WINDSHIELD WIPER BLADES

CLEANING If your windshield is not clear after using the windshield washer or if a wiper blade chatters when running, wax or other material may be on the blade or windshield. Clean the outside of the windshield with a washer solution or a mild detergent. Your windshield is clean if beads do not form when rinsing with clear water. Clean each blade by wiping it with a cloth soaked in a washer solution or a mild detergent. Then rinse the blades with clear water. If your wind- shield is still not clear after cleaning the blades and using the wiper, replace the blades.

CAUTION

Worn windshield wiper blades can dam- age the windshield and impair driver vision.

REPLACING Replace the wiper blades if they are worn. s1
Lift the wiper arm away from the windshield. s2 Push the release tab, then move the wiper

blade down the wiper arm to remove.

s3 Remove the wiper blade.

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). BRAKE BOOSTER Check the brake booster function as follows: 1. With the engine off, press and release the brake pedal several times. When brake pedal movement (distance of travel) remains the same from one pedal application to the next, continue on to the next step.

2. While depressing the brake pedal, start the engine. The pedal height should drop a little. 3. With the brake pedal depressed, stop the engine. Keep the pedal depressed for about 30 seconds. The pedal height should not change.

4. Run the engine for one minute without de- pressing the brake pedal, then turn it off. Depress the brake pedal several times. The pedal travel distance will decrease gradually with each depression as the vacuum is re- leased from the booster.

If the brakes do not operate properly, have the brakes checked by a NISSAN dealer.

COLD. Tires are considered COLD after the vehicle has been parked for three or more hours, or driven less than 1 mile (1.6 km) at moderate speeds. COLD tire pressures are shown on the tire placard affixed to the center console lid.

WARNING

c Improperly inflated tires can fail sud-

denly and cause an accident.

c The vehicle weight capacity is indicated on the F.M.V.S.S. certification label. Do not load your vehicle beyond this ca- pacity. Overloading your vehicle may result in reduced tire life, unsafe oper- ating conditions due to premature tire failure, or unfavorable handling charac- teristics and could also lead to a seri- ous accident. Loading beyond the specified capacity 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 failure, loss of control and possible injury.

c For additional

information regarding tires, refer to Important Tire Safety In- formation (US) or Tire Safety Informa- tion (Canada) in the Warranty Informa- tion Booklet.

TYPES OF TIRES

WARNING

c When changing or replacing tires, be sure all four tires are of the same type (i.e., Summer, All Season or Snow) and construction. A NISSAN dealer may be able to help you with information about tire type, size, speed rating and avail- ability. Replacement tires may have a lower speed rating than the factory equipped tires, and may not match the potential maximum vehicle speed. Never exceed the maximum speed rat- ing of the tire.

c For additional

information regarding tires, refer to Important Tire Safety In- formation (US) or Tire Safety Informa- tion (Canada) in the Warranty Informa- tion Booklet.

All season tires NISSAN specifies All Season tires on some mod- els to provide good performance all year, includ- ing snowy and icy road conditions. All Season tires are identified by ALL SEASON and/or M&S on the tire sidewall. Snow tires have better snow traction than All Season tires and may be more appropriate in some areas. Summer tires NISSAN specifies summer tires on some models to provide superior performance on dry roads. Summer tire performance is substantially re- duced in snow and ice. Summer tires do not have the tire traction rating (cid:147)M&S(cid:148) on the tire sidewall. If you plan to operate your vehicle in snowy or icy conditions, NISSAN recommends the use of SNOW tires or ALL SEASON tires on all four wheels. Snow tires If snow tires are needed, it is necessary to select tires equivalent in size and load rating to the Maintenance and do-it-yourself 8-41

the tire and the closest vehicle suspension or body component required to accommodate the use of a winter traction device (tire chains or cables). The minimum clearances are determined using the factory equipped tires. Other types may damage your vehicle. Use chain tensioners when recommended by the tire chain manufacturer to ensure a tight fit. Loose end links of the tire chain must be secured or removed to prevent the pos- sibility of whipping action damage to the fenders or underbody. If possible, avoid fully loading your vehicle when using tire chains. In addition, drive at a reduced speed. Otherwise, your vehicle may be damaged and/or vehicle handling and perfor- mance may be adversely affected. Tire chains must be installed only on the front wheels and not on the rear wheels. Never install tire chains on a TEMPORARY USE ONLY spare tire. Do not use tire chains on dry roads. Driving with chains in such conditions can cause damage to the various mechanisms of the vehicle due to some overstress.

