Automatic Transmission Whenever you move the shift lever, slide it along the guide on the console. You cannot shift out of Park with the brake pedal depressed when the ignition switch is in LOCK (0) or ACCESSORY (I). CONTINUED Driving Main MenuTable of ContentsstAutomatic Transmission Park (P) — This position mechani- cally locks the transmission. Use Park whenever you are turning off or starting the engine. To shift out of Park, you must press on the brake pedal and have your foot off the accelerator pedal. Move the shift lever to the right to shift out of the Park position. If you have done all of the above and still cannot move the lever out of Park, see Shift Lock Release on page 143. Driving Reverse (R) — To shift to Reverse from Park, see the explanation under Park. To shift to Reverse from Neutral, come to a complete stop and then shift. Your car has a reverse lockout so you cannot accidentally shift to Reverse from Neutral or any other driving position when the vehicle speed exceeds 7 — 9 mph (12 — 14 km/h). If you cannot shift to Reverse when the car is stopped, press the brake pedal and slowly shift to Neutral then to Reverse. If there is a problem in the reverse lockout system, or your vehicle's battery is disconnected or goes dead, you cannot shift to Reverse. In this case, use the procedure of Shift Lock Release (see page 143). To avoid transmission damage, come to a complete stop before shifting into Park. The shift lever must be in Park before you can remove the key from the ignition switch. Main MenuTable of ContentsstNeutral (N) — Use Neutral if you need to restart a stalled engine, or if it is necessary to stop briefly with the engine idling. Shift to Park posi- tion if you need to leave the vehicle for any reason. Press on the brake pe- dal when you are moving the shift lever from Neutral to another gear. Drive (D4) — Use this position for your normal driving. The transmis- sion automatically selects a suitable gear for your speed and acceleration. You may notice the transmission shifting up at higher speeds when the engine is cold. This helps the engine warm up faster. Automatic Transmission Sequential SportShift Mode With the shift lever in "D4" position, you can select the Sequential SportShift mode to shift gears; much like a manual transmission, but without a clutch pedal. the gear you selected while in the sequential sportshift mode. If you select the Sequential SportShift while the vehicle is stopped, the transmission automatically selects first gear and the display shows / 1 /. To enter the Sequential SportShift mode, slide the shift lever further to the left. To return to "D4", slide the shift lever to the right. In the Sequential SportShift mode, each time you push forward on the shift lever, the transmission shifts to a higher gear. Pull back on the lever to downshift. The number of the gear selected is displayed next to the "D4" indicator (see page 136). If you slide the shift lever from "D4" to the Sequential SportShift mode, the display shows the selected gear. If you selected "4", you will see / 4/ next to "D4" in the display. The Shift Lever Position Indicator will show Upshift Downshift CONTINUED Driving Main MenuTable of ContentsstAutomatic Transmission When you accelerate away from a stop, the transmission will be in first gear. The transmission will not automatically upshift. Watch the tachometer and upshift manually before the engine reaches redline. Driving The transmission remains in the selected gear (4, 3, 2, or 1). There is no automatic downshift when you push the accelerator pedal to the floor. The transmission may automatically downshift from fourth gear to third gear under the following conditions: Downshifting gives you more power when climbing or provides engine braking when going down a steep hill. The transmission will also shift automatically as the vehicle comes to a complete stop. It will downshift to first gear when the vehicle speed is under 6 mph (10 km/h). The vehicle speeds drops below 20 mph (32km/h). If you drive uphill between 20 — 31mph(32 — 50km/h). If you press the brake pedal as you drive downhill. If you try to manually downshift at a speed that would cause the engine to exceed the redline in a lower gear, the transmission will not downshift. If you try to downshift from fourth gear to third gear, the gear indicator will flash / 3/ several times, then return to / 4 /; if you try to downshift from third gear to second gear, the gear indicator will flash / 2/ several times, then return to third gear. Main MenuTable of ContentsstThe table shows the speed ranges for upshifting and downshifting. If the vehicle speeds slows to below the redline of the selected lower gear position while the indicator is flashing, the transmission downshifts and the display shows the selected lower gear. If the transmission temperature is below 14°F(— 10°C), you may not be able to use the Sequential SportShift mode. Automatic Transmission Drive (D3) — This position is similar to D4, except only the first three gears are selected. Use D3 when towing a trailer in hilly terrain, or to provide engine braking when going down a steep hill. D3 can also keep