Maintenance 205 Emission inspection and maintenance (I/M) programs Some states have vehicle emission inspection programs which include OBD (On Board Diagnostics) checks. The OBD system monitors the operation of the emission control system. If the malfunction indicator lamp comes on The OBD system determines that a problem exists somewhere in the emission control system. Your vehicle may not pass the I/M test and may need to be repaired. Contact your Toyota dealer to service the vehicle. Your vehicle may not pass the I/M test in the following situations: ● When the battery is disconnected or discharged Readiness codes that are set during ordinary driving are erased. Also, depending on your driving habits, the readiness codes may not be completely set. ● When the fuel tank cap is loose The malfunction indicator lamp comes on indicating a temporary malfunction and your vehicle may not pass the I/M test. When the malfunction indicator lamp still remains on after sev- eral driving trips The error code in the OBD system will not be cleared unless the vehi- cle is driven 40 or more times. If your vehicle does not pass the I/M test Contact your Toyota dealer to prepare the vehicle for re-testing. 206 6-3.

Remove the oil filler cap by turning it counterclockwise. Add engine oil slowly, checking the dipstick. Install the oil filler cap by turning it clockwise. ■Engine oil consumption A certain amount of engine oil will be consumed while driving. In the following situations, oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals. ●When the engine is new, for example directly after purchasing the vehicle or after replacing the engine ●If low quality oil or oil of an inappropriate viscosity is used ●When driving at high engine speeds or with a heavy load, or when driving while accelerating or decelerating frequently ●When leaving the engine idling for a long time, or when driving frequently through heavy traffic 216 6-3. Do-it-yourself maintenance WARNING ■Used engine oil ●Used engine oil contains potentially harmful contaminants which may cause skin disorders such as inflammation and skin cancer, so care should be taken to avoid prolonged and repeated contact. To remove used engine oil from your skin, wash thoroughly with soap and water. ●Dispose of used oil and filters only in a safe and acceptable manner. Do not dispose of used oil and filters in household trash, in sewers or onto the ground. Call your Toyota dealer, service station or auto parts store for information concerning recycling or disposal. ●Do not leave used engine oil within the reach of children. NOTICE ■To prevent serious engine damage Check the oil level on a regular basis. ■When replacing the engine oil ●Be careful not to spill engine oil on the vehicle components. ●Avoid overfilling, or the engine could be damaged. ●Check the oil level on the dipstick every time you refill the vehicle. ●Be sure the engine oil filler cap is properly tightened. Engine coolant The coolant level is satisfactory if it is between the “FULL” and “LOW” lines on the reservoir when the engine is cold. Reservoir cap “FULL” line “LOW” line If the level is on or below the “LOW” line, add coolant up to the “FULL” line. (P. 300) 6-3. Do-it-yourself maintenance 217 ■Coolant selection Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology.  Except Canada “Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion- ized water. (Minimum temperature: -31F [-35C])  Canada “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deion- ized water. (Minimum temperature: -44F [-42C]) For more details about coolant, contact your Toyota dealer. ■If the coolant level drops within a short time of replenishing Visually check the radiator, hoses, engine coolant reservoir caps, radiator cap, drain cock and water pump. If you cannot find a leak, have your Toyota dealer test the cap and check for leaks in the cooling system. WARNING ■When the engine is hot Do not remove the radiator cap. The cooling system may be under pressure and may spray hot coolant if the cap is removed, causing serious injuries, such as burns. NOTICE ■When adding coolant Coolant is neither plain water nor straight antifreeze. The correct mixture of water and antifreeze must be used to provide proper lubrication, corrosion protection and cooling. Be sure to read the antifreeze or coolant label. ■If you spill coolant Be sure to wash it off with water to prevent it from damaging parts or paint. 218 6-3. Do-it-yourself maintenance Radiator and condenser Check the radiator and condenser and clear away any foreign objects. If any of the above parts is extremely dirty or you are not sure of their condition, have your vehicle inspected by your Toyota dealer. WARNING ■When the engine is hot Do not touch the radiator or condenser as they may be hot and cause seri- ous injuries, such as burns. Brake fluid ■ Checking fluid level The brake fluid level should be between the “MAX” and “MIN” lines on the tank. ■ Adding fluid Make sure to check the fluid type and prepare the necessary item. Fluid type Item FMVSS No.116 DOT 3 or SAE J1703 brake fluid Clean funnel ■Brake fluid can absorb moisture from the air Excess moisture in the brake fluid can cause a dangerous loss of braking effi- ciency. Use only newly opened brake fluid. 