at a NISSAN dealer or any automotive accessory store. UNDERBODY In areas where road salt is used in winter, it is necessary to clean the underbody regularly in order to prevent dirt and salt from building up and causing the acceleration of corrosion on the un- derbody and suspension. Before the winter pe- riod and again in the spring, the underseal must be checked and, if necessary, retreated.


Use glass cleaner to remove smoke and dust film from the glass surfaces. It is normal for glass to become coated with a film after the vehicle is parked in the hot sun. Glass cleaner and a soft cloth will easily remove this film.


CAUTION


When cleaning the inside of the windows, do not use sharp-edged tools, abrasive cleaners or chlorine-based disinfectant cleaners. They could damage the electri- cal conductors, radio antenna elements or rear window defroster elements.


ALUMINUM ALLOY WHEELS Wash the wheels regularly with a sponge damp- ened in a mild soap solution, especially during winter months in areas where road salt is used. If not removed, road salt can discolor the wheels.


CAUTION


Follow the directions below to avoid staining or discoloring the wheels: c Do not use a cleaner that uses strong acid or alkali contents to clean the wheels.

c Wipe off excess tire dressing using a dry towel. Make sure the tire dressing is com- pletely removed from the tire tread/grooves. c Allow the tire dressing to dry as recom-


mended by tire dressing manufacturer.


CLEANING INTERIOR


Occasionally remove loose dust from the interior trim, plastic parts and seats using a vacuum cleaner or soft bristled brush. Wipe the vinyl and leather surfaces with a clean, soft cloth damp- ened in mild soap solution, then wipe clean with a dry, soft cloth.


Regular care and cleaning is required in order to maintain the appearance of the leather.


Before using any fabric protector, read the manu- facturer(cid:146)s recommendations. Some fabric pro- tectors contain chemicals that may stain or bleach the seat material.


Use a cloth dampened only with water to clean the meter and gauge lens.


CAUTION


c Do not use water or acidic cleaners (hot steam cleaners) on the seat. This can damage the seat or occupant classifica- tion sensor. This can also affect the operation of the air bag system and result in serious personal injury.


c Never use benzine, thinner or any simi-


lar material.


c Do not apply wheel cleaners to the wheels when they are hot. The wheel temperature should be the same as am- bient temperature.


c Rinse the wheel to completely remove the cleaner within 15 minutes after the cleaner is applied. CHROME PARTS Clean all chrome parts regularly with a non- abrasive chrome polish to maintain the finish. TIRE DRESSINGS NISSAN does not recommend the use of tire dressings. Tire manufacturers apply a coating to the tires to help reduce discoloration of the rub- ber. If a tire dressing is applied to the tires, it may react with the coating and form a compound. This compound may come off the tire while driving and stain the vehicle paint. If you choose to use a tire dressing, take the following precautions: c Use a water-based tire dressing. The coat- ing on the tire dissolves more easily with an oil-based tire dressing.

SEAT BELTS The seat belts can be cleaned by wiping them with a sponge dampened in a mild soap solution. Allow the belts to dry completely in the shade before using them. See (cid:147)Seat belt maintenance(cid:148) in the (cid:147)Safety (cid:150) Seats, seat belts and supplemen- tal restraint system(cid:148) section of this manual.


WARNING


Do not allow wet seat belts to roll up in the retractor. NEVER use bleach, dye or chemical solvents to clean the seat belts, since these materials may severely weaken the seat belt webbing.


c Small dirt particles can be abrasive and damaging to leather surfaces and should be removed promptly. Do not use saddle soap, car waxes, polishes, oils, cleaning fluids, solvents, deter- gents or ammonia-based cleaners as they may damage the leather(cid:146)s natural finish.


c Never use fabric protectors unless rec-


ommended by the manufacturer.


c Do not use glass or plastic cleaner on meter or gauge lens covers. It may dam- age the lens cover.


FLOOR MATS The use of genuine NISSAN floor mats can ex- tend the life of your vehicle carpet and make it easier to clean the interior. No matter what mats are used, be sure they are fitted for your vehicle and are properly positioned in the footwell to prevent interference with pedal operation. Mats should be maintained with regular cleaning and replaced if they be- come excessively worn.


WAI0006
Floor mat positioning aid (driver(cid:146)s side only) This vehicle includes a front floor mat bracket to act as a floor mat positioning aid. NISSAN floor mats have been specially designed for your ve- hicle model. The driver(cid:146)s side floor mat has a grommet hole incorporated in it. Position the mat by placing the floor mat bracket hook through the floor mat grommet hole while centering the mat in the footwell. Periodically check to make certain the mats are properly positioned.

