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.
■When working on the engine com-
partment
●Keep hands, clothi ng 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. Fuel fumes are
flammable.
■When working near the electric cool-
ing fan or radiator grille
Be sure the engine switch is off.
With the engine switch in ON, the elec-
tric cooling fan may automatically start to
run if the air conditioning is on and/or the
coolant temperature is high. ( P.277)
ItemsParts and tools■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.

Maintenance and care
Tires cannot be rotated.
When run-flat tires are installed, the
vehicle can be driven for a maximum of
100 miles (160 km) at a speed below
50 mph (80 km/h) after any tire goes
flat. (However, the vehicle speed may
not increase to near 50 mph [80
km/h] depending on weather or driv-
ing conditions.)
A run-flat tire has a mark on
the sidewall.
Make sure to replace the flat tire before
the vehicle has been driven for near 100
miles (160 km). Also, do not use a repaired
tire.
■Run-flat tires
●The run-flat tires are for only this vehicle.
Do not use the tires on other vehicles.
●Do not mix run-flat tires and normal tires.
●If non-genuine Lexus wheels are used, it
may be impossible to sufficiently demon-
strate the performanc e of run-flat tires.
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.319) 
The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. ( P.79)
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-infor-
mation display.
■Routine 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.
■Situations in which the tire pressure
warning system may not operate prop-
erly
●In 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.

4Press or of the meter con-
trol switches and select “TPWS
SET”, then press “OK”.
5 Press or of the meter con-
trol switches and select “Change
wheel set”. Then press and hold
“OK” until the tire pressure warn-
ing light starts blinking.
The change wheel set mode is activated
and registration is started.
A message is displaye d on the multi-infor-
mation display, and “--” is displayed for
inflation pressure of e ach tire. Then, the tire
pressure warning light blinks rapidly for
approximately 1 minute and stays on.
6 Drive the vehicle at 25mph (40
km/h) or more for approximately
10 to 30 minutes.
When registration is completed, the tire
pressure warning light will go off and the
inflation pressure of e ach tire will be dis-
played on the multi-information display.
The time elapsed before registration is
completed differs according to the driving
condition and environment.
■Canceling the change wheel set mode
●If turning the engine switch off when in
the change wheel set mode before driv-
ing, the change wheel set mode is can-
celed.
●After driving when in the change wheel
set mode, the change wheel set mode
cannot be canceled. To cancel the mode, perform the procedure for ID code regis-
tration again and turn the engine switch
off before driving.
●If the change wheel set mode is canceled,
the ID codes that have already been reg-
istered are communicated. When com-
munication is finished, the tire pressure
warning light will turn off.
■When ID code registration may not
operate properly
●Do not move the vehicle backward
during registration. Re
gistration is started
again from the beginning and it may take
longer than usual.
●When another vehicle is running the side
of the vehicle such as in heavy traffic, it
may take longer to detect the vehicle’s
tire pressure warnin g valves and trans-
mitters.
●If tire pressure warning valves and trans-
mitters are in the vehicle, the ID codes
may not be registered.
If registration takes long time, perform the
procedure for ID code registration again
after parking the vehicle for 20 minutes.
If the ID codes cannot be registered even
when performing the above procedure,
contact your Lexus dealer.
