Any service items not detailed in this section should be performed by a Honda technician or other qualified mechanic. Some of the most important safety precautions are given here. However, we cannot warn you of every conceivable hazard that can arise in performing maintenance. Only you can decide whether or not you should perform a given task. Failure to properly follow maintenance instructions and precautions can cause you to be seriously hurt or killed. Always follow the procedures and precautions in this owner's manual. Maintenance Safety Regularly maintaining your vehicle is the best way to protect your investment. Proper maintenance is essential to your safety and the safety of your passengers. It will also reward you with more economical, trouble-free driving and help reduce air pollution. Improperly maintaining this vehicle or failing to correct a problem before driving can cause a crash in which you can be seriously hurt or killed. Always follow the inspection and maintenance recommendations and schedules in this owner's manual. Maintenance Main MenuTable of ContentsstImportant Safety Precautions Before you begin any maintenance, make sure your vehicle is parked on level ground and that the parking brake is set. Also, be sure the engine is off. This will help to eliminate several potential hazards: Carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation whenever you operate the engine. Burns from hot parts. Let the engine and exhaust system cool before touching any parts. Injury from moving parts. Do not run the engine unless in- structed to do so. Read the instructions before you begin, and make sure you have the tools and skills required. To reduce the possibility of fire or explosion, be careful when working around gasoline or batteries. Use a nonflammable solvent, not gasoline, to clean parts. Keep cigarettes, sparks, and flames away from the battery and all fuel-related parts. You should wear eye protection and protective clothing when working near the battery or when using compressed air. Maintenance Safety Maintenance Main MenuTable of ContentsstWhich Schedule to Follow: Service your vehicle according to the time and mileage periods on one of the Maintenance Schedules on the following pages. Select the schedule for "Severe Conditions" if most of your driving is done under one or more of the conditions listed on that page. Otherwise, follow the schedule for "Normal Conditions." Maintenance Schedule The Maintenance Schedule specifies how often you should have your vehicle serviced and what things need attention. It is essential that you have your vehicle serviced as scheduled to retain its high level of safety, dependability, and emissions control performance. The services and time or distance intervals shown in the maintenance schedule assume you will use your vehicle as normal transportation for passengers and their possessions. You should also follow these recommendations: Avoid exceeding your vehicle's load limit. This puts excess stress on the engine, brakes, and many other parts of your vehicle. The load limit is shown on the label on the driver's doorjamb. Operate your vehicle on reasonable roads within the legal speed limit. Drive your vehicle regularly over a distance of several miles (kilometers). Always use unleaded gasoline with the proper octane rating (see page 120). Maintenance Main MenuTable of ContentsstYour authorized Honda dealer knows your vehicle best and can provide competent, efficient service. However, service at a dealer is not mandatory to keep your warranties in effect. Maintenance may be done by any qualified service facility or person who is skilled in this type of automotive service. Keep all the receipts as proof of completion, and have the person who does the work fill out the Maintenance Record. Check your warranty booklet for more information. We recommend the use of Genuine Honda parts and fluids whenever you have maintenance done. These are manufactured to the same high- quality standards as the original components, so you can be confident of their performance and durability. U.S. Vehicles: Maintenance, replacement or repair of emission control devices and systems may be done by any automotive repair establishment or individual using parts that are "certified" to EPA standards. Maintenance Schedule According to state and federal regulations, failure to perform maintenance on the items marked with # will not void your emissions warranties. However, Honda recommends that all maintenance services be performed at the recommended time or mileage period to ensure long-term reliability. Maintenance Main MenuTable of ContentsstMaintenance Schedule (Normal Conditions) Follow the Normal Conditions Maintenance Schedule if the severe driving conditions specified in the Severe Conditions Maintenance Schedule do not apply.

