Remove the clip by pushing the center of its top. 2. Remove the spare tire from the tire tray (see page 278 ). 284 SPACER CONE If you remove the spare tire from the pickup bed, reinstall the clip back into its hole. WING BOLT 3. Place the spare tire on the pickup bed as shown. 4. Place the spacer cone in the wheel hub, and secure the spare tire to the pickup bed with the wing bolt. 5. Store or secure the tool box. 2008 Ridgeline ０７／０４／２７　１４：１９：２７　３１ＳＪＣ６２０　０２９０ If the Engine Won’t Start Diagnosing why the engine won’t start falls into two areas, depending on what you hear when you turn the ignition switch to the START (III) position: You hear nothing, or almost nothing. The engine’s starter motor does not operate at all, or operates very slowly. You can hear the starter motor operating normally, or the starter motor sounds like it is spinning faster than normal, but the engine does not start up and run. Nothing Happens or the Starter Motor Operates Very Slowly When you turn the ignition switch to the START (III) position, you do not hear the normal noise of the engine trying to start. You may hear a clicking sound, a series of clicks, or nothing at all. Check these things: Check the transmission interlock. The transmission must be in Park or neutral or the starter will not operate. Turn the ignition switch to the ON (II) position. Turn on the headlights, and check their brightness. If the headlights are very dim or do not come on at all, the battery is discharged. See Jump Starting on page 286 Turn the ignition switch to the START (III) position. If the headlights do not dim, check the condition of the fuses. If the fuses are OK, there is probably something wrong with the electrical circuit for the ignition switch or starter motor. You will need a qualified technician to determine the problem. See Emergency Towing on page 298 If the headlights dim noticeably or go out when you try to start the engine, either the battery is discharged or the connections are corroded. Check the condition of the battery and terminal connec- tions (see page then try jump starting the vehicle from a booster battery (see page 286 ). You can 272 ). The Starter Operates Normally In this case, the starter motor’s speed sounds normal, or even faster than normal, when you turn the ignition switch to the START (III) position, but the engine does not run. Are you using a properly coded key? An improperly coded key will cause the immobilizer system indicator in the instrument panel to blink rapidly (see page ). 81 CONTINUED 285 2008 Ridgeline ０７／０４／２７　１４：１９：３６　３１ＳＪＣ６２０　０２９１ If the Engine Won’t Start, Jump Starting Jump Starting Although this seems like a simple procedure, you should take several precautions. A battery can explode if you do not follow the correct procedure, seriously injuring anyone nearby. Keep all sparks, open flames, and smoking materials away from the battery. You cannot start your vehicle by pushing or pulling it. ToJumpStartYourVehicle: 1. Open the hood, and check the physical condition of the battery. In very cold weather, check the condition of the electrolyte. If it seems slushy or frozen, do not try jump starting until it thaws. If a battery sits in extreme cold, the electrolyte inside can f reeze. Attempting to jump start with a f rozen battery can cause it to rupture. 2. Turn off all electrical accessories: heater, A/C, climate control, audio system, lights, etc. Put the transmission in Park, and set the parking brake. Are you using the proper starting Starting the procedure? Refer to Engine 200 on page Do you have fuel? Check the fuel gauge; the low fuel indicator may not be working. There may be an electrical problem, such as no power to the fuel pump. Check all the fuses (see page 293 ). If you find nothing wrong, you will need a qualified technician to find the problem. See Towing on page Emergency 298 286 2008 Ridgeline ０７／０４／２７　１４：１９：４４　３１ＳＪＣ６２０　０２９２ Jump Starting 5. 6. 7. If the booster battery is in another vehicle, have an assistant start that vehicle and run it at a fast idle. Start the vehicle. If the starter motor still operates slowly, check that the jumper cables have good metal-to-metal contact. Once your vehicle is running, disconnect the negative cable from your vehicle, then from the booster battery. Disconnect the positive cable from your vehicle, then from the booster battery. Keep the ends of the jumper cables away from each other and any metal on the vehicle until everything is disconnected. Otherwise, you may cause an electrical short. 287 4. − Connect the second jumper cable to the negative ( ) terminal on the booster battery. Connect the other end to the grounding strap as shown. Do not connect this jumper cable to any other part of the engine. BOOSTER BATTERY The numbers in the illustration show you the order to connect the jumper cables. 