If you do not,

Generally, snow tires have lower speed ratings than factory equipped tires and may not match the potential maximum vehicle speed. Never ex- ceed the maximum speed rating of the tire.

If you install snow tires, they must be the same size, brand, construction and tread pattern on all four wheels.

For additional traction on icy roads, studded tires may be used. However, some U.S. states and Canadian provinces prohibit their use. Check local, state and provincial laws before installing studded tires. Skid and traction capabilities of studded snow tires on wet or dry surfaces may be poorer than that of non-studded snow tires. TIRE CHAINS Use of tire chains may be prohibited according to location. Check the local laws before installing tire chains. When installing tire chains, make sure they are the proper size for the tires on your vehicle and are installed according to the chain manufacturer(cid:146)s suggestions. Use only SAE class (cid:147)S(cid:148) chains. Class (cid:147)S(cid:148) chains are used on vehicles with restricted tire to vehicle clearance. Vehicles that can use Class (cid:147)S(cid:148) chains are de- signed to meet the minimum clearances between 8-42 Maintenance and do-it-yourself

CHANGING WHEELS AND TIRES Tire rotation NISSAN recommends rotating the tires every 7,500 miles (12,000 km).

See (cid:147)Flat tire(cid:148) in the (cid:147)In case of emergency(cid:148) section of this manual for tire replacing proce- dures. As soon as possible, tighten the wheel nuts to the specified torque with a torque wrench.

Wheel nut tightening torque:

80 ft-lb (108 N•m)

Z REVIEW COPY:—2003 Altima (l30) Owners Manual (owners)—USA English (nna) 04/21/03—debbie X

The wheel nuts must be kept tightened to specifications at all times. It is recom- mended that wheel nuts be tightened to specification at each tire rotation interval.

WARNING

c After rotating the tires, check and ad-

just the tire pressure.

c Retighten the wheel nuts when the ve- hicle has been driven for 600 miles (1,000 km) (also in cases of a flat tire, etc.).

c Do not include the spare tire in the tire

rotation.

WARNING

c The use of tires other than those recom- mended or the mixed use of tires of different brands, construction (bias, bias-belted or radial), or tread patterns can adversely affect the ride, braking, handling, ground clearance, body-to- tire clearance, tire chain clearance, speedometer calibration, headlight aim and bumper height. Some of these ef- fects may lead to accidents and could result in serious personal injury.

c If the wheels are changed for any rea- son, always replace with wheels which have the same off-set dimension. Wheels of a different off-set could cause premature tire wear, degrade ve- hicle handling characteristics and/or interference brake discs/drums. Such interference can lead to decreased braking efficiency and/or early brake pad/shoe wear.

Wheel balance Unbalanced wheels may affect vehicle handling and tire life. Even with regular use, wheels can get out of balance. Therefore, they should be bal- anced as required. Wheel balance service should be per- formed with the wheels off the vehicle. Spin balancing the wheels on the vehicle could lead to mechanical damage. c For additional information regarding tires, refer to (cid:147)Important Tire Safety Information(cid:148) (US) or (cid:147)Tire Safety Infor- mation(cid:148) (Canada) in the Warranty In- formation Booklet .

Care of wheels c Wash the wheels when washing the vehicle

to maintain their appearance.

c Clean the inner side of the wheels when the is changed or the underside of the

wheel vehicle is washed.

c Do not use abrasive cleaners when washing

the wheels.

c Inspect wheel rims regularly for dents or corrosion. Such damage may cause loss of pressure or poor seal at the tire bead.

c NISSAN recommends waxing the road wheels to protect against road salt in areas where it is used during winter.