Pour in the oil, and replace the engine oil fill cap. Tighten it securely. Wait a few minutes and recheck the oil level. Do not fill above the upper mark; you could damage the engine. Recommended Oil Oil is a major contributor to your engine's performance and longevity. Always use a premium-grade deter- gent oil. You can determine an oil's SAE viscosity and Service Classification from the API Service label on the oil container. A fuel-efficient oil is recommended for your Honda. This is shown on the API Service label by the words "Energy Conserving". This oil is formulated to help your engine use less fuel. Engine Oil The API Service label also tells you the service classification of the oil. Always use an oil that is labeled "API Service SJ". This service rating may include other classifications, such as CD. These additional classifications are not a problem, as long as the label also carries the SJ classification. API SERVICE LABEL CONTINUED Maintenance Main MenuTable of ContentsstEngine Oil The oil container may also display the API Certification seal. Make sure it says "For Gasoline Engines." The SAE numbers tell you the oil's viscosity or weight. Select the oil for your vehicle according to this chart. API CERTIFICATION SEAL Ambient Temperature An oil with a viscosity of 5W-30 is preferred for improved fuel economy and year-round protection in your Honda. You may use a 10W-30 oil if the temperature in your area never goes below 20°F( — 7°C). Maintenance Synthetic Oil You may use a synthetic motor oil if it meets the same requirements given for conventional motor oil; energy conserving, a service classification of SJ, and the proper weight as shown on the chart. When using synthetic oil, you must follow the oil and filter change intervals given in the maintenance schedule. Additives Your Honda does not need any oil additives. Purchasing additives for the engine or transmission will not increase your vehicle's performance or longevity. It only increases the cost of operating your vehicle. Main MenuTable of ContentsstChanging the Oil and Filter Always change the oil and filter according to the time and distance (miles/kilometers) recommenda- tions in the maintenance schedule. The oil and filter collect contami- nants that can damage your engine if they are not removed regularly. Changing the oil and filter requires special tools and access from underneath the vehicle. The vehicle should be raised on a service station- type hydraulic lift for this service. Unless you have the knowledge and proper equipment, you should have this maintenance done by a skilled mechanic. 1. Run the engine until it reaches normal operating temperature, then shut it off. OIL DRAIN BOLT WASHER 2. Open the hood and remove the engine oil fill cap. Remove the oil drain bolt and washer from the bottom of the engine. Drain the oil into an appropriate container. Engine Oil Type SH OIL FILTER 3. Remove the oil filter and let the remaining oil drain. A special wrench (available from your Honda dealer) is required to remove the filter. CONTINUED Maintenance Main MenuTable of ContentsstEngine Oil Except Type SH OIL FILTER 4. Install a new oil filter according to instructions that come with it. Maintenance 9. Turn off the engine, let it sit for several minutes, then check the oil level. If necessary, add oil to bring the level to the upper mark on the dipstick. NOTICE Improper disposal of engine oil can be harmful to the environment. If yon change your own oil, please dispose of the used oil properly. Put it in a sealed container and take it to a recycling center. Do not discard it in a trash bin or dump it on the ground. 5. Put a new washer on the drain bolt, then reinstall the drain bolt. Tighten it to: 33 Ibf.ft (44 N.m , 4.5 kgf.m) 6. Refill the engine with the recom- mended oil. Engine oil change capacity (including filter): 5.1 US qt(4.8 l ,4.2 Imp qt) 7. Replace the engine oil fill cap. Start the engine. The oil pressure indicator light should go out within five seconds. If it does not, turn off the engine and reinspect your work. 8. Let the engine run for several minutes and check the drain bolt and oil filter for leaks. Main MenuTable of ContentsstCooling System Always use Genuine Honda antifreeze/coolant. If it is not available, you may use another major-brand non-silicate coolant as a temporary replacement. Make sure it is a high-quality coolant recommended for aluminum engines. However, continued use of any non- Honda coolant can result in corrosion, causing the cooling system to