TIRES AND WHEELS Tire care For proper maintenance, safety, and maximum fuel economy, you must always maintain recommended tire inflation pressures and stay within the load limits and weight distribution recommended for your vehicle.

Recommended cold tire inflation pressures All tire pressures (including the spare) should be checked when the tires are cold. “Cold Tires” means the vehicle has not been driven for at least three hours or driven less than one mile (1.6 km). Recommended pressures must be maintained for the best ride, vehicle handling, and minimum tire wear. For recommended inflation pressure, refer to “Tire and wheels” in section 8.

Maintenance

CAUTION

(cid:129) Underinflation also results in excessive wear,poor handling and reduced fuel economy. Wheel deformation also is possible.Keep your tire pres- sures at the proper levels.If a tire frequently needs refilling, have it checked by an author- ized HYUNDAI dealer.

(cid:129) Overinflation produces a harsh ride, excessive wear at the center of the tire tread,and a greater possibility of dam- age from road hazards.

OLM089008N All specifications (sizes and pres- sures) can be found on a label attached to the driver’s side center pillar.

WARNING - Tire underin-

flation

Severe underinflation can lead to severe heat build-up, causing blowouts, tread separation and other tire failures that can result in the loss of vehicle control leading to severe injury or death. This risk is much higher on hot days and when driving for long periods at high speeds.

7 37

CAUTION - Tire pressure Always observe the following: (cid:129) Check tire pressure when the tires are cold. (After vehicle has been parked for at least three hours or hasn't been driven more than one mile (1.6
km) since startup.)

(cid:129) Check the pressure of your spare tire each time you check the pressure of other tires.

(cid:129) Never overload your vehicle. Be careful not to overload a vehicle luggage rack if your vehicle is equipped with one. (cid:129) Worn,old tires can cause acci- dents. If your tread is badly worn, or if your tires have been damaged,replace them.

Checking tire inflation pressure Check your tires once a month or more. Also, check the tire pressure of the spare tire.

How to check Use a good quality gage to check tire pressure. You can not tell if your tires are properly inflated simply by look- ing at them. Radial tires may look properly inflated even when they're underinflated. Check the tire's inflation pressure when the tires are cold. - "Cold" means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km).

Maintenance

CAUTION

(cid:129) Warm tires normally exceed recommended cold tire pres- sures by 4 to 6 psi (28 to 41
kPa). Do not release air from warm tires to adjust the pres- sure or the tires will be under- inflated.

(cid:129) Be sure to reinstall the tire inflation valve caps. Without the valve cap,dirt or moisture could get into the valve core and cause air leakage. If a valve cap is missing,install a new one as soon as possible.

WARNING - Tire Inflation Overinflation or underinflation can reduce tire life, adversely affect vehicle handling, and lead to sudden tire failure. This could result in loss of vehicle control and potential injury.

38

Remove the valve cap from the tire valve stem. Press the tire gage firm- ly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the tire and loading information label, no further adjust- ment is necessary. If the pressure is low, add air until you reach the rec- ommended amount. If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. Recheck the tire pressure with the tire gage. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and mois- ture.

WARNING

(cid:129) Inspect your tires frequently for proper inflation as well as wear and damage. Always use a tire pressure gauge.

(cid:129) Tires with too much or too little pressure wear unevenly caus- ing poor handling, loss of vehi- cle control, and sudden tire failure leading to accidents, injuries, and even death. The recommended cold tire pres- sure for your vehicle can be found in this manual and on the tire label located on the dri- ver's side center pillar.

(cid:129) Worn tires can cause acci- dents. Replace tires that are worn, show uneven wear, or are damaged.

(cid:129) Remember to check the pres- sure of your spare tire. HYUNDAI recommends that you check the spare every time you check the pressure of the other tires on your vehi- cle.

Maintenance

Tire rotation To equalize tread wear, it is recom- mended that the tires be rotated every 7,500 miles (12,000 km) or sooner if irregular wear develops. During rotation, check the tires for correct balance. When rotating tires, check for uneven wear and damage. Abnormal wear is usually caused by incorrect tire pres- sure, improper wheel alignment, out- of-balance wheels, severe braking or severe cornering. Look for bumps or bulges in the tread or side of tire. Replace the tire if you find either of these conditions. Replace the tire if fabric or cord is visible. After rotation, be sure to bring the front and rear tire pressures to specification and check lug nut tightness. Refer to “Tire and wheels” in section 8.

