1- 44 FEATURES OF YOUR HYUNDAI
Your Hyundai is equipped with dual- diagonal braking systems. This means you still have braking on two wheelseven if one of the dual systems should fail. With only one of the dual systems working, more than normal pedal traveland greater pedal pressure are re- quired to stop the car. Also, the car will not stop in as short a distance with onlyhalf of the brake system working. If the brakes fail while you are driving, shift to a lower gear for additional enginebraking and stop the car as soon as it is safe to do so. B260J01A-GAT
CHARGING SYSTEM WARNING LIGHT
The charging system warning light should come on when the ignition isturned on, then go out when the engine
is running. If the light stays on while the engine is running, there is a malfunc-tion in the electrical charging system. If the light comes on while you are driv- ing, stop, turn off the engine and checkunder the hood. First, make certain the generator drive belt is in place. If it is, check the tension of the belt.

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 sideof 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 inan open area with the air intake set at "Fresh" and the fan operating at one of the higher speeds so fresh air is drawn into the interior. If you must drive with the trunk 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.!

C090H01L-GAT NOTE:
o For smooth and safe operation,
depress the brake pedal when shifting from "Neutral" positionor "Park" position to a forward or reverse gear.
o The ignition key must be in the "ON" position and the brake pedalfully depressed in order to move the shift lever from the "P" (Park)position to any of the other posi- tions.
o It is always possible to shift from "R", "N", "D" position to "P" po-sition. The vehicle must be fully stopped to avoid transaxle dam-age. C090I01L-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" or"D" 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 ignition when you leave the vehicle, even momentarily. Never leave the ve-hicle unattended while the en- gine is running.
o Check the automatic transaxle
fluid level regularly, and add fluidas necessary.
o See the maintenance schedule
for the proper fluid reco-mendation. C090N02O-AAT Good Driving Practices
o Never move the gear selector lever
from "P" or "N" to any other position with the accelerator pedal de- pressed.
o Never move the gear selector lever
into "P" when the vehicle is in mo-tion.
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 ex- tremely hazardous. Always leave the car in gear when moving.
o Do not "ride" the brakes. This can
cause them to overheat and mal-function. Instead, when you are driv- ing down a long hill, slow down andshift 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 maynot be engaged.
o Always use the parking brake. Do not depend on placing the transaxlein "P" to keep the car from moving.
o Exercise extreme caution when driv- ing on a slippery surface. Be espe-cially careful when braking, acceler-

If the indicator does not go out after three seconds after the engine has been started, have your car checkedby an authorized Hyundai dealer. NOTE:
1) When the TCS indicator illumi-
nates, traction control is auto- matically deactivated for safety.
2) This warning function is not pro-
vided when in the TCS-OFF mode.
3) When the engine starts, a click is
heard from the engine compart- ment; however, this is only thesound of traction control being checked.
4) When moving out of the mud or fresh snow, pressing the accel-erator pedal may not cause the engine speed to increase due toTCS operation.
C300D02L-GAT Indicator and Warning The TCS 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 or go out after three seconds, have it checked by an authorized dealer. Should there be any unusual condi- tions in the device, TCS illuminates asa 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. C130A01A-AAT GOOD BRAKING PRACTICES
WARNING:
Nothing should be carried on top of the cargo area cover behind therear seat. If there were an accident or a sudden stop, such objects could move forward and cause dam-age to the vehicle or injure the oc- cupants. 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 cause the car to pull to one side. To dry the brakes, apply the brakes lightly until the braking
action returns to normal, taking care to keep the car under control at all
times. If the braking action does notreturn to normal, stop as soon as it
is safe to do so and call your Hyundai dealer for assistance.
o Don't coast down hills with the car out of gear. This is extremely haz-ardous. Keep the car in gear at alltimes, use the brakes to slow down, then shift to a lower gear so that engine braking will help you main-tain a safe speed.

DRIVING YOUR HYUNDAI 2- 15
C150A01A-AAT SMOOTH CORNERING Avoid braking or gear changing in cor- ners, especially when roads are wet. Ideally, corners should always be takenunder gentle acceleration. If you follow these suggestions, tire wear will be held to a minimum.
o Don't "ride" the brake or clutch pedal.
This can increase fuel consumptionand also increase wear on thesecomponents. In addition, 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 con- sequences.
o Take care of your tires. Keep them inflated to the recommended pres-sure. Incorrect inflation, either toomuch 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 drivingtoo fast over irregular surfaces. Poor alignment causes faster tire wear and 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 your car 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 bekept clean and free of corrosivematerials. 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 ready to 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 engine a 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 enginebucking. If this happens, shift to a lower gear. Over-revving is racing the engine beyond its safe limit.This can be avoided by shifting at the recommended speeds.
o Use your air conditioning sparingly. The air conditioning system is oper-ated by engine power so your fuel economy is reduced when you useit.

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.
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. 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 Hyun-dai dealer or a service station. 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. SeeSection 9 for recommendations. If you aren't sure what weight oil you should use, consult your Hyundai dealer.
C160A01A-AAT WINTER DRIVING The more severe weather conditions of winter result in greater wear andother problems. To minimize the prob- lems of winter driving, you should fol- low these suggestions: 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. If snow tires are needed, it is necessaryto select tires equivalent in size and type of the original equipment tires. Failure to do so may adversely affectthe safety and handling of your car. Furthermore, speeding, rapid accel- eration, sudden brake applications, andsharp turns are potentially very haz- ardous practices. During deceleration, use engine brak-ing to the fullest extent. Sudden brake applications on snowy or icy roads may cause skids to occur. You need tokeep sufficient distance between the vehicle in front and your vehicle. Also, apply the brake gently. It should be noted that installing tire chains on the 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 beforefitting tire chains.