6-3. Do-it-yourself maintenance 219 WARNING ■When filling the reservoir Take care as brake fluid can harm your hands and eyes and damage painted surfaces. If fluid gets on your hands or in your eyes, flush the affected area with clean water immediately. If you still experience discomfort, consult a doctor. NOTICE ■If the fluid level is low or high It is normal for the brake fluid level to go down slightly as the brake pads wear out or when the fluid level in the accumulator is high. If the reservoir needs frequent refilling, there may be a serious problem. Battery Check the battery as follows. ■ Battery exterior Make sure that the battery terminals are not corroded and that there are no loose connections, cracks, or loose clamps. Terminals Hold-down clamp 220 6-3. Do-it-yourself maintenance ■Before recharging When recharging, the battery produces hydrogen gas which is flammable and explosive. Therefore, observe the following before recharging: ●If recharging with the battery installed on the vehicle, be sure to disconnect the ground cable. ●Make sure the power switch on the charger is off when connecting and dis- connecting the charger cables to the battery. WARNING ■Chemicals in the battery Batteries contain poisonous and corrosive sulfuric acid and may produce hydrogen gas which is flammable and explosive. To reduce the risk of death or serious injury, take the following precautions while working on or near the battery: ●Do not cause sparks by touching the battery terminals with tools. ●Do not smoke or light a match near the battery. ●Avoid contact with eyes, skin and clothes. ●Never inhale or swallow electrolyte. ●Wear protective safety glasses when working near the battery. ●Keep children away from the battery. ■Where to safely charge the battery Always charge the battery in an open area.

If possible, continue to apply water with a sponge or cloth while traveling to the nearest medical facility. ●If electrolyte gets on your skin Wash the affected area thoroughly. If you feel pain or burning, get medical attention immediately. ●If electrolyte gets on your clothes It can soak through clothing on to your skin. Immediately take off the cloth- ing and follow the procedure above if necessary. ●If you accidentally swallow electrolyte Drink a large quantity of water or milk. Get emergency medical attention immediately. NOTICE ■When recharging the battery Never recharge the battery while the engine is running. Also, be sure all accessories are turned off. Washer fluid If washer does not spray or the low washer fluid warning light comes on the washer tank may be empty. Add washer fluid. (if equipped), 222 6-3. Do-it-yourself maintenance WARNING ■When adding washer fluid Do not add washer fluid when the engine is hot or running as washer fluid contains alcohol and may catch fire if spilled on the engine, etc. NOTICE ■Do not use any fluid other than washer fluid Do not use soapy water or engine antifreeze instead of washer fluid. Doing so may cause streaking on the vehicle’s painted surfaces. ■Diluting washer fluid Dilute washer fluid with water as necessary. Refer to the freezing temperatures listed on the label of the washer fluid bot- tle. 6-3. Do-it-yourself maintenance 223 Tires Replace or rotate tires in accordance with maintenance sched- ules and treadwear. Checking tires New tread Treadwear indicator Worn tread The location of treadwear indica- tors is shown by the “TWI” or “” marks, etc., molded on the side- wall of each tire. Check spare tire condition and pressure if not rotated. Tire rotation Rotate the shown. tires in the order To equalize tire wear and extend tire life, Toyota recommends that tire rotation is carried out at the same interval as tire inspection. Vehicles with P195/50R16 tires: Do not fail to initialize the tire pressure warning system after tire rotation. Front 224 6-3. Do-it-yourself maintenance Tire pressure warning system (if equipped) Your vehicle is equipped with a tire pressure warning system that uses tire pressure warning valves and transmitters to detect low tire infla- tion pressure before serious problems arise. (P. 274) The compact spare tire is not equipped with a tire pressure warning valve and transmitter. Installing tire pressure warning valves and transmitters (vehicles with a tire pressure warning system) When replacing tires or wheels, tire pressure warning valves and transmitters must also be installed. When new tire pressure warning valves and transmitters are installed, new ID codes must be registered in the tire pressure warning computer and the tire pressure warning system must be initialized. Have tire pressure warning valve and transmitter ID codes registered by your Toyota dealer. (P. 225) ■ The tire pressure warning system must be initialized in the fol- lowing circumstances: ● For vehicles with P195/50R16 tires, when rotating front and rear tires which have different tire inflation pressures ● When the tire inflation pressure is changed such as when chang- ing traveling speed When the tire pressure warning system is initialized, the current tire inflation pressure is set as the benchmark pressure. 