4- 2 CORROSION PREVENTION AND APPEARANCE CARE
E010A01A-AAT CORROSION PROTECTION Protecting Your Hyundai from Corro- sion:By using the most advanced design and construction practices to combat corrosion, Hyundai produces cars ofthe highest quality. However, this is only part of the job. To achieve the long-term corrosion resistance yourHyundai can deliver, the owner's co- operation and assistance is also re- quired. E010C01A-AAT High-Corrosion Areas If you live in an area where your car is regularly exposed to corrosive materi-als, corrosion protection is particularly important. Some of the common causes of accelerated corrosion areroad salts, dust control chemicals, ocean air and industrial pollution.
E010B01A-AAT Common Causes of Corrosion The most common causes of corro- sion on your car are:
o Road salt, dirt and moisture that is allowed to accumulate underneath the car.
o Removal of paint or protective coat- ings by stones, gravel, abrasion orminor scrapes and dents which leaveunprotected metal exposed to cor- rosion. E010D01A-AAT Moisture Breeds Corrosion Moisture creates the conditions in which corrosion is most likely to occur. For example, corrosion is accelerated by high humidity, particularly when tem-peratures are just above freezing. In such conditions, the corrosive mate- rial is kept in contact with the carsurfaces by moisture that is slow to evaporate. Mud is particularly corrosive becauseit is slow to dry and holds moisture in contact with the vehicle. Although themud appears to be dry, it can still retain the moisture and promote corrosion. High temperatures can also acceler-ate corrosion of parts that are not properly ventilated so the moisture can be dispersed. For all these rea-sons, it is particularly important to keep your car clean and free of mud or accumulations of other materials. Thisapplies not only to the visible surfaces but particularly to the underside of the car. E020A01A-AAT TO HELP PREVENT CORRO- SION You can help prevent corrosion from getting started by observing the follow- ing:

CORROSION PREVENTION AND APPEARANCE CARE 4- 3
E020C01A-AAT Keep Your Garage Dry Don't park your car in a damp, poorly ventilated garage. This creates a fa- vorable environment for corrosion. This is particularly true if you wash your carin the garage or drive it into the garage when it is still wet or covered with snow, ice or mud. Even a heated ga-rage can contribute to corrosion un- less it is well ventilated so moisture is dispersed. E020D02A-AAT Keep Paint and Trim in Good Condition Scratches or chips in the finish should be covered with "touch-up" paint as soon as possible to reduce the possi-bility of corrosion. If bare metal is show- ing through, the attention of a qualified body and paint shop is recommended. Bird droppings : Bird droppings are highly corrosive and may damagepainted surfaces in just a few hours. Always remove bird droppings as soon as possible. E020E01A-AAT Don't Neglect the Interior Moisture can collect under the floor mats and carpeting to cause corro-sion. Check under the mats periodi- cally to be sure the carpeting is dry. Use particular care if you carry fertiliz-ers, cleaning materials or chemicals in the car. These should be carried only in propercontainers and any spills or leaks should be cleaned up, flushed with clear water and thoroughly dried.
E020B01A-AAT Keep Your Car Clean The best way to prevent corrosion is to keep your car clean and free of corro-sive materials. Attention to the under- side of the car is particularly important.
o If you live in a high-corrosion area —
where road salts are used, near the ocean, areas with industrial pollu-tion, acid rain, etc.—, you should take extra care to prevent corro- sion. In winter, hose off the under-side of your car at least once a month and be sure to clean the underside thoroughly when winteris over.
o When cleaning underneath the car,
give particular attention to the com-ponents under the fenders and other areas that are hidden from view. Do a thorough job; just dampening theaccumulated mud rather than wash- ing it away will accelerate corrosion rather than prevent it. Water underhigh pressure and steam are par- ticularly effective in removing accu- mulated mud and corrosive materi-als. o When cleaning lower door panels,
rocker panels and frame members,be sure that drain holes are keptopen so that moisture can escape and not be trapped inside to ac- celerate corrosion.

auto parts outlet. Don't use strong household detergents, gasoline, strong solvents or abrasive cleaning powdersas these may damage the finish. Use a clean sponge or cloth, rinse it frequently and don't damage the finishby rubbing too hard. For stubborn spots, dampen them frequently and remove them a little at a time. To clean whitewall tires, use a stiff brush or soapy steel-wool scouringpad. To clean plastic wheel covers, use a clean sponge or soft cloth and water. To clean cast aluminum alloy wheels, use a mild soap or neutral detergent.Do not use abrasive cleaners. Protect the bare-metal surfaces by cleaning, polishing and waxing. Because alumi-num is subject to corrosion, be sure to give aluminum alloy wheels special attention in winter. If you drive onsalted roads, clean the wheels thor- oughly afterwards. After washing, be sure to rinse thor-oughly. If soapy water dries on the finish, streaking will result. When the weather is warm and the humidity low, you may find it neces-sary to rinse each section immediately after washing to avoid streaking. After rinsing, dry the car using a damp chamois or soft, absorbent cloth. The reason for drying the car is to removewater from the car so it will dry without water spots. Don't rub, this can dam- age the finish. If you find any nicks or scratches in the paint, use touch-up paint to coverthem to prevent corrosion. To protect the paintwork of the car against corro- sion, you must clean your Hyundai (atleast once a month). Give special at- tention to the removal of salt, mud and other substances on the underside ofthe splashboards of the car. Make sure that the outlets and the underside of the doors are open. Paint damagecan be caused by small accumulation of tar, industrial precipitation, tree resin, insects and bird droppings, when notremoved immediately. If water alone is
E030A01GK-AAT WASHING AND WAXING Washing Your Hyundai Never wash your car when the surface is hot from being in the sun. Always wash your car in the shade. Wash your car frequently. Dirt is abra- sive and can scratch the paint if it is notremoved. Air pollution or acid rain may damage the paint and trim through chemical action if pollutants are al-lowed to remain in contact with the surface. If you live near the ocean or in an area where road salts or dust con-trol chemicals are used, you should pay particular attention to the under- side of the car. Start by rinsing the carto remove dust and loose dirt. In win- ter, or if you have driven through mud or muddy water, be sure to thoroughlyclean the underside as well. Use a hard direct stream of water to remove accumulations of mud or corrosivematerials. High pressure car washes may cause water to enter your vehicle. Use a good quality car-washing solu-tion and follow the manufacturer's di- rections on the package. These are available at your Hyundai dealer or