the transmission from cycling between third and fourth gears in stop-and-go driving. For faster acceleration when in D3 or D4, you can get the transmission to automatically downshift by pushing the accelerator pedal to the floor. The transmission will shift down one or two gears, depending on your speed. CONTINUED Driving Main MenuTable of ContentsstAutomatic Transmission Second (2) — This position locks the transmission in second gear. It does not downshift to first gear when you come to a stop. Second gives you more power when climbing, and increased engine braking when going down steep hills. Use second gear when starting out on a slippery surface or in deep snow. It will help reduce wheelspin. First (1) With the lever in this position, the transmission locks in First gear. If you shift into First position when the vehicle speed exceeds 31 mph (50 km/h), the transmission shifts into Second gear first to avoid the application of the sudden engine brake. Maximum Allowable Speeds The speeds in this table are the maximum allowable speeds in each position. If you exceed these speeds, the engine speed will enter into the tachometer's red zone. If this occurs, you will feel the engine cut in and out. This is caused by a limiter in the engine's computer controls. The engine will run normally when you reduce the RPM below the red zone. Before downshifting, make sure the vehicle will not exceed the maximum allowable speed in the chart in the lower gear to avoid engine damage. Driving Main MenuTable of ContentsstShift Lock Release This allows you to move the shift lever out of Park if the normal method of pushing on the brake pedal does not work. This procedure also releases the Reverse Lockout. 1. Set the Parking brake. 2. Make sure the key is in the ignition switch OFF (0) position. To release the Reverse Lockout, make sure the key is in the ACCESSORY (I) position. 3. Put a cloth on the edge of the shift lock release slot cover next to the shift lever. Use a small flat-tipped screwdriver or small metal plate (neither are included in the tool kit) to remove the cover. Carefully pry off the edge of the cover. Automatic Transmission SHIFT LOCK RELEASE SLOT COVER 4. Insert a screwdriver in the shift lock release slot. 5. Push down on the screwdriver and move the shift lever out of Park to Neutral. To release the Reverse Lockout, move the shift lever from Neutral to Reverse, then Park. 6. Remove the screwdriver from the shift lock release slot, then install a new cover. Depress the brake pedal and restart the engine. If you need to use the Shift Lock Release, it means your vehicle is developing a problem. Have the vehicle checked by your Honda dealer. Driving Main MenuTable of ContentsstIf the vehicle is facing uphill, turn the front wheels away from the curb. If you have a manual transmission, put it in first gear. If the vehicle is facing downhill, turn the front wheels toward the curb. If you have a manual transmission, put it in reverse gear. Make sure the parking brake is fully released before driving away. Driving with the parking brake partially set can overheat or damage the rear brakes. Parking Tips Make sure the moonroof and the windows are closed. Turn off the lights. Place any packages, valuables, etc., in the trunk or take them with you. Lock the doors. Never park over dry leaves, tall grass, or other flammable materials. The three way catalytic converter gets very hot, and could cause these materials to catch on fire. Parking Always use the parking brake when you park your vehicle. The indicator on the instrument panel shows that the parking brake is not fully released; it does not indicate that the parking brake is firmly set. Make sure the parking brake is set firmly or your vehicle may roll if it is parked on an incline. If your vehicle has an automatic transmission, set the parking brake before you put the transmission in Park. This keeps the vehicle from moving and putting pressure on the parking mechanism in the transmission — making it easier to move the shift lever out of Park when you want to drive away. Driving Main MenuTable of ContentsstThe Braking System Your Honda is equipped with disc brakes at all four wheels. A power assist helps reduce the effort needed on the brake pedal. The ABS helps you retain steering control when braking very hard. Put your foot on the brake pedal only when you intend to brake. Resting your foot on the pedal keeps the brakes applied lightly, causing them to build up heat. Heat build-up can reduce how well your brakes work. It also keeps your brake lights on all the time, confusing drivers behind you. Constant application of the brakes when going down a long hill builds up heat and reduces their effective- ness. Use the engine to assist the brakes by downshifting to a lower gear and taking your foot off the accelerator pedal. Check your brakes after driving through deep water. Apply the brakes moderately to see if they feel normal. If not, apply them gently and frequently until they do. Since a longer distance is needed to stop with wet brakes, be extra cautious and alert in your driving. Brake Wear Indicators All four brakes have audible brake wear