3. ＋ Connect one jumper cable to the positive ( ) terminal on your vehicle’s battery. Connect the other end to the positive ( terminal on the booster battery. ＋ 2008 Ridgeline ０７／０４／２７　１４：１９：５１　３１ＳＪＣ６２０　０２９３ If the Engine Overheats The pointer of your vehicle’s temperature gauge should stay in the midrange under most conditions. If it climbs to the red mark, you should determine the reason (hot day, driving up a steep hill, etc.). If the vehicle overheats, you should take immediate action. The only indication may be the temperature gauge climbing to or above the red mark. Or you may see steam or spray coming from under the hood. Driving with the temperature gauge pointer at the red mark can cause serious damage to the engine. 288 Steam and spray from an overheated engine can seriously scald you. Do not open the hood if steam is coming out. 1. 2. 3. Safely pull to the side of the road. Put the transmission in Park, and set the parking brake. Turn off all accessories, and turn on the hazard warning lights. If you see steam and/or spray coming from under the hood, turn off the engine. Wait until you see no more signs of steam or spray, then open the hood. If you do not see steam or spray, leave the engine running and watch the temperature gauge. If the high heat is due to overloading, the engine should start to cool down almost immediately. If it does, wait until the temperature gauge comes down to the midpoint, then continue driving. 2008 Ridgeline ０７／０４／２７　１４：１９：５９　３１ＳＪＣ６２０　０２９４ 4. If the temperature gauge stays at the red mark, turn off the engine. 5. 6. 7. Look for any obvious coolant leaks, such as a split radiator hose. Everything is still extremely hot, so use caution. If you find a leak, it must be repaired before you Emergency continue driving (see Towing ). 298 on page If you do not find an obvious leak, check the coolant level in the radiator reserve tank. Add coolant if the level is below the MIN mark. If there was no coolant in the reserve tank, you may need to add coolant to the radiator. Let the engine cool down until the pointer reaches the middle of the tempera- ture gauge, or lower, before check- ing 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. 8. Using gloves or a large heavy cloth, turn the radiator cap counterclockwise, without pushing down, to the first stop. After the pressure releases, push down on the cap, and turn it until it comes off. If the Engine Overheats 9. ’’). Add coolant to the Start the engine, and set the temperature to maximum heat (climate control to AUTO at ‘‘ radiator up to the base of the filler neck. If you do not have the proper coolant mixture available, you can add plain water. Remember to have the cooling system drained and refilled with the proper mixture as soon as you can. 10. 11. Put the radiator cap back on tightly. Run the engine, and check the temperature gauge. If it goes back to the red mark, the engine needs repair (see Towing on page Emergency 298 ). If the temperature stays normal, check the coolant level in the radiator reserve tank. If it has gone down, add coolant to the MAX mark. Put the cap back on tightly. 289 2008 Ridgeline ０７／０４／２７　１４：２０：０９　３１ＳＪＣ６２０　０２９５ Low Oil Pressure Indicator, Charging System Indicator Low Oil Pressure Indicator This indicator should never come on when the engine is running. If it starts flashing or stays on, the oil pressure has dropped very low or lost pressure. Serious engine damage is possible, and you should take immediate action. Running the engine with low oil pressure can cause serious mechanical damage almost immediately. Turn of f the engine as soon as you can saf ely get the vehicle stopped. 1. 2. 3. 4. 290 Safely pull off the road, and shut off the engine. Turn on the hazard warning indicators. Let the vehicle sit for a minute. Open the hood, and check the oil level (see page ). An engine very low on oil can lose pressure during cornering and other driving maneuvers. 184 If necessary, add oil to bring the level back to the full mark on the dipstick (see page 248 ). Start the engine, and watch the oil pressure indicator. If it does not go out within 10 seconds, turn off the engine. There is a mechanical problem that needs to be repaired before you can continue driving (see 298 Emergency Towing ). on page Charging System Indicator If the charging system indicator comes on brightly when the engine is running, the battery is not being charged. Immediately turn off all electrical accessories. Try not to use other electrically operated controls such as the power windows. Keep the engine running; starting the engine will discharge the battery rapidly. Go to a service station or garage where you can get technical assistance. 