6-3. Do-it-yourself maintenance 225 ■ How to initialize the tire pressure warning system Park the vehicle in a safe place and turn the engine switch to the “LOCK” position. Initialization cannot be performed while the vehicle is moving. Adjust the tire pressure to the specified cold tire inflation pres- sure level. (P. 315) Make sure to adjust the tire pressure to the specified cold tire infla- tion pressure level. The tire pressure warning system will operate based on this pressure level. Turn the engine switch to the “ON” position. Press and hold the tire pres- sure warning reset switch until the tire pressure warn- ing light blinks slowly 3 times. Wait for a few minutes with the engine switch in the “ON” position and then turn the engine switch to the “LOCK” position. Registering ID codes (vehicles with a tire pressure warning sys- tem) The tire pressure warning valve and transmitter is equipped with a unique ID code. When replacing a tire pressure warning valve and transmitter, it is necessary to register the ID code. Have the ID code registered by your Toyota dealer. 226 6-3. Do-it-yourself maintenance ■When to replace your vehicle’s tires Tires should be replaced if: ●You have tire damage such as cuts, splits, cracks deep enough to expose the fabric, and bulges indicating internal damage ●A tire goes flat repeatedly or cannot be properly repaired due to the size or location of a cut or other damage If you are not sure, consult with your Toyota dealer. ■Replacing tires and wheels (vehicles with a tire pressure warning system) If the ID code of the tire pressure warning valve and transmitter is not reg- istered, the tire pressure warning system will not work properly. After driv- ing for about 20 minutes, the tire pressure warning light blinks for 1 minute and stays on to indicate a system malfunction. ■Tire life Any tire over 6 years old must be checked by a qualified technician even if it has seldom or never been used or damage is not obvious. ■Routine tire inflation pressure checks (vehicles with a tire pressure warning system) The tire pressure warning system does not replace routine tire inflation pressure checks. Make sure to check tire inflation pressure as part of your routine of daily vehicle checks. ■Low profile tires (vehicles with 195/50R16 tires) Generally, low profile tires will wear more rapidly and tire grip perfor- mance will be reduced on snowy and/or icy roads when compared to standard tires. Be sure to use snow tires or tire chains on snowy and/or icy roads and drive carefully at a speed appropriate for road and weather conditions. 6-3. Do-it-yourself maintenance 227 ■Maximum load of tire Check that the maximum load of the replacement tire is greater than 1/2 of the Gross Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever is greater. For the GAWR, see the Certification Label. For the maximum load of the tire, see the load limit at maximum cold tire inflation pressure mentioned on the sidewall of the tire. (P. 320) ■Tire types ●Summer tires Summer tires are high-speed performance tires best suited to highway driving under dry conditions. Since summer tires do not have the same traction performance as snow tires, summer tires are inadequate for driving on snow-covered or icy roads. For driving on snow-covered roads or icy roads, the use of snow tires is recommended. When install- ing snow tires, be sure to replace all four tires. ●All season tires All season tires are designed to provide better traction in snow and to be adequate for driving in most winter conditions as well as for use year-round. All season tires, however, do not have adequate traction performance compared with snow tires in heavy or loose snow. Also, all season tires fall short in acceleration and handling performance com- pared with summer tires in highway driving. ●Snow tires For driving on snow-covered roads or icy roads, we recommend using snow tires. If you need snow tires, select tires of the same size, con- struction and load capacity as the originally installed tires. Since your vehicle has radial tires as original equipment, make sure your snow tires also have radial construction. Do not install studded tires without first checking local regulations for possible restrictions. Snow tires should be installed on all wheels. (P. 167) 6-3. Do-it-yourself maintenance 228 ■Initializing the tire pressure warning system (vehicles with a tire pressure warning system) Initialize the system with the tire inflation pressure adjusted to the speci- fied level. ■If the tread on snow tires wears down below 0.16 in. (4 mm) The effectiveness of the tires as snow tires is lost. ■If you press the tire pressure warning reset switch