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.

Cargo & luggage
Capacity and distribution
Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) - (T
otal weight of occupants)
■ Steps for determining corr
ect load limit
Locate the statement “The combin ed w
eight of occupants and
cargo should never exceed xxx pounds” on your vehicle’s plac -
ard.
Determine the combined weight of the driv
er and passengers
that will be riding in your vehicle.
Subtract the combined weight of the driver and passengers from
xxx pounds or xxx kilograms
The resulting figure equals the available amount of car
go and lug-
gage load capacity.
For example, if the “xxx” amount equa ls 1400 lbs. and there will be five
150 lb. passengers in your vehicle, the amount of available cargo and
luggage load capacity is 650 lbs. 1400 - 750 (5 150) = 650 lbs.
Take notice of the following information about stowage precautions, cargo
capacity and load.
When stowing cargo and luggage in the vehicle, observe the following precau-
tions:
• Put cargo and luggage in the trunk wh en at all possible. Be sure all
items are secured in place.
• Be careful to keep the vehicle level. Placing the w
eight as far forward
as possible helps maintain vehicle balance.
• For better fuel economy, do not carry unnecessary weight.

Maintenance and care
Emission inspection and maintenance (I/M) programs
Some states have vehicle emission in spection programs which include OBD
(On-Board Diagnostics) checks.

The OBD system monitors the operation of the emission control system.
■ If the malfunction indicator lamp comes on
The OBD system determines that a pr
oblem exists somewhere in the
emission control system. Your vehicle may not pass the I/M test and
may need to be repaired. Contact your Lexus dealer to service the
vehicle.
■ Y
our vehicle may not pass the I/M test:
●When the battery is disconnected or discharged
Readiness codes that are set during or
dinary driving are erased.
Also, depending on your driving habits, the readiness codes may not
be completely set.
●When the fuel tank cap is loose
The malfunction indicator lamp co mes on as tempor
ary malfunction
and your vehicle may not pass the I/M test.
■ When the malfunction indicator lamp goes off after se
veral driving
trips
The error code in the OBD system wi ll not be clear
ed unless the vehi-
cle is driven 40 or more times.
■ If y
our vehicle does not pass the I/M test
Contact your Lexus dealer to prep ar
e the vehicle for re-testing.

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.

Maintenance and care
■Tire inflation pressure check interval
You should check the tire inflation pressur
e every two weeks, or at least once a
month. 
Do not forget the spare. The inflation pressure for the spare tire should be the same
as
that for the standard tire. ( P.364 )
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
•Wasting fuel
• Reducing driving comfort and tire life
• Making your vehicle less safe to drive
If a tire needs frequent refilling, have it checked by your Lexus dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observing the following;
• Check only when the tires are cold. 
If your vehicle has been parked for at least 3 hours and has not been driven for
mor
e than 1 mile or 1.5 km since, you will get an accurate cold tire inflation pres -
sure reading.
• Always use a tire pressure gauge. 
The appearance of the tire can be misleadi n
g. In addition, tire inflation pressures
that are even just a few pounds off can degrade ride and handling.
• Do not bleed or reduce tire inflation pressure after driving. 
It is normal for the tire inflation pressure to be higher after driving.
• Never exceed the vehicle weight capacity. 
Passengers and luggage weight should be pla
ced so that the vehicle is bal-
anced.

5-2. Steps to take in an emergency
■If the electronic engine control system warning light remains on while driving
First check the following:
• Check fuel level, if the fuel tank is empty, refuel immediately.
• Check the fuel tank cap is loose tighten it securely.
The light will go off after driving regularly for some time.
If the light does not go off even after several trips, contact your Lexus dealer as soon
a
s possible.
■Front passenger detection sensor an d passenger’s seat belt reminder
●If luggage is placed on the front passenger seat, the front passenger detection
sensor may cause the warning light to flash and a chime to sound, even if a pas -
senger is not sitting in the seat.
●If a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.
CAUTION
■If both the ABS and brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Lexus dealer. The
v

ehicle will become extremely unstable during braking, and the ABS system may
fail, which could cause an accident resulting in death or serious injury.
