CAUTION
■ When raising your vehicle:
Make sure to observe the following to reduce the possibility of death or serious injury.
● Lift up the vehicle using a floor jack such as the one shown in the illustration.
● When using a floor jack, follow the instructions of the manual provided with the jack.
● Do not use the jack that was supplied with your vehicle.
● Do not put any part of your body or get underneath the vehicle supported only by the floor jack.
● Always use floor jack and/or automotive jack stands on a solid, flat, level surface.
● Do not start the engine while the vehicle is supported by the floor jack.
● Stop the vehicle on level firm ground, firmly set the parking brake and put the shift lever in P.
● Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage the vehicle and may cause the vehicle to fall off the floor jack.
● Do not raise the vehicle while someone is in the vehicle.
● When raising the vehicle, do not place any objects on top of or underneath the floor jack.

Engine oil
With the engine at operating temperature and turned off, check the oil level on the dipstick.
■ Checking the engine oil
STEP 1
Park the vehicle on level ground. After warming up the engine and turning it off, wait more than 5 minutes for the oil to drain back into the bottom of the engine.
STEP 2
Hold a rag under the end and pull the dipstick out.

■ 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 you consume more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600 miles (1000 km), contact your Lexus dealer.
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 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 retightened.
Engine coolant
The coolant level is satisfactory if it is between the F and L lines on the reservoir when the engine is cold.
Full
Low
If the level is on or below the L line, add coolant up to the F line.
■ When adding the engine coolant
When installing the reservoir cap, make sure that the engine coolant reservoir hose positioned as shown in the illustration.
382
4-3. Do-it-yourself maintenance
■ If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, engine coolant filler cap, radiator cap, drain cock and water pump.
If you cannot find a leak, have your Lexus dealer pressure 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.
USA: “Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. (Enabled: -31 F [-35C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Enabled: -44 F [-42C])
For more details about engine coolant, contact your Lexus dealer.
CAUTION
■ When the engine is hot
Do not remove 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 engine coolant
Coolant is neither plain water not straight antifreeze. The correct mixture of water and anti freeze 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 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
■ 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
■ Checking fluid level
The brake fluid level should be between the “MAX” and “MIN” lines on the tank.
Make sure to check the fluid type and prepare the necessary items.
■ Adding fluid
Fluid type
Items
FMVSS No.116 DOT 3 or SAE J1703 brake fluid
Clean funnel
■ Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dangerous loss of braking efficiency. Use only newly opened brake fluid.

4-3. Do-it-yourself maintenance
CAUTION
■ 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.
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 or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.