7 39

Maintenance

Without a spare tire

Directional tires (if equipped)

S2BLA790A

Disc brake pads should be inspected for wear whenever tires are rotated.

✽✽ NOTICE Rotate radial tires that have an asymmetric tread pattern only from front to rear and not from right to left.

WARNING

(cid:129) Do not use the compact spare

tire for tire rotation.

(cid:129) Do not mix bias ply and radial ply tires under any circum- stances. This may cause unusual handling characteris- tics that could result in death, severe injury, or property damage.

CBGQ0707A

40

Wheel alignment and tire balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. In most cases, you will not need to have your wheels aligned again. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced.

CAUTION

Improper wheel weights can damage your vehicle's alu- minum wheels. Use only approved wheel weights.

Tread wear indicator

OEN076053

Tire replacement If the tire is worn evenly, a tread wear indicator will appear as a solid band across the tread. This shows there is less than 1/16 inch (1.6 mm) of tread left on the tire. Replace the tire when this happens. Do not wait for the band to appear across the entire tread before replac- ing the tire.

WARNING - Replacing

tires

To reduce the chance or serious or fatal injuries from an acci- dent caused by tire failure or loss of vehicle control: (cid:129) Replace tires that are worn, show uneven wear, or are damaged. Worn tires can cause loss of braking effec- tiveness, steering control, and traction.

(cid:129) Do not drive your vehicle with too little or too much pressure in your tires. This can lead to uneven wear and tire failure.

(cid:129) When replacing tires, never mix radial and bias-ply tires on the same car. You must replace all tires (including the spare) if moving from radial to bias-ply tires.

(Continued)

Maintenance

(Continued) (cid:129) Using tires and wheel other than the recommended sizes could cause unusual handling characteristics and poor vehi- cle control, resulting in a seri- ous accident.

(cid:129) Wheels that do not meet HYUNDAI’s specifications may fit poorly and result in damage to the vehicle or unusual han- dling and poor vehicle control. (cid:129) The ABS works by comparing the speed of the wheels. Tire size can affect wheel speed. When replacing tires, all 4
tires must use the same size originally supplied with the vehicle. Using tires of a differ- ent size can cause the ABS (Anti-lock Brake System) and ESC (Electronic Stability Control) to work irregularly (if equipped).

7 41

Maintenance

Compact spare tire replacement A compact spare tire has a shorter tread life than a regular size tire. Replace it when you can see the tread wear indicator bars on the tire. The replacement compact spare tire should be the same size and design tire as the one provided with your new vehicle and should be mounted on the same compact spare tire wheel. The compact spare tire is not designed to be mounted on a regular size wheel, and the compact spare tire wheel is not designed for mount- ing a regular size tire.

42

Wheel replacement When replacing the metal wheels for any reason, make sure the new wheels are equivalent to the original factory units in diameter, rim width and offset.

WARNING

A wheel that is not the correct size may adversely affect wheel and bearing life, braking and stopping abilities, handling characteristics, ground clear- ance, body-to-tire clearance, snow clearance, speedometer and odometer cal- ibration, headlight aim and bumper height.

chain

Tire traction Tire traction can be reduced if you drive on worn tires, tires that are improperly inflated or on slippery road surfaces. Tires should be replaced when tread wear indicators appear. Slow down whenever there is rain, snow or ice on the road to reduce the possibility of losing con- trol of the vehicle.

Tire maintenance In addition to proper inflation, correct wheel alignment helps to decrease tire wear. If you find a tire is worn unevenly, have your dealer check the wheel alignment. When you have new tires installed, make sure they are balanced. This will increase vehicle ride comfort and tire life. Additionally, a tire should always be rebalanced if it is removed from the wheel.

information

Tire sidewall labeling This identifies and describes the fundamental charac- teristics of the tire and also provides the tire identification number (TIN) for safety standard certification. The TIN can be used to identify the tire in case of a recall.

1.Manufacturer or brand name Manufacturer or Brand name is shown.

