■FCC WARNING
This equipment complies with FCC/IC radiation exposure limits set forth for an
uncontrolled environment and meets the FCC radio frequency (RF) Exposure
Guidelines in Supplement C to OET65 and RSS-102 of the IC radio frequency
(RF) Exposure rules. 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 installe d and operated keeping the radiator at least
7.9 in. (20 cm) or more away from person’s body (excluding extremities: hands,
wrists, feet and ankles).
Cet équipement est conforme aux li mites d’exposition aux rayonnements
énoncées pour un environnement non co ntrôlé et respecte les règles les
radioélectriques (RF) de la FCC lignes directrices d’exposition dans le
Supplément C à OET65 et d’exposition aux fréquences radioélectriques (RF)
CNR-102 de l’IC. Cet équipement émet une énergie RF très faible qui est
considérée conforme sans évaluation de l’exposition maximale autorisée.
Cependant, cet équipement doit être installé et utilisé en gardant une distance de
20 cm ou plus entre le dispositif rayonnant et le corps (à l’exception des
extrémités: mains, poignets, pieds et chevilles).
For vehicles sold in the U.S.A.
Changes or modifications no t expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

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.
■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 driv-
ing as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine
compartment.
●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
corrosive 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
automatically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( P. 6 3 6 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from get-
ting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to
dirt in the air.

The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir wh en the engine is cold.
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the “LOW”
line, add coolant up to the “FULL” line.
(  P. 76 1 )
■Coolant selection
Only use “Toyota Super Long Life Coolant” or a 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 engine coolant, contact your Lexus dealer.
■If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine 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 system.

CAUTION
■When the engine is hot
Do not touch the radiator or condenser as they may be hot and cause serious inju-
ries, such as burns.

When trouble arises
7-2. Steps to take in an emergency
If your vehicle overheats
Stop the vehicle in a safe place and turn off the air conditioning system,
and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled down sufficiently, inspect the hoses and
radiator core (radiator) for any leaks.
Radiator
Cooling fans
If a large amount of coolant leaks,
immediately contact your Lexus
dealer.
The following may indicate that your vehicle is overheating.
●The needle of the engine coolant temperature gauge ( P. 81) enters
the red zone or a loss of engine power is expe rienced. (For example,
the vehicle speed does not increase.)
●Steam is coming from under the hood.
