Engine oil

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

Checking the engine oil

1. Park the vehicle on level ground. After turning off the hybrid system, wait more than five minutes for the oil to drain back into the bottom of the engine.

2. Hold a rag under the end and pull the dipstick out.

3. Wipe the dipstick clean.

4. Reinsert the dipstick fully.

5. Holding a rag under the end, pull the dipstick out and check the oil level.

6. Wipe the dipstick and reinsert it fully.

1. Low.

2. Full.

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.

Make sure to check the oil type and prepare the items needed before adding oil.

1. Remove the oil filler cap by turning it counterclockwise.

2. Add engine oil slowly, checking the dipstick.

3. Install the oil filler cap by turning it clockwise.

Engine oil consumption

The amount of engine oil consumed depends on the oil viscosity, the quality of
the oil and the way the vehicle is driven.

More oil is consumed under driving conditions such as high speeds and frequent acceleration and deceleration.

A new engine consumes more oil.

When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately.

Oil consumption: Max. 1.1 qt./600 miles, 0.9 Imp. qt./600 miles (1.0 L per 1000
km)
If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600 miles
(1000 km), contact your Lexus dealer.

After changing the engine oil (USA only)

The engine oil maintenance data should be reset. Perform the following procedure:
1. Display the trip meter “A” , then turn the “POWER” switch off.

2. While pressing the “ODO/TRIP” button, turn the “POWER” switch to ON mode.

3. Keep the “ODO/TRIP” button pressed for about 5 seconds. The resetting procedure is complete when “000000” in the trip meter flashes once and the message in the multiinformation display disappears.

CAUTION:
Used engine oil
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.

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 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.

Coolant

The coolant level is satisfactory if it is between the “FULL” and “LOW” lines on the reservoir when the engine and hybrid system are cold.

- Engine coolant reservoir

1. Reservoir cap.

2. “FULL” line.

3. “LOW” line.

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

- Power control unit coolant reservoir

1. Reservoir cap.

2. “FULL” line.

3. “LOW” line.

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

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. (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 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 Lexus dealer test the cap and check for leaks in
the cooling systems.

CAUTION:
When the engine and hybrid system are 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 burns or other injuries.

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 damaging to parts or paint.

Radiator and condenser

Check the radiator and condenser and clear any foreign objects.

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

CAUTION:
The radiators and condenser may be hot after driving Do not touch the radiator or condenser as they may be hot and burn you.

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.

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.

CAUTION:
When filling the reservoir Take care because brake fluid can harm your hands or 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, may be a serious problem.

Washer fluid

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

CAUTION:
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 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 washer fluid tank.
