WA R N I N G
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
●Make sure that the “ACCES-
SORY” or “IGNITION ON” on
the multi-inform ation display
and the “READY” indicator are
both off.
●Keep hands, clothing and tools
away from the moving fans.
ItemsParts and tools●Be careful not to touch the
engine, power control unit, radi-
ator, 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 compart-
ment.
●Do not smoke, c ause sparks or
expose an open flame to fuel or
the 12-volt battery. Fuel and
12-volt battery fumes are flam-
mable.
●Be extremely cautious when
working on the 12-volt battery. It
contains poisonous and corro-
sive sulfuric acid.
■When working near the elec-
tric cooling fans or radiator
grille
Be sure the power switch is OFF.
With the power switch in ON, the
electric cooling fans may auto-
matically start to r un if the air con-
ditioning is on an d/or the coolant
temperature is high. ( P.437)
■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 ai r cleaner filter
removed may cause excessive
engine wear due to dirt in the air.

■After a fuse is replaced
●When installing the lid, make sure
that the tab is ins talled securely.
●If the lights do not turn on even
after the fuse has been replaced,
a bulb may need replacement.
( P.463)
●If the replaced fuse blows again,
have the vehicle inspected by
your Toyota dealer.
■If there is an ove rload in a cir-
cuit
The fuses are designed to blow, pro-
tecting the wiring harness from
damage.
■When replacing light bulbs
Toyota recommends that you use
genuine Toyota pr oducts designed
for this vehicle.
Because certain bulbs are con-
nected to circuits designed to pre-
vent overload, non-genuine parts of
parts not designed for this vehicle
may be unusable.

■To prevent system break-
downs and vehicle fire
Observe the following precau-
tions.
Failure to do so may cause dam-
age to the vehicle, and possibly a
fire or injury.
●Never use a fuse of a higher
amperage rating than that indi-
cated, or use any other object in
place of a fuse.
●Always use a genuine Toyota
fuse or equivalent.
Never replace a fuse with a
wire, even as a temporary fix.
●Do not modify the fuses or fuse
boxes.
NOTICE
■Before replacing fuses
Have the cause of electrical over-
load determined and repaired by
your Toyota dealer as soon as
possible.
Light bulbs
You may replace the follow-
ing bulbs yourself. The diffi-
culty level of replacement
varies depending on the
bulb. If necessary bulb
replacement seems difficult
to perform, contact your
Toyota dealer.
For more information about
replacing other light bulbs,
contact your Toyota dealer.

replaced by your Toyota
dealer
 Headlights/daytime running
lights
 Parking lights
 Front turn signal lights
 Tail lights
 Stop lights
 High mounted stoplight
 License plate lights
■LED light bulbs
The lights other than the front side
marker lights, rear turn signal lights,
rear side marker lights and back-up
lights consist of a number of LEDs.
If any of the LEDs burn out, take
your vehicle to your Toyota dealer to
have the light replaced.
■Condensation build-up on the
inside of the lens
In certain situatio ns, such as when
driving in the rain or when washing
the vehicle, condensation may form
on the inner side of the headlight
lens and other li ghts. As each light has a ventilation hole, moist air may
enter. If the ambien
t temperature is
low, condensation may form tempo-
rarily, but it will dissipate as the
inside of the light is warmed up. As
the condensation is due to a phe-
nomenon similar to windows fogging
in the rain, it does not indicate a
malfunction.
Contact your Toyota dealer for more
information in t he following situa-
tions:
●Large drops of water have built up
on the inside of the lens.
●Water has built up inside the
headlight.
