4RUNNER_U
CAUTION:
This equipment complies with FCC/IC radiation exposure limits set forth for
an uncontrolled environment and meets the FCC radio frequency (RF) Expo-
sure Guidelines in Supplement C to OET65 and RSS-102 of the IC radio fre-
quency (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 installed and operated
keeping the radiator at least 20 cm or more away from person’s body
(excluding extremities: hands, wrists, feet and ankles).
Cet équipement est conforme aux limites d’exposition aux rayonnements
énoncées pour un environnement non contrôlé et respecte les règles les
radioélectriques (RF) de la FCC lignes directrices d’exposition dans le Sup-
plément 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 dis-
tance de 20 cm ou plus entre le dispositif rayonnant et le corps (à l’exception
des extrémités: mains, poignets, pieds et chevilles).
NOTICE:
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. How-
ever, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
● Reorient or relocate the receiving antenna.
● Increase the separation between the equipment and receiver.
● Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
● Consult the dealer or an experienc ed radio/TV technician for help.

CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, 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 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 and rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting 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. Also, a backfire could cause a fire in the engine com-
partment.

Engine coolantThe coolant level is sati sfactory if it is between the “F” and “L” lines on
the reservoir 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 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 Toyota 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 Toyota dealer test the cap and check for
leaks in the cooling system.
