2003 Hyundai Grandeur maintenance schedule

2- 10 DRIVING YOUR HYUNDAI
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-

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.

2- 16 DRIVING YOUR HYUNDAI
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.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
F060M01A-AAT
o Engine Oil and Filter
The engine oil and filter should be changed at the intervals specified in the maintenance schedule. If the car is being driven in severe conditions,more frequent oil and filter changes are required. F060B01A-AAT
o Drive Belts
Inspect all drive belts for evidence of cuts, cracks, excessive wear or oil and replace if necessary. Drive beltsshould be checked periodically for proper tension and adjusted as nec- essary. After installing a new filter, run the
engine for several minutes, and checkfor leaks at the connections. Fuelfilters should be installed by trained technicians.
F060D01A-AAT
o Fuel Lines, Fuel Hoses and Connections
Check the fuel lines, fuel hoses and connections for leakage and damage.Have a trained technician replace any damaged or leaking parts immedi- ately. F060E01A-AAT
o Timing Belt Inspect all parts related to the timing belt for damage and deformation. Replace any damaged parts immedi- ately. F060G01A-AAT
o Vapor Hose and Fuel Filler Cap The vapor hose and fuel filler cap should be inspected at those inter- vals specified in the maintenance schedule. Make sure that a new va-por hose or fuel filler cap is correctly replaced. F060F01A-AAT
o Vacuum, Crankcase Ventila-
tion Hoses
Inspect the surface of hoses for evi- dence of heat and/or mechanical dam-age. Hard and brittle rubber, crack- ing, tears, cuts, abrasions, and ex- cessive swelling indicate deteriora-tion. Particular attention should be paid to examine those hose surfaces nearest to high heat sources, such asthe exhaust manifold.Inspect the hose routing to assurethat the hoses do not come in contact with any heat source, sharp edges or moving component which might causeheat damage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make surethey are secure, and that no leaks are present. Hoses should be replaced immediately if there is any evidenceof deterioration or damage.
F060C01A-AAT
o Fuel Filter
A clogged filter can limit the speed atwhich the vehicle may be driven, dam- age the emission system and cause hard starting. If an excessive amountof foreign matter accumulates in the fuel tank, the filter may require re- placement more frequently.