2.Tire size designation A tire’s sidewall is marked with a tire size designation. You will need this information when selecting replace- ment tires for your car. The following explains what the letters and num- bers in the tire size designation mean. Example tire size designation: (These numbers are provided as an example only; your tire size designa- tor could vary depending on your vehicle.) 225/55R18 105T

225 - Tire width in millimeters. 55 - Aspect ratio. The tire’s section height as a percentage of its width.

R - Tire construction code (Radial). 18 - Rim diameter in inches. 105 - Load Index, a numerical code associated with the maximum load the tire can carry.

T - Speed Rating Symbol. See the speed rating chart in this section for additional information.

Maintenance

Wheel size designation Wheels are also marked with impor- tant information that you need if you ever have to replace one. The follow- ing explains what the letters and numbers in the wheel size designa- tion mean.

Example wheel size designation: 6.5JX18

6.5 - Rim width in inches. J - Rim contour designation. 18 - Rim diameter in inches.

3.Checking tire life (TIN :Tire

Identification Number)

Any tires that are over 6 years old, based on the manufacturing date, (including the spare tire) should be replaced by new ones. You can find the manufacturing date on the tire sidewall (possibly on the inside of the wheel), displaying the DOT Code. The DOT Code is a series of num- bers on a tire consisting of numbers and English letters. The manufactur- ing date is designated by the last four digits (characters) of the DOT code.

DOT : XXXX XXXX OOOO The front part of the DOT means a plant code number, tire size and tread pattern and the last four num- bers indicate week and year manu- factured. For example: DOT XXXX XXXX 1610 represents that the tire was produced in the 16th week of 2010.

WARNING - Tire age

Tires degrade over time, even when they are not being used. Regardless of the remaining tread, it is recommended that tires generally be replaced after six (6) years of normal service. Heat caused by hot climates or frequent high loading condi- tions can accelerate the aging process. Failure to follow this warning can result in sudden tire failure, which could lead to a loss of control and an acci- dent involving serious injury or death.

4.Tire ply composition and material The number of layers or plies of rub- ber-coated fabric in the tire. Tire manufacturers also must indicate the materials in the tire, which include steel, nylon, polyester, and others. The letter "R" means radial ply con- struction; the letter "D" means diago- nal or bias ply construction; and the letter "B" means belted-bias ply con- struction.

5.Maximum permissible inflation

pressure

This number is the greatest amount of air pressure that should be put in the tire. Do not exceed the maximum permissible inflation pressure. Refer to the Tire and Loading Information label inflation pressure.

for recommended

6.Maximum load rating This number indicates the maximum load in kilograms and pounds that can be carried by the tire. When replacing the tires on the vehicle, always use a tire that has the same load rating as the factory installed tire.

the

7.Uniform tire quality grading Quality grades can be found where applicable on tire sidewall between tread shoulder and maxi- mum section width. For example: TREAD wear 200 TRACTION AA TEMPERATURE A

Tread wear The tread wear grade is a compara- tive rating based on the wear rate of the tire when tested under controlled conditions on a specified govern- ment test course. For example, a tire graded 150 would wear one-and-a- half times (1½) as well on the gov- ernment course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. These grades are molded on the side-walls of passenger vehicle tires.

Maintenance

The tires available as standard or optional equipment on your vehicle may vary with respect to grade.

Traction - AA, A, B & C The traction grades, from highest to lowest, are AA, A, B and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on spec- ified government test surfaces of asphalt and concrete. A tire marked C may have poor traction perform- ance.

WARNING

The traction grade assigned to this tire is based on straight- ahead braking traction tests, and does not include accelera- tion, cornering, hydroplaning, or peak traction characteristics.

7 45

Maintenance

Temperature -A, B & C The temperature grades are A (the highest), B and C representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled condi- tions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C cor- responds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the labora- tory test wheel than the minimum required by law.

46

WARNING - Tire

temperature

The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat build-up and possible sudden tire failure. This can cause loss of vehicle control and serious injury or death.

