Engine oil Checking Checking the engine oil

With the engine at operating temperature and turned off, check the oil level on the dipstick.

Park the vehicle on level ground. After warming up the engine and turning off the hybrid system, wait about 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.

Holding a rag under the end, pull the dipstick out and check whether the oil level is above low level mark.

Low level mark

The shape of the dipstick may differ depending on the type of vehicle or engine.

Wipe the dipstick and reinsert it fully.

Notice:

To prevent serious engine damage

Check the oil level on a regular basis.

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, or when driving while accelerating or decelerating frequently

When leaving the engine idling for a long time, or when driving frequently through heavy traffic

Engine oil level rise

If the vehicle is repeatedly driven without the engine warmed up, moisture caused by dew condensation inside the engine or fuel which did not burn mixes into the engine oil, resulting in a rise in engine oil level.

For example, the engine become difficult to be warmed up in the following situations.

When driving a short distance

When driving at a low speed

When the outside temperature is low

When checking the engine oil, make sure that the engine is warmed up. If the engine oil level exceeds the refill upper limit mark, contact your Toyota dealer.

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:

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

Cooling system

Coolant Checking Checking the coolant

The coolant level is satisfactory if it is between the “ MAX” and “ MIN” lines on the reservoir when the hybrid system is cold.

Engine coolant reservoir

Reservoir cap

“ MAX” line

“ MIN” line

If the level is on or below the “ MIN” line, add coolant up to the “ MAX” line. (If the high coolant temperature warning light comes on or flashes or “Engine Coolant Temp High Stop in a Safe Place See Owner’s Manual” is shown on the multi-information display)

Power control unit coolant reservoir

Reservoir cap

“ F” line

“ L” line

If the level is on or below the “ L” line, add coolant up to the “ F” line. (If “Hybrid System Overheated Output Power Reduced” is shown on the multi-information display)

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 radiators, hoses, engine/power control unit coolant reservoir caps, 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 engine/power control unit coolant reservoir caps or 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.

Radiator

CondenserChecking the radiator and condenser

Check 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 Toyota dealer.

Warning:

When the hybrid system is hot

Do not touch the radiator or condenser as they may be hot and cause serious injuries, such as burns.

When the electric cooling fan is operating

Do not touch the engine compartment.

With the power switch in ON, the electric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is high. Be sure the power switch is OFF when working near the electric cooling fan or radiator grille.