WARNING

c The spare tire should be used for emer- gency use only. It should be replaced with the standard tire at the first oppor- tunity to avoid possible tire or differen- tial damage.

c Drive carefully while the TEMPORARY USE ONLY spare tire is installed. Avoid sharp turns and abrupt braking while driving.

c Periodically check spare tire inflation pressure. Always keep the pressure of the TEMPORARY USE ONLY spare tire at 60 psi (420 kPa, 4.2 bar).

c With the TEMPORARY USE ONLY spare tire installed do not drive the vehicle at speeds faster than 50 MPH (80 km/h). c When driving on roads covered with snow or ice, the TEMPORARY USE ONLY spare tire should be used on the rear wheels and the original tire used on the front wheels (drive wheels). Use tire chains only on the front (original) tires.

c Tire tread of the TEMPORARY USE ONLY spare tire will wear at a faster rate than the standard tire. Replace the spare tire as soon as the tread wear indicators appear.

c Do not use the spare tire on other

vehicles.

c Do not use more than one spare tire at

the same time.

c Do not tow a trailer when the TEMPO- RARY USE ONLY spare tire is installed.

CAUTION

c Do not use tire chains on a TEMPO- RARY USE ONLY spare tire. Tire chains will not fit properly and may cause dam- age to the vehicle.

c Because the TEMPORARY USE ONLY spare tire is smaller than the original tire, ground clearance is reduced. To avoid damage to the vehicle, do not drive over obstacles. Also, do not drive the vehicle through an automatic car wash since it may get caught.

FUEL RECOMMENDATION For 2.5L engine

Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) num- ber (Research octane number 91). For 3.5L Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) num- ber (Research octane number 91). For improved vehicle performance, NISSAN rec- ommends the use of unleaded premium gasoline with an octane rating of at least 91 AKI number (Research octane number 96).

CAUTION

c Using a fuel other than that specified could adversely affect the emission control system, and may also affect the warranty coverage.

c Under no circumstances should a leaded gasoline be used, because this will damage the three-way catalyst.

Reformulated gasoline Some fuel suppliers are now producing reformu- lated gasolines. These gasolines are specially designed to reduce vehicle emissions. NISSAN

supports efforts towards cleaner air and sug- gests that you use reformulated gasoline when available. Gasoline containing oxygenates Some fuel suppliers sell gasoline containing oxy- genates such as ethanol, MTBE and methanol with or without advertising their presence. NISSAN does not recommend the use of fuels of which the oxygenate content and the fuel com- patibility for your NISSAN cannot be readily de- termined. If in doubt, ask your service station manager. If you use oxygenate-blend gasoline, please take the following precautions as the usage of such fuels may cause vehicle performance problems and/or fuel system damage. c The fuel should be unleaded and have an octane rating no lower than that recommended for unleaded gasoline. than methanol blend is used, it should con- tain no more than 10% oxygenate. (MTBE may, however, be added up to 15%.)

c If an oxygenate-blend other

c If a methanol blend is used, it should contain no more than 5% methanol (methyl alcohol, wood alcohol). It should also contain a suitable amount

of appropriate cosolvents and corro- sion inhibitors. If not properly formu- lated with appropriate cosolvents and corrosion inhibitors, such methanol blends may cause fuel system damage and/or vehicle performance problems. At this time, sufficient data is not avail- able to ensure that all methanol blends are suitable for use in NISSAN ve- hicles.

fuels,

oxygenate-blend

If any driveability problems such as engine stall- ing and difficult hot-starting are experienced after using immediately change to a non-oxygenate fuel or a fuel with a low blend of MTBE. Take care not to spill gasoline during refu- eling. Gasoline containing oxygenates can cause paint damage. Aftermarket fuel additives NISSAN does not recommend the use of any fuel additives (for example, fuel injector cleaner, oc- tane booster, intake valve deposit removers, etc.) which are sold commercially. Many of these ad- ditives intended for gum, varnish or deposit re- moval may contain active solvents or similar in- gredients that can be harmful to the fuel system and engine.

damage. If any of the above symptoms are en- countered, have your vehicle checked at a NISSAN dealer. However, now and then you may notice light spark knock for a short time while accelerating or driving up hills. This is not a cause for concern, because you get the greatest fuel benefit when there is light spark knock for a short time under heavy engine load.