Tire terminology and definitions Air Pressure: The amount of air inside the tire pressing outward on the tire. Air pressure is expressed in pounds per square inch (psi) or kilo- pascal (kPa). Accessory Weight: This means the combined weight of optional acces- sories. Some examples of optional accessories are, automatic transaxle, power seats, and air conditioning. Aspect Ratio: The relationship of a tire's height to its width. Belt: A rubber coated layer of cords that is located between the plies and the tread. Cords may be made from steel or other reinforcing materials. Bead: The tire bead contains steel wires wrapped by steel cords that hold the tire onto the rim. Bias Ply Tire: A pneumatic tire in which the plies are laid at alternate angles less than 90 degrees to the centerline of the tread.

Cold Tire Pressure: The amount of air pressure in a tire, measured in pounds per square inch (psi) or kilo- pascals (kPa) before a tire has built up heat from driving. Curb Weight: This means the weight of a motor vehicle with standard and optional equipment including the maximum capacity of fuel, oil and coolant, but without passengers and cargo. DOT Markings: A code molded into the sidewall of a tire signifying that the tire is in compliance with the U.S. Department of Transportation motor vehicle safety standards. The DOT code includes the Tire Identification Number (TIN), an alphanumeric des- ignator which can also identify the tire manufacturer, production plant, brand and date of production. GVWR: Gross Vehicle Weight Rating GAWR FRT: Gross Axle Weight Rating for the Front Axle. GAWR RR: Gross Axle Weight Rating for the Rear axle.

Intended Outboard Sidewall: The side of an asymmetrical tire, that must always face outward when mounted on a vehicle. Kilopascal (kPa): The metric unit for air pressure. Load Index: An assigned number ranging from 1 to 279 that corre- sponds to the load carrying capacity of a tire. Maximum Inflation Pressure: The maximum air pressure to which a cold tire may be inflated. The maxi- mum air pressure is molded onto the sidewall. Maximum Load Rating: The load rating for a tire at the maximum per- missible inflation pressure for that tire. Maximum Loaded Vehicle Weight: The sum of curb weight; accessory weight; vehicle capacity weight; and production options weight. Normal Occupant Weight: The number of occupants a vehicle is designed to seat multiplied by 150
pounds (68 kg).

Maintenance

7 47

Maintenance

Speed Rating: An alphanumeric code assigned to a tire indicating the maximum speed at which a tire can operate. Traction: The friction between the tire and the road surface. The amount of grip provided. Tread: The portion of a tire that comes into contact with the road. Treadwear Indicators: Narrow bands, sometimes called "wear bars," that show across the tread of a tire when only 2/32 inch of tread remains. UTQGS: Uniform Tire Quality Grading Standards, a tire information system that provides consumers with ratings for a tire's traction, tempera- ture and treadwear. Ratings are determined by tire manufacturers using government testing proce- dures. The ratings are molded into the sidewall of the tire. Vehicle Capacity Weight: The num- ber of designated seating positions multiplied by 150 lbs. (68 kg) plus the rated cargo and luggage load.

Vehicle Maximum Load on the Tire: Load on an individual tire due to curb and accessory weight plus maximum occupant and cargo weight. Vehicle Normal Load on the Tire: Load on an individual tire that is determined by distributing to each axle its share of the curb weight, accessory weight, and normal occu- pant weight and dividing by 2. Vehicle Placard: A label permanent- ly attached to a vehicle showing the original equipment tire size and rec- ommended inflation pressure.

All season tires HYUNDAI specifies all season tires on some models to provide good performance for use all year round, including snowy and icy road condi- tions. All season tires are identified by ALL SEASON and/or M+S (Mud and Snow) on the tire sidewall. Snow tires have better snow traction than all season tires and may be more appropriate in some areas.

Summer tires HYUNDAI specifies summer tires on some models to provide superior performance on dry roads. Summer tire performance is substantially reduced in snow and ice. Summer tires do not have the tire traction rat- ing M+S (Mud and Snow) on the tire side wall. if you plan to operate your vehicle in snowy or icy conditions. HYUNDAI recommends the use of snow tires or all season tires on all four wheels.

Snow tires If you equip your car with snow tires, they should be the same size and have the same load capacity as the original tires. Snow tires should be installed on all four wheels; other- wise, poor handling may result. Snow tires should carry 4 psi (28
kPa) more air pressure than the pressure recommended for the stan- dard tires on the tire label on the dri- ver's side of the center pillar, or up to the maximum pressure shown on the tire sidewall, whichever is less.