CORROSION PROTECTION


MOST COMMON FACTORS CONTRIBUTING TO VEHICLE CORROSION c The accumulation of moisture-retaining dirt and debris in body panel sections, cavities, and other areas.


c Damage to paint and other protective coat- ings caused by gravel and stone chips or minor traffic accidents.


ENVIRONMENTAL FACTORS INFLUENCE THE RATE OF CORROSION Moisture Accumulation of sand, dirt and water on the ve- hicle body underside can accelerate corrosion. Wet floor coverings will not dry completely inside the vehicle, and should be removed for drying to avoid floor panel corrosion. Relative humidity Corrosion will be accelerated in areas of high relative humidity, especially those areas where the temperatures stay above freezing and where atmospheric pollution exists and road salt is used.


7-6 Appearance and care


Temperature High temperatures accelerate the rate of corro- sion to those parts which are not well ventilated. Air pollution Industrial pollution, the presence of salt in the air in coastal areas, or heavy road salt use acceler- ates the corrosion process. Road salt also accel- erates the disintegration of paint surfaces. TO PROTECT YOUR VEHICLE FROM CORROSION c Wash and wax your vehicle often to keep the


vehicle clean.


c Always check for minor damage to the paint


and repair it as soon as possible.


c Keep drain holes at the bottom of the doors


open to avoid water accumulation.


c Check the underbody for accumulation of sand, dirt or salt. If present, wash with water as soon as possible.


CAUTION


c NEVER remove dirt, sand or other de- bris from the passenger compartment by washing it out with a hose. Remove dirt with a vacuum cleaner or broom.


c Never allow water or other liquids to come in contact with electronic compo- nents inside the vehicle as this may damage them.


Chemicals used for road surface de-icing are extremely corrosive. They accelerate corrosion and deterioration of underbody components such as the exhaust system, fuel and brake lines, brake cables, floor pan and fenders. In winter, the underbody must be cleaned periodically. For additional protection against rust and corro- sion, which may be required in some areas, con- sult a NISSAN dealer.

MAINTENANCE REQUIREMENTS


GENERAL MAINTENANCE


Your new NISSAN has been designed to have minimum maintenance requirements with long service intervals to save you both time and money. However, some day-to-day and regular maintenance is essential to maintain your NIS- SAN(cid:146)s good mechanical condition, as well as its emission and engine performance.


It is the owner(cid:146)s responsibility to make sure that the scheduled maintenance, as well as general maintenance, is performed.


As the vehicle owner, you are the only one who can ensure that your vehicle receives proper maintenance. You are a vital link in the mainte- nance chain. Scheduled maintenance


For your convenience, both required and optional scheduled maintenance items are described and listed in your (cid:147)NISSAN Service and Maintenance Guide.(cid:148) You must refer to that guide to ensure that necessary maintenance is performed on your NISSAN at regular intervals. General maintenance


General maintenance includes those items which should be checked during normal day-to-day op- eration. They are essential for proper vehicle op- eration. It is your responsibility to perform these maintenance procedures regularly as prescribed. 8-2 Maintenance and do-it-yourself


Performing general maintenance checks requires minimal mechanical skill and only a few general automotive tools. These checks or inspections can be done by you, a qualified technician, or, if you prefer, a NISSAN dealer. Where to go for service If maintenance service is required or your vehicle appears to malfunction, have the systems checked and corrected by a NISSAN dealer. NISSAN technicians are well-trained specialists who are kept up-to-date with the latest service information through technical bulletins, service tips, and in-dealership training programs. They are completely qualified to work on NISSAN ve- hicles before they work on your vehicle, rather than after they have worked on it. You can be confident that a NISSAN dealer(cid:146)s service department performs the best job to meet the maintenance requirements on your vehicle (cid:151) in a reliable and economical way.


During the normal day-to-day operation of the vehicle, general maintenance should be per- formed regularly as prescribed in this section. If you detect any unusual sounds, vibrations or smells, be sure to check for the cause or have a NISSAN dealer do it promptly. In addition, you should notify a NISSAN dealer if you think that repairs are required.


