Before driving
Closing the fuel tank cap
When replacing the fuel tank cap,
turn it until a clicking sound is
heard.
After releasing your hand, the cap
will turn slightly to the opposite
direction.
nFuel types

higher)
nFuel tank capacity (reference)
17.2 gal. (65 L, 14.3 Imp.gal.)
nWhen the fuel filler door opener is inoperable
The lever can be used to open the fuel filler
door if the fuel filler door cannot be opened
using the inside switch because the battery is
discharged or for any other reason.

1-5. Refueling
CAUTION
nRefueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do so, may
result in death or serious injury.
lTouch the vehicle or some other metal surface to discharge any static electricity.
Sparks resulting from discharging static electricity may cause the fuel vapors to
ignite.
lAlways hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened. Wait until
the sound cannot be heard before fully removing the cap. In hot weather, pressur-
ized fuel may spray out the filler neck and cause injury.
lDo not allow anyone that has not discharged static electricity from their bodies to
come close to an open fuel tank.
lDo not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
lDo not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
lDo not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition hazard.
nWhen replacing the fuel cap
Do not use anything but a genuine Lexus fuel tank cap designed for your vehicle.
Failure to do so may cause a fire or other incident which may result in death or seri-
ous injury.
NOTICE
nRefueling
Do not spill fuel during refueling.
Failing to do so may damage the vehicle, such as causing the exhaust systems to
operate abnormally or damaging fuel system components or the vehicle's painted
surface.

2-5. Driving information
Cargo and luggage
Capacity and distribution
Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) — (Total weight of occupants)
Steps for Determining Correct Load Limit ⎯
(1) Locate the statement “The combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs.” on your vehicle’s placard.
(2) Determine the combined weight of the driver and passengers that will
be riding in your vehicle.
(3)Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
(4)The resulting figure equals the available amount of cargo and luggage
load capacity.
For example, if the “XXX” amount equals 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.)
(5)Determine the combined weight of luggage and cargo being loaded
on the vehicle. That weight may not safely exceed the available cargo
and luggage load capacity calculated in Step 4.
Take notice of the following information about storage precautions, cargo
capacity and load.
lStow cargo and luggage in the trunk whenever possible. Be sure
all items are secured in place.
lBe careful to keep the vehicle level. Placing the weight as far for-
ward as possible helps maintain vehicle balance.
lFor better fuel economy, do not carry unnecessary weight.

Maintenance and care Emission inspection and maintenance (I/M) programs
Some states have vehicle emission inspection programs which include
OBD (On Board Diagnostics) checks. The OBD system monitors the oper-
ation of the emission control system.
nIf the malfunction indicator lamp comes on
The OBD system determines that a problem 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.
nYour vehicle may not pass the I/M test:
lWhen the battery is disconnected or discharged
Readiness codes that are set during ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may
not be completely set.
lWhen the fuel tank cap is loose
The malfunction indicator lamp comes on as a temporary mal-
function and your vehicle may not pass the I/M test.
nWhen the malfunction indicator lamp goes off after several driv-
ing trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
nIf your vehicle does not pass the I/M test
Contact your Lexus dealer to prepare the vehicle for re-testing.

4-3. Do-it-yourself maintenance
nEffects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
lReduced fuel efficiency
lReduced driving comfort and tire life
lReduced safety
lDamage to the drive train
If a tire needs frequent refilling, have it checked by your Lexus dealer.
nInstructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
lCheck only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been driven for
more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure
reading.
lAlways use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation pressures
that are even just a few pounds off can degrade ride and handling.
lDo not bleed or reduce tire inflation pressure after driving. It is normal for the
tire inflation pressure to be higher after driving.
lNever exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is bal-
anced.

When trouble arises
387
5-2. Steps to take in an emergency
nIf the malfunction indicator lamp comes on while driving
First check the following:
lIs the fuel empty?
If it is, fill the fuel tank immediately.
lIs the fuel tank cap loose?
If it is, tighten it securely.
The lamp will go off after taking several driving trips.
If the lamp does not go off even after several trips, contact your Lexus dealer as
soon as possible.
nElectric power steering warning light
When the battery is low or when the voltage drops temporarily, the electric power
steering warning light may come on.
nFront passenger detection sensor and passenger seat belt reminder and warning
buzzer
lIf luggage is placed on the front passenger seat, the front passenger detection
sensor may cause the warning light to flash and the warning buzzer to sound,
even if a passenger is not sitting in the seat.
lIf a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.
nWhen the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pressing the
satellite switch does not turn off the tire pressure warning light.
nThe tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such as natural air
leaks or tire inflation pressure changes caused by temperature. In this case, adjust-
ing the tire inflation pressure will turn off the warning light (after a few minutes).
nWhen a tires is replaced with a spare tire
The compact spare tire is not equipped with the tire pressure warning valve and
transmitter. If a tire goes flat, the tire pressure warning light will not turn off even
though the flat tire is replaced with the spare tire. Replace the spare tire with the
repaired tire and adjust the proper tire inflation pressure. The tire pressure warning
light will turn off after a few minutes.