2008 Ridgeline ０７／０４／２７　１４：２０：１６　３１ＳＪＣ６２０　０２９６ If this indicator comes on while driving, it means one of the engine’s emissions control systems may have a problem. Even though you may feel no difference in your vehicle’s performance, it can reduce your fuel economy and cause increased emissions. Continued operation may cause serious damage. If you have recently refueled your vehicle, the indicator could come on because of a loose or missing fuel fill cap. You will also see a ‘‘TIGHTEN FUEL CAP’’ message on the information display. Tighten the cap until it clicks at least once. Tightening the cap will not turn the indicator off immediately; it can take several days of normal driving. If the indicator comes on repeatedly, even though it may turn off as you continue driving, have your vehicle checked by the dealer as soon as possible. If you keep driving with the malf unction indicator lamp on, you can damage your vehicle’s emissions controls and engine. Those repairs may not be covered by your vehicle’s warranties. The indicator may also come on with the ‘‘D’’ indicator. Readiness Codes Your vehicle has certain ‘‘readiness codes’’ that are part of the on-board diagnostics for the emissions systems. In some states, part of the emissions testing is to make sure these codes are set. If they are not set, the test cannot be completed. Malfunction Indicator Lamp If the battery in your vehicle has been disconnected or gone dead, these codes may be erased. It can take several days of driving under various conditions to set the codes again. To check if they are set, turn the ignition switch to the ON (II) position, without starting the engine. The malfunction indicator lamp will come on for 20 seconds. If it then goes off, the readiness codes are set. If it blinks five times, the readiness codes are not set. If possible, do not take your vehicle for a state emissions test until the readiness Emissions codes are set. Refer to Testing for more information (see 315 page ). 291 2008 Ridgeline ０７／０４／２７　１４：２０：２３　３１ＳＪＣ６２０　０２９７ Brake System Indicator However, if the brake pedal does not feel normal, you should take immediate action. A problem in one part of the system’s dual circuit design will still give you braking at two wheels. You will feel the brake pedal go down much farther before the vehicle begins to slow down, and you will have to press harder on the pedal. If the ABS indicator and the VSA system indicator come on with the brake system indicator, have your vehicle inspected by your dealer immediately. Slow down by shifting to a lower gear, and pull to the side of the road when it is safe. Because of the long distance needed to stop, it is hazardous to drive the vehicle. You should have it towed, and repaired as soon as possible (see Towing 298 Emergency ). on page If you must drive the vehicle a short distance in this condition, drive slowly and carefully. U.S. Canada The brake system indicator normally comes on when you turn the ignition switch to the ON (II) position, and as a reminder to check the parking brake. It will stay on if you do not fully release the parking brake. If the brake system indicator comes on while driving, the brake fluid level is probably low. Press lightly on the brake pedal to see if it feels normal. If it does, check the brake fluid level the next time you stop at a service station (see page 255 ). If the fluid level is low, take your vehicle to a dealer, and have the brake system inspected for leaks or worn brake pads. 292 2008 Ridgeline ０７／０４／２７　１４：２０：３１　３１ＳＪＣ６２０　０２９８ INTERIOR NOTCH UNDER-HOOD (PRIMARY) UNDER-HOOD (SECONDARY) Fuses The vehicle’s fuses are contained in three fuse boxes. The interior fuse box is on the driver’s lower left side. To remove the fuse box lid, put your finger in the notch on the lid, and pull it outward slightly, then pull it toward you and take it out of its hinges. The primary under-hood fuse box is on the passenger’s side. The secondary fuse box is next to the brake fluid reservoir. To open them, push the tabs as shown. 296 and Checking and Replacing Fuses If something electrical in your vehicle stops working, check for a blown fuse first. Determine from the chart on pages , or the diagram on the fuse box lid, which fuse or fuses control that device. Check those fuses first, but check all the fuses before deciding that a blown fuse is the cause. Replace any blown fuses, and check if the device works. 