malfunction or fail. Have the cooling system flushed and refilled with Honda antifreeze/ coolant as soon as possible. If the reserve tank is completely empty, you should also check the coolant level in the radiator. Removing the radiator cap while the engine is hot can cause the coolant to spray out, seriously scalding you. Always let the engine and radiator cool down before removing the radiator cap. Adding Engine Coolant RESERVE TANK If the coolant level in the reserve tank is at or below the MIN line, add coolant to bring it up to the MAX line. Inspect the cooling system for leaks. This coolant should always be a mixture of 50 percent antifreeze and 50 percent water. Never add straight antifreeze or plain water. CONTINUED Maintenance Main MenuTable of Contentsst3. Remove the radiator cap by pushing down and turning counterclockwise. 4. The coolant level should be up to the base of the filler neck. Add coolant if it is low. 5. Put the radiator cap back on. Tighten it fully. RESERVE TANK 6. Pour coolant into the reserve tank. Fill it to halfway between the MAX and MIN marks. Put the cap back on the reserve tank. Cooling System RADIATOR CAP 1. Make sure the engine and radiator are cool. 2. Turn the radiator cap counter- clockwise, without pressing down on it, until it stops. This relieves any pressure remaining in the cooling system. Maintenance Main MenuTable of ContentsstDo not add any rust inhibitors or other additives to your vehicle's cooling system. They may not be compatible with the coolant or engine components. Replacing Engine Coolant The cooling system should be completely drained and refilled with new coolant according to the time and distance recommendations in the maintenance schedule. Only use Genuine Honda antifreeze/coolant. Draining the coolant requires access to the underside of the vehicle. Unless you have the tools and knowledge, you should have this maintenance done by a skilled mechanic. Cooling System DRAIN PLUG 1. Slide the heater temperature control lever to maximum heat. Open the hood. Make sure the engine and radiator are cool to the touch. 2. Remove the radiator cap. Type SH 3. Loosen the drain plug on the bottom of the radiator. The coolant will come out through the hole in the splash cover.

Tighten it again when coolant comes out in a steady stream with no bubbles. 10. Turn off the engine. Check the level in the radiator, add coolant if needed. Install the radiator cap, and tighten it fully. 9. Refill the radiator to the base of the filler neck. Start the engine and let it run until it warms up (the radiator cooling fan comes on at least twice). 11. Fill the reserve tank to the MAX mark. Install the reserve tank cap. Maintenance Main MenuTable of ContentsstThe windshield washer reservoir is located behind the driver's side headlight. Check the reservoir's fluid level by removing the cap and looking at the float. It should be up to the top of the neck. If the float is at the bottom of the neck, the reservoir is nearly empty. Fill the reservoir with a good-quality windshield washer fluid. This increases the cleaning capability and prevents freezing in cold weather. NOTICE Do not use engine antifreeze or a vinegar/water solution in the windshield washer reservoir. Antifreeze can damage your vehicle's paint, while a vinegar/water solution can damage the windshield washer pump. Use only commercially-available windshield washer fluid. Windshield Washers FLOAT Check the level in the windshield washer reservoir at least monthly during normal usage. In bad weather, when you use the washers often, check the level every time you stop for fuel. Maintenance Main MenuTable of ContentsstAutomatic Transmission DIPSTICK Check the fluid level with the engine at normal operating temperature. 1. Park the vehicle on level ground. Shut off the engine. 2. Remove the dipstick (yellow loop) from the transmission and wipe it with a clean cloth. Transmission Fluid 5. If the level is below the lower mark, add fluid into the filler hole to bring it to the upper mark. Always use Honda Premium Formula Automatic Transmission Fluid (ATF). If it is not available, you may use a DEXRON® III automatic transmission fluid as a temporary replacement. However, continued use can affect shift quality. Have the transmission drained and refilled with Honda ATF as soon as it is convenient. DIPSTICK UPPER MARK LOWER MARK 3. Insert the dipstick all the way into the transmission securely as shown in the illustration. 6. Insert the dipstick all the way back into the transmission securely as shown in the illustration. 