Maintenance and care WARNING
The engine compartment contains many mechan isms and fluids that may move suddenly,
become hot, or become electrically energize d. To avoid death or serious injury, observe
the following precautions: ■
When working on the engine compartment ●
Keep hands, clothing and tools away from the moving fan and engine drive belt.●
Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driving
as they may be hot. Oil and other fluids may also be hot. ●
Do not leave anything that may burn easily, such as paper or rags, in the engine com-
partment. ●
Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel and
battery fumes are flammable. ●
Be extremely cautious when working on the battery. It contains poisonous and corro-
sive sulfuric acid. ■
When working near the electric cooling fans or radiator grille
Be sure the engine switch is off. With the engine switch in IGNITION ON mode, the
electric cooling fans may auto matically start to run if the air conditioning is on and/or
the coolant temperature is high. (  P. 481) ■
When working on or under the vehicle
Do not get under the vehicle with just the jack supporting it.
Always use automotive jack stands or other solid supports. ■
Safety glasses
Wear safety glasses to prevent flying or falling material, flui d spray, etc. from getting in
your eyes.
NOTICE ■
If you remove the air cleaner filter
Driving with the air cleaner f ilter removed may cause excessive engine wear due to dirt
in the air.

it off, wait more than 5 minutes for the oil to drain back into the bottom of
the engine.
Holding a rag under the end, pull

oil.
Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.■
Engine oil consumption
A certain amount of engine oil will be consumed while driving. In th e 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, when towing, or when driving
while accelerating or decelerating frequently ●
When leaving the engine idling for a long time, or when drivin g frequently through
heavy traffic ■
After changing the engine oil

The coolant level is satisfactory if it is between the “F” and “L” lines on the reser-
voir when the engine is cold.
Reservoir cap
“F” line
“L” line If the level is on or below the “L” line, add
coolant up to the “F” line. ■
Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high qua lity 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 % deion-
ized water. (Minimum temperature: -31  F [-35  C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55 % coolant and 45 % deion-
ized water. (Minimum temperature: -44  F [-42  C])
For more details about engine coolant, contact your Lexus dealer. ■
If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine c oolant 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.Engine coolant 1

WARNING ■
When the engine is hot
Do not remove the radiator cap, or 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.

Maintenance and care Check the radiator and condenser and clear any foreign objects.
If either of the above parts is extremely dirty or you are not sure of their condi-
tion, have your vehicle checked by your Lexus dealer.
■
Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN” lines
on the tank. 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 cool-
ing. Be sure to read the antifreeze or coolant label.■
If you spill coolant
Be sure to wash it off with water to pr event it from damage to parts or paint.
Radiator and condenser WARNING ■
When the engine is hot
Do not touch the radiator or condenser as they may be hot and cause serious injuries,
such as burns.

Adding fluid
Make sure to check the fluid type and prepare the necessary item. ■
Refilling brake fluid
Turn the engine switch off.
Depress the brake pedal more than 40 times.
Remove the reservoir cap by hand. Ad d 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 dang erous loss of braking efficiency. Use only
newly opened brake fluid. Fluid type FMVSS No.116 DOT 3 or SAE J1703 brake fluid
Items Clean funnel
WARNING ■
When filling the reservoir
Take care because brake fluid can harm yo ur hands or eyes and damage painted sur-
faces. If fluid gets on 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 or when
the fluid level in the accumulator is high. If the reservoir needs freq uent refilling, it may
indicate a serious problem. 1
