DRIVING YOUR HYUNDAI 2- 9
resulting in the engine bucking. If this hap- pens, shift to a lower gear. Over-revving isracing the engine beyond its safe limit. Thiscan be avoided by shifting at the recom-mended speeds.
o Use your air conditioning sparingly. The air conditioning system is operated by enginepower so your fuel economy is reducedwhen you use it.

SMOOTH CORNERING Avoid braking or gear changing in corners,
especially when roads are wet. Ideally, cornersshould always be taken under gentle accelera-tion. If you follow these suggestions, tire wearwill be held to a minimum.
C160A01A-AAT
WINTER DRIVING The more severe weather conditions of winter
result in greater wear and other problems. Tominimize the problems of winter driving, youshould follow 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 tirechains on your tires. If snow tires are needed,
it is necessary to select tires equivalent in size
and type to the original equipment tires.
o Be sure that the wheels are aligned correct-
ly. Improper alignment can result from hittingcurbs or driving too fast over irregular sur-faces. Poor alignment causes faster tirewear and may also result in other problemsas well as greater fuel consumption.
o Keep your car in good condition. For better fuel economy and reduced maintenancecosts, maintain your car in accordance withthe maintenance schedule in Section 5. Ifyou drive your car in severe conditions,more frequent maintenance is required (seeSection 5 for details).
o Keep your car clean. For maximum service, your Hyundai should be kept clean and freeof corrosive materials. It is especially impor-tant that mud, dirt, ice, etc. not be allowed toaccumulate on the underside of the car. Thisextra weight can result in increased fuelconsumption and also contribute to corro-sion.
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 whenyou're ready to go.
o Remember, your Hyundai does not require extended warm-up. As soon as the engine isrunning smoothly, you can drive away. Invery cold weather, however, give your en-gine 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
C140A01A-AAT
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 cruisingspeed. Don't race between stoplights. Try toadjust your speed to that of the other trafficso you don't have to change speeds unnec-essarily. Avoid heavy traffic whenever pos-sible. Always maintain a safe distance fromother vehicles so you can avoid unneces-sary braking. This also reduces brake wear.
o Drive at a moderate speed. The faster you drive, the more fuel your car uses. Driving ata moderate speed, especially on the high-way, is one of the most effective ways toreduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This can increase fuel consumption and alsoincrease wear on these components. In ad-dition, driving with your foot resting on thebrake pedal may cause the brakes to over-heat, which reduces their effectiveness andmay lead to more serious consequences.
o Take care of your tires. Keep them inflated to the recommended pressure. Incorrect in-flation, either too much or too little, results inunnecessary tire wear. Check the tire pres-sures at least once a month.

MAINTENANCE INTERVALS Service requirements
To assure that you receive the greatest number
of kilometers of satisfying operation from your Hyundai, certain maintenance procedures must
be performed. Although careful design and en-
gineering have reduced these to a minimum,those that are required are of the utmost impor-tance.
It is your responsibility to have these mainte-
nance procedures performed to comply with theterms of the warranties covering your newHyundai. The Service Passport supplied withyour new vehicle provides further information
about these warranties. F010B01A-AAT
Maintenance Requirements The maintenance required for your Hyundai
can be divided into three main areas:
o Specified scheduled procedures
o General everyday checks
o Do-it-yourself maintenance F010C01A-GAT
Specified Scheduled Procedures
These are the procedures such as inspections,
adjustments and replacements that are listed in the maintenance charts starting on page 5-2.These procedures must be performed at theintervals shown in the maintenance schedule to
assure that your warranty remains in effect.Although it is strongly recommended that they
be performed by the factory-trained or distribu-tor-trained technicians at your Hyundai dealer,
these procedures may be performed at any
qualified service facility.
It is suggested that genuine Hyundai service
parts be used for any required repairs or re-placements. Other parts of equivalent quality
such as engine oil, engine coolant, manual orauto transaxle oil, brake fluid and so on which
are not supplied by Hyundai Motor Company or
its distributor may be used without affectingyour warranty coverage but you should always
be sure these are equivalent to the quality of theoriginal Hyundai parts. Your Service Passport
provides further information about your warran-ty coverage. F010E01A-AAT
Do-It-Yourself Maintenance
If you are mechanically inclined, own a few
tools that are required and want to take the timeto do so, you can inspect and service a number
of items. For more information about doing ityourself, see Section 6.
F010F01A-GAT
A Few Tips
o Whenever you have your Hyundai serviced, keep copies of the service records in your
glovebox. This will help ensure that you candocument that the required procedures have
been performed to keep your warranties ineffect. This is especially important when
service is not performed by an authorizedHyundai dealer.
F020A02X-GAT
SCHEDULED MAINTENANCE RE- QUIREMENTS Inspection should be performed any time a
malfunction is experienced or suspected. Re- ceipts for all emission control system services
should be retained to demonstrate compliancewith conditions of the emissions system war-ranty. For severe usage maintenance require-ments, see page 5-4 of this section.
F010D01A-AAT
General Checks These are the regular checks you should per-
form when you drive your Hyundai or you fill thefuel tank. A list of these items will be found onpage 6-2.

Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should be compatible with aluminum engine parts. Ad-ditional corrosion inhibitors or additives shouldnot be used. The cooling system must be main-tained with the correct concentration and typeof engine coolant to prevent freezing and corro-sion. Never allow the concentration of antifreeze to exceed the 60% level or go below the 35% levelor damage to the coolant system may result. Forproper concentration when adding or replacingthe coolant, refer to the following table.
35% 40%50%60% G050C01A-AAT
To Check the Coolant Level
The coolant level can be seen on the side of the plastic coolant reservoir. The level of the cool-ant should be between the "LOW" and "FULL"lines on the reservoir when the engine is cold.If the level is below the "LOW" mark, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect forcoolant leaks and recheck the fluid level fre-quently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason. G050D02A-AAT
To Change the Engine Coolant
The engine coolant should be changed at thoseintervals specified in the vehicle maintenanceschedule in Section 5. CAUTION: Engine coolant can damage the finish of your car. If you spill engine coolant on thecar, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking brake and remove the radiator cap whencool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the engine coolant to drain from thecooling system, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer's directions on the enginecoolant container, add the appropriate quan-tity of engine coolant to the radiator.

REPLACING THE SPARK PLUGS
The spark plugs should be changed at the
intervals specified in the vehicle maintenance schedule in Section 5 or whenever engine per-formance indicates they should be changed.Symptoms that suggest poor spark plug perfor-mance include engine misfiring under load, lossof fuel economy, poor acceleration, etc. Whenspark plugs are replaced, always use sparkplugs recommended by Hyundai. The use ofother spark plugs can result in loss of perfor-mance, radio interference or engine damage.
NOTE: When replacing the spark plug, always use
the genuine parts recommended.

5. Start the engine, top off the radiator with water and then add engine coolant to the reservoir until the level is between "LOW"and "FULL".
6. Replace the radiator and reservoir caps and check to be sure the drain cocks are fullyclosed and not leaking.
WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.Use extreme caution when working near theblades of the cooling fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition.
