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 consumptionA 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 engineIf low quality oil or oil of an inappropriate viscosity is usedWhen driving at high engine speeds or with a heavy load, when towing, or when driving while accelerating or decelerating frequentlyWhen leaving the engine idling for a long time, or when driving frequently through heavy trafficAfter changing the engine oilThe engine oil maintenance data should be reset. Perform the following procedures:Press or of the meter control switch to select on the multi-information display.Press or of the meter control switch, select the “ Vehicle Settings” then “ Oil Maintenance”. (To confirm setting, press .)Select the “ Yes” and press .A message is displayed on the multi-information display.WARNING:Used engine oilUsed 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 Lexus 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 damageCheck the oil level on a regular basis.When replacing the engine oilBe 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.CHECKING THE COOLANTThe 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” lineIf the level is on or below the “ LOW” line, add coolant up to the “ FULL” line. (If your vehicle overheats)Note:Coolant selectionOnly 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 Lexus dealer.If the coolant level drops within a short time of replenishingVisually check the radiator, hoses, engine coolant reservoir cap, drain cock and water pump.If you cannot find a leak, have your Lexus dealer test the cap and check for leaks in the cooling system.WARNING:When the engine is hotDo not remove the engine coolant reservoir cap and 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 coolantCoolant 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 coolantBe sure to wash it off with water to prevent it from damaging parts or paint.CHECKING THE RADIATOR AND CONDENSERCheck the radiator and condenser 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 Lexus dealer.WARNING:When the engine is hotDo not touch the radiator or condenser as they may be hot and cause serious injuries, such as burns.CHECKING AND ADDING THE BRAKE FLUIDChecking fluid levelThe brake fluid level should be between the “ MAX” and “ MIN” lines on the tank.
Adding fluidMake sure to check the fluid type and prepare the necessary item.Fluid typeFMVSS No.116 DOT 3 or SAE J1703 brake fluidItemClean funnelNote:Brake fluid can absorb moisture from the airExcess moisture in the brake fluid can cause a dangerous loss of braking efficiency. Use only newly opened brake fluid.WARNING:When filling the reservoirTake 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 highIt 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.BATTERYCheck the battery as follows.Battery exteriorMake sure that the battery terminals are not corroded and that there are no loose connections, cracks, or loose clamps.