48

Do not drive faster than 75 mph (120
km/h) when your vehicle is equipped with snow tires.

Tire chains Tire chains, if necessary, should be installed on the drive wheels as fol- lows. 2WD : Front wheels AWD : All four wheels

If a full set of chains is not available for a AWD vehicle, chains may be installed on the front wheels only.

Be sure that the chains are installed in accordance with the manufactur- er's instructions. To minimize tire and chain wear, do not continue to use tire chains when they are no longer needed.

WARNING - Snow or ice

(cid:129) When driving on roads cov- ered with snow or ice, drive at less than 20 mph (30 km/h).

(cid:129) Use the SAE “S” class or wire

chains.

(cid:129) If you hear noise caused by chains contacting the body, retighten the chain to avoid contact with the vehicle body. (cid:129) To prevent body damage, retighten the chains after driv- ing 0.3~0.6 miles (0.5~1.0 km). (cid:129) Do not use tire chains on vehicles equipped with alu- minum wheels. In unavoid- able circumstance, use a wire type chain.

(cid:129) Use wire chains less than 0.59
inches (15 mm) to prevent damage to the chain’s con- nection.

Maintenance

Radial-ply tires Radial-ply tires provide improved tread life, road hazard resistance and smoother high speed ride. The radi- al-ply tires used on this vehicle are of belted construction, and are selected to complement the ride and handling characteristics of your vehicle. Radial-ply tires have the same load carrying capacity, as bias-ply or bias belted tires of the same size, and use the same recommended inflation pressure. Mixing of radial-ply tires with bias-ply or bias belted tires is not recommended. Any combina- tions of radial-ply and bias-ply or bias belted tires when used on the same vehicle will seriously deteriorate vehicle handling. The best rule to fol- low is: Identical radial-ply tires should always be used as a set of four. Longer wearing tires can be more susceptible to irregular tread wear. It is very important to follow the tire rotation interval shown in this section to achieve the tread life potential of these tires. Cuts and punctures in radial-ply tires are repairable only in the tread area, because of sidewall flexing. Consult your tire dealer for radial-ply tire repairs.

7 49

A vehicle’s electrical system is protected from electrical overload damage by fuses. This vehicle has 3 fuse panels, one locat- ed in the driver’s side panel bolster, the other in the engine compartment. If any of your vehicle’s lights, acces- sories, or controls do not work, check the appropriate circuit fuse. If a fuse has blown, the element inside the fuse will melt. If the electrical system does not work, first check the driver’s side fuse panel. Always replace a blown fuse with one of the same rating. If the replacement fuse blows, this indi- cates an electrical problem. Avoid using the system involved and immediately consult an authorized HYUNDAI dealer. Four kinds of fuse are used:blade type, cartridge type, multi fuse and main fuse.

WARNING - Fuse replace-

ment

(cid:129) Never replace a fuse with any- thing but another fuse of the same rating.

(cid:129) A higher capacity fuse could cause damage and possibly a fire.

(cid:129) Never install a wire instead of the proper fuse - even as a temporary repair. It may cause extensive wiring damage and a possible fire.

CAUTION

Do not use a screwdriver or any other metal object to remove fuses because it may cause a short circuit and damage the system.

LIGHT BULBS

WARNING - Working on

the lights

Prior to working on the light, firmly apply the parking brake, ensure that the ignition switch is turned to the LOCK position and turn off the lights to avoid sudden movement of the vehicle and burning your fin- gers or receiving an electric shock.

Use only the bulbs of the specified wattage.

CAUTION

Be sure to replace the burned-out bulb with one of the same wattage rating. Otherwise, it may cause damage to the fuse or electric wiring system.

CAUTION

If you don’t have necessary tools, the correct bulbs and the expertise, consult an authorized HYUNDAI dealer.In many cases,it is difficult to replace vehicle light bulbs because other parts of the vehicle must be removed before you can get to the bulb. This is especially true if you have to remove the head- light assembly to get to the bulb(s). Removing/installing the headlight assembly can result in damage to the vehicle.

✽✽ NOTICE After heavy, driving rain or washing, headlight and taillight lenses could appear frosty. This condition is caused by the temperature difference between the lamp inside and outside. This is similar to the condensation on your windows inside your vehicle during the rain and doesn’t indicate a problem with your vehicle. If the water leaks into the lamp bulb circuitry, have the vehicle checked by an authorized HYUNDAI dealer.

