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 exhaust 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 theengine 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 trunk lid / 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 ofthe windshield are kept clear of snow, ice, leaves or other obstructions.

TO START THE ENGINEBEFORE STARTING THE ENGINE
C020A01O-GAT Before you start the engine, you should always:
1. Look around the vehicle to be sure
there are no flat tires, puddles of oil, water or other indications of pos- sible trouble.
2. After entering the car, check to be sure the parking brake is engaged.
3. Check that all windows and lights are clean.
4. Check that the interior and exterior
mirrors are clean and in position.
5. Check your seat, seatback and headrest to be sure they are in theirproper positions.
6. Lock all the doors.
7. Fasten your seat belt and be sure
that all other occupants have fas- tened theirs.
8. Turn off all lights and accessories
that are not needed. C030A01A-GAT COMBINATION IGNITION SWITCH 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 igni- tion key and turn it to the "START"position. Release it as soon as the engine starts. Do not hold the key inthe "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).
WARNING (DIESEL ENGINE):
To ensure that sufficient vacuum exists within the brake system dur- ing cold weather start-up condi-tions, it is necessary to run the engine at idle for several seconds after starting the engine.
9. When you turn the ignition switch to
"ON", check that all appropriatewarning lights are operating and that you have sufficient fuel.
10.Check the operation of warning lights and all bulbs when key is inthe "ON" position.

C090H01E-GAT NOTE:
o For smooth and safe operation,depress the brake pedal when shifting from "N" (Neutral) posi-tion or "P" (Park) position to a forward or "R" (Reverse) gear.
o The brake pedal fully depressed in order to move the shift leverfrom the "P" (Park) position to any of the other positions.
o It is always possible to shift from "R", "N", "D", "3"(1.8 / 2.0 DOHC),"2", "L" position to "P" position.The vehicle must be fully stopped to avoid trans©23
axle damage. C090I02E-GAT
CAUTION:
o Shift into "R" and "P" position only when the vehicle has com- pletely stopped.
o Do not accelerate the engine in reverse or any of the forwardpositions with the brakes applied.
o Always apply the footbrake when shifting from "P" or "N", to "R",
"D","3"(1.8 / 2.0 DOHC), "2" or"L" position.
o Do not use the "P" (Park) posi-
tion in place of the parking brake.Always set the parking brake, shift the transaxle into "P" (Park) position and turn off the ignitionwhen you leave the vehicle, even momentarily. Never leave the vehicle unattended while the en-gine is running.
o Check the automatic transaxle
fluid level regularly, and add fluidas necessary. See the maintenance schedule for the proper fluid recommen-dation.
!
C090G01S-GAT o L (Low gear): Use for driving up a very steep grade or for engine braking when descendingsteep hills. When downshifting to "L", the transaxle will temporarily remain in second gear until the vehicle hasslowed enough for low gear to engage. Do not exceed 50 km/h (30 mph) in low gear."L" shifts to 1st gear only. However, shift up to 2nd is performed when the car exceeds a certain speed and, asspeed increases, the transaxle will shift up to 3rd gear to prevent over-revving the engine.

15TRACTION CONTROL SYSTEM (TCS)
!
Driving hints TCS does not actively apply brakes. Be sure to decelerate the car suffi-ciently before entering curves.
C300A02Y-GAT (If installed)
C300A02E
!
On slippery road surfaces, the traction control system (TCS) limits the drive wheels from spinning excessively, thus helping the car to accelerate. It alsoprovides sufficient driving force and steering performance as the car turns at accelerated speeds. SLIP Control Limits the drive wheels from spinning excessively during starting or while making accelerated turns on slippery roads to avoid losing the driving forceof the front wheels. CAUTION:
When the TCS indicator blinks, SLIPcontrol has been activated. It alsomeans that the road is slippery or your car is accelerating excessively. In this situation, gently release footpressure from the accelerator pedal and maintain moderate speed.
WARNING:
Traction control is only a drivingaid; all normal precautions for driv- ing in inclement weather and onslippery driving surfaces should be observed. C310B01O-AAT TCS ON/OFF Mode When the TCS is running, the TCS indicator in the instrument cluster willblink. If you turn the system off by pressing the TCS switch, the TCS-OFF indica-tor will come on and stay on. In the TCS-OFF mode, the SLIP control will be deactivated. Adjust you driving ac-cordingly. To turn the system back on, press the switch again. The TCS-OFF indicator should go off. NOTE:
1) The TCS mode will automatically
be turned "ON" after the engine is turned off and restarted.
2) When the traction control sys-
tem is operating properly, youcan feel a slight pulsation in the vehicle. This is only the effect of brake control and indicates noth-ing unusual.
3) When the engine starts, a click is
heard from the engine compart-ment; however, this is only the sound of traction control being checked.

If the indicator remains lit even after the engine has been started, haveyour car checked by an authorized Hyundai dealer. NOTE:
1) When the TCS-OFF indicator il-luminates, traction control is au- tomatically deactivated for safety.
2) This warning function is not pro- vided when the driver selects theTCS-OFF mode.
4) When moving out of the mud or
fresh snow, pressing the accel- erator pedal may not cause the engine speed to increase due to TCS operation.
C310D01O-AAT Indicators and Warning The TCS indicators should illuminate when the ignition key is turned to "ON"or "START" but should go out after three seconds. If the indicators do not illuminate, orthe TCS or TCS-OFF indicator does not go out after 3 seconds, have it checked by an authorized dealer. Should there be any unusual condi- tions in the device while driving, TCS-OFF indicator illuminates as a warn- ing. If TCS-OFF indicator illuminates, pullyour car to a safe place and stop the engine. Then, start the engine again to checkif the TCS-OFF indicator goes out.