accidentally (vehi- cles with a tire pressure warning system) If initialization is performed, adjust the tire inflation pressure to the speci- fied level and initialize the tire pressure warning system again. ■When the initialization of the tire pressure warning system has failed (vehicles with a tire pressure warning system) Initialization can be completed in a few minutes. However, in the following cases, the settings has not been recorded and the system will not operate properly. If repeated attempts to record tire inflation pressure settings are unsuccessful, have the vehicle inspected by your Toyota dealer. ●When operating the tire pressure warning reset switch, the tire pressure warning light does not blink 3 times. ●After driving for a certain period of time since the initialization has been completed, the warning light comes on after blinks for 1 minute. ■Certification for the tire pressure warning system  For vehicles sold in U.S.A. FCC ID: PAXPMVC010 FCC ID: HYQ23AAD NOTE: This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC WARNING: Changes or modifications not expressly approved by the party responsi- ble for compliance could void the user’s authority to operate the equip- ment. 6-3. Do-it-yourself maintenance 229 WARNING ■When inspecting or replacing tires Observe the following precautions to prevent accidents. Failure to do so may cause damage to parts of the drive train as well as dangerous handling characteristics, which may lead to an accident resulting in death or serious injury. ●Do not mix tires of different makes, models or tread patterns. Also, do not mix tires of remarkably different treadwear. ●Do not use tire sizes other than those recommended by Toyota. ●Do not mix differently constructed tires (radial, bias-belted or bias-ply tires). ●Do not mix summer, all season and snow tires. ●Do not use tires that have been used on another vehicle. Do not use tires if you do not know how they were used previously. ●Do not tow if your vehicle has a compact spare tire installed. ■When initializing the tire pressure warning system (vehicles with a tire pressure warning system) Do not operate the tire pressure warning reset switch without first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pressure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal. 230 6-3. Do-it-yourself maintenance NOTICE ■Repairing or replacing tires, wheels, tire pressure warning valves, transmitters and tire valve caps (vehicles with a tire pressure warn- ing system) ●When removing or fitting the wheels, tires or the tire pressure warning valves and transmitters, contact your Toyota dealer as the tire pres- sure warning valves and transmitters may be damaged if not handled correctly. ●When replacing tire valve caps, do not use tire valve caps other than those specified. The cap may become stuck. ■To avoid damage to the tire pressure warning valves and transmit- ters (vehicles with a tire pressure warning system) When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used, contact your Toyota dealer or other qualified service shop as soon as possible. Make sure to replace the tire pressure warning valve and transmitter when replacing the tire. (P. 224) ■Driving on rough roads Take particular care when driving on roads with loose surfaces or pot- holes. These conditions may cause losses in tire inflation pressure, reducing the cushioning ability of the tires. In addition, driving on rough roads may cause damage to the tires themselves, as well as the vehicle’s wheels and body. ■Low profile tires (vehicles with 195/50R16 tires) Low profile tires may cause greater damage than usual to the tire wheel when sustaining impact from the road surface. Therefore, pay attention to the following: ●Be sure to use proper tire inflation pressure. If tires are under-inflated, they may be damaged more severely. ●Avoid potholes, uneven pavement, curbs and other road hazards. Fail- ure to do so may lead to severe tire and wheel damage. ■If tire inflation pressure of each tire becomes low while driving Do not continue driving, or your tires and/or wheels may be ruined. 6-3. Do-it-yourself maintenance 231 Tire inflation pressure The recommended cold tire infla- tion pressure and tire size are dis- played on the tire and loading information label. (P. 315) 232 6-3. Do-it-yourself maintenance Inspection and adjustment procedure Tire valve Tire pressure gauge Remove the tire valve cap. Press the tip of the tire pressure gauge onto the tire valve. Read the pressure using the gauge gradations. If the tire inflation pressure is not at the recommended level, adjust the pressure. If you add too much air, press the center of the valve to deflate. After completing the tire inflation pressure measurement and adjustment, apply soapy water to the valve and check for leakage. Put the tire valve cap back on. 6-3. Do-it-yourself maintenance 233 ■Tire inflation pressure check interval You should check tire inflation pressure every two weeks, or at least once a month. Do not forget to check the