WARNING - Wet brakes

After washing the vehicle, test the brakes while driving slowly to see if they have been affected by water. If braking performance is impaired, dry the brakes by applying them lightly while maintaining a slow for- ward speed.

Even prompt washing with plain water may not completely remove all these deposits. A mild soap, safe for use on painted surfaces, may be used. After washing, rinse the vehicle thor- oughly with lukewarm or cold water. Do not allow soap to dry on the finish.

CAUTION

(cid:129) Do not use strong soap,chemical detergents or hot water, and do not wash the vehicle in direct sunlight or when the body of the vehicle is warm.

(cid:129) Be careful when washing the side

windows of your vehicle. Especially, with high-pressure water.Water may leak through the windows and wet the interior.

(cid:129) To prevent damage to the plastic parts,do not clean with chemical solvents or strong detergents.

Maintenance

APPEARANCE CARE Exterior care Exterior general caution It is very important to follow the label directions when using any chemical cleaner or polish. Read all warning and caution statements that appear on the label.

Finish maintenance Washing To help protect your vehicle’s finish from rust and deterioration, wash it thoroughly and frequently at least once a month with lukewarm or cold water. If you use your vehicle for off-road driv- ing, you should wash it after each off- road trip. Pay special attention to the removal of any accumulation of salt, dirt, mud, and other foreign materials. Make sure the drain holes in the lower edges of the doors and rocker panels are kept clear and clean. Insects, tar, tree sap, bird droppings, industrial pollution and similar deposits can damage your vehicle’s finish if not removed immediately.

66

Waxing A good coat of wax is a barrier between your paint and contaminate. Keeping a good coat of wax on your vehicle will help protect it. Wax the vehicle when water will no longer bead on the paint. Always wash and dry the vehicle before waxing. Use a good quality liquid or paste wax, and follow the manufacturer’s instructions. Wax all metal trim to protect it and to maintain its luster. Removing oil, tar, and similar materials with a spot remover will usually strip the wax from the finish. Be sure to re-wax these areas even if the rest of the vehicle does not yet need waxing.

CAUTION

(cid:129) Wiping dust or dirt off the body with a dry cloth will scratch the finish.

(cid:129) Do not use steel wool, abrasive cleaners, or strong detergents containing highly alkaline or caustic agents on chrome-plated or anodized aluminum parts.This may result in damage to the pro- tective coating and cause discol- oration or paint deterioration.

OJB037800

CAUTION

(cid:129) Water washing in the engine com- partment including high pressure water washing may cause the fail- ure of electrical circuits located in the engine compartment.

(cid:129) Never allow water or other liquids to come in contact with electri- cal/electronic components inside the vehicle as this may damage them.

Maintenance

Finish damage repair Deep scratches or stone chips in the painted surface must be repaired promptly. Exposed metal will quickly rust and may develop into a major repair expense.

✽✽ NOTICE If your vehicle is damaged and requires any metal repair or replacement, be sure the body shop applies anti-corrosion materials to the parts repaired or replaced.

7 67

Maintenance

Bright-metal maintenance (cid:129) To remove road tar and insects, use a tar remover, not a scraper or other sharp object.

(cid:129) To protect the surfaces of bright-metal parts from corrosion, apply a coating of wax or chrome preservative and rub to a high luster.

(cid:129) During winter weather or in coastal areas, cover the bright metal parts with a heavier coating of wax or preserva- tive. If necessary, coat the parts with non-corrosive petroleum jelly or other protective compound.

68

Aluminum wheel maintenance The aluminum wheels are coated with a clear protective finish. (cid:129) Do not use any abrasive cleaner, pol- ishing compound, solvent, or wire brushes on aluminum wheels. They may scratch or damage the finish.

(cid:129) Use only a mild soap or neutral deter- gent, and rinse thoroughly with water. Also, be sure to clean the wheels after driving on salted roads. This helps pre- vent corrosion.

(cid:129) Avoid washing the wheels with high-

speed car wash brushes.

(cid:129) Do not use any cleaners containing acid or acid detergents. It may damage and corrode the aluminum wheels coated with a clear protective finish.