E030D01A-AAT When to Wax Again You should polish and wax the car again when water no longer beads on a clean surface but spreads out over a larger area. E030E01A-AAT Maintaining Bumpers Special precautions must be observed to preserve the appearance of thebumpers on your Hyundai. They are:
o Be careful not to spill battery elec-
trolyte or hydraulic brake fluid on the bumpers. If you do, wash it off im- mediately with clear water.
E030B01A-AAT Spot Cleaning Don't use gasoline, strong solvents or corrosive cleaning agents. These can damage the finish of the car. To re- move road tar, use turpentine on a clean, soft cloth or commercially avail- able bug and tar remover. Be gentle.To remove dead insects or tree sap, use warm water and mild soap or car- washing solution. Soak the spot andrub gently. If the paint has lost its luster, use a commercial car-cleaning polish.
E030C01A-AAT Polishing and Waxing Always wash and dry the car before polishing or waxing or using a combi-nation cleaner and wax. Use a good quality commercial product and follow the manufacturer's directions on thecontainer. Polish and wax the bright trim pieces as well as the paint.
not strong enough to remove the accu-mulated dirt, use a mild car washing solution. Be sure to rinse the surfaceafter washing to remove the solution. Never allow the solution to dry on the painted surfaces.
E040A01A-AAT CLEANING THE INTERIOR To Clean the Vinyl Upholstery To clean the vinyl upholstery, first re- move loose dirt and dust with a vacuum cleaner. Then apply a solution of mild soap or detergent and water using aclean sponge or soft cloth. Allow this to stay on the surface to loosen the dirt, then wipe with a clean damp sponge orcloth. If all the dirt stains are not re- moved, repeat this procedure until the upholstery is clean. Do not use gaso-line, solvent, paint thinner or other strong cleaners.
o Be gentle when cleaning the bumper
surfaces. They are made of soft plastic and the surface can be dam-aged if mistreated. Do not use abra- sive cleaners. Use warm water and mild soap or car-washing solution.
o Do not expose the bumpers to high temperatures. For example, if youhave your car repainted, do notleave the bumpers on the car if the car is going to be placed in a high- temperature paint booth.

E040E01A-AAT Cleaning the Windows You may use any household window cleaner on the windows. However, when cleaning the inside of the rearwindow be careful not to damage the rear window defroster wiring. E050A01A-AAT Any Questions? If you have any questions about the care of your car, consult your Hyundaidealer.
E040D01A-AAT Cleaning the Seat Belts To clean the seat belts, use a cloth or sponge with mild soap or detergent and warm water. Do not use strongdetergents, dye, bleach or abrasive materials on the seat belts as this may weaken the fabric.
E040C01A-AAT Cleaning the Carpets Use a foam-type carpet cleaner. Clean- ers of this type are available in aerosolcans in liquid form or powder. Read the instructions and follow them exactly. Using a vacuum cleaner with the ap-propriate attachment, remove as much dirt from the carpets as possible. Apply the foam following the manufacturer'sdirections, then rub in overlapping circles. Do not add water. These clean- ers work best when the carpet is keptas dry as possible.
E040B01A-AAT To Clean the Leather Upholstery (If installed) In the normal course of use, leather upholstered surfaces will, like any material, pick-up dust and dirt. Thisdust and dirt must be cleaned off or it may work into the surface of the leather, causing damage. Fine leather needs care, and should be cleaned when necessary. Washingleather thoroughly with soap and water will keep your leather lustrous, beauti- ful and ensure you have many years ofwear. Take a piece of cheese cloth and using any mild soap and lukewarm water,work up a good lather. Thoroughly wash the leather. Wipe clean with a slightly damp cloth and dry with softcloth. Do this as often as the leather becomes soiled. During tanning operations, sufficient oils are incorporated through process- ing that none need be applied duringthe life of the leather. Oil applied to the finished surface will in no way help the leather and may do more harm than good. Varnishes and furniture polishes should never be used under any con- ditions.
While cleaning the belts, inspect them for excessive wear, cuts, fraying or other signs of damage and replacethem if necessary.
