C140A01A-AAT DRIVING FOR ECONOMY You can save fuel and get more miles from your car if you follow these sug-gestions:
o Drive smoothly. Accelerate at a
moderate rate. Don't make "jack- rabbit" starts or full-throttle shifts and maintain a steady cruisingspeed. Don't race between stop- lights. Try to adjust your speed to that of the other traffic so you don'thave to change speeds unneces- sarily. Avoid heavy traffic whenever possible. Always maintain a safedistance from other vehicles so you can avoid unnecessary braking. This also reduces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel yourcar uses. Driving at a moderatespeed, especially on the highway, is one of the most effective ways to reduce fuel consumption.
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 park- ing brake can freeze in the engagedposition. This is most likely to hap-pen when there is an accumulation 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 tem- porarily while you put the gear se-lector lever in "P" (automatic) or in first or reverse gear (manual transaxle) and block the rear wheelsso the car cannot roll. Then release the parking brake.
o Do not hold the vehicle on the up- grade with the accelerator pedal.This can cause the transaxle to overheat. Always use the brakepedal or parking brake.
o Don't "ride" the brake pedal. Rest-
ing your foot on the brake pedalwhile driving can be dangerous be-cause it can result in the brakes
overheating and losing their effec- tiveness. It also increases the wearof the brake components.
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 besafe to do so, pull off the road and stop in a safe place.
o If your car is equipped with an auto- matic transaxle, don't let your carcreep forward. To avoid creeping forward, keep your foot firmly on the
brake pedal when the car is stopped.
o Use caution when parking on a hill.
Engage the parking brake and placethe gear selector lever in "P" (auto- matic transaxle) or in first or reverse
gear (manual transaxle). If your caris 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.

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.
