Before driving
PRIUS_U_(OM47614U)
Your vehicle is equipped with “ADVANCED AIRBAGS” designed
based on US motor vehicle safety standards (FMVSS208). The air-
bag system controls air
bag deployment power for the driver and 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.
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.
■ If the SRS airbags deploy (inflate)
● Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the seats, and parts of the front and rear pillars and roof side
rail, may be hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.

PRIUS_U_(OM47614U)
NOTICE
■Cleaning detergents
Do not use the following types of detergent, as they may discolor the vehicle
interior or cause streaks or damage to painted surfaces.
● Non-seat portions: Organic substances such as benzine or gasoline, alka-
line or acidic solutions, dye, or bleach.
● Seats: Acidic solutions, such as thinner, benzine, or alcohol.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces.
● Remove any dust or dirt on leather surfaces immediately.
● Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl, plastic, or that contain wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components under the floor of the vehicle, and
may also cause the body to rust.
■ Cleaning the inside of the rear window
● Do not use glass cleaner to clean the rear window, as this may cause
damage to the rear window defogger heater wires. Use a cloth dampened
with lukewarm water to gently wipe the window clean. Wipe the window in
strokes running parallel to the heater wires.
● Be careful not to scratch or damage the heater wires or antenna.

■
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 blended gasoline
● 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 recommend 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.

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.
● Do not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.
● Using unleaded gasoline with an octane number or rating lower than that
stated here will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■ Fuel-related p oor 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 with gasohole
Take care not to spill gasohol. It can damage your vehicle’s paint.