297 CONTINUED 293 2008 Ridgeline ０７／０４／２７　１４：２０：３８　３１ＳＪＣ６２０　０２９９ Fuses FUSE BLOWN BLOWN FUSE PULLER 1. Turn the ignition switch to the LOCK (0) position. Make sure the headlights and all other accessories are off. Remove the cover from the fuse box. 3. Check each of the large fuses in the primary under-hood fuse box by looking through the side window at the wire inside. Removing these fuses requires a Phillips-head screwdriver. 4. Check the smaller fuses in the under-hood fuse boxes and all the fuses in the interior fuse box by pulling out each one with the fuse puller provided in the primary under-hood fuse box. 294 2008 Ridgeline ０７／０４／２７　１４：２０：４５　３１ＳＪＣ６２０　０３００ BLOWN 5. Look for a blown wire inside the fuse. If it is blown, replace the fuse with one of the spare fuses of the same rating or lower. If you cannot drive the vehicle without fixing the problem, and you do not have a spare fuse, take a fuse of the same rating or a lower rating from one of the other circuits. Make sure you can do without that circuit temporarily (such as the accessory power socket or radio). If you replace the blown fuse with a spare fuse that has a lower rating, it might blow out again. This does not indicate anything wrong. Replace the fuse with one of the correct rating as soon as you can. Replacing a f use with one that has a higher rating greatly increases the chances of damaging the electrical system. If you do not have a replacement f use with the proper rating f or the circuit, install one with a lower rating. Fuses 6. If the replacement fuse of the same rating blows in a short time, there is probably a serious electrical problem in your vehicle. Leave the blown fuse in that circuit and have your vehicle checked by a qualified technician. If the driver’s power window fuse is removed, the AUTO function of the driver’s window may be disabled. To reset the AUTO function, see page 108 If the radio fuse is removed, 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 bars to enter the code (see page 166 ). 295 2008 Ridgeline ０７／０４／２７　１４：２０：５６　３１ＳＪＣ６２０　０３０１ Fuse Locations PRIMARY UNDER-HOOD FUSE BOX No. 10 11 12 Amps. 10 A − 10 A 15 A 10 A 10 A 7.5 A 15 A 15 A − 15 A 7.5 A Circuits Protected Left Headlight Low Beam Not Used Left Headlight High Beam Small Lights Right Headlight High Beam Right Headlight Low Beam Back Up FI ECU (PCM) DBW Not Used Heated Seat MG Clutch ＊ SECONDARY UNDER-HOOD FUSE BOX No. Amps.

Never tow your vehicle with just a rope or chain. It is very dangerous. The only way you can safely tow your vehicle is with flat-bed equipment. The operator will load your vehicle on the back of a truck. Any other method of towing will damage the drive system. When you contact the towing agency, inform them a flat-bed is required. Towing your vehicle with two tires on the ground will damage parts of the 4WD system. It should be transported on a f lat-bed truck or trailer. 298 If, due to damage, your vehicle must be towed with all four wheels on the ground, do the following: Release the parking brake. Start the engine. Shift to D for several seconds, then to N. Turn off the engine. Improper towing preparation will damage the transmission. Follow the above procedure exactly. If you cannot shif t the transmission or start the engine, your vehicle must be transported with the all f our wheels of f the ground. With all four wheels on the ground, it is best to tow the vehicle no farther than 50 miles (80 km), and keep the speed below 35 mph (55 km/h). The steering system can be damaged if the steering wheel is locked. Leave the ignition switch in the ACCESSORY (I) position, and make sure the steering wheel turns f reely bef ore you begin towing. Trying to lif t or tow your vehicle by the bumpers will cause serious damage. The bumpers are not designed to support the vehicle’s weight. 2008 Ridgeline ０７／０４／２７　１４：２１：１９　３１ＳＪＣ６２０　０３０４ If your vehicle gets stuck in sand, mud, or snow, call a towing service to pull it out (see the previous page). REAR TIE DOWN HOOK FRONT For very short distances, such as freeing the vehicle, you can use the tie down hooks on the lower left of the front and rear bumpers. If Your Vehicle Gets Stuck ‘‘Rocking’’ your vehicle between f orward and reverse gear or revving up the engine and allowing the wheels to spin f reely at high speeds can damage the automatic transmission. Use a tow service to prevent transmission damage. TIE DOWN HOOK CONTINUED 299 2008 Ridgeline ０７／０４／２７　１４：２１：２３　３１ＳＪＣ６２０　０３０５ If Your Vehicle Gets Stuck To avoid damage to your vehicle, use the tie down hooks f or straight, f lat ground towing only. Do not tow at an angle. These hooks should not be used f or open-road towing. 300 2008 Ridgeline ０７／０４／２７　１４：２１：２６　３１ＳＪＣ６２０　０３０６ Technical Information The diagrams in this section give you the dimensions and capacities of your vehicle and the locations of the identification numbers.

