suddenly, become hot, or become elec-
trically energized. To avoid death or seri-
ous injury, observe the following
precautions.
QWhen working on the engine com-
partment
OMake sure that the “IGNITION ON”
on the multi-information display and
the “READY” indicator are both off.
OKeep hands, clothing and tools away
from the moving fan and engine drive
belt.
OBe careful not to touch the engine,
power control unit, radiator, exhaust
manifold, etc. right after driving as they
may be hot. Oil and other fluids may
also be hot.
ODo not leave anything that may burn
easily, such as paper and rags, in the
engine compartment.
ItemsParts and toolsODo not smoke, cause sparks or expose
an open flame to fuel. Fuel fumes are
flammable.
QWhen working near the electric cool-
ing fan or radiator grille
Be sure the power switch is off.
With the power switch in 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.326)
QSafety glasses
Wear safety glasses to prevent flying or
falling material, fluid spray, etc. from get-
ting in your eyes.
NOTICE
QIf you remove the air cleaner filter
Driving with the air cleaner filter
removed may cause excessive engine
wear due to dirt in the air.

3326-3. Do-it-yourself maintenance
Rotate the tires in the order shown.
To equalize tire wear and extend tire life,
Lexus recommends that tire rotation is car-
ried out at the same interval as tire inspec-
tion.
Do not fail to initialize the tire pressure
warning system after tire rotation.
QWhen rotating the tires
Make sure that the power switch is off. If the
tires are rotated while the power switch is in
ON mode, the tire position information will
not be updated.
If this accidentally occurs, either turn the
power switch to off and then to ON mode,
or initialize the system after checking that
the tire pressure is properly adjusted.
WARNING
QWhen inspecting or replacing tires
Observe the following precautions to
prevent accidents.
Failure to do so may cause damage to
parts of the drivetrain as well as danger-
ous handling characteristics, which may
lead to an accident re sulting in death or
serious injury.
ODo not mix tires of different makes,
models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
ODo not use tire sizes other than those
recommended by Lexus.
ODo not mix differently constructed
tires (radial, bias-belted or bias-ply
tires).
ODo not tow if your vehicle has a com-
pact spare tire installed.
ODo not mix summer, all season and
snow tires.
ODo not use tires that have been used
on another vehicle.
Do not use tires if you do not know
how they were used previously.
NOTICE
QDriving on rough roads
Take particular car e when driving on
roads with loose surfaces or potholes.
These conditions may cause losses in tire
inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving
on rough roads may cause damage to
the tires themselves, as well as the vehi-
cle’s wheels and body.
QLow profile tires (18-inch/19-inch
tires)
Low profile tires may cause greater dam-
age than usual to the tire wheel when
sustaining impact from the road surface.
Therefore, pay attention to the following:
OBe sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
OAvoid potholes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
QIf tire inflation pressure of each tire
becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.