When performing any checks or maintenance work, closely observe the (cid:147)Maintenance precau- tions(cid:148) later in this section. EXPLANATION OF GENERAL MAINTENANCE ITEMS information on the following Additional items with (cid:147)*(cid:148) is found later in this section. Outside the vehicle The maintenance items listed here should be performed from time to time, unless otherwise specified. Doors and engine hood Check that the doors and engine hood operate properly. Also ensure that all latches lock securely. Lubricate hinges, latches, latch pins, rollers and links as necessary. Make sure that the secondary latch keeps the hood from opening when the primary latch is released.


Z REVIEW COPY—2008 Altima (alt) Owners Manual—USA_English (nna) 10/03/07—debbie X


When driving in areas using road salt or other corrosive materials, check lubrication frequently. Lights* Clean the headlights on a regular basis. Make sure that the headlights, stop lights, tail lights, turn signal lights, and other lights are all operating properly and installed securely. Also check headlight aim. Road wheel nuts (lug nuts)* When checking the tires, make sure no wheel nuts are missing, and check for any loose wheel nuts. Tighten if necessary. Tire rotation* Tires should be rotated every 7,500 miles (12,000 km). Tires* Check the pressure with a gauge often and always prior to long distance trips. If neces- sary, adjust the pressure in all tires, including the spare, to the pressure specified. Check carefully for damage, cuts or excessive wear. Tire Pressure Monitoring System (TPMS) transmitter components Replace the TPMS transmitter grommet seal, valve core and cap when the tires are replaced due to wear or age. Wheel alignment and balance If the vehicle should pull to either side while driving on a straight and level road, or if you detect uneven or abnormal tire wear, there may be a need for wheel


alignment. If the steering wheel or seat vibrates at normal highway speeds, wheel balancing may be needed. c For additional


information regarding tires, refer to (cid:147)Important Tire Safety Information(cid:148) (US) or (cid:147)Tire Safety Information(cid:148) (Canada) in the Warranty Information Booklet .


Windshield Clean the windshield on a regular basis. Check the windshield at least every six months for cracks or other damage. Have a dam- aged windshield repaired by a qualified repair facility. Windshield wiper blades* Check for cracks or wear if they do not wipe properly. Inside the vehicle The maintenance items listed here should be checked on a regular basis, such as when per- forming periodic maintenance, cleaning the ve- hicle, etc. Additional information on the following items with an (cid:147)*(cid:148) is found later in this sec- tion.


Accelerator pedal Check the pedal for smooth operation and make sure the pedal does not bind or require uneven effort. Keep the floor mat away from the pedal.


Brake pedal Check the pedal for smooth opera- tion. If the brake pedal suddenly goes down fur- ther than normal, the pedal feels spongy or the vehicle seems to take longer to stop, see a NISSAN dealer immediately. Keep the floor mat away from the pedal. Brakes Check that the brakes do not pull the vehicle to one side when applied. Continuously Variable Transmission (CVT) P (Park) position mechanism On a fairly steep hill check that the vehicle is held securely with the selector lever in the P (Park) position without applying any brakes. Parking brake Check the parking brake opera- tion regularly. The vehicle should be securely held on a fairly steep hill with only the parking brake applied. If the parking brake needs adjustment, see a NISSAN dealer. Seats Check seat position controls such as seat adjusters, seatback recliner, etc. to ensure they operate smoothly and all latches lock securely in every position. Check that the head restraints move up and down smoothly and the locks (if so equipped) hold securely in all latched positions. Seat belts Check that all parts of the seat belt system (for example, buckles, anchors, adjusters and retractors) operate properly and smoothly,

Radiator and hoses Check the front of the radiator and clean off any dirt, insects, leaves, etc., that may have accumulated. Make sure the hoses have no cracks, deformation, rot or loose connections. Underbody The underbody is frequently ex- posed to corrosive substances such as those used on icy roads or to control dust. It is very important to remove these substances from the underbody, otherwise rust may form on the floor pan, frame, fuel lines and exhaust system. At the end of winter, the underbody should be thor- oughly flushed with plain water, in those areas where mud and dirt may have accumulated. See the (cid:147)Appearance and care(cid:148) section of this manual. Windshield washer fluid* Check that there is adequate fluid in the reservoir.


and are installed securely. Check the belt web- bing for cuts, fraying, wear or damage. Steering wheel Check for changes in the steer- ing system, such as excessive freeplay, hard steering or strange noises. Warning lights and chimes Make sure all warning lights and chimes are operating properly. Windshield wiper and washer* Check that the wipers and washer operate properly and that the wipers do not streak. Windshield defroster Check that the air comes out of the defroster outlets properly and in sufficient quantity when operating the heater or air conditioner. Under the hood and vehicle The maintenance items listed here should be checked periodically (for example, each time you check the engine oil or refuel). Battery* Check the fluid level It should be between the MAX and MIN lines. Ve- hicles operated in high temperatures or under severe conditions require frequent checks of the battery fluid level. Brake and clutch fluid levels* Make sure that the brake and clutch fluid level is between the MIN and MAX lines on the reservoir. 8-4 Maintenance and do-it-yourself


in each cell.