The vehicle identification number (VIN) is the 17-digit number your dealer uses to register your vehicle for warranty purposes. It is also necessary for licensing and insuring your vehicle. The easiest place to find the VIN is on a plate fastened to the top of the dashboard. You can see it by looking through the windshield on the driver’s side. It is also on the certification label attached to the driver’s doorjamb, and is stamped on the engine compartment bulkhead. The VIN is also provided in bar code on the certification label. 302 VEHICLE IDENTIFICATION NUMBER CERTIFICATION LABEL 2008 Ridgeline ０７／０４／２７　１４：２１：３５　３１ＳＪＣ６２０　０３０８ The engine number is stamped into the engine block.

For example, a tire graded 150 would wear one and one- half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual condi- tions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics. The tires on your vehicle meet all U.S. Federal Safety Requirements. All tires are also graded for treadwear, traction, and temperature performance according to Department of Transportation (DOT) standards. The following explains these gradings. Uniform Tire Quality Grading 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 All passenger car tires must conform to Federal Safety Requirements in addition to these grades. 306 2008 Ridgeline ０７／０４／２７　１４：２２：２９　３１ＳＪＣ６２０　０３１２ DOT Tire Quality Grading (U.S. Vehicles) Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. Temperature The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. 307 2008 Ridgeline ０７／０４／２７　１４：２２：３９　３１ＳＪＣ６２０　０３１３ Tire Labeling The tires that came on your vehicle have a number of markings.

P245/65R17 105T − Vehicle type (P indicates passenger vehicle). 245 − Tire width in millimeters. 65 − Aspect ratio (the tire’s section height as a percentage of its width). − Tire construction code (R indicates radial). 308 17 − Rim diameter in inches. 105 − Load index (a numerical code associated with the maximum load the tire can carry). − Speed symbol (an alphabetical code indicating the maximum speed rating). 2008 Ridgeline ０７／０４／２７　１４：２２：５０　３１ＳＪＣ６２０　０３１４ MaximumTirePressure Max Press − The maximum air pressure the tire can hold. MaximumTireLoad Max Load − The maximum load the tire can carry at maximum air pressure. TireIdentificationNumber(TIN) The tire identification number (TIN) is a group of numbers and letters that look like the following example. TIN is located on the sidewall of the tire. DOT B97R FW6X 2202 DOT − This indicates that the tire meets all requirements of the U.S. Department of Transportation. B97R − Manufacturer’s identification mark. FW6X − Tire type code. 2202 − Date of manufacture. Year Week Tire Labeling 309 2008 Ridgeline ０７／０４／２７　１４：２２：５６　３１ＳＪＣ６２０　０３１５ Tire Pressure Monitoring System (TPMS) − Required Federal Explanation Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale and when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under- inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. 310 2008 Ridgeline ０７／０４／２７　１４：２３：０１　３１ＳＪＣ６２０　０３１６ Tire Pressure Monitoring System (TPMS) − Required Federal Explanation Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is provided by a separate telltale, which displays the symbol ‘‘TPMS’’ when illuminated. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.