Octane rating tips In most parts of North America, you should use unleaded gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number. How- ever, you may use unleaded gasoline with an octane rating as low as 85 AKI (Anti-Knock Index) number in high altitude areas [over 4,000 ft (1,219 m)] such as: Colorado, Montana, New Mexico, Utah, Wyoming, northeastern Nevada, southern Idaho, western South Dakota, western Nebraska, and the part of Texas which is directly south of New Mexico. Using unleaded gasoline with an octane rating lower than stated above can cause persistent, heavy (cid:147)spark knock.(cid:148) ((cid:147)Spark knock(cid:148) is a metallic rapping noise.) If se- vere, this can lead to engine damage. If you detect a persistent heavy spark knock even when using gasoline of the stated octane rating, or if you hear steady spark knock while holding a steady speed on level roads, have a NISSAN dealer correct the condition. Failure to correct the condition is misuse of the vehicle, for which NISSAN is not responsible.

ignition timing may result

Incorrect in spark knock, after-run and/or overheating, which may cause excessive fuel consumption or engine 9-4 Technical and consumer information

ENGINE OIL AND OIL FILTER RECOMMENDATION Selecting the correct oil It is essential to choose engine oil with the cor- rect quality and viscosity to ensure satisfactory engine life and performance. NISSAN recom- mends the use of a low friction oil (energy con- serving oil) in order to improve fuel economy and conserve energy. Oils which do not have the specified quality label should not be used as they could cause engine damage.

Only those engine oils with the American Petro- leum Institute (API) CERTIFICATION MARK on

WTI0082

the front of the container should be used. This type of oil supersedes the existing API SG, SH, or SJ and Energy Conserving II categories.

If you cannot find engine oil with the API CERTI- FICATION MARK, use API grade SL Energy Conserving oil. An oil with a single designation SL, or in combination with other categories (for example, SL/CF) may also be used if one with the API CERTIFICATION MARK cannot be found. An ILSAC grade GF-III oil can also be used.

NISSAN recommends mineral based oils. These oils must, however, meet the API quality and SAE viscosity ratings specified for your vehicle.

Oil additives NISSAN does not recommend the use of oil additives. The use of an oil additive is not neces- sary when the proper oil type is used and main- tenance intervals are followed.

Oil which may contain foreign matter or has been previously used should not be used. Oil viscosity The engine oil viscosity or thickness changes with temperature. Because of this, it is important to select the engine oil viscosity based on the temperatures at which the vehicle will be oper- ated before the next oil change. The chart (cid:147)Rec- ommended SAE viscosity number(cid:148) shows the recommended oil viscosities for the expected ambient temperatures. Choosing an oil viscosity other than that recommended could cause seri- ous engine damage. Selecting the correct oil filter Your new NISSAN vehicle is equipped with a high-quality genuine NISSAN oil filter. When re- placing, use a genuine NISSAN oil filter or its equivalent for the reason described in (cid:147)Change intervals(cid:148).

Technical and consumer information 9-5

Z REVIEW COPY:—2003 Altima (l30) Owners Manual (owners)—USA English (nna) 04/21/03—debbie X

Change intervals The oil and oil filter change intervals for your engine are based on the use of the specified quality oils and filters. Using engine oil and filters that are not of the specified quality, or exceeding recommended oil and filter change intervals could reduce engine life. Damage to the engine caused by improper maintenance or use of incor- rect oil and filter quality and/or viscosity is not covered by the NISSAN new vehicle warranty. Your engine was filled with a high-quality engine oil when it was built. You do not have to change the oil before the first recommended change interval. Oil and filter change intervals depend upon how you use your vehicle. Operation under the following conditions may require more frequent oil and filter changes: c repeated short distance driving at cold out-

side temperatures

c driving in dusty conditions c extensive idling c towing a trailer

AIR CONDITIONER SYSTEM REFRIGERANT AND LUBRICANT RECOMMENDATIONS The air conditioner system in your NISSAN vehicle must be charged with the refriger- ant HFC-134a (R-134a) and the lubricant, NISSAN A/C system oil DH-PS or the exact equivalents.

CAUTION

The use of any other refrigerant or lubri- cant will cause severe damage to the air conditioning system and will require the replacement of all air conditioner system components.