Engine coolant level* Check the coolant level when the engine is cold. Engine drive belts* Make sure the drive belts are not frayed, worn, cracked or oily. Engine oil level* Check the level after parking the vehicle on a level surface with the engine off. Wait more than 10 minutes for the oil to drain back into the oil pan. Exhaust system Make sure there are no loose supports, cracks or holes. If the sound of the exhaust seems unusual or there is a smell of exhaust fumes, immediately have the exhaust system inspected by a NISSAN dealer. See the carbon monoxide warning in the (cid:147)Starting and driving(cid:148) section of this manual. Fluid leaks Check under the vehicle for fuel, oil, water or other fluid leaks after the vehicle has been parked for a while. Water dripping from the air conditioner after use is normal. If you should notice any leaks or if gasoline fumes are evident, check for the cause and have it corrected imme- diately. Power steering fluid level* and lines Check the level when the fluid is cold, with the engine off. Check the lines for proper attachment, leaks, cracks, etc.

MAINTENANCE PRECAUTIONS


When performing any inspection or maintenance work on your vehicle, always take care to prevent serious accidental injury to yourself or damage to the vehicle. The following are general precau- tions which should be closely observed.


WARNING


c Park the vehicle on a level surface, ap- ply the parking brake securely and block the wheels to prevent the vehicle from moving. For manual transmission models, move the shift lever to N (Neu- tral). For CVT models, move the selector lever to P (Park).


c Be sure the ignition key is in the OFF or LOCK position when performing any parts replacement or repairs.


c If you must work with the engine run- ning, keep your hands, clothing, hair and tools away from moving fans, belts and any other moving parts.


c It is advisable to secure or remove any loose clothing and remove any jewelry, such as rings, watches, etc. before working on your vehicle.


c Always wear eye protection whenever


you work on your vehicle.


c Your vehicle is equipped with an auto- matic engine cooling fan. It may come on at any time without warning, even if the ignition key is in the OFF position and the engine is not running. To avoid injury, always disconnect the negative battery cable before working near the fan.


c If you must run the engine in an en- closed space such as a garage, be sure there is proper ventilation for exhaust gases to escape.


c Never get under the vehicle while it is supported only by a jack. If it is neces- sary to work under the vehicle, support it with safety stands.


c Keep smoking materials,


flame and sparks away from the fuel tank and battery.


c On gasoline engine models, the fuel filter or fuel lines should be serviced by a NISSAN dealer because the fuel lines are under high pressure even when the engine is off.


CAUTION


c Do not work under the hood while the engine is hot. Turn the engine off and wait until it cools down.


c Avoid contact with used engine oil and coolant. Improperly disposed engine oil, engine coolant and/or other vehicle fluids can damage the environment. Al- ways conform to local regulations for disposal of vehicle fluid.


c Never leave the engine or the CVT re- lated component harness connector disconnected while the ignition switch is in the ON position.


c Never connect or disconnect the battery or any transistorized component while the ignition switch is in the ON position.


This (cid:147)Maintenance and do-it-yourself(cid:148) section gives instructions regarding only those items which are relatively easy for an owner to perform. A genuine NISSAN service manual is also avail- able. See (cid:147)Owner(cid:146)s Manual/Service Manual or- der information(cid:148) in the (cid:147)Technical and consumer information(cid:148) section of this manual. You should be aware that incomplete or improper servicing may result in operating difficulties or excessive emissions, and could affect warranty coverage. If in doubt about any servicing, have it done by a NISSAN dealer.

CHECKING ENGINE COOLANT LEVEL Check the coolant level in the reservoir when the engine is cold. If the coolant level is below the MIN level sB , add coolant to the MAX level sA . If the reservoir is empty, check the coolant level in the radiator when the engine is cold. If there is insufficient coolant in the radiator, fill the radiator with coolant up to the filler opening and also add it to the reservoir up to the MAX level sA . If the cooling system frequently requires coolant, have it checked by a NISSAN dealer.


