NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indi-
cates the maximum engine speed.
●The engine may be overheating if the engine coolant temperature gauge is in the
red zone (“H”). In this case, immediately stop the vehicle in a safe place. Check
the engine after it has cooled completely. ( P. 363)
■While driving
●When the voltmeter indicates more than 19 V or less than 9 V, the battery may be
malfunctioning. Have your vehicle checked at your Lexus dealer.
●When the engine oil pressure gauge do es not work properly, immediately stop
the engine and contact your Lexus dealer.

4-3. Do-it-yourself maintenance
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury.
■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, inverter, 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 or rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
■When working near the electric cooling fan or radiator grille
Be sure the ignition is off. With the ignition in on, the electric cooling fan may auto-
matically start to run if the air conditioning is on and/or if the coolant temperature is
high.
(  P. 2 8 3 )
■When working on or under the vehicle
●Do not get under the vehicle with just the jack supporting it.
Always use automotive jack stands or other solid supports.
●Use eye protection 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. Also a backfire could cause a fire in the engine compartment.

Maintenance and care
■Recommended viscosity
SAE 5W-30 is the best choice for
good fuel economy and good
starting in cold weather.
*: If SAE 5W-30 is not available,SAE 10W-30 may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.
■ How to read oil container labels
Some oil containers are labeled wi th ILSAC certification marks that
help you to select the proper oil.

5-2. Steps to take in an emergency
■When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire
pressure warning reset switch does not turn off the tire pressure warning light.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural
air leaks or tire inflation pressure changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light.
■If the tire pressure warning system is inoperative
The tire pressure warning system may become inoperative in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and transmitters are used.
●If the ID code on the tire pressure warning valves and transmitters is not regis-
tered.
●If electronic devices or facilities using similar radio wave frequencies are nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If the tire pressure warning select switch is set to a different tire setting.
●If there is a lot of snow or ice on the vehicle, in particular around the wheels or
wheel housings.
●If non-genuine Lexus wheels are used.
●If tire chains are used.
●If the spare tire is in a location subject to poor radio wave signal reception.
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or higher.
■If the tire pressure warning light blinks
If the tire pressure warning light blinks when the ignition key is turned to the “ON”
position, have it checked by your Lexus dealer.
■Changing the engine oil (U.S.A. only)
Make sure to reset oil change system

Vehicle specifications
Lubrication system
*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity:
● The 5W portion of the oil viscosity rating indicates the characteristic of
the oil which allows cold startability . Oils with a lower value before the W
allow for easier starting of the engine in cold weather.
● The 30 in 5W-30 indicates the oil viscosity when the oil is as its operating
temperature. An oil with a higher viscosity may be better suited if the
vehicle is operated at high speeds, or under extreme load condition.

Warning: The temperature grades for this tire are established for a tire that
is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