indicators. When the brake pads need replacing, you will hear a distinctive metallic "screeching" sound when you apply the brakes. If you do not have the brake pads replaced, they will begin screeching all the time. Your brakes may sometimes squeal or squeak when you apply them lightly. Do not confuse this with the brake wear indicators. They make a very audible "screeching." Driving Main MenuTable of ContentsstThe Braking System Brake System Design The hydraulic system that operates the brakes has two separate circuits. Each circuit works diagonally across the vehicle (the left-front brake is connected with the right-rear brake, etc.). If one circuit should develop a problem, you will still have braking at two wheels. Front Driving Anti-lock Brakes Your vehicle has an Anti-lock Brake System (ABS) as standard equipment. ABS helps to prevent the wheels from locking up and skidding during hard braking, allowing you to retain steering control. When the front tires skid, you lose steering control; the vehicle continues straight ahead even though you turn the steering wheel. The ABS helps to prevent lock-up and helps you retain steering control by pumping the brakes rapidly; much faster than a person can do it. You should never pump the brake pedal, this defeats the purpose of the ABS. Let the ABS work for you by always keeping firm, steady pressure on the brake pedal as you steer away from the hazard. This is sometimes referred to as "stomp and steer." You will feel a pulsation in the brake pedal when the ABS activates, and you may hear some noise. This is normal, it is the ABS rapidly pumping the brakes. Activation varies with the amount of traction your tires have. On dry pavement, you will need to press on the brake pedal very hard before you activate the ABS. However, you may feel the ABS activate immediately if you are trying to stop on snow or ice. Main MenuTable of ContentsstThe Braking System Important Safety Reminders ABS does not reduce the time or distance it takes to stop the vehicle, it only helps with steering control during braking. You should always maintain a safe following distance from other vehicles. ABS will not prevent a skid that results from changing direction abruptly, such as trying to take a corner too fast or making a sudden lane change. Always drive at a safe, prudent speed for the road and weather conditions. A vehicle with ABS may require a longer distance to stop on loose or uneven surfaces, such as gravel or snow, than a vehicle without anti- lock. Slow down and allow a greater distance between vehicles under those conditions. ABS cannot prevent a loss of stability. Always steer moderately when you are braking hard. Severe or sharp steering wheel movement can still cause your vehicle to veer into oncoming traffic or off the road. CONTINUED Driving Main MenuTable of ContentsstIf anything goes wrong, the ABS indicator on the instrument panel comes on (see page 54). This means the anti-lock function of the braking system has shut down. The brakes still work like a conventional system without anti-lock, providing normal stopping ability. You should have the dealer inspect your vehicle as soon as possible. The Braking System ABS Indicator ABS INDICATOR* * U.S. indicator shown The ABS is self-checking. It also checks itself whenever you use the brakes. Driving Main MenuTable of ContentsstType SH only Your Honda is equipped with an Active Torque Transfer System (ATTS). Under certain driving conditions, the ATTS enhances the vehicle's cornering performance by transferring some torque between the inside and outside front wheels during a turn. Based on steering wheel turn angle, lateral acceleration, and engine power, the ATTS regulates the driving force to each drive wheel through an electronically-controlled hydraulic system and two sets of clutches and gears. Active Torque Transfer System Important Safety Information The ATTS cannot prevent skidding if you enter a corner too fast. It has almost no effect on braking and vehicle speed. It is still your responsibility to drive at reasonable speeds and to leave a sufficient margin of safety. ATTS Indicator ATTS INDICATOR The Active Torque Transfer System (ATTS) is self-checking. If a problem is detected in the system, the ATTS indicator on the instrument panel comes on. If this happens, take the vehicle to your dealer to have it checked. With the indicator on, your vehicle will corner normally, but you will not have active torque transfer. Driving Main MenuTable of ContentsstDriving in Bad Weather Rain, fog, and snow conditions re- quire a different driving technique because of reduced traction and visibility. Keep your vehicle well- maintained and exercise greater caution when you need to drive in bad weather. The cruise control should not be used in these condi- tions. Driving Visibility — Being able to see clearly in all directions and being visible to other drivers are important in all weather conditions. This is more difficult in bad weather. To be seen more clearly during daylight hours, turn on your headlights. Inspect your windshield wipers and washers frequently. Keep the wind- shield washer reservoir full of the proper