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 sud- den stop, such objects could move forward and cause damage to thevehicle or injure the occupants.
o After being parked, check to be sure the parking brake is not engaged and that the parking brake indicatorlight is out before driving away.
o Driving through water may get the
brakes wet. They can also get wetwhen 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 thebraking action returns to normal, taking care to keep the car under control at all times. If the brakingaction does not return to normal, stop as soon as it is safe to do so and call your Hyundai dealer forassistance.

components. In addition, driving with your foot resting on the brake pedalmay cause the brakes to overheat, which reduces their effectiveness and may lead to more serious con-sequences.
o Take care of your tires. Keep them
inflated to the recommended pres-sure. Incorrect inflation, either too much or too little, results in unnec- essary tire wear. Check the tire pres-sures at least once a month.
o Be sure that the wheels are aligned
correctly. Improper alignment canresult from hitting curbs or driving too fast over irregular surfaces. Poor alignment causes faster tire wearand may also result in other prob- lems as well as greater fuel con- sumption.
o Keep your car in good condition. For better fuel economy and reducedmaintenance costs, maintain yourcar in accordance with the mainte- nance schedule in Section 5. If you drive your car in severe conditions,more frequent maintenance is re- quired (see Section 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 al-lowed to accumulate on the under- side of the car. This extra weight can result in increased fuel con-sumption and also contribute to cor- rosion.
o Travel lightly. Don't carry unneces- sary weight in your car. Weight re-duces fuel economy.
o Don't let the engine idle longer than necessary. If you are waiting (andnot in traffic), turn off your engine and restart only when you're readyto go.
o Remember, your Hyundai does not
require extended warm-up. As soonas the engine is running smoothly, you can drive away. In very cold weather, however, give your enginea slightly longer warm-up period.
o Don't "lug" or "over-rev" the engine.
Lugging is driving too slowly in toohigh a gear resulting in the engine bucking. If this happens, shift to a lower gear. Over-revving is racingthe engine beyond its safe limit. This can be avoided by shifting atthe recommended speeds.
o Use your air conditioning sparingly. The air conditioning system is oper-ated by engine power so your fueleconomy is reduced when you use it.

19SMOOTH CORNERINGWINTER DRIVING
C160A01A-AAT The more severe weather conditions of winter result in greater wear and other problems. To minimize the prob- lems of winter driving, you should fol-low these suggestions:
C150A01A-AAT Avoid braking or gear changing in cor- ners, especially when roads are wet. Ideally, corners should always be taken under gentle acceleration. If you followthese suggestions, tire wear will be held to a minimum. Also, apply the brake gently. It should be noted that installing tire chains onthe tire will provide a greater driving force, but will not prevent side skids. NOTE: Tire chains are not legal in all prov- inces. Check province laws before fitting tire chains.
C160B01A-GAT Snowy or Icy Conditions To drive your vehicle in deep snow, it may be necessary to use snow tires or to install tire chains on your tires. Ifsnow 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, suddenbrake applications, and sharp turns are potentially very hazardous prac- tices. During deceleration, use enginebraking to the fullest extent. Sudden brake applications on snowy or icy roads may cause skids to occur. Youneed to keep sufficient distance be- tween the vehicle in front and your vehicle. C160C01A-AAT Use High Quality Ethylene Glycol Coolant Your Hyundai is delivered with high quality ethylene glycol coolant in the cooling system. It is the only type of coolant that should be used because ithelps prevent corrosion in the cooling system, lubricates the water pump and prevents freezing. Be sure to replaceor replenish your coolant in accor- dance with the maintenance schedule in Section 5. Before winter, have yourcoolant tested to assure that its freez- ing point is sufficient for the tempera- tures anticipated during the winter.

C160H01A-AAT Use Approved Anti-Freeze in Window Washer System To keep the water in the window washer system from freezing, add an approvedanti-freeze solution in accordance with instructions on the container. Window washer anti-freeze is available fromHyundai dealers and most auto parts outlets. Do not use engine coolant or other types of anti-freeze as thesemay damage the finish.
C160G02A-GAT To Keep Locks from Freezing To keep the locks from freezing, squirt an approved de-icer fluid or glycerineinto the key opening. If a lock is cov- ered with ice, squirt it with an approved de-icing fluid to remove the ice. If thelock is frozen internally, you may be able to thaw it out by using a heated key. Handle the heated key with careto avoid injury. NOTE: The proper temperature for using the immobilizer key is from -40°C (- 40°F) to 80°C(176°F). If you heat the immobilizer key over 80°C to openthe frozen lock, it may cause dam- age to the transponder in its head.
C160D01A-AAT Check Battery and Cables Winter puts additional burdens on the battery system. Visually inspect thebattery and cables as described in Section 6. The level of charge in your battery can be checked by your Hyundaidealer or a service station. C160F01A-AAT Check Spark Plugs and Ignition System Inspect your spark plugs as described in Section 6 and replace them if neces-sary. Also check all ignition wiring and components to be sure they are not cracked, worn or damaged in any way.
C160E01A-AAT Change to "Winter Weight" Oil if Necessary In some climates it is recommended that a lower viscosity "winter weight" oil be used during cold weather. See Section 9 for recommendations. If youaren't sure what weight oil you should use, consult your Hyundai dealer.