Underbody maintenance Corrosive materials used for ice and snow removal and dust control may col- lect on the underbody. If these materials are not removed, accelerated rusting can occur on underbody parts such as the fuel lines, frame, floor pan and exhaust system, even though they have been treated with rust protection. Thoroughly flush the vehicle underbody and wheel openings with lukewarm or cold water once a month, after off-road driving and at the end of each winter. Pay special attention to these areas because it is difficult to see all the mud and dirt. It will do more harm than good to wet down the road grime without removing it. The lower edges of doors, rocker panels, and frame members have drain holes that should not be allowed to clog with dirt; trapped water in these areas can cause rusting.

WARNING

After washing the vehicle, test the brakes while driving slowly to see if they have been affected by water. If braking performance is impaired, dry the brakes by applying them lightly while maintaining a slow for- ward speed.

High-corrosion areas If you live in an area where your vehicle is regularly exposed to corrosive materi- als, corrosion protection is particularly important. Some of the common causes of accelerated corrosion are road salts, dust control chemicals, ocean air and industrial pollution.

Corrosion protection Protecting your vehicle from corrosion By using the most advanced design and construction practices to combat corro- sion, we produces cars of the highest quality. However, this is only part of the job. To achieve the long-term corrosion resistance your vehicle can deliver, the owner's cooperation and assistance is also required.

Common causes of corrosion The most common causes of corrosion on your car are: (cid:129) Road salt, dirt and moisture that is allowed to accumulate underneath the vehicle.

(cid:129) Removal of paint or protective coatings by stones, gravel, abrasion or minor scrapes and dents which leave unpro- tected metal exposed to corrosion.

Maintenance

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 tempera- tures are just above freezing. In such conditions, the corrosive material is kept in contact with the car surfaces by mois- ture that is slow to evaporate. Mud is particularly corrosive because it is slow to dry and holds moisture in contact with the vehicle. Although the mud appears to be dry, it can still retain the moisture and promote corrosion. High temperatures can also accelerate corrosion of parts that are not properly ventilated so the moisture can be dis- persed. For all these reasons, it is par- ticularly important to keep your vehicle clean and free of mud or accumulations of other materials. This applies not only to the visible surfaces but particularly to the underside of the vehicle.

7 69

Maintenance

To help prevent corrosion You can help prevent corrosion from get- ting started by observing the following:

Keep your car clean The best way to prevent corrosion is to keep your vehicle clean and free of cor- rosive materials. Attention to the under- side of the vehicle is particularly impor- tant.

(cid:129) If you live in a high-corrosion area — where road salts are used, near the ocean, areas with industrial pollution, acid rain, etc.—, you should take extra care to prevent corrosion. In winter, hose off the underside of your vehicle at least once a month and be sure to clean the underside thoroughly when winter is over.

70

(cid:129) When cleaning underneath the vehicle, give particular attention to the compo- nents under the fenders and other areas that are hidden from view. Do a thorough job; just dampening the accu- mulated mud rather than washing it away will accelerate corrosion rather than prevent it. Water under high pres- sure and steam are particularly effec- tive in removing accumulated mud and corrosive materials.

(cid:129) When cleaning lower door panels, rocker panels and frame members, be sure that drain holes are kept open so that moisture can escape and not be trapped inside to accelerate corrosion.

Keep your garage dry Don't park your car in a damp, poorly ventilated garage. This creates a favor- able environment for corrosion. This is particularly true if you wash your vehicle in the garage or drive it into the garage when it is still wet or covered with snow, ice or mud. Even a heated garage can contribute to corrosion unless it is well ventilated so moisture is dispersed.

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 possibility of cor- rosion. If bare metal is showing through, the attention of a qualified body and paint shop is recommended.

Bird droppings : Bird droppings are high- ly corrosive and may damage painted surfaces in just a few hours. Always remove bird droppings as soon as possi- ble.

Don't neglect the interior Moisture can collect under the floor mats and carpeting to cause corrosion. Check under the mats periodically to be sure the carpeting is dry. Use particular care if you carry fertilizers, cleaning materials or chemicals in the vehicle. These should be carried only in proper containers and any spills or leaks should be cleaned up, flushed with clean water
