2-4. Using other driving systems
When the system is activated in the situations described above, there is also a possi-
bility that the seat belts will retract quickly and the brakes will be applied with a force
greater than normal. When the seat belt is locked in the retracted position, stop the
vehicle in a safe place, release the seat belt and refasten it.
nObstacles not detected

Radio Frequency Radiation Exposure. This equipment complies with FCC radiation
exposure limits set forth for uncontrolled equipment and meets the FCC radio fre-
quency (RF) Exposure Guidelines in Supplement C to OET65. This equipment has
very low levels of RF energy that it deemed to comply without maximum permissive
exposure evaluation (MPE). But it is desirable that it should be installed and oper-
ated with at least 7.9 in. (20 cm) and more between the radiator and person’s body
(excluding extremities: hands, wrists, feet and legs).
This transmitter must not be co-located or operated in conjunction with any other
antenna or transmitter.
nCaution while driving
Do not connect portable players or operate the controls.

Maintenance and care
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precautions:
nWhen working on the engine compartment
lKeep hands, clothing and tools away from the moving fan and engine drive belt.
lBe careful not to touch the engine, radiator, exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other fluids may also be hot.
lDo not leave anything that may burn easily, such as paper or rags, in the engine
compartment.
lDo not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable.
lBe extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
nWhen working near the electric cooling fan or radiator grille
Be sure the “ENGINE START STOP” switch is off.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fan may automatically start to run if the air conditioning is on and/or the
coolant temperature is high. (→P. 4 7 2 )
nSafety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in the eyes.
NOTICE
nIf you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to
dirt in the air. Also a backfire could cause a fire in the engine compartment.

Maintenance and care
nIf the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, 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 systems.
CAUTION
nWhen 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
nWhen 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.
nIf you spill coolant
Be sure to wash it off with water to prevent damage to parts or paint.

4-3. Do-it-yourself maintenance
Radiator and condenser
Check the radiator and condenser, and clear away 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
nChecking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.
nAdding fluid
Make sure to check the fluid type and prepare the necessary item.
CAUTION
nWhen the engine is hot
Do not touch the radiator or condenser, as they may be hot and cause burns.
Fluid typeFMVSS No.116 DOT 3 or SAE J1703
ItemsClean funnel

5-2. Steps to take in an emergency
If your vehicle overheats
If your engine overheats:
Stop the vehicle in a safe place and turn off the air conditioning
system.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam sub-
sides and then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Remove the engine compartment cover. (→P. 464)
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the temperature of the engine (shown on the instru-
ment panel) begins to fall and then stop the engine.
If the fan is not operating:
Stop the engine immediately and call your Lexus dealer.
After the engine has cooled
down sufficiently, check the
engine coolant level and inspect
the radiator core (radiator) for
any leaks.
