the event your vehicle leaves the road- way, do not steer sharply. Instead, slow down before pulling back into the travel lanes.
o In a collision crash, an unbelted person is
significantly more likely to die than a per- son wearing a seatbelt.

2- 8 o Do not hold the vehicle on the upgrade with
the accelerator pedal. This can cause the transmission to overheat. Always use the brake 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 braking or on hazardous road surfaces. The ABS control module monitors the wheel speed and controls the pressure applied to each brake. Thus, in emergency situations or on slick roads, ABS will increase vehicle control 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 be heard in the engine compartment while braking. These conditions are normal and indicate that the anti-lock brake system is functioning proper- ly. WARNING: ABS will not prevent accidents due to im- proper or dangerous driving maneuvers. Even though vehicle control is improved during emergency braking, always maintain a safe distance between you and objects ahead. Vehicle speeds should always be reduced during extreme road conditions. The braking distance for cars equipped with
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 pointed straight ahead while you slow down. When
you are moving slowly enough for it to be safe to do so, pull off the road and stop in a safe place.
o If your car is equipped with an automatic
transaxle, don't let your car creep forward. To avoid creeping forward, keep your foot on the brake pedal when the car is stopped.
o Use caution when parking on a hill. Engage
the parking brake and place the gear selector lever in "P" (automatic transaxle) or in first or
reverse gear (manual transaxle). If your car is
facing downhill, turn the front wheels into the curb to help keep the car from rolling. If your car is facing uphill, turn the front wheels away from the curb to help keep the car from rolling. If there is no curb or if it is required by other conditions to keep the car from rolling, block the wheels.
o Under some conditions your parking brake can freeze in the engaged position. This is most likely to happen when there is an accu- mulation of snow or ice around or near the rear brakes or if the brakes are wet. If there is a risk that the parking brake may freeze, apply it only 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.
C130A01A-AAT GOOD BRAKING PRACTICES WARNING: Nothing should be carried on top of the shelf panel behind the rear seat. If there were an accident or a sudden stop, such objects could move forward and cause damage to the ve- hicle or injure the occupants.
o After being parked, check to be sure the
parking brake is not engaged and that the parking brake indicator light is out before driving away.
o Driving through water may get the brakes
wet. They can also get wet when the car is washed. Wet brakes can be dangerous! Your
car will not stop as quickly if the brakes are wet. Wet brakes may cause the car to pull to one side. To dry the brakes, apply the brakes lightly until the braking action returns to nor-
mal, taking care to keep the car under control at all times. If the braking action does not return to normal, stop as soon as it is safe to do so and call your Hyundai dealer for assis- tance.
o Don't coast down hills with the car out of gear.
This is extremely hazardous. Keep the car in gear at all times, use the brakes to slow down, then shift to a lower gear so that engine braking will help you maintain a safe speed.
o Don't "ride" the brake pedal. Resting your foot on the brake pedal while driving can be dan- gerous because it can result in the brakes overheating and losing their effectiveness. It

DRIVING YOUR HYUNDAI 2- 9
an anti-lock braking system may be longer than for those without it in the following road conditions.
o Driving on rough, gravel or snow-covered
roads.
o Driving with tire chains installed.
o Driving on roads where the road surface is pitted or has different surface height.
During these conditions, the vehicle shouldbe driven at reduced speeds. The safety fea- tures of an ABS equipped vehicle should not be tested by high speed driving or cornering. This could endanger the safety of yourself or others. C300A01O-GAT BRAKE TRACTION CONTROL SYSTEM (BTCS) (If Installed) On slippery road surfaces, the traction control system (TCS) limits the drive wheels from spin- ning excessively, thus helping the car to acceler- ate. It also provides sufficient driving force and steering performance as the car turns at acceler- ated speeds. SLIP Control Limits the drive wheels from spinning exces- sively during starting or while making accelerat- ed turns on slippery roads to avoid losing the driving force of the front wheels. C300B01O-GAT TCS ON ModeIn the TCS ON mode, the indicator in the instru- ment cluster will not be illuminated. NOTE:
1) Turn off the engine. Then restart the en-
gine, and the TCS mode will automaticallyturn "ON".
2) When the traction control is operating
properly, you can feel a slight pulsation in the vehicle. This is only the effect of brake control and indicates nothing unusual. C300D02O-GAT Indicator and Warning The indicator should illuminate when the ignition key is turned to "ON" or "START", but should 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 safe place 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 car checked 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 entering curves. CAUTION: When the TCS indicator blinks, SLIP control has been activated. It also means that the road is slippery or your car is accelerating excessively. In this situation, release foot pressure from the accelerator pedal and main- tain moderate speed. WARNING: Traction control is only a driving aid; all normal precautions for driving in inclement weather and on slippery driving surfaces should be observed.
3) When the engine starts, a click is heard
from the engine compartment; however, this is only the sound of traction control being checked.
4) When moving out of the mud or fresh
snow, pressing the accelerator pedal may not cause the engine speed to increase.

SMOOTH CORNERING
Avoid braking or gear changing in corners, espe- cially when roads are wet. Ideally, corners should always be taken under gentle acceleration. If you follow these suggestions, tire wear will be held to a minimum.
curbs or driving too fast over irregular surfac- es. Poor alignment causes faster tire wear and may also result in other problems as well as greater fuel consumption.
o Keep your car in good condition. For better
fuel economy and reduced maintenance costs, maintain your car in accordance with the maintenance schedule in Section 5. If you drive your car in severe conditions, more frequent 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 of corrosive materials. It is especially important that mud, dirt, ice, etc. not be allowed to accumulate on the underside of the car. This extra 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 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 is running smoothly, you can drive away. In very cold weather, however, give your engine a 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, shift to a lower gear. Over-revving is racing the engine beyond its safe limit. This can be C160A01A-AAT WINTER DRIVING The more severe weather conditions of winter result in greater wear and other problems. To minimize the problems of winter driving, you should follow these suggestions: C160B01A-GAT Snowy or Icy ConditionsTo drive your vehicle in deep snow, it may be necessary to use snow tires or to install tire chains on your tires. If snow tires are needed, it is necessary to select tires equivalent in size and type to the original equipment tires. Failure to do so may adversely affect the safety and handling of your car. Speeding, rapid acceleration, sud- den brake applications, and sharp turns are potentially very hazardous practices. During
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 cruising speed. Don't race between stoplights. Try to adjust your speed to that of the other traffic so you don't have to change speeds unneces- sarily. Avoid heavy traffic whenever possible. Always maintain a safe distance from other vehicles 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 at a moderate speed, especially on the high- way, is one of the most effective ways to reduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This
can increase fuel consumption and also in- crease wear on these components. In addi- tion, driving with your foot resting on the brake pedal may cause the brakes to overheat, which reduces their effectiveness and may lead 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 in unnecessary 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 hitting avoided by shifting at the recommendedspeeds.
o Use your air conditioning sparingly. The air
conditioning system is operated by engine power so your fuel economy is reduced when you use it.
