CAUTION
■Refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do so may
r
esult in death or serious injury.
• Touch the vehicle or some other metal surf ace to dischar
ge any static electricity.
Sparks resulting from discharging static electricity may cause the fuel vapors to
ignite.
• Always hold the grip on the fuel tank cap and turn it slowly to remove it. A whooshin
g sound may be heard when the fu el tank cap is loosened. Wait until
the sound cannot be heard before fully removing the cap. In hot weather, pres -
surized fuel may spray out the filler neck and cause injury.
• Do not allow any one that has not discharge
d static electricity from their bodies,
to come close to an open fuel tank.
• Do not inhale vaporized fuel. 
Fuel contains substances that are harmful to the human body, if inhaled.
• Do not smoke while refueling the vehicle. 
Doing so may cause the fuel to ignite and cause a fire.
• Do not return to the vehicle or touch an y perso
n or object that is statically
charged. 
This may cause static electricity to build up, resulting in a possible ignition haz -
ard.
■Fuel cap precaution
Do not use anything but a genuine Lexus fuel tank cap designed for your vehicle.
F

ailure to do so may cause a fire or other incident which may result in death or seri -
ous injury.
NOTICE
■Refueling
Observe the following precautions when refueling the vehicle. 
Failing to do so damages the vehicle, su ch
as causing the exhaust systems to oper -
ate abnormally or damaging fuel system c
omponents or the vehicle’s painted sur-
face.
• Do not use any type of gasoline other than as recommended. ( P.373 )
• Do not spill fuel during refueling.

4-3. Do-it-yourself maintenance
■Adding the engine oil
If the oil level is below or near the low
level mark, add engine oil of the same
type as already in the engine.
Make sure to check the oil type and prepare the items needed before adding.
Remove the oil filler cap.
Add engine oil slowly, checking the dipstick.
Return the filler cap and turn the ca
p clockwise until you hear a
click.
It takes about 1.6 qt. (1.5 L, 1.3 lmp.qt.) to raise the oil level from low to full on the
dipstick.
■ Recommended viscosity
Temperature range anticipated before next oil change.
SAE 5W-30 is the best choice for
goo
d fuel economy, and good starting
in cold weather.
If SAE 5W-30 is not available, SAE
1
0W-30 may be used. However, it
should be replaced with 5W-30 at
the next oil change.

Oil viscosity
• “5W” oils are for use in ar
eas where the ambient temperature is -13 F (-
25 C) or above. “10W” oils are fo r areas where the ambient tempera -
ture is -4 F (-
20C) or above. Oils with smaller figures are better for
engine starting in cold we ather and fuel efficiency.
• “XX-30” indicates oil viscosity. O ils with lar

6-1. Specifications
■Lexus recommends the use of gasoline containing detergent additives
●Lexus recommends the use of gasoline that contains detergent additives to
avoid build-up of engine deposits.
●All gasoline sold in the US contains detergent additives to clean and/or keep
clean intake systems.
■Lexus recommends the use of cleaner burning gasoline
Cleaner burning gasoline, including reform ulated gasoline that conta
ins oxygen-
ates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many
ar

eas.
Lexus recommends the use of cleaner burning gasoline and appropriately blended
r
eformulated gasoline. These types of gasoline provide excellent vehicle perfor -
mance, reduce vehicle emissions, and improve air quality.
■Lexus does not recommend blended gasoline
●Lexus allows the use of oxygenate blended gasoline where the oxygenate con -
tent is up to 10% ethanol or 15% MTBE.
●If you use gasohol in your Lexus, be sure that it has an octane rating no lower
than 87.
●Lexus DOES NOT recommend the use of gasoline containing methanol.
■Lexus does not recommend gasoline containing MMT
Some gasolines contain an octane enhanc
ing additive called MMT (Methylcyclo-
pentadienyl Manganese Tricarbonyl).
Lexus DOES NOT recommend the use of gasoline that contains MMT. If fuel con -
taining MMT is used, your emission control system may be adversely affected.
The Malfunction Indicator Lamp on the inst rum
ent cluster may come on. If this hap-
pens, contact your Lexus dealer for service.

NOTICE
■Notice of gasoline quality
●Do not use leaded gasoline. 
Leaded gasoline can cause damage to your vehicle’s three-way catalytic convert -
ers causing the emission control system to malfunction.
●Do not use gasohol other than stated above. 
It will cause fuel system damage or vehicle performance problems.
●Use of unleaded fuel with an octane number or rating lower than stated above
will cause persistent heavy knocking. 
If severe, this will lead to engine damage.
■Fuel-related poor driveability
If after using a different type of fuel, poor driveability is encountered (poor hot start -
ing, vaporization, engine knoc king,
etc.), discontinue the use of that type of fuel.
■When refueling with gasohol
Take care not to spill gasohol: 
It may cause paint damage.
