Checking the engine oil Park the vehicle on level ground. After warming up the engine and turning off the engine, wait more than 5 minutes for the oil to drain back into the bottom of the engine. Holding a rag under the end, pull the dipstick out. Wipe the dipstick clean. Reinsert the dipstick fully with its protruding areas ( in the illustration) pointing towards engine. Holding a rag under the end, pull the dipstick out and check the oil level. Low Normal Excessive Wipe the dipstick and reinsert it fully. Checking the oil type and preparing the items needed Make sure to check the oil type and prepare the items needed before adding oil. Engine oil selection Lubrication system Oil quantity (Low Full) 1.6 qt. (1.5 L, 1.3 Imp.qt.) Items Clean funnel Adding engine oil If the oil level is below or near the low level mark, add engine oil of the same type as that already in the engine. 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. Note: 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, when towing, or when driving while accelerating or decelerating frequently When leaving the engine idling for a long time, or when driving frequently through heavy traffic After changing the engine oil The engine oil maintenance data should be reset. Perform the following procedures: Press or of the meter control switches and select . Press or of the meter control switches, select the “ Vehicle Settings” and then press . Press or of the meter control switches, select the “ Oil Maintenance” and then press . Select the “ Yes” and push .“ Reset Complete” is displayed on the multi-information display. 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. If oil is spilled on the engine cover To prevent the engine cover from being damaged, remove any engine oil from the engine cover as soon as possible using a neutral detergent. Do not use an organic solvent such as brake cleaner. Engine coolant Checking Engine coolant Coolant Checking Coolant Cooling system Intercooler coolant Checking Intercooler coolant Power control unit coolant Checking Power control unit coolantChecking the coolant The coolant level is satisfactory if it is between the “ F” and “ L” lines on the reservoir when the hybrid system is cold. Engine coolant Engine coolant reservoir cap “ F” line “ L” line If the level is on or below the “ L” line, add coolant up to the “ F” line. (If your vehicle overheats) Intercooler coolant Intercooler coolant reservoir cap “ F” line “ L” line If the level is on or below the “ L” line, add coolant up to the “ F” line. (If your vehicle overheats) Power control unit coolant Power control unit coolant reservoir cap “ FULL” line “ LOW” line If the level is on or below the “ LOW” line, add coolant up to the “ FULL” line. (If your vehicle overheats) Note: 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. U.S.A.:“ Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. (Minimum temperature: -31°F [-35°C]) Canada: “ Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized 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 cap, intercoolant reservoir 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 hybrid system is hot Do not remove the coolant reservoir 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. Radiator Condenser IntercoolerChecking the radiator, condenser and intercooler radiators Check the radiator, condenser and intercooler radiators and clear away any foreign objects. If either 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 hybrid system is hot Do not touch the radiator, condenser or intercooler radiators or condenser as they may be hot and cause serious injuries, such as burns. Brake Fluid Checking and adding the brake fluid Checking fluid level The brake fluid level should be between the “ MAX” and “ MIN” lines on the tank. Brake fluid reservoir cap “ MAX” line “ MIN” line Adding fluid Make sure to check the fluid type and prepare the necessary item. Fluid type FMVSS No.116 DOT 3 or SAE J1703 brake fluid FMVSS No.116 DOT 4 or SAE J1704 brake fluid Item Clean funnel Note: Brake fluid can absorb moisture from the air Excess moisture in the brake fluid can cause a dangerous loss of braking efficiency. Use only newly opened brake fluid. 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, see 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. Washer Adding Fluid Washer Adding the washer fluid If any washer does not work the washer tank may be empty. Add washer fluid. Warning: When adding washer fluid Do not add washer fluid when the hybrid system is hot or operating as washer fluid contains alcohol and may catch fire if spilled on the hybrid system, etc. Notice: Do not use any fluid other than washer fluid Do not use soapy water or antifreeze instead of washer fluid.Doing so may cause streaking on the vehicle’s painted surfaces, as well as damaging the pump leading to problems of the washer fluid not spraying. Diluting washer fluid Dilute washer fluid with water as necessary.Refer to the freezing temperatures listed on the label of the washer fluid bottle.