spare. ■Effects of incorrect tire inflation pressure Driving with incorrect tire inflation pressure may result in the following: ●Reduced fuel efficiency ●Reduced driving comfort and tire life ●Reduced safety ●Damage to the drive train If a tire needs frequent inflating, have it checked by your Toyota dealer. ■Instructions for checking tire inflation pressure When checking tire inflation pressure, observe the following: ●Check only when the tires are cold. If your vehicle has been parked for at least 3 hours or has not been driven for more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure reading. ●Always use a tire pressure gauge. The appearance of the tire can be misleading. In addition, tire inflation pressure that is even just a few pounds off can affect ride quality and handling. ●Do not reduce tire inflation pressure after driving. It is normal for tire inflation pressure to be higher after driving. ●Never exceed the vehicle capacity weight. Passengers and luggage weight should be placed so that the vehicle is balanced. 234 6-3. Do-it-yourself maintenance WARNING ■Proper inflation is critical to save tire performance Keep your tires properly inflated. Otherwise, the following conditions may occur and result in an accident causing death or serious injury: ●Excessive wear ●Uneven wear ●Poor handling ●Possibility of blowouts resulting from overheated tires ●Poor sealing of the tire bead ●Wheel deformation and/or tire separation ●A greater possibility of tire damage from road hazards NOTICE ■When inspecting and adjusting tire inflation pressure Be sure to put the tire valve caps back on. Without the valve caps, dirt or moisture could get into the valve and cause air leakage, which could result in an accident. If the caps are lost, replace them as soon as possible. 6-3. Do-it-yourself maintenance 235 Wheels If a wheel is bent, cracked or heavily corroded, it should be replaced. Otherwise, the tire may separate from the wheel or cause a loss of handling control. Wheel selection When replacing wheels, care should be taken to ensure that they are equivalent to those removed in load capacity, diameter, rim width and inset*. Replacement wheels are available at your Toyota dealer. *: Conventionally referred to as “offset”. Toyota does not recommend using the following: ● Wheels of different sizes or types ● Used wheels ● Bent wheels that have been straightened Aluminum wheel precautions (if equipped) ● Use only Toyota wheel nuts and wrenches designed for use with your aluminum wheels. ● When rotating, repairing or changing your tires, check that the wheel nuts are still tight after driving 1000 miles (1600 km). ● Be careful not to damage the aluminum wheels when using tire chains. ● Use only Toyota genuine balance weights or equivalent and a plas- tic or rubber hammer when balancing your wheels. 236 6-3. Do-it-yourself maintenance ■When replacing wheels (vehicles with a tire pressure warning sys- tem) The wheels of your vehicle, except for the compact spare tire, are equipped with tire pressure warning valves and transmitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire inflation pressure. Whenever wheels are replaced, tire pres- sure warning valves and transmitters must be installed. (P. 224) WARNING ■When replacing wheels ●Do not use wheels that are a different size from those recommended in the Owner’s Manual, as this may result in a loss of handling control. ●Never use an inner tube in a leaking wheel which is designed for a tubeless tire. Doing so may result in an accident, causing death or seri- ous injury. ■When installing the wheel nuts facing tapered ends ●Be sure to install the wheel nuts with the inward. Installing the nuts with the tapered ends facing outward can cause the wheel to break and eventually cause the wheel to come off while driving, which could to an accident resulting in death or serious injury. lead Tapered portion ●Never use oil or grease on the wheel bolts or wheel nuts. Oil and grease may cause the wheel nuts to be excessively tightened, leading to bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts to loosen and the wheel may fall off, causing an accident and resulting in death or serious injury. Remove any oil or grease from the wheel bolts or wheel nuts. ■Use of defective wheels prohibited Do not use cracked or deformed wheels. Doing so could cause the tire to leak air during driving, possibly causing an accident. 6-3. Do-it-yourself maintenance 237 NOTICE ■Replacing tire pressure warning valves and transmitters (vehicles with a tire pressure warning system) ●Because tire repair or replacement may affect the tire pressure warn- ing valves and transmitters, make sure to have tires serviced by your Toyota dealer or other qualified service shop. In addition, make sure to purchase your tire pressure warning valves and transmitters at your Toyota dealer. ●Ensure that only genuine Toyota wheels are used on your vehicle. Tire pressure warning valves and transmitters may not work properly with non-genuine wheels. 238 6-3.