4. Remove the dipstick and check the fluid level. It should be between the upper and lower marks. The transmission should be drained and refilled with new fluid according to the time and distance recommen- dations in the maintenance schedule. Maintenance Main MenuTable of ContentsstCheck the fluid level with the transmission at normal operating temperature and the vehicle sitting on level ground. Remove the transmission filler bolt and carefully feel inside the bolt hole with your finger. The fluid level should be up to the edge of the bolt hole. If it is not, add Genuine Honda Manual Transmission Fluid (MTF) until it starts to run out of the hole. Reinstall the filler bolt and tighten it securely. If Honda MTF is not available, you may use an API service SG, SH or SJ grade motor oil with a viscosity of SAE 10W-30 or 10W-40 as a temporary replacement. An SG grade is preferred, but an SH or SJ grade may be used if SG is not available. However, motor oil does not contain the proper additives and continued use can cause stiffer shifting. Replace as soon as convenient. The transmission should be drained and refilled with new fluid according to the time and distance recommen- dations in the maintenance schedule. Transmission Fluid 5-speed Manual Transmission FILLER BOLT Correct level Maintenance Main MenuTable of ContentsstCheck the fluid level in the reser- voirs monthly. There are up to two reservoirs, depending on model. They are: Brake fluid reservoir (all models) Clutch fluid reservoir (manual transmission only) The brake fluid in the brake system should be replaced according to the time and distance recommendations in the maintenance schedule. Always use Genuine Honda DOT 3 brake fluid. If it is not available, you should use only DOT 3 or DOT 4 fluid, from a sealed container, as a temporary replacement. However, the use of any non-Honda brake fluid can cause corrosion and decrease the life of the system. Have the brake system flushed and refilled with Honda DOT 3 brake fluid as soon as possible. Brake fluid marked DOT 5 is not compatible with your vehicle's braking system and can cause extensive damage. Brake and Clutch Fluid Brake System MAX MIN The fluid level should be between the MIN and MAX marks on the side of the reservoir. If the level is at or below the MIN mark, your brake system needs attention. Have the brake system inspected for leaks or worn brake pads. Maintenance Main MenuTable of ContentsstBrake and Clutch Fluid, Power Steering Clutch System Power Steering UPPER LEVEL LOWER LEVEL Check the level when the engine is cold. Look at the side of the reservoir. The fluid should be between the UPPER LEVEL and LOWER LEVEL. If it is below the LOWER LEVEL, add power steering fluid to the UPPER LEVEL. MAX MIN The fluid should be between the MIN and MAX marks on the side of the reservoir. If it is not, add brake fluid to bring it up to that level. Use the same fluid specified for the brake system. Low fluid level can indicate a leak in the clutch system. Have this system inspected as soon as possible. Maintenance Always use Genuine Honda Power Steering Fluid. If it is not available, you may use another power steering fluid as an emergency replacement. However, continued use can cause increased wear and poor steering in cold weather. Have the power steering system flushed and refilled with Honda PSF as soon as possible. A low power steering fluid level can indicate a leak in the system. Check the fluid level frequently and have the system inspected as soon as possible. NOTICE Turning the steering wheel to full left or right lock and holding it there can damage the power steering pump. Main MenuTable of ContentsstThe air cleaner element should be cleaned or replaced according to the time and distance recommendations in the maintenance schedule. Cleaning (Severe Conditions) Clean the air cleaner element by blowing compressed air through it in the opposite direction to normal air flow. If you do not have access to compressed air (such as a service station), ask your Honda dealer to do this service. Follow the replacement procedure for removal and reinstallation. Air Cleaner Element Replacement CLAMPS The air cleaner element is inside the air cleaner housing on the passenger's side of the engine compartment. To replace it: 1. Unsnap the four hold-down clamps and remove the air cleaner housing cover. AIR CLEANER ELEMENT 2. Remove the old air cleaner element. Clean the inside of the air cleaner housing with a damp rag. 3.