The refrigerant HFC-134a (R-134a) in your NISSAN vehicle does not harm the earth(cid:146)s ozone layer. Although this refrigerant does not affect the earth(cid:146)s atmosphere, certain government regula- tions require the recovery and recycling of any refrigerant during automotive air conditioner sys- tem service. A NISSAN dealer has the trained technicians and equipment needed to recover and recycle your air conditioner system refriger- ant. Contact a NISSAN dealer when servicing your air conditioner system.

ATI1028

RECOMMENDED SAE VISCOSITY NUMBER c SAE 5W-30 viscosity oil is preferred for all temperatures. SAE 10W-30 or SAE 10W-40 viscosity oils may be used if the ambient temperature is above 0(cid:176)F

VEHICLE LOADING INFORMATION

Use the following steps to mount the front license plate: s1 Make a shallow hole in each plastic finisher at the location mark (small dimple) using a 0.31 in (8 mm) drill. To avoid damaging the threads behind the finisher, apply only light pressure to the drill.

s2 Mount the license plate bracket using two of the four 8 mm slotted hex head screws. 3. Use the remaining two 8 mm slotted hex head screws to mount the license plate to the license plate bracket.

CAUTION

c It is extremely dangerous to ride in a cargo area inside a vehicle. In a colli- sion, people riding in these areas are more likely to be seriously injured or killed.

c Do not allow people to ride in any area of your vehicle that is not equipped with seats and seat belts.

c Be sure everyone in your vehicle is in a

seat and using a seat belt properly.

TERMS It is important to familiarize yourself with the fol- lowing terms before loading your vehicle: c Curb Weight (actual weight of your vehicle) - vehicle weight including: standard and op- tional equipment, fluids, emergency tools, and spare tire assembly. This weight does not include passengers and cargo.

c GVW (Gross Vehicle Weight) - curb weight plus the combined weight of passengers and cargo.

c GVWR (Gross Vehicle Weight Rating) - maximum total weight (load) limit specified for the vehicle.

c GAWR (Gross Axle Weight Rating) - maxi- mum weight (load) limit specified for the front or rear axle.

DETERMINING VEHICLE LOAD CAPACITY The load capacity of this vehicle is determined by weight, not by available cargo space. For ex- ample, a luggage rack, bike carrier, cartop carrier or similar equipment does not increase load car- rying capacity of your vehicle.

To determine vehicle load capacity:

Vehicle weight can be determined by using a commercial-grade scale, found at places such as a truck stop, gravel quarry, grain elevator, or a scrap metal recycling facility.

1. Determine the curb weight of your vehicle.

2. Compare the curb weight amount to the GVWR specified for your vehicle to deter- mine how much more weight your vehicle can carry.

3. After loading (cargo and passengers), re- weigh your vehicle to determine if either GVWR or GAWR for your vehicle is ex- ceeded. remove cargo as necessary. If either the front or rear GAWR is exceeded, shift the load or remove cargo as necessary.

If GVWR is exceeded,

LOADING TIPS c The GVW must not exceed GVWR or GAWR as specified on the F.M.V.S.S. certi- fication label.

c Do not load the front and rear axle to the

GAWR. Doing so will exceed the GVWR.

WARNING

c Properly secure all cargo with ropes or straps to help prevent it from sliding or shifting. Do not place cargo higher than the seatbacks. In a sudden stop or col- lision, unsecured cargo could cause personal injury.

c Do not load your vehicle any heavier than the GVWR or the maximum front and rear GAWRs. If you do, parts of your vehicle can break, tire damage could occur, or it can change the way your vehicle handles. This could result in loss of control and cause personal injury.

c Overloading can shorten the life of the vehicle. Failures caused by overloading are not covered by the vehicle(cid:146)s warranty.

CAUTION

Vehicle damage resulting from improper towing procedures are not covered by NISSAN warranties. A NISSAN Trailer Towing Guide (U.S. only) containing infor- mation on trailer towing ability and the special equipment required may be ob- tained from a NISSAN dealer.