Z REVIEW COPY—2008 Altima (alt) Owners Manual—USA_English (nna) 10/03/07—debbie X


CHANGING ENGINE COOLANT A NISSAN dealer can change the engine coolant. The service procedure can be found in the NISSAN Service Manual. Improper servicing can result in reduced heater performance and engine overheat- ing.


WARNING


c To avoid the danger of being scalded, never change the coolant when the en- gine is hot.


c Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pressure fluid escaping from the radiator.


c Avoid direct skin contact with used coolant. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.


c Keep coolant out of the reach of chil-


dren and pets.


Engine coolant must be disposed of properly. Check your local regulations.

CHECKING ENGINE OIL LEVEL 1. Park the vehicle on a level surface and apply


the parking brake.


2. Start the engine and let it idle until it reaches


operating temperature.


3. Turn off the engine. Wait more than 10
minutes for the oil to drain back into the oil pan.


4. Remove the dipstick and wipe it clean. Re-


insert it all the way.


5. Remove the dipstick again and check the oil level. It should be between the H (High) and L (Low) marks sB . This is the normal oper- ating oil level range. If the oil level is below the L (Low) mark sA , remove the oil filler cap and pour through the recommended oil opening. Do not overfill sC .

WINDOW WASHER FLUID RESERVOIR Fill the window washer fluid reservoir periodically. Add window washer fluid when the low window washer fluid warning light comes on (if so equipped).


To fill the window washer fluid reservoir, lift the cap off the reservoir tank and pour the window washer fluid into the tank opening.


Add a washer solvent to the washer for better cleaning. In the winter season, add a windshield washer antifreeze. Follow the manufacturer(cid:146)s in- structions for the mixture ratio.


Refill the reservoir more frequently when driving conditions require an increased amount of win- dow washer fluid. Recommended fluid is Genuine NISSAN Wind- shield Washer Concentrate Cleaner & Anti- freeze or equivalent.


CAUTION


c Do not substitute engine anti-freeze coolant for window washer solution. This may result in damage to the paint. c Do not fill the window washer reservoir tank with washer fluid concentrates at full strength. Some methyl alcohol based washer fluid concentrates may permanently stain the grille if spilled while filling the window washer reser- voir tank.


c Pre-mix washer fluid concentrates with water to the manufacturer(cid:146)s recom- mended levels before pouring the fluid into the window washer reservoir tank. Do not use the window washer reservoir tank to mix the washer fluid concen- trate and water.

BATTERY


c Keep the battery surface clean and dry. Clean the battery with a solution of baking soda and water.


c Make certain the terminal connections are


clean and securely tightened.


c If the vehicle is not to be used for 30 days or longer, disconnect the negative (-) battery terminal cable to prevent discharge.


WARNING


c Do not expose the battery to flames or electrical sparks. Hydrogen gas gener- ated by the battery is explosive. Do not allow battery fluid to contact your skin, eyes, fabrics or painted surfaces. After touching a battery or battery cap, do not touch or rub your eyes. Thoroughly wash your hands. If the acid contacts your eyes, skin or clothing, immediately flush with water for at least 15 minutes and seek medical attention.


c Do not operate the vehicle if the fluid in the battery is low. Low battery fluid can cause a higher load on the battery which can generate heat, reduce bat- tery life, and in some cases lead to an explosion.


c When working on or near a battery, al- ways wear suitable eye protection and remove all jewelry.


c Battery posts, terminals and related ac- cessories contain lead and lead com- pounds. Wash hands after handling.

BRAKES


FUSES


If the brakes do not operate properly, have the brakes checked by a NISSAN dealer. SELF-ADJUSTING BRAKES Your vehicle is equipped with self-adjusting brakes.


The front and rear disc-type brakes self-adjust every time the brake pedal is applied.


WARNING


See a NISSAN dealer for a brake system check if the brake pedal height does not return to normal.


BRAKE PAD WEAR INDICATORS The disc brake pads on your vehicle have audible wear indicators. When a brake pad requires re- placement, a high pitched scraping or screech- ing sound will be heard when the vehicle is in motion. The noise will be heard whether or not the brake pedal is depressed. Have the brakes checked as soon as possible if the wear indicator sound is heard.


Under some driving or climate conditions, occa- sional brake squeak, squeal or other noise may be heard. Occasional brake noise during light to moderate stops is normal and does not affect the function or performance of the brake system.