Maintenance Main MenuTable of ContentsstSpark Plugs, Battery Specifications: NGK: DENSO: Spark Plug Gap: PZFR6F-11 PKJ20CR-L11 0.043 in (1.1mm Battery Check the condition of your vehicle's battery monthly. You should check the color of the test indicator window, and for corrosion on the terminals. TEST INDICATOR WINDOW Check the battery condition by looking at the test indicator window on the battery. The label on the battery explains the test indicator's colors. Maintenance Main MenuTable of ContentsstBattery The battery gives off explosive hydrogen gas during normal operation. A spark or flame can cause the battery to explode with enough force to kill or seriously hurt you. Wear protective clothing and a face shield, or have a skilled mechanic do the battery maintenance. If the terminals are severely cor- roded, clean them with baking soda and water. Then use a wrench to loosen and remove the cables from the terminals. Always disconnect the negative ( —) cable first and recon- nect it last. Clean the battery termi- nals with a terminal cleaning tool or wire brush. Reconnect and tighten the cables, then coat the terminals with grease. If you need to connect the battery to a charger, disconnect both cables to prevent damage to the vehicle's electrical system. CONTINUED Maintenance Check the battery terminals for corrosion (a white or yellowish powder). To remove it, cover the terminals with a solution of baking soda and water. It will bubble up and turn brown. When this stops, wash it off with plain water. Dry off the battery with a cloth or paper towel. Coat the terminals with grease to help prevent future corrosion. Main MenuTable of ContentsstBattery If your vehicle's battery is discon- nected or goes dead, the audio system will disable itself. The next time you turn on the radio you will see "Code" in the frequency display. Use the Preset buttons to enter the five-digit code (see page 117). NOTICE Charging the battery with the cables connected can seriously damage your vehicle's electronic controls. Detach the battery cables before connecting the battery to a charger. Maintenance Main MenuTable of ContentsstCheck the condition of the wiper blades at least every six months. Look for signs of cracking in the rubber, or areas that are getting hard. Replace the blades if you find these signs, or they leave streaks and unwiped areas when used. WIPER ARMS Wiper Blades LOCK TAB To replace the blade: 1. Raise the wiper arm off the windshield. Raise the driver's side first, then the passenger's side. 2. Disconnect the blade assembly from the wiper arm by pushing in the lock tab. Hold it in while you push the blade assembly toward the base of the arm. CONTINUED Maintenance Main MenuTable of Contentsst5. Slide the new wiper blade into the holder until the tabs lock. 6.

Wiper Blades BLADE BLADE 3. Remove the blade from its holder by grasping the tabbed end of the blade. Pull firmly until the tabs come out of the holder. REINFORCEMENT 4. Examine the new wiper blades. If they have no plastic or metal rein- forcement along the back edge, remove the metal reinforcement strips from the old wiper blade and install them in the slots along the edge of the new blade. Maintenance Main MenuTable of ContentsstAir Conditioning System Your vehicle's air conditioning is a sealed system. Any major mainte- nance, such as recharging, should be done by a qualified mechanic. You can do a couple of things to make sure the air conditioning works efficiently. Periodically check the engine's radiator and air conditioning condenser for leaves, insects, and dirt stuck to the front surface. These block the air flow and reduce cooling efficiency. Use a light spray from a hose or a soft brush to remove them. If the air conditioning does not get as cold as before, have your dealer check the system. Recharge the system with Refrigerant HFC-134a (R-134a). (See Specifications on page 255.) AIR CONDITIONING CONDENSER NOTICE The condenser and radiator fins bend easily. Only use a low-pressure spray or soft-bristle brush to clean them. Run the air conditioning at least once a week during the cold weather months. Run it for at least ten minutes while you are driving at a steady speed with the engine at normal operating temperature. This circulates the lubricating oil con- tained in the refrigerant. NOTICE Whenever you have the air conditioning system serviced, make sure the service facility uses a refrigerant recycling system. This system captures the refrigerant for reuse. Releasing refrigerant into the atmosphere can damage the environment. Maintenance Main MenuTable of ContentsstThe belts should have the following "play" or deflection. Alternator belt: 0.37-0.49 in (9.5-12.5 mm) Power steering belt: 0.53-0.65 in (13.5-16.5 mm) If you see signs of wear or looseness, have your dealer adjust or replace the belts. Timing Belt The timing belt and balancer belt should normally be replaced at the intervals shown in the maintenance schedule. Replace these belts at 60,000 miles (U.S.) or 100,000 km (Canada) if you regularly drive your vehicle in one or more of these conditions: In very high temperatures (over110°F,43°C). In