TOWING A TRAILER

Your new vehicle was designed to be used pri- marily to carry passengers and cargo. Remember that towing a trailer places additional loads on your vehicle(cid:146)s engine, drive train, steering, brak- ing and other systems. A Nissan Trailer Towing Guide (U.S. only) is available from a NISSAN dealer. This guide in- cludes information on trailer towing ability and the special equipment required for proper towing. MAXIMUM LOAD LIMITS Maximum trailer loads Never allow the total trailer load to exceed the value specified in the Towing Load/Specification Chart found later in this section. The total trailer load equals trailer weight plus its cargo weight. Towing loads greater than specified or using improper towing equipment could adversely af- fect vehicle handling, braking and performance.

The ability of your vehicle to tow a trailer is not only related to the maximum trailer loads, but also the places you plan to tow. Tow weights appro- priate for level highway driving may have to be reduced on very steep grades or in low traction situations (for example, on slippery boat ramps).

c Do not modify the vehicle exhaust sys- tem, brake system, etc. to install a trailer hitch.

c To reduce the possibility of additional damage if your vehicle is struck from the rear, where practical, remove the hitch and/or receiver when not in use. c After the hitch is removed, seal the bolt holes to prevent exhaust fumes, water or dust from entering the passenger compartment.

c Regularly check that all trailer hitch mounting bolts are securely mounted.

Tire pressures c When towing a trailer, inflate the vehicle tires to the recommended cold tire pressure indi- cated on the tire placard.

c Trailer tire condition, size,

load rating and proper inflation pressure should be in accor- dance with the trailer and tire manufacturer(cid:146)s specifications.

Safety chains Always use suitable safety chains between your vehicle and the trailer. Safety chains should be crossed and should be attached to the hitch, not

to the vehicle bumper or axle. Be sure to leave enough slack in the chains to permit turning corners. Trailer lights Trailer lights should comply with federal and/or local regulations. When wiring the vehicle for towing, connect the stop and tail light pickup into the vehicle electrical circuit. Trailer brakes If your trailer is equipped with a braking system, make sure it conforms to federal and/or local regulations and that it is properly installed.

WARNING

Never connect a trailer brake system di- rectly to the vehicle brake system. Pre-towing tips c Be certain your vehicle maintains a level position when a loaded and/or unloaded trailer is hitched. Do not drive the vehicle if it has an abnormal nose-up or nose-down condition; check for improper tongue load, overload, worn suspension or other possible causes of either condition.

c Always secure items in the trailer to prevent

load shift while driving.

c Be certain your rear view mirrors conform to all federal, state or local regulations. If not, install any mirrors required for towing before driving the vehicle. Trailer towing tips In order to gain skill and an understanding of the vehicle(cid:146)s behavior, you should practice turning, stopping and backing up in an area which is free from traffic. Steering stability and braking perfor- mance will be somewhat different than under normal driving conditions. c Always secure items in the trailer to prevent

load shift while driving.

c Avoid abrupt starts, acceleration or stops. c Avoid sharp turns or lane changes. c Always drive your vehicle at a moderate speed. c Always block the wheels on both vehicle and trailer when parking. Parking on a slope is not recommended; however, if you must do so, and if your vehicle is equipped with an automatic transmission, first block the wheels and apply the parking brake, and then move the transmission shift selector lever into the P (Park) position. If you move the shift selector lever to the P (Park) posi- tion before blocking the wheels and applying the parking brake, transmission damage could occur.

9-16 Technical and consumer information

c When going down a hill, shift into a lower gear and use the engine braking effect. When going up a long grade, downshift the transmission to a lower gear and reduce speed to reduce chances of engine over- loading and/or overheating. However, for long steep grades, do not stay in 1st or 2nd gear when driving above 35 MPH (56 km/h). c If the engine coolant rises to an extremely high temperature when the air conditioner system is on, turn off the air conditioner. Coolant heat can be additionally vented by opening the windows, switching the fan control to high and setting the temperature control to the HOT position.

c Trailer towing requires more fuel than normal

circumstances.

c Avoid towing a trailer for your vehicle(cid:146)s first

500 miles (805 km).

c Have your vehicle serviced more often than at intervals specified in the recommended Maintenance Schedule in the (cid:147)NISSAN Ser- vice and Maintenance Guide(cid:148).

c When making a turn, your trailer wheels will be closer to the inside of the turn than your vehicle wheels. To compensate for this, make a larger than normal turning radius during the turn.