Proper brake inspection intervals should be followed. For more information regarding brake inspections, see the appropriate mainte- nance schedule information in the (cid:147)NISSAN Ser- vice and Maintenance Guide(cid:148).

WHEELS AND TIRES


If you have a flat tire, see the (cid:147)In case of emergency(cid:148) section of this manual. TIRE PRESSURE Tire Pressure Monitoring System (TPMS) This vehicle is equipped with the Tire Pressure Monitoring System (TPMS). It monitors tire pressure of all tires except the spare. When the low tire pressure warning light is lit, one or more of your tires is significantly under-inflated. The TPMS will activate only when the vehicle is driven at speeds above 16 MPH (25 km/h). Also, this system may not de- tect a sudden drop in tire pressure (for example a flat tire while driving). For more details, refer to (cid:147)Low tire pres- sure warning light(cid:148) in the (cid:147)Instruments and controls(cid:148) section, (cid:147)Tire Pressure Monitor- ing System (TPMS)(cid:148) in the (cid:147)Starting and driving(cid:148) section, and (cid:147)Flat tire(cid:148) in the (cid:147)In case of emergency(cid:148) section.


Tire inflation pressure Check the tire pressures (including the spare) often and always prior to long dis- tance trips. The recommended tire pres- sure specifications are shown on the F.M.V.S.S./C.M.V.S.S. certification label or the Tire and Loading Information label under the (cid:147)Cold Tire Pressure(cid:148) heading. The Tire and Loading Information label is affixed to the driver side center pillar. Tire pressures should be checked regularly because: c Most tires naturally lose air over time. c Tires can lose air suddenly when driven over potholes or other objects or if the vehicle strikes a curb while parking.


The tire pressures should be checked when the tires are cold. The tires are considered COLD after the vehicle has been parked for 3 or more hours, or driven less than 1 mile (1.6 km) at moderate speeds.

Over- loading your vehicle may result in reduced tire life, unsafe operat- ing conditions due to premature tire failure, or unfavorable han- dling characteristics and could also lead to a serious accident. Loading beyond the specified ca- pacity may also result in failure of other vehicle components.


c Before taking a long trip, or whenever you heavily load your vehicle, use a tire pressure gauge to ensure that the tire pressures are at the specified level.


c Do not drive your vehicle over 85
MPH (137 km/h) unless it is equipped with high speed rated tires. Driving faster than 85 MPH (137 km/h) may result in tire fail- ure, loss of control and possible injury.

s4 Cold tire pressure: Inflate the tires to this pressure when the tires are cold. Tires are considered COLD after the vehicle has been parked for 3 or more hours, or driven less than 1 mile (1.6
km) at moderate speeds. The recom- mended cold tire inflation is set by the manufacturer to provide the best bal- ance of tire wear, vehicle handling, driveability, tire noise, etc., up to the vehicle(cid:146)s GVWR.

4. Read the tire pressure on the gauge stem and compare to the specifica- tion shown on the Tire and Loading Information label.


5. Add air to the tire as needed. If too much air is added, press the core of the valve stem briefly with the tip of the gauge stem to release pressure. Recheck the pressure and add or release air as needed. Install the valve stem cap.


6. 7. Check the pressure of all other tires,


including the spare.


LDI0393


Checking tire pressure 1. Remove the valve stem cap from the


tire.


2. Press the pressure gauge squarely onto the valve stem. Do not press too hard or force the valve stem side- ways, or air will escape. If the hissing sound of air escaping from the tire is heard while checking the pressure, reposition the gauge to eliminate this leakage.


3. Remove the gauge. 8-36 Maintenance and do-it-yourself

TIRE LABELING Federal law requires tire manufacturers to place standardized information on the sidewall of all tires. This information iden- tifies and describes the fundamental characteristics of the tire and also pro- vides the tire identification number (TIN) for safety standard certification. The TIN can be used to identify the tire in case of a recall.

2. Three-digit number (215): This num- ber gives the width in millimeters of the tire from sidewall edge to side- wall edge.


3. Two-digit number (65): This number, known as the aspect ratio, gives the tire(cid:146)s ratio of height to width.

4. R: The 9R9 stands for radial. 5. Two-digit number (15): This number is the wheel or rim diameter in inches. 6. Two- or three-digit number (95): This number is the tire(cid:146)s load index. It is a measurement of how much weight each tire can support. You may not find this information on all tires be-