very low temperatures (under — 20°F, — 29°C). Drive Belts, Timing Belt Drive Belts POWER STEERING BELT ALTERNATOR BELT Check the condition of the two drive belts. Examine the edges of each belt for cracks or fraying. Check the tension of each belt by pushing on it with your thumb midway between the pulleys. Maintenance Main MenuTable of ContentsstTo safely operate your vehicle, your tires must be the proper type and size, in good condition with adequate tread, and correctly inflated. The following pages give more detailed information on how and when to check air pressure, how to inspect your tires for damage and wear, and what to do when your tires need to be replaced. Inflation Keeping the tires properly inflated provides the best combination of handling, tread life and riding comfort. Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Overinflated tires can make your vehicle ride more harshly, are more prone to damage from road hazards, and wear unevenly. Using tires that are excessively worn or improperly inflated can cause a crash in which you can be seriously hurt or killed. We recommend that you visually check your tires every day. If you think a tire might be low, check it immediately with a tire gauge. Follow all instructions in this owner's manual regarding tire inflation and maintenance. Use a gauge to measure the air pressure at least once a month. Even tires that are in good condition may lose one to two psi (10 to 20 kPa, 0.1 to 0.2 kgf/cm2) per month. Remember to check the spare tire at the same time you check all the other tires. Tires Check the pressure in the tires when they are cold. This means the vehicle has been parked for at least three hours. If you have to drive the vehicle before checking the tire pressure, the tires can still be considered "cold" if you drive less than 1 mile (1.6km). If you check the pressure when the tires are hot (the vehicle has been driven several miles), you will see readings 4 to 6 psi (30 to 40 kPa, 0.3 to 0.4 kgf/cm2) higher than the cold reading. This is normal. Do not let air out to match the specified cold pressure. The tire will be underinflated. You should get your own tire pressure gauge and use it whenever you check your tire pressures. This will make it easier for you to tell if a pressure loss is due to a tire problem and not due to a variation between gauges. CONTINUED Maintenance Main MenuTable of ContentsstTubeless tires have some ability to self-seal if they are punctured. However, because leakage is often very slow, you should look closely for punctures if a tire starts losing pressure. Inspection Every time you check inflation, you should also examine the tires for damage, foreign objects, and wear. You should look for: Bumps or bulges in the tread or side of the tire.

Tires Recommended Tire Pressures for Normal Driving The following chart shows the recommended cold tire pressures for most normal driving conditions and speeds. Tire pressures for high speed driving are shown on page 257. The compact spare tire pressure is: 60 psi (420 kPa , 4.2 kgf/cm2) These pressures are also given on the tire information label on the driver's doorjamb. Maintenance Main MenuTable of ContentsstINDICATOR LOCATION MARKS TREAD WEAR INDICATORS Your vehicle's tires have wear indica- tors molded into the tread. When the tread wears down to that point, you will see a 1/2 inch (12.7 mm) wide band running across the tread. This shows there is less than 1/16 inch (1.6 mm) of tread left on the tire. A tire that is this worn gives very little traction on wet roads. You should replace the tire if you can see the tread wear indicator in three or more places around the 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. The tires were properly balanced by the factory. They may need to be rebalanced at some time before they are worn out. Have your dealer check the tires if you feel a consis- tent vibration while driving. A tire should always be rebalanced if it is removed from the wheel for repair. Make sure the installer balances the wheels when you have new tires installed. This increases riding comfort and tire life. Your vehicle's original tires were dynamic or "spin" balanced at the factory. For best results, have the installer perform a dynamic balance. Tires NOTICE Improper wheel weights can damage your vehicle's aluminum wheels. Use only Genuine Honda wheel weights for balancing. Maintenance Main MenuTable of ContentsstTires Tire Rotation Front Front (For Non-directional Tires and Wheels) (For Directional Tires and Wheels) To help increase tire life and distribute wear more evenly, you should have the tires rotated every 7,500 miles (12,000 km). Move the tires to the positions shown in the chart each time they are rotated. Maintenance When shopping for replacement tires, you may find that some tires are "directional." This means they are designed to rotate only in one direction. If you use directional tires, they should be rotated only front-to-back. Replacing Tires and Wheels The tires that came with your vehicle were selected to match the performance capabilities of the vehicle while providing the best combination of