■Adding engine oil
If the oil level is below or near the
low level mark, add engine oil of
the same type as already in the
engine.
Make sure to check the oil type and prepare the items needed before
adding oil.
Remove the oil filler cap.
Add engine oil slowly, checking the dipstick.
Install the filler cap, turning it clockwise.
It takes about 1.6 qt. (1.5 L, 1.3 lmp. qt.) to raise the oil level from low to full on the
dipstick.

■Recommended viscosity
SAE 5W-30 is the best choice for
good fuel economy, and good
starting in cold weather.
If SAE 5W-30 oil is not available,
SAE 10W-30 oil may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.
■How to read oil container labels
Some oil containers are labeled with ILSAC certification marks that
help you to select the proper oil.

■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 fre-
quent 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 lmp.qt./600 miles (1.0 L per 1000
km)
●If you consume more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles (1000 km),
contact your Lexus dealer.
■Changing the engine oil (USA only)
To reset the oil change system, follow the procedure below:
1. Turn the “ENGINE START STOP” switch OFF with the trip meter A reading
shown. (→P. 1 2 5 )
2. While pressing the trip meter reset button, set the “ENGINE START STOP”
switch to the IGNITION ON mode. Continue to press and hold the button until
the trip meter displays 000000.
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 dis-
pose 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 con-
cerning recycling or disposal.
●Do not leave used engine oil within the reach of children.

Maintenance and care
Engine coolant
The coolant level is satisfactory if it is between the F and L lines on the res-
ervoir when the engine is cold.
Full
Low
If the level is on or below the L line,
add coolant up to the F line.
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.
■When adding the engine coolant
When installing the reservoir cap, make sure
that the engine coolant reservoir hose posi-
tioned as shown in the illustration.

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 [-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.
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 burns or other injuries.
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.

Maintenance and care
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.
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
CAUTION
■When the engine is hot
Do not touch the radiator or condenser, as they may be hot and you may be burned.
Fluid typeFMVSS No.116 DOT 3 or SAE J1703 brake fluid
ItemsClean 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.

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

Add fluid (when hot)
Hot: Vehicle has been driven around 50 mph (80 km/h) for 20 min-
utes, or slightly longer in frigid temperatures. (Fluid tempera-
ture, 140°F - 175°F [60°C - 80°C])
Cold: Engine has not been run for about 5 hours. (Room tempera-
ture, 50°F - 85°F [10°C - 30°C])
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.

Reinstall the reservoir cap.
Remove the reservoir cap again and look at the fluid level.

Check the steering box case, vane pump and hose connections for leaks or dam-
age.