fluid. Have the windshield wiper blades replaced if they start to streak the windshield or leave parts unwiped. Use the defrosters and air conditioning to keep the windows from fogging up on the inside (see page 98). Driving Technique — Always drive slower than you would in dry weather. It takes your vehicle longer to react, even in conditions that may seem just barely damp. Apply smooth, even pressure to all the controls. Abrupt steering wheel movements or sudden, hard appli- cation of the brakes can cause loss of control in wet weather. Be extra cautious for the first few miles (kilometers) of driving while you adjust to the change in driving conditions. This is especially true in snow. A person can forget some snow-driving techniques during the summer months. Practice is needed to relearn those skills. Exercise extra caution when driving in rain after a long dry spell. After months of dry weather, the first rains bring oil to the surface of the roadway, making it slippery. Main MenuTable of ContentsstTraction — Check your tires frequently for wear and proper pressure. Both are important in preventing "hydroplaning" (loss of traction on a wet surface). In the winter, mount snow tires on all four wheels for the best handling. Watch road conditions carefully, they can change from moment to moment. Wet leaves can be as slip- pery as ice. "Clear" roads can have patches of ice. Driving conditions can be very hazardous when the outside temperature is near freezing. The road surface can become covered with areas of water puddles mixed with areas of ice, so your traction can change without warning. Be careful when downshifting. If traction is low, you can lock up the drive wheels for a moment and cause a skid. Be very cautious when passing, or being passed by other vehicles. The spray from large vehicles reduces your visibility, and the wind buffeting can cause you to lose control. Driving in Bad Weather Driving Main MenuTable of ContentsstTowing a Trailer Your Honda is designed primarily to carry passengers and their cargo. You can use it to tow a trailer if you carefully observe some general rules. Driving The total weight of the trailer and everything loaded in it must not exceed 1,000 Ibs (450 kg). The "tongue load" should never exceed 110 Ibs (50 kg). This is the amount of weight the trailer puts on the hitch when it is fully-loaded. As a rule of thumb, the tongue load should be 10 percent of the total trailer package. For example, if the trailer and its load weigh 500 Ibs (225 kg), the tongue load should be 50 Ibs (22.5 kg). Adjust the trailer's cargo to change the tongue load. Start by putting approximately 60 percent of the cargo toward the front and 40 percent toward the rear. Never load the trailer so the back is heavier than the front. This takes weight off your vehicle's rear axle and reduces traction. The combined weight of the vehicle, all passengers and their luggage, and tongue load must not exceed the Gross Vehicle Weight Rating. The GVWR is printed on the Certification label attached to the driver's doorjamb (see page 252). The combined weight of the vehicle, all passengers and their luggage, and tongue load also must not exceed the Gross Axle Weight Rating. The GAWR is also shown on the Certification label. It tells you the maximum load for the front and rear axles. It is possible that your towing package does not exceed the GVWR but does exceed the GAWR. Improper trailer loading, and/or too much luggage in the trunk can overload the rear axle. Redistribute the load and check the axle weights again. Main MenuTable of ContentsstImproperly loading your vehicle and trailer can seriously affect its steering and braking performance, causing a crash in which you can be seriously injured. Check the loading of your vehicle and trailer carefully before starting to drive. The best way to confirm that your total towing package is within these specifications is to get it weighed. Load the vehicle and trailer as you normally would while towing, and take them to a public scale. Have them check the total weight and the weight at each axle, then compare the weights to the specifications. Towing a Trailer Trailer Hitches The trailer hitch must be the proper size and construction for your vehicle and the trailer you intend to tow. Consult with an expert before you purchase a trailer hitch, and have it installed by a qualified mechanic. The hitch should bolt to the underbody of the vehicle, and distribute the load over a wide area. Never use a hitch that mounts only to the rear bumper. The bumper is not designed to handle that type of load. NOTICE A trailer hitch that is not adequate for the size of the trailer, or a hitch that is improperly installed, can cause damage to the underside of your vehicle. Driving Main MenuTable of ContentsstTowing a Trailer Mirrors Many states and provinces have laws requiring special outside mirrors when you are towing a trailer. Check the laws in your area. You may want to install mirrors, even if they are not required. Hook up the trailer and see how much it obscures your ability to see behind you with the standard mirrors. If you cannot see directly behind you, or