handling, ride comfort, and long life. You should replace them with radial tires of the same size, load range, speed rating, and maximum cold tire pressure rating (as shown on the tire's sidewall). Mixing radial and bias-ply tires on your vehicle can reduce its braking ability, traction, and steering accuracy. Installing improper tires on your vehicle can affect handling and stability. This can cause a crash in which you can be seriously hurt or killed. Always use the size and type of tires recommended in this owner's manual. It is best to replace all four tires at the same time. If that is not possible or necessary, then replace the two front tires or the two rear tires as a pair. Replacing just one tire can seriously affect your vehicle's han- dling. Main MenuTable of ContentsstTires The ABS works by comparing the speed of the wheels. When replacing tires, use the same size originally supplied with the vehicle. Tire size and construction can affect wheel speed and may cause the system to work inconsistently. Wheels and Tires Wheel: 16x61/2 JJ Tire: 205/50R1687V If you ever need to replace a wheel, make sure the wheel's specifications match those of the original wheel that came on your vehicle. Re- placement wheels are available at your Honda dealer. See Tire Information on page 256 for additional information about tire and wheel size designations. See page 257 for information about DOT Tire Quality Grading. Winter Driving Tires that are marked "M + S" or "All Season" on the sidewall have an all-weather tread design. They should be suitable for most winter driving conditions. Tires without these markings are designed for optimum traction in dry conditions. They may not provide adequate performance in winter driving. For the best performance in snowy or icy conditions, you should install snow tires or tire chains. They may be required by local laws under certain conditions. CONTINUED Maintenance Main MenuTable of ContentsstNOTICE Chains of the wrong size or that are improperly installed can damage your vehicle's brake lines, suspension, body, and wheels. Stop driving if you hear the chains hitting any part of the vehicle. Tires Snow Tires If you mount snow tires on your Honda, make sure they are radial tires of the same size and load range as the original tires. Mount snow tires on all four wheels to balance your vehicle's handling in all weather conditions. Keep in mind the traction provided by snow tires on dry roads may not be as high as your vehicle's original equipment tires. You should drive cautiously even when the roads are clear. Check with the tire dealer for maximum speed recommenda- tions. Maintenance Tire Chains Mount snow chains on your vehicle when warranted by driving condi- tions or required by local laws. Make sure the chains are the correct size for your tires. Install them only on the front tires. If metal chains are used, they must be SAE class "S". Cable type traction devices can also be used. When installing chains, follow the manufacturer's instructions and mount them as tightly as you can. Drive slowly with chains installed. If you hear the chains contacting the body or chassis, stop and investigate. Make sure the chains are installed tightly, and that they are not contacting the brake lines or suspension. Remove the chains as soon as you begin driving on cleared roads.

Maintenance Main MenuTable of ContentsstIf you need to park your vehicle for an extended period (more than one month), there are several things you should do to prepare it for storage. Proper preparation helps prevent deterioration and makes it easier to get your vehicle back on the road. If possible, store your vehicle indoors. Fill the fuel tank. Change the engine oil and filter (see page 175). Wash and dry the exterior completely. Clean the interior. Make sure the carpeting, floor mats, etc. are completely dry. Leave the parking brake off. Put the transmission in Reverse (5- speed manual) or Park (automatic). Storing Your Vehicle Block the rear wheels. If the vehicle is to be stored for a longer period, it should be supported on jackstands so the tires are off the ground. Leave one window open slightly (if the vehicle is being stored indoors). Disconnect the battery. Support the front wiper blade arms with a folded towel or rag so they do not touch the windshield. To minimize sticking, apply a silicone spray lubricant to all door and trunk seals. Also, apply a vehicle body wax to the painted surfaces that mate with the door and trunk seals. Cover the vehicle with a "breathable" vehicle cover, one made from a porous material such as cotton. Nonporous materials, such as plastic sheeting, trap moisture, which can damage the paint. If possible, run the engine for a while periodically (preferably once a month). If you store your vehicle for 12 months or longer, have your Honda dealer perform the inspections called for in the 24 months/30,000 miles (48,000 km) maintenance schedule (Normal Conditions) as soon as you take it out of storage (see page 164). The replacements called for in the maintenance schedule are not needed unless the vehicle has actually reached that time or mileage.