When being passed by larger vehicles, be prepared for possible changes in crosswinds that could affect ve- hicle handling. If swaying does occur, firmly grip the steering wheel, steer straight ahead, and immediately (but gradually) reduce ve- hicle speed. This combination will help sta- bilize the vehicle. Never increase speed.

c Be careful when passing other vehicles. Passing while towing a trailer requires con- siderably more distance than normal pass- ing. Remember, the length of the trailer must also pass the other vehicle before you can safely change lanes.

c To maintain engine braking efficiency and electrical charging performance, do not use 5th gear (manual transmission) or overdrive (automatic transmission).

c Avoid holding the brake pedal down too long or too frequently. This could cause the brakes to overheat, resulting in reduced braking efficiency.

transmission When towing a trailer, oil/fluid should be changed more fre- quently. For additional information, see the (cid:147)Maintenance and do-it-yourself(cid:148) section earlier in this manual.

UNIFORM TIRE QUALITY GRADING

DOT (Department of Transportation) Quality Grades: All passenger car tires must conform to federal safety requirements in addition to these grades.

Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A

Treadwear

Treadwear grade is a comparative rating based on tire wear rate when tested under controlled conditions on specified government test courses. For example, a tire graded 150 would wear one and a half (1-1/2) times as well on the govern- ment course as a tire graded 100. However, relative tire performance depends on actual driv- ing conditions, and may vary significantly due to variations in driving habits, service practices and differences in road characteristics and climate.

Traction AA, A, B and C

The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire(cid:146)s ability to stop on wet pavement as mea- sured under controlled conditions on specified government test surfaces of asphalt and con- crete. A tire marked C may have poor traction performance.

WARNING

The traction grade assigned to your ve- hicle tires is based on straight-ahead braking traction tests and does not in- clude acceleration, cornering, hydroplan- ing or peak traction characteristics.

Temperature A, B and C

Temperature grades are A (the highest), B, and C. They represent a tire(cid:146)s resistance to heat build-up, and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high tem- perature can cause tire material to degenerate, reducing tire life. Excessive temperatures can lead to sudden tire failure. Grade C corresponds to a performance level which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades A and B rep- resent higher levels of performance on laboratory test wheels than the minimum required by law.

WARNING

The temperature grade for this tire is es- tablished for a tire that is properly inflated and not overloaded. Excessive speed, under-inflation, or excessive loading, ei- ther separately or in combination, can cause heat build-up and possible tire failure.

READINESS FOR INSPECTION/ MAINTENANCE (I/M) TEST

Due to legal requirements in some states and Canadian Provinces, your vehicle may be re- quired to be in what is called the (cid:147)ready condi- tion(cid:148) for an Inspection/Maintenance (I/M) test of the emission control system.

The vehicle is set to the (cid:147)ready condition(cid:148) when it is driven through certain driving patterns. Usually, the ready condition can be obtained by ordinary usage of the vehicle.

If a powertrain system component is repaired or the battery is disconnected, the vehicle may be reset to a (cid:147)not ready(cid:148) condition. Before taking the I/M test, drive the vehicle through the following pattern to set the vehicle to the ready condition. If you cannot or do not want to perform the driving pattern, a NISSAN dealer can conduct it for you.

WARNING

Always drive the vehicle in a safe and prudent manner according to traffic con- ditions and obey all traffic laws.

1. Start the engine when the engine coolant temperature gauge needle points to C. Al- low the engine to idle until the gauge needle points between the C and H (normal oper- ating temperature).

2. Accelerate the vehicle to 55 MPH (88
km/h), then quickly release the accelerator pedal completely and keep it released for at least 6 seconds.

3. Quickly depress the accelerator pedal for a moment, then drive the vehicle at a speed of 53 - 60 MPH (86 - 96 km/h) for at least 5
minutes.

4. Stop the vehicle. 5. Accelerate the vehicle to 35 MPH (55 km/h)

and maintain the speed for 20 seconds.
