WARNING
The engine compartment contains many
mechanisms and fluids that may move
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.

3336-3. Do-it-yourself maintenance

Maintenance and care
Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.
If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. ( P.368)
 The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. ( P.85)
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-infor-
mation display.
QRoutine tire inflation pressure checks
The tire pressure warning system does not
replace routine tire inflation pressure
checks. Make sure to check tire inflation
pressure as part of your routine of daily
vehicle checks.
QTire inflation pressure
OIt may take a few minutes to display the
tire inflation pressure after the power
switch is turned to ON mode.
It may also take a few minutes to display
the tire inflation pressure after inflation
pressure has been adjusted.
OTire inflation pressure changes with tem-
perature. The displayed values may also
be different from the values measured
using a tire pressure gauge.
QSituations in which the tire pressure
warning system may not operate prop-
erly
OIn the following cases, the tire pressure
warning system may not operate prop-
erly.
• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is
not an OE (Original Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehi-
cle, particularly around the wheels or
wheel housings.
• If the tire inflation pressure is extremely
higher than the specified level.
• If wheel without tire pressure warning valves and transmitters are used.
• If the ID code on the tire pressure warn- ing valves and transmitters is not regis-
tered in the tire pressure warning
computer.
OPerformance may be affected in the fol-
lowing situations.
• Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates
strong radio waves or electrical noise
• When carrying a portable radio, cellular
phone, cordless phone or other wireless
communication device
If tire position information is not correctly
displayed due to the radio wave conditions,
the display may be corrected by driving and
changing the radio wave conditions.
OWhen the vehicle is parked, the time
taken for the warning to start or go off
could be extended.
OWhen tire inflation pressure declines rap-
idly for example when a tire has burst, the
warning may not function.
Tire pressure warning system

3627-2. Steps to take in an emergency
When using a flat-bed truck to trans-
port the vehicle, use tire strapping
belts. Refer to the owner’s manual of
the flat-bed truck for the tire strapping
method.
In order to suppress vehicle movement
during transportation, set the parking
brake and turn the power switch off.
Fluid leaks under the vehicle.
(Water dripping from the air condi-
tioning after use is normal.)
 Flat-looking tires or uneven tire
wear
 Engine coolant temperature gauge
continually points higher than nor-
mal.
 Changes in exhaust sound
 Excessive tire squeal when corner-
ing
 Strange noises related to the sus-
pension system
 Pinging or other noises related to
the hybrid system
 Engine missing, stumbling or run-
ning roughly
 Appreciable loss of power
 Vehicle pulls heavily to one side
when braking
NOTICE
QTo prevent damage to the vehicle
when towing using a wheel-lift type
truck
ODo not tow the vehicle from the rear
when the power switch is off. The
steering lock mechan ism is not strong
enough to hold the front wheels
straight.
OWhen raising the vehicle, ensure ade-
quate ground clearance for towing at
the opposite end of the raised vehicle.
Without adequate clearance, the vehi-
cle could be damaged while being
towed.
QTowing with a sling-type truck
Do not tow with a sling-type truck to pre-
vent body damage.
Using a flatbed truck
NOTICE
QTo prevent damage to the vehicle
when towing with a sling-type truck
Do not tow with a sling-type truck, either
from the front or rear.

symptoms, your vehicle probably
needs adjustment or repair. Con-
tact your Lexus dealer as soon as
possible.
