turn it until you hear a click.
The cap will turn slightly to the
opposite direction when released.
Hang the fuel tank cap on the
back of the fuel filler door.
■Fuel types (Gasoline engine)
Use unleaded gasoline. (Octane rating 87 [Research Octane Number 91] or
higher)
■ Fuel types (Flex-fuel engine)
Use unleaded gasoline (Octane rating 87 [Research Octane Number 91] or

1-7. Safety information

Before driving
Your vehicle is equipped with
ADVANCED AIRBAGS designed based
on US motor vehicle safety standards (FMVSS208). The airbag sys-
tem controls airbag deployment power for the driver and right front
passenger. The driver airbag system consists of the driver seat’s
position sensor etc. The front pass enger’s airbag system consists of
the front passenger occupant classification sensor etc.
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. The
airbag sensor assembly consists of a safing sensor and an airbag
sensor.
Front bench type seat: The SRS airbags are designed to protect the
driver and right front passenger, and they are not designed to protect
an occupant in the front center seating position.
In certain types of severe frontal or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to help rest rain the motion
of the occupants. Side airbags

CAUTION
■Exhaust gases
Exhaust gases include harmful carbon monoxide (CO) that is colorless and
odorless. Inhaling exhaust gases may lead to death or a serious health haz-
ard.
●If the vehicle is in a poorly ventilated area, stop the engine. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle.
This may lead to death or a serious health hazard.
● The exhaust should be checked occasionally. If there is a hole or crack
caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by your Toyota dealer.
Failure to do so may allow exhaust gases to enter the vehicle, resulting in
death or a serious health hazard.
● Toyota does not recommend occupying the rear cargo area when it is fitted
with a slide-in camper, camper shell or other type cover while the engine is
running. This caution applies to bot h driving and stopped or parked situa-
tions with the engine running. Particular care should be taken to prevent
exhaust gases from entering camper bodies, trailers or other enclosures
on or around your vehicle. If exhaust fumes are detected, open all win-
dows and thoroughly ventilate the area.
■ When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift
lever or depress the accelerator pedal, which could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicle, leadin\
g to
death or a serious health hazard.
■ When braking the vehicle
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one
side of the vehicle to brake differently than the other side. Also the parking
brake may not securely hold the vehicle.

■Toyota recommends the use of cleaner burning gasoline
Cleaner burning gasoline, including reformulated gasoline that contains oxy-
genates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in
many areas.
Toyota recommends the use of cleaner burning gasoline and appropriately
blended reformulated gasoline. These types of gasoline provide excellent
vehicle performance, reduce vehicle emissions and improve air quality.
■ Toyota does not recommend blen ded gasoline (Gasoline engine)
● Toyota allows the use of oxygenate blended gasoline where the oxygen-
ate content is up to 10% ethanol or 15% MTBE.
● If you use gasohol in your Toyota, be sure that it has an octane rating no
lower than 87.
● Toyota does not recommend the use of gasoline containing methanol.
■ Toyota does not recommen d gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.
The malfunction indicator lamp on the instrument cluster may come on. If
this happens, contact your Toyota dealer for service.
■ Toyota does not recommend blende d gasoline (Flex-fuel engine)
Do not use non-specified fuels such as the following.
• Fuels containing methanol.
• Fuels with more than 85% ethanol.
■ Toyota does not recommend the use of after-market fuel additives
(Flex-fuel engine)
Do not use any after-market fuel additives when repeatedly refueling with
E85, as some after-market fuel additives are not compatible with E85.

NOTICE
■
Notice on fuel quality
●Do not use improper fuels.
If improper fuels are used the engine will be damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic
converters causing the emission control system to malfunction.
● Gasoline engine: Do not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.
● Use of unleaded gasoline with an octane rating lower than 87 may result in
engine knocking. Persistent knocking can lead to engine damage and
should be corrected by refueling with higher octane unleaded gasoline.
■ When use of non-specified fuels (Flex-fuel engine)
The use of non-specified fuels will have a negative impact on starting and
driving performance, and will cause damage to the fuel system components.
Therefore, do not add fuels such as the following.
• Fuels containing methanol
• Fuels with more than 85% ethanol
■ Fuel-related poor driveability
If after using a different type of fuel, poor driveability is encountered (poor
hot starting, vaporization, engine knocking, etc.), discontinue the use of that
type of fuel.
■ When refueling
Take care not to spill fuel.
It can damage your vehicle’s paint.