have a large blind spot next to the trailer or the vehicle, you should install mirrors intended for towing. Connecting the Trailer Most trailers that have a gross weight of 1,000 Ibs (450 kg) do not have their own braking system. If you are thinking of getting a trailer that does have brakes, make sure they are electrically-operated. There are no provisions in your vehicle to tap into its hydraulic braking system. Any attempt to attach the trailer's brakes to your vehicle's hydraulic system, no matter how successful it may seem, will lower braking effectiveness and create a potential hazard. Always use a safety chain when towing a trailer. Connect the safety chain securely at both ends. Make sure the chain crosses under the tongue so it will catch the trailer if it becomes unhitched. Leave enough slack in the chain so it can't bind in a sharp turn. Do not let it drag on the ground. Driving Main MenuTable of ContentsstGROUND (BLACK) BACK-UP LIGHT (GREEN/BLACK) LEFT TURN SIGNAL (GREEN/BLUE) RIGHT TURN SIGNAL (GREEN/YELLOW) BRAKE LIGHT (WHITE/BLACK) TAILLIGHT (RED/BLACK) Your vehicle has a trailer lighting connector in the trunk by the left tail- light. To use the connector, undo the fastener on the left side of the trunk lining. Refer to the drawing above for the wiring color code and pur- pose of each connector pin. Since the lighting and wiring can be different for various brands of trailers, have a technician who is familiar with your trailer modify its lighting plug. A converter may be required between the vehicle and trailer for the lights to work correctly. Towing a Trailer Before Starting Out As you are preparing to tow your trailer, do the following: Measure the trailer's tongue load. You can do this with a bathroom scale. Verify that the hitch and safety chain are securely fastened. Check the condition and air pressure of all tires on the trailer and your vehicle. Low tire pressure can seriously affect the handling. Also check the spare tire. With everything loaded and the trailer connected, check that the rear of the vehicle is not sagging. If so, redistribute the load in the vehicle. Check that all lights on the vehicle and trailer are working properly. Driving Main MenuTable of ContentsstTowing a Trailer Towing Safety Your vehicle will not stop as quickly with a trailer in tow. Leave extra distance between your vehicle and other vehicles. Avoid braking or turning suddenly. This could cause the trailer to jackknife or possibly turn over. The vehicle/trailer combination is more affected by crosswinds and buffeting. When being passed by a large vehicle, keep a constant speed and steer straight ahead. If there is too much wind buffeting, slow down to get out of the other vehicle's air turbulence. Keep in mind that your total vehicle is now much longer. Leave more room when making turns. The trailer tracks a smaller arc than the vehicle and can hit or run over something that the vehicle misses. When passing another vehicle, make sure the trailer is clear before changing lanes. Towing a trailer puts an extra load on your vehicle. You should have your vehicle serviced according to the "Maintenance Schedule under severe driving conditions" on page 166. This extra load is magnified when you are driving in hilly terrain. Watch the temperature gauge closely when climbing hills. If it gets near the hot area, turn off the air conditioning (if it is on). If this does not reduce the heat, it may be necessary to pull to the side of the road and wait for the engine to cool. If the automatic transmission shifts frequently between 3rd and 4th gears, put it in D3. This will help prevent the transmission from overheating. Help keep the brakes from overheating by shifting to a lower gear when going downhill. If you have to stop while going uphill, do not hold the vehicle in place by pressing on the accelerator. This can cause the automatic transmission to overheat. Use the parking brake or footbrake. Driving Main MenuTable of ContentsstWhen towing a trailer in the Sequential SportShift mode, select Third, Second, or First gear; depending on the vehicle speeds and road condition. Do not use Fourth gear. The recommended speed range for each gear position is shown in the table. When parking your vehicle and trailer, especially on a hill, be sure to follow all the normal precautions. Turn your front wheels into the curb, set the parking brake firmly, and put the transmission in 1st or Reverse (manual) or Park (automatic). In addition, place wheel chocks at each of the trailer's tires. Backing up with a trailer is difficult and takes practice. Drive slowly, make small movements with the steering wheel, and have someone stand outside to guide you. Grip the steering wheel on the bottom (rather than the usual position near the top). Move your hand to the left to get the trailer to move to the left, and right to move the trailer right.

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.

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.

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.

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.

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).
