B750B02Y-AAT Using a cellular phone or a two-way radio When a cellular phone is used inside the ve- hicle, noise may be produced from the audioequipment. This does not mean that somethingis wrong with the audio equipment. In such acase, use the cellular phone at a place as far aspossible from the audio equipment. CAUTION: When using a communication system suchas a cellular phone or a radio inside thevehicle, a separate external antenna mustbe fitted. When a cellular phone or a radioset is used with an internal antenna alone, itmay interfere with the vehicle's electricalsystem and adversely affect safe operationof the vehicle. WARNING: Don't use a cellular phone when you aredriving, you must stop at a safe place to usea cellular phone.

o Station Swapping - As an FM signal weak- ens, another more powerful signal near the same frequency may begin to play. This isbecause your radio is designed to lock ontothe clearest signal. If this occurs, selectanother station with a stronger signal.
o Multi-Path Cancellation - Radio signals be- ing received from several directions cancause distortion or fluttering. This can becaused by a direct and a reflected signalfrom the same station, or by signals fromtwo stations with close frequencies. If thisoccurs, select another station until the con-dition has passed.SSAR013A
o Fading - As your car moves away from the radio station, the signal will weaken and sound will begin to fade. When this occurs,we suggest that you select another strongerstation.
o Flutter/Static - Weak FM signals or large obstructions between the transmitter andyour radio can disturb the signal causingstatic or fluttering noises to occur. Reducingthe treble level may lessen this effect untilthe disturbance clears.

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.

2- 4 C070A02A-AAT OPERATING THE MANUAL TRANSAXLE
HFC3029
Your Hyundai's manual transaxle has a conven- tional shift pattern. This shift pattern is imprinted on the shift knob. The transaxle is fully synchro- nized in all forward gears so shifting to either a higher or a lower gear is easily accomplished.
C055B01B-GAT STARTING AND STOPPING THE ENGINE FOR TURBO CHARGER INTERCOOLER (DIESEL ENGINE)
(1) Do not race the engine or sudden accelerate
the engine immediately after start it. If the engine is cold, allow the engine to idle for several seconds before it is driven to ensure sufficient lubrication of the turbo charger unit.
(2) After high speed or extended driving, requir- ing a heavy engine load, the engine should be allowed to idle about 1 minute before turning it off.
NOTE: If the engine were not started 10 seconds after the preheating is completed, turn the ignition key once more to the "LOCK" posi- tion, and then to the "ON" position, in order to preheat again. WARNING: Be sure that the clutch is fully depressed when starting a manual transaxle vehicle. Otherwise there is the potential to cause damage to the vehicle or injury to someone inside or outside the vehicle as a result of the forward or backward movement of the vehi- cle that will occur if the clutch is not de- pressed when the vehicle is started.
5. Turn the ignition key to the "Start" position
and release it when the engine starts. This idle time will allow the turbo charger to cool prior to shutting the engine off.
WARNING: Do not turn the engine off immediately after it has been subjected to a heavy load. Doing so may cause severe damage to the engine or turbo charger unit. NOTE:
o To shift into reverse, rest the lever in
neutral for at least 3 seconds after yourcar is completely stopped. Then move the lever into the reverse position.
o During cold weather, shifting may be dif- ficult until the transaxle lubricant has warmed up. This is normal and not harm- ful to the transaxle.
o If you 've come to a complete stop and it's hard to shift into 1 st
or R(Reverse), put the
shift lever in N(Neutral) position and re-lease the clutch. Press the clutch pedal back down, and then shift into 1 st
or
R(Reverse) gear position.
o Do not use the shift lever as a handrest during driving, as this can result in prema-ture wear of the transaxle shift forks.
CAUTION: When downshifting from fifth gear to fourth gear, caution should be taken not to inadvert- ently press the gear shift lever sideways in such a manner that second gear is engaged. Such a drastic downshift may cause the en- gine speed to increase to the point that the tachometer will enter the red zone. Such over-revving of the engine may possibly cause engine damage.

DRIVING YOUR HYUNDAI 2- 5
C070B01A-AAT Using the Clutch The clutch should be pressed all the way to the floor before shifting, then released slowly. The clutch pedal should always be used after fully returning to the original position. Do not rest your foot on the clutch pedal while driving. This can cause unnecessary wear. Do not partially en- gage the clutch to hold the car on an incline. This causes unnecessary wear. Use the parking brake to hold the car on an incline. Do not operate the clutch pedal rapidly and repeatedly. C070E03A-GAT RECOMMENDED SHIFT POINTS

The shift points as shown above are recom- mended for optimum fuel economy and perfor- mance. C070D02A-AAT Good Driving Practices
o Never take the car out of gear and coast down
a hill. This is extremely hazardous. Always leave the car in gear.
o Don't "ride" the brakes. This can cause them
to overheat and malfunction. Instead, when you 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. This will help avoid over-revving the engine, which can cause damage.
o Slow down when you encounter cross winds.
This gives you much better control of your car.
o Be sure the car is completely stopped before you attempt to shift into reverse. The transaxle can be damaged if you do not. To shift into reverse, depress the clutch, move the shift lever to neutral, wait three seconds, then shift to the reverse position.
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.
WARNING:
o The risk of rollover is greatly increased if you lose control of your vehicle at high-way speeds. C090A01A-GAT AUTOMATIC TRANSAXLE
C090A01FC
The highly efficient Hyundai automatic transaxle has four forward speeds and one reverse speed. It has a conventional shift pattern as shown in the illustration. At night, with the first position of the multi-function switch, the appropriate symbol on the shift pattern indicator will be illuminated ac- cording to the range selected.
o Loss of control often occurs if two or more
wheels drop off the roadway and the driv- er oversteers to reenter the roadway.
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.

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.

DRIVING YOUR HYUNDAI
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
