- Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the fol- lowing situations, oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals.

l When the engine is new, for example directly after purchasing the vehi- cle or after replacing the engine
l If low quality oil or oil of an inappropriate viscosity is used
l When driving at high engine speeds or with a heavy load, when driving while accelerating or decelerating frequently
l When leaving the engine idling for a long time, or when driving fre- quently through heavy traffic


- Used engine oil
l Used engine oil contains potentially harmful contaminants which may cause skin disorders such as inflammation or 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.
l 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.
l Do not leave used engine oil within the reach of children.


- To prevent serious engine damage
Check the oil level on regular basis.

- When replacing the engine oil
l Be careful not to spill engine oil on the vehicle components.
l Avoid overfilling, as the engine could be damaged.
l Check the oil level on the dipstick every time you refill the vehicle.
l Be sure the engine oil filler cap is properly tightened.

Engine coolant

The coolant level is satisfactory if it is between the “F” and “L” lines on the reservoir when the engine is cold.

1 Reservoir cap

1 Reservoir cap
2 “F”
3 “L”

If the level is on or below the “L” line, add coolant up to the “F” line.

- If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, reservoir cap, radiator 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.

- Coolant selection
Only use “Toyota Super Long Life Coolant” or 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. (Enabled: -31°F [-35°C])
Canada:“Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Enabled: -44°F [-42°C])
For more details about engine coolant, contact your Lexus dealer.


- When the engine 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.


- When adding engine 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 damage to parts or paint.

Radiator and condenser

Check the radiator and condenser, and clear any foreign objects.

If any of the above parts are extremely dirty or you are not sure of their condition, have your vehicle checked by your Lexus dealer.


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

Brake fluid

Add brake fluid up toRemove the reservoir cap by hand. Add brake fluid up to the “MAX” line.

If you do not follow the procedure above, the reservoir may overflow.

- Brake fluid can absorb moisture from the air

Excess moisture in the fluid can cause a dangerous loss of braking effi- ciency. Use only newly opened brake fluid.


- When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage painted surfaces.

If fluid gets in your eyes, flush your eyes with clean water immediately.

If you still experience discomfort, see a doctor.


- If the fluid level is low
It is normal for the brake fluid level to go down slightly as the brake pads wear or when the fluid level in the accumulator is high.

If the reservoir needs frequent refilling, it may indicate a serious problem.

Power steering fluid

- Fluid level
The fluid level should be within the appropriate range.

1 Full (when cold)

Hot: Vehicle has been driven around 50 mph (80 km/h) for 20 minutes, or slightly longer in frigid temperatures. (Fluid temperature, 140°F - 175°F [60°C - 80°C]).

Cold:Engine has not been run for about five hours. (Room tem- perature, 50°F - 85°F [10°C - 30°C]).

Washer fluid

If any washer does not work or

If any washer does not work or the warning message appears on the multi-information dis- play, the washer tank may be empty. Add washer fluid.


- When refilling the washer fluid
Do not refill the washer fluid when the engine is hot or running, as the washer fluid contains alcohol and may catch fire if spilled on the engine etc.


- 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.
